Abstract

The utility model relates to a rail-mounted terminal block which mainly comprises a plastic main body, a spring leaf and a terminal; and the spring leaf and the terminal are combined together by adopting a multiple insertion-buckling structure, so that both the spring leaf and the terminal do not deviate left and right and up and down and positioned on the plastic body simultaneously. The terminal is grounded for electric conduction in design, the spring leaf is propped against the track, the extremely excellent positioning and conducting effects are achieved under the action of overlapping, and meanwhile, the rail-mounted terminal block also has the characteristic of easiness in operation.

Description

The rail mounted terminal board

Technical field

The utility model is a kind of rail mounted terminal board, refers to that especially a kind of movable group is located at the terminal board of track, with terminal and the shell fragment redesign and the skilful meaning overlap joint of inside, can take into account the quality of conduction and the steadiness of buckle.

Background technology

The rail mounted terminal board mainly be a kind of be an electrode with track, simultaneously the movable group of terminal board is established thereon, utilize inner terminal and shell fragment with buckle and be connected to the terminal board of track, owing to several connatural terminal board groups can be located on the same track, except not taking up space, also conveniently do simultaneously the design of distribution, therefore use very extensive.

Existing terminal board, mainly be provided with a plastic casing, the inside of this plastic casing is provided with the terminal of conduction, this terminal can contact with track, but this plastic casing and interorbital location, then be that to support with the lock of laterally disposed screw be method, this method not only makes the thread of plastic casing be damaged easily, also scratch raceway surface easily simultaneously when the location, need revolve screw lock or outwards winding, cause the time of locking longer, if and the place of and limited space more at distribution, will cause locking not exclusively, be its main shortcoming.

Another kind of existing rail mounted terminal board, structure for so-called Phoenix, mainly be provided with a plastic casing, the inside of this plastic casing is except being provided with the terminal of conduction, and be provided with the metal displacer fastener that tool bends in this plastic casing bottom simultaneously, this metal displacer fastener contacts with track with flexure plane, reaches the effect of conduction on the one hand, has snap-on power on the other hand again; But this existing design, because this metal displacer fastener is to contact with track with the arc body that bends, therefore the conductive area of contact is less, so very easy generation conduction is incomplete, also wearing and tearing easily simultaneously, in assembling, take a lot of work and and terminal between all be to be support with the plastics in the housing and intermetallic inlay card, so the mould needs are more accurate, make and more take a lot of work, cost is higher to be its shortcoming.

The utility model content

Main purpose of the present utility model, mainly be provided with the body of plastics, and the shell fragment of metal and terminal, wherein shell fragment and terminal are with multiple cladding embedding-and-buckling-structured combining, make the two unlikely left and right, upper and lower skew, and be positioned on the plastic body simultaneously, the utility model is finished the ground connection conduction with terminal again in design, and finish pushing against of track by shell fragment, under the effect of overlapping friendship phase, obtain extremely good location and conductive effect, processing ease is characteristic of the present utility model simultaneously.

For making the purpose that reaches above-mentioned, the utility model can following mode be reached:

If a plastic body is provided with a jack at least, and respectively is provided with a side hook in two bottom sides in the end, and be provided with a reference column in bottom center slightly, and at least one grab; Other establishes a shell fragment, and Yu Yiduan is provided with outstanding coak, and end then is provided with the profile of a bending in addition, and this profile protrudes outwards to sketch the contours and forms one " L " shape, and this profile is provided with a protuberance in the inboard; Push against bar and below profile, convex with one; This shell fragment is provided with axis hole and at least one location hole; Establish a terminal again, it has a transverse sheet, these transverse sheet two ends are respectively equipped with pawl, and this transverse sheet is provided with mortise with respect to the coak of shell fragment, and transverse sheet central authorities one side is provided with catch in for erectting to turn up, and catch is provided with a Kong Zhu who protrudes in this, and is provided with at least one lug at middle catch end, and match with square box, stretch in the jack that places plastic body.

Wherein, the grab on this plastic body is two, and is located at the both sides of reference column respectively.

Wherein, the pawl of transverse sheet one end of this terminal is provided with location notch.

Wherein, this shell fragment is horizontally set at the bottom of plastic body.

The beneficial effects of the utility model: when the utility model is established in group, the Kong Zhu of this terminal passes the axis hole of shell fragment, together be set on the reference column of plastic body again, this design will make the terminal of metal and shell fragment obtain good binding and stability, this moment, plastic body then placed the location hole that is positioned shell fragment with grab, and made shell fragment being positioned on the plastic body steadily; And the transverse sheet of terminal is located at the below of shell fragment, and the coak of this shell fragment is positioned the mortise of transverse sheet, and this makes terminal and shell fragment obtain more certain effect that links closely; Simultaneously profile is installed with the location notch place in the transverse sheet end, can avoid the left and right swing of shell fragment at the terminal place, and pushing and pressing bar then elasticity presses on the transverse sheet end face of terminal.

Therefore, when the cross section is that flat " U " shape track groups is when establishing, be to be embedded in respectively between the side hook of plastic body two bottom sides with both sides, simultaneously, the profile of this shell fragment one end is fixed in track with the inside button tightly of protuberance, simultaneously, is compressed the transverse sheet of terminal downwards by the pushing and pressing bar of shell fragment, conduct electricity and transverse sheet and interorbital are contacted with face, can obtain better conductive effect.
