Description

Technical Field

[0001] The utility model relates to the technical field of connector design, in particular to an MSD connector and an electrical system. Background Art

[0002] A manual maintenance switch (MSD) is a high-voltage connector with a fuse, which generally includes a plug assembly and a socket assembly that plug into each other. When the power system needs to be repaired, in order to ensure the safety of the operator, the power supply of the high-voltage system can be disconnected by separating the socket assembly of the MSD connector from the plug assembly of the MSD connector. It can achieve electrical isolation of the high-voltage system and also play a role in short-circuit protection.

[0003] At present, the MSD connector is generally installed on the box of an energy storage device such as a battery, and at least two conductive parts on the MSD connector are inside the battery box. Since one conductive part in the MSD connector needs to be connected to an external conductive part inside the battery box, and the other conductive part needs to be connected to an external conductive part outside the battery box, when the operator needs to connect the conductive part to the external conductive part outside the battery box, it is necessary to connect the conductive part on the MSD connector through a connecting wire, and then lead the wire from the battery box to the external conductive part outside the battery box. In addition, the battery box needs to be pre-designed with a through hole for the wire to pass through. From the above connection process, it can be seen that the operator needs to perform complex operations to achieve the connection between the conductive part in the MSD connector and the external conductive part outside the battery box, which brings great inconvenience to the operator and greatly affects the operator's work efficiency.

[0004] Therefore, finding a technical solution that can solve the above technical problems has become an important topic studied by technical personnel in this field. Utility Model Content

DETAILED DESCRIPTION

[0037] The embodiment of the utility model discloses an MSD connector and a power system, which are used to solve the technical problem that a plug component and a socket component in an existing MSD connector are easily separated, thereby causing power loss or circuit breakage during use of the MSD connector.

[0038] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0039] See also Figures 1 to 9 In an embodiment of the utility model, an MSD connector is provided, comprising a socket assembly 1 and a plug assembly 2 plugged and matched with the socket assembly 1;

[0040] The plug assembly 2 includes a plug housing 201 and a first conductive member 206 disposed in the plug housing 201;

[0041] The socket assembly 1 includes a base 109, a socket housing 101 provided on a first side surface of the base 109 and matched with the plug housing 201, a second conductive member 110 and a third conductive member 111 provided in the socket housing 101, one end of the second conductive member 110 and the third conductive member 111 are used to be connected to the first conductive member 206 respectively, so as to realize electrical connection between the socket assembly 2 and the socket assembly 1;

[0042] One end of the second conductive member 110 and the third conductive member 111 away from the first conductive member 206 is exposed at the first side surface of the base 109 and the side away from the first side surface, respectively, so as to be connected to two external conductive members, respectively.

[0043] In this embodiment, when one end of the second conductive member 110 and the third conductive member 111 of the MSD connector are respectively connected to the first conductive member 206, the electrical connection between the socket assembly 1 and the plug assembly 2 can be realized, so that the MSD connector can work normally. In addition, since the ends of the second conductive member 110 and the third conductive member 111 away from the first conductive member 206 are exposed on the first side surface of the base 109 and the side away from the first side surface, respectively, the second conductive member 110 and the third conductive member 111 are respectively connected to two external conductive members. When the MSD connector is installed on the box of an energy storage device such as a battery, the third conductive member 111 is located on the inner side of the battery box and can be electrically connected to the external conductive member in the battery box, and the second conductive member 110 is located on the outer side of the battery box and can be electrically connected to the external conductive member outside the battery box. Through the above design, the operator can directly connect the second conductive member 110 located outside the battery box with the external conductive member outside the battery box, and the operator does not need any connection wire wiring operation, which greatly simplifies the operator's operation process and effectively improves the operator's work efficiency. Furthermore, compared to the prior art which requires the connection of wires and external conductive parts, in the present application, the second conductive part 110 and the third conductive part 111 are integrated into the MSD connector, and the second conductive part 110 and the third conductive part 111 can be directly bolted to the external conductive part, further simplifying the operation process of the operator and improving work efficiency.

