Description

Technical Field

[0001] This application belongs to the technical field of connectors and relates to a high-voltage-resistant connector plug. Background Art

[0002] Connectors are used to build a connection bridge between circuits that are blocked or isolated in a circuit, so as to achieve a predetermined function. With the rapid development of technology, in order to ensure the stability of the circuit in large equipment, there is a greater current demand for connectors, and high-voltage connectors have emerged as the times require.

[0003] High-voltage connectors require high insulation and breakdown voltage resistance in the working environment. When traditional high-voltage connectors face the current demand after exceeding 300A, they increase the volume to meet the power supply demand. Due to the limited installation space, increasing the volume of the connector restricts the installation of other components, and at the same time reduces the connection stability between the entire connector plug and socket. Summary of the Invention

[0004] In order to improve the defects that traditional high-voltage connectors have a large volume, which restricts the installation of other components, and at the same time reduces the connection stability between the entire connector plug and socket, this application provides a high-voltage-resistant connector plug.

[0005] A high-voltage-resistant connector plug provided by this application adopts the following technical solutions:

[0006] A high-voltage-resistant connector plug includes:

[0007] A pin for crimping with a wire to transmit optoelectronic signals, and a clamping ring is arranged in the middle of the pin;

[0008] A housing for fixing and protecting the pin, and the pin is located inside the housing;

[0009] An insulating component for insulation, the insulating component is located between the pin and the housing, and the insulating component includes a first pin insulating tube and a second pin insulating tube; the pin passes through the first pin insulating tube and is located inside the first pin insulating tube, the clamping ring abuts against the first pin insulating tube, the second pin insulating tube is located inside the first pin insulating tube and is in close contact with the first pin insulating tube, and the second pin insulating tube abuts against the end face of the clamping ring away from the first pin insulating tube.

[0010] By adopting the above technical solution, the wire is crimped with the pin, and the pin is electrically connected to the external socket part to transmit optical and electrical signals. The purpose of high-voltage resistance is achieved by arranging an insulating component between the pin and the housing. When impacted by an instantaneous high voltage from the outside, the voltage is transmitted from the first pin insulator to the second pin insulator through the pin. The extended insulating component and the superposition of the insulating components increase the creepage distance, thereby enhancing the voltage resistance of the connector and improving the applicability of the connector.

[0011] Optionally, the first pin insulating tube is provided with a first flange and a first receiving groove. The first flange is located on the inner wall of the first pin insulating tube. The second pin insulating tube is located in the first receiving groove, and the second pin insulating tube is simultaneously pressed against the clamping ring and the bottom of the first receiving groove. The second pin insulating tube is provided with a third flange and a fourth flange. The third flange is located on the inner wall of the second pin insulating tube, and the fourth flange is located on the outer wall of the second pin insulating tube. The clamping ring is located between the first flange and the third flange, and the fourth flange is pressed against the end of the first pin insulating tube close to the second pin insulating tube.

[0012] By adopting the above technical solution, the second pin insulating tube is located in the first receiving groove, and the clamping ring is located between the first flange and the third flange. When a force is applied to the second pin insulating tube, the first flange and the third flange simultaneously press against the clamping ring, and the installation position of the pin is fixed by restricting the clamping ring, increasing the installation stability of the pin, reducing looseness generated during the connection between the pin and the external socket, and further improving the connection stability between the pin and the socket.

[0013] Optionally, a connecting inner tube for enhancing the installation stability between the outer shell and the first pin insulating tube is arranged between the outer shell and the first pin insulating tube. The connecting inner tube is provided with a clamping block for clamping with the outer shell and a second receiving groove for pressing against the first pin insulating tube. The first pin insulating tube is provided with a second flange.

The outer shell is provided with a clamping groove for cooperating with the clamping block, and the clamping block is located in the clamping groove and clamped with the outer shell.

[0014] By adopting the above technical solution, the connecting inner tube is clamped with the clamping groove of the outer shell through the clamping block. The first pin insulator is located in the second receiving groove and pressed against the bottom of the second receiving groove. When a force is applied to the second pin insulator, the installation stability between the outer shell and the first pin insulating tube is enhanced through the connecting inner tube under the cooperation of the clamping block and the clamping groove. The operator can complete the connection between the pin and the external socket by holding the outer shell, and at the same time, the installation stability of the pin is improved.

[0015] Optionally, the insulation assembly further includes an insulator fixing tube located in the second receiving groove and pressing against the bottom of the second receiving groove; a limiting flange is provided on the inner wall of the insulator fixing tube. The first pin insulation tube and the second pin insulation tube are located within the insulator fixing tube, and the end face of the fourth flange away from the first pin insulation tube presses against the limiting flange.

