Description

Through-wall wiring terminal

Technical Field

The utility model relates to an electric connector technical field specifically is a through-wall binding post.

Background

In the whole control system of the electromechanical product, a part of parts and circuits are often used as subsystems, and need to be packaged in an insulating box body to be used as a relatively independent part and isolated from an external main circuit. The production, the installation, the overhaul and the replacement can be conveniently and independently carried out. The sub-system and an external circuit can be communicated with each other through an electric connector capable of penetrating through the box body to jointly form a complete system. A through-wall terminal is one such electrical connector that facilitates the connection of internal circuitry to external circuitry. The existing wiring terminals in the market are rich in types, but are manufactured in batch, the specifications are relatively fixed, and the performance requirements under all use scenes cannot be met. Or the electrical performance of some connecting terminals can meet the current requirements, but the connecting terminals cannot be used due to the improper shape and size of the connecting terminals.

SUMMERY OF THE UTILITY MODEL

Under the condition that form, size and electrical property of present all kinds of binding post can not satisfy the demand, the utility model provides a simple and easy wall binding post, its simple structure, connect reliably, application scope extensively.

The utility model discloses the technical scheme who adopts as follows: a through-wall wiring terminal comprises an inner side insulating block, an outer side insulating block, three combined screws, a terminal conducting strip and a self-tapping screw.

The terminal conducting strip is arranged in the grooves of the inner insulating block and the outer insulating block and penetrates through the box body.

The terminal conducting plate is provided with 2 screw holes which are respectively positioned at two ends, and the three combined screws are screwed into the screw holes at the two ends of the terminal conducting plate to be used as binding posts and are respectively positioned at the inner side and the outer side of the box body and used for connecting wires.

The terminal is characterized in that 2 grooves are formed in the inner insulating block and the outer insulating block, the whole terminal is in a shape like a Chinese character 'shan', the groove parts can accommodate the terminal conducting strips, 1 blind hole is formed in the middle of each groove, and the three combined screws are screwed into the terminal conducting strips and then extend out of the blind holes to play a role in limiting.

The difference between the inner insulating block and the outer insulating block is only the bottom, the bottom of the inner insulating block is provided with 3 second blind holes in the horizontal direction, and the corresponding positions of the outer insulating block are 3 cylindrical counter bores.

And the self-tapping screw penetrates through the cylindrical counter bore of the outer insulating block and then taps into the second blind hole at the bottom of the inner insulating block, and the self-tapping screw can be fixed on the box body after being locked.

The utility model discloses the occasion that mainly is applicable to box body, box etc. need connect inside and outside circuit. The working principle is as follows: three combined screws respectively arranged at two sides of the box body are used as binding post fixing leads; the terminal conducting strip penetrates through the box body and is connected with the internal circuit and the external circuit; the inner insulating block and the outer insulating block play a role in limiting the terminal conducting strip; and finally, fixing the parts on the box body by self-tapping screws.

Compare with current all kinds of binding post, the utility model has the advantages of it is following: the structure is simple, and the production and the installation are convenient; the three-combination screw is used as a binding post, so that the wiring is flexible and the connection is reliable; the number and the size of parts can be freely customized according to the electrical performance requirements of specific use scenes, and the application range is wide.
