Description

Technical Field

[0001] The present invention relates to the technical field of connector terminals, and in particular to a novel fixing device for charging connector terminals. Background Art

[0002] Wire connector terminals are key components in electrical connection systems, which are used to ensure reliable electrical contact between wires, between wires and devices, or between wires and circuit boards. Terminals are usually made of metal, designed into specific shapes and sizes to suit different application requirements, and often with insulating materials to prevent short circuits and other safety hazards. Here is some important information about wire connector terminals: The main functions of wire connector terminals include, electrical connection: providing a stable and low-resistance current transmission path to ensure that power or signals can be efficiently transmitted from one point to another. Mechanical fixation: The wire is firmly fixed to the terminal through physical means (such as crimping, welding, screw tightening, etc.) to prevent loosening or falling off. Protection: Some terminals are designed with protective structures to protect the internal electrical connections from external environmental factors, such as dust, moisture, chemicals, etc.

[0003] The existing fixing device of the charging connector terminal can only fix the terminal to the interface through a single mechanical mechanism to ensure the stability of the connection. However, when disconnection is required in an emergency, the connection terminal cannot be disconnected from the interface in time, and it is impossible to respond in time in an emergency. For example, Chinese patent application CN201811033372.9 discloses a connection device for connecting wire and cable joints, which is provided with a first outer nest, a second outer nest and a connection shell, and can connect two sections of wire and cable, and fix them through a first tight hoop and a second tight hoop, so that the connection between the two sections of wire and cable is more convenient and firm. Although the technical solution of this application can fix the connection terminal to the interface, it still cannot disconnect the connection terminal from the interface in time in an emergency.

[0004] Therefore, a new type of fixing device for charging connector terminals is needed to solve the above problems. Summary of the invention

[0005] In order to solve the above problem, that is, to solve the problem that the existing fixing device cannot disconnect the connecting terminal from the interface in time, the present invention provides a novel fixing device for the charging connector terminal.

[0006] A novel fixing device for charging connector terminals comprises a wiring terminal and an interface, wherein the wiring terminal and the interface are provided with fixing mechanisms, wherein the fixing mechanism comprises a moving part fixedly sleeved on the wiring terminal, a fixing part sleeved on the interface, four connecting rods are provided between the moving part and the fixing part, the connecting rods are slidably connected to the moving part, and the plug on the wiring terminal corresponds to the jack on the interface.

[0007] Specifically, when in use, the movable part is fixedly mounted on the wiring terminal, and then the plug on the wiring terminal is matched with the socket on the interface, and at the same time, the fixed part is mounted on the interface, and the fixed part and the interface are fixed, and then the movable part is slid to slide on the connecting rod, so that the movable part moves toward the fixed part, and at the same time, the movable part drives the wiring terminal to move toward the interface, so that the plug on the wiring terminal is inserted into the socket on the interface. After the connection between the wiring terminal and the interface is completed, the moving part is stopped.

[0008] By setting up the fixing mechanism, the movable part can be connected to the terminal, and the fixed part can be connected to the interface, and the movable part and the fixed part are connected by a connecting rod so that the terminal corresponds to the interface, thereby fixing the interface and the terminal, and by the sliding connection between the connecting rod and the movable part, the movable part can slide along the connecting rod so that the terminal is inserted into the interface, thereby the terminal can be connected and disconnected with the interface under the movement of the movable part.

[0009] Preferably, the movable part includes an installation frame fixedly sleeved on the wiring terminal, an air cavity is opened in the installation frame, and an air inlet pipe and an air outlet pipe are respectively connected at both ends of a side wall of the air cavity away from the fixed part, a movable plate is slidably connected in the air cavity, four first springs are connected between the movable plate and a side wall of the air cavity away from the fixed part, four connecting holes are opened on a side wall of the air cavity close to the fixed part, four connecting rods correspond to the four connecting holes, the four connecting rods enter the air cavity through the connecting holes, and the connecting rods are fixedly connected to the movable plate.

[0010] Furthermore, a side wall of the air cavity close to the fixing piece is connected with an air hole, and the air hole is connected with the external space.

