Abstract

The utility model relates to a switch-on connection field of power and signal provides a quick change formula connector, including preceding sleeve, back sleeve, hat spring, solid contact pin, hollow plug, guide head, exhaust hole. The utility model discloses the jack middle part is connected through solid plug, and solid plug inserts and takes the internal realization elastic contact of elastic crown spring, can realize quick tight fit and connect. The utility model discloses simple structure has anti-vibration, shock-resistant, but under the condition of not destroying jack main part and cable quick replacement terminal, and crown spring wearing resistance grow temperature rise is unusual or pile up the dust in the jack, behind materials such as water stain, dismantles the jack fast and dismantles the change, and need not destroy jack main part position, has reduced the maintenance cost and the material cost in later stage.

Description

Quick-change connector

Technical Field

The utility model belongs to the on-state connection field of power and signal, concretely relates to quick change connector.

Background

The existing connector plug-in units are all of an integrated connector structure, connecting ends cannot be replaced, and in the field requiring frequent tight fit, the tight fit easily causes abrasion of crown springs at contact parts; in the place that service environment is relatively poor, the contact site crown spring is inside often piles up the dust easily, and material such as water stain leads to burning out the jack in carrying out high-power charging process, influences the safety in utilization of connector.

SUMMERY OF THE UTILITY MODEL

To this situation, the utility model provides a quick change connector can effectively solve the problem that prior art exists.

In order to achieve the above purpose, the utility model provides a technical scheme as follows: a quick-change connector is characterized by comprising a front sleeve, a rear sleeve, a crown spring, a solid contact pin, a hollow plug, a guide head and an exhaust hole;

the novel plug pin connector is characterized in that a crown spring is arranged in the front sleeve, an exhaust hole is formed in the wall of the front sleeve, two ends of the front sleeve are both in an open shape, one end of the front sleeve is in tight fit connection with a solid contact pin, the other end of the solid contact pin is in tight fit connection with the rear sleeve, the crown spring is arranged in the rear sleeve, one end of the rear sleeve, which is connected with the solid contact pin, is in an open shape, and the exhaust hole is formed in the wall of the rear sleeve.

Preferably, the crown springs are respectively composed of two ends and a plurality of interconnected strips arranged between the two crown spring ends and arranged in parallel along the circumferential direction of the crown spring ends.

Preferably, the interconnection strip and the crown spring are arranged at a certain included angle.

Preferably, one end of the rear sleeve, which is far away from the front sleeve, is provided with a hollow plug.

Preferably, the hollow plug is provided with a guide head structure.

The utility model discloses the beneficial effect who has does:

the utility model provides an interconnection strip piece is the parabola shape inwards sunken for the internal diameter in crown spring middle section is less than the internal diameter at both ends, has the power of gripping after cooperating with solid cylinder, connects the fastening, has reliable electrical contact, avoids contact failure to produce the spark, still has very high participate in and extracts the resistance. Through the plug-in components design with the connector for can dismantle change structure, the compatibility is good, does benefit to the product upgrading, when the product of being connected with the connector upgrade, only need change partial contact plug-in components just can, low cost, easy change, the commonality is good.
