Abstract
Description
Technical Field
[0001] This application relates to the field of electrical connection device technology, and in particular to a connector and connector assembly. Background Technology
[0002] Connector assemblies are devices used to enable electrical connections between different devices. The application of connector assemblies improves the efficiency of electrical connections between different devices and is currently widely used in the automotive, communications, consumer electronics, data processing, and industrial machinery industries.
[0003] A connector assembly typically includes two connectors that enable electrical connection. One connector serves as a socket, fixed to a device, panel, or circuit board. The other connector serves as a plug, connecting to one end of a cable.
[0004] The connector has internal power terminals. When the two connectors are mated, they form a locking engagement through a locking structure, creating a stable conductive contact between the power terminals. At this point, one connector can transfer load current to the other.
[0005] However, when load current is being transferred between the two connectors, the two connectors are in a free-separating state when the locking mechanism unlocks, and a large current still flows through the power terminals of the two connectors before separation. At the instant the power terminals separate, an arc discharge occurs between them due to the inductance in the circuit. This arc discharge may cause the power terminals to melt or vaporize, resulting in pits or burrs on the surface, potentially leading to poor contact during subsequent use. Furthermore, the arc discharge may also cause the insulation material around the power terminals to carbonize and decompose, resulting in a decrease in insulation effectiveness. Utility Model Content

[0018] In one embodiment, in a projection plane perpendicular to the insertion direction, the distance between the projection area of the first limiting part and the projection area of the second limiting part is not greater than the thickness of the front end of the fastener.

For example, they can refer to fixed connections, detachable connections, integral connections, mechanical connections, electrical connections, direct connections, indirect connections via an intermediate medium, or internal connections between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0033] The technical solutions provided by the embodiments of this application are described below with reference to the accompanying drawings.
[0034] Combination Figure 1 and Figure 2 As shown, this application provides a connector assembly 100. The connector assembly 100 can be used to achieve electrical connection between different devices. Specifically, the connector assembly 100 can be used to transmit electrical power and electronic signals.
[0035] Combination Figure 2 As shown, the connector assembly 100 includes two mating connectors. In some embodiments, the two mating connectors are a first connector 20 and a second connector 30. In some embodiments, the first connector 20 is used for electrical connection to one device, and the second connector 30 is used for electrical connection to another different device. Once the first connector 20 and the second connector 30 are mechanically and electrically connected, electrical energy or electronic signals can be transmitted between the two devices. In other embodiments, the first connector 20 and the second connector 30 may also be used in the same device to transmit electrical energy and electronic signals between two different modules of that device.
[0036] In some embodiments, the first connector 20 and the second connector 30 are mechanically locked in their relative positions by a snap-fit connection. In some embodiments, after the first connector 20 and the second connector 30 are snap-fitted, their ports remain in a plugged-in state.
[0037] In some embodiments, one of the first connector 20 and the second connector 30 may serve as a socket, fixed to a device, panel, or circuit board. In one embodiment, one of the first connector 20 and the second connector 30 may be fixed to a cabinet panel of the device. The other of the first connector 20 and the second connector 30 serves as a plug and is connected to another device via an electrical cable.
[0038] In some implementations, combined Figure 2 and Figure 3 As shown, the first connector 20 includes a first housing 21, a first signal terminal 26, and a first power terminal 27. The first signal terminal 26 is positioned and accommodated within the first housing 21. The first power terminal 27 is positioned and accommodated within the first housing 21.
[0039] In some implementations, combined Figure 2 and Figure 3 As shown, the second connector 30 includes a second housing 31, a latching member 32 movably connected to the second housing 31, a second signal terminal 33 positioned and accommodated in the second housing 31, and a second power terminal 34 positioned and accommodated in the second housing 31. The latching member 32 has a locked position and an unlocked position relative to the second housing 31. Understandably, the latching member 32 is in the locked position when no unlocking operation is performed, and in the unlocked position when an unlocking operation is performed.
