Problems solved by technology

[0002] In the case of electronic equipment, especially in the case of communication equipment, there are many types of boards and there are high requirements for correct insertion in the corresponding position. Board-to-cable anti-mis-insertion, etc., but there is no anti-mis-insertion structure between front and rear boards
At present, there are single-board-to-backplane anti-wrong-mating structures, such as figure 1 As shown, the hole 101 on the positioning block 01 is used to cooperate with the needle 102 on the positioning block 02, the mounting surfaces 107, 108 are fixed, the structure is complicated, the cost is high, and there are few changes

Embodiment 1

[0028] Such as Figure 2a and 2b As shown, the cylinder of the veneer misinsertion prevention guide block 03 is in the shape of a square, and its matching positioning surface 104 has an inclined surface 1041, and the two ends of the inclined surface 1041 have vertical surfaces 1042 and 1043, when the vertical surface is mated, it can improve the safety and safety strength of mated mating. When the two anti-mis-insertion guide blocks are matched, the positioning surfaces 104 of the two anti-mis-insertion guide blocks are bonded together. If it cannot be inserted in place, it can prevent mis-insertion. Taking the positioning surface of the guide block as the front, its four sides, the bottom side 1061, the upper side 1062, the left side 1063 and the right side 1064 can all be used as the cylinder mounting surface, and the mounting hole 103 is arranged on the mounting surface, so The mounting hole mentioned above is a through hole, and the mounting hole can be a threaded hole ...

Embodiment 2

[0035] In another embodiment of the present invention, the cylinder of the anti-mis-insertion guide block is connected with a shell with at least one end open, the cylinder is installed in the shell through the open end of the shell, and the positioning surface is located outside the shell.

[0036] The shape of the housing can be the same as that of the cylinder, and the cylinder and the shell can be connected by any active connection structure in the prior art. For example, the mounting surface of the cylinder has a slide groove, and the connecting surface of the shell and the cylinder has a corresponding slide The rail and the cylinder can be movably connected as a whole through the chute and the slide rail. By connecting different sides of the cylinder with the shell, the position of the cylinder can be adjusted, and multiple anti-misplug combinations can be realized. The shell has a connection surface with the single board, and the connection surface is connected with the...

Abstract

The invention relates to a veneer guide block for preventing misplug and a veneer device with the anti-misplug guide block. The anti-misplug guide block includes a plurality of plane cylinders which are provided with a locating surface. The locating surface is provided with an inclined plane; the veneer device with the anti-misplug guide block includes a veneer and the anti-misplug guide block. The guide block cylinder is provided with an installation surface and the installation surface is provided with a connecting device which is connected with the veneer. The veneer is provided with a connecting device corresponding to the guide block; the guide block is connected with the front end of the veneer through the connecting device. The locating surface faces the front direction of the veneer. The invention has the advantages of simple structure and low cost; the invention has a plurality of combinations available, thus a plurality of veneers can be inserted into corresponding positionsone by one. therefore, the anti-misplug device is practical.

Description

technical field [0001] The invention relates to a single board anti-mis-insertion guide block and a single-board device with the same, in particular to a single-board anti-mis-insertion guide block on electronic equipment and a single-board device with the above-mentioned anti-mis-insertion guide block . Background technique [0002] In the case of electronic equipment, especially in the case of communication equipment, there are many types of boards and there are high requirements for correct insertion in the corresponding position. Board-to-cable anti-mis-insertion, etc., but there is no anti-mis-insertion structure between front and rear boards. At present, there are single-board-to-backplane anti-wrong-mating structures, such as figure 1 As shown, the hole 101 on the positioning block 01 is used to cooperate with the needle 102 on the positioning block 02, the mounting surfaces 107, 108 are fixed, the structure is complicated, the cost is high, and the changes are few....
