Abstract
The invention discloses a conductive nut for leading out ground protection of a construction machinery instrument, and aims to provide an electrical connector which can not only achieve electric connection but also perform a plugging function. The conductive nut comprises a nut body, wherein two threaded blind holes are respectively formed in two end surfaces of the nut body; at least one annular groove (2) is formed in the surface of the nut body (1). The conductive nut is embedded into the instrument casing through injection moulding, so that an electronic element requiring ground protection can be led out of the insulated instrument casing through screws; the conductive nut is not only simple and convenient in assembly but also strict and reliable in sealing; and the conductive nut is an electrical connector used for leading the ground protection end of the construction machinery instrument out of the instrument casing for achieving ground protection.
Description
Technical field
The present invention relates to a kind of electrical connector, relate in particular to and a kind ofly not only can realize being electrically connected to, but also have the conduction nut of plugging action.
Background technique:As everyone knows, the engineering mechanical instruments working environment is more abominable, not only must have the dustproof and waterproof function; For fear of electromagnetic interference, also must carry out to the electronic component of its inside ground fault protection and process.Yet the engineering mechanical instruments shell is generally plastic shell, therefore the ground fault protection end of internal electronic element should be drawn the sealability that is grounded protection, guarantees again plastic shell from plastic shell, and both are difficult to take into account.Adopt at present usually seal ring or seal in the mode of wire extraction location perfusion sealer, not only assembling and keep in repair cumbersome, and sealing reliability is relatively poor.
Summary of the invention:In order to overcome the defective that exists in prior art, the present invention aims to provide and a kind ofly not only can realize being electrically connected to, but also the engineering mechanical instruments ground fault protection with plugging action draw with the conduction nut.
To achieve these goals, the present invention by the following technical solutions: it comprises nut body; The both ends of the surface of nut body respectively are provided with a tapped blind hole.
The surface of nut body is provided with at least one circular groove.
Compared with the prior art, the present invention is owing to having adopted technique scheme, both ends of the surface at nut body are provided with respectively tapped blind hole, therefore only need this nut body to be embedded on the shell wall of meter housing by the mode of injection moulding, can needs be carried out by screw the electronic component of ground fault protection and draw from the meter housing of insulation; Not only assemble simple and conveniently, and sealing is tight reliable.
Description of drawings:
Fig. 1 is structural representation of the present invention;
Fig. 2 is the schematic diagram that the present invention is applied to engineering mechanical instruments.
In figure: nut body 1 circular groove 2 sheet metal 3 screw 4 first ground fault protection element 5 meter housing 6 liquid crystal display panel 7 indicator window 8 second ground fault protection element 9 conductive pole 10 the 3rd ground fault protection elements 11
Embodiment:The invention will be further described below in conjunction with accompanying drawing and specific embodiment:
As shown in Fig. 1～2: the nut body 1 that both ends of the surface respectively are provided with tapped blind hole is embedded on meter housing 6 by the mode of injection moulding, is fixed with indicator window 8 on this meter housing; Being fixed with liquid crystal display panel 7 and the first ground fault protection element 5 of connecting by conductive pole 11 respectively, the second ground fault protection element 9, the 3rd ground fault protection element 10 etc. in meter housing 6 needs the electronic component of ground fault protection; the 3rd ground fault protection element 10 is electrically connected to this nut body by the screw 4 that is fixed in nut body 1 left side tapped blind hole, is arranged in meter housing 6 surface and the sheet metal 3 that is electrically connected to engineering machinery rack earth end (not shown) is electrically connected to this nut body by being fixed on the other screw 4 of nut body 1 right side tapped blind hole.
Loosening for fear of nut body 1, simultaneously also in order to strengthen sealing, the surface of nut body 1 is provided with circular groove 2.
Claims (2)
1. an engineering mechanical instruments ground fault protection is drawn with the conduction nut, comprises nut body; It is characterized in that: the both ends of the surface of nut body (1) respectively are provided with a tapped blind hole.
2. engineering mechanical instruments ground fault protection according to claim 1 is drawn with the conduction nut, and be characterised in that: the surface of nut body (1) is provided with at least one circular groove (2).