[0040] Specifically, in combination Figure 6 As shown, the first connector 20 corresponds to a predetermined insertion direction F1. A portion of the second connector 30 can be accommodated into the first connector 20 along the insertion direction F1. Exemplarily, the second housing 31, the latching member 32, the second signal terminal 33, or the second power terminal 34 can be accommodated into the first connector 20 along the insertion direction F1.
[0041] Combination Figure 6 and Figure 7 As shown, this application also provides a connector, as the first connector 20 described above. In this connector, a first housing 21 is provided with a mating end 201 and a wire harness end 202 facing each other along the insertion direction F1. The first housing 21 is provided with a first limiting part 22 and a second limiting part 23, and a gap 24 is reserved between the first limiting part 22 and the second limiting part 23 for the fastener 32 to pass through. The first limiting part 22 has a first stop surface 221, and the second limiting part 23 has a second stop surface 231. The first stop surface 221 is disposed downstream of the second stop surface 231 along the insertion direction F1. The orientations of the first stop surface 221 and the second stop surface 231 correspond to the insertion direction F1. The first stop surface 221 is used to stop the fastener 32 in the locked position. The second stop surface 231 is used to stop the fastener 32 in the unlocked position.
[0042] The connector of this application, combined with Figure 3 As shown, the first connector 20 is briefly described below. After the latching member 32 of the second connector 30 passes through the gap 24 between the first limiting part 22 and the second limiting part 23 along the insertion direction F1, the latching member 32 returns to the locked position. The first stop surface 221 forms a stop engagement with the latching member 32 in the locked position, inhibiting the reverse movement of the latching member 32 along the insertion direction F1. At this time, a conductive contact is formed between the first signal terminal 26 and the second signal terminal 33, and a conductive contact is formed between the first power terminal 27 and the second power terminal 34. The first connector 20 and the second connector 30 can transmit load current through the power terminals.
[0043] When it is necessary to separate the first connector 20 and the second connector 30, during the unlocking operation of the latching member 32, the latching member 32, in the unlocked position, deviates from the first stop surface 221. The latching member 32 can then move relative to the first housing 21 in the opposite direction of the insertion direction F1 until it forms a stop engagement with the second stop surface 231. At this time, the first power terminal 27 and the second power terminal 34 maintain conductive contact, while the first signal terminal 26 and the second signal terminal 33 are electrically isolated. The separation between the first signal terminal 26 and the second signal terminal 33 generates feedback to the external control module, which uses corresponding switching devices to stop the load current based on this feedback.
[0044] Combination Figure 4 As shown, when the latching member 32 and the second stop surface 231 form a stop engagement, the latching member 32 returns to the locked position by ending the unlocking operation. Since the first stop surface 221 is located downstream of the second stop surface 231 along the insertion direction F1, the latching member 32 will no longer be stopped by the first stop surface 221 after returning to the locked position. The latching member 32 can continue to move relative to the first housing 21 in the opposite direction of the insertion direction F1 until the first power terminal 27 and the second power terminal 34 are completely separated. Since the load current has stopped when the first power terminal 27 and the second power terminal 34 are separated, no arc discharge will occur when the first power terminal 27 and the second power terminal 34 are separated, thereby avoiding melting or vaporization of the first power terminal 27 or the second power terminal 34, and preventing carbonization and decomposition of the insulating material around the first power terminal 27 or the second power terminal 34.
[0045] Understandably, the first stop surface 221 can cooperate with the latching member 32 in the locked position to keep the first connector 20 and the second connector 30 in a fully mated state. In the fully mated state, a conductive contact is formed between the first signal terminal 26 and the second signal terminal 33, and a conductive contact is formed between the first power terminal 27 and the second power terminal 34. The cooperation between the second stop surface 231 and the latching member 32 in the unlocked position creates a pause during the separation process of the first connector 20 and the second connector 30. This pause provides the necessary response time for the control module and switching devices, allowing them to stop the load current in time before the first power terminal 27 and the second power terminal 34 are completely separated, thus avoiding arc discharge.
[0046] Understandably, the second connector 30 has a first position and a second position relative to the first connector 20.
