INFORMATION Uses Characteristic features 126 m@)=4-=) FRFCO-AXIAL CONNECTORS The POB (Push-on Lock Connectors Type B) series consists of high-performance small-size push-on lock coaxial connectors having original coupling parts which were developed for microwave-band use. Mounting and removing can be performed in a shorter time than in the familiar HRM series of small-size coaxial connectors for microwave-band use. In addition, mounting and removing can be performed without using a torque wrench. Therefore, the mount- ing density can be increased. By using the POB series, the adjusting time in sets can be shortened, the maintenance work can be speeded up, and the economical effect is displayed to the fullest. The POB series is suitable for in-unit wiring in wired and wireless communications equipment, broadcasting equipment, radar equipment and electronic measuring instruments, for connections between units, and for input/output terminals of equipment components. In particular, they facilitate the complicated and high- density processing of in-unit wiring and the mounting and removing work in multi-stage unit coupling. More- over, they are most suitable for sets in which it is necessary to ensure excellent transmission charac- teristics. 1. Good performance characteristics The structure and dimensions of the transmission path and the structure in which the center contact and the dielectric materials are fastened have been unified between the POB series and the HRM series. Therefore, the POB series has high-frequency charac- teristics as good as those of the HRM series and mechanical characteristics as stable as those of the HRM series. The coupling part also has a structure with an innovative spring function unit, which has been designed so that the electrical standard surfaces are always in contact, and an outer cylinder which protects the spring function unit and provides excellent protec- tion, thus ensuring high stability and reliability. 2. Mounting and removal are easy. There are the following advantages in mounting and removal in comparison with the HRM series, which is of the screw-lock type. (1) Mounting and removal does not take time and can be carried out almost instanta- neously. (2) Even in a configuration like that of a U link, in which connectors are attached to both ends of a short semi-rigid cable, there is no need to go to the trouble of aligning the coupling depths of both sides when mounting and removing, as is necessary in the HRM series. (3) The structure used is a complete one in which both the center and outer con- tact springs are not damaged even if the cable is twisted when there is incomplete coupling. (4) Since mounting and removal can be performed with the fingers, there is no need to provide spanners or torque wrenches. 3. The mounting density can be raised. The sizes and weights of the POB series are almost the same as those of the HRM series. However, the mounting density can be raised because, unlike the HRM series, torque wrenches are not used, when inserting or withdrawing the POB series. 4. The series is compatibile with the HRM series. The POB series has been given the greatest possible compatibility with the HRM series in the following points. Consequently, when changing over from the HRM series or combining both series, there are very few cases in which the set designs need to be changed, new connecting tools or standard work instruction manuals need to be pro- vided, or guidance is required in the work of connecting the wiring.

Explanation 2: Tapered parts are provided on the spring part of the male coupling part and on the outer diameter part of the female coupling part. Therefore, the spring force is dis- persed in the radial and axial directions, where it operates as the coupling force and as the top touch force on the electrical standard surface, respectively. Explanation 3: Gap a between the inner diameter of the outer cylinder and the outer diameter of the J shell is 0.05mm or less, and its moving angle is suppressed to 23 minutes or less in order to minimize to the utmost the load applied to the contact spring (both the center and outer) even if the cable is twisted in the coupled state. Explanation 4: The dimensions are planned so that the center contacts will not couple together unless part b (5.55) of the J shell is inserted into the outer cylinder (with the exception of the tapered part of the male contact. Therefore, the center contact springs will not be damaged even if the cable is twisted when the coupling state is imperfect. Moreover, since the gap c between the P shell and the outer cylinder is set at 0.2 ~ 0.3 mm and the movable distance of the spring part is suppressed, the outer contact spring will not be damaged. 150g or more/ / Mal P shell ; - . / _ Lop" ale contact / \ \ Electrical Electrical 1 Insulation _ / Female contact standard standard Paneling / J shell surface surface Outer cylinder 128FRRFco.axiAL_ CONNECTORS Performance characteristics Refer to individual drawings Dimension of coupling parts: see P.128.

We also accept orders for designing and production according to special specifications. Client orders are invited. The connectors for semi-rigid cables match two types of cables: .141-inch and .085- inch semi-rigid cables. .141-inch cables should be-used in order to obtain the V.S.W.R. listed on p.129. .085-inch cables, which have good flexibility, are suitable in cases where the wiring is laid with a high density inside the set. In this case, the V.S.W.R. value will be higher than that of the .141-inch cables. 141: for .141-inch semi- rigid cables -85: for .085-inch semi- rigid cables 1+ HRS No. Part No. 8 tS 4 - ~ CL326-0003-6 | POB-J-141 | ifRy \ | ACH Jacks -141: for .141-inch semi- rigid cables Part No. A -85: for .085-inch semi- POB-J-141 | 3.63 rigid cables Panel jacks -141: for .141-inch semi- rigid cables 85: for .085-inch semi- rigid cables 130 b= 18.8 +1 L-type plugs -141: for .141-inch semi- rigid cables PartNo. | Ad 85: for .085-inch semi- "POB-LP-141 3.63 rigid cables POB-LP-S5 2.25 * Standard productm@)=f4-14 FRFco-AXIAL CONNECTORS Connectors for Connectors for flexible cables include those which match RG-55/u, RG-142B/u and flexible cables 3D-2W (Irrax cables) and those which match RG-58/u.

In the POB series, there is almost no change of the V.S.W.R. because the moving angle is suppressed to 23 minutes or less on one side even if twisting occurs, as is described on p.128. Exactly the same applies, naturally, in the original state even after 2000 insertions and with- drawals, which amounts to four times the guaranteed number of insertions and with- drawals. Number of insertions and withdrawals and deterioration of performance characteristics 1. Deterioration of V.S.W.R. The graph below gives typical data on the V.S.W.R. for the original state and when measured after 2000 insertions and withdrawals with twisting. There are almost no differences between the two pairs of data; this proves that deterioration of the V.S.W.R. has not occurred as a result of insertion and withdrawal.

Deterioration of coupling force The graph below shows the deterioration of the coupling force (withdrawal force) caused by insertion and withdrawal. The deterioration is expressed in terms of an exponent, with the average value of 17 samples as the parameter. By the time of the first 100 insertions and withdrawals, the coupling force decreases rapidly to 60% of its initial value. This is because the internal stress is removed within this period and the male and female coupling parts become used to each other. After that, the deterio- ration changes to the usual type of deterioration caused by fatigue of the spring parts and tends towards stable and leisurely deterioration. The failure ratio during the first 100 times is larger in samples with a stronger initial coupling force. Consequently, it is not the case that in products having an initial coupling force near the lower limit of the guaranteed range the coupling force will be halved after 500 insertions and with- drawals.

Note 1: Before soldering, apply preliminary solder on the male contact in advance. Note 2: It is a good idea to make a hole of 0.8, as shown in Fig. (13), at the part where the male contact is to be held in the vice. Note 3: Be careful to perform the soldering speedily so that the tip of the cable insulation will not dis- solve as a result of the heat during soldering. Note 4: The build-up of solder after soldering must be finished unifarmly on the circumference. To check the strength of the soldering, pull the male contact with a force of about 1kg. Note 5: Be careful not to allow gaps to be produced be- tween the insulation and the contact after solder- ing. Note 6: Be careful not to allow the male contact to be soldered in a bent position towards the center con- ductor of the cable. Note 7: It is desirable to use a soldering iron of about 20 ~ 3OW.
