Description

Technical Field

[0001] This application relates to the field of connectors, and more particularly to a high-voltage, low-current connector. Background Technology

[0002] Currently, with the rapid development of the automotive industry, the classification of automotive electronic products is partly based on compatibility designs for different automotive companies. Regardless of internal compatibility, the specific external requirements need to be determined, including installation location, structure, and electrical aspects. Various automotive parts are also constantly developing towards refinement and reliability, which places higher demands on the structural design of automotive connectors. However, automotive connectors and wiring harnesses are the carriers for electrical signal control of automobiles. Automotive connectors connect various control units of the vehicle to form a complete automotive electrical and electronic control system.

[0003] However, existing connectors used in automobiles often suffer from poor contact due to the swaying environment inside the vehicle during driving. Since connectors serve as bridges connecting internal vehicle components, poor contact of the metal wires or terminals can negatively impact the normal operation of these components. This situation needs improvement. Summary of the Invention

[0004] In order to improve the situation where poor contact of metal wires or terminals is caused by connector shaking, this application provides a high voltage and low current connector.

[0005] This application provides a high-voltage, low-current connector, which adopts the following technical solution:

[0006] A high-voltage, low-current connector includes a housing, an outer component, and wires. The housing has a first slot and a second slot on opposite sides. The outer component is disposed in the first slot, and the wires are disposed in the second slot. A plurality of contact terminals are spaced apart inside the housing. Each contact terminal includes a fixing part disposed inside the housing, a first contact part disposed on the fixing part near the first slot, and a second contact part disposed on the fixing part near the second slot. The housing has a backstop component for abutting against the contact terminals and a stop component for limiting the contact terminals. The housing also has an anti-disengagement component for limiting the distance between the housing and the outer component.

[0007] By adopting the above technical solution, the connector fixes the contact terminals inside the housing. The contact terminals are fixed inside the housing by the fixing part, and contact the external component through the first contact part and contact the wire through the second contact part, so that the connector can be interconnected with the internal parts of the vehicle through the contact terminals. The contact terminals are strengthened in the housing by the anti-retraction component and the stop component, and the stability between the connector and the external component is strengthened by the anti-disengagement component. The solution in this application can improve the stability of the automotive connector when connecting with the internal parts of the vehicle and improve the situation of poor contact of metal wire pieces or terminals caused by the connector shaking.

[0008] Optionally, the housing is provided with a fixing groove for placing the contact terminal, and the anti-reverse assembly includes an elastic sheet disposed on the side of the fixing part near the fixing groove, an elastic groove disposed on the side of the fixing groove near the elastic sheet and for the elastic sheet to be embedded, and an anti-reverse block disposed on the side of the second contact part away from the fixing part.

[0009] By adopting the above technical solution, when installing the contact terminal, the contact terminal is inserted into the housing from the second slot. When the elastic piece reaches the elastic groove, the elastic piece is embedded in the elastic groove. Then, the contact terminal is further limited by the anti-reverse block, thereby reducing the probability that the contact terminal will fall out of the fixed groove due to retraction.

[0010] Optionally, the stop assembly includes a first stop block disposed on the side of the fixing groove near the fixing part, a first stop part disposed on the side of the fixing part near the first stop block and abutting against the first stop block, a second stop part disposed on the side of the second contact part near the fixing part, and a second stop block disposed on the side of the fixing groove near the second stop part.

[0011] By adopting the above technical solution, when installing the contact terminal, the contact terminal is positioned in the fixing groove by the contact of the first stop part and the first stop block, and by the contact of the second stop part and the second stop block, thereby reducing the probability of the contact terminal falling out of the fixing groove.

[0012] Optionally, the anti-detachment component includes a clamping plate disposed on the top wall of the housing, a hand-held portion disposed on the side of the clamping plate away from the outer component, a clamping portion disposed on the side of the clamping plate near the outer component, and a clamping groove disposed on the side of the outer component near the clamping portion for the clamping portion to be inserted into. The housing is provided with a reset component for the clamping plate to spring back on the side near the clamping plate.

