SUMMERY OF THE UTILITY MODEL

The utility model solves the technical problem that: how to realize the smooth splicing of the terminal block.

In order to solve the technical problem, the utility model provides a following technical scheme: printed circuit board concatenation formula forked tail cooperation structure, including setting up protruding forked tail and the concave forked tail on the adjacent body of terminal platform, protruding forked tail and concave forked tail clearance fit are equipped with the stuck point on the body of adjacent body, be equipped with on another body with stuck point complex stuck point groove.

The male dovetail on one body in the adjacent body of the terminal block is in clearance fit with the female dovetail on the other body, and synchronously, the clamping point on one body in the adjacent body is in interference fit with the clamping point groove on the other body.

The cooperation of stuck point and stuck point groove is gone on when the cooperation of male dovetail and female dovetail is close to the completion, consequently, the cooperation of male dovetail and female dovetail is smooth and easy, and when the cooperation was ended, the interference fit in stuck point and stuck point groove also targets in place. Therefore, the production efficiency is improved.

Detailed Description

Combine fig. 6, fig. 7, printed circuit board concatenation formula forked tail cooperation structure, including setting up protruding forked tail 24 and the concave forked tail 23 on the adjacent body 20 of terminal platform, protruding forked tail and concave forked tail clearance fit are equipped with stuck point 22 on the body of adjacent body, be equipped with on another body with stuck point complex stuck point groove 21.

The clamping point 22 is in interference fit with the clamping point groove 21, so that under the condition that the male dovetail 24 is in clearance fit with the female dovetail 23, the splicing stability and tightness of the terminal block are realized.

The click groove 21 is provided at the top of the sidewall of the body 20, and the top end thereof is opened. In this way, the bayonet 22 can be fitted into the bayonet groove 21 through the top end opening of the bayonet groove during the process of fitting the male dovetail 24 and the female dovetail 23.

The clamping point 22 is wedge-shaped, and after the clamping point is matched in place, one end of the clamping point is abutted against the step of the clamping point groove, so that the matched limiting is realized.

Two parallel male dovetails 24 or female dovetails 23 are arranged on the same body 20, and the plugging direction of the male dovetails and the female dovetails of the adjacent bodies is the same as that of the clamping points 22 and the clamping point grooves 21. When the cooperation of male dovetail and female dovetail is close to accomplishing, stuck point 22 and the cooperation of stuck point groove 21, the cooperation of male dovetail and female dovetail, stuck point and stuck point groove accomplish simultaneously.

In actual assembly, as shown in fig. 10 to 16, the terminal 30 is inserted into the square box 31 to form a terminal and square box assembly 32, and the terminal and square box assembly 32 is inserted into the body 20 to form a terminal, square box and body assembly 34. The terminal, square box and body assembly 34 is assembled into the screw 33 to form a finished product 35, and the two finished products 35 are spliced into two finished assembly 36. The lead is inserted into the square box 31, and under the pressing action of the screw, the lead can be tightly pressed with the terminal 30.

The body 20 of any finished product 35 is provided with a female dovetail 23 and a male dovetail 24. Two adjacent bodies 20 are respectively a left body and a right body, the first male dovetail 241 of the left body is in clearance fit with the first female dovetail 231 of the right body, and the second male dovetail 242 of the left body is in clearance fit with the second female dovetail 232 of the right body.

The front side 212 of the click point of the left body is matched with the front side 222 of the click point groove of the right body in a buckling way, and the rear side 213 of the click point of the left body is matched with the rear side 223 of the click point groove of the right body in a buckling way.

The above description is only for the preferred embodiment of the present invention, and for those skilled in the art, there are variations on the detailed description and the application scope according to the idea of the present invention, and the content of the description should not be construed as a limitation to the present invention.
