Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an electrical connection device, and more particularly to a device for electrically connecting different pin contacts.

[Conventional technology]

Conventionally, it includes a socket contact formed by providing a socket part with a fitting hole at the tip of a flexible elastic piece,
A pin contact with a smaller diameter is inserted into the fitting hole of the socket part, and then the pin contact is moved laterally to bend the flexible elastic piece and come into strong contact with the socket part. There are devices for establishing an electrical connection between a socket contact and a pin contact (for example, Japanese Patent Laid-Open Nos. 58-106774 and 1982-105986). This has the advantage that the force required to insert the pin contact into the fitting hole of the socket portion is extremely small, and the contact pressure between the contacts can be increased.

[Problem that the invention attempts to solve]

However, the device disclosed in the above publication is only capable of connecting one pin contact to a built-in socket contact, and cannot obtain electrical connection between pin contacts.

Therefore, the purpose of the present invention is to provide an electrical connection between different pin contacts, requiring less force to insert the pin contacts, and increasing the contact pressure between the pin contacts and the socket contacts. Our goal is to provide electrical connection devices that can

In addition to the above objects, another object of the present invention is to provide an electrical connection device in which contact between a pin contact and a socket contact is made elastic.

[Means for solving the problem] According to the present invention, in a device for electrically connecting different pin contacts to each other, two insulating housings facing each other in a first direction, a conductive socket contact disposed between the two housings, and the socket contact includes two socket parts facing the two housings on a one-to-one basis, a connecting part connecting the two socket parts, and a conductive socket contact arranged between the two housings. The two housings are relatively movable in a second direction perpendicular to the first direction, and each has a pin guide hole facing the socket portion. The electrical connection device is characterized in that the socket portion has a contact spring piece on at least one of both side surfaces in the second direction that contacts the pin contact.

〔Example〕

1 to 10 show an embodiment of an electrical connection device according to the present invention. Electrical connection device (hereinafter referred to as "connector") 1 of the illustrated embodiment
is used to mount a first circuit board 2 made of an LSI package onto a second circuit board 3 made of a printed board. The first and second circuit boards 2 and 3 each hold a large number of conductive pin contacts 4 and 5 fixedly arranged in a regular manner.

The connector 1 includes an upper housing 6 and a lower housing 7 that face each other in the vertical direction. These housings 6, 7 are made of an insulator. A space is formed inside the combined upper and lower housings 6, 7. In the space, a large number of socket contacts 8 are regularly arranged in three rows.

Socket contact 8 is pin contact 4, 5
It has a pair of socket portions 82 for receiving. As shown in FIG. 4, the socket contact 8 is formed into a generally cylindrical shape by bending a press-cut plate. The socket contact 8 thus manufactured has a connecting portion 81 in the center on its central axis, and socket portions 82 on both sides along the central axis. One side of the socket portion 82 is constituted by a contact spring piece 83. The other socket part 82
The opposite side of the socket contact 8 when viewed from the central axis is constituted by a contact spring piece 83. Each of these contact spring pieces 83 extends from the connecting portion 81 to the socket portion 82.

Further, in the portion between the connecting portion 81 and the socket portion 82, side holes 84 are formed in the side surfaces facing the respective contact spring pieces 83. These side holes 8
4 is located at a position corresponding to the tips of the pin contacts 4 and 5 inserted into the socket portion 82.

Upper and lower housings 6, 7 of connector 1
A large number of pin guide holes 11 are formed in each of the pin contacts 4 and 5 to receive the pin contacts 4 and 5, respectively. These pin guide holes 11 are formed at positions facing the socket portions 82 of the socket contacts 8 on a one-to-one basis. The connector 1 also includes a frame 9 assembled to the outer peripheral sides of the upper and lower housings 6 and 7. Inside this frame body 9, the upper housing 6 is movable in the direction of arrow 10 shown in FIGS. 2 and 6 or in the opposite direction (ie, in the lateral direction). Furthermore, a drive cam 12 inserted through a side hole in the frame 9 is opposed to one end surface of the upper housing 6, and can be rotated by a lever 13 connected thereto. Thus, when the drive cam 12 is rotated by the lever 13, the upper housing 6 is moved in the direction of the arrow 10, that is, in the lateral direction, in accordance with the cam surface of the drive cam 12.

Now, as shown in FIGS. 6 to 8, the connector 1
When the axes of the pin guide hole 11 of the pin guide hole 11 and the socket part 82 of the socket contact 8 are substantially aligned with each other, each pin contact 4, as shown in FIG.
5 into each pin guide hole 11, they can be inserted into the socket part 82 with very little force. It goes without saying that the size of the socket portion 82 is made such that it can fit into each pin contact 4, 5 with a gap. Next, lever 1
When the drive cam 12 is rotated by 3, the upper housing 6 moves in the direction of the arrow 10, and at this time, the pin contacts 4 are also carried in the same direction, and each pin contact 4, 5 comes into contact with the socket part 9. . When the upper housing 6 is further fed in the direction of the arrow 10,
The pin contacts 4 and 5 are strongly engaged with the socket portion 82, causing the contact spring piece 83 of the socket contactor 8 to be deformed. Therefore, the contact spring piece 8
Due to the elastic restoring force of 3, the corresponding pin contacts 4 and 5 are both reliably connected to the socket contact 8.

By the way, at the time of connection, the axis of the socket part 82 is inclined with respect to the axis of the pin contacts 4 and 5, and the restoring force of the contact spring piece 83 acts to return the socket part 82 to its original position. As a result, each pin contact 4, 5 contacts each socket portion 82 at two points. These contact points in each socket portion 9 are at different positions in the axial direction of each pin contact 4, 5, and are on opposite sides of each other when viewed from the axial center. That is, as shown in FIG. 9, equal forces P and F are applied in opposite directions to the contact points between the pin contacts 4 and 5 and the socket portion 82. Therefore, the contact pressure between the pin contacts 4, 5 and the socket portion 82 can be increased, so that reliable contact can be obtained.

In the above embodiment, the contact spring piece 83 is provided on the side receiving the force F among the two contact points of each socket part 82, but instead,
For example, as shown in Figure 10, the side receiving the force of P,
That is, a contact spring piece 83' is attached to a portion corresponding to the side hole 84.
may be provided. Also, both contact spring pieces 83, 8
3' may be provided at the same time. Furthermore, the socket contacts 8 shown in FIGS. 3 and 10 may be used in combination at the upper and lower portions of the socket contacts 8, respectively.

It is preferable that a return spring (not shown) be interposed between the upper housing 6 and the frame 12 so that the upper housing 6 can be easily returned to its original position if necessary.

[Effect of idea]

As explained above using the embodiments, the electrical connection device of the present invention enables electrical connection between different pin contacts, requires less force for inserting the pin contacts, and connects the pin contacts with each other electrically. A sufficiently large contact pressure can be maintained between the butt contact and the butt contact.
