Description
Technical Field
[0001] The utility model relates to the technical field of vehicle connectors, in particular to a self-cooling automobile connector. Background Art
[0002] Automotive connectors are a type of component that electronic engineers often come into contact with. Its function is very simple: to build a bridge of communication between blocked or isolated circuits in a circuit, so that current can flow and the circuit can achieve its intended function. The form and structure of automotive connectors are ever-changing, and they are mainly composed of four basic structural components, namely: contact, housing (depending on the type), insulator, and accessories. In the industry, they are usually called sheaths, connectors, and plastic shells.
[0003] Due to process problems, the connection of existing automotive connectors adopts a structure in which the shell includes a metal connector, and due to the need for waterproofing, a fully sealed structure is also used.
[0004] The above-mentioned prior art solutions have the following defects: the fully sealed structure has poor heat dissipation. When the internal connection lines are in poor contact or the resistance here increases sharply due to long-term use, a large amount of internal heat will accumulate, posing a risk of burning. Utility Model Content
[0005] The utility model aims to provide a self-cooling automobile connector.
[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0007] It includes a first connector and a second connector, the first connector is provided with a connection groove, the second connector is arranged to be engaged with the connection groove, a plurality of heat dissipation fins are fixedly arranged on the outer wall of the first connector, a heat spreader wrapping the second connector is buried inside the shell of the first connector, and the heat dissipation fins are fixedly connected to the heat spreader.
[0008] By adopting the above technical solution, the heat spreader buried inside the first connector can effectively absorb the heat generated at the connection between the first connector and the second connector and transfer it to the remaining parts with lower temperatures, thereby avoiding the situation where local heat concentration burns the connectors. At the same time, the external heat dissipation fins can transfer the absorbed heat to the outside air by heat exchange. In summary, the structure of the heat spreader combined with the heat dissipation fins can effectively balance the heat of different parts inside the connector and at the same time reduce the overall operating temperature of the connector to avoid heat accumulation and burning.
[0009] Furthermore, a plurality of heat pipes are arranged through the heat dissipation fins, the heat pipes are arranged in parallel and spaced apart from each other, the heat pipes surround the first connector in a ring shape, and the heat pipes are hollow and contain easily evaporable liquid.
[0010] By adopting the above technical solution, the setting of the heat pipe can further disperse and conduct the heat on the cooling fins, avoiding the situation where local heat concentration on the cooling fins affects the overall heat dissipation power. The evaporated liquid inside can vaporize when absorbing heat, and the steam will liquefy and release heat when it moves irregularly to the lower temperature area of the heat pipe, so that the heat pipe has excellent thermal conductivity.
[0011] Furthermore, a fixed locking column is extended from the outer wall of the first connector, a sealing convex cap is fixedly provided at one end of the locking column close to the first connector, a convex surface of the sealing convex cap is connected to the first connector, a plurality of elastic locking ridges parallel to each other are arranged around the locking column, and a cross-shaped anti-rotation ridge is fixedly provided at the end of the locking column.
[0012] By adopting the above technical solution, the setting of the locking column can conveniently fix the first connector and the second connector on the vehicle body. It only needs to open a locking groove that cooperates with the locking column on the vehicle body. The setting of the elastic locking ridge can effectively ensure the firmness of the connection between the locking column and the vehicle body. At the same time, the elastic locking ridge can be deformed and separated by pulling hard, and it has good repeated disassembly performance. The anti-rotation ridge will be embedded in the vehicle body when engaged to limit the locking column and prevent it from rotating and affecting the firmness of the connection.
[0013] Furthermore, an elastic waterproof sleeve surrounding the connection groove opening is fixedly provided on the outer wall of the first connector, and the elastic waterproof sleeve is arranged to abut against the outer wall of the first connector. A sealing rubber ring is arranged around the port of the second connector close to the first connector, and the sealing rubber ring is arranged to abut against the wall of the connection groove.
[0014] By adopting the above technical solution, the elastic waterproof sleeve can effectively cover the joint between the connecting groove and the second connector to prevent the intrusion of water vapor. The setting of the sealing rubber ring can effectively fill the gap between the second connector port and the inner wall of the connecting groove to further prevent water vapor from intruding into the connector.
[0015] In summary, the beneficial technical effects of the utility model are:
[0016] 1. The use of heat spreader and heat sink fins can effectively balance the heat in different parts of the connector, while reducing the overall operating temperature of the connector to avoid heat accumulation and burning;
[0017] 2. The heat pipe is used to further disperse and conduct the heat on the cooling fins, avoiding the situation where the local heat on the cooling fins affects the overall heat dissipation power;
[0018] 3. The clamping column is used, which effectively ensures the firmness of the connection between the clamping column and the vehicle body while having good repeated disassembly performance. BRIEF DESCRIPTION OF THE DRAWINGS