[0016] By adopting the above technical solution, a force is applied to the insulation fixing tube, so that the limiting flange presses against the fourth flange, and the fourth flange presses against the end of the first pin insulation tube away from the pin, thereby fixing the first pin insulation tube and the second pin insulation tube by the insulator fixing tube, reducing the displacement between the first pin insulation tube and the second pin insulation tube, and further increasing the installation stability of the pin.

[0017] Optionally, it further includes a heat conduction tube for conducting the heat of the pin. The heat conduction tube has a heat absorption part for absorbing the heat generated by the pin and a heat conduction part for diffusing the heat. The heat absorption part is sleeved within the second pin insulation tube. The heat absorption part is provided with a cavity for accommodating a heat conduction medium. The ends of the insulator fixing tube and the connecting inner tube away from the pin press against the heat conduction part, and the heat conduction part is in close contact with the outer wall and the end of the heat conduction part away from the pin is in contact with the air.

[0018] By adopting the above technical solution, when a high voltage passes through the connector loop or the pin works for a long time, heat generation will occur, resulting in an increase in the temperature of the pin and the contact part with the pin. The heat absorption part of the heat conduction tube absorbs the accumulated heat, thereby transferring the heat to the heat conduction medium in the cavity. The heat of the pin part is taken away by the heat conduction medium, and then dissipated through the heat conduction part of the heat conduction tube; the outer shell part in contact with the heat conduction part increases the contact area between the heat conduction tube and the air, further enhancing the heat conduction effect.

[0019] Optionally, an installation inner tube for installing a wire is sleeved within the heat conduction tube. The installation inner tube is located within the cavity. The two ends of the installation inner tube respectively press against the inner wall of the cavity; first sealing rings for blocking the leakage of the heat conduction medium in the cavity are respectively provided at the two ends of the installation inner tube; the heat absorption part is provided with an installation hole for the installation inner tube to pass through, and the first sealing ring is located within the installation hole and is in sealing cooperation with the heat absorption part and the installation inner tube.

[0020] By adopting the above technical solution, the wire is crimped with the pin by passing through the installation inner tube. The installation inner tube, on the one hand, plays a role in isolating the wire from the heat conduction medium, and on the other hand, limits the movement direction and position of the wire; the first sealing ring cooperates with the installation inner tube and the heat absorption part for sealing cooperation to prevent the heat conduction medium in the cavity from leaking out from the gap between the installation inner tube and the installation hole, affecting the heat conduction effect and the normal use of the connector.

[0021] Optionally, it further includes a tail cap. One end of the tail cap is located inside the heat-conducting part and is threadedly connected to the heat-conducting part. The tail cap is provided with a wire passing channel for the wire to pass through. The inner wall of the wire passing channel is provided with a first waterproof layer to prevent moisture from seeping in, and the first waterproof layer is fixedly connected to the wire.

[0022] By adopting the above technical solution, the wire enters the installation hole through the wire passing channel, then passes through the installation inner tube and is crimped with the pin. The first waterproof layer is fixedly connected to the inner wall of the wire passing channel and the wire, preventing moisture from entering the tail cap through the wire passing channel and then entering the installation inner tube, resulting in the failure of the connector connection. The first waterproof layer increases the waterproof performance of the high-voltage-resistant connector and expands the usage environment of the high-voltage-resistant connector.

[0023] Optionally, it further includes a wire clamp for fixing the wire. The wire clamp is provided with a clamping part for clamping the wire. The clamping part is located at the end of the wire clamp close to the tail cap. The tail cap is provided with a third receiving groove for receiving the clamping part and is in contact with the bottom of the third receiving groove, and the other end of the wire clamp is in contact with the heat-conducting part.

[0024] By adopting the above technical solution, the tail cap is matched with the heat-conducting part through threads. During the process of rotating the tail cap, the wire clamp located in the third receiving groove gradually moves towards the heat-conducting part as the tail cap moves, so that the wire clamp is in contact with the end face of the heat-conducting part facing the tail cap. At the same time, the clamping part clamps the wire under the pressing action of the bottom of the third receiving groove, reducing the detachment of the wire from the pin due to external force and improving the installation stability of the wire.

[0025] Optionally, a second sealing ring for waterproofing is provided between the wire clamp and the heat-conducting part, and the outer peripheral wall of the second sealing ring is in contact with the inner peripheral wall of the heat-conducting part.

