Description

Technical Field

[0001] This utility model belongs to the field of automotive wiring harness technology, specifically relating to a dustproof protective sleeve for automotive wiring harness connectors. Background Technology

[0002] During use, dust and fine particles can penetrate the interior of automotive wiring harness connectors, accumulating between the metal contacts. This increases contact resistance, leading to unstable signal transmission, increased voltage drop, and even complete circuit breaks, causing various electrical faults and severely impacting the reliability and safety of automotive electronic systems. Therefore, it is necessary to install a dustproof protective cover on the outside of the connector to improve its dustproof performance and ensure the reliability and safety of automotive electronic systems.

[0003] When the two parts of the connector protective sleeve are connected, the contact force applied between them is the key to ensuring the sealing effect. This is because the contact force is applied along the connector axis, compressing the internal elastic sealing ring between the plug and socket housings, causing it to undergo radial and axial elastic deformation. This deformation forces the sealing material to fill and fit all the micro gaps and grooves on the mating surfaces, forming a uniform and continuous contact pressure at the contact interface, blocking external dust, moisture and other contaminants from penetrating along the axial or radial path.

[0004] Currently, when connecting the two parts of a connector, a force needs to be manually applied to the two parts to complete the connection through a snap. Due to limitations in the snap position and ease of installation, the force is limited, making it difficult to achieve the ideal compression deformation of the sealing ring, thus limiting its sealing effect.

[0005] Therefore, there is a need for a dustproof protective sleeve for automotive wiring harness connectors that can improve the contact force between the two parts of the connector and improve the sealing effect to solve the current technical problems. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a dustproof protective sleeve for automotive wiring harness connectors that can enhance the contact force between the two parts of the connector and improve the sealing effect.

[0007] The technical solution of this utility model is as follows: a dustproof protective sleeve for an automotive wiring harness connector, comprising: a male connector and a female connector, each having a wire at one end opposite to the other; a locking mechanism for applying axial abutment force between the male and female connectors on their outer sides; the female connector includes a female connector body, one end of which is fixedly provided with a slot, the slot containing a pin; the male connector includes a male connector body, one end of which is provided with a sealing gasket near the female connector, and the sealing gasket and the male connector body having insertion holes matching the pins; the locking mechanism has a rotating arm, a pull plate, and a locking post; one end of the rotating arm is rotatably connected to the outer side of the male connector body, one end of the pull plate is rotatably connected to the middle of the rotating arm, the other end of the pull plate is locked or released from the male connector body, and the other end of the pull plate has a locking groove matching the locking post; the locking post and the pull plate are correspondingly and fixedly provided on the outer side of the female connector body.

[0008] Furthermore, a locking plate is fixedly provided at the end of the rotating arm, and the locking plate is detachably and fixedly connected to the side of the male head body.

[0009] Furthermore, a U-shaped groove is provided on the locking plate, the opening of the U-shaped groove facing away from the rotating arm, and a stud corresponding to the U-shaped groove is fixedly provided on the side of the male head body, and a nut for locking or releasing the locking plate and the male head body is fitted on the stud.

[0010] Furthermore, the nut is a hand-tightening nut.

[0011] Furthermore, a baffle is concentrically fixed on one end of the locking post away from the slot, and the outer diameter of the baffle is larger than the outer diameter of the locking post.

[0012] Furthermore, two sets of locking mechanisms are symmetrically arranged on both sides of the axis of the male and female heads.

[0013] The beneficial effects of this utility model are:

[0014] (1) In this utility model, when the male head and the female head are connected, one end of the male head body is inserted into the inside of the slot, and one end of the pull plate is fitted onto the outside of the corresponding pin through the slot. Then, the rotating arm is rotated so that it is in the dead position with the pull plate. During the rotation of the rotating arm, the pull plate pulls the female head toward the male head through the pin, compressing the sealing gasket between the male head and the female head, so that the sealing gasket produces radial and axial elastic deformation, blocking external dust, water vapor and other pollutants from penetrating along the axial or radial path.

