It was easy to move and was easy to be electrically unstable. Furthermore, when the so-called inclined fitting, which is fitted in the inclined direction from the original fitting direction, is made, the spring is excessively displaced, and when the misalignment is made, the spring may be bent. .

In order to solve the above problem, the connector of the present invention is a connector having a first connector and a second connector fitted with the first connector, wherein the first connector and the second connector are electrically conductive members for electrically connecting with each other. Each of the first connector and the second connector, the fitting of the first connector and the second connector is released when the first connector and the second connector are fitted. It is characterized in that the elastic contact portion is pressed in the direction of the.

It is preferable that the said elastic contact part is in contact with the conductive member with which the other of a 1st connector and a said 2nd connector is equipped.

A plurality of coaxial cables arranged in a column shape at a predetermined pitch may be electrically connected to the connector.

The elastic contact portion may press the conductive member electrically connected to the coaxial cable, among the conductive members of the first connector or the second connector, to be in contact with the exposed outer conductor of the coaxial cable.

Preferably, the elastic contact portion is disposed on the side from which the coaxial cable extends.

The elastic contact portion and the coaxial cable may be disposed in the order of the coaxial cable and the elastic contact portion in the fitting direction between the first connector and the second connector.

The conductive member may be made of metal.

The conductive member may have a conductive path formed by a MID (Molded Interconnect Device). The conductive member may be a shell portion for ground connection.

In addition, if the elastic contact part 39 and the coaxial cable 100 are arrange | positioned in order of the coaxial cable 100 and the elastic contact part 39 in the fitting direction of the receptacle connector 20 and the plug connector 40, it is mentioned above. It can also be arranged differently from one layout.

By arranging in this way, for example, when the receptacle connector 20 is mounted on a substrate (not instructed) such as a device, since the elastic contact portion 39 is disposed between the substrate and the coaxial cable 100, the substrate is placed on the substrate. Unnecessary space can be effectively utilized, contributing to miniaturization of equipment and the like.

The fitting of the receptacle connector 20 and the plug connector 40 is performed by first elastically contacting the shell spring 80 of the first shell portion 71 with the plate-shaped base 32 of the first ground member 31. The plug connector 40 may be inserted in the receptacle connector 20 so that the elastic contact portion 39 abuts against the second shell portion 81, whereby the workability of the fitting can be improved.

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. Further, since the outer conductor 103 of the coaxial cable 100 is pressed into the second shell portion 81 and the outer conductor 103 is covered with the first pressing terminal 74, the coaxial cable Even if the pitch of (100) becomes small and it becomes multipolar, it becomes easy to electrically connect the some coaxial cable 100, and can improve productivity by this.

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 of the contacts 76 and the receptacle contacts 26, and enclosing them, the EMI (Electro Magnetic Interference) effect can be improved. Furthermore, the elasticity of the elastic contact portion 39 of the second ground member 36 causes the first support portion 84 of the second shell portion 81 to be upward (direction of releasing the fit of the plug connector 40 ( The outer conductor 103 can be pushed into the first pressing terminal 74 and into the second pressing terminal 83, so that the first shell portion 71 and the second shell Since the electrical connection between the shell portion 81 and the outer conductor 103 can be ensured, the EMI effect can be stabilized.

Instead of the above-mentioned first shell portion 71 or the second shell portion 81, a conductive path is formed (MID) by plating on the resin when the insulating portion 41 is molded or after molding. The elastic contact portion 39 may be brought into contact with the conductive path. By forming the conductive paths on the surface of the resin in this way, the signal line can be wrapped to provide EMI protection.

Although this invention was demonstrated with reference to the said Example, this invention is not limited to the said Example, It is possible to improve or change within the range of the objective of improvement and the idea of this invention.

According to the present invention, since the receptacle connector has an elastic contact portion which presses the plug connector in the direction in which the fitting is released (release direction) when the plug connector is inserted into the receptacle connector, It can absorb the rattling of the coaxial cable connector, so that even if an external pressure is applied to the coaxial cable connector or a rattling or tilting occurs in the fitted state, it absorbs this to stabilize the conduction of the coaxial cable and the shell portion. You can. Therefore, since the ground connection by the shell part and the coaxial cable can be ensured, the EMI countermeasure by covering a signal line by this ground connection can be implemented stably.

Further, since the spring of the shell portion on the plug connector side is elastically brought into contact with the receptacle connector, the plug connector can be inserted into the receptacle connector so that the elastic contact portion and the plug connector come into contact with each other, thereby improving the workability of the fitting. Moreover, since the outer conductor is pushed into the first pressing terminal and the second pressing terminal by the elastic contact portion, the electrical connection between the first shell portion and the second shell portion and the outer conductor becomes more secure.
