Abstract

The utility model relates to a wiring device of a large power heater. The wiring device comprises a copper wire braiding band used for being wound on a wiring column of the large power heater in a single loop mode, a clamping tool used for tightly clamping a winding portion of the copper wire braiding band and a wiring head connected with a tail end of the copper wire braiding band, wherein a surface of the clamping tool is coated with an anti-oxidation metal plating layer. According to the wiring device, the copper wire braiding band is utilized to be in soft connection with the wiring column, so an effective conductive area is relatively large, local oxidation and heating do not easily occur, and service life of the wiring column and production safety are guaranteed; the surface of the clamping tool is coated with the anti-oxidation metal plating layer, so oxidation of the clamping tool is avoided even after long-term use, and service life of the clamping tool is prolonged; a lower end of a screw is provided with a barb, so fastening can be realized through only inserting the screw into a screw hole, and mounting is convenient.

Description

A kind of termination of high-power heater

Technical field

The utility model relates to a kind of for connecting the termination of the power-line terminal of high-power heater.

Background technology

In prior art, the binding post of high-power heater (is generally copper pipe is flattened with the connected mode of the hard contact of normal employing of being connected of power line, and adopt fixture to be fixed on binding post), cause contact area less, contact resistance is larger, easily there is the phenomenon of selective oxidation, heating, thereby affect the useful life of binding post, affect the normal use of high-power heater.

Utility model content

The technical problems to be solved in the utility model is to provide the termination of the large and high-power heater that useful life is longer of a kind of simple in structure, easy for installation, conductive contact area.

For solving the problems of the technologies described above, the termination of the high-power heater that the utility model provides, comprising: the copper wire braid for multi-turn solderless wrapped connection on the binding post of high-power heater, for the fixture that the solderless wrapped connection portion of described copper wire braid is clamped and the connector lug that is connected in proof copper-wire braided end of tape; On the surface of described fixture, connector lug, be coated with the anti-oxidation coat of metal, avoid after long-term use, fixture is oxidized, and lengthened the useful life of fixture.

Described fixture comprises a pair of symmetrically arranged clamping plate, and this front end to clamping plate is hinged, and the central portion of clamping plate is provided with and is suitable for the curved portions that coordinates with the solderless wrapped connection portion of described copper wire braid, and screws clamp is passed through in this rear end to the curved portions of clamping plate.

On the cylinder of binding post and on the medial surface of clamping plate, be distributed with anti-slip veins, in use between described fixture and binding post, be subjected to displacement preventing.

The postmedian of described fixture has to the inside the knuckle portion of extending, so that between the postmedian of fixture and the side of copper wire braid, there is gap during clamp, so that it has elasticity.

The lower end of described screw is provided with a plurality of hangnails, and this hangnail makes screw be fixed on the flexible postmedian of having of described fixture, due to the effect screw difficult drop-off of elastic force, with respect to conventional threads formula locking method, installs more convenient.

The technique effect the utlity model has: in termination of the present utility model, adopt copper wire braid to be connected with binding post is soft, make effective conductive contact area larger, be difficult for occurring the phenomenon of selective oxidation, heating, useful life and the production safety of binding post have been guaranteed, on the surface of fixture, be coated with the anti-oxidation coat of metal, avoid after long-term use, fixture is oxidized, lengthened the useful life of fixture, employing arranges hangnail in the lower end of screw, makes screw only need fill in screw hole and can complete fastening, easy for installation.

Accompanying drawing explanation

For content of the present utility model is more likely to be clearly understood, below the specific embodiment by reference to the accompanying drawings of basis, the utility model is described in further detail, wherein

Fig. 1 is the structural representation of the termination of the heater in embodiment;

Fig. 2 is the vertical view of Fig. 1.

Embodiment

Below in conjunction with drawings and Examples, the utility model is elaborated:

The termination of the high-power heater of the present embodiment comprises: the copper wire braid 1 for multi-turn solderless wrapped connection on the binding post 2 of high-power heater, for the fixture 3 that the solderless wrapped connection portion of described copper wire braid 1 is clamped and the connector lug 4 that is connected in copper wire braid 1 end; On the surface of described fixture 3, connector lug 4, be coated with the anti-oxidation coat of metal, avoid after long-term use, fixture 3 is oxidized, and lengthened the useful life of fixture 3.

Described fixture 3 comprises a pair of symmetrically arranged clamping plate 3-1, this front end to clamping plate 3-1 is hinged, the central portion of clamping plate 3-1 is provided with and is suitable for the curved portions that coordinates with the solderless wrapped connection portion of described copper wire braid 1, and this clamps by screw 5 rear end of the curved portions of clamping plate 3-1.

On the cylinder of binding post 2 and on the medial surface of clamping plate 3-1, be distributed with anti-slip veins, in use between described fixture 3 and binding post 2, be subjected to displacement preventing.

The postmedian of described fixture 3 has to the inside the knuckle portion of extending, so that fixture 3 has gap between the postmedian of fixture 3 and the side of copper wire braid 1 while clamping, so that it has elasticity.

The lower end of described screw 5 is provided with a plurality of hangnails, and this hangnail makes screw 5 be fixed on the flexible postmedian of having of described fixture 3, due to effect screw 5 difficult drop-offs of elastic force, with respect to conventional threads formula locking method, installs more convenient.

Obviously, above-described embodiment is only for the utility model example is clearly described, and is not the restriction to execution mode of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all execution modes.And these belong to apparent variation that spirit of the present utility model extended out or change still among protection range of the present utility model.