[0047] Combination Figure 3 As shown, in the first position, the first connector 20 and the second connector 30 are connected in a plug-in relationship, and the first stop surface 221 and the latching member 32 in the locked position form a stop engagement. Conductive contacts are formed between the first signal terminal 26 and the second signal terminal 33, and between the first power terminal 27 and the second power terminal 34, respectively.
[0048] Combination Figure 4 As shown, in the second position, the first connector 20 and the second connector 30 are connected, the second stop surface 231 forms a stop engagement with the latch 32 in the unlocked position, the first power terminal 27 and the second power terminal 34 respectively form conductive contact, and the first signal terminal 26 and the second signal terminal 33 form electrical isolation.
[0049] When a conductive contact is formed between the first signal terminal 26 and the second signal terminal 33, for example, the first signal terminal 26 is inserted into the second signal terminal 33, or the second signal terminal 33 is inserted into the first signal terminal 26.
[0050] When a conductive contact is formed between the first power terminal 27 and the second power terminal 34, for example, the first power terminal 27 is inserted into the second power terminal 34, or the second power terminal 34 is inserted into the first power terminal 27.
[0051] For example, the orientation of the first stop surface 221 and the orientation of the second stop surface 231 are approximately in the same direction as the insertion direction F1. For example, the orientation of the first stop surface 221 or the orientation of the second stop surface 231 may have a certain angle relative to the insertion direction F1 to prevent the latching member 32 from detaching from the first stop surface 221 or the second stop surface 231.
[0052] Optionally, combined Figure 3 As shown, during the unlocking operation, the user presses the latch 32 toward the interior of the second housing 31. Exemplarily, the latch 32 has a force-applying portion 326 for the user's finger to press. Understandably, the locked and unlocked positions are radially opposite to each other along the second housing 31.
[0053] In some other embodiments, during the unlocking operation, the user may rotate the latch 32 along the tangential direction of the outer periphery of the second housing 31. Understandably, the locked and unlocked positions are arranged opposite each other along an arc.
[0054] In some implementations, combined Figure 3 As shown, the latching member 32 is rotatably connected to the second housing 31. Optionally, the second connector 30 includes a shaft 35. The shaft 35 is respectively inserted into the second housing 31 and the latching member 32.
[0055] In some implementations, combined Figure 3 As shown, the second connector 30 includes an elastic element 36 that abuts against the second housing 31 between the locking member 32 and the retaining member 32. When the retaining member 32 is not pressed, the elastic force of the elastic element 36 keeps the retaining member 32 in a locked position. When the retaining member 32 is pressed, causing it to be in an unlocked position, the compression of the elastic element 36 increases. Exemplarily, the retaining member 32 has a front end 321 for insertion into the first housing 21. The elastic element 36 is disposed between the front end 321 of the retaining member 32 and the shaft 35.
[0056] In some implementations, combined Figure 5 As shown, the second connector 30 also includes a second insulating member 37 positioned and connected to the second housing 31. Second power terminals 34 and second signal terminals 33 are respectively inserted into the second insulating member 37. Exemplarily, the second insulating member 37 has a plurality of second power terminals 34 and a plurality of second signal terminals 33 inserted into it.
[0057] In some implementations, combined Figure 6 As shown, the first connector 20 further includes a first insulating member 28 positioned and connected to the first housing 21. A first signal terminal 26 and a first power terminal 27 are respectively inserted into the first insulating member 28. Exemplarily, the first insulating member 28 has a plurality of first power terminals 27 and a plurality of first signal terminals 26 inserted into it.
[0058] In some implementations, combined Figure 6 and Figure 7As shown, the first housing 21 is provided with a guide groove 25. The guide groove 25 extends to the mating end 201 of the first housing 21. For the two opposing inner wall surfaces 251 of the guide groove 25, the first limiting part 22 protrudes relative to one of the inner wall surfaces 251, and the second limiting part 23 protrudes relative to the other inner wall surface 251. Understandably, when the first connector 20 and the second connector 30 are mated, the guide groove 25 is used for the insertion of the latching member 32. The movement of the latching member 32 along the insertion direction F1 is guided by the guide groove 25. Since the first limiting part 22 and the second limiting part 23 are provided in the guide groove 25, when the latching member 32 moves in the opposite direction along the insertion direction F1, it is beneficial to ensure that the latching member 32 can accurately form a stop engagement with the first limiting part 22 or the second limiting part 23, and to avoid the latching member 32 failing to form a stop engagement with the second limiting part 23 due to deviation or misalignment.
