However, in such sockets, the output terminals protrude from the bottom of the socket, making it difficult to wire the tester, and once connected, it is extremely difficult to change the arrangement. The inventor of the present invention has discovered that there is a problem.

[Purpose of the invention]

An object of the present invention is to provide a socket that can simplify wiring work to an external connector.

The above and other objects and novel features of the present invention will become apparent from the description of this specification and the accompanying drawings.

[Summary of the invention]

A brief summary of the invention disclosed in this application, which is related to clothing, is as follows.

That is, by arranging the output terminal of the socket on the side surface, wiring work to an external connector such as a tester can be easily performed.

〔Example〕

FIG. 1 is a perspective view showing a socket which is an embodiment of the present invention, and FIG. 2 is an enlarged partial sectional view thereof.

In this embodiment, this socket 4 is used for connecting an axial ICI in which a large number of bins 3 are aligned and protruded from the bottom surface of the package 2 perpendicularly to the bottom surface of the package 2 to a tester (not shown). It is constructed as a thing. This socket 4 consists of an input part 5 and an output part 6,
The input s5 includes an input section main body 7 and a presser plate 8 made of an insulating material such as synthetic resin. The input section main body 7 is formed into a substantially square board shape, and as shown in FIG. 2, a large number of insertion holes 9 are bored in the upper surface thereof so as to correspond to the arrangement of the bins 3 in the axial ICI. There is.

An input terminal member 10 made of a conductive leaf spring or the like is installed in the insertion hole 9, and a bottle 11 is attached to the bottom of the insertion hole 9.
is electrically connected to the input terminal member 10 at its upper end, and is provided such that its lower end protrudes from the lower surface of the input section main body 7 perpendicularly to the lower surface of the input section main body 7. The holding plate 8 is slidably attached to the upper surface VC of the input section main body 7, and is rotated by operating a lever 13 through an eccentric shaft 12 inserted through one end of the input section main body 7. It is designed to be moved. A large number of holding holes 14 are arranged and bored in the holding plate 8 so as to correspond to the insertion holes 9. The output section main body 15 is made of an insulating material such as ceramic or synthetic resin and is almost similar to the input section 5. The main body 15 of the output section has a large number of through holes 16 arranged to correspond to the bins 11 of the input section 5. Each inner lead 17 is connected to each of the through holes 16 so as to be electrically independent from each other, and the other end of this . In order to ensure mutual insulation between the many inner leads 17, the output section main body 15 is formed into a laminated structure as necessary. A large number of output terminal members 18 are electrically and mechanically connected to each inch lead 17 and protrude from the side surface of the output section main body 15.
There is a lead wire (not shown) for a tester, etc. that performs sorting inspection and inspection.
are connected as appropriate. This work of connecting the lead wires is easy to perform because the output terminal member 18 protrudes from the side surface of the socket 4 in all directions.

A surface ground layer 19 is attached to the lower surface of the output section main body 15, and a chamfer 9 20 is formed in the surface ground layer 19 and the through hole 16 portion of the output section main body 15.

The lower surface of the input section main body 7 of the output section main body 15 is aligned with the surface opposite to the surface on which the surface ground layer 19 is formed, and at this time, each bottle 11 is inserted into each through hole 16. . In this state, the through hole 16
A solder material is poured into the hole, and a solder layer 21 is formed between the inner periphery of the through hole 16 and the outer periphery of the bottle 11. This solder layer 21 connects the p1 output section main body 15 and the input section main body 7.
are mechanically connected and integrated, and electrically connected to the output terminal member 18 and the bottle 11 via the solder layer 21 and the inner lead 17.

Next, the method of use and effect will be explained.

When setting the axial ICI in the socket 4, insert the bottle 3 into the predetermined insertion hole 9 of the socket 4 into the holding hole 1 of the holding plate 8.
Insert it through 4. By operating the lever 13, the presser plate 8 slides against the input section main body 7, and the presser hole 14
presses the pin 3't- and inserts the axial ICI into the socket 4.
to be held mechanically. Bottle 3 inserted into insertion hole 9
are appropriately contacted by the elastic force of the input terminal member 10. Therefore, the bin 3 has an input terminal member 10. Bin 11° Solder layer 21. Output terminal member 1 via inner lead 17
It will be electrically connected to 8.

In this state, a second solder layer 22 is pre-formed on the chamfered portion 20 of the through hole 160 that connects to the input terminal member 10 of the insertion hole 9 into which the pin 3 corresponding to the ground or VCC terminal in the axial ICI is inserted. There is. This results in p1 grand or ■. , the terminal pin 3 is connected to the surface ground layer 19 via the second solder layer 22, and is electrically connected via this surface ground layer 19.

Therefore, since the ground line is connected (grounded) over a wide area, the ground line is electrically strengthened. Furthermore, since the surface earth layer 19 substantially covers the lower surface of the socket 4 (the lower surface of the output section main body 15), it also exhibits a magnetic shielding effect and blocks noise. In addition, surface earth layer 1
9 is not limited to being formed on one surface, but may be divided into multiple surfaces as necessary.

In addition, if necessary, a capacitor 2 may be inserted between the vias 11 that pass through the through hole 16 and protrude from the bottom surface of the output section main body 15.
3 is installed.

In this way, by setting the axial IC in the socket, the differential number 1 and axial I from the tester are
The response signal from C will be transmitted via the socket.

When removing the axial IC 1t from the socket 4, the holding of the presser plate 8 is released by pulling up the lever 13.

〔effect〕

(2) By attaching a surface ground to the bottom surface of the socket, it can be grounded or ■. Strengthening of the C line can be easily achieved, and a shielding effect can also be obtained.

(3) By attaching a surface ground to the bottom surface of the socket, the ground or VCC line can be easily strengthened, and a magnetic shielding effect can also be obtained, so noise during inspection can be reduced and inspection can be performed with high accuracy.

Although the invention made by the present inventor has been specifically explained above based on Examples, it goes without saying that the present invention is not limited to the Examples and can be modified in various ways without departing from the gist thereof. Nor.

For example, the structure for holding the axial IC in the input section is not limited to the above structure, and may be omitted.

The shape of the output terminal is not limited to the illustrated example, and can be selected as necessary depending on the connection with the tester. [Field of Application] The above explanation mainly focuses on the invention made by the present inventor as a background. Although the application field of axial IC is applied to a socket for connecting to a tester, it is not limited to this, for example, when electronic components or electronic equipment having a large number of terminals are mounted on a board.
