However, as the height of the coaxial cable connector progresses, it becomes impossible to secure a sufficient spring length (spring length) in the fitting direction, and this causes an insufficient amount of spring displacement. It was. For this reason, deviation may occur within the clearance required for fitting the receptacle connector and the plug connector. However, depending on the deviation, the displacement of the shell spring cannot follow and the contact pressure changes greatly. In some cases, the contact resistance and other electrical performances were affected.
In particular, in the case of a cable connector such as a coaxial cable, an external force or the like accompanying the operation of the cable is transmitted to the connector via the cable, so that the fitted connector is likely to be displaced, and in particular, the side holding the cable is detached. It was easy to move in the unplugging direction and easily became electrically unstable.
Furthermore, when so-called oblique fitting is performed in which the fitting is performed from a direction inclined from the original fitting direction, the spring may be excessively displaced or the spring may be buckled if misalignment fitting is performed. there were.

In order to solve the above-described problems, a connector of the present invention is a connector including a first connector and a second connector that is fitted to the first connector, and the first connector and the second connector are electrically connected to each other. Each of the first connector and the second connector is connected with the other one of the first connector and the second connector when the first connector and the second connector are fitted to each other. An elastic contact portion for biasing in the direction of releasing the fitting is provided.

It is preferable that the elastic contact portion is in contact with a conducting member provided in the other of the first connector and the second connector.

A plurality of coaxial cables arranged in a line at a predetermined pitch can be electrically connected to the connector.

The said elastic contact part is good to urge the conductive member electrically connected with a coaxial cable among the conductive members of a 1st connector or a 2nd connector so that it may contact | abut to the exposed external conductor of a coaxial cable.

The elastic contact portion is preferably arranged on the side where the coaxial cable extends.

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

The conducting member can be made of metal.

The conduction member can include a conduction path formed by MID. The conductive member may be a shell portion for ground connection.

According to the present invention, since the receptacle connector includes the elastic contact portion that urges the plug connector in a direction to release the fitting (removal direction) when the plug connector is inserted into the receptacle connector, the height of the receptacle connector is reduced. Even in the connected connector, it is possible to absorb the rattling of the coaxial cable connector after mating, and this causes the rattling and tilting in the mated state due to external force applied to the coaxial cable connector. Even if this is absorbed, conduction between the coaxial cable and the shell portion can be stabilized. Therefore, since the ground connection between the shell portion and the coaxial cable can be secured, it is possible to stably realize the EMI countermeasure by surrounding the signal line with the ground connection.

In addition, the plug connector can be fitted into the receptacle connector so that the spring of the shell portion on the plug connector side is brought into elastic contact with the receptacle connector and then the elastic contact portion is brought into contact with the plug connector. Can be improved. Furthermore, since the outer conductor is pressed into the first pressing terminal and the second pressing terminal due to the elasticity of the elastic contact portion, the electrical connection between the first shell portion and the second shell portion and the outer conductor is further improved. It will be certain.

Thus, by providing the 1st support part 84 and the 2nd support part 85 in the 2nd shell part 81, while being able to improve the rigidity of the 2nd shell part 81, the 2nd shell part 81 with respect to the insulator part 41 is improved. Holding power can be improved. Note that the material and manufacturing method of the second shell portion 81 are the same as those of the receptacle contact 26, and thus detailed description thereof is omitted.

The cover portion 61 shown in FIG. 5B is an injection molded product of synthetic resin that is an insulating member, and has a long plate shape. On the lower surface 66 at one end portion in the width direction, the same number of introduction recesses 62 as the coaxial cable 100 are provided at the pitch corresponding to the pitch of the coaxial cable 100 toward the upper surface 67 side. The upper surface 67 is provided with terminal insertion holes 64 penetrating from the upper surface 67 to the lower surface 66 at a pitch corresponding to the introduction recess 62 on the inner side in the width direction than the position corresponding to the introduction recess 62. In addition, fitting protrusions 65 are provided at both ends in the longitudinal direction of the lower surface 66 so as to protrude downward. The cover portion 61 is held by the insulator portion 41 by fitting the fitting convex portion 65 into the fitting concave portion 45 of the insulator portion 41.

