[0001] Cross - reference to related applications This application claims the benefit of Chinese Patent Application No. CN202210224214.1 filed on March 9, 2022 and Chinese Patent Application No. CN202220498838.8 filed on March 9, 2022 with the China National Intellectual Property Administration, the entire disclosure of which is incorporated herein by reference.

[0002] The present invention relates to a connector and a connector assembly including the connector.

Background Art

[0003] In the prior art, the connector at the end of a cable generally includes a housing, terminals, a connection assembly and a cable. The terminals are arranged in the housing, and the cable extends into the housing and is electrically connected to the terminals. A connection assembly used to fasten the terminals to the mating terminals of the mating connector so that the terminals are electrically connected to the mating terminals of the mating connector is installed in the housing.

[0004] In the prior art, when the connector is mated with the mating connector, there is a lack of a safety protection device for determining whether the connection assembly is fastened and preventing the fastened connection assembly from accidentally loosening. Therefore, the safety of using the connector is reduced.

[0005] In addition, in the prior art, in order to detect the connection state between the terminals of the connector and the mating terminals of the mating connector, it is also necessary to provide a high - voltage interlock (also called a detection connector) and a mating high - voltage interlock (also called a mating detection connector) on the connector and the mating connector respectively. However, since the existing high - voltage interlock is fixed to the housing of the connector, there is a possibility that the high - voltage interlock may be mated with the mating high - voltage interlock before the terminals of the connector are electrically connected to the mating terminals of the mating connector, which also reduces the safety of using the connector. [Overview of the project] [Problems that the invention aims to solve]

[0006] This invention was made to overcome or mitigate at least one of the above-mentioned difficulties. [Means for solving the problem]

[0007] According to one aspect of the present invention, a connector is provided. The connector comprises a housing having slots and mounting ports formed therein; a connection assembly installed in the mounting ports of the housing and adapted to fasten the terminals of the connector to the mating terminals of a mating connector; a safety cover movably mounted on the housing, the safety cover being movable between an initial position in which the connection assembly is not covered by the safety cover and a safety position in which the connection assembly is covered by the safety cover; and a high-voltage interlock movably mounted in the slot, the high-voltage interlock being movable between a connection position in which the high-voltage interlock engages with a mating high-voltage interlock of a mating connector and a disconnection position in which the high-voltage interlock is disconnected from the mating high-voltage interlock. During the process of mating one connector with the other, if the connection assembly is not fastened, the connection assembly is positioned to interfere with the safety cover to prevent the safety cover from moving from its initial position to the safe position. The safety cover is slidably connected to the high-voltage interlock so that the safety cover and the high-voltage interlock are linked in such a relationship that when the safety cover moves to the initial position, the high-voltage interlock moves to the disconnected position, and when the safety cover moves to the safe position, the high-voltage interlock moves to the connected position.

[0008] According to an exemplary embodiment of the present invention, the high-voltage interlock comprises an insulator and two detection terminals fixed to the insulator and used to electrically connect to the positive and negative terminals of a high-voltage interlock circuit, respectively. When the high-voltage interlock moves to the connected position, the two detection terminals of the high-voltage interlock are electrically connected to the opposite detection terminal of the other high-voltage interlock, turning on the high-voltage interlock circuit. When the high-voltage interlock moves to the disconnected position, the two detection terminals are disconnected from the opposite detection terminal, cutting off the high-voltage interlock circuit.

[0009] According to another exemplary embodiment of the present invention, the safety cover is configured to move between an initial position and a safety position in a first direction, and the high-voltage interlock is configured to move between a connected position and a disconnected position in a second direction perpendicular to the first direction.

[0010] According to another exemplary embodiment of the present invention, a guide slot extending in a first direction is formed on one of the inner wall surface of the safety cover and the outer wall surface of the housing, and a guide rib extending in the first direction is formed on the other, the guide slot slidably engaging with the guide rib to guide the safety cover to move between an initial position and a safe position relative to the housing in the first direction.

[0011] According to another exemplary embodiment of the present invention, the slot in the housing extends in a second direction, and the insulator for the high-voltage interlock comprises a first portion extending in the second direction, the first portion of the insulator slidably fitted with the slot in the housing to guide the high-voltage interlock to move between a connected position and a disconnected position relative to the housing in the second direction.

[0012] According to another exemplary embodiment of the present invention, the insulator for the high-voltage interlock further comprises a second portion connected to a first portion and located outside the housing, the detection terminals being fixed to the first portion of the insulator and the second portion of the insulator being slidably connected to a safety cover.

