Description

Technical Field

[0001] The present application relates to the field of new energy vehicle sockets, and in particular to replaceable discharge sockets. Background Art

[0002] With the development of new energy vehicles and the increasing demand for on-board electrical appliances, new energy vehicle suppliers usually install sockets inside the vehicle for on-board electrical appliances. The electronic components inside the existing socket module are directly connected to the power supply through the power harness. Since users frequently plug and unplug the plug module during use, it is easy to cause damage to the socket module.

[0003] Once the socket module fails, the maintenance personnel need to cut off the connection between the power harness and the socket module, peel off the rubber on the outside of the power harness, and connect it to the new socket module. Since the reserved length of the power harness is limited, this method will cause the reserved length of the power harness to become shorter and shorter. After several replacements, the reserved length of the power harness may be too short to replace the socket module. If you do not want to shorten the power harness, you can only completely disassemble the socket module for maintenance. This method takes a long time and has high maintenance costs. Therefore, it needs to be improved. Utility Model Content

[0004] In order to improve the convenience of replacing the discharge socket, the present application provides a replaceable discharge socket.

[0005] The replaceable discharge socket provided in this application adopts the following technical solution:

[0006] A replaceable discharge socket comprises a socket module and a power harness, wherein a connector module is arranged between the socket module and the power harness; the socket module comprises a socket shell, wherein a male terminal is arranged in the socket shell, and the connector module comprises a connector shell, wherein a female terminal is arranged in the connector shell, wherein the female terminal is crimped with the power harness, and wherein the male terminal can cooperate with the female terminal to form a passage; a double snap-on assembly is arranged between the socket shell and the connector shell, wherein the double snap-on assembly comprises a pressing piece, a paddle and a fixing block; the fixing block is mounted on the socket shell, the pressing piece is swingably mounted on the connector shell, and an end of the pressing piece close to the fixing block can be snap-on with the fixing block; the paddle is movably arranged between the pressing piece and the connector shell, and an end of the paddle close to the fixing block can press the pressing piece tightly against the fixing block.

[0007] By adopting the above technical solution, during installation, the operator installs the power cord on the connector module, connects the female terminal to the power supply, and then installs the paddle on the connector housing. The operator holds the socket housing and inserts it into the socket housing. After one end of the pressing piece is lifted and passes over the fixed block, the pressing piece swings back to press the pressing piece against the socket housing and is clamped with the fixed block. At this time, the socket housing and the connector housing are initially locked, and the male terminal is connected with the female terminal. The operator pushes the paddle until one end of the paddle is lifted and passes over the fixed block and the pressing piece in turn. The paddle rebounds under the action of elasticity, and the paddle presses the pressing piece against the socket housing and the fixed block, realizing the double locking of the connector housing and the socket housing. When replacement is required, the operator presses the pressing piece to lift one end of it, and the pressing piece drives the paddle to lift. When the pressing piece and the paddle are both higher than the fixed block, the socket housing is controlled to move away from the connector housing, the pressing piece and the paddle pass over the fixed block, and the socket housing and the connector housing are unlocked. Then release the pressing piece, let it swing back to its original state, and pull the paddle back to disengage it. The operator takes a new socket module and repeats the above steps to install it. The socket module is easy to replace and takes a short time to replace; and the replacement can be completed without cutting off the power harness.

[0008] Optionally, the pressing piece includes two cantilevers, two arc rods, a connecting block and a step block, the two arc rods are respectively installed in the middle part of the two cantilevers, the end of the arc rod away from the cantilever is connected to the connector housing, and both ends of the cantilever in the length direction are suspended; the connecting block is arranged at the end of the cantilever away from the connector housing, the connecting blocks are respectively connected to the two cantilevers, there is a gap between the two cantilevers, the side wall of the connecting block close to the connector housing can be abutted against the side wall of the fixing block away from the connector housing; the step block is arranged at the end of the cantilever away from the connecting block, the step blocks are respectively connected to the two cantilevers; the paddle is movably arranged between the cantilever and the connector housing.

