The present invention relates to a coaxial cable connector suitable for high speed transmission of communication equipment, transmission equipment, measuring equipment, and other signal processing equipment.

Conventional coaxial cable connectors have been provided with a receptacle connector connected to a signal processing device and a plug connector to which a plurality of coaxial cables are connected and fitted into the receptacle connector. In this coaxial connector, the electrical connection and the mechanical connection to the outer conductor and the connecting piece (e.g., ground contact) are made by, for example, crimping and soldering (e.g., Japan Patent Publication No. 2004-179150).

It became small, and it was difficult to reduce the size by the conventional connection method, and there existed a tendency for productivity to fall. In addition, it is difficult to fix the coaxial cable having elasticity, resulting in a decrease in electrical and mechanical connection reliability. For example, when connecting by crimping, it is necessary to crimp the coaxial cables one by one, and the crimping portion cannot be large. In addition, in the case of soldering, a large space for soldering is required, and the size and performance of the jacket of the coaxial cable may shrink due to heat, resulting in irregular dimensions and performance. Coaxial cables adjacent to each other tend to be shorted. In the case of connecting by IDC (Insulation Displacement Contact), the coaxial cable is easily bent when the wire becomes thin, so that the connection is likely to be insufficient. In particular, in the case where the outer conductor is braided, braiding tends to come out during press welding, so that stable conduction is difficult to be obtained. In addition, there is a problem that the inner conductor is easily cut by the pressure of the pressure welding.

In order to solve the above problem, the coaxial cable connector of the present invention is a coaxial cable connector which is electrically connected to a plurality of coaxial cables arranged in a row shape at a predetermined pitch, and is arranged in correspondence with a predetermined pitch.

Preferably, the connector includes a shell portion having a first contact member and an insulation portion having a second contact member, and by fitting the shell portion to the insulation portion, the outer conductor of the plurality of coaxial cables is connected to the first pressing terminal and The second press terminal can be pinched respectively.

It is preferable that the said 1st press terminal is formed in the substantially U shape which opened the insulation part side, and the 2nd press terminal consists of the substantially U shape which opened the shell part side, and it fits in a shell part by fitting a shell part, The outer conductors of the two coaxial cables may be respectively sandwiched by the first pressing terminal and the second pressing terminal from opposite directions along the fitting direction.

The exposed external conductor may be provided with two conductive paths passing through the first pressing terminal or the second pressing terminal.

In this embodiment, the inner conductor 101 is a single conductor, but a plurality of conductors may be a coaxial cable housed in the insulator 102. It is also possible to use external conductors of a type other than braiding.

The coaxial cable 100 has an inner conductor 101, an insulator 102, an outer conductor 103, and a jacket 104 for the coaxial cable at the front end thereof, for example, by strip processing or laser processing. It is processed so that it may expose by predetermined length and predetermined position according to the shape of the connector 10. FIG. Specifically, at the front end of the coaxial cable 100, the inner conductor 101 is exposed by the length corresponding to the signal connection portion 78 of the plug contact 76 integrated with the insulation portion 41, and then the insulator 102 ) Is exposed, and the outer conductor 103 is exposed at a position corresponding to the second pressing terminal 83 on the insulating portion 41 via the portion that leaves the jacket 104 without being exposed. When the receptacle connector 20 is inserted into the plug connector 40, this outer conductor 103 is exposed to the position which the 1st press terminal 74 can come into contact with. Here, by providing a portion in which the jacket 104 is left in front of the exposed portion of the outer conductor 103, since the fracture portion of the outer conductor 103 is not exposed, a part of the braid is cut off and the possibility of falling down is reduced. This can prevent deterioration of workability and performance. In addition, by forming the projections 47 for positioning and sandwiching the insulator 102 on the insulator portion 41, the workability is improved and the separation between the inner conductor 101 and the outer conductor 103 is ensured, i.e. Therefore, the short circuit can be further prevented.

Plug connector 40 according to the present embodiment is assembled as follows.

First, a plurality of coaxial cables 100 coupled to each other are gripped by, for example, a dedicated jig, so that the front end side (exposed inner conductor 101 side) of the exposed outer conductor 103 is the second pressing terminal. Each of them is pressed so as to be sandwiched inside the 83, and the inner conductor 101 of the front end is brought into contact with the signal connecting portion 78, respectively. As a result, the outer conductor 103 and the second shell portion 81 are electrically connected. The inner conductor 101 is soldered to the signal connection portion 78 using, for example, a hotplate and a laser, whereby the coaxial cable 100 and the plug contact 76 are electrically connected. On the other hand, the electrical connection between the plug contact 76 and the inner conductor 101 may be made by pressing or spring contact, in addition to soldering.

