Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically a connector with a locking function. Background Technology

[0002] Connectors, also known as plugs and sockets, are key basic components in electronic devices used to realize the transmission of electrical signals and power. Their core function is to build or disconnect circuit connections by plugging and unplugging plugs and sockets. They are widely used in consumer electronics, industrial control, power systems, communication networks, automotive electronics and aerospace fields.

[0003] Connectors consist of a male and a female connector, and most male and female connectors on the market are fixed together with bolts; for example:

[0004] A Chinese patent discloses a stable secondary connector (authorization announcement number CN220873881U). The patented technology is as follows: when connector block A and connector block B are connected, the plug is inserted into the slot, and the connecting blocks can be connected and fixed by using bolts that mate with the bolt holes.

[0005] A Chinese patent discloses a positioning and installation connector plug hardware connector (authorization announcement number CN216214500U). The patented technology: by setting threaded tubes and threaded rods, it can stably connect and fix the male and female connectors, avoiding shaking.

[0006] This type of connection has certain drawbacks: the connection or disconnection process must be carried out with the help of tools (such as wrenches, screwdrivers, or manual rotation of specific parts), which is relatively troublesome and cannot achieve quick plugging and unplugging by hand. This not only reduces the ease of use, but is especially inconvenient in situations where frequent plugging and unplugging is required or space is limited. It also increases the risk of loose connection or damage to parts due to improper tool operation. Utility Model Content

[0022] Please see Figure 1 and Figure 2 In this embodiment of the present invention, a connector with a locking function includes a male connector 1 and a female connector 2 distributed on the left and right. A support frame 3 is fixedly sleeved on the opposite outer ends of the male connector 1 and the female connector 2. Multiple insertion rods 4 are fixedly connected through the male connector 1 in the left and right direction. A wire sleeve 5 is fixedly connected to the right side surface of the female connector 2, and multiple insertion tubes 6 are fixedly connected to the right side surface of the inside of the female connector 2. The number of insertion rods 4 and insertion tubes 6 is equal, and the insertion rods 4 are directly opposite the insertion tubes 6. Both insertion rods 4 and insertion tubes 6 are conductive components. A wire 7 is fixedly connected to the right end of the insertion tube 6. The wire 7 movably passes through the right end of the female connector 2, and the wire 7 is located inside the wire sleeve 5.

[0023] When the male head 1 and the female head 2 are fitted together, the insertion rod 4 is inserted into the inside of the insertion tube 6, and the two support frames 3 are fitted together.

[0024] The left end of the plug 4 (the end located outside the male connector 1) is soldered to an external device, and the ends of the multiple wires 7 away from the female connector 2 are connected to another external device;

[0025] The materials of both the insertion rod 4 and the insertion tube 6 are preferably copper alloys;

[0026] The wire 7 includes a conductive core and an insulating sheath.

[0027] exist Figure 1 , Figure 3 and Figure 4In the middle: Insertion holes 8 are provided inside both the front and rear ends of the support frame 3. Locking mechanisms 9 are provided on both the front and rear surfaces of the male head 1 and the female head 2. The locking mechanism 9 includes a rack 10 and a gear 11 located to the lower right of the rack 10. The rack 10 moves through the insertion hole 8 and meshes with the gear 11. A fixing seat 12 is fixedly connected to the left end of the rack 10, and the fixing seat 12 is fixedly connected to one side surface of the male head 1. A fixing rod 13 is fixedly connected inside the gear 11. C-shaped seats 14 are rotatably sleeved on both the front and rear ends of the fixing rod 13. The gear 11 is located inside the C-shaped seat 14. A fixing rod 13 is fixedly connected to the right end of the C-shaped seat 14. Seat 2 15 is fixedly connected to one side surface of the female head 2. A ratchet 16 is fixedly sleeved on the external end of the fixing rod 13 away from the female head 2. A locking element 17 is provided on the side surface of the C-shaped seat 14 away from the female head 2 and on the side of the fixing rod 13. The locking element 17 includes a spring 18. A positioning block 19 is fixedly connected to the end of the spring 18 away from the fixing rod 13, and a pawl 20 is fixedly connected to the end of the spring 18 near the fixing rod 13. The pawl 20 is attached to the ratchet 16. A positioning rod 21 is rotatably connected to the upper end of the pawl 20. The positioning block 19 and the positioning rod 21 are both fixedly connected to the side surface of the C-shaped seat 14 away from the female head 2.

[0028] Pawl 20 engages with ratchet 16, allowing ratchet 16 and fixed rod 13 to rotate clockwise normally, but not counterclockwise. Pulling pawl 20 away from ratchet 16 allows ratchet 16 and fixed rod 13 to rotate counterclockwise.

[0029] When male connector 1 and female connector 2 are inserted, rack 10 passes through the insertion hole 8 from left to right. When it encounters gear 11, it drives it to rotate clockwise until male connector 1 and female connector 2 are completely fitted together, thus completing the insertion of male connector 1 and female connector 2.

[0030] When the male head 1 and the female head 2 are fully engaged, the right end of the rack 10 will not touch the right end of the C-type seat 14.

[0031] The working principle of this utility model is as follows: When the male connector 1 and the female connector 2 need to be connected together, their opposite end faces are brought close together. The insertion rod 4 on the male connector 1 will be inserted into the corresponding insertion tube 6 on the female connector 2 to achieve electrical connection. At the same time, the support frames 3 on the male connector 1 and the female connector 2 are in contact with each other. During this process, the rack 10 fixed to the side of the male connector 1 will pass through the insertion hole 8 on the support frame 3 and mesh with the gear 11 fixed to the side of the female connector 2, driving the gear 11 and its internal fixing rod 13 to rotate clockwise. The ratchet 16 on the fixing rod 13 will also rotate clockwise. At this time, the pawl 20 is under the action of the spring 18. The ratchet 16 is engaged, allowing it to rotate clockwise but not counterclockwise, thus achieving one-way locking after insertion. When it is necessary to separate the male head 1 and the female head 2, two fingers should be used to simultaneously pull the pawls 20 on both sides outward to overcome the spring force of the spring 18 and move them away from the ratchet 16, thus releasing the restriction on the counterclockwise rotation of the ratchet 16. Keep this state in place, and at the same time pull the female head 2 to drive the gear 11 and the ratchet 16 to rotate counterclockwise. The rack 10 then exits from the insertion hole 8 to the left, thus separating the female head 2 from the male head 1. At the same time, the insertion rod 4 is pulled out from the insertion tube 6.
