Description

Technical Field

[0001] This invention relates to the field of connecting component technology, and in particular to a connector. Background Technology

[0002] With the continuous advancement of automotive intelligence and electrification, and the booming development of in-vehicle entertainment systems and intelligent driving, higher demands have been placed on automotive power supply. The traditional 12V electrical architecture can no longer meet the ever-increasing power demand, and higher voltage and power have become an inevitable trend, leading to the emergence of 48V or higher voltage electrical architectures.

[0003] However, in 48V or higher voltage architectures, the increased voltage and power expose connectors to higher safety risks. When connectors are connected to or disconnected from circuits with 48V or higher voltage, electric arcs may occur on the connector pin terminals and socket terminals, which may lead to serious damage to the connector. Summary of the Invention

[0004] This invention provides a connector to solve the technical problem in the related art where, when a circuit with a voltage of 48V or higher is connected to or disconnected, an electric arc is generated at the connector's pin terminals and socket terminals, leading to connector damage.

[0005] This invention provides a connector, comprising: The socket has a power socket terminal at the bottom; An interlocking assembly is movably disposed within the socket and has a signal jack terminal at the bottom; CPA component, which is located on top of the interlock assembly; A plug is located at the bottom of the socket, and the plug is provided with power pin terminals and signal pin terminals; When the plug is used to connect to the socket, the power pin terminal is first connected to the power socket terminal, and then the CPA component is driven to move the interlock assembly. The signal pin terminal is connected to the signal socket terminal, so that the power pin terminal and the power socket terminal are energized. When the plug is used to separate from the socket, the CPA component is driven to move the interlocking assembly, the signal pin terminal separates from the signal jack terminal first, the power pin terminal is de-energized from the power jack terminal, and then the power pin terminal separates from the power jack terminal again.

[0006] In some embodiments, the interlocking component further includes: A square block is vertically disposed within the socket, and a signal jack terminal is provided at the bottom of the square block; A cylindrical rod is located on top of the square block and passes through a circular hole in the socket. The top of the cylindrical rod has a groove that engages with the CPA component.

[0007] In some embodiments, the top of the cylindrical rod is further provided with a step, and the top of the step has a beveled structure.

[0008] In some embodiments, the signal jack terminal includes: A square hole is provided through the bottom of the square block; A conductive sheet is disposed within the square hole and is used for electrical connection with the signal pin terminal; The pin port is located on the outside of the conductive sheet and at the bottom of the square block.

[0009] In some embodiments, the conductive sheet includes: A square box, wherein the square box is disposed within the square hole; Two sets of spring contacts are symmetrically arranged on both sides of the square housing, and the two sets of spring contacts respectively engage with the signal pin terminals.

[0010] In some embodiments, the conductive sheet further includes: The spring is located at the bottom of the square box and engages with the stepped hole located in the square hole.

[0011] In some embodiments, the interlocking component further includes: The first sealing ring is sleeved on the tail of the cylindrical rod and sealed to the circular hole.

[0012] In some embodiments, the CPA component includes: A locking seat, which is horizontally disposed on one side of the socket; A boss is provided vertically below the locking seat. The top of the boss abuts against the lug crossbeam on the socket and the plate end bracket on the plug. The plate end bracket is used to press the boss away from the lug crossbeam. A crossbeam is provided on one side of the locking seat, and a frustum is provided on the crossbeam, which engages with the groove.

[0013] In some embodiments, the frustum has a stepped hole, and the stepped hole has multiple claws arranged along the circumferential direction, which engage with the groove.

[0014] In some embodiments, the socket further includes: The second sealing ring is fitted outside the socket island and is sealed to the inside of the plate end on the plug.

