Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention particularly relates to a connection structure for electrically connecting a lead of a flat package and a contact of a measurement socket.

(Prior Art) Conventionally, as shown in FIG. 5, the above-mentioned connection structure has had many protruding leads on the side surface of the package 1, or the ends of the leads 2 are placed at positions corresponding to the leads 2 on the upper surface of the socket 3. On the other hand, a contact 4 is inserted into the socket 3 so that its upper end 4a protrudes into the recess 3a of the socket 3, and a package holding plate 5 is inserted from above the socket.
The convex portions 5a were inserted into each of the concave portions 3a.

Further, as shown in FIG. 6, one recess 3/a is formed on the upper surface of the socket 3' to accommodate a large number of leads 2,
The package holding plate 5' was also provided with a protruding portion 5'a corresponding to the recessed portion 3/a, and the same procedure as described above was carried out.

Then, as shown in FIG. 7, the lead 2 and the contact 4 are connected to each other.
The electrical connection was made to the upper end 4a of the holder.

As shown in the figure, the contactor 4 was configured to extend horizontally and have a springy upper end 4a.

(Problems to be Solved by the Invention) However, since the contactor 4 is usually formed by punching, as shown in FIGS. 8(a) to (c),
The upper surface of the upper end 4a is rounded and cannot be formed flat, and for this reason, the lead 2 slips on this upper surface, and in the case of the conventional example shown in FIG. 5 above, as shown in FIG. In the case of the conventional example shown in FIG. 6, the leads 2 may be twisted in the horizontal direction as shown in FIG. 10.

For this reason, there is a problem in that not only problems may arise in terms of appearance and use, but also it may become difficult to take out the package 1 from the socket 3.

In view of the above, the present invention has been made with the object of providing a device that solves these problems.

[Structure of the invention]

(Means for Solving the Problems) In order to achieve the above object, the present invention interposes conductive rubber between the leads of the package and the contacts of the socket, and applies pressure to the conductive rubber to bring them together. It is designed to conduct electricity.

(Function) By interposing the conductive rubber between the package lead and the socket contact, the lead is prevented from sliding on the top surface of the contact, and in this state, the conductive rubber By applying pressure to the rubber, conduction is established between the lead and the contact through the conductive rubber.

(Embodiment) FIGS. 1 and 2 show an embodiment of the present invention, in which a large number of protrusions are formed on the side surface of the package 1, and the ends of the door 2 are
It is inserted into a recess 3a formed on the upper surface of the socket 3 at a position corresponding to the lead 2. On the other hand, a contact 4 is provided inside the socket 3 with its upper end 4a protruding into the recess 3a of the socket 3.

A conductive rubber 6 that becomes conductive when pressure is applied is interposed between each lead 2 and the upper end 4a of the contact 4, and the conductive rubber 6 is pressed from above by a package presser. It is pressed by the convex portion 5a of the plate 5, and due to this pressure, the conductive rubber 6 becomes conductive, and the lead 2 and the upper end 4a of the contact 4 are electrically connected.

As shown in FIG. 2, this conduction is achieved by first inserting conductive rubber 6 into the recesses 3a of the socket 3 through which the contacts 4 are inserted, and then fitting the leads 2 onto the upper surface of the conductive rubber 6. ,
This can be easily done by attaching the package holding plate 5.

3 and 4 show other embodiments of the present invention,
A recess 3/a capable of accommodating a large number of boards 2 is formed on the upper surface of the socket 3', and a recess 3/a is formed on the upper surface of the socket 3'.
Also, a protruding portion 5'a corresponding to this recessed portion 3/a is provided protrudingly. A piece of conductive rubber 6' is interposed between each lead 2 and the contact 4, and the conductive rubber 6' is interposed between each lead 2 and the contact 4 as in the above embodiment. The upper end 4a is electrically connected to the upper end 4a.

In addition, in the case of this embodiment, it is not necessary to configure the upper end 4a of the contactor 4 to have spring properties as in the conventional example.

〔Effect of the invention〕

Since the present invention has the above-described configuration, the leads do not slip on the top surface of the contact, and therefore, the leads are hardly twisted or bent in the horizontal direction, and the leads are Not only is the electrical connection of the contact more stable, but the contact area of the lead is also wider, further enhancing this stability effect. Furthermore, there is an effect that the degree of freedom in connecting the leads is increased.
