Description

Technical Field

[0001] The invention relates to the field of connectors, in particular to a locking connector. Background Art

[0002] A connector is a device used to connect two active devices. It can transmit current or signals. It plays a vital role in various electronic devices, ensuring smooth signal and power transmission between various components. It is an indispensable component in electronic devices.

[0003] At present, connectors are mostly connected to wires in a plug-in manner, and a wire locking structure is arranged inside the connector to fix the wires. The existing Chinese public patent document: CN117438837A discloses a spring-cage locking electrical connector, which has two springs, a wire locking spring and a fixed spring. The fixed spring is connected to the terminal block, and the fixed spring is clamped with the inner wall of the insulating shell, so that the terminal block, the wire locking spring and the fixed spring are fixed relative to the insulating shell through the fixed spring. Since the fixed spring is fixedly connected to the terminal block, the fixed spring is stably arranged, thereby improving the reliability of the assembly of the terminal block, the wire locking spring and the fixed spring with the plastic plug-in body. Although the wire can be firmly fixed, if this type of connector is used in power-on detection or portable equipment, it is necessary to frequently plug and unplug the wire. Since the spring has elastic fatigue, the elasticity of the spring will be reduced in the case of long-term plugging and unplugging, which will reduce the fixing effect of the wire and make it easy to loosen.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions 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 of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Example 1: Please refer to Figure 1-Figure 8 , a locking connector shown in the figure includes a housing 1 and a wiring plug 2 arranged above the housing 1, a docking port 3 for limiting the insertion of the wiring plug 2 is provided on the top of the housing 1, a docking rod 4 matching the wiring plug 2 is fixedly installed on the bottom inner wall of the docking port 3, the wiring plug 2 is inserted into the docking port 3 and docked with the docking rod 4, three clamping rollers 5 equidistantly distributed on the inner side of the docking port 3 are provided on both sides of the wiring plug 2, which are used to clamp and fix the wiring plug 2, the outer side of the clamping roller 5 is an arc-shaped concave structure, which increases the contact surface between the clamping roller 5 and the wiring plug 2, the outer side of the clamping roller 5 is made of rubber, and the outer side of the clamping roller 5 is provided with a plurality of equidistantly distributed anti-slip strips 26 to increase the friction between the wiring plug 2 and the wiring plug 2; it also includes: a locking mechanism for firmly positioning the wiring plug 2, the locking mechanism is installed on the inner side of the docking port 3; an unlocking mechanism for quickly unlocking the wiring plug 2, the unlocking mechanism is installed on the outer side of the housing 1; a quick release mechanism for quickly replacing the clamping roller 5, and the quick release mechanism is installed on the inner side of the docking port 3.

[0031] The locking mechanism includes two positioning plates 6 symmetrically arranged on both sides of the clamping roller 5, and a ratchet 7 is fixedly installed on the side of the positioning plate 6 away from the clamping roller 5. When the wiring plug 2 is inserted downward into the docking port 3, it contacts the clamping roller 5, which can drive the clamping roller 5 to rotate and drive the ratchet 7 to rotate synchronously. A support plate 8 is rotatably installed on the side of the ratchet 7 away from the positioning plate 6. The end of the support plate 8 away from the ratchet 7 is fixedly connected to a mounting plate 9. A sliding rod 10 is slidably installed on the outer side of the mounting plate 9. A latching tooth 11 matching the ratchet 7 is fixedly installed on the end of the sliding rod 10 away from the mounting plate 9. The latching tooth A spring 12 is fixedly installed between 11 and the mounting plate 9. The elasticity of the spring 12 is used to make the latch tooth 11 press against the ratchet 7 to realize the unidirectional rotation of the ratchet 7. A fixing plate 13 is arranged on both sides of the housing 1. A groove for limiting and inserting the fixing plate 13 is provided on both sides of the housing 1. The fixing plate 13 is docked with the groove of the housing 1 through four bolts 25, which is convenient for installing and removing the fixing plate 13. Three positioning plates 14 that are respectively on the same horizontal line with the three clamping rollers 5 are fixedly installed on the outer side of the fixing plate 13. The mounting plate 9 is installed on the inner side of the positioning plate 14;

[0032] When the staff inserts the wiring plug 2 into the docking port 3 on the housing 1, the outer side of the wiring plug 2 moves downward along the outer sides of the six clamping rollers 5, and the friction between the clamping rollers 5 and the wiring plug 2 is used to make the wiring plug 2 drive the clamping rollers 5 to rotate in the direction of the wiring plug 2. The clamping rollers 5 can drive the ratchet 7 to rotate through the positioning plate 6, and when the ratchet 7 rotates, the ratchet 7 pushes the latching teeth 11 to move, so that the latching teeth 11 compress the spring 12. When the wiring plug 2 and the docking rod 4 are docked, the rebound force of the spring 12 is used to lock the latching teeth 11 to the ratchet 7, and the unidirectional rotation of the ratchet 7 makes it difficult for the wiring plug 2 to be pulled out upward, so that the clamping rollers 5 can position the wiring plug 2, and the firmness between the wiring plug 2 and the docking port 3 is improved, thereby achieving a quick fixation effect.

