Therefore, the features defined as "first", "second", "third", etc. can explicitly or implicitly include one or more of the features. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0032] like Figure 3-Figure 9 As shown, the horn connector of the present invention includes a main colloid 1, two hooks 2 respectively hinged at both ends of the main colloid 1, and two self-locking blocks 3 respectively hinged at both ends of the main colloid for limiting the rotation of the hooks 2. A limiting groove 21 is provided on the side of the hook 2 facing the self-locking block 3, and a buckle portion 32 is provided on the side of the self-locking block 3 facing the hook 2.

[0033] The buckle portion 32 is locked in the limiting groove 21 to limit the rotation of the hook 2, so that the hook 2 remains in a closed state. After the buckle portion 32 exits the limiting groove 21, the hook 2 can be rotated into an unlocked state.

[0034] In this embodiment, the two hooks 2 include a first hook and a second hook, and the first hook and the second hook are symmetrically hinged at both ends of the main colloid 1. The two self-locking blocks 3 include a first self-locking block and a second self-locking block, and the two self-locking blocks 3 are arranged on the outside of the two hooks 2 in opposite directions. Figure 3 and Figure 4 As shown, the first self-locking block is arranged on the left side of the first hook, and the second self-locking block is arranged on the right side of the second hook.

[0035] Combination Figure 5 As shown, in this embodiment, the main colloid 1 is a long strip structure, which includes a slot body 11 , in which a male slot plate 4 and contact terminals 5 penetrating the male slot plate 4 are arranged.

[0036] Combination Figure 6 and Figure 8 As shown, further, the two ends of the main colloid 1 in the length direction are respectively provided with hook grooves 12, the hook grooves 12 are arranged at the two ends of the groove body 11, and the two sides of the hook groove 12 are oppositely provided with first positioning holes 121, and the two sides of the hook groove 12 here are the two sides of the rotation direction of the hook 2.

[0037] Positioning posts 22 are provided on opposite sides of the hook 2 , which are the two sides in the rotation direction of the hook 2 , or the two sides in the width direction of the hook 2 . The positioning posts 22 can be rotatably installed in the first positioning hole 121 .

[0038] A limiting protrusion 23 is further provided on the opposite side of the hook 2 . The limiting protrusion 23 abuts against the inner wall surface of the hook groove 12 . The limiting protrusion 23 and the positioning column 22 are located on the same side. The limiting protrusion 23 can limit the rotation of the hook 2 .

[0039] Combination Figure 6 and Fig. 9 As shown, mounting grooves 13 are respectively provided at both ends of the main colloid 1, and the mounting grooves 13 are connected to the hook grooves 12, so that the hook 2 and the self-locking block 3 have a certain activity space, and the hook 2 can rotate into the mounting groove 13. Furthermore, second positioning 131 are relatively provided on both sides of the mounting groove 13.

[0040] The self-locking block 3 includes a columnar main body 31. In the present embodiment, the main body 31 is a substantially rectangular parallelepiped structure. The buckle portion 32 is disposed at a first end of the main body 31. A positioning shaft 311 is disposed at a second end of the main body 31. The positioning shaft 311 can be rotatably mounted in the second positioning hole 311. Of course, a cylindrical structure can also be disposed on the opposite side of the main body 31 in the width direction. The cylindrical structure can be rotatably mounted in the second positioning hole 311.

[0041] Preferably, the cross-sectional area of ​​the buckle portion 32 is greater than the cross-sectional area of ​​the main body 31. Of course, the cross-sectional area of ​​the buckle portion 32 may also be equal to the cross-sectional area of ​​the main body 31. It can be understood that the transverse dimension of the buckle portion 32 is greater than the transverse dimension of the main body 31.

[0042] Preferably, the upper side surface of the inner wall of the limiting groove 21 of the hook 2 is provided with a first inclined surface 211, and the upper side surface of the buckle portion 32 is provided with a second inclined surface 321 that matches the first inclined surface 211. When the hook 2 is in a closed state, a self-locking force is formed by the first inclined surface 211 and the second inclined surface 321 to prevent the hook from being opened when accidentally subjected to force. Of course, it is possible to set a plane structure without a inclined surface. It is understandable that the structure of the limiting groove 21 and the buckle portion 32 can be appropriately adjusted according to needs, and no specific requirements are made here.

[0043] Furthermore, the opposite sides of the main body 31 (the two sides facing the inner wall of the installation groove 13) are further provided with limiting protrusions 312, which abut against the inner wall of the installation groove 13, and the limiting protrusions 312 can further limit the rotation of the self-locking block 3.

[0044] Combination Figure 6 As shown, further, an opening is provided on a side of the installation groove 13 away from the hook groove 12, and the opening forms a movable space for the self-locking block 3 to rotate.

[0045] Furthermore, a limit block 132 is provided at the bottom of the opening, and an inclined surface 1321 is provided on the side of the limit block 132 facing the self-locking block 3. When the side of the self-locking block 3 away from the hook 2 abuts against the inclined surface 1321, the self-locking block 3 is restricted and can no longer rotate.

[0046] Furthermore, the limiting block 132 is provided with a notch 1322, and the notch 1322 is a U-shaped structure, a C-shaped structure or a V-shaped structure. Of course, it can also be other structural forms, which are not specifically limited here. The notch 1322 can be provided so that when the self-locking block 3 and the hook 2 are bent outward, the main colloid 1 has an elastic space to prevent the main colloid 1 from being torn.

[0047] In this embodiment, when the hook 2 is locked with the groove of the female connector, the buckle portion 32 of the self-locking block 3 is locked in the limit groove 21, limiting the rotation of the hook 2 and ensuring that the hook 2 is in a closed state. When the hook 2 is to be disconnected from the female connector, the self-locking block 3 is first opened so that the buckle portion 32 exits the limit groove 21, and the hook 2 can be opened and rotated.

[0048] The self-locking block 3 of the horn connector can prevent the top of the hook 2 from being accidentally stressed and opened, thereby ensuring the stability of the closed state of the hook 2. The self-locking block 3 has a simple structure, low manufacturing cost and good applicability.

[0049] It can be understood that the above embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the present invention. It should be pointed out that, for ordinary technicians in this field, the above technical features can be freely combined without departing from the concept of the present invention, and several deformations and improvements can be made, which all belong to the protection scope of the present invention. Therefore, all equivalent changes and modifications made to the scope of the claims of the present invention should belong to the coverage of the claims of the present invention.