A first shell portion (first contact member) 71 shown in FIG. 5C is a substantially long plate-like metal member, and includes a contact tongue portion 72, a contact tongue portion 73, a first pressing terminal 74, and the like. , A locking portion 75 and a shell spring (FIG. 1, FIG. 4B) 80. In addition, since the material and manufacturing method which comprise the 1st shell part 71 are the same as that of the receptacle contact 26, detailed description is abbreviate | omitted.

The contact tongue 72 and the contact tongue 73 are bent so as to extend in parallel to each other downward (downward in FIG. 5C) from both longitudinal ends of the first shell portion 71. The contact tongue portion 72 and the contact tongue portion 73 are fitted into the insertion hole portion 46 of the insulator portion 41 when the first shell portion 71 is coupled to the insulator portion 41 via the cover portion 61. It extends downward from the lower surface of the. The contact tongue 72 is formed with a through hole 72a that is formed in the thickness direction. When the plug connector 40 is inserted into the receptacle connector 20, the projections 38 a and 38 b of the second ground member 36 are engaged with the through holes 72 a of the two contact tongues 72, respectively. The second ground member 36 is electrically connected. At this time, the contact tongue 72 abuts against the fixed end portions 34b and 35b of the first ground member 31 due to the spring property of the portions where the projections 38a and 38b are provided, and the first shell portion 71 and the first ground member 31 are in contact with each other. Electrically connected. The first shell portion 71, the cover portion 61, and the insulator portion 41 are thus locked, and the lock strength is set to be greater than the total reaction force of the elastic contact portion 39.

The first pressing terminal 74 and the locking portion 75 have a plurality of substantially U-shapes opened downward at a pitch corresponding to the arrangement bit of the coaxial cable 100 on one end face in the width direction of the first shell portion 71. Are provided in a row. The locking portion 75 is disposed at a position corresponding to the terminal insertion hole 44. The first pressing terminal 74 penetrates through the terminal insertion hole 64 of the cover portion 61 when the first shell portion 71 is coupled to the insulator portion 41 via the cover portion 61, and the tip thereof is a terminal insertion hole of the insulator portion 41. 44. The width of the space formed by the U shape of the first pressing terminal 74 is preferably smaller than the diameter of the outer conductor 103. When the width is reduced, the outer conductor 103 is press-fitted into the first pressing terminal 74, so that the outer conductor 103 is reliably held. On the other hand, from the viewpoint of easy insertion of the outer conductor 103 into the first pressing terminal 74, the U-shaped width of the first pressing terminal 74 is preferably equal to or larger than the diameter of the outer conductor 103. .

The shell spring 80 is provided on the other end surface in the width direction of the first shell portion 71 so as to extend downward at a constant interval. The shell spring 80 has a curved surface 80 a that comes into contact with the side surface of the plate-like base portion 32 when the plug connector 40 is fitted into the receptacle connector 20.

As shown in FIG. 7, the coaxial cable 100 is arranged in concentric layers from the axis side in the order of an inner conductor 101, an insulator 102, a braided outer conductor 103, and a jacket (outer jacket) 104, which are one conductor. The cables are arranged at a predetermined pitch (for example, 0.4 mm pitch) by joining the jackets 104 to each other. In this embodiment, the inner conductor 101 is a single conducting wire, but a coaxial cable in which a plurality of conducting wires are accommodated in the insulator 102 may be used. Also, a type of outer conductor that is not a braid can be used.