[0059] In some implementations, combined Figure 6 As shown, the first limiting part 22 is disposed on the side of the second limiting part 23 opposite to the first power terminal 27. Understandably, when the locked and unlocked positions are radially opposite each other along the second housing 31, when the latching member 32 is subjected to a pressing unlocking operation, the front end 321 of the latching member 32 moves towards the first power terminal 27. Since the second limiting part 23 is closer to the first power terminal 27 relative to the first limiting part 22, the latching member 32 in the unlocked position can form a stop engagement with the second stop surface 231.
[0060] In some implementations, combined Figure 6 and Figure 7 As shown, the first limiting part 22 is provided with a first inclined surface 222. Along the insertion direction F1, the first inclined surface 222 is inclined toward the direction of the first power terminal 27. Understandably, when the locked position and the unlocked position are radially opposite each other along the second housing 31, when the first connector 20 and the second connector 30 need to be mated, the front end 321 of the latching member 32 must pass through the gap 24 between the first limiting part 22 and the second limiting part 23. The first inclined surface 222 contacts the front end 321 of the latching member 32. Guided by the first inclined surface 222, the latching member 32 gradually moves toward the unlocked position, allowing the latching member 32 to smoothly bypass the obstruction of the first limiting part 22 and reach the position corresponding to the first stop surface 221.
[0061] In some implementations, combined Figure 6 and Figure 7As shown, the second limiting part 23 is provided with a second inclined surface 232. Along the insertion direction F1, the second inclined surface 232 is inclined in the direction away from the first power terminal 27. Understandably, when the locked position and the unlocked position are radially opposite each other along the second housing 31, when the first connector 20 and the second connector 30 need to be mated, the front end 321 of the latching member 32 needs to pass through the second limiting part 23 before passing through the gap 24 between the first limiting part 22 and the second limiting part 23. When the second inclined surface 232 contacts the front end 321 of the latching member 32, the second inclined surface 232 guides the front end 321 of the latching member 32, allowing the front end 321 of the latching member 32 to bypass the second limiting part 23 and smoothly reach the gap 24 between the first limiting part 22 and the second limiting part 23, thus avoiding the second limiting part 23 from causing jamming of the front end 321 of the latching member 32.
[0062] In some implementations, combined Figure 6 As shown, in the projection plane perpendicular to the insertion direction F1, along the relative direction F4 between the projection areas of the first limiting part 22 and the second limiting part 23, the width W2 of the second stop surface 231 along the relative direction F4 is smaller than the width W1 of the first stop surface 221 along the relative direction F4. Understandably, the first limiting part 22 has a larger protrusion height relative to the second limiting part 23, so that in the fully mated state between the first connector 20 and the second connector 30, the latching member 32 requires a larger range of motion to move away from the first stop surface 221, thus more reliably preventing the latching member 32 from accidentally detaching from the first stop surface 221. During the separation process of the first connector 20 and the second connector 30, because the width W2 of the second stop surface 231 is relatively small, the latching member 32 only needs a small range of motion to deviate from the second stop surface 231. Furthermore, the relatively small width W1 of the second stop surface 231 also reduces the difficulty of inserting the front end 321 of the latching member 32 into the guide groove 25.
[0063] In some other embodiments, depending on the structural layout of the first housing 21, the width W2 of the second stop surface 231 along the opposite direction F4 may also be greater than or equal to the width W1 of the first stop surface 221 along the opposite direction F4.
[0064] Understandably, during the unlocking operation, if the pressing depth of the latch 32 is insufficient, the latch 32 may not reach the position where it can abut against the second stop surface 231 during the separation of the first connector 20 and the second connector 30. This may cause the second connector 30 to complete the separation process directly without any pause.
