Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of electrical connectors, and more specifically, to an electrical connector based on a waterproof component. Background Art
[0002] A connector, also known as a connector and a socket in China, generally refers to an electrical connector. That is, a device that connects two active devices, transmits current or signals, and currently, waterproof connectors are mostly used in the market.
[0003] Regarding connectors, there are many existing technologies, for example: Chinese Patent Publication No. CN222015777U discloses a sealed circular electrical connector, which relates to the field of connectors. It includes a limit ring fixedly arranged on the surface of the middle part of the socket, and an outer sealing ring sleeved on the surface of the socket is arranged at the lower end of the limit ring; an inner limit ring is fixedly arranged in the upper half of the inner cavity of the socket, a connection core passing through the inner cavity of the socket is inserted in the middle of the inner limit ring, a first sealing ring is arranged between the connection core and the inner limit ring, a fixing ring is sleeved and fixed on the outer side of the connection core, the upper end of the fixing ring abuts against the lower end of the inner limit ring through a thin sealing strip, a thin sealing ring is embedded in the inner side of one end of the fixing ring away from the inner limit ring, and one side of the thin sealing ring abuts against and seals the connection core; an inner second sealing ring is embedded at the position of the inner cavity of the socket opposite to the thin sealing ring, and a accommodation space is reserved between the inner side of the inner second sealing ring and the lower end of the fixing ring to seal each connection and splicing position of the connector, effectively preventing water molecules and dust from entering the inside of the connector, thereby avoiding corrosion or short circuit of the connection terminals.
[0004] However, in the actual use process, there are still some problems: 1. Traditional electrical connectors mainly rely on sealing rings to achieve sealing and waterproofing between plugs. Its working principle is to squeeze the sealing ring when the plug is docked with the socket, so that it fills the gap to block water. However, frequent plugging and unplugging operations will cause irreversible damage to the sealing ring, which increases the sealing gap and significantly reduces the waterproof performance; 2. During the use of the electrical connector, the stability of the connecting head wire is crucial. In traditional electrical connectors, the connection method between the wire and the connection terminal is mostly plugging. When subjected to external force touch, this connection method is extremely prone to loosening, seriously affecting the transmission quality of electrical signals, causing signal attenuation, distortion, and even signal interruption, thereby affecting the normal operation of the entire electrical system and increasing the equipment failure risk and maintenance cost.
[0005] In view of this, we propose an electrical connector based on a waterproof component. Summary of the Invention
[0006] The purpose of the present invention is to provide an electrical connector based on a waterproof component to solve the problems raised in the above background art.
[0007] To achieve the above object, the object of the present invention is to provide an electrical connector based on a waterproof component, including a connector head and a connector seat. The connector head includes a housing, and a pin is arranged inside the housing. A ring block is arranged at the end of the connector head. The connector seat includes a housing, and a socket is arranged inside the housing. Limiting columns are arranged on both sides of the housing. The limiting columns are hollow with an open end. A ring groove is arranged at the end of the housing. A waterproof component is arranged inside the ring groove. The waterproof component includes a hollow ring, a sponge pad is arranged inside the hollow ring, through grooves are arranged on the surface of the hollow ring, a compression spring is arranged between the ring groove and the hollow ring, the ring block is in snap-fit with the ring groove. In the natural state, the hollow ring is flush with the end of the ring groove under the action of the compression spring. Vent holes are arranged at the end of the ring block, and the vent holes are arranged in an annular array at the end of the ring block, and the vent holes penetrate through the ring block to the outside of the housing.
[0008] As a further improvement of the technical solution, the vent holes are frustum-shaped, and the diameter of the vent holes gradually decreases from the ring block to the housing direction.
[0009] As a further improvement of the technical solution, a rubber pad is arranged on the surface of the ring block. When the ring block is in fit with the ring groove, the gap between them is filled by the rubber pad, so that the ring block and the ring groove are in a sealed state.
[0010] As a further improvement of the technical solution, the through grooves are arranged in an annular array on the surface of the hollow ring, and the hollow ring is pushed to slide along the inner wall of the ring groove.
