Abstract

[PROBLEMS] To improve a coupling structure between a male terminal of a socket of a microwave connector for RF communication and an inner conductor of a coaxial cable, to make processing more convenient, and to be manufactured using a simpler and less expensive processing machine. And to reduce the defective product rate.
SOLUTION: Both sides 715 and 716 of a holding part 713 of a male terminal 71 exhibit a symmetrical arc-shaped curve, and both sides 715 and 716 of the holding part 713 are smoothly opposed using a relatively simple and inexpensive processing machine. The inner conductor 811 of the coaxial cable 81 can be firmly clamped and the inner conductor 811 is clamped by the clamping portion 713, and some of the inner conductors corresponding to the slot 714 receive force. When the coaxial cable 81 receives a tension that causes it to be detached from the clamping part 713, the deformed portion of the inner conductor 811 that has fallen into the slot 714 has resistance, so It is relatively rare that the lead wire 811 is detached from the holding portion 713.

Description

The present invention relates to a connector, particularly a socket for a microwave connector for RF communication.

As shown in FIG. 1, a commercially available micro solder connector includes a socket 10 and a plug 20. The bottom of the socket 10 is welded to a circuit board such as a notebook computer, personal digital assistant (PDA), or mobile phone. The plug 20 can be inserted into the socket 10, and the other end is connected to an antenna such as a mobile phone via a signal line for receiving a signal. The socket 10 has a metal outer shell 11 coupled to an insulator 12 at the lower end. The insulator 12 is inserted into the outer shell 11 to form a projecting end 121 at the center, and the interior of the projecting end 121 is coupled to the male terminal 13. The lower end 131 of the male terminal 13 is a piece that extends outside the insulator 12 and the outer shell 11. The plug 20 has a metal shell 21 coupled to the insulator 22, and the hollow portion 221 of the insulator 22 is coupled to the female terminal 23.

The female terminal 23 is composed of two contact pieces 231 that face each other at a slight distance. When the plug 20 is inserted into the socket 10, the two contact pieces 231 of the female terminal 23 of the plug 20 are fitted on both sides of the male terminal 13 of the socket 10 so that the two signal ends are conducted. The shell body 21 is fitted on the outside of the outer shell 11 to make the two ground ends conductive.
The above sockets are all welded to the circuit board, and are subject to restrictions that must be fixed to the circuit board in actual application. It does not apply to the requirements of circuit boards with different standards or circuit arrangements.

As shown in FIG. 2, when the length of the conductor 241 of the plug 24 is insufficient and it is impossible to couple the plug 24 to the socket, another plug is connected via an adapter 14 having male terminals 141 at both ends. By connecting to 25, the plug at the other end of the conducting wire 251 connected to the plug 25 is coupled to the socket.
As shown in FIGS. 3A, 3B, 3C, 3D, 3E, adapters 14, 15, 16, 17, 18 each having male terminals on both sides have various embodiments.

The socket 10 coupled to the circuit board shown in FIG. 1 can be changed to the form of sockets 31, 32, 33, 34 as shown in FIGS. 4A, 4B, 4C, 4D, and its male terminals 311, 321 , 331, 341 are aligned with the conductors 312, 322, 332, 342 and have partition plates 313, 323, 333, 343 on the outer periphery. The partition plates 313, 323, and 333 have screw holes for fixing to the plates of other cases. The plug 24 can be coupled to the socket 33 from one side of the partition plate 333 as shown in FIG. The side of the partition plate 343 has a thread for securing another nut 344 to the plate of the other case.

As shown in FIGS. 6, 7A and 7B, in the microwave connector for RF communication disclosed in Taiwan Utility Model Registration No. 250406 and Japan Utility Model Registration No. 3103794 which the applicant has made rights, Example 1 The socket 40 includes a metal outer shell 41 coupled to the insulator 42, and the insulator 42 is coupled to the male terminal 43. As shown in FIG. 7, the outer shell 41 is coupled to the outer periphery of the insulator 42 and to the conductive wire 44. The conducting wire 44 coupled to the socket 40 and the conducting wire 241 coupled to the plug 24 may be the same conducting wire, so that both ends of the conducting wire 44 have the plug 24 and the socket 40, respectively, and an extension line of the general plug 24 or the socket 40 Can also be used.

