Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and in particular to an anti-condensation socket, an anti-condensation connector and an electrical appliance box. Background Art

[0002] Currently, detachable connections on the three-electric system (battery pack, motor, and electronic control) and high-voltage distribution box enclosures of new energy electric vehicles typically involve individually mounting finished connector sockets on their respective enclosure panels, then plugging in separate plug harnesses to complete the connection. Existing connectors lack condensation protection. This means that when hot air inside the enclosure rapidly cools within the connector, condensation forms inside the connector, potentially causing a sudden drop in insulation resistance and even serious insulation failure. Summary of the Invention

[0003] The object of the present invention is to provide an anti-condensation socket, an anti-condensation connector and an electrical appliance box, so as to solve the problem that existing connectors do not have the anti-condensation function.

[0004] The technical solution of the present invention to solve the above technical problems is as follows:

[0005] A condensation-proof socket comprises: a socket housing, a socket front cover, a pin mounting plate and a socket tail cover; the pin mounting plate comprises a head portion and a tail portion; the head portion extends into the socket housing and is respectively connected to the socket housing and the socket front cover; a boss is provided between the head portion and the tail portion, the boss contacts the socket housing and is sealed to the socket housing via a first sealing ring; the tail portion is connected to the socket tail cover and is sealed to the socket tail cover via a first sealing gasket; a wire hole is provided on the first sealing gasket.

[0006] The first sealing ring of the present invention can prevent hot air in the box from entering the interior of the socket from the connection position between the pin mounting plate and the socket shell, and the first sealing gasket can prevent hot air in the box from entering the interior of the socket from the connection position between the pin mounting plate and the socket tail cover. When the cable passes through the wire hole, it can also be sealed with the first sealing gasket to prevent hot air from entering the interior of the socket along with the cable, thereby preventing the hot air from being rapidly cooled inside the socket and generating condensation, so that the socket has an anti-condensation function.

[0007] The boss on the pin mounting plate can contact the socket housing. After the head of the pin mounting plate is connected to the socket housing, the pin mounting plate can be effectively limited and the pin mounting plate and the socket housing can be tightly connected.

[0008] Furthermore, the above-mentioned socket housing includes a connecting tube and a connecting plate arranged at one end of the connecting tube; the connecting plate is provided with a through hole, and the inner edge of the connecting plate extends to the interior of the connecting tube; the head passes through the through hole of the connecting plate and is connected to the inner edge, and the boss contacts the outer wall of the connecting plate.

[0009] Furthermore, the connecting tube and the connecting plate are integrally formed.

[0010] The connecting tube and the connecting plate of the present invention are integrally formed, which can reduce the entry points of hot air.

[0011] Furthermore, a first wedge-shaped clamping block is provided on the outer side of the head, and the first clamping block is in contact with the inner edge.

[0012] One side of the connecting plate of the present invention contacts the boss, and the other side contacts the first clamping block. Through the clamping action of the first clamping block and the boss, the pin mounting plate and the socket housing can be firmly connected. Moreover, the pin mounting plate and the socket housing can be connected by only plugging.

[0013] Furthermore, a card slot is provided on the outer side of the head; and a second card block matching the card slot is provided on the inner side wall of the front cover of the socket.

[0014] When the socket front cover of the present invention is connected to the pin mounting plate, the second clamping block is deformed by extrusion and enters the clamping groove, so that the socket front cover and the pin mounting plate are clamped.

[0015] Furthermore, the pin mounting plate is internally provided with pin terminals and high-voltage interlocking pin terminals.

[0016] A condensation-proof connector comprises the above-mentioned condensation-proof socket and an condensation-proof plug that cooperates with the condensation-proof socket; the condensation-proof plug comprises a plug front cover, a jack mounting plate and a plug tail cover that are connected in sequence; the jack mounting plate is sealed with the plug front cover and the plug tail cover via a second sealing ring and a second sealing gasket respectively, and the second sealing gasket is provided with a wire hole; the jack mounting plate cooperates with the pin mounting plate.

[0017] The second sealing ring and second sealing gasket of the present invention can prevent hot air from entering the interior of the anti-condensation plug. When the cable passes through the cable hole, it can also form a seal between the second sealing gasket and prevent hot air from entering the plug along with the cable. This can prevent the hot air from rapidly cooling inside the plug and causing condensation, thus giving the plug an anti-condensation function. When the anti-condensation plug is matched with the anti-condensation socket, a connector with anti-condensation function is formed.

[0018] Furthermore, a jack terminal and a high-voltage interlocking jack terminal are provided inside the jack mounting plate, and the jack terminal and the high-voltage interlocking jack terminal are matched with the pin terminal and the high-voltage interlocking pin terminal respectively.

[0019] Furthermore, the above-mentioned anti-condensation plug also includes a U-shaped handle, the two ends of the handle are respectively rotatably connected to the jack mounting plate, and a first rack-shaped locking block is provided on the inner side of the handle; the socket housing is provided with a second rack-shaped locking block that cooperates with the first locking block.

[0020] The U-shaped handle of the present invention is used for locking the anti-condensation plug when it is connected to the anti-condensation socket. During the connection, the handle is rotated so that the handle is perpendicular to the anti-condensation plug. After the anti-condensation plug is connected to the anti-condensation socket, the anti-condensation plug is rotated so that the first locking block cooperates with the second locking block to achieve locking between the anti-condensation plug and the anti-condensation socket.

[0021] An electrical appliance box comprises the above-mentioned anti-condensation socket and a box body; the box body and the socket shell are integrally formed, and the box body is a battery pack box body, a motor box body, an electric control box body or a high-voltage distribution box box body.

[0022] The electrical box of the present invention adopts a method of integrally forming the socket shell and the box body, which reduces the entry points of hot air and solves the sealing problem. At the same time, the socket shell and the box body are integrally formed, avoiding the need to connect and install the socket and the box body, and other components of the socket can be conveniently and quickly connected to the socket shell, which has high production efficiency and correspondingly reduces costs.

[0023] The present invention has the following beneficial effects:

[0024] (1) The anti-condensation socket, anti-condensation plug, connector containing the anti-condensation socket and the anti-condensation plug, and electrical appliance box containing the anti-condensation socket of the present invention all have an anti-condensation function, which can prevent hot air from entering the interior of the socket or plug, thereby preventing the hot air from being rapidly cooled inside the plug and causing condensation, and avoiding the problem of sudden resistance drop and even insulation failure.