[0011] As a further improvement of the technical solution, guiding columns are arranged on both sides of the housing, and the guiding columns slide inside the inner wall of the limiting columns. At the same time, the moving direction of the housing is limited during the movement of the guiding columns.
[0012] As a further improvement of the technical solution, anti-disengagement components are arranged at the top and bottom of the housing. The housing drives the anti-disengagement components to move on the surface of the housing. When the pin is in fit with the socket, the anti-disengagement components move to the card slots to fix the housing and the socket.
[0013] As a further improvement of the technical solution, the anti-disengagement components include support frames arranged at the top and bottom of the housing. A support rod is arranged at the end of the support frame. An arc-shaped clamping plate is rotatably arranged on the surface of the support rod. The arc-shaped clamping plate moves to the card slot for buckling to fix the housing and the housing.
[0014] As a further improvement of the technical solution, a torsion spring is arranged on the surface of the support rod. The two ends of the torsion spring are respectively connected to the support frame and the arc-shaped clamping plate. By rotating the arc-shaped clamping plate on the surface of the support rod, the arc-shaped clamping plate releases the buckling of the card slot.
[0015] As a further improvement of the technical solution, the arc-shaped clamping plate forms an angle of 15° with the horizontal plane under the action of the torsion spring. When the arc-shaped clamping plate moves above the clamping groove, the arc-shaped clamping plate is automatically clamped into the clamping groove under the action of the torsion spring.
[0016] As a further improvement of the technical solution, anti-oxidation coatings are applied to the surfaces of both the outer shell and the housing.
[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In the electrical connector based on the waterproof component, a ring block is provided at the end of the outer shell. When the ring block is fully adapted to the ring groove, the tightness between the pin and the socket is in a normal state. When there is water stain on the surface of the electrical connector and the water body infiltrates into the ring groove through the connection port, due to the extrusion of the hollow ring during the adaptation process of the ring block and the ring groove, the hollow ring slides on the inner wall of the ring groove and always fits against the side wall of the ring block. At this time, the water body flows along the ring block into the hollow ring, and the sponge pad absorbs the infiltrated water body, preventing the water body from continuing to flow into the housing, thereby ensuring the service life of the electrical connector.
[0018] 2. In the electrical connector based on the waterproof component, by opening ventilation holes at the end of the ring block, when the sponge pad absorbs water, the ventilation holes accelerate the exchange of air between the air inside the ring groove, enabling the water body adsorbed inside the sponge pad to dry quickly. At the same time, if water continuously drips onto the interface between the outer shell and the housing, since the ventilation holes are arranged in an annular array at the end of the ring block and the diameter of the ventilation holes gradually decreases from the ring block to the outer shell direction, the excess water can be drained through the ventilation holes.
[0019] 3. In the electrical connector based on the waterproof component, when installing the connector head and the connector seat, the guide post is inserted into the inner wall of the limit post, so that the outer shell can always maintain horizontal stability when moving inside the housing, preventing the pin from bending due to the position deviation during the movement of the outer shell, thereby improving the service life of the connector head. Similarly, when it is necessary to disassemble the connector head and the connector seat, under the action of the guide post, the pin always moves horizontally with the housing, preventing the pin from shaking and bending when moving away from the socket.

[0024] Embodiment 1 provides an electrical connector based on a waterproof component. Refer to Figures 1-4As shown in the figure, it includes a connector head 100 and a connector base 200. The connector head 100 includes a housing 101. Inside the housing 101, there is a pin 102. At the end of the connector head 100, there is an annular block 104. The connector base 200 includes a housing 201. Inside the housing 201, there is a socket 202. On both sides of the housing 201, there are limit posts 203. The limit posts 203 are hollow with an open end. At the end of the housing 201, there is an annular groove 205. Inside the annular groove 205, there is a waterproof component 300. The waterproof component 300 includes a hollow ring 301. Inside the hollow ring 301, there is a sponge pad 302. On the surface of the hollow ring 301, there are through slots 303. Between the annular groove 205 and the hollow ring 301, there is a compression spring 304. The annular block 104 is snap-fitted with the annular groove 205. In the natural state, the hollow ring 301 is flush with the end of the annular groove 205 under the action of the compression spring 304. At the end of the annular block 104, there are ventilation holes 106. The ventilation holes 106 are arranged in an annular array at the end of the annular block 104. The ventilation holes 106 penetrate through the annular block 104 to the outside of the housing 101.
