[0033] Example 1

[0034] Reference Figure 1 , this embodiment provides a relay with a protection mechanism.

[0035] The relay with a protective mechanism includes an operating component 100, including a relay 101 and a processing tank 102 set in the relay 101. The opening of the processing tank 102 facilitates the installation of the adjustment member 103. The adjustment member 103 is slidably installed inside the processing tank 102. Through the setting of the adjustment member 103, the position of the cover plate 207 can be adjusted according to actual use conditions, so that the circuit is better inserted into the relay 101. The adjustment member 103 passes through the relay 101 and cooperates with the limit member 104. Through the setting of the limit member 104, After the adjusting member 103 is adjusted, the adjusting member 103 can be limited and fixed, so that the staff can better insert the wire into the relay 101 without the adjusting member 103 shaking back and forth. An auxiliary member 105 is arranged at one end of the adjusting member 103. Through the setting of the auxiliary member 105, when the adjusting member 103 is pulled outward, the auxiliary member 105 is driven to move synchronously, so that the fixing assembly 200 is opened to all sides, and the cover plate 207 is also lifted from the relay 101, so that the wire is better inserted into the relay 101;

[0036] The fixing assembly 200 includes a clamping piece 201. Through the setting of the clamping piece 201, after the wire is inserted into the relay 101, the wire can be clamped and fixed to ensure that the wire is in contact with the contact terminal, thereby ensuring that the wire is energized. The clamping piece 201 cooperates with the clamping member 204, and one side of the clamping member 204 cooperates with the contact terminal 205. Through the setting of the clamping member 204, after the clamping piece 201 clamps and fixes the wire, the wire can be wrapped and clamped from both sides, so that the wire is clamped more firmly and with the clamping piece The sheet 201 and the contact terminal 205 form an accommodating space to protect the wire end from which the insulation layer has been removed, thereby preventing a circuit short circuit or malfunction caused by water ingress inside the relay 101, thereby ensuring the normal operation of the relay. The outer wall of the contact terminal 205 is provided with a mounting frame 205a. The setting of the mounting frame 205a ensures that the contact terminal 205 can be fixed inside the processing tank 102, so that the wire can be smoothly contacted with the contact terminal 205 after being inserted into the relay 101, thereby ensuring the power supply of the wire. In this case, both ends of the auxiliary member 105 are provided with lifting members 206. By providing the lifting members 206, when the adjusting member 103 drives the auxiliary member 105 to move to the outside of the processing tank 102, the gas inside the lifting member 206 is squeezed, so that the right-angle rod 206f at the top of the lifting member 206 moves upward, thereby driving the cover plate 207 to move upward, so that the cover plate 207 is ejected from the processing tank 102, which is convenient for the staff to insert the wire into the relay 101. The top of the lifting member 206 is provided with a cover plate 207, and one side of the cover plate 207 is provided with a cover plate 207. A placement hole 207a is opened through the side, and the opening of the placement hole 207a facilitates the better insertion of the wire into the relay 101, and the wire is initially limited to avoid the electrical connection being too far away from the contact terminal 205 when inserted into the relay 101, thereby ensuring the power-on effect of the wire. A placement groove 102a matched with the cover plate 207 is opened on the processing groove 102. Through the setting of the placement groove 102a, the movement of the cover plate 207 is effectively limited to avoid the cover plate 207 from being offset during the movement.

[0037] When in use, first pull the adjusting member 103 to drive the auxiliary member 105 to move in the same direction. Under the action of the auxiliary member 105, the pressing plate 201 is pushed to move to one side of the adjusting member 103. The clamping member 204 is also moved to both sides in the processing tank 102 under the action of the auxiliary member 105. At the same time, the lifting member 206 lifts the right-angle rod 206f under the squeezing of the auxiliary member 105. Under the push of the right-angle rod 106f, the cover plate 207 on the top of the right-angle rod 206f moves upward, so that the cover plate 207 is lifted from the processing tank 102 to facilitate the insertion of the wires. After the wires are successfully inserted into the relay 101, the above actions are performed in reverse, so that the wires inserted into the relay 101 can be clamped and fixed, ensuring that the wires are energized while protecting the exposed wires, avoiding the phenomenon of circuit short circuit or failure due to water ingress inside the relay, thereby ensuring the normal operation of the relay.