[0011] Specifically, in the initial state, when the first spring is in a natural state, the movable plate is located on a side of the air cavity close to the fixing piece, and when the wiring terminal needs to be inserted into the interface, the air cavity is evacuated through the air outlet pipe, and the air inlet pipe is closed at the same time. Under the action of external air pressure, the movable plate makes the installation frame move toward the direction close to the interface, and the installation frame drives the wiring terminal to move toward the direction close to the interface, and compresses the first spring at the same time, so that the wiring terminal is inserted into the interface; when the wiring terminal needs to be disconnected from the interface, the air cavity is inflated through the air inlet pipe, and the air outlet pipe is closed at the same time. Under the action of the air pressure in the air cavity and the action of the first spring, the installation frame moves in a direction away from the fixing piece, and the installation frame drives the wiring terminal to be pulled out of the interface, so that the wiring terminal is disconnected from the interface.

[0012] By setting the moving parts, the air cavity is evacuated and deflated to realize the movement of the installation frame, so that the wiring terminal is moved, so as to realize the docking and disconnection of the wiring terminal and the interface, so that in an emergency, the wiring terminal can be disconnected from the interface in time.

[0013] Preferably, the fixing member includes a fixing frame, which is sleeved on the interface, and the inner ring surface of the fixing frame is provided with a mounting groove opening toward the interface, an airbag is fixedly connected in the mounting groove, an air groove is provided in the connecting rod, one end of the air groove is connected to the air cavity, and the other end of the air groove is connected to the airbag, and an electromagnetic valve is provided in the air groove.

[0014] Specifically, during use, when the fixing part needs to be fixed to the interface, the solenoid valve is opened, and the air cavity is inflated through the air inlet pipe, and the air outlet pipe is closed at the same time, so that the gas in the air cavity enters the air groove through the solenoid valve, and then the gas enters the airbag through the air groove, causing the airbag to expand and clamp the interface. After the airbag is inflated, the solenoid valve is closed.

[0015] Through the setting of the fixing part, the air cavity is inflated to expand the airbag and clamp the interface, so that the fixing part and the interface are fixed, which is convenient for the subsequent movement of the moving part and the docking and disconnection of the wiring terminal and the interface. Moreover, through this setting, there is no need to improve the interface, which improves the adaptability of the device and facilitates the subsequent application of existing equipment.

[0016] Furthermore, the solenoid valve is a prior art and will not be described in detail.

[0017] Preferably, four retaining members are evenly arranged between the movable member and the fixed member, and the retaining member includes a retaining rod fixedly connected to the mounting frame, and an embedding groove opening downward is provided at one end of the retaining rod close to the fixed member, and a clamping block is slidably connected in the embedding groove, and a second spring is connected between the clamping block and the embedding groove, and a chamfer is provided at the lower end of a side surface of the clamping block close to the fixed member, and a clamping groove opening toward the movable member is provided in the fixed frame, and the clamping groove is connected to the mounting groove, and the retaining rod can be inserted into the clamping groove.

[0018] Furthermore, the clamping block can abut against a side wall of the clamping slot close to the moving part.

[0019] Specifically, during use, when the wiring terminal is inserted into the interface, the retaining rod is inserted into the slot, and during the process of inserting the retaining rod into the buckle, the chamfer of the card block first abuts against the opening of the card slot, and under the abutment action of the opening of the card slot, the card block compresses the second spring and enters the embedded slot. After the card block enters the card slot, the card block pops out of the embedded slot under the elastic force of the second spring, and the card block abuts against a side wall of the card slot close to the moving part; when the wiring terminal needs to be disconnected from the interface, the solenoid valve is opened, and the airbag continues to be inflated, so that the airbag continues to expand, and the airbag pushes the card block upward, and the card block compresses the second spring and enters the embedded slot, thereby releasing the limit on the retaining rod, so that the installation frame is reset under the action of the first spring, so that the wiring terminal is disconnected from the interface.

[0020] By setting the retaining piece, after the connecting terminal and the interface are docked, the connecting terminal and the interface are kept fixed by the retaining piece, thereby canceling the state in which the external air source device forms a negative pressure on the air cavity; and through the continued expansion of the airbag, the limit of the retaining rod by the block can be released, which facilitates the disconnection of the connecting terminal and the interface.

[0021] Preferably, the moving member further comprises a limiting ring fixedly connected to the inner wall of the air cavity, and the moving plate can abut against the limiting ring.