[0013] By adopting the above technical solution, when connecting the housing and the outer component, pressing the handle causes the clamping part to move away from the housing. When the outer component is installed into the first slot, releasing the handle causes the clamping part to move towards the housing via the reset assembly, so that the clamping part is embedded in the clamping slot, thereby enhancing the stability of the connection between the housing and the outer component. When the car is moving, if the clamping part bounces up due to vibration inside the car, the reset assembly causes the clamping part to quickly reset, so that the clamping part is embedded in the clamping slot, thereby reducing the probability of the connector connection falling off due to vibration caused by the car's movement.

[0014] Optionally, the reset assembly includes a first fixed shaft and a second fixed shaft disposed on the side of the housing near the clamping plate, a first clamping shaft disposed on the side of the first fixed shaft near the second fixed shaft, a second clamping shaft disposed on the side of the second fixed shaft near the first fixed shaft, a pin with one end passing through the first fixed shaft and the other end passing through the second fixed shaft, and a torsion spring disposed between the first clamping shaft and the second clamping shaft and fixedly sleeved on the pin. The two torsion arms of the torsion spring act on the housing and the clamping plate respectively, causing them to clamp together. The axes of the first fixed shaft, the second fixed shaft, the first clamping shaft and the second clamping shaft are on the same straight line.

[0015] By adopting the above technical solution, the first fixed shaft and the first clamping shaft abut together, the second fixed shaft and the second clamping shaft abut together, and the first clamping shaft and the first fixed shaft are rotatably connected by a pin, and the second clamping shaft and the second fixed shaft are rotatably connected. The torsion springs act on the housing and the clamping plate respectively, so that the two tend to clamp together. When the clamping plate springs up, the reaction force of the torsion spring makes the clamping part embed into the clamping groove, thereby improving the stability of the connector.

[0016] Optionally, the anti-retraction block includes an anti-retraction part disposed on the side of the fixing part near the second contact part and for abutting against the fixing part, a support part disposed on the side of the second contact part near the wire and for supporting the wire, and a first snap-fit ​​part and a second snap-fit ​​part disposed on the side of the support part near the housing. The housing is provided with a first snap-fit ​​groove for the first snap-fit ​​part to be inserted into on the side of the first snap-fit ​​part, and a second snap-fit ​​groove is provided on the side of the housing near the second snap-fit ​​part for the second snap-fit ​​part to be inserted into.

[0017] By adopting the above technical solution, the anti-reverse block reduces the probability of the contact terminal retracting and disengaging from the fixing groove by abutting against the fixing part. The anti-reverse block is embedded in the first locking groove by the first locking part and the second locking part is embedded in the second locking groove, so that the anti-reverse block and the housing form a relative lock, thereby enhancing the stability of the anti-reverse block installed in the housing.

[0018] Optionally, the first contact portion includes a first contact end and a second contact end disposed on opposite sides of the outer component. The first contact end and the second contact end are clamped to the outer component. The first contact end is provided with a plurality of first contact heads, and the second contact end is provided with a plurality of second contact heads.

[0019] By adopting the above technical solution, the contact terminal clamps the external component through the first contact end and the second contact end, thereby improving the stability of the external component mounted on the housing. By contacting the external component through multiple first contact heads and multiple second contact heads, the contact area is increased, and the situation of poor contact caused by unstable vehicle operation is reduced.

[0020] Optionally, at least two housings are provided, each housing has an outer wall with a mounting block, and each housing has a mounting groove on the side away from the mounting block. The two housings are assembled by embedding the mounting block into the mounting groove.

[0021] By adopting the above technical solution, the two housings are embedded in the mounting groove by the mounting block, so as to realize the simple assembly of the two housings, and the distance between the two housings is preferably 1.13mm.

[0022] Optionally, the second contact portion is provided with a contact hole through which the wire passes.

[0023] By adopting the above technical solution, the contact terminal better surrounds the wire through the contact hole, resulting in a larger contact area between the wire and the contact terminal. Furthermore, by surrounding the wire with holes, the probability of poor contact between the wire and the contact terminal is reduced.

[0024] Optionally, the side of the elastic sheet closest to the elastic groove is configured as an inclined surface.

