Description

Technical Field

[0001] The invention relates to the technical field of wiring terminals, and in particular to a cold-pressed wiring terminal for a connector. Background Art

[0002] Cold-pressed terminals are commonly used connection tools between connectors and cables, belonging to electrical engineering and automation technology. The sleeve part of the terminal is connected to the cable head of the cable. After the cable is connected, the terminal is aligned and placed in the slot at the corresponding position on the connector. After the gasket is placed at the horizontal joint of the terminal, the operating screw is used to fix the gasket and the terminal together in the connector from the top. The sleeve part of the terminal extends to the outside of the connector. The sleeve part of the terminal is short and remains in a straight state, which makes the part of the cable near the terminal easy to move due to external force, which may cause the wiring of the sleeve part of the terminal to be deflected. At the same time, the horizontal joint part of the terminal is directly placed flat on the corresponding gasket in the connector, and the tail of the horizontal joint connecting the terminal and the connector also extends partly to the outside of the crimping boundary, so that the terminal is easily pulled by the rear-end wiring during the connection and separation process. It is easy to move autonomously in the connector. The collision of the terminal at the crimping boundary in the connector may cause the terminal to bend and deform at the crimping boundary, affecting the safe use of the terminal. Summary of the invention

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a cold-pressed terminal for a connector, which extends into the connector together by arranging a pressure ring and an insertion ring in staggered positions, the pressure ring presses and positions the pressing gasket from above, and the insertion ring is embedded under the outer edge of the gasket at the wiring position of the connector, effectively positioning the terminal body in the connector, and the cable passes through the contoured flip shell and the contoured fixed shell and enters the sleeve part at the rear end of the terminal body. The cable restraint module always keeps coincidence with the axial line of the terminal body, which can effectively restrain part of the cable near the terminal body and straighten and fix the part of the cable, so that the part of the cable near the terminal body always remains in a stable and inactive state during service. The terminal body can only move after being pushed forward to allow the insertion ring to stagger the gasket in the connector, effectively avoiding the terminal body from being bent and deformed due to active collision at the crimping boundary in the connector, thereby improving the stability of the terminal body during service, so as to solve the problems raised in the above-mentioned background technology.

The structure content mentioned in the following embodiments is all referenced to the drawings of the specification.

[0024] Please refer to Figures 1 - 5 , in the embodiment of the present invention, a cold-pressed terminal for a connector includes a terminal body 1. A positioning and fastening module 2 is provided at the front end of the terminal body 1. The positioning and fastening module 2 includes a semi-circular bottom block 21, a semi-circular top block 22, a pressing ring 23, and an inserting ring 24. The semi-circular top block 22 and the semi-circular bottom block 21 are positioned one above the other at the front end of the terminal body 1. The pressing ring 23 and the inserting ring 24 are in an interleaved state. The pressing ring 23 is fixed above the terminal body 1 through the semi-circular top block 22 to press and position the lower pressing gasket from above. The inserting ring 24 is fixed below the terminal body 1 through the semi-circular bottom block 21 to be embedded below the outer edge of the gasket at the wiring position of the connector. A cable constraint module 3 is provided at the rear end of the terminal body 1. The cable constraint module 3 includes a profiling fixed shell 31, a profiling flipping shell 32, and an internal thread combination frame 33. The profiling flipping shell 32 is rotatably connected to the open side of the profiling fixed shell 31. The profiling fixed shell 31 is screwed and fixed to the rear end of the terminal body 1 through the internal thread combination frame 33 to position the cable constraint module 3 and make the cable constraint module 3 coincide with the axis of the terminal body 1, and to straighten and fix the wiring near the terminal body 1.

[0025] The sleeve part at the rear end of the terminal body 1 is used to connect the cable. The horizontal joint part at the front end of the terminal body 1 extends into the corresponding row groove inside the connector, is placed flat on the gasket in the row groove, and positions the terminal body 1 inside the corresponding row groove in the connector.

