Each conductor 2 has a wire 21, a crimping part 23 and a stopper 25. The crimping part 23 and the stopper are The return pieces 25 are connected to the open wires 21 in sequence; specifically, each wire 21 has a metal conductor in the center and an outer insulating layer covering the metal conductor. The metal conductor can be composed of multi-core stranded wires. Then, the crimping part 23 is crimped and fixed on the metal conductor and the outer insulating layer respectively, and the backstop part 25 is connected to the crimping part 23.

Furthermore, each of the stoppers 25 has an elastic hook portion 251 and a flat plate portion 252 facing each other. The elastic hook portion 251 and the flat plate portion 252 have a structure that is approximately parallel to each other.

Please refer to Figure 3 again. The terminal positioning member 3 is provided at the front open end 13 and can move between the pre-assembly position (as shown in Figure 1) and the locking position (as shown in Figure 2). The terminal positioning member 3 3 has a main board 31, a plurality of plug-ins 33, a plurality of through holes 35 and a plurality of extension arms 37. The plug-ins 33 are formed on the side of the main board 31 facing the wires 2, and the through holes 35 are formed through the main board. 31 , the extension arms 37 are disposed on the left and right sides of the main board 31 and extend toward the main body 11 .

As shown in the figure, in this embodiment, the plug-ins 33 are arranged parallel to each other in a single row at intervals along the first direction D1, and the conductors 2, the accommodating grooves 14, and the through holes 35 are all the above. They are arranged in the following two rows, that is, they are arranged in parallel in the second direction D2 and sequentially spaced in the first direction D1, and are respectively aligned with the plug-ins 33 in the second direction D2, wherein, in the first direction D1 and the second direction D2 are perpendicular to each other as shown in the figure.

In addition, the main body 11 further has a plurality of chute 17. As shown in Figure 5, the chute 17 is configured with two upper and lower chute 17 on the left and right sides, and the extension arm 37 is correspondingly configured with two chute 17 on the left and right sides. There are two upper and lower extending arms 37. The sliding groove 17 is for the extending arm 37 to pass through. When the terminal positioning member 3 moves between the pre-assembly position and the locking position, the extending arm 37 moves on the sliding groove 17. Slide in groove 17.

Please refer to Figures 6 and 7 together. Preferably, first positioning holes 111 and second positioning holes 112 can be formed on both sides of the body part 11 corresponding to the slide groove 17. The terminal positioning member 3 has a convex Block 38 is formed on the extension arm 37. When the terminal positioning member 3 is in the pre-assembly position, the protrusion 38 engages in the first positioning hole 111. When the terminal positioning member 3 is in the locking position , the bump 38 is engaged with the second positioning hole 112 .

It will be described below that the terminal positioning member 3 is switched from the pre-assembly position to the locking position so that the stopper 25 is positioned and the conductor 2 is fixed to prevent it from coming out. Please refer to FIGS. 8 to 12 , wherein FIGS. 8 and 9 are schematic cross-sectional views of the terminal positioning member 3 in the pre-assembly position, and FIGS. 10 to 12 are schematic cross-sectional views of the terminal positioning member 3 in the locking position.

When the wire 2 is inserted into the receiving groove 14 of the housing 1, the elastic hook 251 will pass through the protrusion 19 inside the housing 1. Because the elastic hook 251 is flexible, it will deform slightly and pass through the protrusion. 19, it can produce a passing feeling during the process, and the flat plate portion 252 is designed to pass smoothly without being pushed against. Since the card slots 15 are also arranged at intervals in the first direction D1, in the initial state after the wires 2 are inserted, the upper and lower adjacent wires 2 are close to each other. At this time, the elastic hook 251 has been reset and can be omitted. It is against the inside of the card slot 15 to provide a basic limiting function during initial assembly to prevent pulling out.

Next, as shown in FIGS. 10 to 12 , the terminal positioning member 3 can be moved from the pre-assembly position to the locking position. At this time, the plug-in 33 extends from the front opening end 13 to the body part 11 to The corresponding stop members 25 are pushed up and down to move away from each other in the second direction D2, so that the elastic hook portion 251 and the flat plate portion 252 of the stop member 25 are partially extended to the adjacent slots. 15 and the main body 11 interfere with each other and are in a locked state.

It should be noted that when the terminal positioning member 3 moves to the locking position, the plug-in 33 pushes the adjacent stop members 25 in the second direction D2 to move away from each other until they extend in the slot 15 . In this locked state, at the same time, the displacement of the stopper 25 will cause the conductors 2 to be aligned with the through holes 35 respectively, as shown in FIG. 10 and FIG. 12 . Thereby, when the electrical connector 1000 of the present invention is further connected to an external connector, the external terminal can enter through the through hole 35 and be electrically connected to the conductor 2 .

It should be noted that each stopper 25 is designed with an elastic hook part 251 and a flat plate part 252. The elastic hook part 251 can provide the basic limiting function during initial assembly as mentioned above, and the flat plate part The portion 252 can provide a larger stopping force in the locked state.

To sum up, the electrical connector of this invention can be used to fix the terminals of double rows of parallel wires, so that the wires are positioned in the correct position and are not easy to fall off, thereby ensuring the reliability and stability between the wire terminals and the connector, making this invention The electrical connectors can comply with specifications in specific fields such as automotive electrical connectors.

The above-mentioned embodiments are only used to illustrate the implementation aspects of the present invention and to explain the technical features of the present invention, and are not intended to limit the scope of protection of the present invention. Any changes or equivalence arrangements that can be easily accomplished by those familiar with this technology fall within the scope claimed by this creation, and the scope of rights protection for this creation shall be subject to the scope of the patent application.
