The connector portion 10 has a connector cavity 11 and a positioning groove 12 formed within it, and the contact spring 31 is located within the connector cavity 11. A positioning protrusion 13 is formed on the outside of the connector portion 10, and the positioning protrusion 13 is located away from the positioning groove 12. The positioning groove 12 and the positioning protrusion 13 cooperate with each other to ensure precise polarization alignment between the connector portion 10 and the device interface, effectively avoiding damage to the contact spring 31 caused by reverse insertion, misalignment, or other reasons.
[0044] In some specific embodiments, please refer to Figure 3The cable holder 20 is provided with limiting baffles 21 on its two short sides and with snap-fit grooves 22 on its two long sides.

[0046] Figure 5 A three-dimensional structural schematic diagram of the metal terminal in an embodiment of this utility model is shown. Figure 6 The diagram shows a front view of the metal terminal in an embodiment of the present invention. Each of the non-stripping wire connectors 32 is composed of a first metal sheet 310, a second metal sheet 320, and a third metal sheet 330 connected in sequence. The first metal sheet 310 and the third metal sheet 330 are parallel to each other, and the first metal sheet 310 and the second metal sheet 320 are perpendicular to each other. Each of the non-stripping wire connectors 32 is provided with a burst-type wire-locking groove 301, which penetrates the first metal sheet 310, the second metal sheet 320, and the third metal sheet 330. The third metal sheet 330 is connected to the contact spring 31. Figure 7 A three-dimensional cross-sectional structural diagram of the connector body in an embodiment of the present invention is shown. A limiting cable slot 23, a first card slot 24 and a second card slot 25 are provided in any of the cable slots. The limiting cable slot 23 passes through the first card slot 24 and the second card slot 25. The second card slot 25 is connected to the connector portion 10. Figure 8 A cross-sectional structural schematic diagram of the connector in an embodiment of the present invention is shown. In one of the wire-locking positions, the first metal piece 310 is embedded in the first card slot 24, the second metal piece 320 spans the first card slot 24 and the second card slot 25, and the third metal piece 330 is located in the second card slot 25; the extrusion-type wire-locking groove 301 is located in the limiting wire-locking groove 23.
[0047] Please see Figure 2 , Figure 3 and Figure 6Inserting wire 1 into a stripper clip 32 essentially means inserting wire 1 into a rupture-type clip groove 301. During the insertion process, the insulation layer of wire 1 is squeezed and cut by the first metal piece 310 and the third metal piece 330, both of which come into contact with the metal core of wire 1. In this way, wire 1 is simultaneously clipped into both the first metal piece 310 and the third metal piece 330, resulting in high connection stability. The inserted wire 1 is not easily loosened or detached from the rupture-type clip groove 301. Moreover, this creates two electrical contact points between wire 1 and the stripper clip 32, which not only helps reduce the contact resistance between wire 1 and the stripper clip 32 but also helps ensure a high contact yield between wire 1 and the stripper clip 32.
[0048] Wherein, the overall outer diameter of conductor 1 is W1, the core diameter of conductor 1 is W2, the width of the extrusion-type wire-clamping groove 301 is W3, and the width of the limiting wire-clamping groove 23 is W4, then the following condition is satisfied: W4 = W1 > W2 > W3, ensuring that conductor 1 can be firmly clamped in the corresponding clamping position. The core diameter of conductor 1 is 0.3 to 0.6 mm larger than the width of the extrusion-type wire-clamping groove 301, ensuring that the metal core can fully contact the first metal piece 310 and the third metal piece 330.
[0049] For further details, please refer to Figure 6 The upper part of the extrusion-type wire clamping groove 301 is formed with a wire inlet 3011. The width of the wire inlet 3011 gradually widens in the direction away from the bottom of the extrusion-type wire clamping groove 301, so as to facilitate the guidance of the wire 1 into the extrusion-type wire clamping groove 301.
[0050] In some specific embodiments, please refer to Figure 5 and Figure 6 Each of the metal terminals 30 branches into three contact springs 31 within the connector portion 10, so that each metal terminal 30 has three electrical contact points at its end, ensuring that each metal terminal 30 can make full contact with the device interface, effectively improving the contact reliability and stability between the connector and the device interface.
[0051] In some specific embodiments, please refer to Figure 8 Each of the contact springs 31 has an arc-shaped structure. The arc-shaped structure can provide contact pressure through elastic deformation, which is beneficial to enhance the contact effect between the contact spring 31 and the device interface.
[0052] The connector of this utility model is used as follows:
[0053] First, remove the cover 40 from the cable holder 20; then, insert the wire 1 into the corresponding non-stripping cable head 32, that is, insert the wire 1 into the corresponding extrusion-type cable slot 301; during the insertion of the wire 1, the insulation layer of the wire 1 will be squeezed and cut by the first metal piece 310 and the third metal piece 330. At this time, the first metal piece 310 and the third metal piece 330 will both come into contact with the metal core of the wire 1, forming an electrical connection; finally, fasten the cover 40 onto the cable holder 20, and the printed circuit board in the cover 40 is electrically connected to the second metal piece 320 of the non-stripping cable head 32.
[0054] When connecting the connector of this utility model, the wire 1 is simply inserted into the non-stripping wire clip 32 inside the wire clip holder 20 and the clip cover 40 is fastened. There is no need to strip the insulation layer of the wire 1, making operation simple and convenient. Furthermore, the clip cover 40 contains a printed circuit board with an LED chip 51, which can detect whether the connection status between the connector and the corresponding device is normal and provide real-time status indication via the LED chip 51. Additionally, the connector portion 10 is provided with a positioning groove 12 and a positioning protrusion 13, which work together to ensure precise polarization alignment between the connector portion 10 and the device interface, effectively preventing damage to the contact spring 31 caused by reverse insertion, misalignment, or other issues. Furthermore, the stripperless connector 32 is composed of a U-shaped structure formed by a first metal piece 310, a second metal piece 320, and a third metal piece 330. A compression-type cable-clamping groove 301 penetrates through these three pieces, providing two insertion points for the conductor 1, enhancing connection stability. It also allows the conductor 1 to form two electrical contact points with the stripper connector 32, reducing contact resistance and ensuring high contact yield. Additionally, each metal terminal 30 branches within the connector portion 10 to form three arc-shaped contact springs 31. This provides each metal terminal 30 with three electrical contact points at its end that can provide contact pressure through elastic deformation, ensuring full contact between each metal terminal 30 and the device interface. This effectively improves the reliability and stability of the connector-device interface contact.
[0055] The connector provided by the embodiments of this utility model has been described in detail above. Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
