[0023] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the accompanying drawings. However, the present invention may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present disclosure.
[0024] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.
[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0026] like Figure 1-5 As shown, the end connector provided by an embodiment of the invention is shown. It can also be called a self-locking end connector, a self-locking connector, a drainage wire clamp, a torque locking device, or a torque universal wire clamp. It includes a main body 1. A first slide groove 11 and a second slide groove 12 are provided on the main body 1, which are interconnected; a slider 13 is slidably fitted in the first slide groove 11, and a wire pressing block 14 is slidably fitted in the second slide groove 12. An adjusting bolt 15 is also threadedly fitted on the main body 1, and the adjusting bolt 15 is suitable for driving the wire pressing block 14 to slide along the second slide groove 12; the wire pressing block 14 and the slider 13 are suitable for clamping the cable 2, and the slider 13 is suitable for connecting the terminal 3 of the transformer; specifically, the connection between the slider 13 and the transformer can be a common connection method such as a threaded connection and a snap connection.
[0027] When in use, place the cable 2 in the second slide groove 12, and drive the wire pressing block 14 by adjusting the bolt 15, so that the wire pressing block 14 slides in the second slide groove 12 in the direction close to the slider 13. At this time, the wire pressing block 14 will push the cable 2 and the slider 13 to move in turn until the slider 13 abuts against the end of the first slide groove 11. The slider 13 will stop moving, and the wire pressing block 14 can continue to move close to the slider 13 to clamp the cable 2.
[0028] As can be seen from the above usage process, the terminal connector of the present invention can be connected to the cable 2 and the transformer by simply adjusting the bolt 15, which is very convenient. In addition, when the cable 2 is clamped and fixed, the slider 13 will abut the end of the first slide groove 11, thereby ensuring the stability of the connection between the slider 13 and the transformer.
[0029] As a preferred embodiment, a accommodating chamber 16 is further provided on the main body 1. The accommodating chamber 16 is located on one side of the second slide groove 12, and a check block 17 is provided in the accommodating chamber 16. An elastic member 172 is provided between the check block 17 and the cavity wall of the accommodating chamber 16, and the elastic member 172 is suitable for making the check block 17 abut against the wire pressing block 14 to prevent the wire pressing block 14 from moving away from the slider 13, wherein the elastic member 172 can be a spring. Through the above-mentioned setting method, the check block 17 can play a role in self-locking the wire pressing block 14, that is, it can avoid the loosening of the wire pressing block 14 caused by the loosening of the adjusting bolt 15, thereby ensuring the reliability of the connection of the end connector of the present invention. Specifically, the check is achieved by providing bevel teeth on the two opposite surfaces between the check block 17 and the wire pressing block 14. Its principle is similar to that of a ratchet mechanism, and the check principle will not be further described here.
[0030] Preferably, the check block 17 is provided with a hinge post 171, and the main body 1 is provided with a hinge hole for accommodating the hinge post 171, and the hinge post 171 is installed in the hinge hole. That is, the check block 17 is connected to the main body 1 via the hinge post 171, so that the check block 17 can only rotate about the hinge post 171 and cannot slide along the trajectory of the second slide groove 12, further ensuring the check block 17's anti-return effect.
[0031] Preferably, a first housing 4 is provided over the main body 1. The first housing 4 is adapted to enclose the second chute 12 and the accommodating cavity 16 and is adapted to be secured to the main body 1 via a first bolt 41. The provision of the first housing 4 encloses both the wire pressing block 14 and the check block 17, providing support and surrounding support, thereby preventing the wire pressing block 14 and the check block 17 from being dislodged and improving the reliability of the terminal connector of the present invention. The first bolt 41 allows the first housing 4 to be loosened from the main body 1 when the wire pressing block 14 or the check block 17 needs to be replaced.
[0032] Preferably, the sliding mating surface between the slider 13 and the first chute 11 is a conical surface with a Morse taper, so that the slider 13 is self-locked in the first chute 11. That is, in the present invention, the slider 13 and the first chute 11 can be self-locked, thereby further improving the reliability of the end connector of the present invention.
[0033] Preferably, the main body 1 is further provided with a mounting groove 18, which is aligned with the first slide groove 11, and the first slide groove 11 is positioned between the mounting groove 18 and the second slide groove 12. An abutment block 19 is mounted within the mounting groove 18, adapted to abut against the slider 13. Semicircular holes 51 are provided on the two opposing surfaces of the abutment block 19 and the slider 13. When the abutment block 19 abuts against the slider 13, the two semicircular holes 51 form a circular hole, wherein threads are provided within the circular hole. Specifically, in the present invention, the slider 13 and the transformer terminal 3 are preferably connected by a thread, and the threaded hole is formed by combining the two semicircular holes 51. This arrangement facilitates the installation of the terminal connector of the present invention and the transformer terminal 3.
[0034] Preferably, a positioning protrusion 181 is provided in the mounting groove 18, and a groove is formed on the abutment block 19 to cooperate with the positioning protrusion 181. Since the hole for mounting the transformer terminal 3 is a threaded hole, the positioning protrusion 181 is used to position the abutment block 19 in the installation direction. In this way, when the abutment block 19 is installed upside down, the positioning protrusion 181 will not cooperate with the groove, thereby preventing it from being installed upside down.
[0035] Preferably, a second housing 6 is provided over the main body 1. This second housing 6 is adapted to retain the abutment block 19 within the mounting groove 18 and the slider 13 within the first mounting groove 18. The second housing 6 is secured to the main body 1 via a second bolt 61. Similarly, the second housing 6 encloses the slider 13 and abutment block 19, providing support and enclosure. This prevents the slider 13 and abutment block 19 from dislodging from the main body 1, thereby enhancing the reliability of the terminal connector of the present invention.
[0036] Preferably, notches 71 are provided on both opposing surfaces of the wire pressing block 14 and the slider 13, each of which is provided with anti-slip protrusions 711. The provision of notches 71 better adapts to the shape of the cable 2, thereby enabling the cable 2 to be clamped more securely. The provision of anti-slip protrusions 711 also increases the friction between the cable 2, the wire pressing block 14, and the slider 13, further enhancing the stability of the cable 2 connection.
[0037] The above are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