The coaxial cable 100 has an inner conductor 101, an insulator 102, an outer conductor 103, and a jacket 104 at a predetermined length according to the shape of the coaxial cable connector 10 by a strip process or a laser process, for example. It is processed to be exposed at the position. Specifically, at the tip of the coaxial cable 100, the inner conductor 101 is exposed for a length corresponding to the signal connection portion 78 of the plug contact 76 integrated with the insulator portion 41, and the insulator 102 is subsequently exposed. Then, the outer conductor 103 is exposed at a position corresponding to the second pressing terminal 83 on the insulator portion 41 through a portion where the jacket 104 is left without being exposed. The external conductor 103 is exposed to a position where the first pressing terminal 74 can be contacted when the receptacle connector 20 is inserted into the plug connector 40. Here, since the portion where the jacket 104 is left is provided on the tip side of the exposed portion of the outer conductor 103, the broken portion of the outer conductor 103 is not exposed, so that a part of the braid is cut and dropped. This can reduce the risk of work and prevent deterioration of workability and performance. Further, when the protrusion portion 47 that positions and clamps the insulator 102 is formed on the insulator portion 41, workability is improved and separation between the inner conductor 101 and the outer conductor 103 is ensured, that is, a short circuit is further prevented. It becomes possible.

The plug connector 40 according to this embodiment is assembled as follows.
First, a plurality of coaxial cables 100 coupled to each other are gripped by a dedicated jig, for example, and the exposed distal end side of the external conductor 103 (exposed internal conductor 101 side) is sandwiched inside the second pressing terminal 83. The inner conductor 101 at the tip is brought into contact with the signal connection portion 78, respectively. Thereby, 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 hot plate or a laser, whereby the coaxial cable 100 and the plug contact 76 are electrically connected. The electrical connection between the plug contact 76 and the internal conductor 101 can be performed by press-fitting or spring contact in addition to soldering.

Next, the cover portion 61 is coupled to the insulator portion 41 by fitting the fitting convex portion 65 into the fitting concave portion 45. When coupled, the jacket 104 behind the exposed outer conductor 103 is accommodated and held in the introduction recess 62, and the terminal insertion hole 44 of the insulator portion 41 is disposed below the terminal insertion hole 64 of the cover portion 61. Subsequently, the first pressing terminal 74 is inserted into the terminal insertion hole 64, and the contact tongue portion 72 and the contact tongue portion 73 are inserted into the insertion hole portion 46, so that the first shell portion 71 is attached to the cover portion 61. It couple | bonds with the insulator part 41 via. At this time, the first pressing terminal 74 passes through the terminal insertion hole 64 and exposes the external conductor 103 at a position on the exposed rear end side of the external conductor 103, that is, at a position different from the position where the second pressing terminal 83 is sandwiched. It is inserted into the terminal insertion hole 44 so as to be sandwiched from above. As a result, the outer conductor 103, the first shell portion 71, and the second shell portion 81 are electrically connected. Further, the locking portion is press-fitted into the terminal insertion hole 44 and locked.

As shown in FIG. 1, the plug connector 40 is fitted into the receptacle connector 20 so that the connecting portion 77 of the plug contact 76 is press-fitted into a space sandwiched between the bent portion 28 of the receptacle contact 26 and the inner wall of the insertion groove 22a. Is done. Thereby, the plug contact 76 connected to the inner conductor 101 and the receptacle contact 26 are electrically connected.

On the other hand, the two contact tongues 72 are press-fitted between the fixed end 34b and the protrusion 38a and between the fixed end 35b and the protrusion 38b, respectively, and the curved surface 80a of the shell spring 80 is a plate-like shape of the first ground member 31. In order to contact the outer surface 32c of the base portion 32 (FIG. 1), the first shell portion 71, the first ground member 31, and the second ground member 36 are electrically connected.

Further, the elastic contact portion 39 of the second ground member 36 abuts so as to push up the first support portion 84 of the second shell portion 81 upward (in a direction to release the fitting of the plug connector 40) due to its elasticity. ing. As described above, the lock strength of the first shell portion 71, the cover portion 61, and the insulator portion 41 is set to be larger than the sum of the reaction forces of the elastic contact portion 39, so that the second shell portion 81 and Not only is the second ground member 36 electrically connected, but the outer conductor 103 can be further press-fitted into the second pressing terminal 83, and electrical connection between the second shell portion 81 and the outer conductor 103 can be achieved. It will be more certain. 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 external conductor 103 are electrically connected and grounded. With such a configuration, even if the coaxial cable connector 10 is reduced in height, the rattling of the coaxial cable connector 10 after the receptacle connector 20 and the plug connector 40 are fitted can be absorbed. Even if an external force is applied to the coaxial cable connector 10 to cause rattling or tilting in the fitted state, it can be absorbed, and the coaxial cable 100, the first shell portion 71, the second shell portion 81, Can be stabilized.

