However, as coaxial cables connectors become lighter, thinner, and smaller, the coaxial cables are becoming thinner, and the pitch and depth (axial dimensions of the coaxial cable) of the connecting portion with the outer conductor are reduced. There was a tendency for productivity to decrease as well. Further, it is difficult to fix the elastic coaxial cable, and there is a fear that the electrical and mechanical connection reliability is lowered. For example, when connecting by crimping, it is necessary to crimp the coaxial cables one by one, and the crimping part must be enlarged. Also, in the case of soldering, a large space is required for soldering, and the jacket and jacket of the coaxial cable may shrink and melt due to heat, which may cause variations in dimensions and performance. It tends to be short-circuited between conductors or coaxial cables adjacent to each other. Furthermore, in the case of connecting by pressure welding (IDC: Insulation Displacement Contact), if the coaxial cable becomes a thin wire, it tends to bend, so that the connection tends to be insufficient. In particular, when the outer conductor is a braid, it is difficult to obtain stable conduction because the braid easily escapes during pressure welding. There is also a problem that the inner conductor is easily cut by the pressure of the pressure contact.

In order to solve the above problems, a coaxial cable connector of the present invention is a coaxial cable connector that is electrically connected to a plurality of coaxial cables arranged in a row at a predetermined pitch, and corresponds to the predetermined pitch. A first contact member comprising a plurality of first pressing terminals that are respectively disposed and sandwich the exposed outer conductor of the coaxial cable;
A second contact member that is arranged corresponding to a predetermined pitch and includes a plurality of second pressing terminals that sandwich a portion of the exposed outer conductor of the coaxial cable that is different from a portion that the first pressing terminal sandwiches. It is characterized by providing.

The connector preferably includes a shell portion including a first contact member and an insulator portion including a second contact member. By fitting the shell portion to the insulator portion, a plurality of coaxial cables are provided. The outer conductor can be sandwiched between the first pressing terminal and the second pressing terminal.

Preferably, the first pressing terminal has a substantially U shape with the insulator portion side open, and the second pressing terminal preferably has a substantially U shape with the shell portion side open, and the shell portion is fitted to the insulator portion. Thus, the outer conductors of the plurality of coaxial cables may be sandwiched between the first pressing terminal and the second pressing terminal from opposite directions along the fitting direction.

From the exposed external conductor, it is preferable to form two conduction paths through the first pressing terminal or the second pressing terminal.

A coaxial cable connector according to the present invention includes a receptacle connector connected to a signal processing device, a plug connector electrically connected to a plurality of coaxial cables arranged in a row at a predetermined pitch, and fitted into the receptacle connector. A connector for a coaxial cable, wherein the plug connector is arranged corresponding to a predetermined pitch, and includes a first contact member including a plurality of first pressing terminals that sandwich the exposed outer conductor of the coaxial cable, and A second contact member that is arranged corresponding to a predetermined pitch and includes a plurality of second pressing terminals that sandwich a portion of the exposed outer conductor of the coaxial cable that is different from a portion that the first pressing terminal sandwiches. It is characterized by providing.

According to the present invention, since the exposed outer conductor of the coaxial cable is sandwiched between the two pressing terminals, the mechanical reliability is improved and the electrical connection is ensured even if the coaxial cable is thinned. The connector can be downsized. Further, since there are two conduction paths, high electrical reliability can be obtained. Furthermore, according to this structure, even if the pitch of a coaxial cable becomes small and it becomes multipolar, it can be electrically connected easily and, thereby, productivity can be improved. Further, since the signal line is surrounded by the ground line, the shielding effect can be improved.

The second shell portion 81 has a U-shape of the second pressing terminal 83 supported by the insulator portion 41 by arranging the first support portion 84 at a predetermined position corresponding to the elastic contact portion 39 of the second ground member 36. The second pressing terminal 83 corresponds to the plurality of outer conductors 103 of the coaxial cable 100 held by the plug connector 40 and comes into contact with the cover 61 and the first shell 71. Be placed. 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.

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 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 due to its elasticity. As a result, not only the second shell portion 81 and the second ground member 36 are electrically connected, but also the external conductor 103 is further press-fitted into the second pressing terminal 83, so that the second shell portion 81 and the external The electrical connection with the conductor 103 becomes more reliable. 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.

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.

Although the present invention has been described with reference to the above embodiment, the present invention is not limited to the above embodiment, and can be improved or changed within the scope of the purpose of the improvement or the idea of the present invention.
