[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example:

[0026] Combined with appendix Figure 1-5 As shown, an injection-molded connector includes: a connector pinhole, an injection-molded connector housing 3, and an insulating cap 2. The connector pinhole is inserted into the injection-molded connector housing 3. One end of the insulating cap 2 is disposed inside the pinhole of the connector pinhole, and the other end is turned outward and sleeved on the sealing bracket of the connector pinhole.

[0027] The connector pinhole includes: a connector pinhole conductive surface 101, a molding encapsulation plane 102 and an encapsulation mounting platform 103 located outside the connector pinhole head, a connector pinhole conductive surface 104 located outside the connector pinhole tail, and a molding positioning plane 105 located at the end of the connector pinhole conductive surface 104; and a pinhole for mounting an insulating cap 2 is formed inside the connector pinhole head.

[0028] Specifically, the connector pinhole has a connector pinhole conductive surface 101, a plastic sealing surface 102, and a sealing mounting platform 103, which are made by lathe machining of hollow custom tube 1; a connector pinhole conductive surface 104 obtained by flattening process; and a plastic sealing positioning surface 105 located at the end of the connector pinhole conductive surface 104.

[0029] The connector pinhole is inserted into the injection-molded connector housing 3. One end of the connector pinhole conductive surface 104 passes through the injection-molded connector housing 3. The plastic sealing plane 102 is flush with the step inside the injection-molded connector housing 3. The insulating cap 2 is plastic sealed on the inner wall of the connector pinhole and is turned outward and sleeved on the outer side of the sealing platform 103 of the connector pinhole. The outer wall of the insulating cap 2 is flush with the connector pinhole conductive surface 101. There is a spacer cavity between the connector pinhole conductive surface 101 and the injection-molded connector housing 3. The spacer cavity 302 is used for plug insertion.

[0030] Furthermore, a through hole or threaded hole is formed on the conductive surface 104 of the connector pinhole as a connection hole 106, used to lock the copper busbar or terminal block. Power can only be supplied after locking. An annular sealing ring mounting groove 301 is formed on the middle end face of the injection molded connector housing 3 for installing the sealing ring to achieve waterproof installation at the interface.

[0031] The specific manufacturing method of this injection-molded connector is as follows:

[0032] (1) Select custom tubing 1 and use lathe processing to obtain the connector pinhole conductive surface 101, which ensures the surface dimensional accuracy and roughness, and at the same time obtains the plastic sealing surface 102.

[0033] (2) The connector pinhole head is machined by lathe to obtain a sealing bracket 103 that matches the insulating cap 2.

[0034] (3) Cut the required tube length for connector pin hole processing. Selectively evaluate whether the inner hole needs mechanical drilling based on the required flat width, and then use a simple flattening tool to obtain the conductive surface 104 of the connector pin hole, while obtaining the plastic sealing positioning plane 105.

[0035] (4) After the connector pinhole is electroplated, it is placed into the injection mold for injection molding. The connector pinhole and the injection molded connector shell 3 form a whole, and are simultaneously encapsulated to obtain the insulating cap 2.

[0036] This invention utilizes a hollow, custom-made tube, machined on a lathe and flattened, to create the connector pinhole. The inner and outer diameters of the custom tube are determined after comprehensive evaluation of conductivity and current-carrying requirements, as well as other structural machining needs. Depending on functional requirements, some surfaces of the custom tube do not require machining, while others, although requiring machining, have minimal machining allowance compared to copper rods. The pinhole flattening is achieved through simple flattening tooling based on mechanical drilling of the inner hole, eliminating the need for complex equipment and molds, mechanical cutting, and waste. Because the flattening is achieved through flattening, the outer diameter of the tube is also reduced compared to copper rod machining. After machining the insulating cap and sealing bracket at the head of the connector pinhole, it is placed in an injection mold for injection molding. Due to the change in cross-section, the connector pinhole naturally possesses anti-rotation and positioning properties, eliminating the need for additional structural designs to achieve these functions. The insulating cap is also injection molded together, resulting in fewer parts in the connector product. Considering all these factors, this connector pinhole machining method and injection molding implementation reduce overall manufacturing costs.

[0037] Although the present invention has been described herein with reference to illustrative embodiments, the above embodiments are merely preferred embodiments of the present invention, and the implementation of the present invention is not limited to the above embodiments. It should be understood that those skilled in the art can design many other modifications and implementations, which will fall within the scope and spirit of the principles disclosed in this application.
