Description

The power connector composite construction of anti-mis-insertion

[technical field]

The utility model is a kind of power connector composite construction of anti-mis-insertion, refers to a kind of structure of coming off of being easy to especially, and it is simple in structure and make conveniently, can effectively reduce production costs, and prevent the operation that misplugs.

[background technology]

A kind of electric power connector is used, and has a plug socket and a connection-peg usually, and this plug socket system is arranged in the electronic installation, and this first end group of pegging graft is provided with a cable, and the other end then is to peg graft with this plug socket, has accomplished the supply of signal or power supply.

Traditional electric connector uses, and the fixing closely or close-fitting of connection-peg and plug socket system is to reach effective signal or power supply transmission; But because electronic installation in use, often has the cable that touches accidentally or pull connection-peg, be pulled away from usage platform,, will injure personnel what is more causing dropping and damaging of electronic installation to cause whole electronic installation.

Therefore; In the design of connector, what a kind of structure of easy disengaging will be slowly accepted by the consumer, that is being connected of plug socket and connection-peg; Outside taking effectively transmitting signals into account; It can be broken away under pullling improperly effectively, and reach the effect that is easy to break away from, just can avoid electronic installation to be pulled and the damage of dropping

Convention is a kind of to be prone to take off connector structure, please refer to United States Patent (USP) the 7th, 311, No. 526; It is to fix with the mode of magnetic absorption, that is on the contact-making surface of plug socket and connection-peg, is respectively arranged with two magnetic poles that attract each other, when general the use; This connection-peg and plug socket are that magnetic combines, and when meeting improper external force and pullling cable, are not needing bigger pullling under the power; Can make connection-peg break away from plug socket easily, so, can avoid electronic installation to be pullled and drop.

Above-mentionedly be prone to take off connector family and adopt the magnetic mode, its manufacturing cost is too high, and it is high to attach the cost that will make electronic installation, does not cause more and is accepted by the consumer, and relatively its popularity rate is less, is its shortcoming.

Therefore, industry be join hands to think how to design a kind of simple structure, structure is taken off in low being prone to of cost, not only can effectively carry out electric connection, and the connector that also can break away from easily.

In view of this, this creator is that this is joined hands in the connector research and development in the spirit of keeping on improving, innovate breakthrough, and creates the utility model electric connector and composite construction thereof, make it can reach the effect that is prone to disengaging, and it is cheap for manufacturing cost.

[summary of the invention]
