[0030] 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.

[0031] like Figure 1~Figure 4As shown, a wiring harness through-hole connector structure described in Example 1 of the utility model includes a connector body 4 and a tail cover 1 detachably connected to the connector body 4, and the wire 5 is arranged to pass through the connector body 4 and the tail cover 1. A wire clamp 2 for fixing the wire 5 is provided between the connector body 4 and the tail cover 1. The wire clamp 2 is sleeved on the outside of the wire 5, and the tail cover 1 is sleeved on the outside of the wire clamp 2. The upper part of the wire clamp 2 is clamped with the tail cover 1, and the wire clamp 2 is squeezed and clamped to tighten the wire 5 through the clamping action of the tail cover 1 to prevent the axial movement of the wire 5. A mushroom head is provided at the lower part of the wire clamp 2 for plugging and matching with other components. A matching anti-error structure is provided between the connector body 4 and the wire clamp 2 to prevent an unmatched wire clamp from being installed in the connector body 4.

[0032] Further, Figure 2 and Figure 3 As shown, the upper side of the connector body 4 is provided with a docking portion 41 extending upward and snap-fitting with the tail cover 1, and the docking portion 41 is approximately a rectangular cylinder with an open upper end. The wire clamp 2 is provided with a mounting platform that fits with the inner side of the rectangular cylinder, and the mounting platform is provided with a through hole for the wire 5 to pass through. The anti-error structure includes an anti-error groove 411 arranged on the docking portion 41 and an anti-error boss 21 arranged on the mounting platform of the wire clamp 2. The anti-error groove 411 is arranged at the upper end of the rectangular cylinder. The anti-error boss 21 is a piece that extends outward from the position corresponding to the anti-error groove 411 on the mounting platform. The anti-error boss 21 fits with the anti-error groove 411, that is, the anti-error boss 21 extending outward on the mounting platform can just be snapped into the anti-error groove 411 from top to bottom, so as to prevent the mismatched wire clamp from being installed in the connector body 4.

[0033] Embodiment 2 is different from Embodiment 1 in that Figure 3 As shown, the wire clamp 2 is provided with a plurality of elastic clips arranged in an annular manner, that is, a plurality of elastic clips are provided on the upper side of the mounting platform around the through hole for the wire 5 to pass through, and are used to surround the outside of the wire 5; the inner side of the tail cover 1 is provided with a wedging groove 12 that cooperates with the elastic clip, which is used to squeeze the elastic clip when the tail cover 1 is clamped and fixed with the connector body 4, so that the elastic clip tightens the wire 5.

[0034] Embodiment 3 is different from Embodiment 1 in that Figure 4 As shown, the tail cover 1 is provided with a downwardly extending hanging platform for being sleeved on the outside of the docking portion 41 and being engaged with the docking portion 41. The connection mode in which the hanging platform is sleeved on the docking portion 41 not only makes the connection firm, but also plays a role in preventing errors, thereby preventing an oversized or undersized tail cover 1 from being connected to the connector body 4.

[0035] Furthermore, if Figure 4As shown, a block 412 is provided on the outside of the docking portion 41, and a slot 11 that is tightly matched with the block 412 is provided on the hanging platform. In this embodiment, blocks 412 are provided on the left and right outer sides of the docking portion 41, and a hollowed-out slot 11 is provided at a corresponding position on the hanging platform. When the hanging platform is sleeved on the outside of the docking portion 41, after the lower edge of the slot 11 passes over the block 412, the block 412 passes through the hollowed-out slot 11, so that the lower edge of the slot 11 is stuck at the lower end of the block 412. The upper side of the block 412 is an inclined surface that tilts outward and downward, and the lower side of the block 412 is a plane perpendicular to the outer wall of the docking portion 41, so that the lower edge of the slot 11 passes over the upper side of the block 412 from top to bottom and then gets stuck at the lower side of the block 412.

[0036] Embodiment 4 is different from Embodiment 3 in that Figure 4 As shown, an opening 111 is provided at the end of the card slot 11, i.e., the inner side of the lower edge of the card slot 11, so that a gap is formed between the lower edge of the card slot 11 and the outer wall of the docking portion 41. The gap is used for inserting a tool to apply force outward to separate the card block 412 from the card slot 11, thereby achieving the purpose of quick release. The position of the card block 412 corresponding to the opening 111 is disconnected with a gap, so that the opening 111 can be exposed.

[0037] Embodiment 5 is different from Embodiment 4 in that Figure 4 As shown, the card block 412 is provided with two layers, and both layers of the card blocks 412 can cooperate with the card slot 11 to form different installation positions of the tail cover 1. When the card slot 11 cooperates with the upper card block 412, the pre-installation position of the tail cover is formed, at which time, the wires inserted into the connector body and passing through the wire clamp and the tail cover can be adjusted; when the card slot 11 cooperates with the lower card block 412, the tail cover reaches a locked state, and the wires can be fixed by the wire clamp.

[0038] Embodiment 6 is different from Embodiment 1 in that Figure 2 As shown, a sealing body 3 is clamped between the wire clamp 2 and the connector body 4. In this embodiment, the sealing body 3 is a convex rib type sealing body. The mushroom head at the lower end of the wire clamp 2 is inserted into the sealing body 3 for clamping and connecting the wire clamp 2 and the sealing body 3.

[0039] Embodiment 7 is different from Embodiment 1 in that Figure 1 As shown, the connector body 4 is provided with a mounting hole for inserting a blind hole nut, which is used for installing and fixing the connector.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
