Detailed Implementation

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0024] The embodiments of this utility model will be described below based on its overall structure.

[0025] A wire harness connector with a built-in retaining clip, such as Figures 1 to 7 As shown, the connector body 100 includes a snap-fit ​​end 110 and a wiring end 120. The bottom of the connector body 100 has a storage slot 170. The bottom of the storage slot 170 is equipped with two sets of rotatable fixing clips 180. The fixing clips 180 include a damping shaft 183 fixed in the storage slot 170. The outer wall of the fixing clips 180 is fitted with a clip arm 181 that can rotate along its axis. The end of the clip arm 181 is fixed with a V-shaped elastic element 182.

[0026] A movable piece 130 is slidably provided on one side of the connector body 100, and a card 140 that can engage with the movable piece 130 is fixed on the other side of the connector body 100. A T-shaped groove 150 for the movable piece 130 to slide laterally is provided on the side wall of the connector body 100. A traction piece 132 is fixed at one end of the movable piece 130, and a plastic elastic element 160 that fits against the upper and lower surfaces of the traction piece 132 is provided on the inner wall of the T-shaped groove 150.

[0027] The connector body 100 has a wire clamping frame 190 for fixing the end of the wire slidably disposed inside, and the end face of the wire clamping frame 190 has a force arm that slides on the outer walls of both sides of the connector body 100.

[0028] It is worth mentioning that: through the stable butt joint of the terminal 120 and the external wire, in the specific operation process of inserting the wire, the force arm needs to be pulled manually to pull the wire pressing frame 190 to move to the side, so as to provide sufficient storage space for the smooth placement of the wire, and then release the force arm. The wire pressing frame 190 automatically restores to the position under the action of the internal elastic mechanism; at this time, the metal sheet embedded in the wire pressing frame 190 is in close contact with the wire to form a reliable electrical connection; when the clamping end 110 is precisely butted with another connector, the metal sheets of both sides are in contact with each other to realize efficient circuit connection between the two groups of wires (the wire pressing frame 190, the force arm and the connector body 100 are all made of non-conductive plastic materials to ensure electrical safety);

[0029] Two groups (or four groups) can be connected side by side to form a connector assembly, which is tightly connected through a standard interface to ensure stable structure; and the two adjacent connector bodies 100 are preferably made of different colors (such as yellow, green, orange and gray), which facilitates quick identification of the connected components of each group of wires, avoids confusion and improves installation and maintenance efficiency;

[0030] In the use process of the connector body 100, the operator needs to apply a rotating external force to the two groups of fixed clamps 180 at the bottom of the connector body 100, so that they are synchronously rotated around the axis of the damping shaft 183 until the two groups of fixed clamps 180 are completely matched with each other, as shown in the drawings. Figure 7 After the fixed clamps 180 are matched, they will quickly realize clamping cooperation with the body sheet metal or other external structure to ensure that the connector body 100 is stably attached to the body sheet metal or external structure, thereby providing reliable connection effect.

[0031] Please refer to Figure 1 and Figure 4 The traction sheet 132 is fixed to the end face of the movable sheet 130 in a trapezoidal shape, and the upper and lower faces of the traction sheet 132 are inclined.

[0032] The surface of the traction sheet 132 extends to the round handle outside the connector body 100, and the inner and outer walls of the connector body 100 are provided with a long straight groove 151 for horizontal movement of the round handle, and the outer surface of the round handle is provided with anti-skid stripes.

[0033] The thickness of the card 140 and the movable sheet 130 is matched with the size of the T-shaped groove 150.

[0034] The outer surface of the movable sheet 130 is provided with two groups of L-shaped outer cards 131 along the length direction thereof, and the two groups of L-shaped outer cards 131 are symmetrically distributed about the transverse axis of the movable sheet 130. The upper and lower faces of the card 140 are provided with two groups of inner lining cards 141 capable of clamping with the L-shaped outer cards 131.

[0035] In the splicing operation of the two connector bodies 100, first, an external force is applied to the round handle, which drives the round handle to move linearly in the horizontal direction inside the long straight slot 151, at this time, the traction piece 132 is driven by the round handle to move together with the movable piece 130, the upper and lower surfaces of the traction piece 132 synchronously extrude the plastic elastic piece 160, forcing the elastic piece to deform to store elastic potential energy; subsequently, the operator needs to accurately and side by side align the two connector bodies 100 to the predetermined position, at the same time, the card 140 is smoothly slid into the T-shaped slot 150 and tightly adheres to the outer surface of the movable piece 130; then, after removing the external force applied to the round handle, the plastic elastic piece 160 releases the stored energy to push the movable piece 130 to return to the original position, at this time, the L-shaped outer card 131 on the outer surface of the movable piece 130 naturally moves to the outside of the inner lining card 141, forming a wrapping structure to tightly wrap the inside, so as to firmly lock the card 140 inside the T-shaped slot 150, finally realizing the reliable locking of the two connector bodies 100.

[0036] The parts not involved in the device are the same as or can be realized by the prior art.

[0037] Although the embodiments of the utility model have been shown and described, the specific embodiments are only an explanation of the utility model, and are not a limitation of the utility model, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner, and the person skilled in the art can make non-creative contribution modifications, replacements and variations of the embodiments according to the needs after reading the specification without departing from the principles and purposes of the utility model, but as long as in the claim range of the utility model, it is protected by the patent law.
