Embodiment
For enabling above-mentioned purpose of the present utility model, feature and advantage become apparent more, are described in detail embodiment of the present utility model below in conjunction with accompanying drawing.Set forth a lot of detail in the following description so that fully understand the utility model.But the utility model can be much different from alternate manner described here to implement, those skilled in the art can when doing similar improvement without prejudice to when the utility model intension, and therefore the utility model is by the restriction of following public specific embodiment.
It should be noted that, when element is called as " being fixed on ", " being arranged at " another element, directly can there is element placed in the middle in it on another element or also.When an element is considered to " connection " another element, it can be directly connected to another element or may there is centering elements simultaneously.Term as used herein " vertical ", " level ", "left", "right" and similar statement just for illustrative purposes, do not represent it is unique execution mode.
As shown in figures 1 and 3, aviation connect-disconnect plug 10 for sewage pump comprises: housing 100, screen 110, insulator 120, some contacts 130 and electric conductor 140, screen 110, insulator 120, some contacts 130 and electric conductor 140 are arranged in housing 100, housing 100 has containing cavity 150, and screen 110, insulator 120 and contact 130 are arranged in containing cavity 150.So, housing 100 can avoid the insulator 120 of exterior object and housing 100 inside, some contacts 130 and the direct of electric conductor 140 to contact, and meanwhile, is convenient to that user is stressed to be coordinated aviation connect-disconnect plug 10 with corresponding socket with.Further, also make whole aviation connect-disconnect plug 10 compact neat, effectively improve security performance and the stability of product.
In order to improve vibration proof performance, as shown in Figure 1, such as, housing 100 is provided with resilient coating 101, and resilient coating 101 is positioned at the opening of housing 100.Such as, resilient coating 101 is made for the wear-resisting material of resistance to bending, and such as, this wear-resisting material of resistance to bending is synthetic rubber.And for example, resilient coating 101 is this wear-resisting material of resistance to bending is organic polymer plastics.So, this resilient coating 101 is utilized effectively can to absorb the impulsive force produced when this aviation connect-disconnect plug coordinates with socket.
In order to improve air-tightness, as shown in Figure 3, such as, insulator 120 offers some installing holes 121, and some contacts 130 wear some installing holes 121 and are arranged on insulator 120.Such as, insulator 120 is made for elastoplast, the cross section of contact 130 is circular, the aperture of described installing hole 121 is slightly less than the diameter of the circular cross-section of contact 130, to make each contact 130 and each installing hole 121 interference fit, thus improve the air-tightness of contact 130 and each installing hole 121.
In order to improve stability when contact 130 conducts electricity, such as, one end away from housing 100 opening of each contact 130 abuts with electric conductor 140 and is electrically connected.As shown in Figure 4 and Figure 5, contact 130 is bar-shaped, and electric conductor 140 side offers the corresponding blind hole 141 of some blind hole 141, contacts 130, and one end of each contact 130 is placed in each blind hole 141.Such as, contact 130 and blind hole 141 interference fit.Such as, the bottom of described blind hole 141 is provided with the first conducting block 142, such as, the side opposing with described blind hole 141 is provided with the second conducting block 143 be connected with the first conducting block 142, abuts and is electrically connected after contact 130 is placed in blind hole 141 in the first conducting block 142.In the present embodiment, electric conductor 140 is that the insulating material of hard is made, and such as, electric conductor 140 is rigid plastics, so that install contact 130.So, under the effect of contact 130 and electric conductor 140, can prevent aviation connect-disconnect plug in the course of the work because the loosening phenomenon causing loop open circuit of contact 130.
In order to improve the antijamming capability of anti-aviation connect-disconnect plug, as shown in Figure 3, such as, housing 100 arranges screen 110, and screen 110 is arranged at the side of housing 100 towards insulator 120, and screen 110 and insulator 120 are coaxially arranged.Such as, screen 110 is arranged on the madial wall of housing 100.Such as, screen 110 is some first wires.Such as, this first wire is Gas in Ultra-thin Metal Wires.Such as, close-packed arrays between each first wire.Such as, some first metal wire knitted are arranged at screen 110.Such as, some first wires are wound around and are arranged at screen 110.In order to reach shield effectiveness better, such as, non-parallel setting between the first wire.Such as, some first wire close-packed arrays circlewise and wrap up screen 110, insulator 120 and contact 130.Wherein in an embodiment, screen 110 comprises aluminium foil and thermoplastic elastomer (TPE), and aluminium foil is arranged at the side near insulator 120, and thermoplastic elastomer (TPE) is arranged at the side away from insulator 120, further, aluminium foil abuts with thermoplastic elastomer (TPE) and bearing of trend is identical.It should be noted that, the first quantity wiry is determined by the diameter of housing 100.Such as, when the diameter of housing 100 is larger, the first wire quantity also corresponding increase of needs.So, under the first effect wiry, prevent the interference of the electromagnetic fields such as external electromagnetic waves, namely shield external environment condition, the interfere information that after the socket particularly coordinated with aviation plug is connected, equipment sends is to the interference of contact 130.
In order to improve the air-tightness of aviation plug further, wherein in an embodiment, housing 100 is provided with sealant, and sealant is arranged at one end of the housing 100 away from resilient coating 101, and sealant abuts with insulator 120 and is rotatably connected.Such as, sealant fully abuts with housing 100.Such as, the side that housing 100 is relative with sealant offers annular groove, the hierarchy structure of annular groove and the thickness matching of described sealant, to make in the outer peripheral edges embedded rings connected in star of sealant.So, under the sealing function of sealant and insulator 120, effectively improve the air-tightness of aviation plug.
The utility model has the advantage of: exterior object can be avoided to contact with the insulator of enclosure interior, some contacts and the direct of electric conductor by housing, the vibration proof performance of aviation connect-disconnect plug is effectively improve under the effect of resilient coating, and, the air-tightness of aviation connect-disconnect plug is improve under the effect of insulator and sealant, and, screen can effectively prevent the electromagnetic interference of the electromagnetic fields such as external electromagnetic waves to contact, thus improves the useful life of aviation connect-disconnect plug on the whole.
Each technical characteristic of the above embodiment can combine arbitrarily, for making description succinct, the all possible combination of each technical characteristic in above-described embodiment is not all described, but, as long as the combination of these technical characteristics does not exist contradiction, be all considered to be the scope that this specification is recorded.
The above embodiment only have expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to utility model patent scope.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
