[0007]

[Problems to be solved by the device]

 However, the above-mentioned conventional techniques have various problems as described below. First, when inserting the card into the card unit for mounting on the card unit, make sure that the card-side connector has a highly accurate positioning so that it can be inserted and fitted properly into the housing of the corresponding backboard-side connector of the backboard. There is a need to. Also, the upper and lower plates, the side plates, and the backboard that form the card unit are assembled with each other, the manufacturing accuracy of these, the mounting accuracy of the backboard and the connector on the backboard side, the manufacturing accuracy of the backboard side connector, or The manufacturing accuracy of the card and the connector on the card side, the mounting accuracy of the card and the connector on the card side, etc. must all be taken into consideration, which not only increases the manufacturing man-hours and the assembly man-hours, but also requires high-precision component parts. There was a problem of causing high costs.

Further, the guide rail for guiding the insertion direction of the card has a width which is slightly wider than the thickness of the card, and the distance between the upper and lower plates is the same as the height direction of the card. Since there is only a small gap in the insertion, the insertion can be done relatively easily by hand, but it is very difficult to insert using an automatic machine, and even if possible, it is very expensive. In addition, an automatic inserter having a complicated and highly accurate mechanism is required, which further increases the cost. In addition, the card unit on the insertion side is the same as the card unit on the insertion side, which has become lighter due to the recent trend of light, thin, short, and small technologies. The mating connection secures not only electrical but also mechanical connection, but the upper and lower plates with guide rails are used to protect the card from falling, and a strong side plate for supporting the upper and lower plates is used. Since it is attempted to adopt an insertion mechanism by an automatic machine, it is not possible to omit these upper and lower plates and rigid side plates, which increases the card unit cost and the unit weight.

Further, in recent years, the size of the backboard has increased, and along with this, many backboard-side connectors are inevitably attached to one backboard, and at the same time the number of backboard-side connectors increases. Corresponding to, many cards will be installed. In this way, even with a backboard that is large and has a large number of cards mounted on it, the conventional card unit structure only fixedly supports the periphery of the backboard, so the backboard is centered around its center. There was also a problem in that it could be greatly deformed and deformed.

The present invention was made in order to solve the above-mentioned problems, and requires a highly accurate component member, or increases the number of assembling steps for assembling this with high accuracy. Due to the difficulty of automatic card insertion / removal with an automatic machine, the increase in weight of the card unit, and the bending of the backboard due to the mounting of many backboard side connectors and cards Preventing deformation, low cost and light weight, easy insertion operation by both automatic machines and human hands, and low cost and excellent card unit structure with no back board bending. The purpose is to provide.

[0011]

[Means for Solving the Problems] In order to achieve the above-mentioned object, according to the present invention, a thin plate-like card having a card-side connector at one side edge is fitted to a connector housing part arranged in a matrix. In a card unit structure in which a plurality of connector housings are mounted by mounting, the connector housing parts are collectively formed by an insulating member filling the space between the connector housing parts, and the connector housing parts are formed together. The inner peripheral surface of this is an integrated housing board that is a taper surface that is inclined in the direction that narrows inward from the opening side that is the insertion side when inserting the card. Then, on the back side of this integrated housing board, a thin plate-like backboard supporting a plurality of terminals provided in the connector housing to obtain an electrical connection with the card is attached to each connector. The integrated housing board and the backboard are integrated by fixing with a fixture at arbitrary multiple positions between the housing parts.

[0012]

[Action]

 According to the above-mentioned configuration, the connector housings to be fitted with the card-side connectors of the card are integrally formed in a matrix, so that the backboard is fixed by filling the insulating material of each connector housing. Since there is a wall thickness between each other that allows the use of fasteners such as screws, it is possible to use any number of fasteners at any position between them, which is why , The backboard and the integrated housing board can be fixed easily and securely to form the card unit. When a card is inserted into this card unit, the inner peripheral surface of the connector housing has a taper surface in a prescribed direction, so that the connector housing can be inserted even if the card insertion position is not sufficient. If the card-side connector is inserted into the housing, the card-side connector can be guided to the housing of the card unit to be fitted and connected. Therefore, it is not necessary to perform accurate positioning even when inserting with an automatic machine.
