Description

[0026] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following provides a detailed description of the specific embodiments of the present invention with reference to the accompanying drawings of the specification.

[0027] Example 1, referring to Figures 1 to 7 , which is the first embodiment of the present invention. This embodiment provides an electrical connector with a protection mechanism 3, which can achieve the effect that the components inside the female end of the electrical connector are easily damaged when not connected. It includes a female part 1 and a male part 2. A protection mechanism 3 and a connection mechanism 4 are provided between the female part 1 and the male part 2. The setting of the protection mechanism 3 can isolate the components inside the female part 1 from the external air when the female part 1 and the male part 2 are separated, avoiding damage to the internal components by external air and dust when the female part 1 is not in use. When the male part 2 is inserted into the female part 1, the protection mechanism 3 can be unfolded to enable the male part 2 to smoothly enter the female part 1 to realize the basic connection function between the male part 2 and the female part 1. This device is applicable to equipment with the male part 2 installed on walls and cabinets, and can be effectively protected when it is idle. The setting of the connection mechanism 4 is used to ensure the basic connection function between the male part 2 and the female part 1; The protection mechanism 3 includes a positioning component 30 and a movable component 31. The positioning component 30 includes two positioning arcs 300 located inside the mother component 1. The positioning arcs 300 are made of plastic. The cross section of the positioning arcs 300 is semicircular. The axes of the two positioning arcs 300 are located on the same straight line. Both ends of the positioning arcs 300 are fixedly connected with positioning rods 301. Both ends of the positioning arcs 300 are provided with slide seats 302. The two slide seats 302 are connected by elastic ropes 303. The elastic ropes 303 are woven from elastic fibers. The elastic ropes 303 are The cross-section of 03 is rectangular. When in use, the elastic rope 303 stretches and accumulates elastic potential energy, thereby effectively driving the two slides 302 to reset. A cylinder 304 is fixedly connected to the bottom of the slide 302, and the cylinder 304 is fixedly connected to the slide 302. The setting of the cylinder 304 can effectively drive the slide 302 to move, and during the movement of the cylinder 304, the slide 302 is driven to translate. Because the slides 302 and the cylinders 304 correspond to each other in pairs, when the slide 302 moves, the two cylinders 304 move together.

[0028] Among them, the positioning arc 300 is a relatively fixed component, which is used to fix the positioning rod 301. When the positioning rod 301 is fixed, the slide 302 slides on the positioning rod 301 to realize the movement of the slide 302. When the two slides 302 are closed at the same time, the socket of the mother component 1 can be closed, thereby preventing external air and dust from damaging its internal components when the mother component 1 is not in use.

[0029] The movable component 31 includes a disc 310 located at the bottom of the slide 302 . The disc 310 is provided with a resistance groove 311 corresponding to the cylinder 304 . The end of the disc 310 away from the slide 302 is rotatably connected to a sealing plate 312 . The bottom of the sealing plate 312 is fixedly connected to a protective cover 314 via a spring 313 .

[0030] Furthermore, a circular hole is provided at the center of the disc 310 to avoid the use of the mother component 1. The diameter of the circular hole is smaller than the width of the slide 302. The slide 302 is used to seal the middle of the disc 310 to prevent external water vapor and air from damaging the components inside the mother component 1. The setting of the resistance groove 311 is used to drive the cylinder 304. During the movement of the resistance groove 311, the inside of the resistance groove 311 always resists the cylinder 304, forcing the cylinder 304 to move. Because the positioning rod 301 limits the slide 302, the cylinder 304 can only move along the direction of the slide 302 during the movement. At the same time, it drives the slide seat 302 to move. The sealing plate 312 is set to seal the top of the interference groove 311 to prevent dust and water vapor in the external air from entering the interior of the female component 1. The spring 313 is set to resist the protective cover 314 to prevent the protective cover 314 from being too close to the sealing plate 312, and at the same time it can resist the male component 2. When the male component 2 is inserted into the female component 1, the spring 313 is in a contracted state. Its elastic potential energy can separate the female component 1 and the male component 2 more quickly when the male component 2 is separated from the female component 1. Rapidly separating the female component 1 and the male component 2 can protect the safety of the user to a certain extent.

[0031] The two ends of the spring 313 are fixedly connected to the sealing plate 312 and the protective cover 314 respectively. The slide seat 302 is slidably connected to the positioning rod 301. The abutment groove 311 is arc-shaped, and the inner wall of the abutment groove 311 fits the outer wall of the cylinder 304. The opposite sides of the two slide seats 302 are provided with rubber layers.

