Description

Technical Field

[0001] This utility model relates to the field of cable connector technology, and in particular to a female power cable connector for a wire-to-board connection. Background Technology

[0002] Connectors are mainly used in applications with high voltage requirements, such as servers / communication equipment. However, existing wire-to-board power connectors have low configuration and poor application flexibility. To address these issues, we propose a female power cable connector for wire-to-board connections. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, one of the objectives of this utility model is to provide a female power cable connector for a wire-to-board connection.

[0004] One of the objectives of this utility model is achieved through the following technical solution:

[0005] A female power cable connector for a wire-to-board connection includes a cable connector body. The cable connector body includes a housing, and the housing has four fixing slots arranged in a rectangular array. Each fixing slot has a terminal inside its cavity, and a cable is riveted to the terminal. A heat shrink tubing is fitted at the riveting point between each terminal and the cable. The top and bottom of the housing have two symmetrically arranged slots, and the inner cavity of each slot has a limiting fastener for fixing the terminal. A dustproof component is provided on the right side of the housing, and a waterproof component is provided on the upper surface of the housing.

[0006] Furthermore, the dustproof component includes an end cap, which is slidably fitted onto the right side of the outer shell. The end cap is provided with four elastic sleeves corresponding to the positions of the fixing slots. The four cables are slidably inserted through the inner cavities of the four elastic sleeves. Insert rods are slidably connected to both the front and rear sides of the end cap, and a fixing ring is fixedly connected to the end of the insert rod away from the end cap. Springs are fitted onto the outer walls of both insert rods, and the two ends of the springs are fixedly connected to the fixing ring and the end cap, respectively. Positioning holes are symmetrically opened on the front and rear sides of the outer shell, and the opposite ends of the two insert rods are respectively inserted into the inner cavities of adjacent positioning holes.

[0007] Furthermore, the elastic sleeve is made of insulating material, and the inner wall of the elastic sleeve can be fitted to fit the outer wall of the cable.

[0008] Furthermore, the waterproof component includes an n-shaped sliding cover plate, which is slidably connected to the top of the housing. The n-shaped sliding cover plate has sliders on both the front and rear sides of its inner cavity. The housing has symmetrically opened grooves on both the front and rear sides that are adapted to the sliders, and the two sliders are slidably connected to the inner cavities of adjacent grooves.

[0009] Furthermore, a threaded hole is provided at the middle position of the n-shaped sliding cover, and a matching locking screw is threaded into the inner cavity of the threaded hole. A knob and an insulating rubber pad are respectively fixedly connected to the upper and lower ends of the locking screw.

[0010] Furthermore, elastic fasteners are symmetrically arranged on both the front and rear sides of the outer casing.

[0011] Furthermore, the outer wall of the knob is provided with anti-slip texture.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. By setting up the shell, terminals, cables, heat shrink tubing and limit fasteners, the limit fasteners, terminals and other components are all unified into one structure, which makes the production of parts and material control simpler. On the other hand, it also has advantages for the subsequent expansion of the product. For example, in this case it is a 2x2 specification, which can be expanded laterally to 2x3, 2x4 and other specifications. Only the shell needs to be modified. The fasteners, terminals and other components can be reused without any changes, which helps to reduce production costs.

[0014] 2. By riveting the terminals to the cable and covering the riveting with heat shrink tubing, the riveted cable terminals are then inserted into the housing. After insertion, the limiting clips are inserted into the slots to lock the terminals in place, thus quickly completing the assembly of the cable connector and improving the ease of assembly and disassembly of the cable connector.

[0015] 3. The design, including the end cap, elastic sleeve, insert rod, fixing ring, spring, and positioning hole, allows the cable to pass through the elastic sleeve before connecting to the terminal. By placing the end cap on the right side of the housing and inserting the insert rods on both sides into the adjacent positioning hole, the end cap can be secured to the housing, thus sealing the fixing groove and preventing external dust from penetrating into the inner cavity of the fixing groove and causing a short circuit in the connector. Furthermore, the design, including the n-shaped sliding cover, slider, slide groove, locking screw, knob, and insulating pad, allows the female cable connector to be connected to the male connector on the board end. By pushing the n-shaped sliding cover to the connection gap between the two, water can be blocked from the connection gap, and the slot can be sealed to prevent water from penetrating into the cable connector, thus improving the safety of the cable connector.

[0025] This utility model provides the following technical solution:

[0026] Example 1, please refer to Figure 1 and Figure 2 :

[0027] A female power cable connector for a wire-to-board connection includes a cable connector body 1. The cable connector body 1 includes a housing 11, and the housing 11 has four fixing slots 101 arranged in a rectangular array. Each fixing slot 101 has a terminal 12 in its inner cavity, and a cable 13 is riveted to the terminal 12. A heat shrink tubing 14 is sleeved at the riveting joint between each terminal 12 and the cable 13. The top and bottom of the housing 11 have two symmetrically arranged slots 102, and the inner cavity of the slots 102 is slidably inserted with a limiting fastener 15 for fixing the terminal 12.

[0028] The front and rear sides of the outer shell 11 are symmetrically provided with elastic fasteners 16, so that when the female cable connector is inserted into the board connector, the elastic fasteners 16 engage with the fastening groove structure on the board connector, which fixes and holds the cable connector, effectively preventing the cable connector from falling off. When it is necessary to remove the connector, simply press the elastic fasteners 16 on both sides and pull backward to remove the cable connector.

