Description

A kind of binding post

Technical field

The utility model belongs to field of power electronics, relates to specifically a kind ofly can satisfy pin type contact contacts demand with cellular type binding post simultaneously.

Background technology

In the power electronics industry, often need draw some signal of telecommunication of an equipment.This realizes through the signal terminal that holding wire is connected to equipment usually.But the existing cellular type binding post of signal terminal possibility of an equipment has the pin type binding post again.So, when running into the cellular type binding post, just need to use the binding post of column to insert in the wiring hole, so that draw signal; When running into the pin type binding post, just need to use the binding post of hollow to entangle the pin type binding post.When a lot of and existing pin type has the cellular type binding post again when the binding post of an equipment, just need to use different binding posts draw various signals, this just needs available for different connection modes, and relatively more inconvenient, wiring efficient is lower.

Summary of the invention

The problem that the utility model will solve is: existing binding post can not satisfy a lot of and existing pin type of binding post has the such user demand of cellular type binding post again, uses inconveniently, and wiring efficient is low.

The technical scheme of the utility model is: a kind of binding post, comprise insulation crust, spring, conducting sleeve, conductive contact and conducting resinl, and said conducting sleeve is socketed in the insulation crust, and conducting sleeve and insulation crust are fixed; Conductive contact comprises top column structure and bottom column structure, and top column inside configuration is a cavity, and the bottom surface of top column structure directly links to each other with bottom column structure end face; Conductive contact is connected with conducting sleeve through the bottom column structure; Wherein, the bottom column structure places in the conducting sleeve, and can slide; The bottom of the port of conducting sleeve and bottom column structure is provided with the buckle of pairing, when the bottom of bottom column structure slides into the port of conducting sleeve, blocks; Said spring housing and props up the bottom surface of column structure top, bottom and insulation crust on the column structure of the bottom of conducting sleeve and conductive contact, said bottom surface is insulation crust and conducting sleeve bottom face in contact; Described conducting resinl places the cavity of conductive contact.

The end face of said top column structure is the turbination end face, and the center of turbination end face is provided with jack, and the cavity of top column inside configuration communicates with jack.

The utility model has overcome the deficiency of existing binding post, and providing a kind of can both can connect the pin type binding post, can connect the binding post of cellular type binding post again.When appliance terminal is the pin type binding post; The pin type binding post of equipment can be realized wiring through the top jack that inserts this binding post; When appliance terminal was the cellular type binding post, this binding post can be inserted in the cellular type binding post of equipment and realize wiring, thereby need not to change binding post; Solve the loaded down with trivial details problem of wiring, thereby reduced production cost, improved operating efficiency.
