However, there are some problems with the clamping spring pivoting around a fixed rotating shaft, and the flipping opening and closing have the same flipping path, which is relatively laborious when flipping open; and the locking force is relatively small after flipping closed. Summary of the invention

[0004] In view of this, an object of the present invention is to provide a wire clamp and a photovoltaic connector that can be quickly connected to solve the above problems.

[0010] Furthermore, the clamping spring comprises two clamping legs arranged in parallel; a protrusion is arranged on the contact section of the fixing bracket; when the clamping spring is in a closed state, the protrusion is placed between the two clamping legs.

[0011] Furthermore, it also includes a handle arranged on the operating leg of the clamping spring, and two fixing parts are arranged on the handle; wherein the clamping leg away from the wire insertion side is constructed with a first bending part and a second bending part; the two fixing parts are respectively arranged in the first bending part and the second bending part.

[0012] Furthermore, a first locking portion is provided on the fixing bracket, and a second locking portion which can be locked with the first locking portion is provided on the clamping spring, so that the clamping spring can be locked on the fixing bracket when it is flipped and in a closed state.

[0017] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0018] The present invention provides a wire clamp capable of rapid wiring, comprising a fixed bracket and a clamping spring movably connected to the fixed bracket, wherein the clamping spring does not have a fixed pivot axis during the flipping process and can perform sliding flipping; when the clamping spring flips outward to open, a second flipping trajectory approaches and abuts against a second supporting portion; and during the flipping process, the second supporting portion performs sliding flipping, so that the flipping force of an operating leg acting on the clamping spring gradually becomes lighter as the angle between the operating leg and a contact section of the fixed bracket increases, thereby achieving easy flipping and labor-saving flipping to open the clamping spring; and when the clamping spring flips inward to close, the first supporting portion approaches and abuts against the first flipping trajectory, and performs sliding flipping along the first supporting portion during the flipping process, so that the locking force of the clamping leg when closed can rapidly increase as the angle between the operating leg and the contact section decreases, thereby increasing the locking force on the conductor end and improving the firmness of locking the conductor end.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0041] Example

[0042] Combination Figures 1 to 12 As shown, this embodiment provides a wire clamp capable of quick wiring, comprising a fixed bracket 1 and a clamping spring 2 movably connected to the fixed bracket; the fixed bracket 1 is provided with a first supporting portion 12 and a second supporting portion 13; the clamping spring 2 is provided with a rotating portion 9 disposed between the first supporting portion 12 and the second supporting portion 13; the rotating portion 9 is provided with a first flip track 7 cooperating with the first supporting portion 12 and a second flip track 8 cooperating with the second supporting portion 13;

[0043] When the clamping spring 2 flips downward, the clamping spring 2 slides and flips under the action of the first flipping trajectory 7 and the first supporting portion 12 to reach a closed state; when the clamping spring 2 flips upward, the clamping spring 2 slides and flips under the action of the second flipping trajectory 8 and the second supporting portion 13 to reach an open state.

[0044] In this embodiment, the clamping spring 2 and the fixing bracket 1 are integrally formed by punching and bending a metal plate. Figures 6 to 8 As shown, the two sides of the operating leg 5 are stamped and bent downward to form the rotating portion 9, the movable groove 6 is arranged on the side of the rotating portion 9 close to the insertion side E, and a notch 10 is arranged at the upper end of the movable groove 6 away from the insertion side E, so that the rotating portion 9 is similar to a hook shape. In this embodiment, the inner wall surface and the outer wall surface of the movable groove 6 close to the insertion side E form the first flip track 7 and the second flip track 8. Figure 4 and Figure 5 As shown, the fixing bracket 1 is connected to the two side walls of the contact section 3 and is bent outward to form a hollow support ear 11, which can be assembled with the movable groove 6 through the notch 10. The upper part of the support ear 11 is configured as the first support part 12 that can cooperate with the first flip track 7; the lower part of the support ear 11 is configured as the second support part 13 that can cooperate with the second flip track 8.

[0045] like Figures 1 to 3 As shown, by setting the first flipping track 7 and the second flipping track 8 and the first support portion 12 and the second support portion 13, the clamping spring 2 does not have a fixed pivot axis during the flipping process. Specifically, when the clamping spring 2 flips outward to open, the second flipping track 8 approaches and abuts against the second support portion 13, and the first support portion 12 is away from the first flipping track 7 in the movable groove 6. At this time, during the flipping process, the second flipping track 8 slides along the second support portion 13, that is, the second flipping track 8 slides on the second branch 13, and the flipping action of the clamping spring 2 is realized synchronously, so that the flipping force of the operating leg 5 acting on the clamping spring 2 gradually becomes lighter as the angle between the operating leg 5 and the contact section 3 of the fixed bracket 1 increases, that is, when the operating leg is initially flipped up in the closed state, it can be easily flipped later, and the clamping spring 2 can be flipped open with effortless operation. When the clamping spring 2 flips inward and closes, the first supporting portion 12 approaches and abuts against the first flipping trajectory 7 in the movable groove 6; the second flipping trajectory 8 moves away from the second supporting portion 13. At this time, during the flipping process, the first flipping trajectory 7 slides along the first supporting portion 12, that is, the first flipping trajectory 7 slides on the first branch 12, and the flipping action of the clamping spring 2 is realized synchronously, so that the locking force of the clamping leg 4 when closing can increase rapidly as the angle between the operating leg 5 and the contact section 3 decreases, thereby increasing the locking force on the conductor end and improving the firmness of the locking of the conductor end.