[0044] Further, in the present embodiment, the second conductive member 110 specifically includes a U-shaped connecting section 1101 and a first section 1102 and a second section 1103 disposed at both ends of the connecting section 1101, wherein the first section 1102 is disposed in the socket housing 101 for pluggable connection with the first conductive member 206, the connecting section 1101 and the first section 1102 are bent to be accommodated in the base 109, the second section 1103 and the connecting section 1101 are bent to protrude from a first side surface of the base 109, and the second section 1103 is bent at one end away from the connecting section 1101 and is provided with a platform section 1104 parallel to the first side surface, and the platform section 1104 is used to be bolted to an external conductive member;

[0045] The third conductive member 111 in this embodiment includes a third section 1111 and a fourth section 1112 which are bent and connected. The third section 1111 is arranged in the socket housing 101 for pluggable connection with the first conductive member 206. The fourth section 1112 is bent and arranged at one end of the third section 1111 away from the first conductive member 206 and exposed from the side of the base 109 away from the first side surface. The fourth section 1112 is used for bolt connection with another external conductive member.

[0046] It should be noted that the first conductive member 206, the second conductive member 110 and the third conductive member 111 in this embodiment are all copper sheets or other metal sheets that can conduct electricity, and the first section 1102 and the third section 1111 can be respectively provided with claws to be detachably connected with the first conductive member 206, and the claws have an opening facing the first conductive member 206 to facilitate connection with the first conductive member 206. It should be noted that the specific structure of the first conductive member 206, the second conductive member 110 and the third conductive member 111 is only one of the structural forms, and it can be designed in different shapes according to actual connection needs, and this embodiment does not impose specific restrictions on this.

[0047] Furthermore, the socket assembly in this embodiment also includes a mounting seat 114 that passes through the base 109 and protrudes from the first side surface, the second section 1103 and the platform section 1104 are accommodated in the mounting seat 114, and the opposite side walls of the mounting seat 114 are provided with penetrating grooves 115 to place external conductive parts, and the mounting seat 114 is also provided with a flip top cover 103 to cover the groove 115.

[0048] It should be noted that, through the design of the flip cover, the platform section 1104 can be effectively covered to achieve effective protection of the platform section 1104. Specifically, the first section 1102 is accommodated in the socket housing 101, the connecting section 1101 is accommodated in the base 109, and the second section 1103 and the platform section 1104 are accommodated in the mounting seat 1104, thereby providing comprehensive protection for the second conductive member 110 to avoid the risk caused by the exposure of the second conductive member 110. The flip cover 103 can be flipped, which is conducive to the electrical connection between the platform section 1104 and the external conductive member, and improves the installation convenience of the operator.

[0049] Furthermore, the plug assembly 2 in this embodiment includes a rotating handle 202 rotatably connected to the plug housing 201, and the rotating handle 202 is provided with limited arc grooves 204 on opposite sides, and the plug housing 201 is provided with lifting grooves 203 extending along the height direction of the plug housing 201 on opposite sides, and the rotating handle 202 is movably provided with a locking rod 205 at one end away from the plug housing 201;

[0050] The socket housing 101 is provided with limit sliders 102 on both sides, and each limit slider 102 passes through its corresponding lifting slot 203 and then slides into the corresponding limit arc slot 204. The top surface of the flip top cover 103 is provided with a locking through hole 106 that is locked with the locking rod 205.

[0051] After the plug assembly 2 is plugged into the socket assembly 1, the rotating handle 202 is driven to rotate from the vertical direction to the horizontal direction to abut against the mounting seat 114, so that the plug assembly 2 is connected to the socket assembly 1, and the locking rod 205 can be driven to be inserted into the locking through hole 106 to limit the rotation of the rotating handle 202.