[0013] According to another exemplary embodiment of the present invention, a pair of support walls are formed on the inner wall surface of a safety cover, a portion of a second part of an insulator is positioned in the gap between the pair of support walls, a chute is formed on each side of the second part of the insulator facing the support walls, a protrusion is formed on the support wall and slidably connected to the chute, the chute comprises a main portion extending a predetermined length in a direction inclined with respect to a first direction in order to convert the movement of the safety cover in a first direction into the movement of a high-voltage interlock in a second direction.

[0014] According to another exemplary embodiment of the present invention, the chute further includes a first end and a second end, each connected to two ends of the main body of the chute, the first and second ends extending along a first direction, the projection moving toward the first end of the chute when the safety cover moves to an initial position, and the projection moving toward the second end of the chute when the safety cover moves to a safe position.

[0015] According to another exemplary embodiment of the present invention, the high-voltage interlock further includes a sealing ring that is fitted over a first portion of the insulator and used to seal the gap between the first portion of the insulator and a slot in the housing.

[0016] According to another exemplary embodiment of the present invention, the connection assembly has a first operating part that is exposed from the housing so that the connection assembly can be fastened or loosened by operating the first operating part, and in the process of mating the connector with the mating connector, if the connection assembly is not fastened, the first operating part is positioned to interfere with the safety cover to prevent the safety cover from moving from an initial position to a safe position, if the safety cover is in the initial position, the first operating part is not covered by the safety cover so that the connection assembly can be fastened or loosened by operating the first operating part, and if the safety cover is in the safe position, the first operating part is covered by the safety cover to prevent the connection assembly from loosening by operating the first operating part.

[0017] According to another exemplary embodiment of the present invention, in the process of mating one connector with the other connector, if the connection assembly is fastened, the first operating part is positioned so as not to interfere with the safety cover, in order to allow the safety cover to move from the initial position to the safe position.

[0018] According to another exemplary embodiment of the present invention, the connector further comprises a mechanical connecting member that is installed in the housing and is suitable for screw connection with a mating housing for fastening the housing to the mating housing of the mating connector. The mechanical connecting member has a second operating part, which is exposed from the housing so that the mechanical connecting member can be tightened or loosened by operating the second operating part. In the process of mating the connector with the mating connector, if the mechanical connecting member is not tightened, the second operating part is positioned to interfere with the safety cover to prevent the safety cover from moving from the initial position to the safe position. If the safety cover is in the initial position, the second operating part is not covered by the safety cover so that the mechanical connecting member can be tightened or loosened by operating the second operating part. If the safety cover is in the safe position, the second operating part is covered by the safety cover to prevent the mechanical connecting member from loosening by operating the second operating part.

[0019] According to another exemplary embodiment of the present invention, in the process of mating one connector with the other connector, when the connecting assembly and mechanical connecting members are fastened, the first and second operating parts are positioned so as not to interfere with the safety cover, in order to allow the safety cover to move from the initial position to the safe position.

[0020] According to another exemplary embodiment of the present invention, the safety cover comprises a top wall in which an operating hole is formed, and a pair of side walls connected to both sides of the top wall, respectively. When the safety cover is in its initial position, a first operating part is located on the outside of the safety cover, and a second operating part is exposed from the safety cover through the operating hole.

[0021] According to another exemplary embodiment of the present invention, a restricting portion is formed on an inner wall surface of a top wall of a safety cover, and when the safety cover moves from an initial position to a safety position, the restricting portion abuts against a first operating portion so as to restrict the safety cover in the safety position.

[0022] According to another exemplary embodiment of the present invention, the connector further includes terminals disposed in a housing for electrical connection with mating terminals of a mating connector.

[0023] According to another exemplary embodiment of the present invention, the connector further includes a cable having one end inserted into the housing in a first direction and electrically connected to the terminals, and an end cover externally mounted on one end of the housing and used to fix the cable to the housing.

[0024] According to another exemplary embodiment of the present invention, a cable port enabling insertion of the cable in a first direction is formed at one end of the housing, a mounting port is formed at the top of the other end of the housing to enable insertion of the connection assembly in a second direction perpendicular to the first direction, and a fitting port is formed at the bottom of the other end of the housing to enable the connector to fit with a mating connector in the second direction.

[0025] According to another exemplary embodiment of the present invention, an elastic cantilever is formed on the safety cover, a restricting protrusion is formed on the housing, and when the housing is not fitted with a mating housing and the safety cover is in an initial position, the elastic cantilever is in a position interfering with the restricting protrusion to prevent the safety cover from moving from the initial position to the safety position.

