<Conventional technology> Conventionally, in order to connect terminals by inserting an IC card into the card slot of the main body of an information reading device, for example, a card holder on the terminal side built into the main body of the device was used.
The center portions of the upper and lower pieces of a leaf spring having a U-shaped cross section are bent inwardly so that the tips of the upper and lower pieces expand outward. In order to connect the terminals, a thin plated parallel multi-terminal was tightly inserted into the tip of one side of the IC card.

<Problems to be solved by the invention> However, when an IC card is inserted into the card slot of the main body of the device, the parallel multi-terminals of the IC card are subjected to a pressing force of 4 to 5 kg per unit area. The ends of the multi-terminals were scratched, and the expensive metal terminals were rubbed by the leaf springs and peeled off, causing connection failures.

This idea was made in view of the above circumstances.
The purpose of this is to make it easy to insert circuit boards such as IC cards and cartridge-type printed circuit boards into the insertion slot of the main body of the device, and to securely and firmly fix the terminals together with one-touch operation after insertion. To generally provide a connecting device for an insertion type board terminal, which allows the board to be easily removed by operating a lever, and also prevents damage to the board terminals.

<Means for Solving the Problems> As a means for solving the above-mentioned problems, the present invention provides a short side of the holding plate 2 at a position close to the board insertion groove 1 so as to straddle the groove 1. A surface 2 that rotatably supports a shaft 2a on both sides of one end in the direction, and faces the board insertion groove 1 side on the other end side of the holding plate 2.
A spring 3 is disposed at position b to push up the holding plate 2, and the spring 3 is wound around the external exposed surface of the elastic roll 4 housed so as to partially protrude from the surface 2b of the holding plate 2 facing the board insertion groove 1 side. The terminals 5a of the attached film-like substrate 5 are positioned and fixed on the outside, and the surface 2b of the holding plate 2 faces the substrate insertion groove 1 side.
This is a plug-in type board terminal connecting device characterized by being provided with a roll cam 7 with a lever 6 that comes into contact with the surface 2c on the opposite side.

<Function> To explain the function of the present invention configured as described above, first, before inserting an IC card A or a cartridge-type printed circuit board (not shown) into the board insertion groove 1, one end of both sides in the transverse direction must be The other end of the holding plate 2, which is rotatably supported, is pushed up by a spring 3 in a direction away from the groove 1, and the surface 2b of the holding plate 2 is pushed up by a spring 3 in a direction away from the groove 1.
The external exposed surface of the elastic roll 4 stored so as to partially protrude from the surface and the film-like substrate 5 wound thereon.
Terminal 5a is also located away from groove 1.

Next, IC card A or the like is inserted into the board insertion groove 1 with the terminal a side facing up, and the card A is inserted until the tip of the card A hits the end surface 1a of the groove 1. With the IC card A etc. fully inserted into the groove 1, hold the lever 6 and rotate it by a certain angle.The surface 2c that is in contact with the roll cam 7
The holding plate 2 on the side rotates about the shaft 2a, and the spring 3 becomes compressible against the spring force of the spring 3, and the holding plate 2, which had been facing diagonally, gradually changes its angle. almost parallel. In the process of the holding plate 2 becoming parallel to the groove 1, the terminal 5a of the film-like substrate 5 wound around the elastic roll 4 partially protruding from the surface 2b of the holding plate 2 comes into contact with the terminal a of the IC card A, etc. Initially, it is gradually deformed against the elastic force of the elastic roll 4, and firmly presses the terminal a portion of the IC card A, etc. When taking out the IC card A etc. from the groove 1, by holding the lever 6 and rotating it back to its original position, the elastic roll 4 separates from the groove 1 and the card etc. can be taken out easily.

<Example> Next, an example of the present invention will be described based on the drawings shown in FIGS. 1 to 4.

The terminal connection device according to the present invention is normally housed in a device body (not shown), but in this example, a case will be explained in which it is taken out from the device body and assembled into a housing 8 as shown in FIG. . The casing 8 has a bottom plate 9 having a groove 1 for inserting a board such as an IC card A on the top surface 9a and a bearing part 9b for the holding plate 2, and a bottom plate 9 which is installed on the rectangular periphery of the top surface 9a of the bottom plate 9 and has a bearing part for the roll cam 7. A rectangular frame 10 having a portion 10a at the top, and a frame 10 that closes the frame 10.
It consists of a plate-shaped lid 11 which is fixed to the upper surface 10b and has a window 11a through which the lever 6 projects.