[0038] Example 2

[0039] Reference Figure 2-4 , which is the second embodiment of the present invention, is based on the previous embodiment, and is different from the previous embodiment in that:

[0040] The adjusting member 103 includes a pull rod 103a slidably arranged inside the relay 101, and a first spring 103b is arranged at one end of the pull rod 103a. Through the setting of the first spring 103b, when a person releases the pull rod 103a, the pull rod 103a is pulled back into the relay 101 by the rebound force of the first spring 103b. The other end of the pull rod 103a is arc-shaped, and the other end surface of the pull rod 103a is provided with an anti-slip groove 103a-1. Through the setting of the anti-slip groove 103a-1, the staff can be more stable when pulling the pull rod 103a to avoid slipping.

[0041] Preferably, the limiting member 104 includes an adjusting groove 104a provided on the surface of the relay 101. The adjusting groove 104a allows the positioning block 104b to move up and down on the relay 101 according to actual usage. The adjusting groove 104a is provided with a positioning block 104b slidably disposed inside, and a pull ring 104c is provided on the outer wall of the positioning block 104b. The setting of the pull ring 104c allows the pull ring 104c to be pulled upward after the wire is inserted into the relay 101, and the positioning block 104b is moved synchronously under the drive of the pull ring 104c, so that the positioning block 104b is disengaged from the positioning groove 104d on the pull rod 103a, so that the pull rod 103a is no longer restricted and can smoothly rebound into the relay 101 under the action of the first spring 103b. The pull rod 103a is provided with a first positioning groove 104d and a second positioning groove 104d that cooperate with the positioning block 104b. Slot 104e, through the cooperation between the positioning block 104b and the first positioning slot 104d and the second positioning slot 104e, after the pull rod 103a is pulled out, the second positioning slot 104e on the pull rod 103a can contact the positioning block 104b, which is convenient for the positioning block 104b to be inserted into the pull rod 103a through the second positioning slot 104e, thereby locking the pull rod 103a and avoiding the pull rod 103a from stretching too long. At the same time, it is convenient to perform subsequent wire insertion actions after adjusting the pull rod 103a, and there is no need to control the pull rod 103a, which is more convenient to operate. After the pull rod 103a is retracted, the first positioning slot 104d on the pull rod 103a can contact the positioning block 104b, which is convenient for the positioning block 104b to be inserted into the pull rod 103a through the first positioning slot 104d, thereby locking the pull rod 103a and avoiding the pull rod 103a from moving after adjustment, thereby ensuring the clamping and protection effect of the wires.

[0042] When in use, first pull the pull ring 104c upwards, and the positioning block 104b moves synchronously under the drive of the pull ring 104c, so that the positioning block 104b is disengaged from the first positioning groove 104d on the pull rod 103a, so that the pull rod 103a is no longer restricted, and then pull the pull rod 103a outwards. When the pull rod 103a is pulled to the specified position, the positioning block 104b contacts the second positioning groove 104e on the pull rod 103a, thereby locking the pull rod 103a, making it convenient for the staff to insert the wire into the relay 101, and the pull rod 103a will not swing back and forth. When the wire is successfully inserted into the relay 101, repeat the above operation, disengage the positioning block 104b from the second positioning groove 104e, and insert it into the first positioning groove 104d on the pull rod 103a, thereby locking the pull rod 103a, avoiding the pull rod 103a from moving after adjustment, and ensuring the clamping and protection effect of the wire.

[0043] Example 3

[0044] Reference Figure 5-7 , which is the third embodiment of the present invention, is based on the previous embodiment, and is different from the previous embodiment in that:

[0045] A connecting frame 105a is provided at the top of one end of the pull rod 103a close to the first spring 103b. The connecting frame 105a is right-angled, and the end in contact with the clamping piece 204 is arc-shaped. Through the setting of the connecting frame 105a, it is convenient to push the clamping piece 201 and the clamping piece 204f to expand outward, so that the wires can be better inserted into the relay 101. The outer wall of the connecting frame 105a is symmetrically provided with connecting plates 105b, and an adjusting rod 105c is provided on one side of the connecting plate 105b. A piston 105d is provided at one end of the adjusting rod 105c. Through the cooperation between the connecting plate 105b, the adjusting rod 105c and the piston 105d, when the connecting frame 105a moves toward the pull rod 103a, the piston 105d can be driven to move in the same direction, so that the gas inside the lifting piece 206 is squeezed, so that the right-angle rod 206f on the lifting piece 206 moves upward, driving the cover plate 207 to move upward.

