Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0024] A snap-on automobile connection connector comprises a shell 1, wherein a plurality of groups of terminals 2 are inserted inside the shell 1, a bottom plate 4 is fixedly connected to the lower end of the shell 1, the tails of the plurality of groups of terminals 2 are all located between a pressing plate 16 and the shell 1, a clamping plate 10 is clamped on one side of the pressing plate 16 close to the inside of the shell 1, a plurality of groups of slots 11 are penetrated through the clamping plate 10, the tails of the plurality of groups of terminals 2 respectively penetrate the plurality of groups of slots 11, and a snap-on assembly is fixedly connected to one side of the shell 1 close to the tails of the terminals 2.

[0025] like Figure 1-Figure 5 As shown, multiple groups of terminals 2 are arranged in order inside the shell 1, which are used to electrically connect the automobile connection connector with the external structure. A card plate 10 is installed on the base plate 4, and the card plate 10 is fixed on the base plate 4. The center of the tail of the terminal 2 is most susceptible to bending and damage. When the tail of the terminal 2 is tilted or bent by force, the terminal 2 will squeeze the inner wall of the slot 11 of the card plate 10. The slot 11 limits the terminal 2 to prevent the terminal 2 from deforming and bending under force, thereby increasing the connector's ability to protect the terminal 2 and reducing the possibility of damage to the terminal 2. The snap-on assembly facilitates the snap-on installation of the automobile connection connector.

[0026] The multiple groups of terminals 2 are all set to be "L"-shaped, and the multiple groups of terminals 2 are arranged in a linear array. Multiple groups of clamping components are fixedly connected to one side of the clamping plate 10 close to the bottom plate 4, and multiple groups of installation ports are opened through the bottom plate 4.

[0027] like Figure 1 As shown, the "L"-shaped terminal 2 facilitates right-angle connection to external parts, and the snap-on assembly is installed with the mounting opening to facilitate fixation of the card board 10.

[0028] The card-connecting assembly includes two groups of symmetrically arranged plug-in parts 12, which are fixed to a surface of the card plate 10 close to the bottom plate 4, and both groups of plug-in parts 12 pass through the installation opening. Both ends of the two groups of plug-in parts 12 are fixed with bending parts 13, and both groups of bending parts 13 are in contact with the bottom of the bottom plate 4.

[0029] like Figure 1-Figure 3 As shown, when installing the card board 10, the bending portion 13 anticipates that the plug-in portion 12 is in a straight state, the card slot is aligned with the tail of the terminal 2, the bending portion 13 passes through the installation opening, the plug-in portion 12 is located in the installation opening, and then the bending portion 13 is bent so that the bending portion 13 is attached to the bottom of the base plate 4 to fix the position of the card board 10 to prevent it from falling off.

[0030] A fixing frame 14 is fixedly connected to the bottom of the bottom plate 4. The fixing frame 14 is set to be rectangular in shape. A sliding groove 15 is opened on the inner wall of the fixing frame 14. Multiple groups of pressing plates 16 are slidably connected in the sliding groove 15. The multiple groups of pressing plates 16 are respectively pressed and matched with the multiple groups of bending parts 13.

[0031] like Figure 2 and Figure 5 As shown, the fixing frame 14 and the slide groove 15 facilitate the sliding of the pressing plate 16. After the bending portion 13 is bent, the pressing plate 16 is slid to press the pressing plate 16 against the bending portion 13 to prevent the bending portion 13 from restoring its deformation.

[0032] The buckle assembly comprises an inserting column 6 , a springback seam 7 is formed through the middle of the inserting column 6 , grooves 8 are formed on both sides of the springback seam 7 , and a spring 9 is fixedly connected between the two groups of grooves 8 .

[0033] like Figure 1 and Figure 4 As shown, when the connecting connector is buckled, the plug-in column 6 is buckled. The elasticity of the plug-in column 6 may decrease after being buckled for a long time. In order to compensate for the elastic recovery ability of the plug-in column 6, a groove 8 and a spring 9 are added in the plug-in column 6 to increase the recovery ability of the plug-in column 6 so that the end of the plug-in column 6 can be firmly buckled on the external part.

[0034] Guide pillars 3 are fixedly connected to both sides of one side of the housing 1 close to the plug-in assembly, and an elastic buffer pad 5 is fixedly connected to one side of the housing 1 close to the plug-in assembly.

[0035] like Figure 1 As shown, the guide column 3 facilitates the buckling of the joint, and the elastic buffer pad 5 reduces the damage caused by the pressure on the connecting joint.

[0036] The working principle of a snap-on automobile connection joint provided by the utility model is as follows:

[0037] By installing the card board 10 on the base plate 4, the card board 10 is fixed on the base plate 4. The center of the tail of the terminal 2 is most susceptible to bending and damage. When the tail of the terminal 2 is tilted or bent by force, the terminal 2 will squeeze the inner wall of the slot 11 of the card board 10. The slot 11 limits the terminal 2 to prevent the terminal 2 from deforming and bending under force, thereby increasing the connector's ability to protect the terminal 2 and reducing the possibility of damage to the terminal 2. The snap-on assembly facilitates the snap-on installation of the vehicle connection connector.

[0038] 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, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
