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
It is only possible to connect one pin contact to the built-in socket contact, and it is not possible to obtain an electrical connection between pin contacts.

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

[Means for solving problems]

According to the present invention, a device for electrically connecting different pin contacts to each other includes two insulating housings facing each other in a first direction, and a conductive solenoid disposed between the two housings. The socket contact has two socket portions facing the two housings one-to-one, and a flexible elastic portion connecting the two socket portions, An electrical connection device characterized in that the two housings are relatively movable in a second direction perpendicular to the first direction, and each housing has a pin guide hole facing the socket portion. is obtained.

〔Example〕

1 to 8 show an embodiment of an electrical connection device according to the present invention. The electrical connection device (hereinafter referred to as "connector") 1 of the illustrated embodiment is
It 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.
Combined upper and lower housings 6, 7
A space is formed inside. A large number of socket contacts 8 are regularly arranged in three rows in the space.

Socket contact 8 is pin contact 4, 5
It has a pair of socket portions 9 for receiving. The pair of socket parts 9 are integrally connected to both ends of the flexible elastic part 10 so as to be point symmetrical. Each of the socket portions 9 is formed into an encircling shape, specifically a rectangular tube shape, and pin contacts 4 and 5 are provided on the inner surface thereof.
There are contact points at two different positions in the direction of insertion. These contact points are also connected to the socket part 9
are on opposite sides when viewed from the central axis.

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 9 of the socket contacts 8 on a one-to-one basis. The connector 1 also includes a frame 12 assembled to the outer peripheral sides of the upper and lower housings 6 and 7. Inside the frame 12, the upper housing 6 is movable in the direction of arrow 13 shown in FIGS. 2 and 5 or in the opposite direction (ie, in the lateral direction). Further, a drive cam 14 inserted through a side hole in the frame 12 is opposed to one end surface of the upper housing 6, and can be rotated by a lever 15 connected thereto. Thus lever 15
When the drive cam 14 is rotated by the upper housing 6, the upper housing 6 moves in the direction of the arrow 13, that is, in the lateral direction, in accordance with the cam surface of the drive cam 14.

Now, as shown in FIGS. 5 to 7, the connector 1
When the axes of the pin guide hole 11 of the pin guide hole 11 of the socket contact 8 and the socket part 9 of the socket contact 8 are substantially aligned with each other, each pin contact 4, 5 is inserted as shown in FIG.
When inserted into each pin guide hole 11, they can be inserted into the socket part 9 with very little force. The size of the socket portion 9 is the same as that of each pin contact 4,
Needless to say, the dimensions are such that it can be fitted with a gap between the two parts.

Next, when the drive cam 14 is rotated by the lever 15, the upper housing 6 is moved in the direction of the arrow 13. At this time, the pin contacts 4 are also carried in the same direction, and each pin contact 4, 5 is moved into the socket part 9. come into contact with. When the upper housing 6 is further advanced in the direction of the arrow 13, the pin contacts 4 and 5 are strongly engaged with the socket portion 9, causing the flexible elastic portion 10 of the socket contactor 8 to be deformed. Therefore, due to the elastic restoring force of the flexible elastic portion 10, 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 9 is inclined with respect to the axis of the pin contacts 4 and 5, and the restoring force of the flexible elastic part 10 acts to return the socket part 9 to its original position. As a result, each pin contact 4, 5 contacts each socket portion 9 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. 8, 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 9. Therefore, the contact pressure between the pin contacts 4, 5 and the socket portion 9 can be increased, so that reliable contact can be obtained.

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 can electrically connect different pin contacts, and the force required for inserting the pin contacts is small. A sufficiently large contact pressure can be maintained between the socket contact and the socket contact.