[0009] Optionally, the fixing block is tilted close to the side wall of the connector housing, and the side wall of the fixing block tilts downward toward the connector housing; the connecting block is tilted away from the side wall of the connector housing and cooperates with the tilted side wall of the fixing block.

[0010] By adopting the above technical solution, the operator controls the socket housing to approach the connector housing, the connecting block moves upward along the inclined side wall of the fixed block, the connecting block is lifted upward relative to the connector housing, and the connecting block drives the cantilever to rotate, squeezing the arc rod to bend. When the arc rod bends, its internal stress is evenly dispersed on the arc profile of the arc rod, reducing the possibility of fracture when the arc rod is bent, and increasing the service life of the arc rod. When the connecting block passes over the fixed block, the internal force of the arc rod causes the cantilever to rotate and the connecting block falls. Since the length direction of the cantilever in the free state has an angle with the horizontal plane, the cantilever presses the connecting block against the top wall of the socket housing and the side wall of the fixed block away from the connector housing. The connecting block is engaged with the fixed block, and the socket housing and the connector housing are initially locked.

[0011] Optionally, a step is provided on the top wall of the step block, and the step extends upward in a direction away from the socket housing.

[0012] By adopting the above technical solution, when it is necessary to release the clamping connection between the connecting block and the fixed block, the operator presses the step block with one hand, and the step block drives the cantilever to rotate, and the arc rod bends. When the connecting block is higher than the fixed block, the operator holds the socket shell with the other hand and controls it to move away from the connector shell to release the clamping connection between the connecting block and the fixed block. The operator then releases the step block, and the arc rod recovers and drives the cantilever to rotate. The setting of the step increases the friction between the step block and the operator's hand; when pressing, the operator applies force downward in a direction away from the socket shell, and the force direction is perpendicular to the direction of the step. The ergonomic design reduces the possibility of the operator losing his hand when pressing.

[0013] Optionally, the paddle includes a tooling plate, a hook and a baffle, the tooling plate is slidably arranged between the cantilever and the connector shell, the tooling plate can move back and forth along the length direction of the cantilever, the hook is installed in the middle part of the tooling plate, the end of the hook close to the socket shell can be inserted between the two cantilevers, and the end of the hook away from the connector shell can press the connecting block onto the fixed block; the hook is inclined away from the side wall of the connector shell, and the inclined side wall of the hook cooperates with the inclined side wall of the fixed block; a clearance groove is opened on the top wall of the hook, and the end of the cantilever close to the step block can be pressed into the clearance groove; the baffle is installed on the side of the tooling plate away from the hook, and the side wall of the baffle close to the hook can be against the side wall of the step block away from the socket shell.

[0014] By adopting the above technical solution, when the connecting block is engaged with the fixed block, the operator moves the baffle plate toward the fixed block, and the baffle plate drives the tooling plate and the hook to move toward the fixed block. The hook undergoes elastic deformation and lifts upward along the inclined surface of the fixed block. When the hook passes over the fixed block, the hook rebounds and exerts pressure on the connecting block, pressing the connecting block against the outside of the socket and the fixed block. The socket housing and the connector housing are double locked, and it is difficult for them to disengage by themselves under the vibration of the vehicle. When it is necessary to release the double locking, the operator presses the step block to make the step block enter the clearance groove, and the step block drives the cantilever to rotate, so that the connecting block is lifted and the hook on it is lifted. When the connecting block is higher than the fixed block, the operator separates the socket housing from the connector housing, and the double locking is released. After the operator releases the step block, he immediately moves the baffle plate to move the baffle plate away from the socket housing. The step block, cantilever and connecting block rotate back to the original state, at which time the top wall of the connecting block is lower than the bottom wall of the buckle near the fixed block, the baffle drives the tooling plate and the hook to move away from the socket housing, and the hook is separated from the connecting block and returned between the two cantilevers. The connection between the hook and the connecting block is released.