[0032] During operation, the disc 310 is rotated, and the rotation of the disc 310 drives the interference groove 311 to rotate. During the rotation of the interference groove 311, an interference force is applied to the cylinder 304, forcing the cylinder 304 to move. Because the positioning rod 301 limits the slide seat 302, the cylinder 304 can only move along the direction of the slide seat 302 during the movement. During the movement of the cylinder 304, the slide seat 302 is also driven to move. The sealing plate 312 is set to close the top of the interference groove 311.

[0033] In summary, the device is suitable for equipment where the male component 2 is installed on the wall and the cabinet, and can be effectively protected when it is idle. The setting of the protection mechanism 3 can isolate the components inside the female component 1 from the external air when the female component 1 is separated from the male component 2, thereby preventing external air and dust from damaging its internal components when the female component 1 is not in use. The setting of the protection mechanism 3 can cause the male component 2 to be expanded when the male component 2 is inserted into the female component 1, so that the male component 2 can smoothly enter the female component 1, thereby realizing the basic connection function between the male component 2 and the female component 1.

[0034] Example 2, reference Figures 2 to 7, which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a connection mechanism 4 of an electrical connector with a protection mechanism 3, solving the connection problem of the electrical connector, and it includes a connection mechanism 4.

[0035] The connection mechanism 4 includes a driving component 40 and a positioning mechanism 41. The driving component 40 includes an inner groove 400 opened inside the protective cover 314. The inner wall of the inner groove 400 is fixedly connected with a rotating block 401. The rotating block 401 is fixedly connected with the disc 310. The number of the inner groove 400 and the rotating block 401 is multiple, and they are distributed in an annular array inside the protective cover 314. The cross section of the rotating block 401 is circular.

[0036] Furthermore, the cross section of the inner groove 400 is rectangular, and the inner groove 400 is arranged in an arc shape. During the process of the inner groove 400 moving vertically upward, it can effectively drive the moving of the rotating block 401. The setting of the rotating block 401 can drive the moving of the disc 310. When the inner groove 400 moves upward and passes through the limit of the rotating block 401, it can drive the disc 310 to rotate. When the disc 310 rotates, it can drive the sliding disc to rotate, thereby exposing the connecting part of the female part 1, facilitating the connection between the male part 2 and the female part 1. The number of the inner groove 400 and the rotating block 401 is multiple, so that when the male part 2 applies force, the force can be transmitted to the disc 310 more evenly.

[0037] The positioning mechanism 41 includes a cylinder 410 fixedly connected to the bottom of the female part 1, and a side cylinder 411 fixedly connected to the top of the male part 2. The bottom edge of the cylinder 410 is arc-shaped. A connecting vertical groove 412 is opened on the outer wall of the cylinder 410. A side groove 413 is opened on one side of the connecting vertical groove 412. A fixing groove 414 is opened at the bottom of the side groove 413. The side cylinder 411 is fixedly connected with a clamping column 415 and a marking block 416 corresponding to the connecting vertical groove 412.

[0038] Among them, the setting of the cylinder 410 can effectively limit the side cylinder 411, and when in use, it can better insert the male part 2 into the female part 1. The setting of the clamping column 415 can effectively adapt to the fixing groove 414. During the use of this device, first align the marking block 416 with the connecting vertical groove 412 and move it into the inside. When moving to the end, rotate it so that the clamping column 415 passes through the connecting vertical groove 412 and enters the side groove 413. At this time, the male part 2 compresses the spring 313, making it in a contracted state. At this time, release the side cylinder 411, and the elastic potential energy of the spring 313 is released. When the clamping column 415 enters the fixing groove 414, the fixing work can be completed.

[0039] The outer wall of the cylinder 410 is in contact with the inner wall of the side cylinder 411. The cross-sections of the cylinder 410 and the side cylinder 411 are circular. The inner wall of the side cylinder 411 is in contact with the outer wall of the protective cover 314. The marking block 416 is made of a fluorescent material, which can better locate the marking block 416. The marking block 416 and the clamping post 415 are located on the same vertical line, which can better bring the clamping post 415 into the connecting vertical groove 412 and is arranged in a triangular shape. The protective cover 314 is slidably connected to the disc 310 in the vertical direction. The cross-section of the protective cover 314 is circular, and the protective cover 314 is made of plastic material.

[0040] All other structures are the same as those in Embodiment 1.

[0041] In summary, when the male part 2 is idle, it can be effectively protected. The setting of the protection mechanism 3 can isolate the components inside the female part 1 from the external air when the female part 1 and the male part 2 are separated.