[0025] Considering that when the surface of the electrical connector is splashed with water, in order to avoid internal water immersion and cause damage to the electrical connector, therefore, a waterproof component 300 is provided inside the annular groove 205. The waterproof component 300 includes a hollow ring 301. Inside the hollow ring 301, there is a sponge pad 302. On the surface of the hollow ring 301, there are through slots 303. The through slots 303 are arranged in an annular array on the surface of the hollow ring 301, pushing the hollow ring 301 to slide and fit against the inner wall of the annular groove 205. The annular block 104 is snap-fitted with the annular groove 205. In the natural state, the hollow ring 301 is flush with the end of the annular groove 205 under the action of the compression spring 304. When the electrical connector is being fitted, by inserting the housing 101 into the housing 201, the pin 102 is fitted with the socket 202. In order to avoid the pin 102 being too tight or too loose when inserted into the inner wall of the socket 202 and affecting the normal transmission of electrical signals, therefore, an annular block 104 is provided at the end of the housing 101. When the annular block 104 is fully fitted with the annular groove 205, at this time, the tightness between the pin 102 and the socket 202 is in a normal state. When there is water stain on the surface of the electrical connector and the water body infiltrates into the annular groove 205 through the connection port, since the annular block 104 squeezes the hollow ring 301 during the fitting process with the annular groove 205, the hollow ring 301 slides on the inner wall of the annular groove 205 and always fits against the side wall of the annular block 104. At this time, the water body flows along the annular block 104 into the inside of the hollow ring 301, and the sponge pad 302 absorbs the infiltrated water body, preventing the water body from continuing to flow into the housing 201, thereby ensuring the service life of the electrical connector. When the sponge pad 302 absorbs external water, in order to accelerate its drying and facilitate repeated waterproof operations, ventilation holes 106 are provided at the end of the ring block 104. The ventilation holes 106 are arranged in an annular array at the end of the ring block 104. The ventilation holes 106 penetrate through the ring block 104 to the outside of the outer shell 101. The ventilation holes 106 are in a frustum shape, and the diameter of the ventilation holes 106 gradually decreases along the direction from the ring block 104 to the outer shell 101. By providing the ventilation holes 106 at the end of the ring block 104, when the sponge pad 302 absorbs water inside, the air exchange between the air inside the ventilation holes 106 and the air inside the annular groove 205 is accelerated, so that the water adsorbed inside the sponge pad 302 dries quickly. At the same time, if water continuously drips into the interface between the outer shell 101 and the housing 201, since the ventilation holes 106 are arranged in an annular array at the end of the ring block 104 and the diameter of the ventilation holes 106 gradually decreases along the direction from the ring block 104 to the outer shell 101, the excess water can be discharged through the ventilation holes 106, so that even when the electrical connector is under water flow, a good waterproof effect can be achieved in a short time.
[0026] When the ring block 104 is adapted to the annular groove 205, in order to prevent gaps between them, resulting in poor waterproof performance, a rubber pad 105 is provided on the surface of the ring block 104. When the ring block 104 is adapted to the annular groove 205, the rubber pad 105 fills the gaps between them, making the space between the ring block 104 and the annular groove 205 airtight. By providing the rubber pad 105 on the surface of the ring block 104, since the rubber pad 105 has a certain elasticity, when the ring block 104 is adapted to the annular groove 205, the rubber pad 105 is extruded against the inner wall of the annular groove 205, so that the rubber pad 105 blocks the gaps between the ring block 104 and the annular groove 205, thereby improving the waterproof performance of the electrical connector.
