[0002] A European-style socket is a type of socket used in the European standard market with European plugs. Its characteristic is that the grounding spring extends into the round socket. For example, the utility model patent "A European-style Socket" (publication number: 222395093U) discloses a European-style socket. Like traditional European-style sockets, the grounding spring and the metal contacts such as the phase wire socket are fastened to the wiring with bolts. That is, the wiring is pressed against the metal contacts by bolts. This wiring method requires turning the bolts, which is relatively troublesome to operate and cannot achieve quick wiring. Moreover, it is difficult for non-professionals to operate.

[0003] To address the aforementioned problems, this utility model provides improvements. Utility Model Content

[0004] This utility model proposes a European-style quick-connect socket, which solves the above-mentioned problems existing in the use of the prior art.

[0005] The technical solution of this utility model is implemented as follows:

[0006] A European-style quick-connect socket includes a base, a support plate, a panel, and metal contacts. The metal contacts are disposed within the base, which has several wiring holes. The metal contacts have an inverted U-shaped wiring portion on one side of the wiring holes. A wiring spring is disposed within the base, located on one side of the wiring holes within the wiring portion. The wiring spring has a wire clamping portion that bends away from the wiring holes.

Detailed Implementation

[0022] The following will refer to the appendix in the embodiments of this utility model. Figure 1-6 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] As shown in the figure, a European-style quick-connect socket includes a base 1, a support plate 2, a panel 3, and a metal contact 4. The support plate 2 and the panel 3 are fixedly connected to the base 1. The metal contact 4 is disposed inside the base 1. The base 1 has several wiring holes 11. The metal contact 4 has an inverted U-shaped wiring portion 41 located on one side of the wiring hole 11. The base 1 has a wiring spring 5 located inside the wiring portion 41 on one side of the wiring hole 11. The wiring spring 5 has a wire clamping portion 51 bent away from the wiring hole 11. The horizontal part of the wiring portion 41 has an operating port 42 located above the wire clamping portion 51. The base 1 has a cover plate 6 located above the metal contact 4. The cover plate 6 has a swing plate 61 located above the wiring portion 41. The swing plate 61 has a driving portion 62 that passes through the operating port 42 and abuts against the wire clamping portion 51.

[0024] Specifically, the structure of the metal contact 4 being disposed within the base 1 and the cover plate 6 being disposed on the base 1 is as follows: a mounting cavity 12 is formed within the base 1, the metal contact 4 is placed within the mounting cavity 12, a snap-fit ​​plate 63 is formed on the side end of the cover plate 6, a snap-fit ​​hole 64 is provided on the snap-fit ​​plate 63, and a snap-fit ​​protrusion 13 matching the snap-fit ​​hole 64 is formed on the side wall of the base 1. The cover plate 6 is placed on the base 1 to press the metal contact 4 so that the snap-fit ​​protrusion 13 is snapped into the snap-fit ​​hole 64. The fixed connection between the cover plate 6 and the base 1 is achieved through the cooperation of the snap-fit ​​protrusion 13 and the snap-fit ​​hole 64. Furthermore, the cover plate 6 presses the metal contact 4 into the mounting cavity 12 to achieve a stable placement of the metal contact 4 within the base 1, which facilitates the assembly of the socket.

[0025] In the above structure, when it is necessary to connect the wire to the metal contact 4, press the swing plate 61 to make it swing towards the wiring part 41. The swing plate 61 drives the drive part 62 to swing towards the wire clamping part 51 in the operation port 42. The drive part 62 pushes the wire clamping part 51 to swing away from the horizontal part of the wiring part 41. A gap is formed between the end of the wire clamping part 51 and the inner wall of the horizontal part of the wiring part 41, allowing the wire to pass through. The wire is passed through the wiring hole 11 and inserted between the wire clamping part 51 and the horizontal part of the wiring part 41. After releasing the swing plate 61, the wire clamping part 51 swings towards the horizontal part of the wiring part 41 under the action of elastic restoring force, clamping the wire between the wire clamping part 51 and the horizontal part of the wiring part 41 and making close contact with the wiring part 41, thus realizing the connection between the wire and the metal contact. The above wiring method makes the wiring of the socket more convenient and quick, and facilitates the use of the socket.

