In a first aspect of the present application, a high-voltage harness plugging and fixing assembly 10 is provided, fig. 1 is a schematic structural diagram of an embodiment of the high-voltage harness plugging and fixing assembly 10 provided in the present application, and fig. 2 is a schematic structural diagram of the high-voltage harness 30 plugging and fixing assembly shown in fig. 1 disposed on a vehicle distribution box 20.

Referring to fig. 1 and 2, the high-voltage harness plugging and fixing assembly 10 includes a first fixing member 11 and a second fixing member 12, the first fixing member 11 is disposed on an outer wall of the vehicle distribution box 20, and the second fixing member 12 is fixed to an outer wall of an end portion of the high-voltage harness 30. During the insertion of the high-voltage harness 30 into the vehicle power distribution box 20, the first fixing member 11 is connected with the second fixing member 12 such that the high-voltage harness 30 is firmly inserted into the vehicle power distribution box 20.

Specifically, a connection port (not shown) is provided on the vehicle distribution box 20, and the connection port is used for being connected with the high-voltage harness 30, so as to connect the connection harness in the vehicle distribution box 20 with the high-voltage harness 30, and further achieve power transmission. The first fixing member 11 is disposed at a distance from the connection port of the vehicle distribution box 20, and a limit projection 111 is provided on a side wall of the first fixing member 11. The first fixing member 11 may be provided in a plate shape, a cylindrical shape, a block shape, or the like, and the shape of the first fixing member 11 is not limited in this embodiment, and fig. 1 and 2 exemplarily show the first fixing member 11 as a cylindrical shape. The side wall of the first fixing member 11 is provided with a limiting protrusion 111, which may be an inner side wall of the first fixing member 11 near the connection port side or an outer side wall of the first fixing member 11 far from the connection port side, and is not particularly limited in this embodiment.

The second fixing member 12 is provided with a limiting arm 121, the limiting arm 121 is arranged at intervals with the outer wall of the high-voltage wire harness 30, and a limiting groove 1211 penetrating through the limiting arm 121 is formed in the limiting arm 121. The limiting arm 121 may be provided in a strip shape, and the second fixing member 12 may include some other structure besides the limiting arm 121. For example, the second fixing member 12 includes a fixing structure and a limiting arm 121, where the fixing structure is used to fix the limiting arm 121 on the high voltage wire harness 30. Of course, the second fixing member 12 may include only the limiting arm 121, and is not particularly limited in this embodiment. The second fixing member 12 is illustrated in fig. 2 as a cylindrical shape by way of example, but not limited thereto in other embodiments, for example, the first fixing member 11 and the second fixing member 12 are each provided in a stripe shape. The spacing arm 121 is spaced from the outer wall of the high voltage harness 30 to form a mounting gap that can accommodate the entry of the first fastener 11. The shape and size of the limit groove 1211 may be matched with those of the limit protrusion 111 so that the limit protrusion 111 can be engaged into the limit groove 1211. The limiting groove 1211 is illustratively shown as a longer groove in fig. 1 and 2, where the size of the limiting groove 1211 is larger, and in other embodiments the size of the limiting groove 1211 may be only slightly larger than the size of the limiting boss 111 to better limit the limiting boss 111.

In combination with the above, during the process of plugging the high-voltage harness 30 into the connection port of the distribution box, the second fixing member 12 approaches to the first fixing member 11, and at this time, the first fixing member 11 enters into the installation gap between the limiting arm 121 and the high-voltage harness 30. It should be appreciated that when the first fixing member 11 enters the installation gap between the limiting arm 121 and the high-voltage harness 30, the spacing between the limiting arm 121 and the inner wall of the first fixing member 11 is smaller, and the protrusion height of the limiting protrusion 111 is higher. At this time, if the limiting arm further slides relative to the first fixing element 11, the limiting protrusion 111 will abut against the limiting arm 121, so that the limiting arm 121 is elastically deformed, and the limiting protrusion 111 slides on the limiting arm 121 to be finally slidably engaged into the limiting groove 1211, so as to achieve the relative fixing of the first fixing element 11 and the second fixing element 12.

In summary, through the above embodiment, in the process of plugging the high-voltage harness 30 into the connection port, the second fixing member 12 on the high-voltage harness 30 and the first fixing member 11 on the vehicle distribution box 20 are mutually matched to achieve fixation, so as to strengthen the high-voltage harness 30 to be firmly plugged into the connection port.

Referring to fig. 3-8, in some embodiments, the first fixing member 11 and the second fixing member 12 are both configured in a tubular shape, the connection port is located in the first fixing member 11, the second fixing member 12 is sleeved on the end of the high-voltage wire harness 30, and the second fixing member 12 is sleeved on the first fixing member 11 so that the high-voltage wire harness 30 is connected with the connection port. The bottom end of the first fixing member 11 is connected to the outer wall of the vehicle distribution box 20, and may be welded between the end of the first fixing member 11 and the outer wall of the vehicle distribution box 20. The peripheral wall of one end of the first fixing member 11 is disposed around the peripheral wall of the connection port so that the connection port is located within the first fixing member 11. When the second fixing member 12 is sleeved on the end of the high-voltage harness 30, the end of the high-voltage harness 30 extends out of the second fixing member 12, so that the extending portion can be inserted into the connection port.

It should be appreciated that, through the connection mode that the second fixing member 12 is sleeved on the first fixing member 11, a more firm connection between the first fixing member 11 and the second fixing member 12 can be achieved, so as to ensure the connection stability of the high-voltage wire harness 30.

