Abstract
The utility model discloses a waterproof connector assembly comprising a connector assembly female seat and a connector assembly male seat. High-voltage pins are disposed on the connector assembly male seat. The connector assembly male seat and the connector assembly female seat are both equipped with weight-reducing recessed chambers and are provided with waterproof sealing members outside the weight-reducing recessed chambers. An annular isolating sleeve around the high-voltage pins is disposed in the weight-reducing recessed chamber of the connector assembly male seat. A waterproof washer in sealed cooperation with the end face of the annular isolating sleeve is disposed in the weight-reducing recessed chamber of the connector assembly female seat. In the waterproof connector assembly, the waterproof sealing member is a first waterproof sealing unit for preventing air water from contacting the high-voltage pins, and the annular isolating sleeve and the waterproof washer form a second waterproof sealing unit for preventing air water from contacting the high-voltage pins. The double-layer waterproof sealing design effectively prevents the air water from corroding the high-voltage pins and influencing the performance of the connector assembly, and prevents electric leakage potential safety hazards of the connector assembly.
Description
Technical field
The utility model relates to a kind of connector, particularly a kind of water-proof connector.
Background technology
Connector comprises contact pin part and jack part, connector for electric energy transmitting and the signal of telecommunication, require it to there is good water resistance, if have water or steam to enter connector, can corrode and connect pin part, affect its performance, and for high-voltage connector, aqueous vapor also can reduce the insulation degree of connector insulation board and metal part, makes connector have electrical shock safety hazard.
Connector of the prior art, changes electric connector as the Chinese application number disclosed a kind of electric automobile of patent that is 201120481802.0 fills, and has plug and socket, is respectively equipped with waterproof apron, to realize the water-proof function of electric connector on plug and socket; This connector is because waterproof apron is without any fixed structure, and water resistance is poor.For another example the disclosed a kind of high voltage connector of electric automobile of patent that Chinese application number is 201120375966.5, on the circumference at insulator fitting tight circle place, design three road reinforcements, sealing ring is arranged in reinforcement groove, for guaranteeing the sealing of connector installed surface; This connector is had relatively high expectations to sealing ring, and the size of sealing ring, material, useful life etc. all need to meet the requirements, and have a condition not possess, and the water proofing property of connector will be damaged, and this can not in use be guaranteed connector water resistance.
Particularly in the environment of variations in temperature, connector internal gas can expand, shrink with rising, the reduction of temperature, if connector waterproof construction poor sealing, just steam is easily inhaled in connector when connector air pressure inside reduces, and then affects performance of connector.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of water-proof connector, to solve existing connector, can not well stop steam to enter the problem of connector.
The utility model water-proof connector, comprises plug-in unit female seat and plug-in unit male seat, in described plug-in unit male seat, is provided with high pressure contact pin, in described contact pin male seat and contact pin female seat, is provided with loss of weight cavity;
In described plug-in unit female seat and plug-in unit male seat, at loss of weight cavity, be outside equipped with waterproof seal;
In described plug-in unit male seat, in loss of weight cavity, be provided with the annular isolation cover being trapped among outside high pressure contact pin, in described plug-in unit female seat, in loss of weight cavity, be provided with the waterproof washer coordinating with the end face seal of annular isolation cover.
Further, described annular isolation puts and is provided with the Non-return air valve that gas in annular isolation cover is entered to loss of weight cavity.
Further, described waterproof seal comprises the spill waterproof grommet in fixing pluge female seat and is fixed on the convex waterproof grommet being sealed and matched with spill waterproof grommet in plug-in unit male seat.
The beneficial effects of the utility model:
1, the utility model water-proof connector, its waterproof seal is the first heavy waterproof sealing that prevents air water contact high pressure contact pin, its annular isolation cover forms with waterproof washer the second heavy waterproof sealing that stops air water to contact high pressure contact pin, by double-deck waterproof sealing, design, can affect performance of connector by more effective prevention air water corrosion high pressure contact pin, and can stop the electric leakage potential safety hazard of connector.
2, the utility model water-proof connector, the Non-return air valve of its setting can enter loss of weight cavity by the gases at high pressure in annular isolation cover, thereby makes annular isolation cover inside and outside air pressure balance, can avoid gases at high pressure to destroy hermetically-sealed construction.
Accompanying drawing explanation
Fig. 1 is the vertical view of the utility model water-proof connector;
Fig. 2 is along the cutaway view of A-A in Fig. 1.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in the figure, the present embodiment water-proof connector, comprises plug-in unit female seat 1 and plug-in unit male seat 2, in described plug-in unit male seat 2, is provided with high pressure contact pin 3, in described contact pin male seat 2 and contact pin female seat 1, is provided with loss of weight cavity 4;
In described plug-in unit female seat 1 and plug-in unit male seat 2, at loss of weight cavity 4, be outside equipped with waterproof seal 5;
In described plug-in unit male seat 2, in loss of weight cavity 4, be provided with the annular isolation cover 6 being trapped among outside high pressure contact pin 3, in described plug-in unit female seat 1, in loss of weight cavity 4, be provided with annular isolation and overlap the waterproof washer 7 that 6 end face seals coordinate.
The present embodiment water-proof connector, its waterproof seal 5 forms the first heavy waterproof sealing that prevents air water contact high pressure contact pin 3, its annular isolation cover 6 forms with waterproof washer 7 the second heavy waterproof sealing that stops air water to contact high pressure contact pin 3, by double-deck waterproof sealing, design, can affect performance of connector by more effective prevention air water corrosion high pressure contact pin, and can stop connector appearance electric leakage potential safety hazard.
As the improvement to this enforcement, on described annular isolation cover 6, be provided with annular isolation is overlapped to the Non-return air valve 8 that 6 interior gases enter loss of weight cavity 4, Non-return air valve 8 can enter loss of weight cavity by the gases at high pressure in annular isolation cover, thereby make annular isolation overlap 6 inside and outside air pressure balances, can avoid gases at high pressure to destroy hermetically-sealed construction, further improve sealing effectiveness.
As the improvement to this enforcement, described waterproof seal 5 comprises the spill waterproof grommet 51 in fixing pluge female seat 1 and is fixed on the convex waterproof grommet 52 being sealed and matched with spill waterproof grommet 51 in plug-in unit male seat 2, adopts the form ratio that concavo-convex sealing ring coordinates to adopt single waterproof grommet waterproof sealing effect better.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