[0046] In this embodiment, if Figures 8 to 12 As shown, the clamping spring 2 includes two clamping legs 4 arranged in parallel, and a handle 14 attached to the operating leg 5. The clamping leg 4 away from the insertion side E is bent to form a first bending portion 15 away from the insertion side E, and a second bending portion 16 close to the insertion side E; the bending directions of the first bending portion 15 and the second bending portion 16 are opposite. Two fixing portions 17 are arranged on the handle 14; the two fixing portions 17 are respectively arranged in the first bending portion 15 and the second bending portion 16. Specifically, the two fixing portions 17 are extended from a lower side wall of the handle 14 along the width direction, and can be inserted into the first bending portion 15 and the second bending portion 16 from one side; and a limiting protrusion 18 is arranged on the side wall away from the handle 14 and on one of the fixing portions 17, which is used to limit the clamping leg 4 in the width direction to prevent the clamping spring 2 from being separated from the handle 14.

[0047] Of course, in this embodiment, a first locking portion 19 is provided on the fixing bracket 1, and a second locking portion 20 which can be locked with the first locking portion 19 is provided on the clamping spring 2, so that the clamping spring 2 can be locked on the fixing bracket 1 when it is flipped and in a closed state.

[0048] Preferably, if Fig.19 As shown, a protrusion 21 is provided on the contact section 3; when the clamping spring 2 is flipped and in a closed state, the protrusion 21 is placed between the two clamping legs 4; so that after the wire 41 is inserted into the wire clamp and the two clamping legs 4 are pressed down, a bulge deformation occurs between the two clamping legs 4, so that the wire 41 placed between the two clamping legs is in a wavy curve shape, so that the wire 41 has a greater combined holding force and can withstand a greater axial pull-out force, thereby increasing the anti-loosening friction force of the wire 41.

[0049] The present invention further provides a photovoltaic connector, comprising a male end 39 and a female end 40 that can be quickly docked to achieve electrical connection, and the male end 39 and the female end 40 are provided with the wire clamp 100 .

[0050] Specifically, Figures 13 to 18As shown, both the male end 39 and the female end 40 include an outer shell 22, a docking body connected to the outer shell 22, and an inner core body 23 placed in the outer shell for installing the wire clamp 100; wherein, the male end 39 pin 24 is provided on the fixing bracket 1 of the male end 39; and the female end 40 jack 25 adapted for electrical connection with the male end 39 pin 24 is provided on the fixing bracket 1 of the female end 40. After the male end 39 and the female end 40 are docked, the male end 39 pin 24 is inserted into the female end 40 jack 25 to realize the electrical connection of the two wires connected to the wire clamp 100 of the male end 39 and the female end 40.

[0051] In this embodiment, the two docking bodies can realize active clamping; wherein the female end 40 docking body 27 is provided with an elastic clamping arm 28 with a clamping portion 29 at the front end; the male end 39 docking body 26 is provided with a clamping groove 30, and the elastic clamping arm 28 can pass through the clamping groove 30, so that the clamping portion 29 is clamped on the clamping end surface of the clamping groove 30. The female end 40 docking body 27 is provided with a first limiting surface 31, and the end surface of the clamping groove 30 is a second limiting surface 32 adapted to the first limiting surface 31. When the first limiting surface and the second limiting surface 32 are in contact, the clamping portion 29 is just clamped with the clamping end surface. An elastic support arm 33 is provided on the male end 39 docking body 26, and its front end portion is placed on the clamping portion 29. When pressure is applied to the elastic arm, it can act on the clamping portion 29 to cause the elastic clamping arm 28 to undergo elastic deformation, so that the clamping portion 29 is moved away from the clamping end face, thereby releasing the clamping and realizing the separation of the two docking bodies.

[0052] In this embodiment, in order to prevent the wires at both ends from being easily pulled out after the male end 39 and the female end 40 are connected, a wire locking tooth 34 is provided between the outer shell 22 and the connecting body. During the process of the outer shell 22 being screwed with the connecting body through threads, the teeth of the wire locking tooth 34 are contracted toward the axis to lock the wires and prevent the wires from being pulled out. At the same time, in order to achieve the sealing of the internal wire clamp 100 and avoid the risk of short circuit caused by water ingress; an O-ring 35 is provided on the connecting body to achieve the sealing of the outer shell 22 and the connecting body; a sealing ring 36 is provided inside the wire locking tooth 34 and is sleeved on the wire. Under the action of the outer shell 22 pressing against the wire clamp 100 and the pressing of the teeth of the wire locking tooth 34 contracting toward the axis, the outer shell 22 and the wire are sealed.

[0053] Preferably, it also includes a plug-in safety lock 37 that is covered outside the two docking bodies, which is used to cover the elastic support arm 33 to prevent the elastic support arm 33 from being accidentally pressed, causing the male end 39 and the female end 40 to be released from the clamping state, thereby falling off from each other. The plug-in safety lock 37 is provided with unlocking holes 38 on both sides along the docking direction of the docking body, and the unlocking holes 38 are for a screwdriver to be inserted to press the elastic support arm 33, thereby releasing the clamping state of the male end 39 and the female end 40, and facilitating the separation of the male end 39 and the female end 40.
