Description

Technical Field

[0001] The invention relates to the technical field of automobile accessories, in particular to a rotation-stopping terminal bracket. Background Art

[0002] Grounding wire plays a very important role in automobile circuits. In order to ensure that all parts of the car can work normally, a closed current loop needs to be established. The power battery system inside the vehicle needs to connect the negative pole to the body. This can simplify the circuit connection, reduce the effect of resistance, and improve the working efficiency of the circuit. In this way, the sheet metal frame of the car body becomes a common negative pole, ensuring the smooth flow of current. The wire that connects the sheet metal frame of the car body and the battery box is usually called a grounding wire. Furthermore, it is necessary to set a corresponding bracket at the battery system end for the installation of its grounding wire.

[0003] Upon checking the announcement number: CN210379458U, an angle-adjustable terminal bracket is disclosed. This technology discloses "an angle-adjustable terminal bracket, comprising a fixing part and a mounting part, the fixing part and the mounting part are vertically connected, one end of the mounting part is connected to the fixing part, and the other end of the mounting part is provided with a circular hole, an arc-shaped waist hole is provided on the mounting part, and the center of the arc-shaped waist hole and the center of the circular hole are located at the same point" and other technical solutions, which have "fixing the fixing part on the corresponding equipment when in use, fixing the terminal by two pins or bolts, one of which is set in the circular hole, and the other is set in the arc-shaped waist hole. Since the center of the arc-shaped waist hole and the center of the circular hole are located at the same point, the terminal can be rotated with the circular hole as the center, thereby completing the angle adjustment of the terminal" and other technical effects.

[0004] The existing grounding wire terminal positioning method has the following problems:

[0005] 1. With the help of the existing battery box fixing bracket, or its welded fixing bracket, the grounding wire terminal battery end is bolted by welding the anti-rotation gasket; this form is limited by the bracket position of the battery box itself, and it is possible to overlap with the vehicle fixing point, resulting in the line being too long to be designed, increasing the cost.

[0006] 2. Most of them can only have one installation state, that is, the anti-rotation angle is fixed; after actual installation verification by the OEM, it is possible that the line comes out in a single direction, and the wiring method interferes with other electrical components of the vehicle, or the reinforcement beams on the frame. Summary of the invention

[0007] In view of the deficiencies in the prior art, the present invention provides a anti-rotation terminal bracket, and the grounding wire harness has two lead-out methods at different angles, which can flexibly adjust the effective wire harness length connected to the vehicle end, thereby greatly increasing the convenience of grounding wire installation.

[0008] To achieve the above objectives, the present invention is implemented through the following technical solutions: a rotation-stopping terminal bracket, comprising an outer wall of a battery box body and a grounding wire, a bracket mechanism is provided on the outer wall of the battery box body and is used to connect and fix the grounding wire, a protective mechanism is provided on the grounding wire and is used to protect insulation, and the bracket mechanism comprises:

[0009] The main assembly includes a terminal bracket mounted on the outer wall of the battery box, a mounting hole opened inside the terminal bracket, a nut fixed to the rear end of the terminal bracket and concentric with the mounting hole, and a left anti-rotation groove and a right anti-rotation groove respectively opened on both sides of the front end of the terminal bracket;

[0010] The terminal assembly comprises a fastening part wrapped and installed on the end of the grounding wire, a terminal head integrally formed on the fastening part, and a bending part integrally formed at the end of the terminal head.

[0011] Preferably, the main body assembly further comprises a bolt penetrating through the fastening portion and the terminal bracket and threadedly mounted with the nut, and is used to fix the terminal assembly on the grounding wire to the main body assembly on the outer wall of the battery box.

[0012] Preferably, the main body assembly further comprises fixing parts integrally formed at both end portions of the terminal bracket, and the terminal bracket is welded to the outer wall of the battery box through the fixing parts.

[0013] Preferably, the bending portion cooperates with the left anti-rotation groove and the right anti-rotation groove, and a gap of 0.3mm-1.5mm is reserved.

[0014] Preferably, the protection mechanism comprises a protection sleeve mounted on the terminal head, clamping sleeves mounted on both ends of the protection sleeve, and a plurality of circumferentially distributed grooves formed on the outer edges of both ends of the protection sleeve.

[0015] Preferably, the protection mechanism further comprises a ring seat fixed at the middle part of the outer wall of the protection sleeve, external thread grooves formed on the outer walls at both ends of the protection sleeve, and internal thread grooves formed on the inner wall of the clamping sleeve.

[0016] Preferably, the protection mechanism further comprises a soft rubber ring installed inside the clamping sleeve, and the soft rubber ring is embedded and installed inside the outer end of the clamping sleeve.

[0017] Preferably, the outer walls at both ends of the protective sleeve are of a structure that is small outside and large inside, and the outer end of the inner wall of the clamping sleeve is of a structure that is small outside and large inside.

[0018] The present invention provides a rotation-stopping terminal bracket. Compared with the prior art, it has the following beneficial effects:

[0019] 1. By adapting the left and right anti-rotation grooves, when the terminal assembly is connected to the main assembly, the torque of the bolt is transmitted to the left or right anti-rotation grooves, so that the grounding wire is guaranteed to be in its predetermined outlet position after installation, avoiding the tail of the grounding wire from rotating with the torque, and facilitating the fixation of the grounding wire; at the same time, by opening the left and right anti-rotation grooves on the left and right sides respectively, when the terminal assembly is installed, there are two outlet angles with different angles, and the wire harness outlet angle is flexible. In this way, the effective wire harness length connected to the vehicle end can be flexibly adjusted, thereby greatly increasing the convenience of grounding wire installation.

[0020] 2. By screwing in the bolt, the bent part in the terminal assembly can be smoothly inserted into the right-side anti-rotation groove, and the terminal assembly and the main assembly can be tightly combined through the action of torque; when the torque is transmitted to the right-side anti-rotation groove, the terminal assembly can be limited to ensure the lead-out angle; by the same token, when the lead-out direction or length of the grounding wire needs to be flexibly changed, the left-side anti-rotation groove can be used to achieve the change in the lead-out direction of the harness, so as to avoid interference or adjust the effective harness connection length.

[0021] 3. After the terminal head in the terminal assembly is connected to the grounding wire, the protective sleeve with tightening sleeves on both ends is put on the terminal head again, and the tightening sleeve is rotated and tightened to squeeze the protective sleeve. After the protective sleeve is tightened, the terminal head is fixed, thereby fastening the terminal head and the grounding wire, and the protective mechanism is fixed on the terminal head as a whole; and the connection between the terminal head and the grounding wire is protected by the protective mechanism to prevent the connection from loosening due to external factors.