[0029] Working principle: In use, firstly, the terminal 12 is riveted to the cable 13, and heat shrink tubing 14 is fitted over the riveted joint. Next, the terminal 12 with the riveted cable 13 is inserted into the fixing groove 101 in the housing 11. After insertion, the limiting latch 15 is inserted into the latch slot 102, thereby locking the terminal 12 in place and quickly completing the assembly of the cable connector. This improves the ease of assembly and disassembly of the cable connector. Through the design of the housing 11, terminal 12, cable 13, heat shrink tubing 14, and limiting latch 15, these components are unified into a single structure, simplifying component production and material control. Furthermore, it offers advantages for future product expansion; for example, in this case, it is a 2x2 specification, which can be laterally expanded to 2x3, 2x4, and other specifications. Only the outer shell 11 needs to be modified. The limiting buckle 15, terminal 12 and other components can be reused without any changes, which helps to reduce production costs. When two circuit board interfaces that are far apart in the system need to conduct current, they can usually be connected by a cable connector. This cable connector is compatible with the existing board connector. During the insertion process, the cable connector can smoothly achieve mating and conduction and transmit current through its own guiding action with the board connector. With the setting of the elastic buckle 16, when the female cable connector is mated with the board connector, the elastic buckle 16 engages with the buckle groove structure on the board connector, which plays a role in fixing and holding the cable connector and effectively prevents the cable connector from falling off. When it is necessary to remove the connector, simply press the elastic buckles 16 on both sides and pull backward to remove the cable connector.

[0030] Example 2, please refer to Figure 3 and Figure 4 :

[0031] The right side of the outer casing 11 is provided with a dustproof component 2, and the upper surface of the outer casing 11 is provided with a waterproof component 3.

[0032] The dustproof component 2 includes an end cap 21, which is slidably fitted onto the right side of the outer shell 11. The end cap 21 is provided with four elastic sleeves 22 corresponding to the positions of the fixing grooves 101. Four cables 13 are slidably inserted through the inner cavities of the four elastic sleeves 22. Insert rods 23 are slidably connected to both the front and rear sides of the end cap 21, and a fixing ring 24 is fixedly connected to the end of the insert rod 23 away from the end cap 21. Springs 25 are fitted onto the outer walls of the two insert rods 23, and the two ends of the springs 25 are fixedly connected to the fixing ring 24 and the end cap 21, respectively. Positioning holes 103 are symmetrically opened on the front and rear sides of the outer shell 11. The opposite ends of the two insert rods 23 are respectively inserted into the inner cavities of the adjacent positioning holes 103. The elastic sleeves 22 can fit tightly against the outer walls of the cables 13, thereby preventing external dust from penetrating into the inner cavity of the outer shell 11.

[0033] The elastic sleeve 22 is made of insulating material, and the inner wall of the elastic sleeve 22 can be fitted to the outer wall of the cable 13 to improve the insulation of the end cap 21.

[0034] The waterproof component 3 includes an n-shaped sliding cover plate 31, which is slidably connected to the top of the housing 11. Slider 35 is provided on both the front and rear sides of the inner cavity of the n-shaped sliding cover plate 31. Slide grooves 104 adapted to the slider 35 are symmetrically opened on both the front and rear sides of the housing 11. The two sliders 35 are slidably connected to the inner cavities of the adjacent slide grooves 104. With the setting of the n-shaped sliding cover plate 31, the slot 102 can be waterproofed without affecting the disassembly and assembly of the limit buckle 15. In addition, after the female cable connector and the board male connector are connected, the gap between the two can be covered to improve the anti-permeability effect.

[0035] A threaded hole 301 is provided in the middle of the n-shaped sliding cover plate 31, and a matching locking screw 32 is threadedly connected to the inner cavity of the threaded hole 301. A knob 33 and an insulating rubber pad 34 are fixedly connected to the upper and lower ends of the locking screw 32, respectively. The outer wall of the knob 33 is provided with anti-slip texture. By turning the knob 33, the locking screw 32 can be rotated and the insulating rubber pad 34 can be moved up and down. Thus, after the position of the n-shaped sliding cover plate 31 is adjusted, it can be locked on the outer wall of the outer shell 11, improving the stability of use.

[0036] Working principle: In use, firstly, the cable 13 is passed through the four elastic sleeves 22 in sequence and riveted to the terminal 12. After the cable connector is assembled, the end cap 21 is fitted onto the right side of the outer shell 11. By inserting the two plugs 23 into the inner cavities of the adjacent positioning holes 103 at opposite ends, the end cap 21 can be locked onto the outer shell 11, improving the dustproof effect on the inner cavity of the fixing groove 101. After connecting the cable connector to the board-end male connector, the n-shaped sliding cover 31 can be pushed close to the board-end male connector, so that the n-shaped sliding cover 31 can cover the connection gap between the board-end male connector and the female cable connector, and simultaneously cover the slot 102. By turning the knob 33 and driving the locking screw 32 to move downward, the insulating pad 34 can be driven to stick tightly to the outer wall of the outer shell 11, thereby achieving the purpose of locking the n-shaped sliding cover 31. By improving the waterproof performance of the cable connector, the safety of the cable connector is improved.

[0037] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
