Description

Technical Field

[0001] The utility model specifically relates to an EMC connector for electric control of new energy vehicles, belonging to the technical field of EMC connectors. Background Art

[0002] Electromagnetic compatibility (EMC) refers to the ability of a device or system to operate in accordance with requirements in its electromagnetic environment and not cause intolerable electromagnetic interference to any device in its environment. Therefore, EMC includes two requirements: on the one hand, the electromagnetic interference generated by the device to the environment during normal operation cannot exceed a certain limit; on the other hand, it means that the device has a certain degree of immunity to the electromagnetic interference in the environment, that is, electromagnetic sensitivity. In the field of automotive electronics, especially in the field of new energy vehicles, EMC connectors have been widely used to realize power transmission. Stable and reliable connectors are also the key to solving the EMC problem of automotive power transmission lines.

[0003] The current EMC connector only relies on the plastic card block on the plug for clamping and fixing after connection. Not only is the clamping not firm enough, but also during use, if the connector is accidentally splashed with water, it is easy for water to seep in from the connection position of the connector. In view of this, the utility model proposes an EMC connector for new energy vehicle electronic control. Utility Model Content

[0004] The purpose of the utility model is to address the deficiencies of the prior art and provide an EMC connector for electric control of new energy vehicles, which can be stably fixed after connection, thereby improving the stability of the connector during transmission, and the connector can also effectively prevent water from seeping in from the joints of the connector.

[0005] The utility model achieves the above-mentioned purpose through the following technical solutions: an EMC connector for electronic control of new energy vehicles, including a transmission female head and a transmission male head, a limiting baffle plate 1 is fixedly installed on the transmission female head, and a limiting baffle plate 2 is fixedly installed on the transmission male head, guide columns are respectively installed on the two side walls of the transmission male head, a lifting plate is slidably clamped on the guide column, a lower pressure plate is installed on one side wall of the lifting plate, a limiting groove is provided on the lower pressure plate, a supporting spring 1 for supporting the lifting plate is arranged on the side wall of the guide column, and clamping components for limiting the lower pressure plate are respectively installed on the two side walls of the transmission male head.

[0006] Furthermore, in order to improve the sealing performance between the first limiting baffle and the second limiting baffle, a sealing gasket is provided on one side wall of the second limiting baffle.

[0007] Furthermore, in order to enable the lower pressure plate to better drive the limit baffle plate 1 and the limit baffle plate 2 to fit each other, a guide slope is provided on one side wall of the limit baffle plate 1 and the limit baffle plate 2.

[0008] Furthermore, in order to limit the lower pressure plate, the clamping assembly includes a support vertical plate, the support vertical plate is located on the transmission male head, the support vertical plates are respectively slidably clamped with guide shafts, one end of the guide shaft is installed with an L-shaped limit block, and the support vertical plate is connected with a threaded rod.

[0009] Furthermore, in order to facilitate the twisting of the threaded rod, a knob head is installed at one end of the threaded rod.

[0010] Furthermore, in order to drive the L-shaped limit block to retreat after loosening the threaded rod, a second support spring for supporting the support vertical plate is provided on the side wall of the guide shaft.

[0011] Furthermore, in order to improve the stability and waterproof effect of the EMC connector, a positioning groove is provided inside the transmission female connector, and a support ring is installed on one side wall of the transmission male connector.

[0012] Furthermore, in order to improve the heat dissipation effect of the EMC connector, heat dissipation fins are respectively installed on both side walls of the transmission female connector.

[0013] The technical effects and advantages of the utility model are as follows: the L-shaped limit block can drive the lower pressure plate to descend, so that the lower pressure plate can limit the limit baffle plate 1 on the transmission female head and the limit baffle plate 2 on the transmission male head, which is beneficial to the stable connection between the transmission female head and the transmission male head. Therefore, the EMC connector has good stability and fixation after connection. At the same time, after the lower pressure plate descends, the limit baffle plate 1 and the limit baffle plate 2 can be squeezed by the lower pressure plate, thereby squeezing the sealing gasket between the limit baffle plate 1 and the limit baffle plate 2, which is beneficial to prevent water stains from penetrating into the interior of the EMC connector from the joint between the transmission female head and the transmission male head.

[0023] The sealing gasket 10 is made of rubber. The rubber gasket has good sealing performance and elasticity and can work in harsh environments such as high temperature, high pressure and corrosion. Common rubber gaskets include nitrile rubber, fluororubber, silicone rubber, etc. A guide slope 12 is provided on one side wall of the limit baffle 1 3 and the limit baffle 2 4. The clamping assembly 8 includes a support vertical plate 801, and the support vertical plate 801 is located on the transmission male head 2. The support vertical plate 801 is respectively slidably connected with a guide shaft 802, and an L-shaped limit block 803 is installed at one end of the guide shaft 802. A threaded rod 804 is connected to the support vertical plate 801. When installing the connector, first insert the probe on the transmission male head 2 into the probe hole on the transmission female head 1. When the two are plugged into place, the limit baffle 1 3 on the transmission female head 1 and the sealing gasket 10 on the limit baffle 2 4 are fitted to each other, and then the threaded rod 804 is twisted to pass through the thread The rod 804 drives the L-shaped limit block 803 to move, so that the L-shaped limit block 803 can drive the lower pressure plate 7 to descend, so that the lower pressure plate 7 can limit the limit baffle 1 3 on the transmission female head 1 and the limit baffle 2 4 on the transmission male head 2, which is beneficial to improve the stability of the transmission female head 1 and the transmission male head 2 after connection, so that the EMC connector can maintain good stability after connection, and after the lower pressure plate 7 descends, the limit groove inside it and the guide inclined surface 12 on the limit baffle 1 3 and the limit baffle 2 4 will fit each other, so that the limit groove can squeeze the limit baffle 1 3 and the limit baffle 2 4, and then squeeze the sealing gasket 10 between the limit baffle 1 3 and the limit baffle 2 4, which can prevent water stains from penetrating into the interior of the EMC connector from the joint between the transmission female head 1 and the transmission male head 2, which is beneficial to improve the waterproof effect of the EMC connector.

After being plugged in place, the limit baffle 1 3 on the transmission female head 1 will fit with the sealing gasket 10 on the limit baffle 2 4. Then, by twisting the threaded rod 804, it can drive the L-shaped limit block 803 to move, and the L-shaped limit block 803 can drive the lower pressure plate 7 to descend, so that the lower pressure plate 7 can limit the limit baffle 1 3 on the transmission female head 1 and the limit baffle 2 4 on the transmission male head 2, thereby facilitating the transmission of the transmission female head. The head 1 is stably connected to the transmission male head 2, so the EMC connector has good stability and fixation after connection. At the same time, after the lower pressure plate 7 is lowered, the limiting groove inside it fits with the guide slope 12 on the limiting baffle 1 3 and the limiting baffle 2 4, so that the lower pressure plate 7 can squeeze the limiting baffle 1 3 and the limiting baffle 2 4, thereby squeezing the sealing gasket 10 between the limiting baffle 1 3 and the limiting baffle 2 4, which is beneficial to prevent water stains from penetrating into the interior of the EMC connector from the joint between the transmission female head 1 and the transmission male head 2.