It is also possible to provide the elastic contact portion 39 on the plug connector 40 and provide a contact surface with which the elastic contact portion contacts the first shell member 71 or the second shell member 81 of the receptacle connector 20. Further, the elastic contact portion 39 and the coaxial cable 100 are arranged in a manner other than the above-described arrangement as long as the coaxial cable 100 and the elastic contact portion 39 are arranged in this order in the fitting direction of the receptacle connector 20 and the plug connector 40. Can do.
With this arrangement, for example, when the receptacle connector 20 is mounted on a board (not indicated) such as a device, the elastic contact portion 39 is arranged between the board and the coaxial cable 100. The above useless space can be effectively utilized, and it can contribute to downsizing of devices and the like.

When the receptacle connector 20 and the plug connector 40 are fitted, the shell spring 80 of the first shell portion 71 is first brought into elastic contact with the plate-like base portion 32 of the first ground member 31, and then the elastic contact portion 39 is brought into contact with the second shell portion 81. The plug connector 40 can be fitted into the receptacle connector 20 so as to be brought into contact with the receptacle connector 20, thereby improving the fitting workability.

Further, the outer conductor 103 can be sandwiched between the first pressing terminal 74 and the second pressing terminal 83 from above and below (from the opposite direction), and pressure can be applied so as to compress the exposed outer conductor 103. Thereby, since a load can be uniformly applied to the outer conductor 103, the force for holding the coaxial cable 100 can be increased and the mechanical characteristics can be improved. Furthermore, even if the coaxial cable 100 is thinned, it can be reliably connected, and the coaxial cable connector 10 can be reduced in size. Furthermore, with this sandwiching configuration, even if the coaxial cable 100 is vibrated and pulled, the connection can be maintained, so that the mechanical reliability can be improved. Further, since the outer conductor 103 of the coaxial cable 100 is press-fitted into the second shell portion 81 and the first pressing terminal 74 is covered with the outer conductor 103, the pitch of the coaxial cable 100 is reduced, and the multipolarization is achieved. Even if this is done, it is possible to easily connect a plurality of coaxial cables 100, thereby improving productivity.

Further, the conduction path from the external 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 terminal 83 of the second shell portion 81 to the second ground. Since there are two paths to the member 36, a conduction path can be reliably ensured, thereby improving the reliability of the ground connection. Further, the first ground member 31 and the second ground member 36 are electrically connected to each other, thereby connecting the two conductive paths from the outer conductor 103 to each other. In this closed space, the inner conductor 101 and the plug contact are connected. By arranging signal line lines 76 and receptacle contacts 26 and surrounding them, the EMI (electromagnetic interference) effect can be improved. Further, the elasticity of the elastic contact portion 39 of the second ground member 36 pushes up the first support portion 84 of the second shell portion 81 upward (in the direction of releasing the fitting of the plug connector 40 (withdrawing direction)). Therefore, the outer conductor 103 can be press-fitted into the first pressing terminal 74 and the second pressing terminal 83, and the electrical connection between the first shell portion 71 and the second shell portion 81 and the outer conductor 103 can be achieved. Since reliable connection is ensured, the EMI effect can be stabilized.

Further, instead of the first shell portion 71 and the second shell portion 81 described above, when the insulator portion 41 is resin-molded or after molding, a conductive path is formed by plating on the resin (MID (Molded Interconnect Device)). The elastic contact portion 39 can be brought into contact with the conductive path. Thus, by forming the conductive path on the surface of the resin, it is possible to surround the signal line and take measures against EMI.