[0015] (2) The swivel arm and the pull plate form a force-saving lever. When manually installed, a greater abutment force can be applied between the male and female ends to increase the abutment force, so that the sealing ring can achieve ideal compression deformation and improve the sealing effect.

The pad 22, sealing pad 22 and male head body 21 are provided with insertion holes 23 that match the insertion pin 13; the locking mechanism 4 has a rotating arm 42, a pull plate 41 and a locking post 46. One end of the rotating arm 42 is rotatably connected to the outside of the male head body 21, one end of the pull plate 41 is rotatably connected to the middle of the rotating arm 42, the other end of the pull plate 41 is locked or released between the male head body 21, and the other end of the pull plate 41 is provided with a locking groove 48 that matches the locking post 46. The locking post 46 is fixedly installed on the outside of the female head body 11 in correspondence with the pull plate 41.

[0022] In the above embodiment, when the male head 2 is connected to the female head 1, one end of the male head body 21 is inserted into the slot 12, and one end of the pull plate 41 is fitted onto the outside of the corresponding locking post 46 through the locking groove 48. Then, the rotating arm 42 is rotated so that it is at the dead point position with the pull plate 41. During the rotation of the rotating arm 42, the pull plate 41 pulls the female head 1 toward the male head 2 through the locking post 46, compressing the sealing gasket 22 between the male head 2 and the female head 1, so that the sealing gasket 22 produces radial and axial elastic deformation, blocking the penetration path of external dust, water vapor and other pollutants along the axial or radial path; the rotating arm 42 and the pull plate 41 form a force-saving lever, which can apply a greater abutment force between the male head 2 and the female head 1 during manual installation, thereby increasing the abutment force and making the sealing ring achieve ideal compression deformation, thus improving the sealing effect.

[0023] In some embodiments, a locking plate 43 is fixedly provided at the end of the rotating arm 42, and the locking plate 43 is detachably and fixedly connected to the side of the male head body 21; the locking plate 43 and the rotating arm 42 are an integral structure, and the locking plate 43 can increase the area at the end of the rotating arm 42, which facilitates the connection and disassembly between the male head 2 and the female head 1; when the locking plate 43 is fixedly connected to the side of the male head body 21, it can prevent the male head 2 and the female head 1 from loosening or even falling off, and ensure the stability of the connection.

[0024] During disassembly, release the locking plate 43 from the male head body 21, and engage the locking plate 43 to disengage the rotating arm 42 and the pull plate 41 from the dead position. Continue to rotate the rotating arm 42 and pull the end of the pull plate 41 to remove it from the locking post 46 and separate the male head 2 from the female head 1.

[0025] In some embodiments, the locking plate 43 is provided with a U-shaped groove 49, the opening of the U-shaped groove 49 facing away from the rotating arm 42. A stud 44 corresponding to the U-shaped groove 49 is fixedly provided on the side of the male head body 21. A nut 45 for locking or releasing the locking plate 43 and the male head body 21 is installed on the stud 44. When the locking plate 43 is close to the side of the male head body 21, the stud 44 enters the U-shaped groove 49. At this time, the nut 45 is installed on the stud 44 and locked, thereby locking the locking plate 43 and the male head body 21. The locking plate 43 and the male head body 21 can be released by removing the nut 45.

[0026] In some embodiments, nut 45 is a hand-tightening nut, which is convenient for installation and disassembly by hand.

[0027] In some embodiments, a baffle 47 is concentrically fixed on one end of the locking post 46 away from the slot 12. The outer diameter of the baffle 47 is larger than the outer diameter of the locking post 46. The baffle 47 limits the pull plate 41 at the end of the locking post 46, thereby improving the stability of the connection between the pull plate 41 and the locking post 46.

[0028] In some embodiments, two sets of locking mechanisms 4 are symmetrically arranged on both sides of the axis of the male head 2 and the female head 1.
