[0019] In this article, the terms "upper, lower, inside, outside" and the like are established based on the positional relationships shown in the drawings. The corresponding positional relationships may also change depending on the drawings, and therefore cannot be understood as absolute limitations on the scope of protection; moreover, relational terms such as "first" and "second" and the like are merely used to distinguish one component from another with the same name, and do not necessarily require or imply any actual relationship or order between these components.

[0020] Example

[0021] like Figure 1-3 As shown, a split wiring harness connector includes a connection terminal 1, a connection tube 2 detachably installed on both sides of the connection terminal 1, and a connection terminal 6 is arranged inside the connection terminal 1; wherein the connection tube 2 at least partially extends into the interior of the connection terminal 1, and an end of the connection tube 2 facing the connection terminal 1 is provided with an external thread, and the connection terminal 1 is provided with an internal thread adapted to the external thread.

[0022] Specifically, the connecting tubes 2 on both sides are used to connect two wire harnesses to be connected. After the two wire harnesses to be connected are connected with the connecting tubes 2, the connecting tubes 2 with the wire harnesses are inserted into the connecting terminal 1, so that the terminals of the wire harnesses on both sides are connected with the connecting terminals 6, thereby connecting the wire harnesses together. In detail, the connecting tubes 2 on both sides are screwed into the connecting terminal 1 by means of a screw connection in which an external thread and an internal thread cooperate. The connection steps of the wire harness are simple, and the connection reliability is high. The connecting terminal 1 and the connecting tube 2 can be disassembled during maintenance. If the connecting tube 2 or the connecting terminal 1 is damaged, it can be replaced separately, and the maintenance difficulty is low.

[0023] Furthermore, a wire fixing piece 3 is provided at one end of the connecting tube 2 away from the connecting terminal 1, and a plurality of elastic pieces 4 are provided at one end of the wire fixing piece 3 facing the connecting terminal 1, and a wire fixing surface 12 is provided at one end of the elastic piece 4 away from the wire fixing piece 3. After the wiring harness is extended into the wire fixing piece 3, the elastic piece 4 is stretched open by the wiring harness. After the wiring harness moves to a preset position, the wire fixing surface 12 of the elastic piece 4 is fixed to the wiring harness, thereby fixing the wiring harness. Preferably, a groove adapted to the wire fixing surface 12 is provided on the wiring harness, which is used to position the extension length of the wiring harness and can enhance the fixing force of the elastic piece 4 on the wiring harness.

[0024] Furthermore, the inner diameter of the end of the wire fixing member 3 away from the connection terminal 1 gradually decreases, and a guide portion 5 is formed; the connection tube 2 is coaxial with the connection terminal 1, and in order to facilitate the coaxial insertion of the wire harness into the connection tube 2, a conical guide portion 5 is provided so that the wire harness can be coaxial with the connection tube 2 and the connection terminal 1 after insertion. And / or, the wire fixing surface 12 is a rough surface, and the rough surface of the wire fixing surface 12 can enhance the connection force between the wire fixing surface 12 and the wire harness.

[0025] Further, a seal is provided between the connecting tube 2 and the connecting terminal 1. The seal is used to ensure the seal between the connecting tube 2 and the connecting terminal 1. Preferably, a seal is also provided between the connecting tube 2 and the wiring harness.

[0026] Furthermore, the sealing member includes an O-ring 11. The O-ring 11 is used to ensure sealing between the connecting pipe 2 and the connecting terminal 1.

[0027] Furthermore, the sealing member includes an inflatable bag 10, and the connection terminal 1 forms an annular groove 9 for accommodating the inflatable bag 10, and an adhesive 8 is provided between the annular groove 9 and the inflatable bag 10. After the connection tube 2 is inserted into the connection terminal 1 by a preset distance, the connection tube 2 will pressurize the inflatable bag 10, so that the inflatable bag 10 is deformed to fill the gap between the connection tube 2 and the connection terminal 1, and even the inflatable bag 10 can fill the gap between the connection tube 2 and the wiring harness after deformation, thereby enhancing the sealing effect of the wiring harness connector, and the adhesive 8 is preferably a resin adhesive.

[0028] The above-mentioned technical features can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
