Description
Technical field
The utility model relates to distribution terminal grounding technology field, is specifically related to a kind of bell-type distribution terminal and electrically assembles earthing device.
Background technology
Hood configuration is as the common a kind of version of distribution terminal, and its inner space is often very narrow and small, and components and parts, connector are relatively intensive.When adopting traditional earthing mode to assemble, each ground connection component Earthing Reliability needs to depend on other parts, usually there will be cabling difficulty, the phenomenons such as imperfect earth; Moreover, traditional wired mode is realized by wire interconnection, because the spatial limitation diameter of wire can not be too large, causes often stray inductance larger, comprise antenna impedance in the electromagnetic compatibility project testing of a large amount of high-frequency interferencing signal suddenly to increase at static discharge, Clusters etc., cause ground connection failure.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of convenient installation and possesses the bell-type distribution terminal ground connection installation component of good earth performance.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of bell-type distribution terminal electrically assembles earthing device, mainly comprise cover plate, support on the cover board and earth terminal are installed, it is characterized in that, described cover plate is provided with some for being connected with outer member and being embedded with the installing hole of metalwork, ground strip is provided with inside described cover plate, described ground strip is connected with metalwork and support respectively by connector, and described earth terminal is connected with ground strip.
Further, described metalwork two is provided with internal thread.
Further, described metalwork is concordant with lid surface.
Further, described connector is lock-screw.
Further, be provided with aviation socket outside described cover plate, described aviation socket is fixed on installing hole by lock-screw.
Further, described earth terminal and ground strip are fixed by locking nut inside cover plate.
Further, described ground strip is " work " font structure.
The beneficial effects of the utility model: the utility model adopt this ground connection assembling device achieve earth terminal, ground strip, aviation socket and mounting bracket be connected when assembling product conducting connect, eliminate structural member need carry out ground connection step by wire interconnection, not only reduce wiring quantity, shorten wiring length, and adopt ground strip to instead of electric wire, each ground connection component Earthing Reliability is no longer dependent on other parts, enhances the Earthing Reliability of device; " work " font ground strip has larger surface area and cross-sectional area simultaneously, and dead resistance and stray inductance, much smaller than electric wire, improve the validity of product ground connection under high frequency transient disturbed condition; The components and parts being installed on support also directly can be connected ground connection nearby with mounting bracket.Therefore, so not only can simplify assembling mode, and greatly increase the reliability of distribution terminal grounding connection.
Accompanying drawing explanation
Fig. 1 is the structural representation inside the utility model preferred embodiment cover plate.
Fig. 2 is the structural representation outside the utility model preferred embodiment cover plate.
Fig. 3 is the metalwork cross-sectional schematic of the utility model preferred embodiment.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
With reference to Fig. 1, Fig. 2 and Fig. 3, a kind of bell-type distribution terminal electrically assembles earthing device, mainly comprises cover plate 1, support 2, ground strip 6, earth terminal 3 and aviation socket 8.Described support 2 is arranged on cover plate 1, described cover plate 1 is provided with installing hole 5, is inlaid with metalwork 4 in described installing hole 5, described ground strip 6 is connected with metalwork 4 and support 2 respectively by connector 7, described earth terminal 3 is connected with ground strip 6, and described aviation socket 8 is arranged on outside cover plate 1.
Preferably, all there is internal thread at described metalwork 4 two, also can be metalwork 4 inner surface is all internal thread; Now connector 7 selects the screw thread of lock-screw and metalwork 4 to be used in combination.
In addition, only can need arrange through hole inside described metalwork 4, now connector 7 is selected to be mated use with the screw of nut.
Preferably, described ground strip 6 adopts " work " font structure, also can adopt the structure that other can be connected with support 2 and all installing holes 5.
Particularly, in the present embodiment, described cover plate 1 is reserved with the installing hole 5 that manhole is used as aviation socket 8 and earth terminal 3, be inlaid with two in described installing hole 5 and all have internal thread metalwork 4, the position of described metalwork 4 is corresponding with aviation socket 8 fixing hole, and the surface of metalwork 4 is concordant with cover plate 1.Described ground strip 6 is reserved with the circular hole corresponding with installing hole 5, is connected inside cover plate 1 by lock-screw 6 with metalwork 4, so just achieves ground strip 6 and is connected conducting with metalwork 4; Described aviation socket 8 is fixed on the installing hole 5 outside cover plate 1 by lock-screw 6, realizes the connection conducting of aviation socket 8 and metalwork 4; Described support 2, as the main installation strutting piece of product, is connected with ground strip 6 inside cover plate 1 by lock-screw 6, realizes support 2 and is connected conducting with ground strip 6; Described earth terminal 3 is arranged on the installing hole 5 also through cover plate outside cover plate 1, is connected and fixed, is grounded the connection conducting of sheet 6 and earth terminal 3 by locking nut 9 and ground strip 6.In sum, just can realize support 2 by connecting above, ground strip 6, metalwork 4, aviation socket 8 be connected with the mutual conduction of earth terminal 3, without the need to being connected the ground connection nearby that can realize relevant components and parts on support 2 by wire, be grounded terminal 3 effectively to external ground.
