[0023] The housing of a rectangular connector is typically a metal shell, and the connecting terminals usually consist of an insulating block and multiple pins or sockets provided on the insulating block. The insulating block is provided with the aforementioned annular ribs.

[0024] The applicant discovered that some rectangular connectors' connecting terminals only insert into the metal housing from the rear, lacking a limiting structure. Therefore, the connecting terminals can detach or wobble, affecting signal transmission stability. Furthermore, since rectangular connectors are typically installed inside the product being used, with ample space for fixation and protection, no protective mechanism is provided at the rear. Rectangular connectors used in product testing equipment are usually exposed to the external environment, and the rear end of the connector is not effectively protected, making them prone to damage over long-term use. Therefore, the applicant provides a rectangular connector tail accessory installation protection device.

[0025] Please refer to the following: Figures 1 to 4 The present invention provides a description of the rectangular connector tail accessory installation protection device. The rectangular connector tail accessory installation protection device includes a protective shell and a pressure plate 30. One end of the protective shell is a snap-fit ​​end, and the other end has a through hole. The snap-fit ​​end is used to snap onto the tail end of the rectangular connector housing 40, and the through hole allows the wiring to pass through. The protective shell is composed of two half-shells 10 that fasten together. One end of each half-shell 10 is a snap-fit ​​end, and the other end has a half-hole, forming a through hole. The pressure plate 30 is inserted between the housing 40 and the connecting terminal 50 of the rectangular connector. One end abuts against the annular rib 51 of the connecting terminal 50, and the other end abuts against the half-shell 10, preventing the connecting terminal 50 from moving outward.

[0026] Specifically, the via is used to allow the connecting wire to pass through, and it can also hold the connecting wire in place, limiting the range of its swing and effectively ensuring the stability of the connection between the connecting wire and the connecting terminal 50.

[0027] The beneficial effects of the rectangular connector tail accessory installation protection device provided by this utility model are as follows: Compared with the prior art, the rectangular connector tail accessory installation protection device provided by this utility model uses a protective shell formed by two half-shells 10 snapped together to be snapped onto the tail of the rectangular connector, thereby providing protection for the connecting wire at the tail of the rectangular connector and avoiding damage, loosening, poor contact, etc. of the connecting wire. In addition, a pressure plate 30 is inserted between the housing 40 and the connecting terminal 50 of the rectangular connector, so that the pressure plate 30 abuts against the annular rib 51 on the connecting terminal 50, preventing the connecting terminal 50 from loosening or even falling off the housing 40, thus increasing the stability during use.

[0028] like Figure 2 and Figure 3 As shown, in a specific embodiment of the rectangular connector tail accessory installation protection device provided in this utility model, the half-shell 10 includes a cover plate 11, two side baffles 12, a rear baffle 13, and a retaining plate 14.

A half hole is opened on the rear baffle 13. The two side baffles 12 are provided on both sides of the cover plate 11 in the width direction and are connected to the cover plate 11. The retaining plate 14 is provided on the side of the cover plate 11 facing the rectangular connector when in use and is connected to the cover plate 11. The retaining plate 14 is used to be locked in the retaining groove 41 of the housing 40.

[0029] Specifically, during use, the card plate 14 is inserted into the slot 41 of the housing 40 to connect the protective device with the rectangular connector. The side baffle 12 abuts against the side of the connecting terminal 50 in the width direction. The cover plate 11 abuts against the upper and lower sides of the connecting terminal 50 and constrains the swing range of the connecting line through the through hole on the rear baffle 13.

[0030] It should be noted that the two half-shells 10 can be connected together by welding or bonding, or they can be detachably connected together by fasteners 20.

[0032] Furthermore, such as Figure 1 and Figure 2 As shown, in a specific embodiment of the rectangular connector tail accessory installation protection device provided in this utility model embodiment, the half shell 10 includes two fixing lugs 15, which are respectively located on both sides of the width direction of the half shell 10 and connected to the side baffle 12 and the rear baffle 13.

[0033] Specifically, the fixed ear plate 15 is connected to the side baffle 12 at the end opposite to the cover plate 11, and the fixed ear plates 15 on the two half shells 10 are aligned and abut against each other to facilitate the installation of the fasteners 20.

[0034] In one specific embodiment of the rectangular connector tail accessory installation protection device provided in this utility model, the cover plate 11, side baffle 12, rear baffle 13, clamping plate 14 and fixing ear plate 15 are integrally connected.

[0035] Specifically, the half-shell 10 is made in one piece using casting, 3D printing, or machining processes, ensuring good mechanical properties and resistance to damage.

[0036] like Figure 1 and Figure 3 As shown, in a specific embodiment of the rectangular connector tail accessory installation protection device provided in this utility model embodiment, the fastener 20 is a screw, which passes through one of the two opposing fixing ear plates 15 and is screwed to the other fixing ear plate 15.

[0037] It should be noted that the fixing hole on one half-shell 10 is a smooth hole, while the fixing hole on the other half-shell 10 is a threaded hole. The screw passes through the smooth hole and is screwed into the threaded hole.

[0038] In addition, the fastener 20 can also be a bolt or a nut, in which case the fixing holes on both half-shells 10 are smooth holes. The bolt passes through the smooth holes on the two half-shells 10 and connects with the nut to fix the two half-shells 10 together.

[0039] like Figure 2 and Figure 4 As shown, in a specific embodiment of the rectangular connector tail accessory installation protection device provided in this utility model embodiment, there are two pressure plates 30. The two pressure plates 30 are respectively inserted on both sides of the connecting terminal 50 along the width direction to clamp the connecting terminal 50, so as to prevent the connecting terminal 50 from shaking left and right (i.e. along the width direction) inside the housing 40.

[0040] like Figure 4 As shown, in a specific embodiment of the rectangular connector tail accessory installation protection device provided in this utility model embodiment, the pressure plate 30 is integrally provided with a limiting step 31. In use, one side of the limiting step 31 abuts against the tail of the housing 40, and the other side abuts against the half-shell 10.

[0041] It should be noted that the limiting step 31 can effectively limit the depth of the pressure plate 30 inserted into the housing 40, avoiding excessive pushing of the connecting terminal 50, and at the same time facilitating the removal of the pressure plate 30. The above description is only a preferred embodiment of this utility model and is not intended to limit this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