[0022] Specifically, during use, when the terminal is docked with the interface, the movable plate abuts against the limit ring; during use, low-temperature gas is transported into the air cavity through the air inlet pipe, the terminal is cooled through the air cavity, and the cooled gas is discharged through the air outlet pipe.

[0023] By setting the limiting ring, a certain cooling space can be formed in the air cavity after the wiring terminal is connected to the interface, so that low-temperature gas can enter the cooling space from the air inlet pipe to cool the wiring terminal.

[0024] Furthermore, one end of the interface away from the wiring terminal is fixedly connected to a connecting plate, and the connecting plate is fixedly connected to the electronic device.

[0025] Furthermore, a cable is connected to an end of the wiring terminal away from the interface, and a plug is provided at an end of the wiring terminal close to the interface.

[0026] Furthermore, the outer surface of the interface is made of rubber material.

[0027] By arranging that the outer surface of the interface is made of rubber material, the friction between the airbag and the interface is increased, so that the clamping of the airbag to the interface is more stable.

[0028] Furthermore, the air inlet pipe and the air outlet pipe are respectively connected to an air pump.

[0029] Furthermore, the air pump is a prior art and will not be described in detail.

[0030] The beneficial effects of the present invention are:

[0031] 1. Through the setting of the fixing mechanism, the movable part can be connected to the terminal, the fixed part can be connected to the interface, and the movable part and the fixed part are connected by a connecting rod so that the terminal corresponds to the interface, thereby fixing the interface and the terminal, and through the sliding connection between the connecting rod and the movable part, the movable part can slide along the connecting rod so that the terminal is inserted into the interface, so that the terminal can be connected and disconnected with the interface under the movement of the movable part.

[0032] 2. By setting the moving parts, the air cavity is evacuated and deflated to realize the movement of the installation frame, so that the terminal block is moved, so as to realize the docking and disconnection of the terminal block and the interface, so that in an emergency, the terminal block can be disconnected from the interface in time.

[0033] 3. Through the setting of the fixing part, the air cavity is inflated to expand the airbag and clamp the interface, so that the fixing part and the interface are fixed, which is convenient for the subsequent movement of the moving part and the docking and disconnection of the terminal and the interface. Moreover, through this setting, there is no need to improve the interface, which improves the adaptability of the device and facilitates the subsequent application of existing equipment.

[0034] 4. By setting the retaining piece, after the terminal and the interface are docked, the retaining piece can keep the connection between the terminal and the interface fixed, thereby canceling the state in which the external air source device forms a negative pressure on the air cavity; and through the continued expansion of the airbag, the limit of the retaining rod by the block can be released, which facilitates the disconnection of the terminal and the interface.

[0035] 5. By setting the limiting ring, after the wiring terminal is connected to the interface, a certain cooling space can be formed in the air cavity, which facilitates the low-temperature gas to enter the cooling space from the air inlet pipe to cool the wiring terminal.

It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0050] like Figure 1 , 2 As shown in Figure 3, an embodiment of the present invention discloses a novel fixing device for a charging connector terminal, including a wiring terminal 1 and an interface 2, wherein the wiring terminal 1 and the interface 2 are provided with a fixing mechanism 3, wherein the fixing mechanism 3 includes a moving part 31 fixedly sleeved on the wiring terminal 1, and a fixing part 32 is sleeved on the interface 2, and four connecting rods 33 are provided between the moving part 31 and the fixing part 32, and the connecting rods 33 are slidably connected to the moving part 31, and the plug on the wiring terminal 1 corresponds to the jack on the interface 2.

[0051] Specifically, when in use, the movable member 31 is fixedly mounted on the terminal block 1, and then the plug on the terminal block 1 is matched with the socket on the interface 2, and at the same time, the fixed member 32 is mounted on the interface 2, and the fixed member 32 is fixed to the interface 2, and then the movable member 31 is slid so that the movable member 31 slides on the connecting rod 33, so that the movable member 31 moves toward the fixed member 32, and at the same time, the movable member 31 drives the terminal block 1 to move toward the interface 2, so that the plug on the terminal block 1 is inserted into the socket on the interface 2. After the connection between the terminal block 1 and the interface 2 is completed, the moving member 31 is stopped.