[0027] Embodiment 2 provides an electrical connector based on a waterproof component. Refer to Figures 1-8As shown, it includes a connector head 100 and a connector socket 200. The connector head 100 includes a housing 101. Inside the housing 101, there is a pin 102. At the end of the connector head 100, there is an annular block 104. The connector socket 200 includes a housing body 201. Inside the housing body 201, there is a socket 202. On both sides of the housing body 201, there are limit posts 203. The limit posts 203 are hollow with an open end. At the end of the housing body 201, there is an annular groove 205. Inside the annular groove 205, there is a waterproof component 300. The waterproof component 300 includes a hollow ring 301. Inside the hollow ring 301, there is a sponge pad 302. On the surface of the hollow ring 301, there are through grooves 303. Between the annular groove 205 and the hollow ring 301, there is a compression spring 304. The annular block 104 is snap-fitted with the annular groove 205. In the natural state, the hollow ring 301 is flush with the end of the annular groove 205 under the action of the compression spring 304. At the end of the annular block 104, there are ventilation holes 106. The ventilation holes 106 are arranged in an annular array at the end of the annular block 104. The ventilation holes 106 penetrate through the annular block 104 to the outside of the housing 101; Considering that when the surface of the electrical connector is splashed with water, in order to prevent water from entering the interior and causing damage to the electrical connector, therefore, a waterproof component 300 is provided inside the annular groove 205. The waterproof component 300 includes a hollow ring 301. Inside the hollow ring 301, there is a sponge pad 302. On the surface of the hollow ring 301, there are through grooves 303. The through grooves 303 are arranged in an annular array on the surface of the hollow ring 301. Push the hollow ring 301 to slide along the inner wall of the annular groove 205. The annular block 104 is snap-fitted with the annular groove 205. In the natural state, the hollow ring 301 is flush with the end of the annular groove 205 under the action of the compression spring 304. When the electrical connector is being mated, by inserting the housing 101 into the housing body 201, the pin 102 is mated with the socket 202. In order to prevent the pin 102 from being inserted too tightly or too loosely into the inner wall of the socket 202, affecting the normal transmission of electrical signals, therefore, an annular block 104 is provided at the end of the housing 101. When the annular block 104 is fully mated with the annular groove 205, at this time, the tightness between the pin 102 and the socket 202 is in a normal state. When there is water stain on the surface of the electrical connector and the water body enters the annular groove 205 through the connection port, since the annular block 104 squeezes the hollow ring 301 during the mating process with the annular groove 205, the hollow ring 301 slides on the inner wall of the annular groove 205 and always fits against the side wall of the annular block 104. At this time, the water body flows along the annular block 104 into the inside of the hollow ring 301, and the sponge pad 302 absorbs the infiltrated water body, preventing the water body from continuing to flow into the housing body 201, thus ensuring the service life of the electrical connector; When the sponge pad 302 absorbs external water, in order to accelerate its drying and facilitate repeated waterproof operations, ventilation holes 106 are provided at the end of the ring block 104. The ventilation holes 106 are arranged in an annular array at the end of the ring block 104. The ventilation holes 106 penetrate through the ring block 104 to the outside of the outer shell 101. The ventilation holes 106 are in the shape of a truncated cone, and the diameter of the ventilation holes 106 gradually decreases along the direction from the ring block 104 to the outer shell 101. By providing the ventilation holes 106 at the end of the ring block 104, when the sponge pad 302 absorbs water, the air is accelerated to exchange with the air inside the annular groove 205 through the ventilation holes 106, so that the water adsorbed inside the sponge pad 302 dries quickly. At the same time, if water continuously drips into the interface between the outer shell 101 and the housing 201, since the ventilation holes 106 are arranged in an annular array at the end of the ring block 104 and the diameter of the ventilation holes 106 gradually decreases along the direction from the ring block 104 to the outer shell 101, the excess water can be discharged through the ventilation holes 106, so that even when the electrical connector is under water flow, a good waterproof effect can be achieved in a short time; When installing and disassembling the connector 100 and the connector base 200, in order to prevent the outer shell 101 from shaking inside the inner wall of the housing 201 and causing the pin 102 to bend and damage, guide posts 103 are provided on both sides of the outer shell 101. The guide posts 103 slide inside the inner wall of the limit post 203. At the same time, the movement direction of the outer shell 101 is limited during the movement of the guide posts 103. When installing the connector 100 and the connector base 200, the guide posts 103 are inserted into the inner wall of the limit post 203, so that the outer shell 101 can always maintain horizontal stability when moving inside the housing 201, and prevent the position of the outer shell 101 from shifting during movement and causing the pin 102 to bend, thereby improving the service life of the connector 100. Similarly, when it is necessary to disassemble the connector 100 and the connector base 200, under the action of the guide posts 103, the pin 102 always moves horizontally with the housing 201, avoiding the pin 102 from shaking and bending when moving away from the socket 202.