[0052] It should be noted that when the plug assembly 2 is plugged into the socket assembly 1, the rotating handle 202 is in a vertical state, and the limiting slider 102 on the socket housing 101 passes through the lifting slide groove 203 and is slidably connected with the limiting arc groove 204. When the operator operates the rotating handle 202 to rotate clockwise or counterclockwise in a preset first direction until the rotating handle 202 is in a horizontal state, the limiting slider 102 moves to the end of the limiting arc groove 204. At this time, the plug assembly 2 and the socket assembly 1 are plugged into and matched. Subsequently, the operator can complete the limiting of the rotating handle 202 by inserting the locking rod 205 into the locking through hole 106, thereby ensuring that the plug assembly 2 and the socket assembly 1 will not be separated, and ensuring that the plug assembly 2 and the socket assembly 1 are locked.

[0053] In this embodiment, the locking and disengagement of the plug assembly 2 and the socket assembly 1 are controlled by the cooperation of the limiting arc groove 204 on the plug handle and the limiting slider 102 on the socket shell 101, and when the plug assembly 2 and the socket assembly 1 are plugged in, the locking rod 205 on the rotating handle 202 can be locked and matched with the locking through hole 106 on the flip cover 103, thereby limiting the rotation of the rotating handle 202, effectively preventing the rotating handle 202 from rotating due to external force, thereby causing the plug assembly 2 and the socket assembly 1 to be disengaged, and effectively preventing the MSD from losing power or breaking the circuit during use. When the rotating handle 202 is locked to the flip cover 103, the height of the flip cover 103 can be used to compensate for the locking height, and there is no need to rotate the rotating handle 202 too much, thereby improving the locking stability and firmness.

[0054] Furthermore, since the flip cover 103 may rotate due to external force, in order to overcome the above problem, a locking assembly is provided between the flip cover and the mounting seat 114 in this embodiment, and the locking assembly includes a first lock body 112 connected to the flip cover and a second lock body 108 connected to the mounting seat 114. The first lock body 112 and the second lock body 108 are snap-fitted to achieve a detachable connection between the flip cover and the mounting seat 114. The limited locking of the flip cover 103 further limits the rotation of the rotating handle 202, thereby improving the locking stability.

[0055] Specifically, the locking assembly in this embodiment further comprises a lifting slot 104 formed on one side of the flip top cover 103 for accommodating the first lock body 112 and the second lock body 108, one end of the first lock body 112 is exposed from the lifting slot 104 and is provided with a lock tongue 105, and the other end extends into the lifting slot 104 and is provided with a pressing protrusion 113, and the second lock body 108 is formed on the side of the mounting seat 114 and forms an interference fit with the pressing protrusion 113;

[0056] It should be noted that when the flip cover 103 covers the groove 115, the lock tongue 105 is pressed so that the pressing protrusion 113 and the second lock body 108 interfere with each other to limit the rotation of the flip cover 103;

[0057] When the flip cover 103 needs to be flipped over to expose the groove 115 , the locking tongue 105 is pushed to elastically deform the first lock body 112 , and the locking tongue 105 is pulled out to drive the pressing protrusion 113 to separate from the second lock body 108 .

[0058] Furthermore, in this embodiment, a through hole is set at one end of the second conductive member 110 away from the first conductive member 206 to connect to an external conductive member through a locking screw, and a through hole is set at one end of the third conductive member 111 away from the first conductive member 206 to connect to another external conductive member through a locking screw, and the two locking screws pass through the through holes in opposite directions.

[0059] It should be noted that, through the above design, it is convenient for the operator to quickly connect the second conductive member 110 and the external conductive member, and it is convenient for the operator to quickly connect the third conductive member 111 and another external conductive member.