[0052] By setting the fixing mechanism 3, the movable part 31 can be connected to the terminal 1, and the fixed part 32 can be connected to the interface 2, and the movable part 31 and the fixed part 32 are connected by the connecting rod 33, so that the terminal 1 corresponds to the interface 2, thereby fixing the interface 2 and the terminal 1, and by the sliding connection between the connecting rod 33 and the movable part 31, the movable part 31 can slide along the connecting rod 33, so that the terminal 1 is inserted into the interface 2, so that the terminal 1 can be connected and disconnected with the interface 2 under the movement of the movable part 31.

[0053] like Figure 4 , 5As shown in Figures 6 and 7, the movable member 31 includes a mounting frame 311 fixedly sleeved on the wiring terminal 1, an air cavity 312 is opened in the mounting frame 311, an air inlet pipe 313 and an air outlet pipe 314 are respectively connected at two ends of a side wall of the air cavity 312 away from the fixed member 32, a movable plate 315 is slidably connected in the air cavity 312, four first springs 316 are connected between the movable plate 315 and a side wall of the air cavity 312 away from the fixed member 32, four connecting holes 317 are opened in a side wall of the air cavity 312 close to the fixed member 32, four connecting rods 33 correspond to the four connecting holes 317, the four connecting rods 33 enter the air cavity 312 through the connecting holes 317, and the connecting rods 33 are fixedly connected to the movable plate 315.

[0054] Furthermore, a side wall of the air cavity 312 close to the fixing member 32 is connected with an air hole, and the air hole is connected with the external space.

[0055] Specifically, in the initial state, when the first spring 316 is in a natural state, the movable plate 315 is located on the side of the air cavity 312 close to the fixing piece 32. When the terminal 1 needs to be inserted into the interface 2, the air cavity 312 is evacuated through the air outlet pipe 314, and the air inlet pipe 313 is closed at the same time. Under the action of external air pressure, the movable plate 315 makes the installation frame 311 move toward the direction close to the interface 2, and the installation frame 311 drives the terminal 1 to move toward the direction close to the interface 2, and compresses the first spring 316 at the same time, so that the terminal 1 is inserted into the interface 2; when the terminal 1 needs to be disconnected from the interface 2, the air cavity 312 is inflated through the air inlet pipe 314, and the air outlet pipe 313 is closed at the same time. Under the action of the air pressure in the air cavity 312 and the action of the first spring 316, the installation frame 311 moves in the direction away from the fixing piece 32, and the installation frame 311 drives the terminal 1 to be pulled out from the interface 2, so that the terminal 1 is disconnected from the interface 2.

[0056] By setting the movable member 31, the air cavity 312 is evacuated and deflated to realize the movement of the installation frame 311, so that the terminal block 1 is moved, thereby realizing the docking and disconnection of the terminal block 1 and the interface 2, so that in an emergency, the terminal block 1 can be disconnected from the interface 2 in time.

[0057] like Figure 5 , 7As shown in FIG. 10 , the fixing member 32 includes a fixing frame 321, and the fixing frame 321 is sleeved on the interface 2. The inner ring surface of the fixing frame 321 is provided with a mounting groove 322 opening toward the interface 2. An air bag 323 is fixedly connected in the mounting groove 322. An air groove 324 is provided in the connecting rod 33. One end of the air groove 324 is communicated with the air cavity 312, and the other end of the air groove 324 is communicated with the air bag 323. A solenoid valve 325 is provided in the air groove 324.

[0058] Specifically, during use, when the fixing part 32 needs to be fixed to the interface 2, the solenoid valve 325 is opened, and the air cavity 312 is inflated through the air inlet pipe 313, and the air outlet pipe 314 is closed at the same time, so that the gas in the air cavity 312 enters the air groove 324 through the solenoid valve 325, and then the gas enters the airbag 323 through the air groove 324, so that the airbag 323 expands and clamps the interface 2. After the airbag 323 expands, the solenoid valve 325 is closed.

[0059] By setting the fixing part 32, the air cavity 312 is inflated to expand the airbag 323 and clamp the interface 2, so that the fixing part 32 is fixed to the interface 2, which is convenient for the subsequent movement of the moving part 31, and the connection terminal 1 and the interface 2 are connected and disconnected. Moreover, through this setting, there is no need to improve the interface 2, so that the adaptability of the device is improved, which is convenient for the subsequent application of existing equipment.

