[0032] The following is combined with Figure 2-4 This application is described in further detail.

[0033] The embodiment of the present application discloses a terminal fully enclosed D-SUB connector.

[0034] Reference Figure 2 and Figure 3 A terminal fully enclosed D-SUB connector includes a mounting plate 1 and a pin 11 installed on one side of the mounting plate 1. The pin 11 includes a connecting portion 111 and a bending portion 112. The ends of the connecting portion 111 and the bending portion 112 are perpendicular to each other and are integrally formed. The connecting portion 111 is vertically penetrated on the mounting plate 1 and is fixedly connected to the mounting plate 1. A protective member 2 is provided on the mounting plate 1. A plurality of mutually independent terminal chambers 21 are formed inside the protective member 2. The terminal chamber 21 is an L-shaped structure corresponding to the pin 11. The pin 11 is penetrated in the terminal chamber 21 to prevent external air from contacting the pin 11, thereby improving the stability of the connector during use, reducing the oxidation of the pin 11, and improving the service life of the connector.

[0035] Reference Figure 2 and Figure 3 In this embodiment, the protective member 2 is made of insulating material to ensure the insulation performance of the connector. At the same time, the terminal chamber 21 can be filled with an inert gas or a dryer to further slow down the oxidation of the pin 11.

[0036] Reference Figure 2 and Figure 3 The protective member 2 includes a fixing member 22 and a detachable member 23, and the fixing member 22 is integrally formed and arranged on the mounting plate 1. The detachable member 23 is detachably connected to the fixing member 22, and is matched with the fixing member 22 to form the protective member 2. The fixing member 22 and the detachable member 23 are provided with a threading groove 24. The threading groove 24 on the fixing member 22 and the threading groove 24 on the detachable member 23 are matched to form the terminal chamber 21. The connecting portion 111 is inserted into the threading groove 24 on the fixing member 22, and the bending portion 112 is inserted into the threading groove 24 of the detachable member 23. The fixing member 22 and the detachable member 23 are detachably connected to facilitate the manufacture and processing of the connector.

[0037] Reference Figure 2 and Figure 3 In this embodiment, the pins 11 are arranged in three rows, and the bending portions 112 of the three rows of pins 11 are arranged at intervals in a direction perpendicular to the mounting plate 1, and the lengths of the connecting portions 111 of the three rows of pins 11 are different. The fixing member 22 includes fixing blocks corresponding to the multiple rows of bending portions 112. The multiple fixing blocks are connected to each other to form a stepped structure. The detachable member 23 is also composed of multiple fixing blocks connected to each other to form a stepped structure. The fixing member 22 and the detachable member 23 are matched to form a square block structure.

[0038] Reference Figure 2 and Figure 3, a mounting frame 3 is also provided on the mounting plate 1, and the mounting frame 3 includes two vertical plates 31 arranged in parallel and spaced apart and a horizontal plate 32 arranged between the two vertical plates 31, and the vertical plates 31 are vertically fixedly connected with the horizontal plate 32 to form a U-shaped structure. The orientation of the opening of the mounting frame 3 is the same as the extension direction of the end of the bending portion 112 away from the connecting portion 111, and the fixing member 22 is arranged inside the mounting frame 3 and is integrally formed with the mounting frame 3. A slide groove 44 is provided on the side where the two vertical plates 31 are close to each other, and a sliding member 4 is provided at the position of the slide groove 44 of the two vertical plates 31 on the detachable member 23. The sliding member 4 is a rectangular block structure, and the sliding member 4 is arranged parallel to the length direction of the bending portion 112. The sliding member 4 slides and fits in the slide groove 44 along the length direction of the bending portion 112, and an opening is provided on the side of the slide groove 44 away from the horizontal plate 32. Moving the detachable member 23 in a direction away from the transverse plate 32 can separate the detachable member 23 from the mounting frame 3 , thereby achieving a detachable connection between the detachable member 23 and the fixing member 22 .

[0039] Reference Figure 2 and Figure 3 The sliding member 4 includes a loose portion 41 and a pressing portion 42, wherein the loose portion 41 is located on the side of the pressing portion 42 close to the horizontal plate 32. A gap is set between the side of the loose portion 41 and the side wall of the slide 44 to facilitate the staff to insert the sliding member 4 into the slide 44 when installing the detachable member 23. The side wall of the pressing portion 42 and the side wall of the slide 44 are transitionally matched to improve the stability of the sliding member 4 during the sliding process. A transition portion 43 is set between the loose portion 41 and the pressing portion 42, and the transition portion 43 is a conical structure, the small end of the transition portion 43 is connected to the loose portion 41, and the large end of the transition portion 43 is connected to the pressing portion 42. During the sliding process of the sliding member 4, the side of the transition portion 43 can guide the pressing portion 42 to be inserted into the slide 44, which is convenient for the installation of the detachable member 23.

[0040] Reference Figure 2 and Figure 3 An elastic block 5 is provided on one side of the trajectory line of the sliding member 4 in the length direction, and a slot 51 is provided on the vertical plate 31 at a position corresponding to the elastic block 5. The elastic block 5 is inserted into the slot 51, thereby limiting the sliding of the detachable member 23, improving the stability of the detachable member 23 after being connected to the fixing member 22, and further improving the stability of the connector during use.

[0041] Reference Figure 2 and Figure 3A guide slope 52 is provided on the side of the elastic block 5 close to the horizontal plate 32. The guide slope 52 is inclined from the side close to the horizontal plate 32 to the side away from the horizontal plate 32 along the sliding direction of the sliding member 4, and is away from the detachable member 23. In the process of sliding the detachable member 23 in the direction close to the horizontal plate 32, the guide slope 52 can guide the elastic block 5 to deform in the direction close to the detachable member 23, so as to enter between the two vertical plates 31. When the elastic block 5 corresponds to the card slot 51, the elastic block 5 is restored and inserted into the card slot 51 to limit the sliding of the detachable member 23.

[0042] Reference Figure 3 and Figure 4 , the detachable part 23 is also provided with an insert block 6, and a slot is provided on the fixed part 22 at a position corresponding to the insert block 6, and the insert block 6 is inserted in the slot to limit the movement of the detachable part 23 in a direction perpendicular to the mounting plate 1, further improving the stability of the detachable part 23 after installation. At the same time, when the detachable part 23 is subjected to a force in a direction perpendicular to the mounting plate 1, the insert block 6 can share the force on the sliding part 4, thereby improving the service life of the sliding part 4. A chamfer is provided on the side of the insert block 6 close to the mounting plate 1 to guide the insert block 6 to be inserted into the slot.

[0043] The implementation principle of the fully enclosed D-SUB connector of the present application embodiment is as follows: the pin 11 is enclosed and protected by the protective member 2 to prevent the pin 11 from contacting the air, which reduces the mutual influence between adjacent pins 11 and reduces the oxidation of the pin 11. This improves the stability of the connector during use and increases the service life of the connector.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