[0015] Optionally, two connecting rods are installed on the tooling plate, and the two connecting rods are respectively located on both sides of the width direction of the hook, and the length direction of the connecting rod is parallel to the length direction of the hook; two relative sliding grooves are installed on the top wall of the connector shell, and the two connecting rods are respectively inserted in the two sliding grooves, and semicircular protrusions are installed on the side walls of the two connecting rods that are away from each other, and the side walls of the protrusions can be abutted against the inner walls of the sliding grooves; an elastic groove is penetrated through the top wall of the connecting rod, and the protrusion is located in the middle of the length direction of the elastic groove.

[0016] By adopting the above technical solution, when the two connecting rods are respectively inserted into the two sliding groove bodies, the protrusions on both sides of the tooling plate are respectively pressed against the inner side walls of the sliding groove body, and at this time, the part of the connecting rod connected by the protrusion located at the elastic groove is slightly deformed, so that the contact between the protrusion and the inner wall of the sliding groove body is elastic contact, reducing the friction between the protrusion and the inner wall of the sliding groove body, and reducing the wear of the protrusion. The setting of the protrusion provides resistance to the movement of the tooling plate, reducing the possibility of the tooling plate moving on its own under the vibration of the vehicle.

[0017] Optionally, a sliding bar is installed on the bottom wall of the tooling plate close to the connector shell, and the sliding bar is in contact with the top wall of the connector shell away from the bottom wall of the tooling plate; a sliding block is installed on the bottom wall of the hook, and the sliding block is in contact with the top wall of the connector shell away from the bottom wall of the hook.

[0018] By adopting the above technical solution, when the tooling plate moves along the length direction of the hook, only the sliding bar and the sliding block are in contact with the top wall of the connector housing, avoiding friction between the bottom wall of the tooling plate and the top wall of the connector housing, thereby reducing wear of the tooling plate.

[0019] Optionally, a rear end cover is provided at one end of the connector shell away from the socket shell, and the rear end cover is snap-connected with the connector shell. The rear end cover protrudes from the peripheral wall of the connector shell away from the bottom plate of the socket shell, and the side wall of the baffle away from the hook can be abutted against the bottom plate of the rear end cover.

[0020] By adopting the above technical solution, when installing the connector, the operator first passes the power harness through the rear cover, crimps the end of the power harness close to the socket module with the female terminal, and then puts the female terminal into the cavity in the connector housing. Then control the tooling plate close to the end of the sliding slot away from the socket housing, and insert the two connecting rods from the end of the sliding slot away from the socket housing into the sliding slot. At this time, the hook is also located between the two cantilevers. The operator inserts the end of the rear cover close to the socket housing into the connector housing until the rear cover is engaged with the connector housing. The rear cover fixes the female terminal in the connector housing, making it difficult for the female terminal to move. The rear cover also closes the end of the sliding slot away from the socket housing, making it difficult for the tooling plate to escape from it.

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0022] 1. During installation, the operator installs the power cord on the connector module, connects the female terminal to the power supply, and then installs the paddle on the connector housing. The operator holds the socket housing and inserts it into the socket housing. After one end of the pressing piece is lifted and passes over the fixed block, the pressing piece swings back to press the pressing piece against the socket housing and engages with the fixed block. At this time, the socket housing and the connector housing are initially locked, and the male terminal is connected to the female terminal. The operator pushes the paddle until one end of the paddle is lifted and passes over the fixed block and the pressing piece in turn. The paddle rebounds under the action of elasticity, and the paddle presses the pressing piece against the socket housing and the fixed block, realizing the double locking of the connector housing and the socket housing. When replacement is required, the operator presses the pressing piece to lift one end of it, and the pressing piece drives the paddle to lift. When the pressing piece and the paddle are both higher than the fixed block, the socket housing is controlled to move away from the connector housing, the pressing piece and the paddle pass the fixed block, and the socket housing and the connector housing are unlocked. Then release the pressing piece, let it swing back to its original state, and pull the paddle back to detach it from the pressing piece. The operator takes a new socket module and repeats the above steps to install it. The socket module is easy to replace and takes a short time to replace; and the replacement can be completed without cutting off the power harness;

