Abstract

The invention discloses a terminal which comprises a plastic member and a plurality of copper inserts that are embedded into the plastic member. One end of each copper insert is provided with a threaded hole for connecting with a connecting wire. The plastic member is molded through a mold in an injection molding manner. The plurality of copper inserts are directly placed at corresponding positions in the mold. Fused plastic is injected into the mold and wraps the copper inserts so that the plastic member and the copper inserts are integrally molded, thereby realizing embedding of the copper inserts into the plastic member. The external surface of each copper insert is also provided with a plurality of longitudinal troughs and a plurality of circumferential troughs. In an injection molding process, molten plastic flows into the longitudinal troughs and the circumferential troughs, thereby realizing fixation between the copper inserts and the plastic member. The terminal of the invention has relatively large number of wiring ports. The terminal has advantages of relatively high sealing performance between the copper inserts and the plastic member, high connecting strength and attractive appearance.

Detailed description of the invention

Referring to the accompanying drawing illustrating the embodiment of the present invention, the present invention is described in more detail. But, the present invention can realize in many different forms, and should not be construed as by restriction of the embodiment of proposition at this. On the contrary, it is proposed to these embodiments are to reach fully and complete disclosure, and make those skilled in the art understand the scope of the present invention completely. In these accompanying drawings, for clarity sake, it is possible to be exaggerated size and the relative size in layer and region.

The invention provides a kind of binding post, for the connection of the wiring such as electric field control line, and be provided with multiple connection jaws, present configuration is attractive in appearance, and wiring place watertightness is better.

With reference to Fig. 1-4, binding post includes a working of plastics 1, and working of plastics 1 is in the form of annular discs, and the concrete shape of certain working of plastics 1 sets also dependent on concrete condition, is not limited as herein; Being embedded with several copper inserts 3 on working of plastics 1, copper insert 3 is along the axially arranged of working of plastics 1 and runs through working of plastics 1; Being provided with screwed hole 31 in one end of copper insert 3, wiring can be tightened in screwed hole 31 either directly through threaded mode, connects quick and convenient.

In the present embodiment, two circle copper inserts it are provided with around the center of circle of working of plastics 1, often circle copper insert is provided with several copper inserts 3 uniformly arranged, and setting straggly between adjacent copper insert between two circle copper inserts, namely two circle copper inserts in copper inserts be not at same diametrically, as shown in Figure 2; The present invention arranges copper insert by the way so that can arrange more connection jaws on working of plastics 1, and make will not interfere between adjacent connection jaws, not affect normal operation.

In the present embodiment, the center position of one end end face that working of plastics 1 is connected with wiring is provided with cross bossing 2, and being provided with of cross bossing 2 is beneficial to the intensity strengthening binding post;Copper insert 3 can be provided with, as shown in Figure 2 in four rectangular area of cross bossing 2.

In the present embodiment, working of plastics 1 adopts the injection molding, the constituent of working of plastics 1 to be: the PA66(nylon66 fiber of 68.9%), the PA6(nylon 6 of 4%), the GF(glass fibre of 23.1%), the breeze of 4%; In prior art, the working of plastics of binding post is generally made only with PA66, and cast gate place (in the present invention, the Jiao Kou of working of plastics 1 is positioned on cross bossing 2) corresponding on the working of plastics centre position made is easy to black speck and folder water wave etc. occur. PA66 and PA6 is used by the present invention together, and owing to the mobility of PA66 material is not so good, after adding PA6, the mobility of plastic cement well a lot, thus can reduce black speck and the appearance of folder water wave; The present invention has also been mixed into glass fibre and breeze the setting on passing ratio wherein, thus solving cast gate place on working of plastics the problem of black speck occur, solving the problem easily occurring lines, crackle on working of plastics simultaneously, decreasing the appearance of substandard products.

In the present embodiment, working of plastics 1 adopts mold injection molding, and some copper inserts 3 are placed directly within the corresponding position in mould, and the plastics after melted inject in mould and wrap copper insert 3, making working of plastics 1 and copper insert 3 one-body molded, being embedded in working of plastics 1 thus realizing copper insert 3. And, the outer surface of copper insert 3 is additionally provided with some cannelures and some circumferential slots, plastics after melting in injection moulding process are flowed in cannelure and circumferential slot, define the rotation of copper insert 3 movement axial relative to working of plastics 1 and circumference, it is achieved fixing between copper insert and plastic parts.

The present invention by being directly introduced in mould by copper insert 3 in working of plastics injection moulding process so that copper insert 3 and the integrated production method of working of plastics 1, substantially increases the sealing between copper insert 3 and working of plastics 1, improves the performance of binding post; And by the setting of cannelure and circumferential slot, it is ensured that the bonding strength between copper insert and working of plastics, it is therefore prevented that the phenomenon spinned between copper insert 3 and working of plastics 1 time wiring is screwed into screwed hole 31 of copper insert 3.

Because those skilled in the art should be understood that the present invention can be implemented without departing from the spirit or scope of itself with other concrete forms many. Although having been described for the case study on implementation of the present invention, it should be understood that the present invention should not be limited to these embodiments, those skilled in the art can change and modifications as made within the spirit and scope of the present invention that appended claims defines.