[0060] Furthermore, the socket assembly 1 in this embodiment also includes a supporting base plate 107, which is engaged with the side of the base 109 away from the first side surface, and a through mounting hole 117 is opened on the supporting base plate 107, and the mounting hole 117 corresponds to the fourth section 1112 to expose the fourth section 1112; a protruding limiting column 116 is also provided on the supporting base plate 107, and the limiting column 116 passes through the mounting seat 114 and is supported on the platform section 1104 and the second section 1103.

[0061] It should be noted that the support bottom plate 107 in this embodiment is snap-fitted to the side of the base 109 away from the first side surface so as to achieve quick assembly and disassembly between the support bottom plate 107 and the base 109 .

[0062] The design of the mounting hole 117 can further facilitate the conductive connection between the fourth section 1112 in the third conductive member 111 and an external conductive member.

[0063] The design of the above-mentioned limiting column 116 can realize the limiting effect on the second section 1103 of the second conductive member 110, thereby preventing the second conductive member 110 from being horizontally displaced by external force. At the same time, the design of the above-mentioned limiting column 116 can realize the limiting effect on the platform section 1104, thereby ensuring the stable connection between the platform section 1104 and the external conductive member.

[0064] refer to Figure 8When the second conductive member 110 and the external conductive member need to be installed, the locking tongue 105 is pushed to elastically deform the first lock body 113, and the locking tongue 105 is pulled out, so that the pressing protrusion 113 and the second lock body 108 are separated, and the flip cover 103 can be flipped to expose the second section 1103. At this time, the locking screw penetrates the through hole on the second section 1103 from bottom to top, and the protrusion of the locking screw is pressed against the bottom surface of the second section. The external conductive member is placed on the second section 1103 from the opposite direction of the two grooves 115, and the through hole of the external conductive member is aligned with the locking screw so that the locking screw passes through the through hole of the external conductive member. After that, a nut is installed from the end of the locking screw away from the protrusion to fix the external conductive member to the second section 1103, thereby achieving electrical connection. After that, the flip cover 103 can be flipped, covered with the groove 115, and locked by the locking assembly to protect the second section 1103 and the external conductive member. When the third conductive component 111 and another external conductive component need to be installed, since the fourth section is exposed from the base 109, the locking screw passes through the fourth section 1112 from top to bottom, and the raised portion of the locking screw abuts against the top of the fourth section 1112, directly fitting the fourth section 1112 to the external conductive component. At this time, the locking screw penetrates the through hole of the external conductive component, and a nut is installed at the end of the locking screw away from the raised portion to fix the external conductive component to the fourth section 1112, thereby achieving electrical connection, improving overall operational convenience, and improving work efficiency.

[0065] Furthermore, a waterproof rubber ring is provided at the position where the plug housing 201 in this embodiment contacts the socket housing 101;

[0066] It should be noted that, since both the plug housing 201 and the socket housing 101 are made of hard materials, there will always be a gap between the two when they are plugged together, and external water vapor has the opportunity to enter the MSD connector through the gap, thereby causing metal parts to rust. Therefore, by adding a waterproof rubber ring at the contact position between the plug housing 201 and the socket housing 101, the above situation can be effectively avoided, greatly increasing the working stability of the MSD connector.

[0067] Furthermore, in order to prevent an operator from getting an electric shock when operating the MSD connector, the plug housing 201 and the socket housing 101 in this embodiment are both made of insulating plastic.

[0068] See also Figures 1 to 9 In an embodiment of the utility model, a power consumption system is provided, including the above-mentioned MSD connector.

[0069] It should be noted that the above-mentioned power system may be an energy storage device. When the energy storage device needs to be repaired, in order to ensure the safety of the operator, the power supply of the power system is disconnected by unplugging the plug assembly 2 in the MSD connector from the socket assembly 1.

[0070] The above is a detailed introduction to an MSD connector and a power system provided by the present invention. For a person skilled in the art, according to the idea of ​​the embodiments of the present invention, there may be changes in the specific implementation method and the scope of application. In summary, the content of this specification should not be understood as a limitation on the present invention.
