Description

Connector convenient to maintain and reliable in contact

Technical Field

The utility model relates to a connector provides a convenient connector of maintaining reliable contact very much.

Background

Contact resistance is an important indicator of connector production, and the presence or absence of stains on the contact surface is an important factor affecting the contact resistance of the connector. The contact point of the contact piece (wire spring, leaf spring) of conventional connector all is inside the contact piece, and is difficult for wasing, under adverse circumstances, in case there are dirt such as dust, oil stain on the contact point of contact piece, can make contact resistance increase, destroys the normal electrically conductive of electrical contact connection even, and the connector just can't normally be used.

Disclosure of Invention

An object of the utility model is to provide a simple structure has concurrently and shocks resistance and the convenient connector of maintaining reliable contact of antivibration.

The utility model adopts the technical proposal that: the utility model provides a conveniently maintain connector of reliable contact, is equipped with the contact pin subassembly including inserting plug and the socket that closes each other in the plug, is equipped with jack, its characterized in that in the socket: the needle assembly comprises a needle main body, a spring, a needle head and a steel ball, wherein the needle main body is axially provided with a needle head hole, an inward furling opening is formed in the opening of the needle head hole, a circle of limiting boss is arranged on the periphery of one end of the needle head, one end of the needle head penetrates through the needle head hole to be in a state that the limiting boss corresponds to the furling opening to be limited and prevented from falling off, the other end of the needle head is arranged outside the needle head hole, one end of the needle head is an inclined plane end, and the inclined plane end is; the jack is a solid cylinder, a conical groove which is correspondingly matched with the head of the other end of the needle head is arranged on the solid cylinder, and the depth of the conical groove does not exceed the radius of the ball head of the needle head.

Furthermore, the plug comprises a splicing cap, a clamping cap, a corrugated ring and a head shell, wherein the contact pin assembly is connected in the head shell in a penetrating manner through the needle insulator and the interface sealing body, and the head shell is clamped in the clamping cap through the splicing cap through the corrugated ring.

Further, the socket comprises a socket shell and a hole insulator, and the jack penetrates through the hole insulator and is connected in the socket shell.

Furthermore, the seat shell is provided with a bayonet corresponding to the guide groove of the inner wall of the bayonet cap in the guide cross-connecting plug.

After taking above technical scheme, the beneficial effects of the utility model are that: after the ball head structure at the other end of the needle head is inserted into the tapered groove on the end face of the solid jack cylinder, a contact point is arranged on the end face of the solid jack cylinder, and even if stains are on the contact point of the connector contact element in a general environment, the poor contact resistance of the connector occurs, the stains on the surface of the contact element are cleaned by alcohol cotton from the end face of the jack of the connector, so that the connector can be continuously used, and the maintenance operation is extremely convenient; the pin assembly is internally provided with a steel ball and a spring which tightly prop against the inclined plane end at one end of the needle head, so that when the connector impacts or vibrates axially or radially, impact and vibration can be effectively buffered, hard connection collision damage is prevented, and the connector has better impact resistance and vibration resistance.
