Abstract

The utility model relates to a connecting terminal. The utility model comprises a wire frame; the middle part of the wire frame is provided with a through hole for the interpenetration of electric wires; a wire pressing plate is inserted in the wire frame; a fastening screw is arranged on the top of the wire frame; the upper part of the cross section of the through hole forms a regular square shape, and the lower part forms a circular arc shape; the connecting part of the square shape and the circular arc shape are provided with a chamfer; the lower surface of the wire pressing plate is provided with salient points to further fasten pressed electric wires. In view of the defect of infirm clamp when the existing connecting terminal clamps electric wires with different specifications, the utility model mainly change the direct connection of the original circular arc shape and the regular square shape of the cross section of the through hole of the wire frame to that the connecting part of the circular arc shape and the regular square shape is additionally provided with a chamfer; the lower surface of the wire pressing plate is provided with a plurality of salient points to be simultaneously connected with the electric wires with different specifications, and the pressed electric wires are firmer.

Description

A kind of binding post

Technical field

The utility model belongs to and is electrically connected the device field, relates in particular to a kind of binding post.

Background technology

In the electrical fitting field, the binding post kind that is used to connect two different electric wires is also a lot, implementation is also different, but more or less all there is certain defective, as accompanying drawing 1 is the structural representation of Chinese ZL03225654.X patent disclosed a kind of " combined socket and switch binding post ", it also is a kind of binding post more common during we live, mainly by wire frame 1, the tension disc 2 and the screw 3 that are installed in the wire frame are formed, this structure can the electric wire below the tension disc be fixed in the wire frame in wire frame with interting by the fastening of screw, but but there are some shortcomings, there is a big chamfering 11 as the wire frame interstitial hole, when two bigger electric wires insert, causing wherein easily, a wire can not directly contact with tension disc, but it is directly fixing by another wire, and the lower surface that its tension disc contacts with electric wire is more smooth, can not be well and the electric wire interlock, and tension disc is difficult to touch when the electric wire that inserts is thin or multi cord, and there is the not firm weak point of solidus equally in this binding post.Accompanying drawing 2 has been shown another similar binding post in addition, and the lower part that the difference of its above-mentioned binding post is mainly the wire frame interstitial hole changes circular arc into, and this structure exists interlock not firm equally, the shortcoming of loose contact.

The utility model content

The purpose of this utility model provides the binding post that a kind of suitable all size electric wire connects, is connected firmly.

Requirement in order to achieve the above object, the utility model adopt following scheme to realize:

A kind of binding post, comprise wire frame, the centre is provided with the through hole of an interspersed electric wire, in wire frame, assigned a tension disc, at the wire frame top one trip bolt is installed, the top, cross section of described through hole is regular square, and the bottom is a circular arc, and square and junction, circular arc two place is provided with and is chamfering; Described tension disc lower surface is provided with salient point, can further fastening institute piezoelectricity line.

Binding post described in the utility model, the salient point on the tension disc lower surface can be 2 to 8.

As further improvement of these options, above-mentioned tension disc can be made up of mutually perpendicular two parts, a part is interspersed in the tension disc through hole, another part is perpendicular to outside the through hole, its surface has an aperture, whole binding post can be fixed on other objects by aperture, also can connect outside line.

As further improvement to such scheme, can the screens that width is slightly larger than the through hole transverse width be set in the termination that above-mentioned tension disc is interspersed in the through hole part, screens can prevent that wire frame and tension disc are separated.

The utility model is primarily aimed at and fixes not firm deficiency when existing binding post fixes the different size electric wire, wire frame through hole cross sectional shape directly is connected by original circular arc and regular square changes to circular arc and regular square junction and increase chamfering, and be provided with a plurality of salient points at the tension disc lower surface, the electric wire that can connect different size simultaneously, and the electric wire of being pressed is more firm.

Description of drawings

Accompanying drawing 1 is a kind of structural representation of existing binding post; Accompanying drawing 2 is the structural representation of another kind of existing terminal; Accompanying drawing 3 is the utility model wire frame structural representation; Accompanying drawing 4 is the utility model tension disc structural representation; Accompanying drawing 5 is the utility model overall structure schematic diagram; Accompanying drawing 6 inserts schematic cross-section behind the electric wire for the utility model.

Embodiment

For the ease of understanding, with specific embodiment structural principle of the present utility model is further described in detail below in conjunction with accompanying drawing:

As shown in Figure 3, wire frame 1 is a tubulose, and its top, cross section is regular square, and the bottom is the great circle arc, and chamfering 11 is arranged in circular arc and square junction, is provided with a screw hole on wire frame top, is used for trip bolt and screws in.Again as shown in Figure 4, tension disc 2 integral body are L shaped, one end surfaces is provided with an aperture 22, aperture 22 is used for tension disc is fixed on other objects, simultaneously also can directly connect external cable, be provided with two salient points 21 on tension disc other end surface, its termination is provided with a screens 23, and screens can prevent that wire frame and tension disc are separated.Again as shown in Figure 5, during installation tension disc being had the salient point end inserts in the wire frame, the screens of its termination is exposed from the wire frame other end, and make salient point surface down, and then trip bolt 3 screwed in from the top, and make it to contact tension disc upper surface in the wire frame, continue to be rotated down that trip bolt can make that tension disc moves downward closely contacts with electric wire to tension disc, add the effect of salient point, electric wire firmly can be stuck in the binding post.By accompanying drawing 6, can clearlyer find out the each several part structure of inserting behind the electric wire.
