Referring to fig. 1, a two-in-one plugging structure 10 includes a whole vehicle assembly 100, a debugging assembly 200 and a main plug 300, the whole vehicle assembly 100 includes a whole vehicle plug 110 and a whole vehicle cable 120, one end of the whole vehicle cable 120 is connected with the whole vehicle plug 110, the debugging assembly 200 includes a debugging plug 210 and a debugging cable 220, one end of the debugging cable 220 is connected with the debugging plug 210, the end of the whole vehicle cable 120 away from the whole vehicle plug 110 and the end of the debugging cable 220 away from the debugging plug 210 are close together to form a main cable 400, and the main cable 400 is connected with the main plug 300.

It should be noted that the entire car plug 110 is connected to the entire car cable 120, wherein a metal ferrule is installed in the entire car plug 110, and the entire car cable 120 is electrically connected to the metal ferrule in the entire car plug 110; similarly, the debug plug 210 is connected to the debug cable 220, a metal ferrule is also installed in the debug plug 210, and the debug cable 220 is electrically connected to the metal ferrule in the debug plug 210. Then, the end of the entire car cable 120 away from the entire car plug 110 and the end of the debugging cable 220 away from the debugging plug 210 are combined to form an overall cable 400 in which the entire car cable 120 and the debugging cable 220 are integrated together, wherein the overall cable 400 is connected with the overall plug 300, for example, a metal ferrule is also installed in the overall plug 300, and both the entire car cable 120 and the debugging cable 220 forming the overall cable 400 are electrically communicated with the metal ferrule in the overall plug 300. It should be noted that the metal ferrule in the debug plug 210 and the metal ferrule in the vehicle plug 110 do not realize the electrical core communication through a wire, that is, the debug plug 210 and the vehicle plug 110 are electrically independent structures. In one embodiment, the entire vehicle cable 120 and the debugging cable 220 are both of a wire harness structure. Therefore, the conventional whole vehicle cable 120 and the debugging cable 220 are separately arranged, which means that two independent cable structures are required to be used, and the two-in-one plugging structure 10 of the application enables the whole vehicle plug 110 plugged into the whole vehicle system and the debugging plug 210 used for debugging and testing to share the main plug 300, so that only one socket needs to be arranged on the high-voltage distribution box, the debugging socket does not need to be additionally reserved, the debugging plug 210 can install the debugging plug 210 on any position of the vehicle by prolonging the length of the debugging cable 220 according to the actual condition of the vehicle, and the plugging difficulty of communication with the high-voltage distribution box during debugging is reduced.

Need extra installation debugging socket on conventional high voltage distribution box, this debugging socket need use before the vehicle leaves the factory, after the vehicle leaves the factory, just need use waterproof, shield or end cap etc. to plug up. Since the high voltage distribution box is usually installed in a hidden location of the vehicle, it may cause difficulty in plugging during debugging if the conventional design is adopted. And in the vehicle use in later stage, if the conventional sets up extra debugging socket on the high voltage distribution box, after waterproof, shield or end cap on the debugging socket drop off, because the high voltage distribution box position is hidden, lead to debugging the problem that the socket exposes to be difficult to discover, this means that the high voltage distribution box has realized the contact through this debugging socket with the external world, leads to external moisture, dust etc. to get into in the high voltage distribution box, endangers the high voltage distribution box. And use two unification plug structure 10 of this application, can share the interface, need not install extra socket on high voltage distribution box for the debugging plug 210 that supplies the engineer debugging to use can install the department in any position of vehicle as required, consequently can make things convenient for the engineer to use debugging plug 210 to peg graft, avoids the grafting difficulty. When the debugging plug 210 is not needed to be used, the debugging plug 210 also needs to be plugged by a waterproof and dustproof cover or a plug, and the installation position of the debugging plug 210 is not hidden any more, so that the debugging plug can be found in time when the waterproof and dustproof cover or the plug is loosened by vibration. Moreover, even if the commissioning plug 210 is in contact with the outside for a long time, since the commissioning cable 220 is still spaced between the commissioning plug 210 and the high-voltage distribution box, moisture and dust from the outside cannot directly enter the high-voltage distribution box, so that the safety of the high-voltage distribution box can be improved.

It should be noted that one end of the locking swing plate 113 is fixedly mounted on the seat body 111, and the other end of the locking swing plate 113 faces in a direction away from the vehicle cable 120, and it should be noted that the end of the vehicle cable 120 away from the locking swing plate 113 is a free end, i.e. is not fixedly connected to the seat body 111, and therefore can slightly swing along the radial direction of the seat body 111. Wherein the free end of the locking swing plate 113 is provided with a barb on the side facing the seat 111. Further, the sliding block 114 can slide along the seat body 111 to be close to or far away from the vehicle cable 120, when the sliding block 114 slides on the seat body 111 to be far away from the vehicle cable 120, the sliding block 114 pushes the locking swing plate 113, and the locking swing plate 113 deforms under stress, so that the free end of the locking swing plate 113 moves inward along the radial direction of the seat body 111, that is, the free end of the locking swing plate 113 is close to the seat body 111 along the radial direction of the seat body 111, wherein the radial direction of the seat body 111 is the direction perpendicular to the sliding direction of the sliding block 114. As the free end of the locking swing plate 113 approaches the base 111, the barbs on the free end of the locking swing plate 113 will approach the base 111. Thus, when the entire vehicle plug 110 is inserted into the socket on the vehicle, the barb will catch the socket, thereby locking the entire vehicle plug 110 to the socket. When the sliding block 114 slides on the seat body 111 to approach the cable 120, the sliding block 114 does not push the locking swing plate 113 any more, so that the free end of the locking swing plate 113 is far away from the seat body 111 along the radial direction of the seat body 111 under the action of the self-restoring force. So that the barbs can be withdrawn from the socket, and the whole vehicle plug 110 can be withdrawn from the socket. Thus, the locking swing plate 113 is pushed by the sliding block 114, so that the whole vehicle plug 110 can be locked to the socket, and the plugging stability of the whole vehicle plug 110 is improved.
