the coaxial connector. No. 4 A connector and connector terminal for a coaxial connector. ^虎疋Non-normal test [Prior Art] The connector is an electromechanical component that realizes electric opening or switching through mechanical action, which is a connection between the roads and the function of transmitting the message or electric energy in the child, so in the son The use of the equipment is quite skin-hard and its reliability also directly affects the performance and operation of the subsystems. A " 日音^ H ^ Takes the eye-catching contact with the more right-handed contact, that is, Affect the normal transmission of telecommunications or electrical energy. As shown in Figure 1 and Figure 2, there are quite a few types of connectors that have been developed for the transmission of telecommunications, such as the US us6, 75i, 3i7B^ invention, which is installed on a mobile phone circuit board. Coaxial on the connector: The socket of the connector includes: "Insulating base u with a connecting space uu a jack m, - mounted in the receiving (4) (1) and fixed on one side The end + 12, the elastic terminal 13' in the accommodating space m and located on the other side, and the metal casing IH covering the periphery of the insulating base u. And the socket! There is a central hole 141 corresponding to the jack ι 2 and corresponding to the elastic terminal 13 in the center. The socket i for the RF test is quite small in size, and the length, width and height are respectively about 3_χ3^χ2_. When the elastic terminal 13 is elastically overlapped with the fixed terminal 12, it is in electrical communication state, so that the telecommunication signal is output from the elastic terminal 13 through the (four) terminal 12 to the telecommunication system of the mobile phone. As shown in Figure 3, before the mobile phone group M294149 is shipped from the factory, it is necessary to use the test connector 2 and the L-way (not shown) connected to the connector to test the telecommunication signal. Is it normal, charm: yes-electric Connected to a connector terminal 21 of a test instrument (not shown); , ; = When the socket 1 is on the ― , # hole 112, the sub-elastically resists the elastic terminal 13 and is forced to separate the fixed terminal 12 from the fixed terminal 12 M ^ in ^ A Λ k唬 will be rotated by the plug and the plug terminal 21 to the test instrument for the heartbeat ^ signal is normal. U / MJ ixi 4 sfl And because the size of the socket 1 is small, the parts are fine and thin, and the valley is tight and the 1(1) is also narrow. Therefore, the 21st plug is connected to the elastic terminal η η±鳊子- 尔"子13, because of too much heart and difficult terminal η, or too long to drink, cut off the elastic terminal 13 or the insulating seat, so the test joint 2 must be right 旦#旦+ Sensitivity, for this reason, has developed a joint terminal, and the conventional joint terminal, in order to be early and large, is assembled by a plurality of discrete elements to bond the elastic body together with the joint. Among the members, the joint terminal therein is more elastic when moving, and it is not only complicated to assemble. The contact of θ 4 is discontinuous and the signal is generated as shown in Fig. 4. A modular and flexible joint terminal has appeared on the surface of the element, such as certificate number No. 26(10) Xinli = a spring terminal 3 contains : "Shell 3!, - Spring 32, and - Thimble 33.

As shown in FIG. 5, in the assembly, the spring 32 and the thimble are sequentially placed into the cover stage 31, and then the re-use tool indents the end portion of the round pipe portion 3 ιι adjacent the tail expansion portion into the inner portion. The limiting portion 313 is configured to limit the thimble 3 3 from being outwardly disengaged from the casing 31 (see FIG. 4). Although, the magazine terminal 3 rabbit. 7 and the child 3 is - independent 杈 group structure, can facilitate the early women's clothing, but it is applied to the connector for transmitting electrical energy, that is, using the conductive battery, so It does not need to pay attention to the rigor of the telecom, so it is known that the post-forging riveting method is used to join, and the limiting portion 313 is only rigidly riveted to the center of the pipe wall. ±The contact precision between the manual parts, the threaded portion 313 is loosely separated and forms a large gap between the thimble 33 and the thimble 33. When it is actuated, it will be shaken, it is difficult to accurately align the socket, which may lead to unstable signals. The image, if only "313 riveting" correction, will cause the material = is not smooth, and even the card can not be moved to cause damage 2: on the ': This spring terminal 3 is not suitable for the transmission of telecommunications On the interface port, the width and diameter of the animal parts are reduced by one side and the left side will be more obvious. . . 4 Inapplicable [New Content] Therefore, the purpose of this new type is to provide a separate modular test-spindle connector and connector terminal 7 M294149, which is 'this test' The connector terminal of the coaxial connector comprises: - an axis extending in opposite first and second directions, a pin sleeve, a pin, an elastic member, and a pin end plug.

Get rid of. 11 M294149 The elastic member 84 is a compression magazine which is mounted in the portion 821 of the pin bushing and has a top abutting δ32 which abuts the end of the center pin 83: M1, and - is sleeved in the A fixed end (10) on the pin end plug 85. When the elastic terminal 43 of the socket 4 overlaps the fixed terminal 42, it is electrically connected, so that the telecommunication signal is connected to the (4) telephone. _ ^ 'When the plug is plugged into the socket 4, the card sliding member: is in the ring groove 441, and the center pin of the joint terminal 8 is extended into the hemp 412, and elastically resists the elastic terminal 43, forcing elasticity The terminal ς is separated from the fixed terminal 42. At this time, the telecommunication signal will be inserted by 'to test whether the telecommunication signal is normal. The inserted two-two pins 83 are also relatively pushed upwards and moved upwards in the opposite direction, so that the elastic member 84 has a reset elastic force. When the joint is pulled out of the socket 4, the middle: 83 will also leave without being pushed. At this time, the center pin 83 can be moved downward by the elastic force of the elastic member 84. The above description shows that the joint of the coaxial connector of the new test is broken == the joint terminal 8 body has a telescopic elasticity; the mixing sleeve, and the lock sleeve 82 is a metal pipe made of a car, which is easier to The control 'makes the inner end of the limit segment 822 from 82:=: fits the middle ', the outer diameter'-the aspect can make the center = to the ground _ telescopic without blocking, on the other hand, there will be no central locking δ3* Too much gap, the telecommunication signal is transmitted to the surface of the limit segment s on the center of the lock s. 822. The surface of the signal can be reduced to ^ ^ 匕 田 读 精准 精准 精准 精准 精准 精准 精准 精准 精准 精准 精准 精准 精准 精准It is also quite simple, so this new model can independently modularize 12 M294149 to the purpose of this new type, and it can be used in the industry to have the effect of precise sensitivity. It can indeed achieve this. This new model is not only an unprecedented innovation, but above Huai. The above is only for the case of the new model, and the scope of the new implementation is limited to the simple equivalent change of the new application = consumption and new description. (4), all still belong to this new patent Within the scope of the cover.