[0026] The front end of the terminal body 1 is provided with an alignment and fastening module 2, which is composed of a semicircular bottom block 21, a semicircular top block 22, a pressure ring 23 and an insert ring 24. The front end of the terminal body 1 is fixedly connected with a connecting block 26, the semicircular top block 22 is fixedly connected to the top of the connecting block 26, and the semicircular bottom block 21 is fixedly connected to the bottom of the connecting block 26, so that the semicircular top block 22 and the semicircular bottom block 21 are stably fixed one above and one below at the front end of the terminal body 1. The inner side walls of the semicircular top block 22 and the semicircular bottom block 21 are both located inside the outer edge of the horizontal joint part of the terminal body 1, so that the semicircular top block 22 and the semicircular bottom block 21 can effectively wrap the corresponding gasket from the outside, so as to effectively perform the alignment operation of the terminal body 1 in the connector. The pressure ring 23 is fixedly connected to the open end of the semicircular top block 22, the top of the pressure ring 23 is flush with the top of the semicircular top block 22, and the plug ring 24 is fixedly connected to the inner wall of the semicircular bottom block 21, and the bottom of the plug ring 24 is flush with the bottom of the semicircular bottom block 21, so that the pressure ring 23 and the plug ring 24 are stably positioned above and below the horizontal joint part of the terminal body 1. The pressure ring 23 and the plug ring 24 are in a staggered state, so that there is enough space between the pressure ring 23 and the plug ring 24 for the terminal body 1 to move into the connector. After the terminal body 1 enters the connector, the bottom of the plug ring 24 and the bottom of the semicircular bottom block 21 both move along the bottom of the corresponding groove of the connector, and the semicircular bottom block 21 clamps the outer wall of the gasket at the wiring position from the outside, and the plug ring 24 can be embedded below the outer edge of the gasket through the narrow angle part of the inner position, and can effectively hook the gasket at the wiring position in the connector to align and position the terminal body 1 in the connector. The movable pressing gasket can enter the inner side of the semi-dome block 22 from the gap space between the pressing ring 23 and the sleeve part of the terminal body 1. The semi-dome block 22 clamps the pressing gasket from the outside, and the pressing ring 23 presses and positions the pressing gasket from the top, which is convenient for the positioning and fixing of the pressing gasket, so that the operator can quickly operate the screws to fix the terminal body 1 in the connector.

[0027] The cable constraint module 3 is connected to the rear end of the terminal block body 1. The cable constraint module 3 is composed of a profiling fixed shell 31, a profiling flipping shell 32, and an internal thread combined frame 33. The profiling flipping shell 32 is rotatably connected to the open side of the profiling fixed shell 31. The internal thread combined frame 33 is screwed and fixed to the front end of the profiling fixed shell 31. The other end of the internal thread combined frame 33 is screwed and fixed to the outer side wall of the terminal block body 1, which is convenient for the overall connection and fixing operation of the cable constraint module 3 to the terminal block body 1, and can stably position the cable constraint module 3 at the rear end of the terminal block body 1. The rotation distance of the internal thread combined frame 33 at the rear end of the terminal block body 1 is fixed. After the cable constraint module 3 is positioned and connected to the rear end of the terminal block body 1, the cable constraint module 3 and the terminal block body 1 can always be kept in a state where their axis lines coincide. The profiling flipping shell 32 flips on the open side of the profiling fixed shell 31. After exposing the internal space of the profiling fixed shell 31, the cable is placed into the profiling fixed shell 31. The cable extends out from the front end inside the profiling fixed shell 31 and then enters the inside of the sleeve part of the terminal block body 1, which is convenient for placing the cable. After the cable placement is completed, the profiling flipping shell 32 is reset. A tightening sleeve 34 is fixedly connected to the front end of the profiling flipping shell 32. Operating the tightening sleeve 34 causes the tightening sleeve 34 to deform, so that the tightening sleeve 34 surrounds the profiling fixed shell 31 from the outside, effectively combining and fixing the profiling flipping shell 32 and the profiling fixed shell 31. The profiling flipping shell 32 and the profiling fixed shell 31 cooperate to tighten the cable near the terminal block body 1, achieving the effect of straightening and fixing the cable near the terminal block body 1.