[0028] Embodiment 3 provides an electrical connector based on a waterproof component. Refer to Figures 1-8As shown in the figure, it includes a connector head 100 and a connector socket 200. The connector head 100 includes a housing 101. Inside the housing 101, there is a pin 102. At the end of the connector head 100, there is a ring block 104. The connector socket 200 includes a housing 201. Inside the housing 201, there is a socket 202. On both sides of the housing 201, there are limit posts 203. The limit posts 203 are hollow with an open end. At the end of the housing 201, there is a ring groove 205. Inside the ring groove 205, there is a waterproof component 300. The waterproof component 300 includes a hollow ring 301. Inside the hollow ring 301, there is a sponge pad 302. On the surface of the hollow ring 301, there are through grooves 303. Between the ring groove 205 and the hollow ring 301, there is a compression spring 304. The ring block 104 is snap-fitted with the ring groove 205. In the natural state, the hollow ring 301 is flush with the end of the ring groove 205 under the action of the compression spring 304. At the end of the ring block 104, there are ventilation holes 106. The ventilation holes 106 are arranged in an annular array at the end of the ring block 104. The ventilation holes 106 penetrate through the ring block 104 to the outside of the housing 101.
[0029] Considering that when the surface of the electrical connector is splashed with water, in order to avoid internal water immersion and cause damage to the electrical connector, therefore, a waterproof component 300 is provided inside the ring groove 205. The waterproof component 300 includes a hollow ring 301. Inside the hollow ring 301, there is a sponge pad 302. On the surface of the hollow ring 301, there are through grooves 303. The through grooves 303 are arranged in an annular array on the surface of the hollow ring 301. Push the hollow ring 301 to slide along the inner wall of the ring groove 205. The ring block 104 is snap-fitted with the ring groove 205. In the natural state, the hollow ring 301 is flush with the end of the ring groove 205 under the action of the compression spring 304. When the electrical connector is being mated, by inserting the housing 101 into the housing 201, the pin 102 is mated with the socket 202. In order to avoid the pin 102 being inserted too tightly or too loosely into the inner wall of the socket 202, which affects the normal transmission of electrical signals, therefore, a ring block 104 is provided at the end of the housing 101. When the ring block 104 is fully mated with the ring groove 205, at this time, the tightness between the pin 102 and the socket 202 is in a normal state. When there is water stain on the surface of the electrical connector and the water body enters the ring groove 205 through the connection port, due to the extrusion of the hollow ring 301 during the mating process of the ring block 104 and the ring groove 205, the hollow ring 301 slides on the inner wall of the ring groove 205 and always fits against the side wall of the ring block 104. At this time, the water body flows along the ring block 104 into the hollow ring 301, and the sponge pad 302 absorbs the infiltrated water body to prevent the water body from continuing to flow into the housing 201, thereby ensuring the service life of the electrical connector. When the sponge pad 302 absorbs external water, in order to accelerate its drying and facilitate repeated waterproof operations, vent holes 106 are provided at the end of the ring block 104. The vent holes 106 are arranged in an annular array at the end of the ring block 104, penetrate through the ring block 104 to the outside of the outer shell 101, are in the shape of a truncated cone, and the diameter of the vent holes 106 gradually decreases along the direction from the ring block 104 to the outer shell 101. By providing the vent holes 106 at the end of the ring block 104, when the sponge pad 302 absorbs water, the air exchange between the air and the air inside the annular groove 205 is accelerated through the vent holes 106, so that the water adsorbed inside the sponge pad 302 is quickly dried. At the same time, if water continuously drips into the interface between the outer shell 101 and the housing 201, since the vent holes 106 are arranged in an annular array at the end of the ring block 104 and the diameter of the vent holes 106 gradually decreases along the direction from the ring block 104 to the outer shell 101, the excess water can be discharged through the vent holes 106, so that the electrical connector can achieve a good waterproof effect in a short time even when it is under water flow.