[0025] By adopting the above technical solution, the inclined surface makes it easier for the elastic sheet to be embedded in the elastic groove, and reduces the damage to the shell caused by the elastic sheet when it impacts the inner wall of the elastic groove.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. The connector fixes the contact terminals inside the housing. The contact terminals are fixed inside the housing by a fixing part. They contact the external component through the first contact part and the wire through the second contact part, so that the connector can be interconnected with the internal parts of the vehicle through the contact terminals. The contact terminals are reinforced with anti-retraction components and stop components to enhance the stability of the contact terminals inside the housing. The stability of the connector and the external component is enhanced by anti-disengagement components. The solution in this application can improve the stability of the automotive connector when connected to the internal parts of the vehicle.

[0028] 2. When installing the contact terminal, the contact terminal is inserted into the housing through the second slot. When the elastic piece reaches the elastic groove, the elastic piece is embedded in the elastic groove. Then, the contact terminal is further limited by the anti-reverse block, thereby reducing the probability of the contact terminal coming out of the fixed groove due to retraction.

[0029] 3. When the car is moving, if the clamping part bounces up due to vibration inside the car, the reset component will quickly reset the clamping part, so that the clamping part is embedded in the clamping groove, reducing the probability of the connector connection falling off due to vibration caused by the car's movement.

[0042] The following is a further detailed description of this application.

[0043] This application discloses a high-voltage, low-current connector. (Refer to...) Figure 1 and Figure 2 The device includes a housing 1, an outer component 2, and a wire 3. The housing 1 has a first slot 4 and a second slot 5 on opposite sides. The outer component 2 is installed in the first slot 4, and the wire 3 is installed in the second slot 5. A plurality of contact terminals 6 are installed inside the housing 1. Each contact terminal 6 includes a fixing part 7, a first contact part 8, and a second contact part 9. The fixing part 7 is installed inside the housing 1, the first contact part 8 is installed on the side of the fixing part 7 near the first slot 4, and the second contact part 9 is installed on the side of the fixing part 7 near the second slot 5. The housing 1 is equipped with a backstop assembly for abutting against the contact terminal 6 and a stop assembly for limiting the contact terminal 6. The housing is also equipped with an anti-detachment assembly for limiting the distance between the housing 1 and the outer component 2.

[0044] In this embodiment, the connector fixes the contact terminal 6 inside the housing 1. The contact terminal 6 is fixed inside the housing 1 by the fixing part 7. It contacts the outer component 2 through the first contact part 8 and the wire 3 through the second contact part 9, so that the connector can be interconnected with the internal parts of the vehicle through the contact terminal 6. The contact terminal 6 is limited by the anti-retraction component and the stop component to enhance the stability of the contact terminal 6 inside the housing 1. The anti-detachment component enhances the stability of the connector installed on the outer component 2. The solution in this application can improve the stability of the automotive connector when connected to the internal parts of the vehicle.

[0045] Reference Figure 2 and Figure 3The housing 1 has a fixing groove 10 for placing the contact terminal 6. In this embodiment, the anti-retraction assembly includes an elastic sheet 11, an elastic groove 12, and an anti-retraction block 13. The elastic sheet 11 is installed on the side of the fixing part 7 near the fixing groove 10. The elastic groove 12 is opened on the side of the fixing groove 10 near the elastic sheet 11 and allows the elastic sheet 11 to be embedded. The anti-retraction block 13 is installed on the side of the second contact part 9 away from the fixing part 7. The side of the elastic sheet 11 near the elastic groove 12 is provided with a slope 41. The slope 41 makes it easier for the elastic sheet 11 to be embedded in the elastic groove 12 and reduces the damage to the housing 1 caused by the elastic sheet 11 when it impacts the inner wall of the elastic groove 12. The retraction block 13 includes a retraction stop 28, a support 29, a first latching part 30, a second latching part 31, a first latching groove 32, and a second latching groove 33. The retraction stop 28 is installed on the side of the fixing part 7 near the second contact part 9 and is used to abut against the fixing part 7. The support 29 is installed on the side of the second contact part 9 near the wire 3 and is used to support the wire 3. The first latching part 30 and the second latching part 31 are installed on the side of the support 29 near the housing 1. The first latching groove 32 is opened on the side of the housing 1 near the first latching part 30 and is used for the first latching part 30 to be inserted. The second latching groove 33 is opened on the side of the housing 1 near the second latching part 31 and is used for the second latching part 31 to be inserted.