[0015] The beneficial effects of the technical solution provided by this invention include: This invention provides a connector including a socket, an interlocking assembly, a CPA component, and a plug. The socket has a power socket terminal at its bottom. The interlocking assembly is movably disposed within the socket and has a signal socket terminal at its bottom. The CPA component is disposed on top of the interlocking assembly. The plug is disposed at the bottom of the socket and has a power pin terminal and a signal pin terminal. When the plug is used to connect to the socket, the power pin terminal first connects to the power socket terminal, then drives the CPA component to move the interlocking assembly, and the signal pin terminal connects to the signal socket terminal, energizing the power pin terminal and the power socket terminal. When the plug is used... When separated from the socket, the CPA component is driven to move the interlock assembly. The signal pin terminal separates from the signal socket terminal first, de-energizing the power pin terminal and the power socket terminal. The power pin terminal and the power socket terminal then separate. The CPA component drives the interlock assembly to move, controlling the on / off state of the signal circuit. Utilizing the characteristic that the signal pin terminal and the signal socket terminal separate after contact, the signal circuit controls the on / off state of the power circuit. This allows the signal circuit and the power circuit to be switched on and off at different times. When the circuit is connected to or disconnected from a voltage of 48V or higher, this avoids arcing at the connector's pin terminals and socket terminals, improving the connector's reliability.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] This invention provides a connector that solves the technical problem in the related art where existing connectors generate electric arcs at the pin terminals and socket terminals when connected to or disconnected from a circuit with a voltage of 48V or higher, leading to connector damage.

[0020] Figure 1 and Figure 2 This is a connector provided in an embodiment of the present invention, comprising: a socket 1, an interlocking assembly 2, a CPA component 3, and a plug 4.

[0021] The socket 1 has a power socket terminal 11 at its bottom. The interlocking assembly 2 is movably disposed inside the socket 1 and has a signal socket terminal 21 at its bottom. The CPA component 3 is disposed on the top of the interlocking assembly 2. The plug 4 is disposed at the bottom of the socket 1 and has a power pin terminal 41 and a signal pin terminal 42. When the plug 4 is used to connect to the socket 1, the power pin terminal 41 first connects to the power socket terminal 11, and then the CPA component 3 is driven to move the interlocking assembly 2. The signal pin terminal 42 connects to the signal socket terminal 21, so that the power pin terminal 41 and the power socket terminal 11 are energized. When the plug 4 is used to separate from the socket 1, the CPA component 3 is driven to move the interlocking assembly 2. The signal pin terminal 42 and the signal socket terminal 21 first separate, so that the power pin terminal 41 and the power socket terminal 11 are de-energized, and then the power pin terminal 41 and the power socket terminal 11 are separated again.

[0022] This invention relates to a socket, an interlocking assembly, a CPA component, and a plug. The socket has a power socket terminal at its bottom. The interlocking assembly is movably disposed within the socket and has a signal socket terminal at its bottom. The CPA component is located on top of the interlocking assembly. The plug is located at the bottom of the socket and has a power pin terminal and a signal pin terminal. When the plug is used to connect to the socket, the power pin terminal first connects to the power socket terminal, then the CPA component is driven to move the interlocking assembly along the length of the socket, and the signal pin terminal connects to the signal socket terminal, energizing both the power pin terminal and the power socket terminal. When the plug is used to disconnect from the socket, the CPA component is driven to move the interlocking assembly in the opposite direction, the signal pin terminal first separates from the signal socket terminal, de-energizing both the power pin terminal and the power socket terminal. The power pin terminal then separates from the power socket terminal again, de-energizing both the power pin terminal and the power socket terminal. The interlocking assembly and the signal socket terminal are positioned at a high position. Regarding the power socket terminal, it is ensured that the power pin terminal and the power socket terminal are energized after the signal pin terminal and the signal socket terminal are connected, and de-energized after the signal pin terminal and the signal socket terminal are disconnected. Since the signal pin terminal is connected to the controller, when the signal pin terminal and the signal socket terminal are connected, the controller receives a signal to control the power pin terminal and the power socket terminal to be energized. Similarly, when the signal pin terminal and the signal socket terminal are disconnected, the controller receives a signal to control the power pin terminal and the power socket terminal to be de-energized. The CPA component drives the interlocking assembly to move to control the signal circuit on and off, and utilizes the characteristic that the signal pin terminal and the signal socket terminal separate after contact to achieve the mechanical interlocking function of the signal circuit controlling the power circuit on and off, so that the signal circuit and the power circuit are switched on and off in a time-sharing manner. When the circuit is connected to energize or disconnected at 48V or higher voltage, the pin terminals and socket terminals of the connector are prevented from generating electric arcs, thus improving the reliability of the connector.