[0030] When the ring block 104 is adapted to the annular groove 205, in order to prevent gaps between them, resulting in poor waterproof performance, a rubber pad 105 is provided on the surface of the ring block 104. When the ring block 104 is adapted to the annular groove 205, the gap between them is filled by the rubber pad 105, so that the space between the ring block 104 and the annular groove 205 is sealed. By providing the rubber pad 105 on the surface of the ring block 104, since the rubber pad 105 has a certain elasticity, when the ring block 104 is adapted to the annular groove 205, the rubber pad 105 is extruded against the inner wall of the annular groove 205, so that the rubber pad 105 blocks the gap between the ring block 104 and the annular groove 205, thereby improving the waterproof performance of the electrical connector.
[0031] When installing and disassembling the connector head 100 and the connector seat 200, in order to prevent the outer shell 101 from shaking inside the inner wall of the housing 201, resulting in bending and damage of the pins 102, guide posts 103 are provided on both sides of the outer shell 101. The guide posts 103 slide inside the inner wall of the limit posts 203, and at the same time, the moving direction of the outer shell 101 is limited during the movement of the guide posts 103. When installing the connector head 100 and the connector seat 200, the guide posts 103 are inserted into the inner wall of the limit posts 203, so that the outer shell 101 can always maintain horizontal stability when moving inside the housing 201, avoiding the pins 102 from bending due to the position deviation of the outer shell 101 during movement, thereby improving the service life of the connector head 100. Similarly, when it is necessary to disassemble the connector head 100 and the connector seat 200, under the action of the guide posts 103, the pins 102 always move horizontally with respect to the housing 201, avoiding the pins 102 from shaking and bending when moving away from the socket 202; When the connector 100 and the socket 200 are installed, in order to prevent loosening and falling off between them, anti-detachment components 400 are provided at the top and bottom of the housing 101. The housing 101 drives the anti-detachment components 400 to move on the surface of the housing 201. When the pin 102 is adapted to the socket 202, the anti-detachment components 400 move to the card slot 204 to fix the housing 101 and the socket 202. The anti-detachment components 400 include support frames 401 provided at the top and bottom of the housing 101. At the end of the support frame 401, there is a support rod 402. An arc-shaped clamping plate 403 is rotatably provided on the surface of the support rod 402. The arc-shaped clamping plate 403 moves to the card slot 204 for buckling to fix the housing 101 and the housing 201. When the housing 101 moves, the arc-shaped clamping plate 403 rotates on the surface of the support rod 402 so that the arc-shaped clamping plate 403 is placed on the outer wall of the housing 201 for movement. When the arc-shaped clamping plate 403 moves above the card slot 204, the arc-shaped clamping plate 403 is rotated to the inner wall of the card slot 204 so that the arc-shaped clamping plate 403 is clamped on the inner wall of the card slot 204 for fixation, thereby preventing loosening between the connector 100 and the socket 200 and improving the connection stability of the electrical connector.
