DETAILED DESCRIPTION

[0035] The following will be described in detail below with reference to the accompanying drawings. Figures 1-6 The present application will be further described in detail.

[0036] The embodiment of the present application discloses a dustproof structure of a connector.

[0037] Referring to Figure 1 and Figure 2 , it comprises a dust cover body 1 detachably mounted on the connector, a holding part 11 formed on the dust cover body 1, a dredging channel 2 formed on the side of the dust cover body 1, a limiting assembly 3 arranged in the dredging channel 2, and a locking assembly 4 located on the side of the dust cover body 1, wherein the dust cover body 1 is locked with the connector by the locking assembly 4, which can effectively prevent dust from entering, the holding part 11 facilitates the operator to install and remove the dust cover, the dredging channel 2 is used for guiding the pin needle on the connector, the limiting assembly 3 can limit the pin needle of different specifications, and the dustproof effect of the connector is improved, the pin needle is protected, and the operation is facilitated. The multiple locking structure enhances the dustproof sealing performance, the holding part 11 is designed according to ergonomics and is convenient to operate, and the dredging channel 2 and the limiting assembly 3 ensure the stability of the pin needle.

[0038] Referring to Figure 1As shown, the holding part 11 includes a handle integrally formed on the dust cover body 1, and the surface of the handle is formed with corrugated protrusions. The handle is generally made of plastic material and integrally formed with the dust cover body 1 by injection molding process. The material is light and the cost is low. The corrugated protrusions increase the friction between the hand and the handle, making it convenient for the operator to grip. At the same time, the surface of the handle can also be provided with granular protrusions or grooves and other alternative structures to increase the friction. The shape of the handle can be arc-shaped or linear, so as to adapt to the holding habits of different operators.

[0039] Referring to Figure 2 As shown, the dredging channels 2 are arranged at intervals and are opened on both sides of the dust cover body 1. The length of the dredging channel 2 is greater than the length of the bending structure 31. The dredging channel 2 is usually directly formed on the dust cover body 1 by a mold, and the cross-sectional shape thereof can be circular, square, etc. The dredging channels 2 arranged at intervals can guide multiple pin needles at the same time, thereby improving the work efficiency. The number and interval of the dredging channels 2 can be adjusted according to the distribution of the pin needles on the connector.

[0040] Referring to Figure 6 As shown, the limiting assembly 3 includes the bending structure 31 installed on the side wall of the dredging channel 2. The bending structure 31 located in the dredging channel 2 can be provided as one, two, four or more. The number and arrangement of the bending structure 31 inside can be appropriately adjusted according to different pin needle specifications. Only two example bending structures 31 are assembled in the drawing. The bending structure 31 has a first elastic section 311, a second elastic section 312 and a third elastic section 313, which are connected in sequence. The tail of the bending structure 31 close to the first elastic section 311 is displayed on both sides, which is convenient for guiding the pin needle to be inserted.

The bending structure 31 is generally made of elastic plastic or metal material, such as spring steel, and is installed on the inner wall of the dredging channel 2 by injection molding or stamping process. This three-section elastic structure can adapt to different specifications of pin needles. When the pin needle is inserted into the dredging channel 2, it will contact and be limited by different elastic sections according to its different thickness. If there is no suitable elastic material, a rubber pad or other material with certain elasticity can also be used to replace the bending structure 31. The bending structure 31 located on the side wall of the dredging channel 2 is provided with four bending structures 31, and the width of the bending structure 31 is greater than the thickness of the pin needle, so as to ensure the stable limiting of the pin needle.

[0042] Referring to Figure 3 As shown, the first locking member 41 comprises an elastic buckle 411 rotatably mounted on the dust cover body 1 and a spring 412 mounted between the dust cover body 1 and the elastic buckle 411, the elastic buckle 411 is buckled with a notch provided on the end face of the connector. The elastic buckle 411 is usually made of metal material and has certain elasticity and toughness. The spring 412 provides the power for the buckling and opening of the elastic buckle 411. When the dust cover body 1 is mounted on the connector, the elastic buckle 411 is buckled with the notch on the end face of the connector under the action of the spring 412; when the dust cover body 1 needs to be taken out, the elastic buckle 411 is pressed by external force to make it disengage from the notch. In addition, the buckling structure of the elastic buckle 411 and the notch can be replaced by the cooperation of the buckle and the slot.

[0043] Referring to Figure 4 and Figure 5 As shown, the second locking member 40 comprises a guide rod 401 rotatably mounted on the dust cover body 1, a control knob 402 mounted on the guide rod 401 and a clamping block 402 mounted on the guide rod 401, the side face of the dust cover body 1 is provided with a rotating groove 404 for the rotation of the clamping block 402, the clamping block 402 is located in the region less than 1 / 2 of the circumference of the guide rod 401, when the clamping block 402 rotates towards the inner wall of the rotating groove 404, the side wall of the dust cover body 1 and the inner wall of the connector smoothly slide away, the clamping block 402 is flexibly controlled in the active groove or abuts against the inner wall of the connector, thereby realizing the disengagement and locking of the connector and the dust cover body 1; the clamping block 402 rotates with the guide rod 401, the clamping block 402 faces the inner wall of the connector, the inner wall of the connector is integrally formed with protrusions matched with the clamping block 402, the protrusions on the inner wall of the connector and the clamping block 402 have the same number, and the protrusions and the clamping block 402 are vertically connected.

The position of the notch 5 can be observed to determine the state of the connector and the dust cover body 1. The clamping block 402 can be made of plastic or metal material and is mounted on the guide rod 401 by welding or integral forming.

[0044] Referring to Figure 3As shown, the end face of the dust cover body 1 is provided with a guide groove 6, and a limiting strip 7 is installed in the guide groove 6.
