Description

Technical Field

[0001] The present application relates to the technical field of connectors, and in particular to a quick connector. Background Art

[0002] A quick connector is a wire connection tool used in power systems.

[0003] The quick connector comprises a housing, a receiving groove is provided below the housing, a wire clamp is arranged in the receiving groove, a cover body is rotatably connected to the housing, and the cover body can cover the housing. When the cover body is connected to the housing, the cover body is wrapped outside the housing.

[0004] The connector can be hooked onto the cable with the help of the wire clamp, and the housing is located above the cover. In rainy weather, rainwater can easily flow into the cover through the gap between the housing and the cover, and the water remaining inside the connector can easily corrode the connector, thus shortening the service life of the connector. Summary of the invention

[0005] In order to improve the service life of the connector, the present application provides a quick connector.

[0006] The present application provides a quick connector, which adopts the following technical solution:

[0007] A quick connector comprises a shell, a lower end surface of the shell is provided with a accommodating groove, a bottom wall of the accommodating groove is provided with an accommodating hole, a mounting seat is provided in the accommodating groove, a mounting structure that can be hung on a main cable is provided on the mounting seat, a cover body is rotatably connected to the lower part of the shell, a storage groove for the mounting seat to be inserted is provided on the cover body, a drainage structure is provided on the cover body, the cover body comprises a raised portion, a through hole connected to the storage groove is provided at the bottom of the raised portion, the drainage structure comprises a drainage cover arranged below the raised portion, an operating groove is provided at the upper end of the drainage cover, a spring is provided on the bottom wall of the operating groove, an operating disk that can block the through hole is provided on the side of the spring away from the bottom wall of the operating groove, the spring is in a compressed state, and a drainage hole connected to the operating groove is provided at the bottom of the drainage cover.

[0008] By adopting the above technical solution, when rainwater flows into the cover, the weight on the operating panel increases, thereby causing the operating panel to drop, compressing and deforming the spring, and allowing the water in the cover to flow into the drain cover. The water in the drain cover flows to the outside of the connector through the drain hole, making it difficult for water to remain in the cover, reducing the chance of water corrosion to the connector parts and increasing the service life of the connector; conversely, the operating panel blocks the through hole, making it difficult for air and dust and foreign matter to enter the shell through the drain hole and the through hole.

[0009] Optionally, an operating rod is provided on the bottom wall of the operating groove, an operating tube is provided on the outer sleeve of the operating rod, and the upper end of the operating tube is connected to the lower end surface of the operating panel.

[0010] By adopting the above technical solution, the operating tube sleeve is arranged outside the operating rod, so that the operating tube can only move along the axial direction of the operating tube. Even if the operating panel only moves up and down, it plays a guiding role, making it difficult for the operating panel to move in the horizontal direction after it is lowered, so that the operating panel can quickly block the through hole during the resetting process.

[0011] Optionally, a folding tube is provided on the outer sleeve of the operating tube, one end of the folding tube is fixedly connected to the bottom wall of the operating groove, and the other end of the folding tube is fixedly connected to the operating panel.

[0012] By adopting the above technical solution, the folding tube can protect the parts inside the folding tube, so that the parts inside the folding tube are not easily affected by impurities; when there are impurities in the rainwater, some of the impurities will adhere to the folding tube, but as the water in the cover body enters the operating groove through the through hole, the operating disk is lifted and lowered, causing the folding tube to fold and unfold, loosening the impurities adhered to the folding tube and separating the impurities from the folding tube, thereby achieving an anti-scaling effect.

[0013] Optionally, the bottom wall of the storage slot is provided with a guide slope, and the height of the guide slope gradually increases in a direction away from the bottom wall of the storage slot.

[0014] By adopting the above technical solution, the guide slope has a diversion effect on the water in the storage tank, which makes it easier for the water to enter the operating tank through the through hole and also reduces the amount of rainwater residue in the storage tank.

[0015] Optionally, the upper end of the operating disk is conical.

[0016] By adopting the above technical solution, the water on the operating panel flows down along the upper surface of the operating panel, which accelerates the water to enter the storage tank and prevents water from remaining on the operating panel.

