Description

Technical Field

[0001] The present application relates to the technical field of automobile accessories, and in particular to a pull-resistant connection terminal for automobile wiring harnesses. Background Art

[0002] Terminal blocks are devices used to connect electrical equipment and conductors, and are widely used in electrical engineering, automation equipment, and instrumentation. They effectively connect, disconnect, and distribute circuits, ensuring the proper flow of current and improving the reliability of circuit connections.

[0003] After searching, the announcement number is CN218940054U, which discloses a main body, a plurality of terminal blocks are provided on the top of the main body, a terminal slot is provided on the terminal block, a conductive sheet is provided on the bottom of the terminal slot, a limiting bolt is screwed on the conductive sheet, an annular limiting groove is provided in the middle of the inner wall of the terminal slot, a limiting ring is movably provided in the annular limiting groove, a linkage channel is provided between the terminal blocks, and a pulling-resistant wiring structure is provided on the terminal. When connecting, the wire is inserted into the terminal slot, and the wire passes through the limiting ring. After the conductive wire of the wire contacts the conductive sheet, it is clamped and fixed by tightening the limiting bolt, and then the transmission bolt is screwed in. As the transmission bolt moves horizontally to the left, the transmission bolt drives the rotationally connected limiting ring, and the limiting ring clamps and limits the outer shell of the wire. At the same time, the limiting ring cooperates with other limiting rings through the connecting block to clamp the other connected wires, which has an anti-pulling effect.

[0004] However, the connection terminals of existing automotive wiring harnesses often fix the exposed copper wire portion of the automotive wiring harness by bending the wire clamping part. This may cause the copper wire to become loose due to dragging, resulting in poor contact, or even cause the copper wire to break due to the strong pulling force of the wiring harness, making it impossible to electrically connect to the connector.

[0005] Therefore, it is necessary to provide a pulling-resistant automobile wiring harness terminal to solve the above problems.

[0006] It should be noted that the above information disclosed in this Background section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute prior art. Utility Model Content

[0027] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0028] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present invention.

[0029] See also Figure 1-4 , the embodiment provided by the utility model:

[0030] A pull-resistant terminal for automotive wiring harnesses, comprising a connector 1 and a wire clamping portion 3 for clamping the wiring harness. The connector 1 and the wire clamping portion 3 are integrally formed, and a mounting hole 2 is provided on the side wall of the connector 1. The mounting hole 2 is sleeved on the terminal post and the connector 1 can be fixed to the terminal post of the corresponding device by screws. The wire clamping portion 3 includes a first support plate 31, a bending portion 32 and a tooth groove 33. The top surface of the first support plate 31 is integrally formed with the connector 1, and the bottom surface of the first support plate 31 is integrally formed with the top surface of the fixing plate 41. The side walls of the first support plate 31 are respectively integrally formed with a bending portion 32, and the outer side of the bending portion 32 is provided with a tooth groove 33.

[0031] By placing the exposed copper wire portion of the automobile wiring harness on one side of the first support plate 31 and then squeezing the bent portion with a clamping tool so that the bent portion can bend toward one side of the first support plate 31, and then fixing the exposed copper wire portion of the automobile wiring harness on the first support plate 31 through the tooth groove 33, the automobile wiring harness and the connector 1 can be conductive and can transmit signals or supply power.

[0032] In order to prevent the exposed copper wire part of the automobile wiring harness from being pulled between the wiring harness and the terminal, causing the copper wire to break and resulting in poor contact, a pre-tightening part 4 is integrally formed on the bottom surface of the wire clamping part 3. The pre-tightening part 4 includes a fixed plate 41 and a rotating plate 42. The fixed plate 41 and the rotating plate 42 form a runway-shaped clamping ring. One side of the fixed plate 41 is rotatably connected to one side of the rotating plate 42 through a rotating mechanism, and the other side of the fixed plate 41 is clamped and connected to the other end of the rotating plate 42 through a clamping mechanism. The side walls of the fixed plate 41 and the rotating plate 42 are both penetrated by a clearance groove 48. The bottom surface of the inner part of the clearance groove 48 is provided with a rack 5 integrally formed with the fixed plate 41 and the rotating plate 42, and the two racks 5 are movably connected in the clearance groove 48.

[0033] The rotating plate 42 is opened with the fixed plate 41 through the rotating mechanism, so that the engaging mechanism is released from the engaging state, and the leather wire part of the automobile wiring harness is placed on one side of the fixed plate 41, and then the rotating plate 42 is rotated again through the engaging mechanism to engage with one side of the fixed plate 41, so that under the action of the rack 5, the leather wire part of the automobile wiring harness is clamped to achieve an anti-pull effect.

[0034] Specifically, if the automobile wiring harness is pulled by external force, the leather wire part of the automobile wiring harness generates an outward pulling force from the bottom of the fixed plate 41 and the rotating plate 42, and the top of the rack 5 is not connected and movable in the makeshift groove 48, so that the two racks 5 gather inward, and further clamp the leather wire surface of the automobile wiring harness, thereby effectively preventing the copper wire part of the automobile wiring harness from being debonded or having poor contact on the clamping part 3.

[0035] Among them, the rotating mechanism includes a rotating column 43, a shaft 44 and a rotating drum 45. The rotating column 43 is integrally formed with the two ends of one side wall of the fixed plate 41, and the two ends of the shaft 44 are fixedly connected to the inside of the rotating column 43. The rotating drum 45 is integrally formed with one side wall of the rotating plate 42. A through hole 6 is opened through the inside of the rotating drum 45, and the rotating drum 45 is rotatably connected to the side wall of the shaft 44 through the through hole 6.

[0036] One side of the rotating plate 42 rotates on the side wall of the shaft 44 through the rotating cylinder 45, so that the rotating plate 42 can be rotatably connected to one side of the fixed plate 41 to achieve the opening and closing state between the rotating plate 42 and the fixed plate 41.

[0037] The locking mechanism includes a clamping head 47 and a clamping slot 46. The clamping slot 46 is provided on the side wall of the other side of the fixed plate 41, and the clamping head 47 is integrally formed on the other side of the rotating plate 42. The clamping head 47 is connected to the internal locking of the clamping slot 46. By locking the clamping head 47 in the clamping slot 46, the rotating plate 42 and the other side of the fixed plate 41 can be engaged or released and opened through the rotating mechanism, so that the sheath part of the wiring harness can be clamped and installed.

[0038] As an optimization technical solution of the present application, the two racks 5 are staggered, and the tooth grooves 33 can also be staggered by staggering the outer rack 5, so that the sheath part of the wiring harness can be better clamped.

[0039] As an optimization technical solution of the present application, the teeth 33 on the bending portion 32 are arranged vertically, and the teeth 33 of the rack 5 are arranged horizontally. The horizontal arrangement of the teeth 33 can further increase the friction with the surface of the wire harness to improve the anti-pull ability.

[0040] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