[0046] Preferably, the clamping member 204 includes an adjustment frame 204a arranged inside the processing tank 102, a slide bar 204c is slidably arranged on the adjustment frame 204a, and a slide rail 204b matching with the slide bar 204c is provided on the adjustment frame 204a. Through the cooperation between the slide rail 204b and the slide bar 204c, the first adjustment block 204d and the clamping piece 204f can be adjusted in position in the processing tank 102, so that the staff can better insert the wire into the relay 101. The first adjustment block 204d is arranged on the top of the slide bar 204c, and a first adjustment block 204d is arranged on one side to match with the pressing piece 201. The clamping piece 204f is combined, and two sliding bars 204c, first adjustment blocks 204d and clamping pieces 204f are each provided, and are arranged opposite to each other, so that after the wires are inserted, the effect of clamping and wrapping the wires can be achieved from both sides; a magnet 204e is provided at a position opposite to the first adjustment block 204d. Through the setting of the magnet 204e, after the connecting frame 105a is no longer in contact with the first adjustment block 204d, the two first adjustment blocks 204d can be brought close to each other by utilizing the principle of opposite charges attracting each other, thereby bringing the two clamping pieces 204f close to each other until they fit together, thereby achieving the effect of clamping and wrapping protection for the exposed wires.

[0047] Furthermore, a slider 202 is symmetrically arranged at the bottom of the clamping plate 201, and a connecting rod 203 is arranged on the outer side of the clamping plate 201. One end of the connecting rod 203 cooperates with the connecting frame 105a. Through the cooperation between the slider 202 and the connecting rod 203, the clamping plate 201 can be driven to move in the same direction when the connecting frame 105a moves toward the pull rod 103a, so as to facilitate better insertion of the wire into the relay 101. When the connecting frame 105a moves in the reverse direction, it drives the clamping plate 201 to move horizontally in the reverse direction, thereby achieving the clamping and fixing effect of the wire.

[0048] Furthermore, the lifting member 206 includes a accommodating shell 206a symmetrically arranged inside the processing tank 102, and an air cavity 206b is arranged at the bottom of the accommodating shell 206a, a piston 105d is nested at one end of the air cavity 206b, and a movable disk 206b-1 is nested at the other end of the air cavity 206b. Through the setting of the air cavity 206b, the movable disk 206b-1 can be pushed to move upward after the air inside the air cavity 206b is squeezed, and an adjustment plate 206c is slidably arranged on the top of the air cavity 206b, and a right-angle rod 206f is welded on one side of the adjustment plate 206c. The right-angle rod 206f is arranged at the bottom of the cover plate 207. Through the setting of the right-angle rod 206f, the adjustment plate 206c can be moved synchronously when it moves upward, thereby pushing the cover plate 207 on the top of the right-angle rod 206f to move upward, so as to facilitate better insertion of the wire into the relay 101.

[0049] At the same time; second adjustment blocks 206d are symmetrically arranged on both sides of the adjustment plate 206c, and a third spring 206e is arranged on the top of the second adjustment block 206d. The second adjustment block 206d and the third spring 206e are both arranged in the inner wall groove of the accommodating shell 206a. Through the cooperation between the second adjustment block 206d and the third spring 206e, the adjustment plate 206c can move up and down smoothly in the accommodating shell 206a. When the gas in the air cavity 206b is no longer squeezed, the adjustment plate 206c moves downward to restore the initial position, driving the right-angle rod 206f to move downward, so that the cover plate 207 moves downward. A limiting groove 206f-1 matching the right-angle rod 206f is opened on the outer wall of the accommodating shell 206a.

[0050] When in use, first pull the connecting frame 105a to move in the direction of the pull rod 103a, and the connecting rod 203 and the pressing plate 201 are driven by the connecting frame 105a to move horizontally in the same direction. The first adjusting block 204d moves to both sides under the action of the connecting frame 105a, driving the clamping plate 204f outside the first adjusting block 204d to move horizontally in the processing tank 102. Secondly, the connecting frame 105a drives the connecting plate 105b, the adjusting rod 105c and the piston 105d to move horizontally during the movement, and the gas in the air cavity 206b is squeezed by the piston 105d, so that the moving plate 206b at the top of the air cavity 206b is moved horizontally. -1 slides upward, driving the adjustment plate 206c to move up and down, and the right-angle rod 206f moves upward under the drive of the adjustment plate 206c, thereby realizing the position adjustment of the top cover plate 207 of the right-angle rod 206f, so as to facilitate the better insertion of the wire into the relay 101. When the wire is inserted, it moves in the opposite direction and repeats the above operation, which will not be repeated here. The pressing piece 201 and the clamping piece 204f move in the opposite direction to form a accommodating space with the contact terminal 205, thereby realizing the clamping protection of the wire, ensuring the contact between the wire and the contact terminal 205, ensuring the power-on of the wire, and avoiding the phenomenon of short circuit of the wire due to water ingress.
