  The present invention relates to an electrical connector and a method for manufacturing the same.

In the case of inspecting the surface mount type semiconductor package and the circuit board, or when connecting the surface mount type semiconductor package and the circuit board, a pressure contact type connector is used.
As such a connector, for example, a plurality of sheets of wiring obtained by aligning the directions of a plurality of conductive lines and maintaining insulation from each other are laminated with the direction of the conductive lines fixed, and a plurality of sheets of the obtained laminate are obtained. However, the conductive lines are aligned and integrated into a step shape at a certain angle to form a block body, and the obtained block body is bonded to the slicing substrate surface, parallel to the substrate surface and the conductive wire. There is known a pressure contact type connector (see, for example, Patent Document 1) which is cut by two parallel surfaces crossing the surface. In addition, the insulating member having the through-hole, and the through-hole fitted in a state protruding from at least one of the front and back surfaces of the insulating member, the connection terminal of the first device and the connection terminal of the second device are electrically connected A conductive member to be connected. The conductive member includes an insulating elastic body and a metal wire. The conductive member is embedded in the height direction of the elastic body so that the metal wire penetrates the conductive member. An electrical connector (see, for example, Patent Document 2) having a gap in at least a part between a conductive member and a through hole in a state of being fitted in the through hole is known.

[Electric connector]
FIG. 1 is a cross-sectional view showing a schematic configuration of the electrical connector of the present embodiment.
As shown in FIG. 1, the electrical connector 10 of this embodiment includes an insulating member 20 and a conductive member 30.
The electrical connector 10 is disposed between a connection terminal of a first device (not shown) and a connection terminal of a second device (not shown), and electrically connects them. Examples of the device include a semiconductor package and a circuit board.

The insulating member 20 is a laminated body including an elastic body 40 and a resin sheet-like member 50 laminated on one main surface (upper surface in FIG. 1) 40 a of the elastic body 40.
The insulating member 20 has a through hole 21 penetrating in the thickness direction. That is, the through hole 21 penetrates the elastic body 40 and the sheet-like member 50 in the thickness direction. The through hole 21 penetrates the insulating member 20 obliquely with respect to the thickness direction. Furthermore, the through hole 21 of the insulating member 20 includes a through hole 41 that penetrates the elastic body 40 obliquely with respect to the thickness direction, and a through hole 51 that penetrates the sheet-like member 50 obliquely with respect to the thickness direction. Become.

The angle of the through hole 21 with respect to the thickness direction of the insulating member 20, that is, the angle at which the line perpendicular to the one main surface 40 a of the elastic body 40 intersects the through hole 21 (angle θ ₁ shown in FIG. ₁ ) is 10 ° to 85. It is preferable to be °. The angle of the through hole 21 with respect to the thickness direction of the insulating member 20 is the arrangement of the connection terminals of two devices that are electrically connected by the electrical connector 10 (specifically, the conductive member 30 fitted in the through hole 21). It adjusts suitably according to.

Examples of the shape of the through hole 21 include a circle, an ellipse, a triangle, a square, a rectangle, and a pentagon or more polygon.

  The hole diameter of the through hole 21 is not particularly limited, and is appropriately adjusted according to the diameter (outer diameter) of the conductive member 30 fitted into the through hole 21. The hole diameter of the through hole 21 is preferably 0.05 mm to 0.3 mm, for example.

  Moreover, the hole diameter of the through-hole 21 is the back surface (the other main surface 40b side of the elastic body 40) of the insulating member 20 rather than the hole diameter of the surface (surface of the elastic body 40 on the one main surface 40a side) 20a. It is preferable to reduce the hole diameter of 20b. Thereby, since the conductive member 30 fitted into the through hole 21 is firmly fitted into the through hole 21 at least on the back surface 20b side of the insulating member 20, the conductive member 30 is moved from the back surface 20b side of the insulating member 20. It can be prevented from falling off.

The thickness of the insulating member 20 is preferably 0.05 mm to 2.0 mm, for example. The thickness of the elastic body 40 is preferably 0.03 mm to 1.0 mm, for example. The thickness of the sheet-like member 50 is preferably 0.01 mm to 1.0 mm, for example.

  In the electrical connector 10 of this embodiment, the elasticity required for the conductive member 30 means that the electrical connector 10 is disposed between a connection terminal of a first device (not shown) and a connection terminal of a second device (not shown). In order to maintain the state where both ends (one end 30a, the other end 30b) of the conductive member 30 and the connection terminals of the two devices are electrically connected to each other, the conductive member for each connection terminal The pressing force at both ends of 30 is sufficiently obtained, and the connection terminal is not damaged by the pressing force.

  The conductive member 30 is fitted in the through hole 21 of the insulating member 20. In the state where the conductive member 30 is fitted in the through hole 21, one end 30a thereof protrudes from the surface 20a of the insulating member 20 (the surface on the one main surface 40a side of the elastic body 40), and the other end. The portion 30b protrudes from the back surface 20b of the insulating member 20 (the surface on the other main surface 40b side of the elastic body 40) 20b. Thereby, the electrically-conductive member 30 is arrange | positioned so that the insulating member 20 may be penetrated diagonally with respect to the thickness direction.

Metal wire), plate-like members, and the like. When the electrical connector 10 is used for connecting devices for high-frequency current applications, the conductive member 30 is preferably a hollow body having a large surface area. This is because the high-frequency current flows through the surface layer of the device, so that the surface area of the conductive member 30 is preferably large.

  The material of the elastic body 40 is not particularly limited as long as it is elastic when the elastic body 40 is used. For example, acrylonitrile-butadiene rubber, silicone rubber, chloroprene rubber, ethylene-chloroprene rubber, ethylene-propylene-diene rubber , Synthetic rubbers such as styrene-butadiene rubber, fluorine rubber, butadiene rubber, isoprene rubber, and urethane rubber. Among these, silicone rubber is preferable because it is highly elastic and excellent in heat resistance.

The material of the sheet-like member 50 is not particularly limited as long as the sheet-like member 50 has heat resistance and dimensional stability. For example, polyimide (PI), epoxy resin, polyethylene terephthalate (PET), Polybutylene terephthalate (PBT), polyvinyl chloride, polystyrene, polyacrylonitrile, polyethylene, polypropylene, acrylic, polybutadiene, polyphenylene ether (PPE), polyphenylene sulfide (PPS), polyether ether ketone (PEEK), liquid crystal polymer (LCP), Polyamideimide (PAI), polyetherimide (PEI), polyethersulfone (PES), etc. are mentioned.

  According to the electrical connector 10 of the present embodiment, the insulating member 20 includes the elastic body 40 and the resin sheet-like member 50 laminated on one main surface 40a of the elastic body 40. Even if the thickness is reduced, the conductive member 30 can be firmly held by the insulating member 20. Thereby, the length of the conductive member 30 disposed so as to penetrate the insulating member 20 can be shortened. As a result, the electrical connector 10 can be suitably used for connecting devices for high-frequency current applications. Further, since the conductive member 30 held by the insulating member 20 has appropriate elasticity, an excessive force is not applied from the conductive member 30 to the connection terminal, and the connection terminal can be prevented from being damaged. Moreover, since the insulating member 20 is comprised from the elastic body 40 and the sheet-like member 50, it is excellent in heat resistance and dimensional stability rather than what consists only of an elastic body, and can connect devices stably. it can.

  In the present embodiment, the case where the insulating member 20 is the elastic body 40 and the sheet-like member 50 laminated on one main surface 40a thereof is exemplified, but the present embodiment is not limited to this.
