DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a method for wiring an electronic component such as an LSI having a plurality of contacts on one surface.
The contact of the electronic component can be connected to the contact of the other party to be connected at one time, and even if the contact of the other party is disconnected from this electronic component, the connection state of the other contact can be maintained. The present invention relates to a connection device that can be easily connected again when connected to the above electronic component again.

[0002]

2. Description of the Related Art Conventionally, there is no device for connecting a mating contact to an electronic component having a plurality of contacts at one time. For example, a coaxial cable connector is used for an LSI having a plurality of pads (contacts) on one surface. In the past, when connecting
The only option is to connect a plurality of coaxial cable connectors directly to the LSI one by one.

[0003]

In the above example, if it becomes necessary to remove the coaxial cable connector from the LSI after wiring, a plurality of coaxial connectors must be removed from the LSI one by one. Further, the plurality of coaxial cable connectors removed from the LSI cannot maintain the wiring state to the pads of the LSI. Therefore, when the plurality of coaxial cable connectors are connected to the LSI again, the first wiring is performed. I have to start over again
This wiring work was very troublesome. As described above, according to the related art, when connecting a contact on the other side to an electronic component having a plurality of contacts, it is impossible to connect these contacts at one time. It takes time and effort to remove the contact on the other side from the electronic component, and when the contact on the other side is connected to the electronic component again, the connection operation has to be performed again from the beginning.

[0004] Therefore, an object of the present invention is to make it possible to connect a plurality of contacts on a mating side to an electronic component having a plurality of contacts at a time, and to connect the mating contacts connected to this electronic component to each other. It is another object of the present invention to provide a connection device which can be disconnected at a time, and can be easily reconnected when connecting a mating contact to an electronic component again.

An external contact 55 is slidably disposed in the center line direction of the outer cylinder 51 on the outer periphery of the outer cylinder 51 and is electrically connected thereto.
Cage, one end portion projects into LSI4 side than the outer tube 51. The distal end of the outer cylinder 51 is bent outward at a right angle, and the external contact 55 is locked at this portion. A spring 5 is provided around the outer cylinder 51.
6 are arranged. The spring 56 urges the external contact 55 toward the LSI 4. The upper part of the coaxial cable connector 5 forms a catch 58 having a circumferential groove 57. The locking projection 24 of the fixing plate 20 is
The coaxial cable / connector 5 is held by the second holding member 2 by fitting. As long as the coaxial cable / connector 5 held by the second holding member 2 is not pulled out from the hole 23, its wiring state to the LSI 4 is held by the second holding member 2. The center contact 52 and the external contact 55 of the coaxial cable connector 5 described above
The signal 40 of the LSI 4 and the contact of the ground 41 are opposite contacts, that is, the second contact.

Next, a procedure for connecting an LSI to a coaxial cable by the connection device of this embodiment will be described.

First, as shown in FIG. 5, the second holding member 2 is detached from the first holding member 1, and each of the holes formed in the fixing plate 20 of the second holding member 2 is set. 23
Then, the coaxial cable connectors 5 respectively connected to the coaxial cable 6 are inserted in correspondence with the signal 40 and the ground 41 of the LSI 4. As a result, each coaxial cable connector 5 is held by the second holding member 2 in a state where the retaining portion 58 is engaged with the lock projection 24 and corresponds to the signal 40 and the ground 41 of the LSI 4.

Next, as shown in FIG. 3, the tube 31 of the pressing member 3 is previously placed in the storage chamber 15 of the first holding member 1 with the second holding member 2 removed. Furthermore,

Since the foamed resin injected into the tube 31 is hardened after being expanded, the connection between the LSI 4 and the coaxial cable connector 5 is maintained in a stable state.

On the other hand, if it becomes necessary to disconnect the coaxial cable / connector 5 from the LSI 4 due to a failure of the LSI 4, etc.
First, the bottom plate 11 of the first holding unit 1 is removed from the lower frame 10, and the tube 31 is taken out of the storage chamber 15. As a result, the LSI 4 moves downward together with the push plate 32, and
SI4 signal 40 and ground 41, coaxial cable
Center contact 52 of connector 5 and external contact 5
5 is disconnected. Next, the second holding member 2 is slid in a direction parallel to one plane, the second holding member 2 is detached from the first holding member 1, and an appropriate treatment such as repair or replacement is performed on the LSI 4. Apply. At this time, the wiring state of the coaxial cable connector 5 with respect to the LSI 4 is maintained by the second holding member 2. When the LSI 4 is connected to the coaxial cable connector 5 again, the storage room 1 of the lower frame 10 is connected.
A new tube 31 is provided in 5, and the bottom plate 11 is fixed to the lower surface of the lower frame 10. Thereafter, the second holding member 2 is slid and fitted to the first holding member 1. As a result, the wiring is restored as before. When the foamed resin is injected into the tube 31 again, the signal 40 and the ground 41 of the LSI 4 and the coaxial cable connector 5
Are connected to the center contact 52 and the external contact 55.
