Description

Technical Field

[0001] This utility model relates to the field of terminal connector technology, and in particular to a press-type terminal connector. Background Technology

[0002] Press-fit terminal connectors are tool-free electrical connection accessories that do not require a screwdriver and rely on internal spring clips to clamp the wires. They are easy to operate and are widely used in lighting installations, household circuits, and industrial wiring scenarios.

[0003] Chinese invention patent application CN201510526437.3 discloses a terminal block with a snap-fit ​​structure, comprising a body, a conductive terminal, a metal spring, and a clamping block. The body includes a receiving groove and a stop block within it, a wire insertion hole, a clamping hole, and an adjacent hook. The wire insertion hole and the clamping hole communicate with the receiving groove, and the hook is elastically connected to the body. The hook has an extension rod, a contact block, and a latching portion disposed on the extension rod. The conductive terminal is disposed within the receiving groove and has a mating foot protruding from the body. The metal spring is disposed within the receiving groove and has an abutting end and a movable end. The abutting end contacts the conductive terminal, and the movable end is elastically disposed within the receiving groove. One side of the stop block corresponds to the abutting end. The clamping block is movably accommodated in the clamping hole and has a limiting block. The clamping block abuts against the movable end of the metal spring and engages with the latching portion through a locking point. This allows for quick and convenient wiring or replacement of cables.

[0004] However, when using this structure for wiring, the clamping block must first be pressed down, causing it to move inward and engage with the locking mechanism. Simultaneously, the metal spring is deformed by the clamping block. The cable is then inserted, and the locking mechanism is then moved to release the clamping block's restraint. The metal spring releases energy and returns to its original position, pushing the clamping block outward while simultaneously pressing against the cable. However, due to the connector's small overall size, the space for deforming the locking mechanism is very limited. It is difficult for operators to quickly apply force to the locking mechanism to deform it and release the clamping block's restraint, hindering rapid cable wiring or replacement operations.

[0005] Therefore, it is necessary to improve existing terminal connectors to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a push-button terminal connector that allows for quick wiring or replacement of cables, providing excellent cable fixation and easy, convenient operation.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a push-button terminal connector, comprising a body, conductive terminals, a metal spring, and a button. The body has an inner cavity, and the side of the body has a socket and an installation port communicating with the inner cavity. The conductive terminals are installed at the bottom of the inner cavity, and the conductive terminals have a pair of pins extending to the outside of the body. The metal spring is rotatably disposed in the inner cavity, and the metal spring includes a C-shaped rotating part and a transmission arm and a contact arm located at both ends of the C-shaped rotating part. The button is oscillatingly disposed at the installation port via a rotating shaft. One end of the button extends into the inner cavity and is linked to the transmission arm. When the button is oscillating, the button drives the C-shaped rotating part to rotate, causing the contact arm of the C-shaped rotating part to move toward or away from the conductive terminal.

[0008] By adopting the above technical solution, only a one-way push of the button is needed to simultaneously drive the metal spring contact arm to complete the opening or clamping action. After the cable is inserted, there is no need to operate the unlocking component separately. That is, there is no need to apply force to deform the hook in a narrow space to complete the unlocking as with existing technology products. With this design, the metal spring can directly swing with the button to quickly release or clamp the cable. The operation steps for wiring and replacement are simpler. Not only is the cable fixing effect good, but the operation is also very easy and convenient.

[0009] The present invention is further configured such that a support shaft is provided in the inner cavity of the main body, a rotating groove is formed between the outer circular surface of the support shaft and the inner wall of the inner cavity, the C-shaped rotating part is rotatably disposed in the rotating groove, and the inner wall of the inner cavity is also provided with a limiting surface for limiting the rotation stroke of the contact arm.

[0010] By adopting the above technical solution, the installation of the C-shaped rotating part can be positioned so that it can rotate stably with the support shaft as the rotation center.

[0011] The present invention is further configured such that the inner end of the button is provided with a first pawl and a second pawl, and a movable groove is formed between the first pawl and the second pawl, and the end of the transmission arm is movably disposed in the movable groove.

[0012] By adopting the above technical solution, the double claws at the inner end of the button cooperate to form a wrap-around movable groove, which restricts the transmission arm end of the metal spring to move in the groove. This not only improves the stability of power transmission between the button and the metal spring, but also ensures that the button toggles smoothly without jamming.

[0013] The present invention is further configured such that the end of the transmission arm is provided with an upwardly protruding bent protrusion and a downwardly protruding bent recess from the inside to the outside. When the outer end of the button is pressed down and abuts against the upper end of the main body, the end of the first pawl is embedded in the bent recess of the transmission arm, and the abutting arm presses the cable tightly onto the conductive terminal.

