Description

Technical Field

[0001] This utility model relates to the field of automotive component technology, specifically to a connector dust cover. Background Technology

[0002] Connectors, also known as plugs or sockets in China, generally refer to electrical connectors. They are devices that connect two active devices to transmit current or signals.

[0003] A connector is a device that allows the male and female terminals to transmit information or current when they come into contact.

[0004] Automotive component connectors are key components used to connect various electrical and electronic parts in a car; they are also known as automotive plugs.

[0005] However, when the connector is not in use, dust can easily enter the connector from the interface, which can affect the performance of the connector. Therefore, it is advisable to add a dust cover to protect the interface of the connector from dust.

[0006] The existing technology has the following problems:

[0007] In actual use, most existing devices have a separate connection between the dust cover and the connector, which makes the installation and removal of the protective cover more complicated. Furthermore, if the dust cover is not directly connected to the connector, it is easy to lose after the dust cover is removed. Utility Model Content

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This utility model provides a connector dust cover. Through a fixing mechanism, the dust cover is connected to the hinge bracket via a pivot, allowing it to be installed on the connector and preventing loss after disassembly. By flipping the dust cover over the connector top, the clamping block on the dust cover can be inserted into the housing. Rotating the knob then drives a bidirectional lead screw, which in turn moves the threaded plates at both ends closer together under the guidance of a guide rod. This causes the threaded plates to move synchronously with the extension plate and the insertion block, allowing the insertion block to directly insert into the slots on both sides of the clamping block, thus fixing the clamping block and securing the dust cover. The dust cover effectively prevents dust from entering the connector's interior.

[0020] This utility model provides a connector dust cover. Through a positioning mechanism, the dust cover flips open to expose the interior of the connector for connection. A rotating locking plate rotates on the connecting rod, facilitating the separation of the locking slot on the top of the locking plate from the connecting rod, thus eliminating obstruction of the moving plate. Then, under the return effect of the compression spring, the moving plate and the right side of the positioning rod are pushed, allowing the positioning rod to directly insert into the positioning hole, thereby fixing the positioning plate and limiting the dust cover's movement to prevent it from affecting the connector's use. Conversely, pulling the moving plate to the left on the limiting rod separates the positioning rod from the positioning hole, and the locking slot on the locking plate engages with the limiting rod, thus blocking the moving plate. The dust cover can then be flipped open to fit the connector, facilitating dust protection. Attached Figure Description

[0027] The present invention will be further described in detail below with reference to embodiments:

[0028] like Figures 1-5 As shown, this utility model provides a connector dust cover, including a connector 1, a positioning plate 2 fixedly mounted on the top of the connector 1, a connector 3 fixedly mounted on the top of the connector 1, a dust cover 4 movably mounted on the front end of the connector 3, a fixing mechanism 5 on the right end of the positioning plate 2, a hinge seat 6 fixedly mounted on the left end of the dust cover 4, a positioning mechanism 7 on one side of the hinge seat 6, a rubber ring 8 fixedly mounted on the inner side of the dust cover 4, an opening 9 on the fixing mechanism 5, a pressing block 10 fixedly mounted on the right end of the dust cover 4, slots 11 on both the upper and lower ends of the pressing block 10, a hinge frame 12 fixedly mounted on the left end of the positioning plate 2, and a rotating shaft 13 rotatably mounted on the inner side of the upper end of the hinge frame 12.

[0029] The interior of the hinge seat 6 is fixedly sleeved with the outer wall of the middle part of the rotating shaft 13.

[0030] The rubber ring 8 matches the inside of the connector 3 and is movably connected. The rubber ring 8 can improve the dustproof effect of the dust cover 4 on the connector 1.

[0031] In this solution, the dust cover 4 is fixedly connected to the pivot 13 on the hinge frame 12 via the hinge seat 6, forming a rotatable connection structure. This allows the dust cover 4 to be installed on the positioning plate 2, and also prevents the dust cover 4 from accidentally falling off and being lost in frequent use scenarios.

[0032] like Figure 3 As shown, the fixing mechanism 5 includes a housing 51. The bottom end of the housing 51 is fixedly connected to the right end surface of the positioning plate 2. A bidirectional lead screw 52 is rotatably installed inside the right side of the housing 51. Guide rods 53 are fixedly provided on both the front and rear sides of the bidirectional lead screw 52. Threaded plates 54 are slidably installed on both the upper and lower sides of the bidirectional lead screw 52 and the guide rods 53. An extension plate 55 is fixedly provided at one end of the threaded plate 54. Insert blocks 56 are fixedly provided on the opposite sides of the extension plate 55. A knob 57 is fixedly provided on the top of the bidirectional lead screw 52.

[0033] One end of the housing 51 is attached to one side of the connector 3, the top of the bidirectional lead screw 52 extends out of the housing 51, and the through port 9 is opened on the left side of the front end of the housing 51.