[0033] The unlocking mechanism includes an insert frame 15 fixedly mounted on the end of the slide bar 10 away from the latch tooth 11, the outer side of the insert frame 15 contacts the outer side of the positioning plate 14, a push plate 16 is provided on the side of the fixed plate 13 away from the housing 1, an L-shaped insert plate 17 is slidably mounted on the inner side of the insert frame 15, the width of the inner side of the insert frame 15 is twice the width of the L-shaped insert plate 17, so that the L-shaped insert plate 17 can move on the inner side of the insert frame 15, the length of the inner side of the insert frame 15 is greater than the length of the L-shaped insert plate 17, the end of the L-shaped insert plate 17 away from the insert frame 15 is fixedly mounted on the outer side of the push plate 16, and a push plate 18 is fixedly mounted on the inner side of the insert frame 15, and the outer side of the push plate 18 is fixedly mounted on the outer side of the L-shaped insert plate 17 away from the fixed One side of the plate 13 is in contact with each other, and the contact surfaces of the push plate 18 and the L-shaped plug plate 17 are both inclined structures. When the L-shaped plug plate 17 moves downward, it can push the plug frame 15 to move through the push plate 18, so that the slide bar 10 pulls the latch tooth 11 away from the ratchet 7. The fixed plate 13 and the push plate 16 are fixedly installed on one side corresponding to the vertically distributed positioning strips 19, and a plurality of springs 20 equidistantly distributed are fixedly installed between the two positioning strips 19 to facilitate the reset of the push plate 16. The positioning plate 14 is fixedly installed on the side away from the support plate 8 with two symmetrically distributed guide strips 28. The two guide strips 28 are respectively in contact with the two sides of the plug frame 15 to provide guidance for the movement of the plug frame 15.

[0034] When it is necessary to pull out the wiring plug 2 from the docking port 3, the staff can push the two push plates 16 downward, so that the push plates 16 drive the L-shaped plug plate 17 to move along the inner side of the insertion frame 15, and the inclined surface of the end of the L-shaped plug plate 17 moves along the inclined surface of the abutment plate 18, so that the L-shaped plug plate 17 pushes the insertion frame 15 to move between the two guide strips 28 through the abutment plate 18, and the insertion frame 15 can pull the locking tooth 11 away from the ratchet 7 through the sliding rod 10 to release the lock of the ratchet 7, and the ratchet 7 can rotate in the opposite direction of the wiring plug 2, and the staff can pull out the wiring plug 2 from the docking port 3, making it easier to pull out the wiring plug 2 and preventing greater wear on the docking port 3, thereby achieving the effect of quickly pulling out the wiring plug 2.

[0035] Working principle: First, the staff inserts the wiring plug 2 into the docking port 3 on the shell 1, and the outer side of the wiring plug 2 moves downward along the outer sides of the six clamping rollers 5, and the outer side of the wiring plug 2 presses against the outer sides of the clamping rollers 5, so that the wiring plug 2 drives the clamping rollers 5 to rotate in the direction of the wiring plug 2 while moving downward, and the clamping rollers 5 drive the positioning plate 6 to rotate synchronously, so that the positioning plate 6 drives the ratchet 7 to rotate, and at the same time, the ratchet 7 pushes the latch teeth 11 to move, so that the latch teeth 11 push the spring 12 to compress, and then, the bottom of the wiring plug 2 docks with the docking rod 4 to complete the docking of the wiring plug 2 and the docking port 3. At this time, the ratchet 7 stops rotating, and the spring 12 pushes the latch teeth 11 to insert into the tooth groove of the ratchet 7, so that the ratchet 7 cannot rotate in the opposite direction, which can provide resistance to the upward pulling out of the clamping rollers 5 for the wiring plug 2, making it difficult for the wiring plug 2 to be pulled out from the docking port 3, and realizing the connection between the wiring plug 2 and the docking port When the staff needs to unplug the wiring plug 2, the staff pushes the two push plates 16 downward, and the push plates 16 drive the multiple L-shaped plug plates 17 to move along the inner side of the corresponding insertion frame 15, so that the inclined surface of the end of the L-shaped plug plate 17 moves along the inclined surface of the abutment plate 18 in the insertion frame 15, and the L-shaped plug plate 17 pushes the insertion frame 15 away from the fixed plate 13 along the two guide strips 28 through the abutment plate 18. At this time, the insertion frame 15 drives the slide bar 10 to move synchronously, so that the slide bar 10 pulls the card tooth 11 away from the ratchet 7, and releases the lock of the ratchet 7. As a result, the staff can quickly pull the wiring plug 2 upward from the docking port 3, thereby achieving the effect of firm docking and quick disassembly, which is convenient for the wiring plug 2 to dock with the docking port 3 repeatedly, and the positioning of the wiring plug 2 by the clamping roller 5 will not cause greater extrusion to the wiring plug 2, thereby improving the durability of the wiring plug 2.