[0046] In this embodiment, the first slot 4 is interconnected with the fixing slot 10, and the second slot 5 is also interconnected with the fixing slot 10. When installing the contact terminal 6, the contact terminal 6 enters the housing 1 through the second slot 5, causing the elastic piece 11 to conform to the inner wall of the second slot 5 and follow the contact terminal 6 into the housing 1. When the elastic piece 11 reaches the elastic slot 12, it pops out and embeds itself into the elastic slot 12. Then, the contact terminal 6 is further limited by the anti-reverse block 13. The anti-reverse block 13 abuts against the fixing part 7 through the anti-reverse part 28, reducing the probability of the contact terminal 6 regressing and disengaging from the fixing slot 10. The anti-reverse block 13 is embedded in the first locking slot 32 through the first locking part 30, and the second locking part 31 is embedded in the second locking slot 33, so that the anti-reverse block 13 and the housing 1 form a relative lock, enhancing the stability of the anti-reverse block 13 installed in the housing 1.

[0047] Reference Figure 3 and Figure 4In this embodiment, the stop assembly includes a first stop block 14, a first stop portion 15, a second stop portion 16, and a second stop block 17. The first stop block 14 is installed on the side of the fixing groove 10 near the fixing portion 7. The first stop portion 15 is installed on the side of the fixing portion 7 near the first stop block 14 and abuts against the first stop block 14. The second stop portion 16 is installed on the side of the second contact portion 9 near the fixing portion 7. The second stop block 17 is installed on the side of the fixing groove 10 near the second stop portion 16. In this embodiment, when installing the contact terminal 6, the contact terminal 6 enters the inner wall of the housing 1 from the second slot 5. During the installation process, the contact terminal 6 is positioned in the housing 1 by the abutment of the first stop portion 15 and the first stop block 14, and by the abutment of the second stop portion 16 and the second stop block 17. The forward movement of the contact terminal 6 is limited, thereby enhancing the accuracy of the positioning of the contact terminal 6 in the fixing groove 10.

[0048] Reference Figure 5 and Figure 6 In this embodiment, the anti-detachment component includes a clamping plate 18, a handheld part 19, a clamping part 20, and a clamping groove 21. The clamping plate 18 is mounted on the top wall of the housing 1. The handheld part 19 is mounted on the side of the clamping plate 18 away from the outer component 2. The clamping part 20 is mounted on the side of the clamping plate 18 near the outside. The clamping groove 21 is formed on the side of the outer component 2 near the clamping part 20 and allows the clamping part 20 to be inserted. A reset component for the clamping plate 18 to spring back is mounted on the side of the housing 1 near the clamping plate 18. In this embodiment, the reset component includes a first fixed shaft 22, a second fixed shaft 23, a first clamping shaft 24, a second clamping shaft 25, a pin 26, and a torsion spring 27. The first fixed shaft 22... The first clamping shaft 24 is installed on the side of the housing 1 near the clamping plate 18, the second clamping shaft 25 is installed on the side of the first fixed shaft 23 near the second fixed shaft 22, one end of the pin 26 passes through the first fixed shaft 22 and the other end passes through the second fixed shaft 23, and the torsion spring 27 is installed between the first clamping shaft 24 and the second clamping shaft 25 and is fixedly sleeved on the pin 26. The two torsion arms of the torsion spring 27 act on the first housing 1 and the clamping plate 18 respectively, so that the two tend to clamp together, and the axes of the first fixed shaft 22, the second fixed shaft 23, the first clamping shaft 24 and the second clamping shaft 25 are on the same straight line.

