Abstract

Disclosed is a sealing socket connector which is composed of a connector and a socket, wherein, the connector and the socket form mutual socket joint; the tail ends of the connector and the socket are lead incoming pipes; two groups of lead terminals are connected in the connector and the socket; the sealing socket connector is characterized in that elastic colloid is filled in an annular cavity body positioned between a periphery jacket and a centre core post in the socket, and the annular head face of the elastic colloid and the connector matched to be arranged form sealing. The sealing socket connector is the sealing socket connector having reliable connecting performance and sealing performance, and is especially suitable to be applied in conditions having shock.

Description

Hermetically sealed connector

Technical field

The utility model relates to the connector of implementing connection between lead.

Background technology

Connector is that there are following relevant issues in the connector in the prior art with the connection between the mutual socket joint enforcement lead between a pair of plug-in unit and the socket:

1, contacts for end face between plug-in unit and the socket, this way of contact makes the operation of producing and assembling all fairly simple, but the poor sealing between the end face, have the gap between finishing after the assembling between the end face, when being applied to automative wiring, because the vibrations in the vehicle traveling process, connector can be because rocking appears in the gap that assembling stays, cause the contact performance of connector to descend, binding post voltage drop each other increases, and influences the operating state of car load.

2, the locking structure of binding post is to increase shell fragment is set on binding post, carries out locking by shell fragment in connector; But in since shell fragment thinner, holding capacity is less, flexible type causes binding post to be deviate from easily.

3, for the conduction wire harness that has external protection; when utilizing connector of the prior art to connect; owing to can't cooperate between wire harness outer protection material and the connector; cause the lead of connector afterbody always to have one section to expose; this lead that makes this section expose can not obtain corresponding protection; be worn easily, if the wrapping tension, the stressed increase between lead and binding post and binding post and the connector.

The utility model content

The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of hermetically sealed connector with reliable switching performance and sealing property is provided, being beneficial to use in having the occasion of vibrations.

The utility model technical solution problem adopts following technical scheme:

The utility model hermetically sealed connector is made of the plug-in unit and the socket of mutual socket joint, and the afterbody of described plug-in unit and socket is the inlet wire pipe, and two groups of conductor terminals are connected in described plug-in unit and socket.

Design feature of the present utility model is in socket, in the annular housing between its peripheral sheath and center core column, is filled with elastic gel, forms sealing with the end face of the annular end face of described elastic gel and the plug-in unit that is equipped with.

Design feature of the present utility model also is:

Described elastic gel is the circular cylindrical gum cover.

In described plug-in unit and socket, from the sidepiece of plug-in unit and socket, along the direction setting of inserting perpendicular to conductor terminal, lateral insert is set, and is provided with and is embedded in locking board in the lateral insert from sidepiece, described conductor terminal is formed locking with the shoulder of correspondence position on the described locking board.

On the afterbody inlet wire pipe of described plug-in unit and socket, flexible sheath is set.

On the mouth of pipe of the afterbody inlet wire pipe of described plug-in unit and socket, be provided for articulating the mouth hanging of flexible sheath.

Compared with the prior art, the utility model beneficial effect is embodied in:

1, the utility model has formed end face seal with the end face of elastic gel annular end face and the plug-in unit that is equipped with; increasing sealing part on the one hand makes binding post obtain seal protection; eliminated the fit clearance between plug-in unit and the socket on the other hand; improved connection reliability, be particularly suited in having the occasion of vibrations, using.

2, the utility model elastic gel is set to the circular cylindrical gum cover, is convenient to assembling, and is replaceable.

3, in the utility model lateral insert and locking board be equipped with the locking of having realized reliably for conductor terminal, reliable in structure, assembling process is simple.

4, the utility model had both increased sealing part at the afterbody inlet wire pipe of plug-in unit and socket and the setting that inserts flexible sheath between the lead; lead is effectively protected; the power that involves between lead, binding post and the connector is reduced greatly, can effectively prolong the useful life of device.

5, the mouth hanging that is provided with on the afterbody inlet wire pipe mouth of pipe of plug-in unit and socket of the utility model makes the fixed form of flexible sheath and plug-in unit and socket more simple, makes its fixed structure more reliable.
