Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of connectors, in particular to a female connector. BACKGROUND

[0002] In the design and manufacture of electronic devices, connectors play a crucial role. They not only need to provide reliable electrical connections, but also need to meet the requirements of device miniaturization and high performance. With the advancement of technology, the market has higher expectations for the performance and efficiency of connectors.

[0003] The existing design of the connector involves multiple component parts, such as a shielding assembly including a lower shielding member and an upper shielding member that cooperate with each other, which brings several manufacturing and economic challenges. First, producing these parts requires multiple molds, which significantly increases the cost of mold manufacturing and maintenance. Second, the complex assembly process of multiple parts not only increases the assembly cost, but also may lead to a decrease in production efficiency. These problems lead to an increase in the overall production cost of the connector and have a negative impact on its market competitiveness. CONTENT OF THE UTILITY MODEL

Specifically, the first insulating member 311 is formed by injection molding. In this application, the first insulating member 311 simultaneously covers both the first mating portion 3121 and the first main body portion 3122. Compared with the prior art, which uses multiple parts to assemble and cover the first mating portion 3121 and the first main body portion 3122, the first insulating member 311 in this application can omit the complex assembly process, reduce assembly costs, and thus improve the assembly efficiency of the female connector and reduce the production cost of the female connector.

[0040] Please see Figure 7 The second terminal assembly 32 includes a connected second insulating member 321 and a plurality of second terminals 322. Each second terminal 322 includes an intersecting second mating portion 3221 and a second body portion 3222. The second mating portion 3221 extends along a first direction M, and the second body portion 3222 extends along a second direction N.

Specifically, the second insulating member 321 is formed by injection molding. In this application, the second insulating member 321 simultaneously covers the second mating portion 3221 and the second body portion 3222. Compared with the prior art, which uses multiple parts to assemble and cover the second mating portion 3221 and the second body portion 3222, the second insulating member 321 of this application can omit the complex assembly process, reduce assembly costs, and thus improve the assembly efficiency of the female connector and reduce the production cost of the female connector.

[0041] Please see Figure 6 and Figure 7 The first insulating member 311 has a limiting portion 3111, and the second insulating member 321 has a limiting mating portion 3211. The limiting mating portion 3211 and the limiting portion 3111 cooperate with each other to fix the first terminal assembly 31 and the second terminal assembly 32. Specifically, the limiting portion 3111 is disposed on the side of the first insulating member 311 away from the first main body portion 3122 in the second direction N. That is, the limiting portion 3111 is disposed on the upper surface of the first insulating member 311. In this embodiment, the limiting portion 3111 is a limiting groove, and the limiting mating portion 3211 is a limiting protrusion. In other embodiments, the limiting portion 3111 may be a limiting protrusion, and the limiting mating portion 3211 may be a limiting groove or a limiting through hole.

[0042] Please see Figures 1-4 The female connector also includes a housing 4. A shielding assembly 1 is disposed inside the housing 4. The outer wall of the shielding assembly 1 is provided with a second protrusion 120, and the inner wall of the housing 4 is provided with a second step 41. The second protrusion 120 and the second step 41 cooperate with each other to lock the shielding assembly 1 inside the housing 4.

[0043] The female connector of this application assembles the first terminal assembly 31 and the second terminal assembly 32 through the limiting part 3111 and the limiting mating part 3211; then the first terminal assembly 31 and the second terminal assembly 32 as a whole extend into the receiving part 21 of the inner housing 2 along the first direction M; then the inner housing 2, the first terminal assembly 31 and the second terminal assembly 32 as a whole extend into the receiving cavity 113 of the main shield 11 along the first direction M from the rear end 112 toward the front end 111, and the inner housing 2 is locked in the main shield 11 by the cooperation of the first protrusion 213 and the first step part 119; then the shield back cover 12 is bent and the main shield 11 and the shield back cover 12 are fixed by the snap-fit ​​part 118 and the snap-fit ​​mating part 123; then the shield assembly 1, the inner housing 2, the first terminal assembly 31 and the second terminal assembly 32 are assembled into the outer housing 4.

[0044] It is worth noting that before the inner housing 2, the first terminal assembly 31 and the second terminal assembly 32 are inserted into the receiving cavity 113 of the main shield 11, the shielding back cover 12 does not cover the rear end 112 of the main shield 11. After the inner housing 2, the first terminal assembly 31 and the second terminal assembly 32 are inserted into the receiving cavity 113, the shielding back cover 12 is bent to cover the rear end 112 of the main shield 11. At this time, the shielding back cover 12 abuts against the side of the terminal assembly 3 away from the inner housing 2 in the first direction M.