[0026] By adopting the above technical solution, the second sealing ring restricts the infiltration of moisture through the threaded connection between the tail cap and the heat-conducting part, enhancing the waterproof performance of the connector; during the process of rotating the tail cap, the wire clamp gradually moves towards the heat-conducting part as the tail cap moves, and the second sealing ring located between the wire clamp and the heat-conducting part is gradually pressed by the wire clamp, further enhancing the waterproof performance of the connector.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. High voltage resistance. The wire is crimped with the pin, and the pin is electrically connected to the external socket part to transmit optical and electrical signals. The purpose of high voltage resistance is achieved by setting an insulating component between the pin and the housing. When subjected to the impact of an instantaneous high voltage from the outside, the voltage is transmitted from the first pin insulator to the second pin insulator through the pin, and the creepage distance is increased through the lengthened insulating component and the superposition of the insulating components, thereby enhancing the voltage resistance of the connector and improving the applicability of the connector.

[0029] 2. Good heat dissipation performance. When current passes through the connector loop, the pins will generate heat, causing the temperature of the pins and the contact parts with the pins to rise. The heat absorption part of the heat pipe absorbs the accumulated heat, transfers the heat to the heat-conducting medium in the solute chamber, and the heat of the pin part is taken away by the heat-conducting medium, and then dissipated through the heat-conducting part of the heat pipe; the outer shell part in contact with the heat-conducting part increases the contact area between the heat pipe and the air, further enhancing the heat-conducting effect.

[0030] 3. Excellent waterproof performance. The wire enters the installation hole through the wire passing channel, then passes through the installation inner tube and is crimped with the pin. The first waterproof layer is fixedly connected to the inner wall of the wire passing channel and the wire, preventing moisture from entering the tail cap from the wire passing channel; the second sealing ring restricts the infiltration of moisture through the threaded connection between the tail cap and the heat-conducting part, enhancing the waterproof performance of the connector and expanding the usage environment of the high-voltage-resistant connector.

The wire clamp 7 is located inside the tail cap 5 and presses against the heat conducting tube 4. The tail cap 5 is threadedly connected to the heat conducting tube 4. In this embodiment, the heat conducting tube 4 is threadedly connected to the housing 2.

[0040] Referring to Figure 2 and Figure 3 , the insulating component 3 includes a first pin insulating tube 31 and a second pin insulating tube 32. The pin 1 passes through the first pin insulating tube 31 and is located inside the first pin insulating tube 31. The second pin insulating tube 32 is located inside the first pin insulating tube 31 and is in close contact with the first pin insulating tube 31. A clamping ring 11 is provided in the middle of the pin 1. The clamping ring 11 presses against the first pin insulating tube 31, and the second pin insulating tube 32 presses against the end face of the clamping ring 11 away from the first pin insulating tube 31.

[0041] Referring to Figure 3 , in this embodiment, the first pin insulating tube 31 is provided with a first flange 311 and a first receiving groove 313. The first flange 311 is located on the inner wall of the first pin insulating tube 31. The second pin insulating tube 32 is located inside the first receiving groove 313 and presses against both the clamping ring 11 and the bottom of the first receiving groove 313 at the same time. The second pin insulating tube 32 is provided with a third flange 321 and a fourth flange 322. The third flange 321 is located on the inner wall of the second pin insulating tube 32, and the fourth flange 322 is located on the outer wall of the second pin insulating tube 32. The clamping ring 11 is located between the first flange 311 and the third flange 321. The fourth flange 322 presses against the end of the first pin insulating tube 31 closer to the second pin insulating tube 32. The wire is crimped to the pin 1. The pin 1 is electrically connected to an external socket part to transmit optical and electrical signals. When subjected to an impact of an instantaneous high voltage from the outside, the voltage is transmitted from the first pin insulator to the second pin insulator through the pin 1. The creepage distance is increased through the superposition of the first pin insulator and the second pin insulator, thereby enhancing the voltage resistance of the connector and achieving the purpose of high-voltage resistance.

[0042] Referring to Figure 2 and Figure 3, the outer shell 2 is a hollow circular tube. In this embodiment, the outer shell 2 is made of stainless steel. The outer shell 2 is provided with a clamping groove 22. A connecting inner tube 21 for enhancing the installation stability between the outer shell 2 and the first needle insulating tube 31 is arranged between the outer shell 2 and the first needle insulating tube 31. The connecting inner tube 21 is provided with a clamping block 211 that matches the size of the clamping groove 22. The clamping block 211 is located in the clamping groove 22 and is clamped with the outer shell 2.

