Description

Technical Field

[0001] The utility model relates to the technical field of electronic connectors, and more specifically to a connector shell with a dustproof function. Background Art

[0002] Most of the existing electronic connectors are exposed to the outside when in use. When used in places with a lot of dust, dust can easily enter the inside of the electronic connector, affecting the normal use of the electronic connector. When the dustproof mechanism of the prior art is used, most of them are placed in the dustproof mechanism to play a role in dust shielding. However, due to the different lengths of electronic connectors, when some electronic connectors are installed with the dustproof mechanism, the external terminal connection ports of the electronic connectors are easily exposed to the outside, thereby failing to achieve the dustproof effect.

[0003] In view of the above problem, regarding the technical problem that the external terminal connection ports of some electronic connectors are easily exposed to the outside when they are installed with dustproof mechanisms due to the different lengths of electronic connectors, after a lot of searching, a dustproof mechanism of an electronic connector with patent number CN216055417U was found, which includes a dustproof outer frame, a connector body, a movable frame, a dust shielding plate and an auxiliary dust suction device. The upper surface of the dustproof outer frame is slidably connected to the movable frame through a connecting groove, and the four corners of the lower surface of the movable frame are fixedly connected to connecting blocks, and the lower end of the connecting block is fixedly connected to The movable ring is connected to the upper surface of the movable ring, a rotating screw is arranged through the middle of the movable ring, one end of the rotating screw is rotatably connected to the inner side of the dust-proof outer frame, the other end of the rotating screw is transmission-connected to a micro motor, and the micro motor is fixedly connected to the inner surface of the dust-proof outer frame, and the two adjacent sides of the movable ring are respectively provided with an adjusting screw ring 1 and an adjusting screw ring 2, and the adjusting screw ring 1 and the adjusting screw ring 2 are threadedly connected to the outer surface of the rotating screw, the upper surface of the movable frame is fixedly connected to a connecting plate, and the outer surface of the connecting plate is fixedly connected to a dust shielding plate; however, the technical solution provided by the patent still has the following problems:

[0004] (1) The device is only provided with a dust shield at the top of the dust-proof outer frame, and no dust-proof device is provided at the bottom, so that when the electronic connector is in use, dust can easily enter the inside of the electronic connector from the bottom, affecting the normal use of the electronic connector;

[0005] (2) The distance between the ash inlet and ash outlet of the auxiliary ash suction device in the device is too close, and the dust discharged from the ash outlet can easily enter the ash inlet again, which greatly reduces the working efficiency of the auxiliary ash suction device.

The dustproof function of the connector shell 102 is shown in FIG1 . The dustproof function of the connector shell 102 is shown in FIG1 . The dustproof function of the connector shell 102 is shown in FIG1 . The dustproof function of the connector shell 102 is shown in FIG1 .

[0029] In the embodiment of the utility model, a fixing block 103 is provided at the front of the left and right inner walls of the fixing shell 101 for installing the connector body, rectangular sliding grooves are opened on both sides of the center of the top inner wall and the bottom inner wall of the fixing shell 101, and a rectangular installation groove is opened in the center of the top inner wall of the fixing shell 101.

[0030] In the embodiment of the utility model, metal strips 105 are arranged in the rectangular slide grooves opened on the top inner wall and the bottom inner wall of the fixed shell 101. The metal strips 105 are arranged in a "U" shape, and the metal strips 105 arranged in the rectangular slide groove of the top inner wall are opened downward, and the metal strips 105 arranged in the rectangular groove of the bottom inner wall are opened upward. The "U"-shaped metal strips 105 can reduce the friction between the dust shielding shell 102 when they slide in the fixed shell 101, so that the movement of the dust shielding shell 102 is smoother.

[0031] In the embodiment of the utility model, a rectangular through groove is provided on the side wall of the dust shielding shell 102, and a fixing block 103 on the inner wall of the fixed shell 101 passes through the rectangular through groove and is fixedly installed with the connector body. At the same time, the fixing block 103 also plays a role in supporting the dust shielding shell 102. Slide rods 104 are provided on both sides of the center of the top and bottom ends of the dust shielding shell 102. The slide rods 104 cooperate with the metal strip 105 arranged in a "U" shape to make the front and rear sliding of the dust shielding shell 102 smoother. A stop block 107 is provided on the front side of the top of the dust shielding shell 102. The stop block 107 can prevent the dust shielding shell 102 from completely sliding into the interior of the fixed shell 101, and a rectangular limit groove is provided at the center of the top of the dust shielding shell 102.

[0032] In the embodiment of the utility model, a rubber strip 106 is arranged in the rectangular limiting groove at the top center of the dust shielding shell 102. The rubber strip 106 is arranged in a "U" shape and is directed upward.

[0033] In the embodiment of the utility model, the limiter 3 includes a block 301, a threaded rod 302; a threaded barrel 303 and a knob 304, wherein the block 301 is made of rubber, and vertical anti-slip stripes are arranged on the left and right side walls of the block 301, a threaded rod 302 is fixedly installed on the top of the block 301, the threaded rod 302 is threadedly installed in the threaded barrel 303, and the threaded rod 302 is installed through the top of the fixed shell 101, and a knob 304 is fixedly installed on the top of the threaded barrel 303, and the knob 304 is arranged in a cross shape;

[0034] The card block 301 is arranged at the front part of the rectangular installation groove opened on the top inner wall of the fixed shell 101. At the same time, the width of the card block 301 matches the width of the "U"-shaped groove of the rubber strip 106. When the dust shielding shell 102 is slid to the specified position, the card block 301 can be moved downward by turning the knob 304 until the card block 301 is stuck in the "U"-shaped groove of the rubber strip 106. At this time, the friction between the card block 301 made of rubber and with vertical anti-slip stripes on both side walls and the rubber strip 106 is extremely large, which can prevent the dust shielding shell 102 from retracting.

[0035] In the embodiment of the utility model, a micro fan is provided in the auxiliary dustproof device 2. The micro fan can inhale air from the outside and transport the air to the front end of the fixed shell 101 and the dust shielding shell 102, and then blow the air out from the gap between the outer shell 1 and the connector. An air duct is formed between the gap between the outer shell 1 and the connector to further prevent dust from entering the connector and enhance the dustproof effect of the outer shell 1. A dustproof net is provided at the rear end of the auxiliary dustproof device 2 to prevent dust from entering the auxiliary dustproof device 2.
