Description

  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, an insulating member having a through hole is joined to the through hole in a state protruding from at least one of the front and back surfaces of the insulating member, and the connection terminal of the first device and the connection terminal of the second device are electrically connected. A conductive member, and the conductive member includes an insulating elastic body and a metal wire, embedded in the height direction of the elastic body so that the metal wire penetrates, and 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 where the hole is joined is known.

  The thickness of the elastic body 20 is not particularly limited, and is appropriately adjusted according to the elasticity required for the conductive member 30 joined to the through hole 21. The thickness of the elastic body 20 is preferably 0.03 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 joined to the through hole 21 of the elastic body 20. Thereby, the electrically-conductive member 30 is arrange | positioned so that the elastic body 20 may be penetrated diagonally with respect to the thickness direction.

Moreover, it is preferable that the conductive member 30 protrudes from at least one of the one main surface 20a and the other main surface 20b of the elastic body 20 in a state where the conductive member 30 is joined to the through hole 21, and the conductive member 30 21, one end 30 a protrudes from one main surface 20 a of the elastic body 20, and the other end 30 b protrudes from the other main surface 20 b of the elastic body 20. preferable. In the state where the conductive member 30 is joined to the through-hole 21, the outermost surface (end surface) of one end portion 30a exists on the same plane as at least one main surface 20a of the elastic body 20, and the other end It is only necessary that the outermost surface (end surface) of the end portion 30b exists on the same plane as the other main surface 20b of the elastic body 20.

  The material of the elastic body 20 is not particularly limited as long as the elastic body 20 has elasticity. 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. Moreover, as a material of the elastic body 20, what has the tolerance with respect to the wet etching mentioned later is preferable.

  The conductive member 30 is not particularly limited as long as it can electrically connect the connection terminals of the two devices. Examples of the conductive member 30 include metals such as gold, silver, copper, iron, nickel, cobalt, titanium, beryllium, zinc, and aluminum, or alloys thereof, and metal wires and hollow bodies (cylindrical shapes) made of composites thereof. 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.

Therefore, as shown in FIG. 2A, the first conduction region 41 and the non-conduction region 42 in the vicinity thereof are deformed (bent) in the thickness direction of the elastic body 20 with a smaller force. Thereby, when connecting the connection terminal of the device and the conductive member 30 of the first conduction region 41, 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. . In the electrical connector 10 of the present embodiment, the non-conductive region 42 including the hollow through hole 21 is easily deformed (easily bent) in the thickness direction of the elastic body 20. As a result, the entire electrical connector 10 can be deformed (bent) in the thickness direction with a smaller force.

  In the present embodiment, as shown in FIG. 1, a resin sheet-like member 50 may be laminated on one main surface 20 a of the elastic body 20. Although FIG. 1 illustrates the case where the sheet-like member 50 is laminated on the entire surface of the one main surface 20 a of the elastic body 20, the sheet-like member 50 only needs to be laminated at least in the non-conduction region 42. Also, the sheet-like member 50 may be laminated on the other main surface 20b of the elastic body 20 similarly to the one main surface 20a. When the sheet-like member 50 is laminated on the first conduction region 41, it is preferable that the conductive member 30 is provided so that one end 30 a and the other end 30 b protrude from the sheet-like member 50.

Among these, polyimide (PI), polyphenylene sulfide (PPS), polyether ether ketone (PEEK), and liquid crystal polymer (LCP) are preferable from the viewpoint of excellent heat resistance and dimensional stability.
In addition, as the sheet-like member 50, the nonwoven fabric which consists of these resin may be sufficient.

  If the resin-made sheet-like member 50 is laminated on one main surface 20a of the elastic body 20, the laminated body composed of the elastic body 20 and the sheet-like member 50 is more heat resistant than the case of the elastic body 20 alone. In addition, it is excellent in dimensional stability and can connect devices stably. Further, by laminating the sheet-like member 50 on one main surface 20a and the other main surface 20b of the elastic body 20, heat resistance and dimensional stability on the one main surface 20a and the other main surface 20b of the elastic body 20 are obtained. Are the same. As a result, the laminate composed of the elastic body 20 and the sheet-like member 50 is more excellent in heat resistance, dimensional stability, thickness reduction, and durability.

In the present embodiment, the elastic body 20 may have a notch that surrounds the first conduction region 41 and is formed in the thickness direction.
The angle of the notch with respect to the thickness direction of the elastic body 20, that is, the angle at which the notch intersects with a line perpendicular to one main surface 20 a of the elastic body 20 is not particularly limited, but the thickness direction of the elastic body 20 of the through hole 21 is not limited. Is preferably equal to the angle to. That is, the angle of the notch with respect to the thickness direction of the elastic body 20 is preferably 10 ° to 85 °. The angle of the cutout with respect to the thickness direction of the elastic body 20 is appropriately adjusted according to the arrangement of the connection terminals of the two devices electrically connected by the electrical connector 10.

  The shape of the notch may be a tongue shape such as a U-shape in addition to a loop shape in plan view. If the electrical connector 10 provided with the notches having these shapes is used, the elastic body 20 is deformed with a low load without applying an excessive load. Therefore, the position of the electrical connector 10 with respect to the device can be adjusted, and the durability of the electrical connector 10 is improved.