[0023] 2. When the connection between the connecting block and the fixed block needs to be released, the operator presses the step block with one hand, and the step block drives the cantilever to rotate, causing the arc rod to bend. When the connecting block is higher than the fixed block, the operator holds the socket housing with the other hand and controls it to move away from the connector housing to release the connection between the connecting block and the fixed block. The operator then releases the step block, and the arc rod returns to its original position, driving the cantilever to rotate. The setting of the step increases the friction between the step block and the operator's hand; when pressing, the operator applies force downward in a direction away from the socket housing, and the direction of force is perpendicular to the direction of the step. The ergonomic design reduces the possibility of the operator losing his hand when pressing;

[0024] 3. When the two connecting rods are respectively inserted into the two sliding groove bodies, the bumps on both sides of the tooling plate are respectively pressed against the inner wall of the sliding groove body. At this time, the part of the connecting rod connected by the bump located at the elastic groove is slightly deformed, so that the contact between the bump and the inner wall of the sliding groove body is elastic, reducing the friction between the bump and the inner wall of the sliding groove body and reducing the wear of the bump. The setting of the bump provides resistance to the movement of the tooling plate, reducing the possibility of the tooling plate moving on its own under the vibration of the vehicle.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-6 This application is described in further detail.

[0033] The present application embodiment discloses a replaceable discharge socket. Figure 1 and Figure 2 The replaceable discharge socket includes a socket module, which includes a socket housing 1, which is a cylindrical shape with two ends open. A male terminal 11 is arranged in the socket housing 1, and the male terminal 11 is connected to the electrical components in the socket housing 1. A connector module is arranged between the socket module and the power harness, and the connector module includes a connector housing 2, which is a cylindrical shape with two ends open. A female terminal 21 is arranged in the connector housing 2, and the female terminal 21 can cooperate with the male terminal 11 to form a passage, and the end of the female terminal 21 away from the male terminal 11 is crimped with the power harness.

[0034] Reference Figure 3 and Figure 4 A double snap assembly is provided between the socket housing 1 and the connector housing 2, and the double snap assembly includes a pressing piece 3, a paddle 4 and a fixing block 5. The fixing block 5 is mounted on the socket housing 1, and the pressing piece 3 is swingably mounted on the connector housing 2, and the end of the pressing piece 3 close to the fixing block 5 can be snapped with the fixing block 5. The paddle 4 is movably arranged between the pressing piece 3 and the connector housing 2, and the end of the paddle 4 close to the fixing block 5 can press the pressing piece 3 against the fixing block 5.

[0035] When installing the replaceable discharge socket, the operator first installs the reserved power harness on the connector module, so that the female terminal 21 is connected to the power supply. Then place the paddle 4 between the pressing piece 3 and the connector housing 2, and the paddle 4 is located at the end of the connector housing 2 away from the socket housing 1. The operator holds the socket housing 1 close to the connector housing 2, and inserts the end of the connector housing 2 away from the power harness into the socket housing 1. During this process, the end of the pressing piece 3 away from the connector housing 2 is lifted and passes over the fixing block 5. After passing the fixing block 5, the pressing piece 3 swings back to the original state, and the pressing piece 3 is pressed against the socket housing 1 and is engaged with the fixing block 5. At this time, the socket housing 1 and the connector housing 2 are initially locked, and the male terminal 11 is connected to the female terminal 21. The operator pushes the paddle 4 in the direction close to the socket housing 1 until the end of the paddle 4 close to the socket housing 1 is lifted up and passes over the fixing block 5 and the end of the pressing piece 3 away from the connector housing 2 in turn. After passing over the pressing piece 3, the paddle 4 rebounds to its original state under the action of elasticity, and the paddle 4 presses the pressing piece 3 tightly against the socket housing 1 and the fixing block 5, realizing double locking of the connector housing 2 and the socket housing 1, and the installation of the discharge socket is completed.