[0065] In some implementations, combined Figure 7 and Figure 8As shown, in the projection plane perpendicular to the insertion direction F1, the distance D1 between the projection area of the first limiting part 22 and the projection area of the second limiting part 23 is not greater than the thickness of the front end 321 of the fastening member 32. Understandably, when the first connector 20 and the second connector 30 are mated, the fastening member 32 begins to insert into the gap 24 with its front end 321. When separating the first connector 20 and the second connector 30, since the distance D1 between the projection area of the first limiting part 22 and the projection area of the second limiting part 23 is not greater than the thickness of the front end 321 of the fastening member 32, the front end 321 of the fastening member 32 cannot directly pass through the gap 24 between the first limiting part 22 and the second limiting part 23 along a path parallel to the insertion direction F1. As long as the front end 321 of the fastening member 32 can deviate from the first stop surface 221, the fastening member 32 can abut against the second stop surface 231.
[0066] In some implementations, combined Figure 3 and Figure 8 As shown, the latching member 32 has a through groove 322. When the first stop surface 221 forms a stop engagement with the latching member 32 in the locked position, the first limiting part 22 is inserted into the through groove 322. When the second stop surface 231 forms a stop engagement with the latching member 32 in the unlocked position, the second limiting part 23 is inserted into the through groove 322. Understandably, when the first limiting part 22 is inserted into the through groove 322, the first stop surface 221 and a portion of the sidewall of the through groove 322 are in a relative relationship, and the latching member 32 is suppressed from moving in the reverse direction F1 by abutting. When the second limiting part 23 is inserted into the through groove 322, the second stop surface 231 and a portion of the sidewall of the through groove 322 are in a relative relationship, and the latching member 32 is suppressed from moving in the reverse direction F1 by abutting.
[0067] In other embodiments, grooves may be provided on opposite sides of the fastener 32 so that the first limiting part 22 or the second limiting part 23 can be partially accommodated in the fastener 32, while the first limiting part 22 or the second limiting part 23 abuts against the partial wall surface of the fastener 32.
[0068] In some implementations, combined Figure 7 and Figure 8As shown, the latching member 32 includes a main latching portion 323, side portions 324, and a locking portion 325. The main latching portion 323 is movably connected to the second housing 31. The two side portions 324 are respectively connected to the main latching portion 323. The locking portion 325 is horizontal and connected between the two side portions 324. The main latching portion 323, the locking portion 325, and the two side portions 324 define a through groove 322. The width of the locking portion 325 is not greater than the distance D2 between the first stop surface 221 and the second stop surface 231 along the insertion direction F1. Understandably, when the first connector 20 and the second connector 30 are mated, the main latching portion 323 needs to pass through the gap 24 between the first limiting portion 22 and the second limiting portion 23. Since the width of the locking portion 325 is not greater than the distance D2 between the first stop surface 221 and the second stop surface 231 along the insertion direction F1, the main latching portion 323 is prevented from being blocked when passing through the gap 24. Combination Figure 8 As shown, the width direction of the locking part 325 is parallel to arrow F2.
[0069] Understandably, when the first limiting part 22 is inserted into the through groove 322, the locking part 325 is disposed opposite to the first stop surface 221 along the insertion direction F1. When the second limiting part 23 is inserted into the through groove 322, the locking part 325 is disposed opposite to the second stop surface 231 along the insertion direction F1.
[0070] For example, in a projection plane perpendicular to the insertion direction F1, the distance D1 between the projection area of the first limiting part 22 and the projection area of the second limiting part 23 is not greater than the thickness of the locking part 325. (Combined) Figure 8 As shown, the thickness direction of the locking part 325 is parallel to arrow F3.
[0071] For example, the shaft 35 is inserted into the main buckle 323 and the second housing 31.
[0072] Understandably, the locking part 325 forms the front end 321 of the latching member 32.
[0073] The above embodiments are merely preferred embodiments of this application and are not intended to limit the scope of this application. Any modifications and improvements made by those skilled in the art to the technical solutions of this application without departing from the spirit of this application should fall within the protection scope defined by the claims of this application.