[0049] In this embodiment, when the housing 1 is installed on the outer component 2, pressing the handle 19 causes the clamping part 20 to move away from the housing 1. When the outer component 2 is installed into the first slot 4, releasing the handle 19 causes the clamping part 20 to move towards the housing 1 via the reset assembly, thus embedding the clamping part 20 into the clamping space. This reinforces the installation of the housing 1 on the outer component 2, enhancing its stability. When the car moves, if the clamping part 20 bounces due to vibrations inside the car, the reset assembly allows the clamping part 20 to quickly reset and embed into the clamping slot 21, reducing the impact of vibrations. The vibration generated by the car's movement may cause unstable connection between the connector and the external component 2; the reset assembly connects the first fixed shaft 22 and the first clamping shaft 24, the second fixed shaft 23 and the second clamping shaft 25, and then connects the first clamping shaft 24 and the first fixed shaft 22 through the pin 26, and the second clamping shaft 25 and the second fixed shaft 23 are rotatably connected. The torsion spring 27 acts on the housing 1 and the clamping plate 18 respectively, so that the two tend to clamp together. When the clamping plate 18 springs up, the reaction force of the torsion spring 27 makes the clamping part 20 embed into the clamping groove 21, thereby improving the stability of the connector.

[0050] Reference Figure 7 and Figure 8 The first contact portion 8 includes a first contact end 34 and a second contact end 35 installed on opposite sides of the outer component 2. The first contact end 34 and the second contact end 35 are clamped to the outer component 2. The first contact end 34 is equipped with a plurality of first contact heads 36, and the second contact end 35 is equipped with a plurality of second contact heads 37. The second contact portion 9 has a contact hole 40 for the wire 3 to pass through. The contact terminal 6 better surrounds the wire 3 through the contact hole 40, so that the contact area between the wire 3 and the contact terminal 6 is larger. Moreover, by surrounding the wire 3 with holes, the probability of poor contact between the wire 3 and the contact terminal 6 is reduced. In this embodiment, the contact terminal 6 clamps the outer component 2 through the first contact end 34 and the second contact end 35, which improves the stability of the outer component 2 installed on the housing 1. By contacting the outer component 2 through the plurality of first contact heads 36 and the plurality of second contact heads 37, the contact area is increased, and the situation of poor contact caused by unstable vehicle operation is reduced.

[0051] Reference Figure 9 and Figure 10 At least two housings 1 are installed. An installation block 38 is installed on the outer wall of the housing 1. An installation groove 39 is opened on the side of the housing 1 away from the installation block 38. The two housings 1 are assembled by embedding the installation block 38 into the installation groove 39. In the embodiment of this application, the two housings 1 are easily assembled by embedding the installation block 38 into the installation groove 39. The distance between the two housings 1 is preferably 1.13mm.

[0052] The implementation principle of a high-voltage, low-current connector according to an embodiment of this application is as follows: The connector fixes the contact terminal 6 inside the housing 1. The contact terminal 6 is fixed inside the housing 1 by the fixing part 7. It contacts the external component 2 through the first contact part 8 and the wire 3 through the second contact part 9, so that the connector can be interconnected with the internal parts of the automobile through the contact terminal 6. When installing the contact terminal 6, the contact terminal 6 enters the housing 1 through the second slot 5, so that the elastic piece 11 conforms to the inner wall of the second slot 5 and follows the contact terminal 6 into the housing 1. When the elastic piece 11 reaches the elastic groove 12, the elastic piece 11 pops out and embeds into the elastic groove 12. Then, the contact terminal 6 is further limited by the anti-reverse block 13. The anti-reverse block 13 abuts against the fixing part 7 through the anti-reverse part 28, reducing the contact terminal 6 from falling out of the fixing groove due to retraction. With a probability of 10, the anti-reverse block 13 is embedded in the first locking groove 32 through the first locking part 30 and the second locking part 31 is embedded in the second locking groove 33, so that the anti-reverse block 13 and the housing 1 form a relative lock, which enhances the stability of the anti-reverse block 13 installed in the housing 1; then, through the abutment of the first stop part 15 and the first stop block 14, and the abutment of the second stop part 16 and the second stop block 17, the contact terminal 6 is positioned in the housing 1, and the forward movement of the contact terminal 6 is limited, which enhances the accuracy of the contact terminal 6 in the fixing groove 10; the outer wall of the housing 1 is reinforced by the anti-detachment component to enhance the stability of the connector installed on the outer part 2. The solution in this application can improve the stability of the automotive connector when connected to the internal parts of the vehicle, and improve the situation where the metal wire pieces or terminals are not in contact due to the shaking of the connector.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
