The connection between the wire harness and between the wire harness and the electrical parts generally adopts connectors, and the automobile wire harness electrical connector is an important part for connecting each electrical device and electronic equipment of an automobile. Fig. 1, fig. 2 and fig. 3 respectively show the explosion diagram, the three-dimensional assembly diagram and the cross-sectional view of the automotive harness electrical connector of the present invention, and it can be known that the automotive harness electrical connector is composed of a main plastic part and a plurality of terminal assemblies. The main plastic part is provided with a plurality of jacks along the length direction for inserting and fixing the terminal component, thereby realizing the signal transmission function.
In the following, the contents of the present invention will be further described in detail with reference to the specific embodiments, and fig. 4 shows a schematic three-dimensional assembly diagram of the terminal assembly of the present invention, which is mainly composed of the terminal 1 and the metal shell 2. The metal housing 2 is formed by stamping and bending a sheet metal body, and is additionally formed with an accommodating cavity 21. The terminal 1 is inserted into and fixed in the receiving cavity 21 (as shown in fig. 5, 6 and 7). After the terminal assembly is assembled in the automotive wiring harness electrical connector, the metal shell 2 is clamped between the wiring terminal 1 and the inner side wall of the jack, and is fixed with the main plastic part by means of the elastic clamping fins 25 arranged on the metal shell (as shown in fig. 3), so that the phenomenon that the wiring terminal 1 is separated from the main plastic part is effectively prevented, the connection reliability of the wiring terminal and the main plastic part is ensured, and the reliability and the stability of signal transmission are further ensured.
Fig. 8 and 9 respectively show a schematic perspective view of two different viewing angles of the middle connection terminal of the present invention, which is formed by stamping and bending a sheet metal body. The connection terminal 1 is formed by connecting a connection part 11 and a sleeving part 12 in sequence from left to right. The fitting portion 12 is formed by sequentially connecting an axial limiting portion 121, a supporting ring portion 122, and an elastic contact arm portion 123 from left to right. The resilient contact arm portion 123 includes a resilient contact arm 1231. The elastic contact arms 1231 are formed by extending the right side wall of the support ring portion 122 to the right, and the number of the elastic contact arms is set to be plural, and the elastic contact arms are uniformly distributed around the periphery of the support ring portion 122. The support ring portion 122 is a split ring structure, which includes a first butt wall 1221 and a second butt wall 1222, and they are inserted and connected to each other. The first abutting wall 1221 is provided with a limiting notch 12211, and correspondingly, a limiting projection 12221 adapted to the limiting notch 12211 is continuously extended from the second abutting wall 1222. Therefore, in the actual use process of the terminal 1, the stability of the structure of the support ring portion 122 is effectively ensured, the deformation phenomenon caused by tension is prevented, the relative dislocation phenomenon of the elastic contact arms 1231 on the support ring portion is avoided, the reliable contact between the elastic contact arms 1231 and the conductive cores matched with the elastic contact arms is ensured, and the stability and the reliability of signal transmission are further ensured.
In the present embodiment, the number of the elastic contact arms 1231 is set to 4, which are a first elastic contact arm, a second elastic contact arm, a third elastic contact arm and a fourth elastic contact arm, respectively. As a further optimization of the structure design of the terminal 1, the elastic contact arm 123 further includes a first connecting arm 1232 and a second connecting arm 1233. The first connecting arm 1232 is connected between the first elastic contact arm and the second elastic contact arm to form an independent conduction part, and the first elastic contact arm and the second elastic contact arm are supported and leaned against each other in the actual use process. The second connecting arm 1233 is connected between the third elastic contact arm and the fourth elastic contact arm to form another independent conduction part, and the third elastic contact arm and the fourth elastic contact arm are supported and leaned against each other in the actual use process (as shown in fig. 8 and 9).

As can be seen from the above description, in the actual use process, the connection terminal 1 needs to be integrally disposed in the main plastic part with the metal housing 2. In order to ensure the assembling reliability of the terminal 1 and the metal shell 2 and to prevent the terminal 1 from generating the "axial play" phenomenon in the actual use process, the front and rear side walls of the axial limiting portion 121 of the terminal 1 may be symmetrically provided with limiting grooves 1211, and correspondingly, two bending clamping strips 22 (as shown in fig. 4, 5, 7, 8, 9, 10, 11) which are matched with the limiting grooves 1211 extend upwards and symmetrically from the bottom wall of the metal shell 2. When the terminal 1 is placed in position with respect to the metal shell 2, the bending strip 22 is bent by a tool to be embedded and clamped in the limit groove 1211.
The metal shell 2 is preferably a split ring structure in view of reducing manufacturing difficulty and cost. Since it is known that the structural stability of the metal shell 2 itself has a significant influence on the mounting position of the terminal 1, a preferable structure of the metal shell 2 includes a third mating wall 23 and a fourth mating wall 24, which are connected by being inserted into each other. The third abutting wall 23 is provided with a limiting insertion hole 231, and correspondingly, a limiting insertion block 241 (as shown in fig. 4, 5, 6, 10 and 11) adapted to the limiting insertion hole 231 is extended from the fourth abutting wall 24. Therefore, the stability of the structure of the metal shell 2 is effectively ensured, the dislocation phenomenon of the third butting wall 23 relative to the fourth butting wall 24 is avoided, the fixing reliability of the third butting wall and the main plastic part is further ensured, and the axial displacement of the wiring terminal 1 is reduced as much as possible.
