Description
Technical field:
The present invention relates to automobile, particularly the connector of electrical equipment on the automobile specifically is a kind of watertight connector that is used for automobile.
Background technology:
The connector of using on the automobile mainly is to be used for realizing being electrically connected and the signal transmission, can be divided into water proof type and non-water proof type by performance, non-watertight connector generally is used in the driving cabin does not need the position of waterproof with other, and watertight connector generally is used in the enging cabin needs the position of waterproof with other.Chinese invention patent application " rubber stopper and the water-proof connector that are used for water-proof connector " (August 11 2008 applying date; application number 200810144500.7; open day on February 11st, 2009) disclosed water-proof connector adopts the rubber stopper of two combination die forms; each combination die is provided with arc groove and forms waterproof construction to hold lead; if terminal then can't provide the waterproofing protection function when having vacant position, needing this moment increases seal at empty place.Existing multi-thread connector, when being used for when multi-thread, it is stifled that general line outlet in each position, hole of sheath is provided with an independent sealing, when realizing that with electric wire crimping is connected, terminal connects sealing stifled realization crimping simultaneously, make the stifled and terminal realization mechanical positioning of sealing like this, the location of terminal is realized sealing stifled location by sheath.The situation that terminal is had vacant position often appears when reality is used, this moment is not because the vacancy has lead, can't realize that generally sealing is blocked up and the mechanical positioning of socket sheath (or plug boot), main frictionally makes and seals stifled being fixed in the socket sheath (or plug boot).According to The Ideal-Gas Equation PV/T=C (C is a constant), when temperature T changes, C is a constant, volume V immobilizes, so connector gas inside pressure P will change, if the thrust that this pressure produces has surpassed the frictional force of the stifled and socket sheath (or plug boot) of sealing, sealing stifled will and sheaths separate, thereby make this connector lose waterproof effect.
Summary of the invention:
The object of the present invention is to provide a kind of watertight connector that is used for automobile, the described this watertight connector that is used for automobile to solve prior art sealing stifled can't and the terminal hole position between forms and is tightly connected reliably, cause sealing the stifled technical problem that loses waterproof effect with sheaths separate easily.
The objective of the invention is to be achieved through the following technical solutions: comprise terminal, sheath and seal member, terminal comprises sheet type plug and the sheet type socket that plugs cooperation, crimping is connected lead with sheet type socket with sheet type plug respectively, sheath comprises the plug boot of being located at sheet type plug periphery and the socket sheath of being located at sheet type socket periphery, plug boot one end is sheathed on socket sheath periphery, be provided with the terminal mounting hole site in plug boot and the socket sheath, black box comprises the stifled and sealing ring of sealing, sealing ring is located between plug boot and the socket sheath, wherein, be provided with a fixture in the stifled outer end of the sealing of plug boot, this fixture is fixedlyed connected with plug boot, and compress mutually with the stifled outer face of sealing in the plug boot, the stifled outer end of the sealing of socket sheath is provided with another fixture, this fixture is fixedlyed connected with the socket sheath, and compresses mutually with the stifled outer face of sealing in the socket sheath.
Described fixture is connected with plug boot by buckle structure, and described another fixture is connected with the socket sheath by buckle structure.
The terminal mounting hole site is at least 2 in described socket sheath and the plug boot, and it is stifled that the port of each terminal mounting hole site all is provided with a sealing.
Described sealing is stifled to connect and compose an integral body by plate shape connector, the plate shape connector of plug boot one end and plug boot end are tight fit, the plate shape connector of socket sheath one end and socket sheath end are tight fit, and fixture compresses mutually with the outer face of another fixture with plate shape connector.
Between the stifled and terminal mounting hole site of described sealing is interference fit.
Operation principle of the present invention is: to compress sealing stifled by setting up fixture for the watertight connector that is used for automobile of the present invention, sealing is stifled not to need that crimping is connected with terminal, by the mechanical positioning of fixture realization with socket sheath and plug boot, when even if lead is had vacant position, sealing stifled also not can with the position, hole between separate.
The present invention compares with prior art, and its effect is actively with tangible.To seal stifled compressing mutually and contact by set up fixture in plug boot and socket sheath end at the watertight connector that is used for automobile with the terminal mounting hole site of sheath, because between fixture and plug boot and the socket sheath is the mode of fixedlying connected, therefore sealing stifled needn't with terminal mutually crimping realize and the terminal mounting hole site between mechanical positioning, guarantee to seal the positiver sealing between stifled and the position, hole, guarantee the water resistance of connector.Plug boot and socket sheath can adopt the buckle mode respectively and between the fixture, and this connected mode is convenient to operation.If connector is the above multi-thread connector in position, 2 holes, the stifled integral seal that can adopt of sealing is stifled so, be provided with on a slab construction connector that a plurality of sealings are stifled to match with the position, hole, by fixture dull and stereotyped connector is compressed again, can realize the water-tight of connector, assemble more convenient; Simultaneously, when becoming the room even certain terminal mounting hole site place is not provided with terminal, sealing gets lodged under the fixture active force still and keeps good sealing with sheath, not can with sheaths separate, guarantee the waterproof effect of connector.If be interference fit between the stifled and corresponding terminal mounting hole site of each sealing, the residing space of terminal can obtain dual-seal like this, increases waterproof effect.