[0023] As an optional implementation, in one embodiment of the invention, see [link to relevant documentation]. Figure 3 , Figure 4 and Figure 7As shown, the interlocking assembly 2 further includes: a square block 22 and a cylindrical rod 23. The square block 22 is vertically disposed within the socket 1, and a signal jack terminal 21 is provided at the bottom of the square block 22. The cylindrical rod 23 is disposed at the top of the square block 22 and passes through a circular hole 12 in the socket 1. A groove 231 is provided at the top of the cylindrical rod 23, and the groove 231 engages with the CPA component 3. The square block 22 and the cylindrical rod 23 are connected to form a whole, and the width of the square block 22 is greater than the diameter of the cylindrical rod 23 to prevent the square block 22 from passing through the circular hole 12. The column rod 23 passes through the circular hole 12 and can slide along the length direction of the socket 1. When the CPA component 3 is pressed along the length direction of the socket 1, the CPA component 3 drives the square block 22 and the cylindrical rod 23 to slide closer to the plug 4 until the signal pin terminal 42 is connected to the signal jack terminal 21. When the CPA component 3 is lifted along the length direction of the socket 1, the CPA component 3 drives the square block 22 and the cylindrical rod 23 to slide away from the plug 4 until the signal pin terminal 42 is disconnected from the signal jack terminal 21.

[0024] As an optional implementation, in one embodiment of the invention, see [link to relevant documentation]. Figure 7 As shown, the top of the cylindrical rod 23 is also provided with a step 232. The top of the step 232 is a chamfered structure. The chamfer removes the sharp angle of the top edge of the cylindrical rod 23, which facilitates the insertion and snapping of the top of the cylindrical rod 23 with the CPA part 3. The chamfer can also disperse stress and improve the fatigue strength of the cylindrical rod 23.

[0025] As an optional implementation, in one embodiment of the invention, see [link to relevant documentation]. Figure 3 , Figure 4 , Figure 7 As shown, the signal jack terminal 21 includes: a square hole 211, a conductive sheet 212, and a pin opening 213. The square hole 211 is disposed through the bottom of the square block 22. The conductive sheet 212 is disposed inside the square hole 211 and is used for electrical connection with the signal pin terminal 42. The pin opening 213 is disposed on the outside of the conductive sheet 212 and located at the bottom of the square block 22. The square hole 211 is used to restrict and fix the conductive sheet 212. The pin opening 213, through notches with fixed spacing and shape, enables the conductive sheet 212 to be quickly plugged and unplugged with external data cables or other devices, and can also prevent users from plugging it in backwards, avoiding damage to the equipment or causing safety hazards.

[0026] Specifically, see Figure 5 and Figure 6As shown, when the plug 4 is used to connect to the socket 1, the power pin terminal 41 is first connected to the power socket terminal 11, and then the CPA component 3 is driven to slide the interlocking assembly 2 towards the plug 4 along the length direction of the socket 1. Then, the signal pin terminal 42 passes through the pin port 213 and is electrically connected to the conductive piece 212, thereby energizing the power pin terminal 41 and the power socket terminal 11. When the CPA component 3 is driven to slide the interlocking assembly 2 away from the plug 4 along the length direction of the socket 1, the conductive piece 212 and the pin port 213 are disengaged from the signal pin terminal 42, and the signal pin terminal 42 is disconnected from the signal socket terminal 21, thereby de-energizing the power pin terminal 41 and the power socket terminal 11.

[0027] As an optional implementation, in one embodiment of the invention, see [link to relevant documentation]. Figure 7 and Figure 9 As shown, the conductive sheet 212 includes: a square box 2121 and two sets of spring contacts 2122. The square box 2121 is disposed inside the square hole 211, and the two sets of spring contacts 2122 are symmetrically disposed on both sides of the square box 2121. The two sets of spring contacts 2122 respectively engage with the signal pin terminal 42. The width of the square box 2121 matches the square hole 211, so that the square box 2121 is fixed in the middle of the square hole 211, and the two sets of spring contacts 2122... 22 is completely located inside the square hole 211, preventing the spring piece 2122 from being exposed; when the two sets of spring pieces 2122 engage with the signal pin terminal 42, they provide positive pressure, so that the spring piece 2122 and the signal pin terminal 42 are tightly fitted to form a stable electrical path. Through elastic design, it absorbs mechanical stress during vibration or impact, preventing the connection from loosening or breaking. The spring piece 2122, as a contact, achieves rapid switching through elastic deformation, and can also effectively resist wear and fatigue.

[0028] As an optional implementation, in one embodiment of the invention, see [link to relevant documentation]. Figure 7 and Figure 9 As shown, the conductive sheet 212 further includes a spring fin 2123, which is disposed at the bottom of the square box 2121. The spring fin 2123 engages with the stepped hole 2111 disposed in the square hole 211. The spring fin 2123 is used to limit the square box 2121 from shaking in the square hole 211 and further limit the two sets of spring pieces 2122 from falling out of the square hole 211.