Referring to fig. 3 and fig. 4, in some embodiments, an outer wall of the first fixing member 11 is provided with a protruding engaging strip 112, one end of the engaging strip 112 away from the vehicle distribution box 20 forms a limiting protruding portion 111, and the engaging strip 112 is located on a side of the limiting protruding portion 111 close to the vehicle distribution box 20 to form an engaging groove 113. The locking strip 112 may extend along the axial direction of the first fixing member 11, at this time, the limiting protrusion 111 is located at one end of the locking strip 112 away from the vehicle distribution box 20, and the locking slot 113 is divided into two structures of the limiting protrusion 111 and other parts by the locking strip 112.

Referring to fig. 1, 6 and 7, an engagement section 1212 is formed between the limit groove 1211 and the end wall of the second fixing member 12 adjacent to the vehicle distribution box 20, and when the limit protrusion 111 is engaged in the limit groove 1211, the engagement section 1212 is engaged in the engagement groove 113. The shape and size of the clamping section 1212 can be matched with those of the clamping groove 113, so that the clamping section 1212 can be firmly clamped into the clamping groove 113. Through the arrangement of the clamping section 1212 and the clamping groove 113, besides the clamping connection between the first fixing piece 11 and the second fixing piece 12 is realized through the limiting protruding portion 111 and the limiting groove 1211, the clamping connection is realized through the matching of the clamping section 1212 and the clamping groove 113, and further the first fixing piece 11 and the second fixing piece 12 have a good fixing effect.

In this embodiment, the limiting groove 1211 may be configured as a longer bar-shaped groove because the engagement between the engagement section 1212 and the engagement groove 113 can achieve a better connection between the first fixing member 11 and the second fixing member 12. For example, an end of the stopper groove 1211 remote from the vehicle distribution box 20 may penetrate an end of the second fixing member 12, so that the stopper arm 121 has better elasticity. At this time, when the limit projection 111 engages with the limit groove 1211, the limit groove 1211 achieves the limit of the limit projection 111 in the circumferential direction of the second fixing member 12.

Referring to fig. 6 and 7, in some embodiments, the limiting arm 121 extends along the axial direction of the second fixing member 12, and the limiting arm 121 is formed with a clearance groove 122 on one side of the circumferential side wall of the second fixing member 12, and the clearance groove 122 penetrates the second fixing member 12 to be close to the end wall of the vehicle distribution box 20. The two sides of the limiting arm 121 in the circumferential direction of the second fixing piece 12 are respectively formed with a clearance groove 122, so that the limiting arm 121 is arranged at intervals relative to other parts of the second fixing piece 12, and further the limiting arm 121 has certain elasticity, and the limiting protruding portion 111 is conveniently clamped into the limiting groove 1211.

Referring to fig. 3 and 4, the outer wall of the first fixing member 11 is provided with a limiting bar 114, and the limiting bar 114 extends along the axial direction of the first fixing member 11. Wherein, when the second fixing member 12 moves on the first fixing member 11 such that the limiting protrusion 111 is engaged with the limiting groove 1211, the limiting bar 114 is engaged with the clearance groove 122.

Specifically, the limiting strips 114 are spaced apart from the engaging strips 112, and the limiting strips 114 are parallel to the engaging strips 112. The two clamping strips 112 can be correspondingly arranged at the moment in combination with the embodiment that the clearance grooves 122 are formed on the left side and the right side of the limiting arm 121, and the two clamping strips 112 can be respectively clamped into the two clearance grooves 122 at the moment, so that a more stable connecting effect between the first fixing piece 11 and the second fixing piece 12 is realized.

In some embodiments, the limiting strip 114 and the locking strip 112 are a set of fixed structures. On the outer wall of the first fixing member 11, a plurality of sets of fixing structures may be formed to achieve good fixation between the first fixing member 11 and the second fixing member 12. For example, two sets of fixing structures are shown in fig. 5, and the two sets of fixing structures are symmetrically disposed to be located at the upper and lower portions of the first fixing member 11, respectively.

Referring to fig. 6 and 7, in some embodiments, a bottom wall is formed on a side of the clearance groove 122 away from the end wall of the second fixing member 12, and when the limiting protrusion 111 is engaged in the limiting groove 1211, the end wall of the limiting bar 114 abuts against the bottom wall of the limiting groove 1211. In combination with the above, during the approaching of the second fixing member 12 with respect to the first fixing member 11, the end of the stopper 114 gradually approaches the bottom wall of the stopper groove 1211. When the limiting protrusion 111 is engaged with the limiting groove 113 and the engaging section 1212 is engaged with the engaging groove 113, the end wall of the limiting bar 114 abuts against the bottom wall of the limiting groove 1211, so that the first fixing member 11 and the second fixing member 12 are limited in the axial direction of the second fixing member 12.

Referring to fig. 6 and 7, in some embodiments, the side walls of the second mount 12 are provided with ravines 123, the ravines 123 extending through the end walls of the second mount 12 near the ends of the vehicle distribution box 20.

Specifically, the snap ring sleeve 124 has a metal structure and a certain elasticity. During the movement of the second fixing member 12 towards the first fixing member 11, the first fixing member 11 enters into a gap between the clamping spring sleeve 124 and the limiting arm 121, and at this time, the first fixing member 11 compresses the clamping spring sleeve 124 to a certain extent. It should be understood that the structure on the side wall that the jump ring cover 124 contacts with the first fixing piece 11 is wave-shaped, so that a larger friction force exists between the jump ring cover 124 and the first fixing piece 11, and the jump ring cover 124 has a certain pressing effect on the first fixing piece 11, so that the first fixing piece 11 can be well fixed with the second fixing piece 12 relatively.