As shown in FIGS. 8 and 9, the socket 50 in the second embodiment of the above patent includes a metal outer shell 51 coupled to the insulator 52, and the insulator 52 is coupled to the male terminal 53. As shown in FIG. 8, the metal outer shell 51 is coupled to the outer periphery of the insulator 52 and to the outer periphery of the conducting wire 54. The socket 50 can be fitted with a plug 24. As shown in FIG. 9, one end of the metal outer shell 51 is connected to a carrier tape, which is advantageous for manufacturing and assembly work by production line automation.
The above-described connection between the coaxial cable conductor and the male terminal uses a manual welding method, and thus is not replaced by a processing method using an automated machine, and wastes manpower and time.

FIGS. 10A to 10C show a conventional coaxial microwave connector in which one end of a female terminal 60 of the connector has two contact pieces 61 facing each other and a holding portion 62 on the other end. The two contact pieces 61 are used to hold the male terminal of the socket. The bottom portion of the sandwiching portion 62 has an arc shape, and a bendable member 621 extends upward on one side of the bottom portion. As shown in FIG. 10B, the inner conductor 631 of the coaxial cable 63 is held between the bottom of the holding part 62 and the bent member 621 that is bent.

In the manufacturing method for clamping the inner conductor 631 of the coaxial cable 63 using the bendable member 621 of the clamping part 62 described above, an automated machine can be used as an alternative to the manual processing method by human power. Although relatively saving, the bendable member 621 is fairly long so that it can be smoothly brought into intimate contact with the other end of the arcuate bottom without a relatively sophisticated and expensive folding device. It cannot be bent into a semicircular arc. If the bendable member 621 is not smoothly bent so as to be in close contact with the other end of the arc-shaped bottom of the holding part 62, it affects the function of holding the inner conductor 631, and affects the signal transmission quality of the connector. In other words, it becomes a defective product. The above-described structure that does not require welding is not a structure that couples the male terminal and the coaxial cable, but is used for coupling the female terminal and the coaxial cable.

Therefore, the present invention improves the coupling structure between the male terminal of the socket of the RF communication microwave connector and the inner conductor of the coaxial cable, makes the processing more convenient, and uses a simpler and less expensive processing machine. An object of the present invention is to reduce the defective product rate.

Other objects and functions of the present invention will be described in detail below with reference to the drawings and embodiments.
As shown in FIGS. 11A-11C, the male terminal 71 of the first embodiment of the present invention has a main body 711. At one end of the main body 711, a protrusion 712 for coupling with the female terminal is extended. The other end of the main body 711 has an arc-shaped pinching portion 713 that provides a slot 714 in the arc surface. Both sides 715 and 716 of the sandwiching part 713 have a symmetrical arc-shaped curvature.

In the design in which both sides 715 and 716 of the sandwiching portion 713 of the male terminal 71 in the present embodiment exhibit a symmetrical arc-shaped curve, both sides 715 and 716 of the sandwiching portion 713 are used by using a relatively simple and inexpensive processing machine. The inner conductor 811 of the coaxial cable 81 can be securely sandwiched by smoothly bending it oppositely. In the process in which the inner conductor 811 is sandwiched between the sandwiching portions 713, a part of the inner conductor corresponding to the slot 714 is deformed by force and falls into the slot 714. When the coaxial cable 81 receives a tension that causes the detachment from the holding part 713, the deformed portion of the inner conductor 811 that has fallen into the slot 714 has a resistance, so that the inner conductor 811 is relatively rarely released from the clamping part 713. .

And a slot 831. The difference is that it has high portions 832 and 833, low portions 834 and 835, and inclined portions 836 and 837 respectively corresponding to the ends of both sides of the sandwiching portion 83.

It is advantageous in that it can be bent, the contact ends on both sides can be brought into perfect contact, the distorted contact state is relatively rare, and the inner conductor 811 of the coaxial cable receives the maximum clamping force. It is firmly coupled to the clamping part 83.