[0036] Example 2: Please refer to Figure 2-Figure 6 , this embodiment further explains the first embodiment, the quick release mechanism shown in the figure includes an insert block 21 fixedly mounted on the side of the positioning plate 6 away from the ratchet 7, the insert block 21 is a prismatic structure, both sides of the clamping roller 5 are fixedly mounted with mounting plates 22, the outer side of the mounting plate 22 is provided with a slot for the insert block 21 to limit the insertion, so as to facilitate the installation of the clamping roller 5, and the positioning plate 6 is driven to rotate by the insert block 21, the interior of the positioning plate 14 is provided with a cavity for the mounting plate 9 to limit the sliding, and the outer side of the positioning plate 14 is provided with a slot ... inner side of the positioning plate 14 is provided with a slot for the mounting plate 9 to limit the sliding, and the outer side of the positioning plate 14 is provided with a slot for the mounting plate 9 to limit the sliding, and the inner side of the positioning plate 14 is provided with a slot for the mounting plate 9 to limit the sliding, and the outer side of the positioning plate 14 is provided with a slot for the mounting plate 9 to limit the sliding, and the inner side of the positioning plate 14 is provided with a slot for the mounting plate 9 to limit the sliding, and the inner side of the positioning plate 14 is provided with a slot for the mounting plate 9 to limit the sliding, and the inner side of the positioning plate 14 is provided with a slot for the mounting plate 9 to The sliding hole of the cavity is docked, and the inner side of the sliding hole contacts the outer side of the support plate 8. The size of the sliding hole is smaller than the size of the cavity to prevent the mounting plate 9 from sliding out of the cavity. The width of the cavity is greater than the length of the plug 21. Two symmetrically distributed guide rods 23 are fixedly installed on the inner side of the cavity of the positioning plate 14. The guide rods 23 slide through the mounting plate 9. A spring three 24 is arranged on the outer side of the guide rod 23. The spring three 24 is fixedly installed between the mounting plate 9 and the inner side of the cavity of the positioning plate 14 to facilitate the movement and reset of the mounting plate 9.

[0037] In this embodiment: Taking into account that the wiring plug 2 and the docking port 3 will cause certain wear and tear on the clamping roller 5 when they are docked and unplugged for a long time, the staff can remove the fixing plate 13 from the shell 1 and pull the two support plates 8 away from each other, so that the support plate 8 drives the mounting plate 9 to move along the cavity of the positioning plate 14, compressing the spring three 24. At the same time, the support plate 8 drives the ratchet 7 and the positioning plate 6 to move synchronously, so that the positioning plate 6 pulls the plug block 21 out of the slot on the mounting plate 22, and the clamping roller 5 can be taken out. When installing a new clamping roller 5, the slots on the mounting plate 22 on both sides of the clamping roller 5 are aligned with the two plug blocks 21, and the resilience of the spring three 24 is used to insert the plug block 21 into the slot of the mounting plate 22, so that the clamping roller 5 can be quickly installed, thereby achieving the effect of improving the durability of the docking port 3 and the wiring plug 2.

[0038] Example 3: Please refer to Figure 4-Figure 8 This embodiment further illustrates other embodiments. A guide block 27 is fixedly installed on the outer side of the latch 11 in the figure. A sliding cavity is provided on the outer side of the support plate 8 for the guide block 27 to limit the sliding movement, providing support for the movement of the latch 11. A plurality of strip-shaped grooves distributed evenly spaced are provided on the side of the push plate 16 away from the positioning bar 19, which is convenient for pushing the push plate 16 to move. A magnet block 29 is fixedly installed on the corresponding side of the two insertion frames 15. The contact surfaces of the two magnet blocks 29 are respectively positive and negative, which is convenient for resetting the two insertion frames 15. A pull ring 30 is fixedly installed on the side of the support plate 8 away from the ratchet 7, which is convenient for pulling the support plate 8 to move.

[0039] In this embodiment: when the latch 11 moves, it can drive the guide block 27 to move along the sliding cavity on the outer side of the support plate 8, provide guidance for the movement of the latch 11, and provide auxiliary support for the latch 11 to ensure that the latch 11 locks the ratchet 7. When the staff pushes the push plate 16 to move, it can contact the strip groove on the outer side of the push plate 16 to prevent slipping. The two insertion frames 15 can be positioned by adsorbing each other through the magnet block 29, which is convenient for the two L-shaped insertion plates 17 to push the two insertion frames 15 to move synchronously. Moreover, when the two insertion frames 15 contact each other, the mounting plate 9 can be against the inner side of the cavity of the positioning plate 14, thereby improving the reset speed of the mounting plate 9, facilitating the rapid installation between the positioning plate 6 and the clamping roller 5, and when pushing the mounting plate 9 to move, the staff can pull the support plate 8 to move through the two pull rings 30, thereby improving the convenience of disassembling the clamping roller 5.