Subsequently, the cover portion 61 is coupled to the insulating portion 41 by inserting the fitting convex portion 65 into the fitting concave portion 45. When combined, the jacket 104 behind the exposed outer conductor 103 is received and held in the inlet recess 62, and the lower portion of the insulator 41 is provided below the terminal insertion hole 64 of the cover 61. The terminal insertion hole 44 is disposed. Subsequently, the first pressing terminal 74 is inserted into the terminal insertion hole 64, and the contact tongue 72 and the contact tongue 73 are inserted into the insertion hole 46, and the first shell portion ( 71 is coupled to the insulating portion 41 through the cover portion (61). At this time, the first pressing terminal 74 passes through the terminal insertion hole 64 and is positioned at the rear end of the exposed outer conductor 103, that is, at the position where the second pressing terminal 83 is held. In another position, the outer conductor 103 is inserted into the terminal insertion hole 44 so as to be sandwiched from above. Thereby, the outer conductor 103, the 1st shell part 71, and the 2nd shell part 81 are electrically connected. Moreover, the engaging portion is pressed into the terminal insertion hole 44 to be engaged.

As shown in FIG. 1, the plug connector 40 presses the connection part 77 of the plug contact 76 into the space clamped by the bending part 28 of the receptacle contact 26 and the inner wall of the insertion groove 22a. It fits in the receptacle connector 20. As a result, the plug contact 76 and the receptacle contact 26 connected to the inner conductor 101 are electrically connected.

On the other hand, the two contact tongues 72 are pressed in between the fixed end 34b and the projection 38a and between the fixed end 35b and the projection 38b, respectively, and the curved surface 80a of the shell spring 80 is pressed. Since it abuts on the outer side surface 32c of the plate-shaped base 32 of the first ground member 31 (FIG. 1), the first shell portion 71, the first ground member 31, and the second ground member 36. ) Is electrically connected.

Moreover, the elastic contact part 39 of the 2nd ground member 36 is contact | abutted so that the 1st support part 84 of the 2nd shell part 81 may be pushed upward by the elasticity. As a result, not only the second shell portion 81 and the second ground member 36 are electrically connected to each other, but also the external conductor 103 is pushed further into the second pressing terminal 83, so that the second shell portion 81 ) And the external conductor 103 are more securely connected. As a result, the first ground member 31, the second ground member 36, the first shell portion 71, the second shell portion 81, and the outer conductor 103 are electrically connected and grounded.

In addition, the outer conductor 103 is sandwiched between the upper and lower sides (from the opposite direction) by the first pressing terminal 74 and the second pressing terminal 83, and the pressure is applied to compress the exposed outer conductor 103. Can be. As a result, since the external conductor 103 can be uniformly loaded, the force holding the coaxial cable 100 can be increased to improve mechanical properties. Furthermore, even if the coaxial cable 100 is thin, it can be reliably connected, and can cope with the miniaturization of the coaxial cable connector 10. In addition, the structure can be maintained even if the coaxial cable 100 is vibrated or towed by this sandwiching configuration, thereby improving mechanical reliability. In addition, since the outer conductor 103 of the coaxial cable 100 is pressed into the second shell portion 81 and the first press terminal 74 is covered with the outer conductor 103, the coaxial cable 100 Even if the pitch is small and multipolarized, the plurality of coaxial cables 100 can be electrically connected easily, whereby the productivity can be improved.

Furthermore, a path from which the conductive path from the outer conductor 103 passes through the first pressing terminal 74 of the first shell portion 71 to the first ground member 31 and the second pressing portion of the second shell portion 81. Since there are two kinds of paths from the terminal 83 to the second ground member 36, the conductive path can be securely ensured, whereby the reliability of the ground connection can be improved. Furthermore, by electrically connecting the first ground member 31 and the second ground member 36 to each other, the two conductive paths from the outer conductor 103 are connected to each other, so that the inner conductor 101 and the plug are in this closed space. By arranging signal line lines formed from the contacts 76 and the receptacle contacts 26, the electromagnetic wave effects can be enhanced by wrapping them.
