Abstract
The utility model relates to a terminal for foundry goods heater. It includes casing, electrothermal tube outer wall and terminal, its characterized in that, and still including the insulating dustcoat that overlaps and be used for drawing forth the terminal and add thick terminal, electrothermal tube outer wall and casing looks rigid coupling, insulating cover suit just lies in between electrothermal tube outer wall and the dustcoat on the terminal, the dustcoat includes with thick portion and connecting portion, the diameter that adds thick portion is greater than the diameter of terminal, and is equipped with the screw thread on the lateral wall with thick portion, the internal thread hole that matches rightly with wiring column diameter is seted up to the dustcoat in connecting portion one end, the dustcoat passes through connecting portion fixed mounting on the terminal. It draws forth and enlarges the size of original terminal through the dustcoat under the unchangeable condition of the processing technology of original foundry goods for easy maintenance, cost reduction, wiring, use be safe and reliable more, and has prolonged the life of terminal.
Description
Technical field
The utility model relates to a kind of binding post for casting heater.
Background technology
Traditional casting heater mode of connection mostly adopts and is welded on the original binding post of foundry goods by binding post, reaches the object of drawing binding post; Although this mode of connection is convenient, there is very large defect, first, easily occur dry joint, weld problem not in place, cannot welding quality be detected simultaneously; Secondly, binding post is when being energized, and easily produce spark, cause binding post to be burned, user cannot keep in repair, and need change integral heater, maintenance cost is high; Finally, by the restriction of processing technology and foundry goods itself, the size of the original binding post of foundry goods can not expand, and original binding post can not bear big current; Factors causes the demand that cannot meet user useful life of the original binding post of foundry goods.
Utility model content
The utility model is intended to solve the problem, provide a kind of binding post for casting heater, it is when the processing technology of original foundry goods is constant, drawn by outer cover and expand the size of original binding post, make easy to maintenance, cost reduces, and wiring, use procedure are more safe and reliable, and extend the useful life of binding post and foundry goods, its technical scheme adopted is as follows:
A kind of binding post for casting heater, comprise housing, electrothermal tube outer wall and binding post, it is characterized in that, also comprise insulating case and for drawing binding post and the outer cover of overstriking binding post, described electrothermal tube outer wall and housing Joint, described insulating case is set on binding post, and between electrothermal tube outer wall and outer cover; Described outer cover comprises overstriking portion and connecting portion, and the diameter in described overstriking portion is greater than the diameter of binding post, and the lateral wall in overstriking portion is provided with screw thread; Described outer connecting portion one end that covers on offers the internal thread hole suitable with binding post diameter compatible, and described outer cover is fixedly installed on binding post by connecting portion.
On the basis of technique scheme, described outer cover also comprises location division, and it is positioned at the junction of overstriking portion and connecting portion.
On the basis of technique scheme, described binding post is connected with external power source by wire, and described wire is wrapped in overstriking portion, and is fixed by nut screwing clamping.
On the basis of technique scheme, be set with pad between described wire and nut, described wire is between pad and location division.
The utility model tool has the following advantages: it is when the processing technology of original foundry goods is constant, drawn by outer cover and expand the size of original binding post, making easy to maintenance, cost reduces, wiring, use procedure are more safe and reliable, and extend the useful life of binding post and foundry goods.
Accompanying drawing explanation
Fig. 1: structural representation of the present utility model;
Fig. 2: the schematic diagram that outer cover described in the utility model matches with binding post;
Fig. 3: the cutaway view of outer cover described in the utility model;
Embodiment
Below in conjunction with accompanying drawing and example, the utility model is described in further detail:
As shown in Figure 1 to Figure 3, a kind of binding post for casting heater of the present embodiment, comprise housing 1, electrothermal tube outer wall 2 and binding post 3, also comprise insulating case 4 and the outer cover 5 for drawing binding post 3 overstriking binding post 3, described electrothermal tube outer wall 2 and housing 1 Joint, described insulating case 4 is set on binding post 3, and between electrothermal tube outer wall 2 and outer cover 5; Described outer cover 5 comprises overstriking portion 51 and connecting portion 53, and the diameter in described overstriking portion 51 is greater than the diameter of binding post 3, and the lateral wall in overstriking portion 51 is provided with screw thread; Described outer cover 5 offers the internal thread hole 53-1 suitable with binding post 3 diameter compatible in connecting portion 53 one end, described outer cover 5 is fixedly installed on binding post 3 by connecting portion 53.
Preferably, the lateral wall of described connecting portion is hexagon, is convenient to user and screws.
Preferably, described outer cover 5 also comprises location division 52, and it is positioned at the junction of overstriking portion 51 and connecting portion 53.
Preferably, described binding post 3 is connected with external power source by wire, and described wire is wrapped in overstriking portion 51, and tightens fixing by nut 6.
Further, be set with pad 7 between described wire and nut 6, described wire is between pad 7 and location division 52.
Described binding post 3 is also set with packing ring 8, and it, between insulating case 4 and outer cover 5, its object is to, prevent insulating case 4 from directly contacting with outer cover 5, in outer cover 5 rundown process, need to compress insulating case 4, easily cause compressing insulating case 4 discontinuity, loss is serious.
Be illustrated the utility model by way of example above, but the utility model is not limited to above-mentioned specific embodiment, all any changes of doing based on the utility model or modification all belong to the claimed scope of the utility model.