[0014] By adopting the above technical solution, the bent protrusion and bent concave part at the end of the transmission arm form a double-step positioning structure. When the button is pressed down to the locking position that abuts against the upper end of the main body, the first pawl can be accurately embedded in the bent concave part to form a stable locking limit, which avoids the button from being accidentally touched by external force and causing it to spring back and loosen, thus improving the reliability of the clamping state structure.

[0015] The present invention is further configured such that the upper end of the main body is provided with an inverted L-shaped elastic hook claw, and the button is provided with a hook claw groove. When the outer end of the button is pressed down and abuts against the upper end of the main body, the elastic hook claw is engaged in the hook claw groove.

[0016] By adopting the above technical solution, the inverted L-shaped elastic claw integrally formed at the upper end of the main body can directly engage with the claw groove of the button when the button is pressed down, forming a secondary elastic locking structure. Without the need for additional independent limiting parts, the button can be stably locked in the clamping position, effectively preventing the button from accidentally rebounding and loosening due to vibration or accidental contact.

[0017] The present invention is further configured such that the width of the elastic hook and the hook groove is less than half the width of the button, and the hook groove is provided on one side of the button.

[0018] By adopting the above technical solution, the elastic claw and claw groove are limited to one side of the button and the width is less than half of the button. This not only retains the stable elastic locking function, but also avoids the over-positioning jamming problem caused by double-sided symmetrical locking. When the button swings to unlock, the force deformation of the claw on one side changes smoothly, making it easier to disengage from the claw groove. The operating force required for unlocking is smaller, and the operating feel is greatly improved.

[0019] The present invention is further provided that the inner wall of the inner cavity is provided with positioning grooves for the two ends of the conductive terminals to be engaged.

[0020] By adopting the above technical solution, the conductive terminals can be positioned to ensure the stability of their installation.

[0021] The present invention is further configured such that the main body includes a base and a side cover, a plurality of positioning protrusions are provided on one side of the base, a plurality of positioning holes are provided on the side cover to form an interference fit with the positioning protrusions, and the inner cavity and the mounting port are formed between the base and the side cover.

[0022] By adopting the above technical solution, the main body adopts a split assembly structure, which not only facilitates injection molding, but also makes it easier to install conductive terminals, metal springs and buttons.

[0023] The present invention is further configured such that the base is provided with a plurality of positioning grooves on the other side of the positioning protrusion, the number of which is equivalent to the number of positioning protrusions, and the orthographic projections of the positioning grooves and the corresponding positioning protrusions on the side cover coincide.

[0024] By adopting the above technical solution, when multiple terminal connectors of the same specification are spliced ​​side by side, the positioning protrusions of adjacent connectors can be directly embedded into the positioning grooves on the corresponding sides, realizing quick alignment and splicing without clips, glue, or screws, which greatly improves the assembly efficiency of multi-row terminals.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example: As attached Figures 1-6The push-button terminal connector shown includes a body 1, conductive terminals 2, a metal spring 3, and a button 4. The body 1 has an inner cavity 5. The side of the body 1 has a socket 6 and a mounting opening 7 communicating with the inner cavity 5. A cable extends into the inner cavity 5 through the socket 6. The conductive terminals 2 are mounted at the bottom of the inner cavity 5 and have a pair of pins 8 extending to the outside of the body 1; that is, the bottom of the conductive terminals 2 has through holes for the pins 8 to pass through. The metal spring 3 is rotatably disposed within the inner cavity 5. The metal spring 3 includes a C-shaped rotating part 9 and a transmission arm 10 and abutting arm 11 located at both ends of the C-shaped rotating part 9. The button 4 is oscillating at the mounting port 7 via a rotating shaft 12. The button 4 has a shaft hole for inserting the rotating shaft 12. One end of the button 4 extends into the inner cavity 5 and is linked to the transmission arm 10. When the button 4 is oscillating, the button 4 drives the C-shaped rotating part 9 to rotate, causing the abutting arm 11 of the C-shaped rotating part 9 to move toward or away from the conductive terminal 2. Simply by tossing the button 4 in one direction, the contact arm 11 of the metal spring 3 can be simultaneously driven to open or clamp. More specifically, pressing down the button 4 causes the metal spring 3 to clamp the cable, while tossing up the button 4 causes the metal spring 3 to release the cable. After insertion, no additional unlocking mechanism is required. Unlike existing products, which require applying force to deform the hook in a confined space to unlock, this design allows the metal spring 3 to quickly release or clamp the cable as the button 4 swings. This simplifies the wiring and replacement process, resulting in better cable fixation and easier, more convenient operation.

