Description

Technical Field

[0001] The utility model relates to a wire clamp, in particular to a quick-clamping wire connection structure. Background Art

[0002] A wire clamp is a common product with various forms and types. It mostly realizes fixation and electrical transmission by the clamping action of conductive fittings. For the multi-strand wire clamp product with circumferential clamping, a wrench-type fastener is used. To simplify the structural design, a non-spring elastic structure is adopted to achieve elastic contact and power-on during the rotation of the wrench. In use, due to the large force received during the insertion of the wire clamp, it is easy to retreat, resulting in insufficient tightness of the fitting combination, and the clamping feet are easy to break. And there are instabilities during use, such as abnormal phenomena like the wrench slipping and jamming. Content of the Utility Model

[0003] Aiming at the deficiencies of the existing technology, the utility model provides a quick-clamping wire connection structure.

[0004] To achieve the above object, the technical solution adopted by the utility model is: a quick-clamping wire connection structure, including a cylindrical shell body, an internally arranged contact elastic sheet, an end cover fixedly assembled at the axial end of the shell body, and an abutting member rotatably assembled on the shell body. The shell body is provided with a fixed socket and a movable socket on the axial end face. The end cover has a fixed column inserted and matched with the fixed socket, and the end cover also has a movable column in limit fit with the movable socket. The movable socket forms an open movable slot on the side of the shell body. The contact elastic sheet has a circumferential structure. The contact elastic sheet has concave portions at symmetric two ends. The abutting member has a convex portion with a shape and size suitable for the concave portion. The abutting member is provided with a top hook at one end opposite to the convex portion for abutting and pressing the contact elastic sheet to deform. The abutting member is provided with a cut groove in the center of the convex portion. The abutting member is further provided with a limiting portion on the inner side wall of the cut groove. A slot for inserting the movable column is formed between the limiting portion and the cut groove. The movable column and the limiting portion are in blocking limit.

[0005] The end cover is provided with a convex portion in clamping fit on the side of the fixed column. The fixed column has a hollow structure with a central square shape, and the convex portion has a strip shape.

[0006] The fixed socket and the movable socket are uniformly arranged at intervals along the circumference.

[0007] The movable column is provided with a limiting block with a shape and size suitable for the cut groove. The width of the movable slot is equal to the width of the abutting member.

[0008] The shell body is provided with a reinforcing rib ring at the axial center, and the shell body is provided with external threads on both sides of the reinforcing rib ring.

[0009] ​Beneficial effects of the present invention: The quick-clamp connection structure provided by the present invention is simple in design and easy to produce, reduces the gap between parts and components, enhances the tightness of the connection, and has a reliable flow field during use, avoiding the occurrence of jamming and the like.

[0014] like Figures 1-4 As shown, a quick-clamp connection structure includes a cylindrical housing 1, a built-in contact spring 2, an end cap 3 fixedly mounted on the axial end of the housing 1, and an abutment 4 rotatably mounted on the housing 1. The abutment 4 is mounted on the housing 1 and is constrained by the end cap 3 and other parts to only rotate relative to the housing 1. During this rotation, the contact spring 2 is squeezed and deformed.

[0015] The housing body 1 is provided with a fixed socket 5 and a movable socket 6 on its axial end face. The end cap 3 is provided with a fixed post 7 that engages with the fixed socket 5. The end cap 3 also includes a movable post 8 that limits the position of the movable socket 6. After the end cap 3 is removed, internal components can be installed. Typically, the contact spring 2 is inserted through this post. Before the end cap 3 is plugged in and sealed, the abutment 4 is sleeved against it. Both the fixed post 7 and the movable post 8 serve a certain fixing function, but the movable post 8 also serves to limit the position of the abutment 4.

[0016] The movable socket 6 forms an open movable notch on the side of the shell body 1. The contact spring 2 has a circumferential structure and has recessed portions 9 at both symmetrical ends. The abutment member 4 has a convex portion 10 that matches the shape and size of the recessed portion 9. The abutment member 4 has a top hook 11 on the end opposite the convex portion 10 to abut and compress the contact spring 2 for deformation. The movable notch opens one side of the movable socket 6. The contact spring 2 and the abutment member 4 are mainly connected by the convex portion 10 and the concave portion 9. That is, the concave-convex fit shortens the relative distance, which facilitates the top hook 11 to fully compress the contact spring 2 during rotation, thereby effectively clamping the contact spring 2 and conducting electricity.

[0017] The abutment member 4 has a central slot in the protruding portion 10, and a stopper 12 is provided on the inner sidewall of the slot. The stopper 12 and the slot form a slot for the movable post 8 to be inserted into. The movable post 8 and the stopper 12 engage and limit each other. The abutment member 4 forms a slot with relatively limited sealing. Under normal conditions, the stopper 12 engages the movable post 8 above it. When locked and connected, the abutment member 4 rotates, and the stopper 12 gradually moves away from the movable post 8, without affecting its rotation.

[0018] The end cap 3 is provided with a snap-fitting protrusion 13 on the side of the fixing post 7. The fixing post 7 is a U-shaped structure with a central hollow, and the protrusion 13 is a strip-shaped structure. The protrusion 13 fills the gap during insertion, creating an interference fit and helping to prevent the end cap 3 from falling off. The shape of the fixing post 7 and the protrusion 13 simplifies the structure, facilitates production, and ensures effective use.

[0019] The fixed sockets 5 and movable sockets 6 are evenly spaced along the circumference, meeting the need for multiple wires to use the same terminal clamp. The movable column 8 is equipped with a stopper 14 that matches the size and shape of the slot. The width of the movable slot is equal to that of the abutment 4, further reducing unnecessary gaps and preventing production and use. The shell body 1 is equipped with a reinforcing rib 15 in the axial center, and the shell body 1 has external threads on both sides of the reinforcing rib 15. The reinforcing rib 15 enhances structural strength, and the external threads facilitate closed connection with other accessories.