[0028] The open end of the semi-circular bottom block 21 is fixedly connected with a connecting frame 25. The top of the connecting frame 25 is in close contact with the bottom of the terminal block body 1. The bottom of the connecting frame 25 is in contact with the bottom of the corresponding row groove of the connector. The rear end of the connecting frame 25 is fixedly connected with a filling plate 4. The top of the filling plate 4 is in close contact with the bottom of the terminal block body 1. The bottom of the filling plate 4 is flush with the bottom of the connecting frame 25. The filling plate 4 and the connecting frame 25 cooperate to effectively fill the gap space between the terminal block body 1 and the connector at the crimping boundary, increasing the coverage range of the terminal block body 1. The other end of the filling plate 4 is fixedly connected with a guiding seat 41. An annular groove 331 is provided at the end of the internal thread combined frame 33 screwed on the outer side wall of the terminal block body 1. The guiding seat 41 is snap-fitted into the annular groove 331. When the internal thread combined frame 33 rotates, the guiding seat 41 moves along the groove wall on the inner side of the annular groove 331 to ensure the stability of the rotation of the internal thread combined frame 33. At the same time, the guiding seat 41 can resist the internal thread combined frame 33 from the outside, restricting the rotation path of the internal thread combined frame 33 to effectively position the cable constraint module 3.

[0029] The connecting block 26 positions the semicircular top block 22 and the semicircular bottom block 21 one above and one below at the front end of the terminal body 1, so that when the terminal body 1 is placed in the connector, it can press against the corresponding gasket in the connector from the outside. The pressure ring 23 and the plug ring 24 in the staggered position extend into the connector together. The operator operates the terminal body 1 to make the plug ring 24 approach the gasket and gradually embed it under the outer edge of the gasket at the connector connection position, and the gasket is placed on the inner side of the semicircular top block 22. The pressure ring 23 presses and positions the gasket from the top, effectively positioning the terminal body 1 inside the connector. The cable passes through the profiling flip shell 32 and the profiling fixed shell 31, extends from the front end of the profiling fixed shell 31 and enters the sleeve part at the rear end of the terminal body 1. The profiling fixed shell 31 is positioned to position the cable restraint module 3 as a whole at the rear end of the terminal body 1. The cable restraint module 3 and the axis of the terminal body 1 always coincide with each other, which can effectively restrain part of the cable near the terminal body 1, and at the same time straighten and fix the part of the cable, so that the part of the cable near the terminal body 1 always remains in a stable and inactive state during the service process, and avoids the cable in the sleeve part of the terminal body 1 from being deflected by force. The terminal body 1 can only continue to move after the plug ring 24 is pushed forward to offset the gasket in the connector, so that the terminal body 1 and the cable can always maintain a stable horizontal connection state in the connector, so that the terminal body 1 will not be pulled by the rear cable during the connection and separation process and will move autonomously in the connector, which can effectively avoid the terminal body 1 from colliding at the crimping boundary in the connector and bending and deformation, improve the stability of the terminal body 1 in the service process, and ensure the long-term safe use of the terminal body 1.

[0030] The working principle of the present invention is as follows: the profiling flip shell 32 is rotated outward to expose the inner space of the profiling fixed shell 31, the cable is inserted into the profiling fixed shell 31, the cable passes through the front end of the profiling fixed shell 31 and enters the sleeve part of the terminal body 1, and after the profiling flip shell 32 is reset, the tightening sleeve 34 is operated to tighten the profiling flip shell 32 on the profiling fixed shell 31, tighten the cable inside the profiling fixed shell 31 and the profiling flip shell 32, and at the same time, the cable is straightened behind the terminal body 1, the operator operates the terminal body 1 to move toward the inside of the connector, the pressure ring 23 and the plug ring 24 in the staggered position are extended into the connector together, and the operator operates the wiring The terminal body 1 allows the plug ring 24 to approach the gasket and gradually embed under the outer edge of the gasket at the wiring position of the connector, and the gasket is pressed down to the inner side of the semi-dome block 22. The pressing ring 23 presses and positions the gasket from above, and positions the terminal body 1 inside the connector. The part of the cable close to the terminal body 1 always remains in a stable and inactive state during service. During the connection and separation process of the terminal body 1, the terminal body 1 is pushed forward to allow the plug ring 24 to offset the gasket in the connector before it can continue to move, so that the terminal body 1 will not be pulled by the rear-end cable and appear in the connector. Autonomous movement, allowing the terminal body 1 to serve stably in the connector.