[0036] When the socket module needs to be replaced, the operator presses the end of the pressing piece 3 away from the socket shell 1 to lift the end of the pressing piece 3 close to the socket shell 1, and the pressing piece 3 drives the paddle 4 to lift the end close to the socket shell 1. At this time, the ends of the pressing piece 3 and the paddle 4 close to the fixed block 5 are higher than the fixed block 5. The operator keeps pressing to move the socket shell 1 away from the connector shell 2 until the ends of the pressing piece 3 and the paddle 4 close to the fixed block 5 pass over the fixed block 5, and the socket shell 1 and the connector shell 2 are unlocked. Then release the pressing piece 3, and the pressing piece 3 swings back to the original state. The operator pulls the paddle 4 away from the socket shell 1 to make the paddle 4 detach from the pressing piece 3 and return to the end of the connector shell 2 away from the socket shell 1. The operator takes a new socket module and repeats the above steps to install it.

[0037] Reference Figure 4 and Figure 5 The pressing piece 3 includes two cantilevers 31. The length direction of the cantilevers 31 is arranged along the length direction of the connector housing 2, and the two cantilevers 31 are arranged at intervals in the width direction. An arc rod 32 is respectively installed on the side walls of the two cantilevers 31 that are away from each other. The arc rod 32 is installed in the middle of the cantilever 31. The end of the arc rod 32 away from the cantilever 31 is connected to the connector housing 2, and the arc profile of the arc rod 32 is tilted downward in the direction away from the socket housing 1. Both ends of the cantilever 31 in the length direction are suspended relative to the top wall of the connector housing 2. Under the action of external force, the cantilever 31 can swing around the connection point between it and the arc rod 32. The connector housing 2, the arc rod 32 and the cantilever 31 are integrally formed, and the materials are all plastic. There is an angle between the length direction of the cantilever 31 and the horizontal plane, and the cantilever 31 is tilted downward in the direction close to the socket housing 1.

[0038] A connecting block 33 is provided at one end of the cantilever 31 away from the connector housing 2. The connecting block 33 is installed between the two cantilevers 31, and the connecting block 33 is integrally formed with the two cantilevers 31. The side wall of the connecting block 33 close to the connector housing 2 can be abutted against the side wall of the fixing block 5 away from the connector housing 2, and the bottom wall of the connecting block 33 can be abutted against the top wall of the socket housing 1. The fixing block 5 is inclined near the side wall of the connector housing 2, and the side wall of the fixing block 5 is inclined downward toward the direction close to the connector housing 2. The connecting block 33 is inclined away from the side wall of the connector housing 2 and cooperates with the inclined side wall of the fixing block 5.

[0039] The operator controls the socket housing 1 to approach the connector housing 2. When the protruding portion of the connector housing 2 is inserted into the socket housing 1, the inclined side wall of the connecting block 33 contacts the inclined side wall of the fixing block 5. The operator continues to move the socket housing 1 and the connector housing 2 closer, and the connecting block 33 moves upward along the inclined side wall of the fixing block 5. The connecting block 33 is lifted upward relative to the connector housing 2. The connecting block 33 drives the end of the cantilever 31 close to the connecting block 33 to be lifted away from the socket housing 1, and the cantilever 31 rotates with the connection point between it and the arc rod 32 as the center of the circle. When the cantilever 31 rotates, the connection point between the arc rod 32 and the cantilever 31 moves toward the direction close to the connector housing 2, squeezing the arc rod 32 to make the arc rod 32 bend. When the arc rod 32 bends, its internal stress is evenly dispersed on the arc profile of the arc rod 32, reducing the possibility of fracture when the arc rod 32 is bent, and increasing the service life of the arc rod 32. Until the connection block 33 passes over the fixed block 5, the internal force tending to restore inside the arc rod 32 causes the cantilever 31 to swing and rotate, and the end of the cantilever 31 close to the connection block 33 falls toward the direction close to the socket housing 1, and the cantilever 31 drives the connection block 33 to fall. Since the length direction of the cantilever 31 in the free state is at an angle with the horizontal plane, the cantilever 31 makes the connection block 33 press against the top wall of the socket housing 1, and the connection block 33 also presses against the side wall of the fixed block 5 away from the connector housing 2.