[0026] According to another exemplary embodiment of the present invention, when the housing is fitted with a mating housing and the safety cover is in an initial position, the elastic cantilever is pushed by a unlocking portion of the mating housing to a position where it does not interfere with the restricting protrusion so that the movement of the safety cover is not obstructed by the restricting protrusion.

[0027] According to another aspect of the present invention, a connector assembly is provided. The connector assembly includes the above-described connector and a mating connector adapted to mate with the connector. The mating connector includes a mating housing suitable for mating with the housing of the connector, mating terminals disposed in the mating housing for electrical connection with the terminals of the connector, and a mating high-voltage interlock disposed in the mating housing for mating with the high-voltage interlock of the connector.

[0028] In the above-described exemplary embodiment according to the present invention, since the high-voltage interlock is linked to the safety cover, it is possible to ensure that the high-voltage interlock is always disconnected from the mating high-voltage interlock before the terminals of the connector are electrically connected to the mating terminals of the mating connector, thereby improving the safety of using the connector.

[0029] In addition, in the above-described exemplary embodiment according to the present invention, the safety cover can not only reliably prevent the fastened connection assembly from accidentally loosening, but also easily determine whether the connection assembly is fastened, thereby improving the safety of using the connector.

[0030] The above and other features of the present invention will become more apparent by describing its exemplary embodiments in detail with reference to the accompanying drawings.

[0059] As shown in Figures 1 to 10, in the exemplary embodiment, a cable port 1014 is formed at one end of the housing 10, allowing the cable 14 to be inserted in a first direction. A mounting port 1011 is formed at the top of the other end of the housing 10 to allow the connection assembly 11 to be inserted in a second direction perpendicular to the first direction. A mating port is formed at the bottom of the other end of the housing 10 to allow the connector 1 to mate with the mating connector 2 in a second direction.

[0060] As shown in Figures 1 to 10, in the exemplary embodiment, each of the safety cover 100 and the end cover 15 has a front end and a rear end that are opposite to each other in a first direction. When the safety cover 100 moves from the safety position to the initial position, the front end surface of the end cover 15 abuts against the rear end surface of the safety cover 100 to restrict the safety cover 100 to the initial position.

[0061] As shown in Figures 1 to 10, in the exemplary embodiment, the housing 10 includes at least two housing units and a connecting portion 10a. The connecting portion 10a connects two adjacent housing units of the housing 10. A mounting hole is formed in the connecting portion 10a, and a mechanical connecting member 12 is installed in the mounting hole of the connecting portion 10a.

[0062] As shown in Figures 1 to 10, in an exemplary embodiment, the connector 1 includes at least two terminals 13, at least two connection assemblies 11, at least two cables 14, and at least two end covers 15.

[0063] However, the present invention is not limited to the exemplary embodiments. For example, connector 1 may include one terminal 13, one connection assembly 11, one cable 14, and one end cover 15.

[0064] As shown in Figures 1 to 10, in the exemplary embodiment, the safety cover 100 is a single-piece molded component. For example, the safety cover 100 may be integrally molded.

[0065] Figure 11 is an explanatory diagram of connector 1 according to an exemplary embodiment of the present invention, in which the connection assembly 11 and mechanical connection member 12 are in the fastening position and the safety cover 100 is in the initial position. Figure 12 is an explanatory perspective view of mating connector 2 according to an exemplary embodiment of the present invention.

[0066] As shown in Figures 1 to 12, in the exemplary embodiment, the elastic cantilever 102b is formed on the safety cover 100 and the limiting projection 10d is formed on the housing 10. As shown in Figure 11, when the housing 10 is not fitted with the mating housing 20 and the safety cover 100 is in its initial position, the elastic cantilever 102b is positioned to interfere with the limiting projection 10d in order to prevent the safety cover 100 from moving from its initial position to the safe position.

[0067] As shown in Figures 1 to 12, in the exemplary embodiment, when the housing 10 is fitted with the mating housing 20 and the safety cover 100 is in its initial position, the elastic cantilever 102b is pushed by the unlocking portion 20d in the mating housing 20 to a position where it does not interfere with the restricting projection 10d, so that the movement of the safety cover 100 is not obstructed by the restricting projection 10d.

[0068] As shown in Figures 1 to 12, in the exemplary embodiment, when the housing 10 is fitted with the mating housing 20 and the safety cover 100 is moved to the safe position, the free end of the elastic cantilever 102b abuts against the stopper portion 20b of the mating housing 20 to restrict the safety cover 100 to the safe position.

