Referring to Figures 7 and 8, after the above-mentioned insulated front seat 2 and insulated rear seat 3 are assembled, the insulating back cover 4 needs to be assembled. The insulating back cover 4 is disposed on the lower end surface of the base 31 of the insulating rear seat 3 from the bottom, and a short space 311 is formed on the lower end surface of the base 31 of the insulating rear seat 3 to accommodate the insulating back cover 4. The blank 311 is formed with a latching block 312 on the opposite side walls. The insulating rear cover 4 is formed with a latching 41 corresponding to the two side walls of the latching block 312, and the insulating rear cover 4 is provided with a first terminal. The terminal hole 42 through which the 5 pin 52 passes. After the insulating back cover 4 is assembled at the lower end of the insulating rear seat 3, the pin 52 of the first terminal 5 protrudes just from the terminal hole 42. From heretofore, the insulating front seat 2, the insulated rear seat 3 and the insulating rear cover 4 constitute the terminal block 1 as shown in Figs.

The terminal block 1 needs to be combined with the metal casing 7 to form the final connector. The metal casing 7 has a cavity for accommodating the terminal block 1. The metal casing 7 includes an integrally formed main body casing 71 and an end cover 72 having a cavity for accommodating the front and rear of the terminal block 1, and the end cover 72 is located at the end of the main body casing 71. It is bent downward to cover the rear port of the body cavity of the main body casing 71.

In order to form a stable connection between the terminal block 1 and the metal casing 7, and to prevent the terminal block 1 from being warped up and down, a solid structure is added in the present invention, which is characterized in that an inward bend is formed on both side walls of the metal casing 7. A folding positioning piece is formed on the terminal block 1 with a positioning portion that cooperates with the positioning block, and the terminal block 1 in the metal casing 7 is stabilized by the cooperation of the positioning piece and the positioning portion.

As shown in FIG. 5 and FIG. 6 , the above-mentioned stable structure is as follows: the connecting seat 21 of the insulating front seat 2 has a horizontal upper end surface 211 which is flush with the upper end surface of the lower tongue plate 22, and positioning sockets 212 are formed on both sides of the lower end of the connecting seat 21.

Then, the lower card 74 is bent inwardly so that the lower card 74 just falls into the positioning slot 212 formed on both sides of the connector 21. Thus, the terminal is passed through the upper flap 73 and the lower card 74. The seat 1 is sandwiched in the up and down direction to secure the terminal block 1 in the metal casing 7. Since the warpage of the terminal block 1 is usually formed due to insufficient stability in the up-and-down direction, after the stable structure is adopted, a stable connection is formed between the terminal block 1 and the metal casing 7, and the upper and lower warpage of the terminal block 1 can be avoided. .

As can be seen from the above, when the insulating back cover 4 is assembled, since the insulating back cover 4 is in the form of a plate, which has no part for the user to pinch, it is very inconvenient in the assembly process. An auxiliary structure is added to the insulating back cover 4. As shown in Fig. 9, the insulating back cover 4 in the original state includes a main body 40 and an auxiliary handle 400, and a stress notch 401 is formed between the auxiliary handle 400 and the main body 40 to facilitate separation of the two. A latching 41 is formed on two corresponding sidewalls of the main body 40 of the insulating back cover 4, and a positioning protrusion 43 is formed on the rear end surface of the main body 40, and a terminal hole 42 through which the terminal pin passes is formed on the upper and lower end faces of the main body 40. The auxiliary handle 400 is formed by a side wall of the main body 40 opening the card position 41. The stress notch 401 is located at a position where the main body 40 and the auxiliary handle 400 are combined, and is formed at a position corresponding to the card position 41 on the auxiliary handle 400. There is a gap 402.

The insulating back cover 4 having the above structure is provided with an auxiliary handle 400. In the production assembly process, the auxiliary back cover 400 can be used to fix the insulating back cover 4 to the terminal block 1 more quickly and smoothly, thereby improving production efficiency. At the same time, after the assembly is completed, the auxiliary handle 400 can be separated from the main body 40 by using the stress notch 401 provided on the insulating back cover 400 by using equipment or human power.