[0042] Embodiment 3, referring to Figures 2 to 7 , is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides a female part 1 and a male part 2 of an electrical connector with a protection mechanism 3, which solves the connection problem of the electrical connector. It includes that the female part 1 includes a first wire 10. One end of the first wire 10 close to the male part 2 is fixedly connected with a fixing plate 11 and a limiting seat 12 respectively. A receiving battery cell 13 is fixedly connected inside the limiting seat 12. The receiving battery cell 13 is electrically connected to the first wire 10. The male part 2 includes a second wire 20. A docking seat 21 is fixedly connected to the bottom of the second wire 20. A plugging groove 22 is opened at the center inside the docking seat 21. A docking guide post 23 is fixedly connected to the second wire 20 inside the plugging groove 22. A docking battery cell cylinder 24 is slidably connected to the outside of the docking guide post 23. The bottom of the docking battery cell cylinder 24 and the plugging groove 22 are connected by a reset spring piece 25. The docking battery cell cylinder 24 is slidably connected to the docking guide post 23.

[0043] Furthermore, the reset elastic piece 25 can effectively drive the docking battery cell cylinder 24 to move. During the use of the device, the male part 2 moves towards the female part 1. The docking battery cell cylinder 24 first contacts the sliding seat 302, and when the sliding seat 302 is not fully opened, the male part 2 continues to move along the direction of the female part 1. At this time, the reset elastic piece 25 contracts and accumulates elastic potential energy. When the sliding seat 302 is fully opened, the elastic potential energy of the reset elastic piece 25 is released, causing the docking battery cell cylinder 24 to directly impact towards the receiving battery cell 13, so that the docking battery cell cylinder 24, the receiving battery cell 13 and the docking guide post 23 are connected. This device can achieve rapid combination. When the docking battery cell cylinder 24, the receiving battery cell 13 and the docking guide post 23 are separated, the reset elastic piece 25 will first deform and accumulate elastic potential energy. When the friction between the docking battery cell cylinder 24 and the receiving battery cell 13 disappears instantaneously, the elastic potential energy of the reset elastic piece 25 will drive the docking battery cell cylinder 24 to separate more quickly. The slow separation and combination between the male part 2 and the female part 1 may lead to an unstable on-off process, generating instantaneous voltage spikes or current surges, which may damage precision electronic components. Rapid separation and combination can shorten the time of this unstable state.

[0044] The cross-section of the reset elastic piece 25 is circular. The reset elastic piece 25 is arranged in an arc shape. The number of reset elastic pieces 25 is multiple, and multiple reset elastic pieces 25 are distributed in an annular array between the insertion slot 22 and the docking battery cell cylinder 24. The outer wall of the docking battery cell cylinder 24 is slidably connected to the inner wall of the insertion slot 22, and the docking battery cell cylinder 24 is adapted to the receiving battery cell 13.

[0045] All other structures are the same as those in Embodiment 2.

[0046] During use, insert the male part 2 into the female part 1. First, align the marking block 416 with the connecting vertical slot 412 and move it into the inside. When moving to the end, rotate it so that the clamping column 415 passes through the connecting vertical slot 412 and enters the side slot 413. At this time, the male part 2 compresses the spring 313, making it in a contracted state. Then release the side cylinder 411, and the elastic potential energy of the spring 313 is released. When the clamping column 415 enters the fixing slot 414, the fixing work can be completed. During this process, the protective cover 314 moves upward. When the protective cover 314 moves, it moves vertically upward in the inner slot 400. During the movement, it drives the rotating block 401 to rotate around the axis of the disc 310, and the rotation of the rotating block 401 can drive the disc 310 to rotate. Rotate the disc 310. During the rotation of the disc 310, it drives the abutting groove 311 to rotate. During the rotation of the abutting groove 311, a abutting force is applied to the cylinder 304, forcing the cylinder 304 to displace. Also, because the positioning rod 301 limits the sliding seat 302, the cylinder 304 can only move along the direction of the sliding seat 302 during the movement. During the movement of the cylinder 304, it drives the sliding seat 302 to move at the same time, thus exposing the connecting part of the female part 1, facilitating the connection between the male part 2 and the female part 1. The male part 2 moves towards the female part 1. The docking battery cell cylinder 24 first contacts the sliding seat 302. When the sliding seat 302 is not fully opened, the male part 2 continues to move along the direction of the female part 1. At this time, the reset elastic piece 25 contracts and accumulates elastic potential energy. When the sliding seat 302 is fully opened, the elastic potential energy of the reset elastic piece 25 is released, causing the docking battery cell cylinder 24 to directly impact towards the receiving battery cell 13, so that the docking battery cell cylinder 24, the receiving battery cell 13 and the docking guide post 23 can be connected.

[0047] In summary, this device is applicable to equipment with the male part 2 installed on the wall and the cabinet. When it is idle, it can be effectively protected. The setting of the protection mechanism 3 can isolate the components inside the female part 1 from the external air when the female part 1 and the male part 2 are separated.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