[0069] As shown in Figures 1 to 12, in the exemplary embodiment, a screw hole 210 is formed in the mating terminal 21, or a screw hole 210 is formed in the mating connection assembly 22 which is assembled with the mating terminal 21, and the connection assembly 11 includes a screw connection member 110 which is connected to the screw hole 210.

[0072] As shown in Figures 1 to 16, in exemplary embodiments of the present invention, a connector 1 is also disclosed. The connector 1 includes a housing 10, terminals 13, a connection assembly 11, a safety cover 100, and a high-voltage interlock 16. The housing 10 has a slot 1016 and a mounting port 1011 formed therein. The terminals 13 are positioned in the housing 10. The connection assembly 11 is mounted in the mounting port 1011 of the housing 10 and is suitable for fastening the terminals 13 to the mating terminals 21 of a mating connector 2. The safety cover 100 is movably mounted in the housing 10 and is movable between an initial position in which the connection assembly 11 is not covered by the safety cover 100 and a safe position in which the connection assembly 11 is covered by the safety cover 100. The high-voltage interlock 16 is movably installed in slot 1016 and is movable between a connection position in which the high-voltage interlock 16 engages with the mating high-voltage interlock 26 of the mating connector 2 and a disconnection position in which the high-voltage interlock 16 is disconnected from the mating high-voltage interlock 26.

[0073] As shown in Figures 1 to 16, in the exemplary embodiment, when connector 1 is mated with mating connector 2 and the connection assembly 11 is not fastened, the connection assembly 11 is in a position to interfere with the safety cover 100 in order to prevent the safety cover 100 from moving from its initial position to a safe position.

[0074] Figure 19 shows a cross-sectional view of the high-voltage interlock 16 and safety cover 100 of connector 1 and the mating high-voltage interlock 26 of mating connector 2 according to an exemplary embodiment of the present invention, where the safety cover 100 is in the safety position and the high-voltage interlock 16 is in the connection position. Figure 20 shows an explanatory diagram of the high-voltage interlock 16 and safety cover 100 of connector 1 and the mating high-voltage interlock 26 of mating connector 2 according to an exemplary embodiment of the present invention, where the safety cover 100 is in the safety position and the high-voltage interlock 16 is in the connection position. Figure 21 shows a cross-sectional view of the high-voltage interlock 16 and safety cover 100 of connector 1 and the mating high-voltage interlock 26 of mating connector 2 according to an exemplary embodiment of the present invention, where the safety cover 100 is in the safety position and the high-voltage interlock 16 is in the connection position.

[0075] As shown in Figures 1 to 16 and Figures 19 to 21, in the exemplary embodiment, the safety cover 100 and the high-voltage interlock 16 are connected so that they slide together in a linked manner, namely, when the safety cover 100 moves to the initial position, the high-voltage interlock 16 moves to the disconnected position, and when the safety cover 100 moves to the safe position, the high-voltage interlock 16 moves to the connected position.

[0076] Figure 17 shows an explanatory assembly diagram of the high-voltage interlock 16 and safety cover 100 of connector 1 according to an exemplary embodiment of the present invention, with the safety cover 100 in its initial position. Figure 18 shows an explanatory diagram of the safety cover 100 of connector 1 according to an exemplary embodiment of the present invention, viewed from below, showing the structure connected to the high-voltage interlock 16.

[0077] As shown in Figures 1 to 21, in the exemplary embodiment, the high-voltage interlock 16 includes an insulator 161 and two detection terminals 163. The two detection terminals 163 are fixed to the insulator 161 for electrical connection to the positive and negative terminals of a high-voltage interlock circuit (not shown). When the high-voltage interlock 16 moves to the connected position, the two detection terminals 163 of the high-voltage interlock 16 are electrically connected to the mating detection terminals 263 of the mating high-voltage interlock 26, turning on the high-voltage interlock circuit. When the high-voltage interlock 16 moves to the disconnected position, the two detection terminals 163 are disconnected from the mating detection terminals 263, cutting off the high-voltage interlock circuit.

[0078] As shown in Figures 1 to 21, in the exemplary embodiment, when connector 1 is mated with mating connector 2 and the connection assembly 11 is not fastened, the connection assembly 11 is in a position that interferes with the safety cover 100 so that the safety cover 100 cannot be moved from the initial position to the safe position. Therefore, when the connection assembly 11 is not fastened, the high-voltage interlock 16 is always in the disconnected position. The high-voltage interlock 16 can only be moved to the connected position when the connection assembly 11 is fastened.

