照）。 Conventionally, rod-shaped insulating rubber elastic materials have been used to connect various electrical and electronic components that have multiple connection terminals arranged in parallel, such as between printed circuit boards or flat cable wires to printed circuit boards. An elastomer having anisotropic conductivity, which has a structure in which a large number of conductive linear bodies are aligned in the height direction along the longitudinal direction of the body, and the end surfaces of the linear bodies are exposed on the upper and lower pressure contact surfaces. A method is known in which an electrical connection is obtained by using an elastic connector and clamping the elastic connector between objects to be connected (see, for example, Japanese Patent Laid-Open No. 147991/1983).

に欠けるものであつた。 However, the elastic connector described above generally bulges and deforms in a direction perpendicular to the direction in which the pressing force is applied as pressing force is applied, and at the same time, the conductive linear body inside the elastic connector is buckled, stretched, or cut. This often causes problems such as increased circuit resistance and poor connections. In addition, when the conductive linear body in the connector is composed of metal wire, metal fiber, metal ribbon, carbon fiber, etc., due to the composite elastic effect of the rubber elastic body and the above linear body, this In addition to requiring a considerable compressive load to press and clamp the connector uniformly between the objects to be connected, this type of connector also tends to permanently deform due to this compression. There is a disadvantage in that poor conductivity tends to occur when used repeatedly or when vibration is applied to a press-contact state under a constant load, and in any case, the reliability of the electrical connection is lacking.

A pressing force is applied to the connector 2 by pressing a pressure welding jig 7 having two protruding portions 6, 6 through a flexible lead pin 5a of an electric/electronic component such as an LSI.

A pressing force is applied by sandwiching an elastic connector 2 having two rows of conductive linear bodies 4, and the protruding portion 6 is located between the two rows of linear bodies. There is.

る。 As is clear from FIGS. 2 to 4, the present invention is directed to a pressure welding jig 7 that is brought into contact with the terminal surface side of the circuit board 1 or the back surface of the circuit board 1 as shown in the drawings.
At least one protrusion element 6 is provided on the connector, and a pressing force is applied to the connector in the presence of this protrusion element 6, and this protrusion element 6 is arranged along the arrangement direction of the connection terminals. It is necessary to position the conductive linear bodies 4 disposed on the pressure welding surface so as to avoid the parts that are involved in conduction. It is possible to reduce the buckling load as much as possible while increasing the compression margin of the rubber elastic body 3 on both sides of the rows of the linear bodies 4 and/or between the rows of the linear bodies 4. As a result, large buckling deformation of the conductive linear body 4 can be avoided, the pressing load required to obtain a reliable electrical connection state can be reduced, and furthermore, the conductive linear body 4 can be permanently Since the amount of deformation can be reduced,
When the pressing load is removed, it is unlikely to remain largely deformed, or the exposed end surface of the linear body 4 will not be depressed below the pressing surface of the connector, and it will be able to withstand repeated pressing loads well. It is.

られる。 In addition, in FIGS. 2 to 4, a conductive linear body 4 is shown.
Regarding the connectors 2, the connectors 2 are arranged linearly along the longitudinal direction, but the linear bodies 4 do not need to be arranged in this way, and can be arranged randomly without the need for alignment. The conductive linear bodies may be arranged and oriented, for example, as disclosed in Japanese Patent Application Laid-Open No. 52-65892, and may be uniformly dispersed over the entire pressing surface. However, in the case of such a connector, if the conductive linear body 4 is in contact with the protrusion element 6, when this connector is pressed, the linear conductor 4 in contact with the protrusion element 6 will be seated. Since there is a risk of bending and deformation, it is necessary to position the protruding strip elements 6 avoiding rows of linear conductors 4 that are involved in conduction. Even if they are in contact, buckling of the conductive linear body is limited to areas that are not involved in electrical connection, so that a good electrical contact state can be obtained substantially for the reasons described above.

きるのである。 FIG. 5 shows an example of a testing device for a flat package type electronic component 8 to which the present invention is applied. The base 9 has a recess 12 for storing the electronic component 8 and an elastic connector 2.
A recess 13 is provided for accommodating a plurality of electrodes 5 each connected to the connector 2.
is provided. On the other hand, on the lower surface of the pressing member 11, pressure contact portions 7 each having two protruding portions 6 are provided corresponding to the recesses 13 of the base 9. In this test device, the electronic component 8 is placed on the base 9.
The press member 11 is rotated to press the pressure contact part 7 against the lead pin 5a of the electronic component, and is fixed with the locking tool 14 between the plurality of electrodes 5. Various tests and inspections are performed on the elastic connector 2 in this device, and since a pressing force is applied under the condition shown in Fig. 2, the elastic connector 2 in this device is subject to repeated application of pressing force. Therefore, it is possible to maintain its function.

価値はきわめて大きい。 As explained above, the method for connecting circuit boards, etc. according to the present invention is to connect a large number of conductive wires between a plurality of connection terminals that are arranged parallel to each other on circuit boards that are arranged opposite to each other, or electrical and electronic components. When an elastomer connector held through the body array is held and pressed, the conductive linear body array that participates in conduction is applied to the circuit board or on a pressure welding jig that is in contact with the circuit board. This is done through a protrusion element installed at a position that avoids the risk of damage.This allows a reliable electrical connection to be achieved even under a slight pressure load, and avoids repeated pressure clamping and vibration. Its practical value is extremely great because it can fully demonstrate its functions even when used under such conditions.