[0029] As an optional implementation, in one embodiment of the invention, see [link to relevant documentation]. Figure 3 , Figure 4 , Figure 7As shown, the interlocking assembly 2 further includes a first sealing ring 24, which is sleeved on the tail of the cylindrical rod 23 and sealed to the circular hole 12. The first sealing ring 24 is sleeved on the outside of the cylindrical rod 23. When the CPA component 3 drives the interlocking assembly 2 to slide along the length direction of the socket 1, the cylindrical rod 23 can slide within the first sealing ring 24 along the length direction of the socket 1. The first sealing ring 24 is used to prevent moisture and dust from entering the connector, ensuring the connector's waterproofness and sealing performance.

[0030] As an optional implementation, in one embodiment of the invention, see [link to relevant documentation]. Figure 3 , Figure 4 and Figure 8 As shown, the CPA component 3 includes: a locking seat 31, a boss 32, and a crossbeam 33. The locking seat 31 is horizontally disposed on one side of the socket 1. The boss 32 is vertically disposed below the locking seat 31. The top of the boss 32 abuts against the lug crossbeam 13 on the socket 1 and the plate end bracket 43 on the plug 4. The plate end bracket 43 is used to press the boss 32 away from the lug crossbeam 13. The crossbeam 33 is disposed on one side of the locking seat 31. A frustum 331 is provided on the crossbeam 33. The frustum 331 engages with the groove 231.

[0031] Specifically, the top of the protrusion 32 has a V-shaped structure. When the plug 4 is not connected to the socket 1, see [reference needed]. Figure 3 As shown, the top of the protrusion 32 abuts against the lug crossbeam 13 on the socket 1. The lug crossbeam 13 forms a limit at the front end of the protrusion 32, preventing the locking seat 31 and the protrusion 32 from being pressed when the plug 4 is not connected to the socket 1, and further preventing the frustum 331 from causing the square block 22 and the cylindrical rod 23 to slide closer to the plug 4; when the plug 4 is used to connect to the socket 1, see Figure 4As shown, the top of the protrusion 32 abuts against the plate end bracket 43 on the plug 4. The plate end bracket 43 presses the protrusion 32 away from the nose beam 13. When the locking seat 31 is pressed along the length direction of the socket 1, the protrusion 32 slides towards the plug 4 along the length direction of the socket 1. Furthermore, the truncated cone 331 drives the square block 22 and the cylindrical rod 23 to slide towards the plug 4 until the signal pin terminal 42 and the signal jack terminal are connected. 21 is connected, so that the power pin terminal 41 is energized with the power socket terminal 11; when the locking seat 31 is lifted along the length direction of the socket 1, the boss 32 slides away from the plug 4 along the length direction of the socket 1, and further the truncated cone 331 drives the square block 22 and the cylindrical rod 23 to slide away from the plug 4 until the signal pin terminal 42 is disconnected from the signal socket terminal 21, so that the power pin terminal 41 is de-energized from the power socket terminal 11.

[0032] As an optional implementation, in one embodiment of the invention, see [link to relevant documentation]. Figure 7 and Figure 8 As shown, the frustum 331 has a stepped hole 3311 inside, and multiple claws 3312 are arranged along the circumferential direction inside the stepped hole 3311. The multiple claws 3312 engage with the groove 231. There are four claws 3312, and the four conical claws 3312 are symmetrically distributed in the stepped hole 3311. The top end of the cylindrical rod 23 passes through the stepped hole 3311. The four conical claws 3312 engage with the groove 231 and stably clamp the top end of the cylindrical rod 23, which can effectively prevent the cylindrical rod 23 from shifting or falling off when the frustum 331 drives the cylindrical rod 23 to slide.

[0033] As an optional implementation, in one embodiment of the invention, see [link to relevant documentation]. Figure 3 and Figure 4 As shown, the socket 1 further includes a second sealing ring 14, which is sleeved on the outside of the socket 1. The second sealing ring 14 is sealed to the inside of the plate end 44 on the plug 4. When the plug 4 is connected to the socket 1, the plate end 44 on the plug 4 is located inside the socket 1 and is sealed to the second sealing ring 14. The second sealing ring 14 is used to prevent moisture and dust from entering the connector, further ensuring the waterproofness and sealing of the connector.
