Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present utility model, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0027] As a medium for signal or power transmission in modern devices, connectors have become an indispensable component in modern devices, and connectors are generally installed at the end of wires. Traditional connectors generally use the staggered front and rear steps of the upper and lower covers to form a wire biting function, and when users use it, each wire diameter needs to match the wire cover of the corresponding wire diameter, which is cumbersome to use.

[0028] In order to solve the above problems, this embodiment discloses a connector that can adapt to wires of different wire diameters, and its structure is as follows: Figures 1 to 7As shown, the connector includes a connector body 100, a terminal 101 mounted on the connector body 100, a bottom cover 102 and an upper cover 103, wherein the bottom cover 102 and the upper cover 103 are respectively buckled to form a wire hole 105 for clamping the wire 104; the bottom cover 102 is provided with a bolt hole 106 connected to the wire hole 105, and preferably, the bolt hole 106 is arranged perpendicular to the axial direction of the wire hole 105; the upper cover 103 is provided with a wire biting groove 107 connected to the wire hole 105, and a wire clamping bolt 108 is provided in the bolt hole 106, and the lower end of the wire clamping bolt 108 protrudes between the connector body 100 and the bottom cover 102; when the upper cover 103 is pressed, the lower end of the wire clamping bolt 108 contacts the connector body 100, and the upper end of the wire clamping bolt 108 squeezes a section of the wire 104 into the wire biting groove 107.

[0029] Specifically, in the present embodiment, a connector that can adapt to wires of different wire diameters is used. When the wire 104 is placed in the wire hole 105, the upper cover 103 is pressed so that the lower end of the wire clamping bolt 108 contacts the connector body 100, and finally the upper end of the wire clamping bolt 108 squeezes a section of the wire 104 into the wire biting groove 107, thereby fixing the wire 104. Compared with the traditional connector structure, the present invention forms a wire biting structure through the upper cover 103 and the wire clamping bolt 108, and there is no need to match the wire 104 of the corresponding specification, thereby improving the applicability of the connector of the present embodiment.

[0030] In this embodiment, the connector body 100 is a plastic integrated structure, and the terminal 101 is a piercing structure. When the wire 104 is pressed by the upper cover 103 and the wire clamping bolt 108, the outer layer of the wire 104 can be automatically pierced to form an electrical connection with the wire 104; in addition, the wire clamping bolt 108 can be as follows Figure 1-5 The multiple structures shown can also be Figure 6-7 Monomer structure.

[0031] Specifically, one end of the wire clamping bolt 108 close to the wire hole 105 is a trapezoidal structure, which can increase the pressure when the wire clamping bolt 108 contacts the wire 104 and improve the success rate of the wire clamping bolt 108 squeezing the wire 104 into the wire biting groove 107.

[0032] Furthermore, the inner side wall of the connector body 100 is provided with a first card slot 109 and a second card slot 110 spaced apart from each other, and one side of the upper cover 103 is provided with a buckle 111 for engaging with the first card slot 109 or the second card slot 110 . When the upper cover 103 is not pressed in, that is, the wire latch 108 does not squeeze the wire 104 in, at this time, the buckle 111 is engaged with the first clamping groove 109, which can play a temporary storage role; then, the upper cover 103 is pressed hard, and the buckle 111 is disengaged from the first clamping groove 109 and engaged with the second clamping groove 110. At this time, the lower end of the wire latch 108 is in conflict with the connector body 100, and the upper end of the wire latch 108 holds a section of the wire 104. Preferably, the number of the first clamping groove 109, the second clamping groove 110 and the buckle 111 are all two, and the two first clamping grooves 109, the second clamping groove 110 and the buckle 111 are symmetrically arranged with respect to the upper cover 103, respectively, to ensure that the upper cover 103 and the connector body are specific, the thickness of the clamping bolt hole 106 is greater than the thickness of the clamping bolt 108, and the inner side wall of the clamping bolt hole 106 is provided with a connecting strip 112, and the wire latch 108 is connected to the bottom cover 102 through the connecting strip 112. Generally, the wire clamping bolt 108 is integrally formed with the bottom cover 102 via the connecting strip 112 ; when the top cover 103 is pressed, the connecting strip 112 breaks, the wire clamping bolt 108 separates from the bottom cover 102 and squeezes a section of the wire 104 into the wire biting groove 107 .

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
