[0026] The technical solutions in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model. Apparently, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.
[0027] Please refer to Figs. 1 to 7 A double-wire threaded connector in the embodiment includes a connector shell 1, a double-end threaded connecting piece 2, a contact 3 and an insulator component 4. The insulator component 4 is located inside the connector shell 1 and is plugged with the connector shell 1. The inner wall of the connector shell 1 is provided with a convex ring. The outer side of the insulator component 4 is provided with a groove matched with the convex ring. The convex ring is clamped into the inside of the groove. The inside of the insulator component 4 is provided with an opening 5. The contact 3 is inserted into the inside of the insulator component 4 through the opening 5. The size of the opening 5 is matched with that of the contact 3. The double-end threaded connecting piece 2 is threadedly connected with the surface of the connector shell 1. The surface of the connector shell 1 is fixedly connected with a snap ring 6. The surface of the snap ring 6 is clamped with a tail wire clamp 7.
[0028] The connector shell 1 is made of aluminum alloy, and a key groove is formed on the connector shell 1. The aluminum alloy has the characteristics of low density, good mechanical properties, good processing performance, non-toxicity, easy recycling, good electrical conductivity, heat conductivity and corrosion resistance. The key groove can prevent misinsertion. The double-thread connecting piece 2 is made of aluminum alloy, and a double-thread is formed on the inner wall. The double-thread has strong wear resistance, because the thread profile is more planar, the contact area after connection is larger, and it can withstand greater tension and shear force. In addition, it is not easy to produce surface plastic deformation when bearing greater load, and it can obtain greater fastening force after tightening, and it is not easy to loosen, and it has good stability and reliability. The double-thread has strong bearing capacity, more threads and small angle, and the formed connecting pair has high bearing capacity and tightness, and can withstand greater static, dynamic load and impact load.
[0029] It should be noted that the biggest difference between single-thread and double-thread is the distance of the wire rotating one circle. The use of double-thread can make the connector connection faster and more reliable.
[0030] In addition, the contact piece 3 is made of copper alloy and is gold-plated on the surface, which ensures high efficiency and low loss of signal transmission. The insulator part 4 is made of polyphenylene sulfide material, and the size of the insulator part 4 is matched with the size of the connector shell 1. The polyphenylene sulfide material is a new type of high-performance thermoplastic resin, which has the advantages of high mechanical strength, high temperature resistance, chemical resistance, flame retardance, good thermal stability and excellent electrical properties, which can ensure that the connector can maintain good working condition in harsh environment.
[0031] The working principle of the above embodiment is as follows:
[0032] When splicing, the insulator part 4 is a plastic thermoplastic resin, which is convenient to apply external force to insert the insulator part 4 into the inside of the connector shell 1, and the convex ring is clamped into the inside of the groove to complete the fixation, which is convenient for splicing. In addition, the insulator part 4 is provided with an opening 5 matched with the contact piece 3, which can ensure that the contact piece 3 is clamped into the inner cavity of the insulator part 4. The insulator part 4 is arranged between the connector shell 1 and the contact piece 3, which effectively prevents accidental leakage of current, and also prevents water and dust. Through the double-thread design of the double-thread connecting piece 2, the connector shell 1 can be connected more quickly. The tail wire clamp 7 is convenient for fixing and connecting the wire, which ensures that the electrical connection between the wire and the connector is stable and reliable.