[0043] The connecting inner tube 21 is provided with a second receiving groove 212 for pressing against the first needle insulating tube 31. The first needle insulating tube 31 is provided with a second flange 312. The second flange 312 is located on the outer wall of the first needle insulating tube 31, and the second flange 312 is located in the second receiving groove 212 and presses against the bottom of the second receiving groove 212. The connecting inner tube 21 is clamped with the clamping groove 22 of the outer shell 2 through the clamping block 211. The first needle insulator is located in the second receiving groove 212 and presses against the bottom of the second receiving groove 212. When a force is applied to the second needle insulator, the first flange 311 and the third flange 321 simultaneously press against the clamping ring 11, and the installation position of the insertion pin 1 is fixed by restricting the clamping ring 11. At the same time, with the cooperation of the clamping block 211 and the clamping groove 22, the installation stability between the outer shell 2 and the first needle insulating tube 31 is enhanced through the connecting inner tube 21; the operator can complete the connection between the insertion pin 1 and the external socket by holding the outer shell 2, and at the same time, the installation stability of the insertion pin 1 is improved, thereby improving the connection stability between the insertion pin 1 and the socket.

[0044] To further increase the installation stability of the insertion pin 1, the insulating component 3 further includes an insulator fixing tube 33. The insulator fixing tube 33 is located in the second receiving groove 212 and presses against the bottom of the second receiving groove 212; a limiting flange 331 is arranged on the inner wall of the insulator fixing tube 33. The first needle insulating tube 31 and the second needle insulating tube 32 are located in the insulator fixing tube 33, and the end face of the fourth flange 322 away from the first needle insulating tube 31 presses against the limiting flange 331. When a force is applied to the insulating fixing tube, the limiting flange 331 presses against the fourth flange 322, and the fourth flange 322 presses against the end of the first needle insulating tube 31 away from the insertion pin 1, so that the insulator fixing tube 33 fixes the first needle insulating tube 31 and the second needle insulating tube 32, reducing the displacement between the first needle insulating tube 31 and the second needle insulating tube 32.

[0045] Refer to Figure 3 and Figure 4, the heat pipe 4 has a heat absorption part 41 for absorbing the heat generated by the pin 1 and a heat conduction part 42 for dissipating heat. In this embodiment, the heat absorption part 41 is sleeved inside the second pin insulating tube 32; the heat absorption part 41 is provided with a separating flange and a cavity. The direction of the diameter of the separating flange is perpendicular to the length direction of the heat pipe 4, and the separating flange divides the cavity into a solute chamber 411 for accommodating the heat conduction medium and a heat conduction chamber. The heat conduction medium preferably selects heat conduction silica gel in this embodiment. When current passes through the connector loop, the pin 1 will generate heat, causing the temperature of the pin 1 and the contact part with the pin 1 to rise. The heat absorption part 41 of the heat pipe 4 absorbs the accumulated heat, transfers the heat to the heat conduction medium in the solute chamber 411, takes away the heat of the pin 1 part through the heat conduction medium, and then dissipates heat through the heat conduction part 42 of the heat pipe 4. One end of the insulator fixing tube 33 and the connecting inner tube 21 away from the pin 1 presses against the heat conduction part 42, the heat conduction part 42 is in close contact with the outer wall, and one end of the heat conduction part 42 away from the pin 1 is in contact with the air. The part of the housing 2 in contact with the heat conduction part 42 increases the contact area between the heat pipe 4 and the air, further enhancing the heat conduction effect.

[0046] An installation inner tube 43 for installing a wire is sleeved inside the heat pipe 4. The installation inner tube 43 is located in the solute chamber 411, and both ends of the installation inner tube 43 press against the inner wall of the solute chamber 411 respectively. The wire is press-connected to the pin 1 by passing through the installation inner tube 43. On the one hand, the installation inner tube 43 plays a role in isolating the wire from the heat conduction medium, and on the other hand, it limits the movement direction and position of the wire.

[0047] First sealing rings 431 for blocking the leakage of the heat conduction medium in the solute chamber 411 are respectively arranged at both ends of the installation inner tube 43. The heat absorption part 41 is provided with an installation hole 412 for the installation inner tube 43 to pass through. The first sealing rings 431 are located in the installation hole 412 and are in sealing cooperation with the heat absorption part 41 and the installation inner tube 43. The first sealing rings 431 cooperate with the installation inner tube 43 and the heat absorption part 41 to be in sealing cooperation, preventing the heat conduction medium in the solute chamber 411 from leaking out from the gap between the installation inner tube 43 and the installation hole 412, affecting the heat conduction effect and the normal use of the connector.

