Description
Technical field
The present invention relates to technical field of automobile accessories, and in particular to a kind of plug for automobile fuel pump.
Background technique
Fuel pump is generally located in the fuel tank of automobile, for fuel oil to be delivered to internal combustion engine from fuel tank.Known combustion
Oil pump has one or two pump stage, they are by a motor driven.Since fuel pump is arranged in fuel tank, the fuel pump
Plug be also to be impregnated by fuel oil.And fuel oil is with corrosive substance, it corrodes the coupled position of plug.Especially work as
When fuel oil contains methanol or ethyl alcohol, coupled position is etched in this way, i.e., it is damaged for a long time and thus causes fuel pump
Failure.
To solve the above-mentioned problems, as shown in Figure 1, fuel pump plug in the prior art includes header body 1 and is located at
Pin 2 in header body 1；In the circle annular protrusion 5 that is circumferentially with of pin 2, and protrusion is fixedly connected with header body 1.
The socket aperture 41 being inserted into for pin 2 is all provided on the socket 4 of fuel pump；A circle is circumferentially with for convex annular in socket aperture 41
The annular groove 42 of 5 insertions is played, the inner bottom surface of annular groove 42 is equipped with the fixing groove 43 that a circle section is T shape.It is specifically used
When, directly pin 2 is inserted into socket aperture 41；Annular protrusion 5 is also inserted into annular groove 42 simultaneously, so that
Annular protrusion 5 can block fuel oil, prevent fuel oil from contacting with pin 2.
There are following technical problems for the prior art: since fuel pump is arranged in fuel tank, the plug of fuel pump is by fuel oil
Long period of soaking, having a small number of fuel oils can be immersed by annular protrusion 5 and the gap of the contact position of annular groove 42；Isolation effect
It is bad.
Summary of the invention
The purpose of the present invention is to provide a kind of plug for automobile fuel pump, it can guarantee that fuel oil will not connect with pin
Touching.
In order to achieve the above objectives, base case of the invention is as follows:
A kind of plug for automobile fuel pump, the pin including header body and in header body；It further include packet
It is rolled in the corrosion-resistant coating of header body outer surface, pin passes through corrosion-resistant coating；It is equipped in anti-corrosion corrosion layer for fuel oil entrance
Fuel pipe；A circle isolation ring is fixed on corrosion-resistant coating, and isolation ring is located at the circumferential direction of pin；Annular groove is equipped in isolation ring；
A circle annular air-pocket is equipped in annular groove, and annular air-pocket is connected to fuel pipe；Annular air-pocket is located remotely from the one of corrosion-resistant coating
Side.
The beneficial effect that this programme generates is:
1, this programme can guarantee that fuel oil will not be contacted with pin, while plug and socket can also be made to cooperate increasingly
Closely, it will not loosen；The principle is as follows: inserting the prongs in socket aperture；Isolation ring is inserted into annular groove；When plug quilt
After being soaked for a period of time, fuel oil can be entered in fuel pipe, and be entered in air bag by fuel pipe, air bag gradually expand after with
The inner bottom surface of annular groove is in close contact, and then prevents fuel oil from immersing between isolation ring and the contact surface of annular groove.In addition, gas
It can be entered in the fixing groove of annular groove inner bottom surface after capsule expansion；Since the section of fixing groove is T shape, air bag can be caught in
Into fixing groove；So that pin cooperates even closer with socket aperture, consolidation effect is realized.
2, the header body outer surface in this programme is wrapped up by corrosion-resistant coating, can protect to header body more complete
Face.
Preferred embodiment one: advanced optimizing as to base case, and the edge of corrosion-resistant coating upper surface is further fixed on
One circle rubber ring, and the entrance of fuel pipe is between rubber ring and isolation ring.
Rubber ring and isolation ring Double Fit, are further ensured that pin will not be with fuel contacts.When specifically used, combustion
Oil can be blocked first by rubber ring, after using rubber ring to damage, can just be entered in fuel pipe；At this point, air bag is expanded into
Into fixing groove, the reinforcing to the isolation of fuel oil and pin and socket aperture is realized.
Preferred embodiment two: the face as advanced optimizing to preferred embodiment one, between rubber ring and the entrance of fuel pipe
The inclined-plane tilted down for the entrance towards fuel pipe.It is entered in fuel pipe convenient for fuel oil by inclined-plane.
Preferred embodiment three: as advanced optimizing to base case or preferred embodiment two, corrosion-resistant coating is glassy layer.It is non-
Often simply realize the protecting effect to header body.
Preferred embodiment four: as advanced optimizing to base case or preferred embodiment two, corrosion-resistant coating is titanium alloy layer.
Titanium alloy intensity is high, corrosion resistance is good, heat resistance is high, simply realizes very much the protecting effect to header body.
Preferred embodiment five: as advanced optimizing to preferred embodiment four, a circle baffle is fixed on the cell wall of annular groove；
The side of baffle is contacted with annular air-pocket；And baffle is between annular air-pocket and corrosion-resistant coating.The setting of baffle is mainly
It can be expanded towards the direction of fixing groove after air bag is expanded.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of background technique；
Fig. 2 is a kind of structural schematic diagram of the plug for automobile fuel pump of the present invention；
Fig. 3 is the partial enlarged view of A in Fig. 2.
Specific embodiment
Below by specific embodiment, the present invention is described in further detail:
Appended drawing reference in Figure of description includes: header body 1, pin 2, corrosion-resistant coating 3, fuel pipe 31, isolation ring
