[0006] Preferably, a sealing ring is installed on the outer side of one end of the housing close to the plug-in terminal.

[0007] Preferably, the housing is composed of two symmetrical snap-in plates, which are snap-fitted with each other.

[0008] Preferably, the sealing baffle is an arc-shaped structure, and the outer side is attached to the surface of the plug-in terminal.

[0009] Preferably, a side of the pressing block close to the spring is a horizontal structure, and a side of the pressing block close to the pressing plate is an inclined structure.

[0010] Preferably, a gasket is installed on a side of the end of the sealing baffle close to the plug-in terminal.

[0011] Preferably, a protective cover is installed on the top outer wall of the shell, and mounting feet are installed on the bottom of both sides of the protective cover.

[0012] Preferably, the number of the springs is three, and all of them are arranged in parallel with equal intervals.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] In the convenient plug-in and unplug-in automobile connector, by setting structures such as a clamping assembly and a spring, the plug-in terminal can fit tightly together when connected to the external connection plug, and can be easily plugged in and out. This greatly improves the convenience of use of the connector. Due to the effect of the clamping assembly and the spring, the plug-in terminal is more stable and reliable when connected and is not easy to loosen. At the same time, the setting of the sealing baffle and the sealing ring further enhances the sealing performance of the connector and effectively prevents dust from entering the inside of the connector. The setting of the protective cover makes the appearance of the connector more beautiful and generous. At the same time, the setting of the mounting foot also makes it easier to fix the connector on the car. Since the connector has the characteristics of convenient plug-in and pull-out, stability and reliability, and beautiful appearance, it can be widely used in various automobiles.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides a car connector which is convenient for plugging and unplugging, such as Figure 1-Figure 4 As shown, it includes a shell 2, a circuit board 7 is arranged inside the shell 2, a plug-in terminal 3 is installed at one end of the circuit board 7, and a wiring terminal 5 is installed at the other end of the circuit board 7. A clamping assembly 6 is installed on the upper and lower inner walls of the shell 2 near the plug-in terminal 3. The clamping assembly 6 includes a pressing plate 61, a pressing block 64 is installed on the inner side of the pressing plate 61, a sealing baffle 62 is installed at one end of the pressing plate 61, and a plurality of springs 65 are installed between the outer side of the pressing block 64 and the inner wall of the shell 2. One end of the pressing plate 61 is rotatably connected to the inner wall of the shell 2 through a hinge 63, and pressure is applied to the pressing plate 61 through the spring 65, so that the pressing plate 61 is pressed onto the plug of the external connection device, so that the metal sheet of the plug fits tightly with the plug-in terminal 3 to ensure that it will not loosen after plugging.

[0023] In this embodiment, a sealing ring 4 is installed on the outer side of one end of the housing 2 close to the plug-in terminal 3 to ensure that the plug-in terminal of the housing 2 remains sealed after being plugged in.

[0024] Specifically, the housing 2 is composed of two symmetrical snap-in plates 21 , and the snap-in plates 21 are snap-fitted to each other, so as to facilitate the assembly and disassembly of the housing 2 .

[0025] Furthermore, the sealing baffle 62 is an arc-shaped structure, and its outer side is attached to the surface of the plug-in terminal 3 to seal the outer side of the plug-in terminal 3 to prevent dust from entering the interior of the housing 2 .

[0026] Furthermore, a side of the pressing block 64 close to the spring 65 is a horizontal structure, and a side of the pressing block 64 close to the pressing plate 61 is an inclined structure.

[0027] Furthermore, a gasket 621 is installed on one side of the end of the sealing baffle 62 close to the plug-in terminal 3 , which is used to cushion the end of the sealing baffle 62 to avoid abrasion to the plug-in terminal 3 .

[0028] Furthermore, a protective cover 1 is installed on the top outer wall of the housing 2 , and mounting feet 11 are installed on the bottom of both sides of the protective cover 1 for mounting and fixing the protective cover 1 .

[0029] Furthermore, there are three springs 65 , which are arranged in parallel and at equal intervals.

[0030] When the convenient plug-in and unplug-in automobile connector of the utility model is used, first when it is necessary to plug the plug of the external connection device into the plug terminal 3 of the device, the plug is inserted first. At this time, because the pressure plate 61 has a certain pressure under the action of the spring 65, the pressure plate 61 can be tightly pressed on the plug. As the plug is inserted, the metal sheet on the plug gradually fits with the plug terminal 3. Since the sealing baffle 62 is an arc-shaped structure, its outer side can fit tightly on the surface of the plug terminal 3, further enhancing the sealing of the connection. At the same time, the gasket 621 can effectively prevent the sealing baffle 62 from causing wear to the plug terminal 3. When it is necessary to unplug the plug, the plug can be easily unplugged by pulling the shell 2 outward. Since there are three springs 65, all of which are arranged in parallel and at equal intervals, the connector is more stable and reliable.

[0031] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
