Abstract

(57) [Summary] [Structure] A plurality of sockets 10 are mounted on the board 20, and an integrated circuit 30 having a DIP structure is inserted therein. The socket 10 is provided with a plurality of jumper terminals in the lateral direction corresponding to each lead wire of the integrated circuit 30. Further, the plurality of horizontal jumper terminals are electrically connected to each other. Insertion terminals are attached to both ends of the jumper wire 20 to be inserted into jumper terminals of each socket 10 for electrical connection. Wiring between integrated circuits is performed via jumper wires 20. [Effect] Wiring and wiring changes can be easily made without damaging the board, terminals, etc.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a circuit evaluation tool, especially for DIP structure (Dual inline This invention relates to an evaluation tool for circuits using integrated circuits (package).

0002

[Conventional technology]

Conventionally, when evaluating a circuit using an integrated circuit with a DIP structure, multiple Circuit evaluation is performed by wiring between integrated circuits using wrapping and soldering.

0003

[Problem that the idea aims to solve]

As mentioned above, conventionally, wiring between each integrated circuit was done by wrapping or soldering. Since we are evaluating the circuit, not only is wiring and wiring changes time-consuming, but There is a problem in that it may cause damage to the board, terminals, etc.

0004 The purpose of this invention is to facilitate wiring and wiring without damaging the board or terminals. The objective is to provide a circuit evaluation tool that can be modified.

[0005]

[Means to solve the problem]

The circuit evaluation tool of the present invention is an evaluation tool for circuits using integrated circuits with a DIP structure. a plurality of leads arranged longitudinally along a plurality of leads of the integrated circuit; A plurality of lead contact terminals that each contact a lead wire, and a power supply for each lead contact terminal. It has multiple jumper terminals that are electrically connected and arranged horizontally. a socket, a board with multiple sockets installed, and a socket inserted into the jumper terminal. It consists of multiple jumper wires with terminals at both ends for electrical connection. It is.

【Example】

Next, the present invention will be explained with reference to the drawings.

[0007] FIG. 1 is a diagram showing an embodiment of a socket used in the circuit evaluation tool of the present invention. (a) is a perspective view, and (b) is a sectional view taken along the line A-A' shown in (a). socket The kit 10 has a plurality of terminals arranged in the vertical and horizontal directions, and an integrated circuit in the center. A groove 15 for mounting is provided in the vertical direction. Multiple leads on integrated circuits The wires are inserted into the holes provided adjacent to the groove 15, and are provided inside each hole. The terminals 11 and 12 are electrically connected to each other. Also, adjacent to each terminal 11, 12, A plurality of jumper terminals 13 and 14 are electrically connected to each other in the horizontal direction. Arranged.

[0008] Here, jumper wires 20 are used when wiring between integrated circuits. jumper wire Insertion terminals 21 are attached to both ends of 20 for electrical connection by inserting them into jumper terminals. It is attached.

[0009] FIG. 2 is a plan view showing how the circuit evaluation tool is used. The board 20 has a plurality of A socket 10 is mounted, and an integrated circuit is inserted into each socket 10. Also, the jumper wire 20 is inserted into the jumper terminal of the socket, and the jumper wire 20 is inserted between the integrated circuits. Wiring is being done.

0010

[Effect of the idea]

As explained above, the circuit evaluation tool of the present invention has multiple jumper terminals. A socket is placed on the board, with insertion terminals on both ends that can be inserted into jumper terminals. By wiring between integrated circuits using jumper wires, it is possible to It has the effect of allowing easy wiring and wiring changes without causing damage. There is.