[0029] As attached Figure 3 and attached Figure 4 As shown, a support shaft 13 is integrally formed in the inner cavity 5 of the main body 1. A rotating groove 14 is formed between the outer circular surface of the support shaft 13 and the inner wall of the inner cavity 5. The C-shaped rotating part 9 is rotatably disposed in the rotating groove 14. The inner wall of the inner cavity 5 is also provided with a limiting surface 15 for limiting the rotational stroke of the contact arm 11, that is, limiting the movement stroke of the contact arm 11 toward the conductive terminal 2. This design can position the installation of the C-shaped rotating part 9 so that it can rotate stably around the support shaft 13 as the rotation center.

[0030] As attached Figure 4 As shown, the inner end of the button 4 is integrally provided with a first pawl 16 and a second pawl 17, and a movable groove 18 is formed between the first pawl 16 and the second pawl 17. The end of the transmission arm 10 is movably disposed in the movable groove 18. The double pawls at the inner end of the button 4 cooperate to form a wrap-around movable groove 18, which restricts the end of the transmission arm 10 of the metal spring 3 to linkage within the groove. This not only improves the stability of power transmission between the button 4 and the metal spring 3, but also ensures that the button 4 can be turned smoothly without jamming.

[0031] As attached Figure 4As shown, the transmission arm 10 has an upwardly protruding bent protrusion 19 and a downwardly protruding bent recess 20 at its end, from the inside to the outside. When the outer end of the button 4 is pressed down and abuts against the upper end of the main body 1, the end of the first pawl 16 is embedded in the bent recess 20 of the transmission arm 10, and the contact arm 11 presses the cable tightly onto the conductive terminal 2. The bent protrusion 19 and the bent recess 20 at the end of the transmission arm 10 form a double-step positioning structure. When the button 4 is pressed down to the locking position abutting against the upper end of the main body 1, the first pawl 16 can be accurately embedded in the bent recess 20, forming a stable locking limit, preventing the button 4 from being accidentally pressed by external force and rebounding and loosening, thus improving the reliability of the clamping structure.

[0032] As attached Figure 4 As shown, the upper end of the main body 1 is integrally provided with an inverted L-shaped elastic claw 21, and the button 4 is provided with a claw groove 22. When the outer end of the button 4 is pressed down and abuts against the upper end of the main body 1, the elastic claw 21 is engaged in the claw groove 22. When the button 4 is pushed upward with force, the elastic claw 21 can automatically release out of the claw groove 22. The inverted L-shaped elastic claw 21 integrally formed on the upper end of the main body 1 can directly engage in the claw groove 22 of the button 4 when the button 4 is pressed down, forming a secondary elastic locking structure. Without the need for additional independent limiting parts, the button 4 can be stably locked in the clamping position, effectively preventing the button 4 from accidentally rebounding and loosening due to vibration or accidental contact.

[0033] The elastic claw 21 and claw groove 22 are less than half the width of the button 4, and the claw groove 22 is located on one side of the button 4, i.e., the claw groove 22 and the elastic claw 21 are offset. By confining the elastic claw 21 and claw groove 22 to one side of the button 4 and making their width less than half that of the button 4, a stable elastic locking function is retained, while avoiding the over-positioning and jamming problem caused by double-sided symmetrical locking. When the button 4 swings to unlock, the claw on one side changes shape smoothly under force, making it easier to disengage from the claw groove 22. The operating force required for unlocking is reduced, and the operating feel is greatly improved.

[0034] As attached Figure 3 and attached Figure 4 As shown, the inner wall of the inner cavity 5 is provided with positioning slots 23 for the two ends of the conductive terminal 2 to be inserted. The positioning slots 23 can position the conductive terminal 2 to ensure its stable installation.

[0035] As attached Figure 1 , 2As shown in Figure 5, the main body 1 includes a base 24 and a side cover 25. The base 24 has multiple positioning protrusions 26 on one side, and the side cover 25 has multiple positioning holes 27 that form an interference fit with the positioning protrusions 26. The inner cavity 5 and the mounting opening 7 are formed between the base 24 and the side cover 25. The main body 1 adopts a split-type assembly structure, which not only facilitates injection molding but also makes it easier to install the conductive terminals 2, metal springs 3, and pressure buttons 4.

[0036] As attached Figure 1 , 2 As shown in Figure 5, the base 24 has multiple positioning grooves 28 on the other side corresponding to the positioning protrusions 26, with a number equal to the number of positioning protrusions 26. The orthographic projections of the positioning grooves 28 and the corresponding positioning protrusions 26 on the side cover 25 coincide. When multiple terminal connectors of the same specification are spliced ​​side by side, the positioning protrusions 26 of adjacent connectors can be directly embedded into the positioning grooves 28 on the corresponding side, realizing quick alignment and splicing without clips, glue, or screws, which greatly improves the assembly efficiency of multi-row terminals.