[0060] Furthermore, the solenoid valve 325 is a prior art and will not be described in detail.

[0061] like Figure 1 , 2 As shown in Figures 6 and 8, four retaining members 34 are evenly arranged between the movable member 31 and the fixed member 32, and the retaining member 34 includes a retaining rod 341 fixedly connected to the mounting frame 311, and an embedding groove 342 with an opening downward is formed on one end of the retaining rod 341 close to the fixed member 32, and a clamping block 343 is slidably connected in the embedding groove 342, and a second spring 344 is connected between the clamping block 343 and the embedding groove 342, and a chamfer is formed on the lower end of a side surface of the clamping block 343 close to the fixed member 32, and a clamping groove 345 with an opening toward the movable member 31 is formed in the fixed frame 321, and the clamping groove 345 is communicated with the mounting groove 322, and the retaining rod 341 can be inserted into the clamping groove 345.

[0062] Furthermore, the block 343 can abut against a side wall of the slot 345 close to the moving member 31 .

[0063] Specifically, when in use, when the wiring terminal 1 is inserted into the interface 2, the retaining rod 341 is inserted into the card slot 345, and in the process of the retaining rod 341 being inserted into the buckle 345, the chamfer of the card block 343 first abuts against the opening of the card slot 345, and under the abutment effect of the opening of the card slot 345, the card block 343 compresses the second spring 344 and enters the embedding groove 342. When the card block 343 enters the card slot 345, the card block 343 is pulled out of the embedding groove 342 under the elastic force of the second spring 344. The block 343 pops up and abuts against a side wall of the slot 345 close to the movable part 31; when the terminal 1 needs to be disconnected from the interface 2, the solenoid valve 325 is opened and the airbag 323 is continuously inflated, so that the airbag 323 continues to expand, and the airbag 323 pushes the block 343 upward, and the block 343 compresses the second spring 344 to enter the embedding groove 342, releasing the limit on the retaining rod 341, so that the mounting frame 311 is reset under the action of the first spring 316, so that the terminal 1 is disconnected from the interface 2.

[0064] By setting the retaining member 34, after the connecting terminal 1 and the interface 2 are docked, the connecting terminal 1 and the interface 2 are kept fixed by the retaining member 34, thereby eliminating the state in which the external air source device forms a negative pressure on the air cavity 312; and through the continued expansion of the air bag 323, the limit of the retaining rod 341 by the block 343 can be released, thereby facilitating the disconnection of the connecting terminal 1 and the interface 2.

[0065] like Figure 5 , 6 As shown in , 7 , the moving member 31 also includes a limiting ring 318 fixedly connected to the inner wall of the air cavity 312 , and the moving plate 315 can abut against the limiting ring 318 .

[0066] Specifically, during use, when the terminal 1 is docked with the interface 2, the movable plate 315 abuts against the limit ring 318; during use, low-temperature gas is transported into the air cavity 312 through the air inlet pipe 313, the terminal 1 is cooled through the air cavity 312, and the cooled gas is discharged through the air outlet pipe 314.

[0067] By setting the limiting ring 318 , after the connecting terminal 1 is connected to the interface 2 , a certain cooling space can be formed in the air cavity 312 , so that low-temperature gas can enter the cooling space from the air inlet pipe 313 to cool the connecting terminal 1 .

[0068] Furthermore, one end of the interface 2 away from the wiring terminal 1 is fixedly connected to a connecting plate, and the connecting plate is fixedly connected to the electronic device.

[0069] Furthermore, a cable is connected to one end of the wiring terminal 1 away from the interface 2 , and a plug is provided at one end of the wiring terminal 1 close to the interface 2 .

[0070] Furthermore, the outer surface of the interface 2 is made of rubber material.

[0071] By making the outer surface of the interface 2 made of rubber material, the friction between the airbag 323 and the interface 2 is increased, so that the clamping of the airbag 323 to the interface 2 is more stable.

[0072] Furthermore, the air inlet pipe 313 and the air outlet pipe 314 are respectively connected to an air pump.

[0073] Furthermore, the air pump is a prior art and will not be described in detail.