[0040] Reference Figure 4 and Figure 5 A step block 34 is provided at one end of the cantilever 31 away from the connecting block 33, and the step block 34 is integrally formed with the two cantilever arms 31. A step is provided on the top wall of the step block 34, and the step is upwardly arranged away from the socket housing 1. The paddle 4 is movably arranged between the cantilever 31 and the connector housing 2, and a groove is provided on the bottom wall of the step block 34, and the groove on the bottom wall of the step block 34 is connected to the gap between the two cantilever arms 31 to allow the paddle 4 to move.

[0041] When it is necessary to release the connection between the connection block 33 and the fixed block 5, the operator presses the step block 34 with one hand to make the step block 34 close to the top wall of the connector housing 2. The step block 34 drives the end of the cantilever 31 close to the step block 34 to fall in the direction close to the socket housing 1. The cantilever 31 rotates with the connection point between it and the arc rod 32 as the center of the circle, and the arc rod 32 bends. The end of the cantilever 31 close to the connection block 33 drives the connection block 33 to lift up until the bottom wall of the connection block 33 is higher than the top wall of the fixed block 5. The operator holds the socket housing 1 with the other hand and controls it to move away from the connector housing 2, so that the connection block 33 passes over the top of the fixed block 5, and the connection between the connection block 33 and the fixed block 5 is released. When the socket housing 1 is completely separated from the connector housing 2, the operator releases the step block 34, and the arc rod 32 recovers and drives the cantilever 31 to rotate. After the cantilever 31 and the connection block 33 return to the initial state, the operator pulls back the paddle 4 for the next use. The setting of the step block 34 increases the friction with the operator's hand; when pressing, the operator applies force downward in a direction away from the socket housing 1, and the direction of force is perpendicular to the direction of the step. The ergonomic design reduces the possibility of the operator losing his hand when pressing.

[0042] Reference Figure 4 and Figure 6 The paddle 4 includes a tooling plate 41, which is slidably arranged between the cantilever 31 and the top wall of the connector housing 2. Two connecting rods 45 are arranged on the tooling plate 41, and the two connecting rods 45 are integrally formed on the two side walls in the width direction of the tooling plate 41. Two sliding grooves 22 with openings facing each other are installed on the top wall of the connector housing 2, and the sliding grooves 22 are integrally formed on the connector housing 2, and the length direction of the sliding grooves 22 is parallel to the length direction of the cantilever 31. The two connecting rods 45 are respectively inserted into the two sliding grooves 22; semicircular protrusions 46 are installed on the side walls of the two connecting rods 45 that are away from each other, and the protrusions 46 are integrally formed with the connecting rods 45, and the side walls of the protrusions 46 can be against the inner wall of the sliding grooves 22. An elastic groove 47 is opened on the top wall of the connecting rod 45, and the elastic groove 47 passes through the bottom wall of the connecting rod 45. The length direction of the elastic groove 47 is parallel to the length direction of the connecting rod 45 , and the protrusion 46 is located in the middle of the length direction of the elastic groove 47 .

[0043] When the two connecting rods 45 are respectively inserted into the two sliding grooves 22, the protrusions 46 on both sides of the tooling plate 41 are respectively pressed against the inner side walls of the sliding grooves 22. At this time, the part of the connecting rod 45 connected by the protrusions 46 located at the elastic groove 47 is slightly deformed, so that the contact between the protrusions 46 and the inner wall of the sliding groove 22 is elastic, reducing the friction between the protrusions 46 and the inner wall of the sliding groove 22, and reducing the wear of the protrusions 46. The setting of the protrusions 46 provides resistance to the movement of the tooling plate 41, reducing the possibility of the tooling plate 41 moving on its own under the vibration of the vehicle.