[0017] Optionally, an operating structure connecting the drain cover and the raised portion is provided between the two, and the operating structure includes an operating block provided on the outer wall of the raised portion, and a groove for inserting the operating block is provided in the drain cover.

[0018] By adopting the above technical solution, the drain cover is put on the outside of the protrusion, and the operating block is inserted into the groove, so that the drain cover and the protrusion are not easily separated. At this time, the operating panel blocks the through hole to prevent foreign matter from entering the storage tank through the drain hole and the operating groove.

[0019] Optionally, a clamping structure connecting the cover body and the shell is provided between the two, and the clamping structure includes a clamping rod, which is provided on a side surface of the shell along the width direction, and a clamping slot for inserting the clamping rod is provided on the cover body.

[0020] By adopting the above technical solution, when the card rod is inserted into the card slot, the cover body is connected to the shell, so that the mounting seat is not easily exposed to the outside world, reducing the chance of corrosion of the mounting seat; when the card rod is out of the card slot, the staff can drive the cover body to rotate, making it convenient for the staff to drive the screw on the mounting seat.

[0021] Optionally, a mounting hole is provided on the upper end surface of the mounting seat, and the mounting structure includes a mounting hook arranged above the mounting seat and a mounting rod threadedly connected to the mounting hole, the mounting hook passes through the accommodating hole and extends outside the shell, and a mounting bar is rotatably connected above the mounting rod, and the hook portion of the mounting hook is located on the path of the mounting bar moving along the axial direction of the mounting hole.

[0022] By adopting the above technical solution, the installation rod is driven to rotate, so that the installation rod and the installation bar move toward the hook of the installation hook together, so that the installation bar and the hook of the installation hook clamp the main cable, making it difficult for the connector to rotate around the main cable and at the same time difficult for the connector to move along the length direction of the main cable; the installation bar is set to increase the contact area with the bottom of the main cable, thereby improving the clamping effect of the connector on the main cable.

[0023] Optionally, a protective structure is provided on the shell and is covered outside the mounting structure. The protective structure includes a first protective cover arranged above the shell, the first protective cover is rotatably connected to a second protective cover away from the end face of the shell, and a locking assembly is provided between the shell and the second protective cover to connect the two.

[0024] By adopting the above technical solution, the main cable is placed in the first protective cover, and then the first protective cover and the second protective cover are driven to cover each other, and then the first protective cover and the second protective cover are connected by a locking assembly, so that the first protective cover and the second protective cover are not easy to separate, that is, the connection between the main cable and the connector is realized, so that the connector can be hung on the main cable.

[0025] Optionally, the first protective cover and the second protective cover both extend to both sides of the shell in the width direction, and the locking assembly includes a stop block arranged below the first protective cover, a flexible portion arranged on the side of the second protective cover away from the first protective cover, and a locking plate arranged on one side of the shell in the width direction, a card hole is provided on the upper end surface of the locking plate, a locking block is provided on the side of the flexible portion away from the second protective cover, and a locking hook that can be engaged with the locking plate is provided on one side of the locking block.

[0026] By adopting the above technical solution, after the first protective cover is closed with the second protective cover, the flexible part is passed around the baffle, and then the locking hook is inserted through the card hole so that the locking hook is engaged with the locking plate; when the locking hook is not engaged with the locking plate, the staff can drive the second protective cover to rotate around the first protective cover, which is convenient for the staff to insert the main cable into the first protective cover or take the main cable out of the first protective cover.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. When rainwater flows into the cover, the weight on the operating panel increases, so that the operating panel drops, the spring is compressed and deformed, and the water in the cover flows into the drain cover. The water in the drain cover flows out of the connector through the drain hole, so that it is difficult for water to remain in the cover, reducing the probability of water corrosion on connector parts and prolonging the service life of the connector; on the contrary, the operating panel blocks the through hole, so that air and dust are not easy to enter the shell through the drain hole and through hole;

[0029] 2. The folding tube is provided to protect parts such as springs and operating rods; when there is foreign matter adhering to the folding tube, the folding and unfolding of the folding tube can loosen the foreign matter and make it fall off, thereby increasing the service life of the folding tube.
