Description

Technical Field

[0001] Cross - reference to Related Applications This application claims the benefit of Chinese Patent Application No. CN202210225027.5 filed on March 9, 2022 and Chinese Patent Application No. CN202220496338.0 filed on March 9, 2022 with the State Intellectual Property Office of China, the entire disclosures of which are 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, a connector at the end of a cable usually 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 mating terminals of a 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 a connector mates with a 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 a connector and the mating terminals of a 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 mate 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 Initiative] [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 a mounting port, a connection assembly mounted in the mounting port of the housing and adapted to fasten the terminals of the connector to the mating terminals of a mating connector, and a safety cover slidably mounted on the housing. The connection assembly has a first operating part, which is exposed from the housing so that the connection assembly can be fastened or loosened by operating the first operating part. 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 to a safety position.

[0008] According to an exemplary embodiment of the present invention, when the connection assembly is fastened during the process of mating one connector with the other connector, the first operating part is positioned so as not to interfere with the safety cover, in order to allow the safety cover to move between the initial position and the safety position.

[0009] 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.

[0010] 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.

[0011] According to another exemplary embodiment of the present invention, an operating hole is formed in the safety cover, and when the safety cover is in its initial position, the second operating part is exposed from the safety cover through the operating hole.

[0012] According to another exemplary embodiment of the present invention, a guide slot extending in a first direction is formed on one of the outer wall surface of the housing and the inner wall surface of the safety cover, and a guide rib extending in the first direction is formed on the other, the guide rib being fixed in the guide slot and movable along the guide slot in the first direction to guide the safety cover to move between an initial position and a safe position relative to the housing.

[0013] According to another exemplary embodiment of the present invention, guide slots are formed on the outer wall surface of the housing, guide ribs are formed on the inner wall surface of the side wall of the safety cover, the guide slots have a guide surface extending in a first direction, and the guide ribs slide in contact with the guide surface to guide the guide ribs to move in the first direction.

[0014] According to another exemplary embodiment of the present invention, a limiting portion is formed on the inner wall surface of the top wall of the safety cover, and as the safety cover moves from an initial position to a safe position, the limiting portion abuts against a first operating portion to limit the safety cover to the safe position.

[0015] According to another exemplary embodiment of the present invention, the connector further comprises a cable, one end of which is inserted into the housing in a first direction and electrically connected to the terminals, and an end cover, which is fitted around one end of the housing and used to secure the cable to the housing.

[0016] According to another exemplary embodiment of the present invention, a cable port is formed at one end of the housing to allow insertion of a cable in a first direction, an installation port is formed at the top of the other end of the housing to allow insertion of a connection assembly in a second direction perpendicular to the first direction, and a mating port is formed at the bottom of the other end of the housing to allow a connector to mate with a mating connector in a second direction.

[0017] According to another exemplary embodiment of the present invention, each of the safety cover and the end cover has a front end and a rear end opposite to each other in a first direction, and when the safety cover moves from the safety position to the initial position, the front end surface of the end cover abuts against the rear end surface of the safety cover to restrict the safety cover to the initial position.

[0018] According to another exemplary embodiment of the present invention, the housing comprises at least two housing units and a connecting portion connected between two adjacent housing units. Mounting holes are formed in the connecting portion, and mechanical connecting members are installed in the mounting holes in the connecting portion. The connector comprises at least two terminals, each located in at least two housing units for electrical connection with at least two mating terminals; at least two connection assemblies, each installed in at least two housing units for connecting the at least two terminals to at least two mating terminals; at least two cables, each inserted into the at least two housing units and electrically connected to at least two terminals; and at least two end covers, each externally mounted on one end of the at least two housing units for securing the at least two cables to the at least two housing units.

[0019] According to another exemplary embodiment of the present invention, the safety cover is a integrally molded part.

[0020] According to another exemplary embodiment of the present invention, the connector further comprises terminals arranged in the housing for electrical connection with the mating terminals of the mating connector.

[0021] According to another exemplary embodiment of the present invention, the safety cover comprises a top wall having an operating hole formed therein, and a pair of side walls, each connected to the top wall. When the safety cover is in its initial position, the first operating part is located on the outside of the safety cover.

[0022] According to another exemplary embodiment of the present invention, an elastic cantilever is formed on the safety cover and a limiting projection is formed on the housing, and when the housing is not fitted with the mating housing and the safety cover is in its initial position, the elastic cantilever is positioned to interfere with the limiting projection in order to prevent the safety cover from moving from its initial position to the safe position.

[0023] According to another exemplary embodiment of the present invention, when the housing is fitted with the mating housing and the safety cover is in the initial position, the elastic cantilever is pushed to a position where it does not interfere with the limiting protrusion by the unlocking portion in the mating housing so that the movement of the safety cover is not hindered by the limiting protrusion.

[0024] According to another exemplary embodiment of the present invention, when the housing is fitted with the mating housing and the safety cover has moved to the safe position, the free end of the elastic cantilever abuts against the stopping portion in the mating housing so as to limit the safety cover to the safe position.

[0025] 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 fit with the connector. The mating connector includes a mating housing suitable for fitting with the housing of the connector and mating terminals provided in the mating housing for electrical connection with the terminals of the connector.

[0026] According to an exemplary embodiment of the present invention, the mating connector further includes a mating connection assembly in which a threaded hole is formed. The connection assembly includes a threaded connection member connected to the threaded hole. A threaded connection hole is formed in the mating housing, and the mechanical connection member of the connector has a threaded connection portion connected to the threaded connection hole.

[0027] According to another aspect of the present invention, a connector is provided. The connector includes a housing, a mechanical connection member installed in the housing and suitable for threaded connection of the housing to the mating housing of the mating connector, and a safety cover slidably mounted on the housing. The mechanical connection member has an operation portion, and the operation portion is exposed from the housing so that the mechanical connection member can be fastened or loosened by operating the operation portion. In the process of fitting the connector with the mating connector, when the mechanical connection member is not fastened, in order to prevent the safety cover from moving from the initial position to the safe position, the operation part is at a position where it interferes with the safety cover. In the process of fitting the connector with the mating connector, when the mechanical connection member is fastened, in order to enable the safety cover to move from the initial position to the safe position, the operation part is at a position where it does not interfere with the safety cover. When the safety cover is in the initial position, in order to enable the mechanical connection member to be fastened or loosened by operating the operation part, the operation part is not covered by the safety cover. When the safety cover is in the safe position, in order to prevent the mechanical connection member from being loosened by operating the operation part, the operation part is covered by the safety cover.

[0028] In the above exemplary embodiment according to the present invention, not only can the safety cover reliably prevent the fastened connection assembly from accidentally loosening, but it can also easily determine whether the connection assembly is fastened, thereby improving the safety of using the connector.

[0029] In addition, in the above exemplary embodiment according to the present invention, since the high-voltage interlock is linked to the safety cover, it can be ensured 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.

[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.

[0073] 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.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] 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.

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.

[0083] 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.

[0084] 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.

[0085] 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).

[0086] 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.

[0087] 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.

[0088] 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.

[0089] 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.