[0044] Reference Figure 4 and Figure 5 A hook 42 is provided between the two connecting rods 45, and the end of the hook 42 close to the tooling plate 41 is integrally formed with the middle part of the tooling plate 41 in the width direction. The end of the hook 42 close to the socket housing 1 can be inserted between the two cantilevers 31, and the side wall of the hook 42 is slidably matched with the inner side wall of the cantilever 31, so that the tooling plate 41 can reciprocate along the length direction of the cantilever 31. The end of the hook 42 away from the connector housing 2 can press the connecting block 33 onto the fixing block 5. The hook 42 is inclined away from the side wall of the connector housing 2, and the inclined side wall of the hook 42 can match the inclined side wall of the fixing block 5. A clearance groove 44 is provided on the top wall of the hook 42, and the step block 34 can be pressed into the clearance groove 44. A baffle 43 is installed on the side wall of the tooling plate 41 away from the hook 42, and the side wall of the baffle 43 close to the hook 42 can be against the side wall of the step block 34 away from the socket housing 1.

[0045] After the connection block 33 is engaged with the fixed block 5, the tooling plate 41 is located at the side of the connector housing 2 away from the socket housing 1, and the connecting rod 45 is inserted in the sliding groove 22. The operator moves the baffle 43 to move the baffle 43 toward the fixed block 5, and the movement of the baffle 43 drives the tooling plate 41 and the hook 42 to move toward the fixed block 5. Until the side wall of the hook 42 away from the tooling plate 41 contacts the inclined side wall of the fixed block 5, the operator continues to apply thrust to the baffle 43, the hook 42 is elastically deformed, and the end of the hook 42 away from the tooling plate 41 is lifted upward along the inclined surface of the fixed block 5. After the end of the hook 42 away from the tooling plate 41 passes over the fixed block 5, the hook 42 applies pressure to the connection block 33 under the action of the internal force tending to return to the original state, and the hook 42 presses the connection block 33 against the top wall of the socket housing 1 and the side wall of the fixed block 5 away from the tooling plate 41. Under the friction between the protrusion 46 and the inner wall of the sliding groove body 22, the side wall of the baffle 43 is pressed against the side wall of the step block 34, and the tooling plate 41 is difficult to move by itself. At this time, the clearance groove 44 is located directly below the step block 34. The socket housing 1 and the connector housing 2 are double locked and are difficult to be disengaged by themselves under the vibration of the vehicle.

[0046] When the double lock needs to be released, the operator presses the step block 34, so that the step block 34 enters the clearance groove 44, and the top wall of the pressing block is lower than the top wall of the baffle 43. At this time, the step block 34 drives the cantilever 31 to rotate, so that the connecting block 33 is lifted; the lifting of the connecting block 33 drives one end of the hook 42 thereon to lift. When the bottom wall of the connecting block 33 is higher than the top wall of the fixing block 5, the operator completely separates the socket housing 1 from the connector housing 2, and the double lock is released. At this time, the operator still keeps pressing the step block 34, and the finger pressing the step block 34 is also in contact with the baffle 43. After the operator releases the step block 34, he immediately moves the baffle 43 to move the baffle 43 away from the socket housing 1. After the operator releases the step block 34, the step block 34, the cantilever 31 and the connecting block 33 rotate back to the original state, at which time the top wall of the connecting block 33 is lower than the bottom wall of the buckle near the end of the fixing block 5, and the baffle 43 drives the tooling plate 41 and the hook 42 to move away from the socket housing 1, and the hook 42 is separated from the connecting block 33 and returned between the two cantilevers 31. The connection between the hook 42 and the connecting block 33 is released.

