Abstract
The utility model discloses a kind of sealing gasket for automotive connector, it coordinates with the terminal be positioned on automotive connector, sealing pad comprises shim body, the obverse and reverse of described shim body is equipped with some for the blind hole through described terminal, the blind hole position in described shim body front is just to the blind hole position of described shim body reverse side, and all described blind holes are less than the cross-sectional area of described blind hole away from the one end at described shim body center at the cross-sectional area of the one end near described shim body center.Compared with prior art, shim body described in the utility model is arranged blind hole instead of traditional through hole, not easily residual scrap gum, improve sealing property, production difficulty coefficient reduces greatly simultaneously.
Description
Technical field
The utility model relates to a kind of sealing gasket, particularly relates to a kind of sealing gasket for automotive connector.
Background technology
Terminal on automotive connector needs to use sealing gasket to carry out air-isolation usually, on existing sealing gasket is through hole for each hole through terminal, in order to increase sealing, the cross-sectional diameter of this through hole is not of uniform size, this through hole is waveform, cause being easy to residual scrap gum in this through hole, this scrap gum may hang on terminal affects terminal conducting, in addition, adopt this frame mode sealing gasket and terminal fitted seal bad, risk less than normal is had during air tightness test, bubble-tight air pressure may be less than 0.10MPa, and the little mold insert that time shaping, sealing gasket is middle is easily broken, difficult processing.
Therefore, be necessary to provide a kind of new sealing gasket to solve the problems referred to above.
Utility model content
The purpose of this utility model is to provide a kind of not easily residual scrap gum, good seal performance, the sealing gasket for automotive connector that production difficulty coefficient is low.
To achieve these goals, the technical scheme that adopts of the utility model is as follows:
A kind of sealing gasket for automotive connector, it coordinates with the terminal be positioned on automotive connector, sealing pad comprises shim body, the obverse and reverse of described shim body is equipped with some for the blind hole through described terminal, the blind hole position in described shim body front is just to the blind hole position of described shim body reverse side, and all described blind holes are less than the cross-sectional area of described blind hole away from the one end at described shim body center at the cross-sectional area of the one end near described shim body center.
Preferably, all described blind holes are according to several rows of mode arranged in parallel, and the distance in each row often between adjacent two described blind holes is equal.
Preferably, described shim body front is also provided with location mold insert, and all described blind holes are symmetrical arranged about described location mold insert.
Preferably, described location mold insert is perpendicular to described shim body.
Preferably, the cross-sectional area of described location mold insert is rear constant to first increasing gradually near one end of described shim body from the one end away from described shim body.
Preferably, the sidewall of described shim body is also provided with the closed curve shape sealing gasket of at least two-layer protrusion.
Compared with prior art, the utility model is for the beneficial effect of the sealing gasket of automotive connector: shim body described in the utility model is arranged blind hole instead of traditional through hole, not easily residual scrap gum, improve sealing property, production difficulty coefficient reduces greatly simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of the existing sealing gasket for automotive connector;
Fig. 2 is the structural representation of the utility model for the sealing gasket of automotive connector;
Fig. 3 is the structure cross-sectional schematic of the utility model for the sealing gasket of automotive connector;
Fig. 4 is the front view of Fig. 3.
Embodiment
Below in conjunction with specific embodiment, the utility model is described further.
Refer to shown in Fig. 2 to Fig. 4, the utility model coordinates with the terminal 2 be positioned on automotive connector for the sealing gasket of automotive connector, sealing pad comprises shim body 1, described shim body 1 adopts rubber to make, the obverse and reverse of described shim body 1 is equipped with some for the blind hole 3 through described terminal 2, the terminal 2 that the area of the maximum cross section of this blind hole 3 is less than or equal to described automotive connector stretches into the cross-sectional area of the part of described blind hole 3, blind hole 3 position in described shim body 1 front is just to blind hole 3 position of described shim body 1 reverse side, the central symmetry axis of the positive and negative blind hole 3 that every two positions are relative is identical, all described blind holes 3 are less than the cross-sectional area of described blind hole 3 away from the one end at described shim body 1 center at the cross-sectional area of the one end near described shim body 1 center, described in each, arbitrary cross section of blind hole 3 is circle.
In the present embodiment, all described blind holes 3 are according to several rows of mode arranged in parallel, and the distance in each row often between adjacent two described blind holes 3 is equal.In the present embodiment, described blind hole 3 is provided with four rows, during embody rule can as required blind hole 3 described in appropriate change row and often arrange the quantity of blind hole 3.
In addition, described shim body 1 front is also provided with a registration mold insert 4, and described location mold insert 4 is perpendicular to described shim body 1.All described blind holes 3 are symmetrical arranged about described location mold insert 4, and are distributed in the both sides of this registration mold insert 4.The cross-sectional area of described location mold insert 4 is from the one end away from described shim body 1 to constant after first increasing gradually near one end of described shim body 1, and this structural design mode is convenient to described location mold insert 4 and is carried out coordinating with described automotive connector and locate.
The sidewall of described shim body 1 is also provided with the closed curve shape sealing gasket 5 of at least two-layer protrusion, described closed curve shape sealing gasket 5 can strengthen the sealing effectiveness of described shim body 1 sidewall further.In the utility model, described closed curve shape sealing gasket 5 comprises four sections of straight line portioies and four arcs line part, and the straight line portion of described closed curve shape sealing gasket 5 is connected with circular arc line part successively head and the tail.
During use, described location mold insert 4 coordinates with described automotive connector and positions, terminal 2 on described automotive connector inserts the blind hole 3 in described shim body 1 front, and puncture the blind hole 3 in described shim body 1 front and the blind hole 3 of described shim body 1 reverse side successively, because described shim body 1 adopts rubber to make, there is certain elasticity, the rubber at the edge of the blind hole 3 be punctured tightly can wrap up the outer wall of described terminal 2, the air-tightness coordinated with terminal 2 rises to 0.15MPa from 0.10MPa, and air-tightness is highly improved.
Schematically above be described the utility model and execution mode thereof, this description does not have restricted, and also just one of the execution mode of the present utility model shown in accompanying drawing, actual structure is not limited thereto.So, if those of ordinary skill in the art enlightens by it, when not departing from the utility model and creating aim, design the frame mode similar to this technical scheme and embodiment without creationary, protection range of the present utility model all should be belonged to.