[0032] Considering that the arc-shaped clamping plate 403 under the housing 101 rotates on the surface of the support rod 402 when moving under the action of gravity, when the arc-shaped clamping plate 403 moves below the card slot 204, it cannot buckle the card slot 204, affecting the stability between the connector 100 and the socket 200 and resulting in unstable electrical signal transmission. Therefore, a torsion spring 404 is provided on the surface of the support rod 402. The two ends of the torsion spring 404 are respectively connected between the support frame 401 and the arc-shaped clamping plate 403. By rotating the arc-shaped clamping plate 403 on the surface of the support rod 402, the arc-shaped clamping plate 403 is released from buckling the card slot 204. The arc-shaped clamping plate 403 forms an angle of 15° with the horizontal plane under the action of the torsion spring 404. When the arc-shaped clamping plate 403 moves above the card slot 204, the arc-shaped clamping plate 403 is automatically clamped into the card slot 204 under the action of the torsion spring 404. The torsion spring 404 limits the arc-shaped clamping plate 403. When the arc-shaped clamping plate 403 moves above the card slot 204, it is driven by the action of the torsion spring 404 to automatically rotate and buckle to the inner wall of the card slot 204, enabling stable connection between the connector 100 and the socket 200 and improving the stability during the use of the electrical connector.
[0033] Considering that during the use of the electrical connector, it is always exposed to the air, which is likely to cause oxidation of the housing 101 and the housing 201 over a long time. Therefore, an anti-oxidation coating is applied to the surfaces of the housing 101 and the housing 201 to isolate the housing 101 and the housing 201 from the external air, thereby increasing their service life.
[0034] During specific use, when the electrical connector is being adapted, the housing 101 is inserted into the interior of the housing body 201, enabling the pin 102 to be adapted to the socket 202. To prevent the pin 102 from being inserted too tightly or too loosely into the inner wall of the socket 202, which may affect the normal transmission of electrical signals, a ring block 104 is provided at the end of the housing 101. When the ring block 104 is fully adapted to the ring groove 205, the tightness between the pin 102 and the socket 202 is in a normal state. When there is water stain on the surface of the electrical connector and the water body infiltrates into the ring groove 205 through the connection port, since the hollow ring 301 is squeezed during the adaptation process of the ring block 104 and the ring groove 205, the hollow ring 301 slides on the inner wall of the ring groove 205 and always adheres to the side wall of the ring block 104. At this time, the water body flows along the ring block 104 into the interior of the hollow ring 301, and the sponge pad 302 absorbs the infiltrated water body, preventing the water body from continuing to flow into the interior of the housing body 201, thereby ensuring the service life of the electrical connector; By opening ventilation holes 106 at the end of the ring block 104, when the sponge pad 302 absorbs water, the ventilation holes 106 accelerate the exchange of air between the air inside the ring groove 205, enabling the water body adsorbed inside the sponge pad 302 to dry quickly. At the same time, if water continues to drip onto the interface between the housing 101 and the housing body 201, since the ventilation holes 106 are arranged in an annular array at the end of the ring block 104 and the diameter of the ventilation holes 106 gradually decreases from the ring block 104 to the direction of the housing 101, the excess water can be discharged through the ventilation holes 106, enabling the electrical connector to achieve a good waterproof effect in a short time even when it is under water flow; When installing the connector head 100 and the connector base 200, the guide post 103 is inserted into the inner wall of the limit post 203, so that the housing 101 can always maintain horizontal stability when moving inside the housing body 201, preventing the position of the housing 101 from shifting during movement and causing the pin 102 to bend, thereby increasing the service life of the connector head 100. Similarly, when it is necessary to disassemble the connector head 100 and the connector base 200, under the action of the guide post 103, the pin 102 always moves horizontally with respect to the housing body 201, preventing the pin 102 from shaking and bending when moving away from the socket 202; The arc-shaped clamping plate 403 is limited by the torsion spring 404. The arc-shaped clamping plate 403 is rotated on the surface of the support rod 402, and the arc-shaped clamping plate 403 is placed on the outer wall of the housing body 201 for horizontal movement. When the arc-shaped clamping plate 403 moves above the card slot 204, when the arc-shaped clamping plate 403 moves above the card slot 204, driven by the action of the torsion spring 404, the arc-shaped clamping plate 403 automatically rotates and snaps into the inner wall of the card slot 204, enabling the stable connection between the connector head 100 and the connector base 200 and improving the stability during the use of the electrical connector.