[0034] One end of the threaded plate 54 is threaded to the outer wall of the double-acting screw 52. The clamping block 10 can enter the housing 51 through the through port 9. The insert block 56 matches the slot 11 and is movably installed.

[0035] In this design, the clamping block 10 enters the housing 51 through the through-hole 9, and the inserts 56 that are close to each other can be inserted into the slots 11 at the upper and lower ends of the clamping block 10 to fix the clamping block 10. This ensures that the dust cover 4 will not move after it is attached to the connector 3. Conversely, if the inserts 56 are far apart, the dust cover 4 can be opened. The guide rod 53 can limit and guide the threaded plate 54 to improve its smooth movement.

[0036] like Figures 4-5 As shown, the positioning mechanism 7 includes a positioning disk 71. One end of the positioning disk 71 is fixedly installed on the top of the rotating shaft 13. The outer wall of the positioning disk 71 is circular with multiple sets of positioning holes 72 at equal intervals. One end of the hinge frame 12 is fixedly provided with a limiting rod 73. A spring 74 is fixedly sleeved on the top of the limiting rod 73. A moving plate 75 is slidably provided on the outside of the limiting rod 73. A positioning rod 76 is fixedly provided on the right side of the top of the moving plate 75. A side plate 77 is fixedly provided on the rear side of one end of the hinge frame 12. A connecting rod 78 is fixedly provided on one end of the side plate 77. A locking plate 79 is fixedly provided on the top of the connecting rod 78 to limit its rotation. A slot 710 is provided on the top of the locking plate 79. A slider 711 is fixedly provided on the lower end of the moving plate 75. A groove 712 is provided on the upper surface of the left end of the positioning plate 2.

[0037] The top of the spring 74 is fixedly connected to the left side of the movable plate 75, the limiting rod 73 is T-shaped, and the bottom end of the positioning rod 76 is fitted into the positioning hole 72 and is movably installed.

[0038] The bayonet 710 matches the outer wall of the connecting rod 78 and is movably engaged, while the slider 711 is slidably installed between the slider and the groove 712.

[0039] In this solution, when dustproofing of connector 3 is required, the operator simply holds the movable plate 75 and gently pulls it to the left. The movable plate 75 slides to the left on the limiting rod 73, overcoming the resistance of the spring 74, causing the positioning rod 76 to gradually separate from the positioning hole 72. After the positioning rod 76 is completely separated from the positioning hole 72, the clamping plate 79 is rotated again to accurately engage the locking slot 710 on the clamping plate 79 with the limiting rod 73. At this time, the clamping plate 79 can once again block the movable plate 75, preventing it from sliding to the right. After completing this series of operations, the dust cover 4 can be easily flipped over and tightly fitted to connector 3. When the movable plate 75 moves left and right, it can drive the slider 711 to slide synchronously in the slide groove 712, thereby improving the stability of the movable plate 75 during movement.

[0040] The working principle of the connector dust cover will be explained in detail below.

[0041] like Figures 1-5 As shown, when the dust cover is in use and dust protection is required for the connector 3 on the connector 1, the dust cover 4 can be rotated, causing the hinge seat 6 at the bottom of the dust cover 4 to drive the rotating shaft 13 to rotate within the hinge frame 12. This facilitates the dust cover 4 to fit against the top of the connector 3. While fitting, the clamping block 10 at the front end of the dust cover 4 can enter the housing 51 through the through-hole 9. Then, the knob 57 can be rotated, which drives the bidirectional lead screw 52 to rotate. The bidirectional lead screw 52 can drive the threaded plates 54 at the upper and lower ends to move closer to each other under the limiting guidance of the guide rod 53. This allows the threaded plates 54 to drive the extension plate 55 and the insertion block 56 to move synchronously, so that the insertion block 56 can be directly inserted into the slots 11 on the upper and lower sides of the clamping block 10, thereby fixing the clamping block 10 and fixing the dust cover. This allows the dust cover 4 to be used to protect the inside of the connector 3 from dust, preventing dust from entering the connector 3. Internally, the insertion block 56 separates from the slot 11, and then the dust cover 4 can be rotated to move away from the connector 3 so that the connector 1 can be used normally. After the dust cover 4 is moved away from the connector 3, the dust cover 4 can be fixed in a limited position. The operator only needs to rotate the locking plate 79 on the connecting rod 78. As the locking plate 79 rotates, the top locking slot 710 gradually separates from the connecting rod 78, so that the locking plate 79 no longer obstructs the moving plate 75. Under the elastic effect of the compression spring 74, the moving plate 75 and the positioning rod 76 connected to it can be pushed to the right. The positioning rod 76 can be accurately inserted into the corresponding positioning hole 72 on the positioning plate 71. With the insertion of the positioning rod 76, the positioning plate 71 is firmly fixed, thus forming a stable limit on the dust cover 4, preventing it from moving freely and avoiding the movement of the dust cover 4 from affecting its use, while also preventing it from hindering the user's installation and insertion.

[0042] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