[0026] Furthermore, based on the above structure, a limiting protrusion 52 is formed on the side end of the wiring spring 5, and a limiting groove 43 matching the limiting protrusion 52 is provided on the vertical part of the wiring portion 41. The limiting protrusion 52 is held in the limiting groove 43. The relative displacement between the wiring spring 5 and the wiring portion 41 is limited by the cooperation between the limiting protrusion 52 and the limiting groove 43, so that the wiring spring 5 is more stably held in the wiring portion 41, thereby ensuring that the clamping part 51 can stably clamp the wiring on the inner wall of the wiring portion 41 and enhance the stability after wiring.

[0027] Furthermore, based on the above structure, a positioning protrusion 14 is formed in the mounting cavity 12, and a positioning hole 53 matching the positioning protrusion 14 is formed on the wiring spring 5. The positioning protrusion 14 passes through the positioning hole 53, and the relative displacement between the wiring spring 5 and the base 1 is limited by the cooperation between the positioning protrusion 14 and the positioning hole 53. Since the wiring spring 5 and the metal contact 4 are limited by the cooperation between the limiting protrusion 52 and the limiting groove 43, the relative displacement between the metal contact 4 and the base 1 is limited, thereby ensuring that the metal contact 4 can be stably held in the mounting cavity 12, and ensuring the stability of the metal contact 4 during and after wiring.

[0028] Furthermore, based on the above structure, an arc-shaped wire clamping notch 54 is formed at the end of the wiring part 41, and an arc-shaped wire clamping groove 44 opposite to the wire clamping notch 54 is formed on the inner wall of the horizontal part of the wiring part 41. When the wire clamping part 51 clamps the wire onto the inner wall of the wiring part 41, the wire is located in the wire clamping groove 44 and the wire clamping notch 54. The wire clamping groove 44 and the wire clamping notch 54 increase the contact area between the wiring part 41 and the wire clamping part 51 and the wire, respectively. This strengthens the stability of the connection between the wire and the metal contact 4, and also strengthens the conductivity between the wire and the metal contact 4.

[0029] Furthermore, based on the above structure, the end of the wire spring 5 away from the wire hole 11 is bent to form a wire support portion 55 located below the horizontal portion of the wire connection portion 41. A wire support portion 55 and the horizontal portion of the wire connection portion 41 are formed to allow the wire to pass through. After the wire passes between the wire clamp portion 51 and the horizontal portion of the wire connection portion 41, it passes into the wire support portion 55 and the horizontal portion of the wire connection portion 41, so that the wire support portion 55 supports the end of the wire and keeps it in contact with the wire connection portion 41, thereby increasing the contact area between the wire and the wire connection portion 41 and the metal contact piece 4, and strengthening the conductivity between the wire clamp and the metal contact piece 4.

[0030] Furthermore, based on the above structure, a first limiting part 45 is formed on the port of the wiring part 41 away from the wiring hole 11, an abutting part 56 is formed on the end of the wiring spring 5 away from the wiring hole 11, and a second limiting part 46 is formed on the port of the wiring part 41 near the wiring hole 11, abutting the clamping part 51. The abutting of the first limiting part 45 and the abutting part 56 and the abutting of the second limiting part 46 and the clamping part 51 enhance the stability of the wiring spring 5 in the wiring part 41, ensuring the stability of the clamping part 51 when driven by the driving part 62, and stably cooperating with the wiring part 41 to clamp the wiring, ensuring the stability after wiring, and increasing the contact area between the wiring spring 5 and the wiring part 41, thereby enhancing the conductivity between the clamping spring and the wiring part 41.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