  The width of the notch, that is, the interval between the first conduction region 41 and the non-conduction region 42 is not particularly limited, and is appropriately adjusted according to the arrangement of connection terminals of two devices electrically connected by the electrical connector 10. Is done.

  The depth of the notch, that is, the length from one main surface 20a of the elastic body 20 to the other main surface 20b is not particularly limited, and the connection terminals of the two devices that are electrically connected by the electric connector 10 It adjusts suitably according to arrangement | positioning etc. of this.

  If the elastic body 20 surrounds the first conduction region 41 and has a notch formed in the thickness direction, the electrical connector 10 can be deformed according to the shape of the device. As a result, the electrical connector 10 can stably connect two devices with a low load.

Hereinafter, with reference to FIG. 11A to FIG. 11E, a method for manufacturing the electrical connector of the present embodiment will be described.
FIG. 11A to FIG. 11E are cross-sectional views illustrating an outline of the method for manufacturing the electrical connector of the present embodiment. 11 (a) to 11 (e), the same reference numerals are given to the same components as those of the electrical connector manufacturing method according to the first embodiment shown in FIGS. 3 (a) to 3 (d). A duplicate description will be omitted.

  For example, in the same manner as the method described in Japanese Patent No. 2787032, a composite body 60 is produced in which the conductive member 30 is joined to a large number of through holes 21 that penetrate the elastic body 20 in the thickness direction (FIG. 11). (A) Reference, step A).

  Next, as shown in FIG. 11A, masking layers 1000 and 1000 are formed on one main surface 60a and the other main surface 60b of the composite 60 (step B).

  Next, as shown in FIG. 11B, a part of the masking layer 1000 is removed from one main surface 60a of the composite 60 (step C).

  Next, as shown in FIG. 11 (c), the conductive member 30 is removed at the portion where the masking layer 1000 is removed from the composite 60, and the main body 20 a of the elastic body 20 and the other main surface 20 are formed on the composite 60. On the surface 20b, a non-conductive region 42 including the through hole 21 to which the conductive member 30 is not joined is formed (step D).

  Next, as shown in FIG. 11 (d), the remaining portion of the masking layer 1000 in the composite 60 is removed, and the composite 60 has a non-conductive region on one main surface 20 a and the other main surface 20 b of the elastic body 20. A plurality of first conduction regions 41 including the through holes 21 to which the conductive members 30 are joined are formed with the 42 interposed therebetween (step E).

  Next, as shown in FIG. 11 (e), a part of the first conduction region 41 and the non-conduction region 42 are removed in the thickness direction from the one main surface 60 a side of the composite body 60. Then, the second conductive region 43 is formed that protrudes in the thickness direction of the composite body from the first conductive region 41 and the non-conductive region 42 (step G).

  In the process G, as a method of removing a part of the first conduction region 41 and the non-conduction region 42, for example, a mechanical processing method such as laser etching or cutting is used.

  The electrical connector 400 shown in FIG. 10 is obtained by the above process A to process G.

  According to the method for manufacturing an electrical connector of the present embodiment, in step G, the second conductive region 43 that protrudes in the thickness direction of the composite from the non-conductive region 42 is formed on one main surface 60a side of the composite 60. Therefore, even if there is a step in the connection terminal of the device, it is possible to manufacture the electrical connector 400 that can stably maintain the electrical connection state between the conductive member 30 and the connection terminal.

  In the present embodiment, in step G, on the one main surface 60a side of the composite 60, the first conductive region 41 is closer to the thickness direction of the composite 60 than the first conductive region 41 and the non-conductive region 42. Although the case where the protruding 2nd conduction | electrical_connection area | region 43 is formed was illustrated, this invention is not limited to this. In step G, on the one main surface 60a side and the other main surface 60b side of the composite 60, the first conductive region 41 is closer to the thickness direction of the composite 60 than the first conductive region 41 and the non-conductive region 42 are. You may have the 2nd conduction | electrical_connection area | region 43 which protrudes.

  In the electrical connector manufacturing method of this embodiment, after the step E of forming the first conduction region 41, the one end 30a and the other end 30b of the conductive member 30 are connected to one main portion of the elastic body 20. You may have the process made to protrude from the surface 20a and the other main surface 20b.

  Furthermore, in the manufacturing method of the electrical connector of this embodiment, it may have a process of plating one end 30a and the other end 30b of the conductive member 30.

An excessive force is not applied from 80, and the connection terminals can be prevented from being damaged. Further, since the conductive member 80 is made of an elastically deformable material, the angle of the conductive member 80 with respect to the thickness direction of the elastic body 20, that is, the angle at which the conductive member 80 intersects a line perpendicular to the one main surface 20 a of the elastic body 20. Even if the angle is 85 ° or more, excessive force is not applied from the conductive member 80 to the connection terminal when the connection terminal of the device and the conductive member 80 of the first conduction region 41 are connected, and the connection terminal is damaged. Can be prevented.

  Also in this embodiment, a resin sheet-like member may be laminated on one main surface 20 a of the elastic body 20. Further, a sheet-like member may be laminated on the other main surface 20b of the elastic body 20 similarly to the one main surface 20a.