[0048] Refer to Figure 2 and Figure 3 , one end of the tail cap 5 is located inside the heat conduction part 42 and is threadedly connected to the heat conduction part 42. The tail cap 5 is provided with a wire passing channel 51 for the wire to pass through. A first waterproof layer for preventing moisture from seeping in is arranged on the inner wall of the wire passing channel 51, and the first waterproof layer is fixedly connected to the wire. The wire enters the installation hole 412 through the wire passing channel 51, then passes through the installation inner tube 43 and is press-connected to the pin 1. The first waterproof layer is fixedly connected to the inner wall of the wire passing channel 51 and the wire, preventing moisture from entering the tail cap 5 from the wire passing channel 51.

[0049] Further, a second waterproof layer for preventing moisture from seeping in is also provided on the inner wall of the wire passing channel 51. The outer wall of the second waterproof layer is fixedly connected to the inner wall of the wire passing channel 51, and the inner wall of the second waterproof layer is fixedly connected to the outer wall of the wire. The second waterproof layer further enhances the waterproof performance of the high-voltage resistant connector and expands the usage environment of the high-voltage resistant connector. In this embodiment, the first waterproof layer is obtained by sucking air at one end of the connecting inner tube 21 close to the pin 1 and pouring glue towards the part where the wire passing channel 51 is connected to the wire. After the first waterproof layer is completely dry, the second waterproof layer is formed in the same way to further enhance the waterproof effect.

[0050] The wire clamp 7 is provided with a clamping part 71 for clamping the wire. The tail cap 5 is provided with a third receiving groove 54 for receiving the clamping part 71. One end of the clamping part 71 close to the tail cap 5 abuts against the bottom of the third receiving groove 54, and the end of the wire clamp 7 away from the clamping part 71 abuts against the heat conducting part 42. In this embodiment, the clamping part 71 is located at one end of the wire clamp 7 close to the tail cap 5, and the inner wall of the third receiving groove 54 is inclined towards the direction away from the pin 1; by evenly and equidistantly arranging avoiding grooves on the clamping part 71, when the tail cap 5 is rotated in cooperation with the thread, the wire clamp 7 located in the third receiving groove 54 gradually moves towards the heat conducting part 42 as the tail cap 5 moves, so that the wire clamp 7 abuts against the end face of the heat conducting part 42 towards the tail cap 5. At the same time, the clamping part 71 clamps the wire under the pressing action of the inclined inner wall of the third receiving groove 54, reducing the detachment of the wire from the pin 1 caused by external force dragging and improving the installation stability of the wire.

[0051] To further enhance the waterproof performance of the connector, a second sealing ring 6 for waterproofing is provided between the wire clamp 7 and the heat conducting part 42. The outer peripheral wall of the second sealing ring 6 abuts against the inner peripheral wall of the heat conducting part 42. The second sealing ring 6 restricts the infiltration of moisture through the threaded connection between the tail cap 5 and the heat conducting part 42, enhancing the waterproof performance of the connector; during the rotation of the tail cap 5, the wire clamp 7 gradually moves towards the heat conducting part 42 as the tail cap 5 moves, and the second sealing ring 6 located between the wire clamp 7 and the heat conducting part 42 is gradually pressed by the wire clamp 7, further enhancing the waterproof performance of the connector.

[0052] The implementation principle of a high-voltage-resistant connector plug in an embodiment of the present application is as follows: The wire enters the wire clamp 7 through the wire passing channel 51, and then enters the installation inner tube 43 through the installation hole 412 to be crimped with the pin 1 for the transmission of optoelectronic signals. During the operation of the pin 1 or when it is impacted by an instantaneous high voltage from the outside, the voltage is transmitted from the first pin insulator to the second pin insulator through the pin 1, and then to the insulator fixing tube 33. The extended insulation component 3 and the superposition of the insulation component 3 increase the creepage distance, thereby enhancing the voltage resistance of the connector. When a high voltage passes through the connector loop, or when the pin 1 works for a long time, heat generation will occur, causing the temperature of the pin 1 and the contact part with the pin 1 to rise. The heat absorption part 41 of the heat conduction tube 4 absorbs the accumulated heat, thereby transferring the heat to the heat conduction medium in the mass chamber 411. The heat of the pin 1 part is carried away by the heat conduction medium, and then part of the heat is dissipated through the heat conduction part 42 of the heat conduction tube 4; another part of the heat is transmitted to the air through the outer shell 2 in contact with the heat conduction part 42.
