Abstract
Description
Technical Field
[0001] This utility model belongs to the field of power plug technology, and in particular relates to a power plug inner frame that facilitates wiring. Background Technology
[0002] Traditional power plug internal frames typically use connecting nuts or crimping to secure the power cord cores, resulting in low wiring efficiency, complex operation, and susceptibility to poor soldering or contact. Especially in applications requiring frequent wiring or cable replacement, traditional structures struggle to meet the demands for quick and reliable connections. Furthermore, existing plug internal frame structures offer only a single method of securing the cord cores, lacking effective mechanical locking and anti-loosening designs, thus impacting safety and stability during use. Summary of the Invention
[0003] The purpose of this utility model is to provide a power plug inner frame that facilitates wiring, so as to solve the problems of inconvenient wiring and unreliable fixation in the prior art.
[0004] This utility model achieves the above-mentioned objective through the following technical solution: it includes a pair of metal contacts and a pin insulator. The metal contacts are divided into a male contact and a female contact, which are respectively inserted into both ends of the pin insulator. The top of the metal contacts extends to form a connector. A clamp is provided on the outside of the connector, and the clamp and the connector clamp the power wire core.
[0005] Furthermore, the outer surface of the connector is provided with a wire groove, and the clamp is also provided with the wire groove, and the two wire grooves are positioned opposite each other to form a threading hole.
[0006] Furthermore, a square hole is provided through the connector.
[0007] Furthermore, a connecting plate is bent on one side of the clamping plate, and a limiting rod is provided at the other end of the connecting plate. The edges of the limiting rod on the side are all rounded. The clamping plate, the connecting plate, and the limiting rod are an integral structure.
[0008] Furthermore, the width of the connecting plate does not exceed the width of the square hole, the length of the limiting rod is not less than the width of the square hole and less than the height of the square hole, and the connecting plate and the limiting rod are vertically inserted into the square hole and then flipped to form a limiting position.
[0009] Furthermore, the clamp plate is locked to the upper end of the connector by a screw, which is located on the side of the thread hole.
[0010] Beneficial effects: This utility model is reasonably designed and has the following beneficial effects: 1. In this utility model, the power wire core is quickly positioned by the wire groove alignment design, eliminating the need for precise wire length cutting. Combined with the pre-limiting structure, the wiring process is reduced from the traditional 5-8 steps to less than 3 steps, and the assembly time is reduced by at least half. The wire groove size adaptation achieves multi-specification compatibility, suitable for power wire cores of different wire diameters, without the need to replace special accessories. 2. In this utility model, a clamp-type fixing method is adopted with secondary screw locking. The mechanical limiting of the clamp plate and the connecting body is combined with screw locking to form a double fixation, which avoids the single point of force on the wire core. Compared with the traditional method, the contact resistance is greatly reduced, effectively reducing the risk of overheating. The wire hole formed by the splicing of wire grooves can prevent the wire core from shifting and ensure the stability of the conductive area. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0014] Combination Figures 1 to 5 The power plug inner frame shown includes a pair of metal contacts 1 and a pin insulator 2. The metal contacts 1 are divided into a male contact and a female contact and are respectively inserted into the two ends of the pin insulator 2. The top of the metal contacts 1 extends to form a connector 101. A clamping plate 3 is provided on the outside of the connector 101, and the clamping plate 3 and the connector 101 clamp the power cord core.
[0015] The outer surface of the connector 101 is provided with a wire groove 102, and the clamping plate 3 is also provided with a wire groove 102. The two wire grooves 102 are positioned opposite each other to form a wire hole 4.
[0016] A square hole 103 is provided through the connector 101.
[0017] The clamping plate 3 is bent on one side and has a connecting plate 301. The other end of the connecting plate 301 is provided with a limiting rod 302. The edges of the limiting rod 302 on the side are all rounded. The clamping plate 3, the connecting plate 301, and the limiting rod 302 are an integral structure.
[0018] The width of the connecting plate 301 does not exceed the width of the square hole 103, and the length of the limiting rod 302 is not less than the width of the square hole 103 and less than the height of the square hole 103. After the connecting plate 301 and the limiting rod 302 are vertically inserted into the square hole 103, they are flipped to form a limit.
[0019] The clamp 3 is engaged and locked to the upper end of the connector 101 by screw 5, which is located on the side of the wire hole 4.
[0020] Working principle: During the use of this utility model, when wiring, the connecting plate 301 and the limiting rod 302 are vertically inserted into the square hole 103 of the connector 101. The clamping plate 3 is flipped so that the limiting rod 302 is locked on the outside of the square hole 103 to achieve pre-fixation. Then, the power cord core is placed in the wire groove 102 of the connector 101. The clamping plate 3 is closed so that its wire groove 102 is aligned with the wire groove 102 of the connector 101 to form a wire hole 4 and wrap the power cord core. Finally, the screw 5 is tightened so that the clamping plate 3 and the connector 101 press the wire core together to complete the wiring.
