Abstract
The utility model relates to a universal grounding-wire spring pawl for a 10 kV switch cabinet bus. The universal grounding-wire spring pawl comprises a clamping pawl and a joint coaxially connected with the pawl, wherein the clamping pawl comprises a cylindrical base and at least two contact sheets, the contact sheets are fixed one of end faces of the base and are parallel with an axis of the base, and the joint is connected with the other end face of the base coaxially and fixedly. An upper end of the contact sheets is connected with the base. A head segment is from the upper end to a central part of the contact sheets. Thickness of the head segment is 4-6 mm. A tail segment is from the central part to a lower end of the contact sheets. Thickness of the tail segment gradually increases from the central part to the lower end. Thickness of the lower end is 12-14 mm. The beneficial effects of the spring pawl provided by the utility model are that the spring pawl is relatively thick and is directly fixed on the base, intensity of the spring pawl is greatly raised, intensity and service life of moving contacts are raised, and stable and smooth performance of a circuit is guaranteed.
Description
Technical field
the utility model relates to a kind of universal earth connection spring detent for the 10kV switch cabinet bus.
Background technology
as shown in Figure 1, it comprises latch handle 21, the spring detent be connected with latch handle 21 existing earth connection contact, each spring detent comprises multi-disc spring leaf 22, every flat spring sheet 22 is " several " type, because spring leaf 22 is thinner and superpose and form spring detent by multi-disc, be easy to can shine into damage to spring leaf in plug repeatedly, bring useful life shorter, connect the shortcomings such as unstable.
The utility model content
the purpose of this utility model is to provide a kind of universal earth connection moving contact for the 10kV switch cabinet bus.
for solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of universal earth connection spring detent for the 10kV switch cabinet bus, it comprises claw, with the coaxial connector be connected of described claw, described claw comprises columniform base, on at least two one of them end faces that is fixed in described base and the contact paralleled with the axis of base, described connector is coaxial with another end face of base and be fixedly connected with, described contact upper end is connected with base, section headed by its upper end to middle part, the thickness of described first section is 4～6mm, its middle part is rear to lower end, the thickness of described rear is increased gradually by middle part to lower end, the thickness of lower end is 12～14mm.
optimize, described contact, base and connector are one-body molded.
optimize, described contact has 6～8, and all described contact circular array are distributed on end face, and the lateral surface of described contact flushes with the side of described base.
optimize, the external diameter of the circle that the lower end of described contact surrounds is 70～80mm.
the beneficial effects of the utility model are: spring detent of the present utility model is thicker and directly be fixed on base, has greatly improved the intensity of spring detent, thereby has improved intensity and the useful life of moving contact, has guaranteed that stablizing of circuit is unimpeded.
The accompanying drawing explanation
accompanying drawing 1 is the three-dimensional view of existing spring detent;
the three-dimensional view that accompanying drawing 2 is spring detent of the present utility model;
in accompanying drawing: 1, spring detent; 11, claw; 12, connector; 111, base; 112, contact.
Embodiment
below in conjunction with embodiment shown in the drawings, the utility model is described in detail below:
as shown in Figure 2, should for universal earth connection spring detent of 10kV switch cabinet bus comprise claw 11, with the coaxial connector be connected 12 of claw 11.Claw 11 comprises that columniform base 111, at least two are fixed in contact 112 on one of them end face of described base 111, and in the present embodiment, contact 112 has 8.The bearing of trend of the length of each contact 112 parallels with the axis of base 111, all contacts 112 circular array centered by the center of circle of the end face of base 111 is distributed on this end face, the upper end of each contact 112 is connected with base 111, section headed by its upper end to middle part, its middle part is rear to lower end, the thickness of first section is 4～6mm, the thickness of rear is increased gradually by middle part to lower end, the thickness of lower end is 12～14mm, in the present embodiment, the thickness of first section is got 5m, and the thickness of lower end is got 13mm.Lateral surface flushes with the side of base 111, and the external diameter of the circle that therefore described contact 112 surrounds is 76mm.
connector 12 coaxially is connected with another end face of base 111, and for further improving the intensity of spring detent, contact 112, base 111 and connector 12 are one-body molded.
above-described embodiment is only explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection range of the present utility model with this.All equivalences of doing according to the utility model spirit change or modify, within all should being encompassed in protection range of the present utility model.