[0047] Reference Figure 6 , a sliding bar 48 is installed on the bottom wall of the tooling plate 41 close to the connector housing 2, and the sliding bar 48 is in contact with the top wall of the connector housing 2 away from the bottom wall of the tooling plate 41. In this embodiment, two sliding bars 48 are provided, and the two sliding bars 48 are symmetrically arranged in the width direction of the tooling plate 41. A sliding block 49 is installed on the bottom wall of the hook 42, and the sliding block 49 is in contact with the top wall of the connector housing 2 away from the bottom wall of the hook 42. The sliding block 49 is located on the extension line of the center line of the two sliding bars 48, and the sliding block 49 and the sliding bar 48 jointly support the weight of the tooling plate 41, so that the tooling plate 41 moves parallel to the plane where the top wall of the connector housing 2 is located. When the tooling plate 41 moves along the length direction of the hook 42, only the sliding bar 48 and the sliding block 49 are in contact with the top wall of the connector housing 2, avoiding friction between the bottom wall of the tooling plate 41 and the top wall of the connector housing 2, thereby reducing the wear of the tooling plate 41.

[0048] Reference Figure 2 and Figure 5 A rear end cover 6 is provided at one end of the connector housing 2 away from the socket housing 1, and two wing plates are integrally formed on the outer wall of the rear end cover 6, and a groove is provided on the wing plate. A protrusion is provided on the outer wall of the connector housing 2, and the protrusion can be inserted into the groove on the wing plate, and the rear end cover 6 is snap-fitted with the connector housing 2. The rear end cover 6 protrudes from the peripheral wall of the connector housing 2 away from the bottom plate of the socket housing 1, and the side wall of the baffle 43 away from the hook 42 can be abutted against the bottom plate of the rear end cover 6. In this embodiment, the rear end cover 6 is a cylindrical shape with two ends opened, and the power harness passes through the hole on the rear end cover 6 and is connected to the female terminal 21.

[0049] When installing the connector, the operator first passes the power harness through the rear cover 6, crimps the end of the power harness close to the socket module with the female terminal 21, and then puts the female terminal 21 into the cavity in the connector housing 2. Then control the tooling plate 41 to be close to the end of the sliding slot 22 away from the socket housing 1, and insert the two connecting rods 45 from the end of the sliding slot 22 away from the socket housing 1 into the sliding slot 22. At this time, the hook 42 is also located between the two cantilevers 31. The operator inserts the end of the rear cover 6 close to the socket housing 1 into the connector housing 2 until the rear cover 6 is engaged with the connector housing 2. The rear cover 6 fixes the female terminal 21 in the connector housing 2, making it difficult for the female terminal 21 to move. The rear cover 6 also closes the end of the sliding slot 22 away from the socket housing 1, and the tooling plate 41 is difficult to escape from it.

[0050] When the connector module fails and needs to be replaced, the operator releases the clamping connection between the connector housing 2 and the rear end cover 6, removes the female terminal 21 from the connector housing 2, and then releases the crimping connection between the female terminal 21 and the power harness to replace the faulty part.

[0051] The implementation principle of the replaceable discharge socket of the embodiment of the present application is as follows: the operator first inserts the connecting rod 45 into the sliding groove body 22, and then snaps the rear end cover 6 with the connector housing 2, and the connector module is installed. The socket housing 1 is controlled to be close to the connector housing 2, and the connecting block 33 is lifted upward along the inclined surface of the fixed block 5, and the arc rod 32 is squeezed; when the connecting block 33 passes over the fixed block 5, the cantilever 31 swings to make the connecting block 33 snap with the fixed block 5, and the preliminary connection is completed. Then the operator toggles the baffle 43 to make the hook 42 lift upward along the inclined surface of the fixed block 5. After the hook 42 passes over the fixed block 5 and the connecting block 33, the hook 42 is restored to press the connecting block 33 against the socket housing 1 and the fixed block 5, and double locking is achieved. When it is necessary to release the lock, the operator presses the step block 34 to make the connecting block 33 drive the hook 42 to lift, and when the connecting block 33 is higher than the fixed block 5, the socket housing 1 is separated from the connector housing 2. The operator loosens the step block 34 and moves the baffle 43 to separate the hook 42 from the connection block 33, releasing the double lock. Take a new socket module and repeat the above steps to install it. The socket module is easy to replace and the replacement time is short; and the replacement can be completed without cutting off the power harness.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