[0079] As shown in Figures 1 to 21, in the exemplary embodiment, when connector 1 is mated with the mating connector 2, the high-voltage interlock circuit is turned on only after the high-voltage terminals (terminals 13 and 21) are electrically connected, and when connector 1 and the mating connector 2 are disconnected, the high-voltage interlock circuit is cut off before the high-voltage terminals (terminals 13 and 21) are disconnected. This prevents hot-wire insertion and removal of the high-voltage terminals (terminals 13 and 21), improving the safety of the connector during use.

[0080] As shown in Figures 1 to 21, in the exemplary embodiment, the safety cover 100 is configured to move between an initial position and a safety position in a first direction (horizontal direction in Figures 1 to 21). The high-voltage interlock 16 is configured to move between a connected position and a disconnected position in a second direction (vertical direction in Figures 1 to 21) perpendicular to the first direction.

[0081] As shown in Figures 1 to 21, in the exemplary embodiment, a guide slot 10b extending in a first direction is formed on one of the inner wall surface of the safety cover 100 and the outer wall surface of the housing 10, and a guide rib 102a extending in the first direction is formed on the other. The guide slot 10b slidably engages with the guide rib 102a to guide the safety cover 100 to move between an initial position and a safe position in the first direction relative to the housing 10.

[0082] As shown in Figures 1 to 21, in the exemplary embodiment, the slot 1016 in the housing 10 extends in a second direction, and the insulator 160 of the high-voltage interlock 16 includes a first portion 161 that extends in the second direction. The first portion 161 of the insulator 160 slidably fits with the slot 1016 of the housing 10 to guide the high-voltage interlock 16 to move between a connected position and a disconnected position relative to the housing 10 in a second direction.

[0083] As shown in Figures 1 to 21, in the exemplary embodiment, the insulator 160 of the high-voltage interlock 16 further includes a second portion 162 connected to a first portion 161, the second portion 162 being located outside the housing 10. The detection terminal 163 is fixed to the first portion 161 of the insulator 160, and the second portion 162 of the insulator 160 is slidably connected to the safety cover 100.

[0084] As shown in Figures 1 to 21, in the exemplary embodiment, a pair of support walls 103 are formed on the inner wall surface of the top wall 101 of the safety cover 100, and a portion of the second portion 162 of the insulator 160 is positioned in the gap between the pair of support walls 103. A chute 1620 is formed on each side of the second portion 162 of the insulator 160. Each of the pair of support walls 103 has a projection 103a that is slidably connected to the chute 1620. The chute 1620 includes a main portion 1623 that extends for a predetermined length in a direction inclined with respect to the first direction in order to convert the movement of the safety cover 100 in the first direction (horizontal direction in Figures 1 to 21) to the movement of the high-voltage interlock 16 in the second direction (vertical direction in Figures 1 to 21).

[0085] As shown in Figures 1 to 21, in the exemplary embodiment, the chute 1620 further includes a first end 1621 and a second end 1622, which are connected to the two ends of the main portion 1623 of the chute 1620, respectively, and the first end 1621 and the second end 1622 extend in a first direction. When the safety cover 100 moves to the initial position, the projection 103a moves to the first end 1621 of the chute 1620. When the safety cover 100 moves to the safe position, the projection 103a moves to the second end 1622 of the chute 1620.

[0086] As shown in Figures 1 to 21, in the exemplary embodiment, the high-voltage interlock 16 further includes a seal ring 164. The seal ring 164 is mounted on the first portion 161 of the insulator 160 to seal the gap between the first portion 161 of the insulator 160 and the slot 1016 of the housing 10.

[0087] As shown in Figures 1 to 21, in the exemplary embodiment, the mating connector 2 includes an inner housing 200 made of insulating material, and the mating high-voltage interlock 26 is fixedly mounted in the inner housing 200. The mating high-voltage interlock 26 includes an insulator 260 and a mating detection terminal 263 located on the insulator 260. When the high-voltage interlock 16 is mated with the mating high-voltage interlock 26, the mating detection terminal 263 is bridged between two detection terminals 163 to connect two detection terminals 163.

[0088] As shown in Figures 1 to 21, exemplary embodiments of the present invention also disclose a connector assembly including a connector 1 and a mating connector 2 suitable for mating with connector 1. The mating connector 2 includes a mating housing 20, mating terminals 21 and a mating high-voltage interlock 26. The mating housing 20 is suitable for mating with the housing 10 of connector 1. The mating terminals 21 are located in the mating housing 20 for electrical connection with terminals 13 of connector 1.
