Description

Expandable automotive boot with sealed terminals

technical field

The invention relates to a component used for automobile assembly, in particular to an expandable protective cover for a vehicle with sealed terminals.

Background technique

China is a big country in the auto industry and a big car consumer. The number of cars is increasing day by day. Cars have become an indispensable tool for the public. In order to meet the special needs of drivers, it is often necessary to upgrade the vehicles during their service life. Such as the installation of anti-theft system, car heating system, panorama system, smart key system and other equipment, this kind of upgrading and transformation process is usually accompanied by the transformation of the electrical part, and new electrical circuits need to be added. These newly added electrical circuits are generally It is necessary to pass through the car body from one space to another space. The existing wiring methods are generally to punch holes in the car body or route along the original car wiring harness. These two methods have certain disadvantages. Holes will inevitably affect the structure of the car body and bring potential safety hazards. When routing along the original car wiring harness, the original car wiring harness is connected to the car body through the matching sealing sleeve. It is necessary to expand the sealing sleeve to pass the new wire through. It is easy to damage the sealing sleeve, which will affect the airtightness of the car body, and the contact between the newly added wiring harness and the original vehicle wiring harness at the sealing sleeve is too close. The electromagnetic interference of the vehicle will affect the electromagnetic compatibility of the whole vehicle. Both methods are time-consuming and labor-intensive in upgrading and transformation, and still need to be solved technically.

The annular boss is covered in the annular film and connected with the annular film. The two ends of the wiring tube are distributed On both sides of the annular film, the wiring pipes on both sides are respectively connected with plugging rods with the outer diameter equal to the inner diameter of the wiring pipes inserted into the ends of the wiring pipes, and the plugging rods are connected with The end of the wiring tube is covered with the bottom column connected by the annular film, the outer end of the bottom column is flush with the outer end of the wiring tube, and the bottom column is connected with an end column that covers the extension rod. end outer diameter.

Further, the extension rod is connected with a blocking cap exposed outside the end column.

Further, one side of the sealing connection ring is provided with an integral metal ring connected thereto, and the metal ring is connected with elastic pieces distributed circumferentially and passing through the other side of the sealing connection ring, and the elastic pieces are connected with buckles.

Further, one side of the sealing connection ring is provided with an integral metal ring connected thereto, the outer edge of the metal ring is connected with circumferentially distributed shrapnel, and the shrapnel is connected with buckles.

The sealing protective sleeve of the present invention is made of rubber and can be used for wiring harnesses of automobile boxes. When the vehicle is assembled, the original car wiring harness is passed through the main wire hole on the core tube, and the main wire hole is sealed and connected with the wire harness by its own elastic force. The connection ring is connected to the vehicle box, the terminal is left in place, and the two sides of the terminal are not connected, which ensures the sealing of the original vehicle. When the user upgrades and needs to add a new line, it can be arranged along the direction of the original vehicle wiring harness. Cut a circular incision at the junction of the terminal posts, then pull out the plug, insert the end of the wire into the port of the wiring tube, and then crimp the port of the wiring tube to make it deform and electrically connect with the wire, so as to realize the passage of the box body and ensure the airtightness of the vehicle , without destroying the car body structure, there is a distance between the crossing point and the original car wiring harness, which can avoid the problems of poor heat dissipation and electromagnetic compatibility caused by the close contact between the new wiring harness and the original car wiring harness at the sealing sleeve, saving time for upgrading and transformation It saves labor, and the wiring tube of the present invention is always in a sealed state when it is not in use, and will not be oxidized and corroded by the environment, so as to ensure the reliability when it is used later.

Detailed ways

Embodiments of the present invention are shown in Figures 1 and 2. The expandable protective cover for vehicles with sealed terminals includes a coaxial core tube 1 made of rubber, a sealing connection ring 2 and a connecting terminal. The core tube is located at the center of the sealing ring, and the core tube It is connected with the sealing connection ring through the annular film 3, the axial center of the core tube is provided with an axial main wire hole 4, the terminal is distributed around the core tube in the circumferential direction, and the terminal is provided with a longitudinal direction consistent with the axial direction of the core tube. Junction pipe 5, the junction pipe is a metal pipe that can be deformed and crimped wires, the junction pipe is provided with a plastic column 6 covering the middle section, the middle section of the plastic column is provided with a radially outwardly protruding annular boss 7, and the annular boss wraps Covered in the annular film and connected with the annular film as a whole, the two ends of the wiring tube are respectively distributed on both sides of the annular film, and the wiring tubes on both sides are respectively connected with plugs, and the plug is provided with an outer diameter and a The plugging rod 8 with the same inner diameter of the wire pipe can be inserted into the port of the wire pipe to achieve sealing. The plugging rod is connected with an extension rod 9 equal to the outer diameter of the wire pipe, which is used for clamping and pulling out the plug, and the end of the wire pipe is coated Due to the rubber bottom column 10 connected by the annular film, the outer end of the bottom column is flush with the outer end of the wiring tube, and the bottom column is connected with an end column 11 covering an extension rod. The outer diameter of the end column is smaller than the outer diameter of the outer end of the wiring tube.
