Description

Technical Field

[0001] This utility model relates to the field of electronic equipment technology, specifically to a waterproof structure for electronic equipment. Background Technology

[0002] With the development of technology, more and more electronic devices are appearing in people's lives. Taking vehicles as an example, in recent years, more and more vehicles have been equipped with in-vehicle cameras. In-vehicle cameras have played a positive role in vehicle control and monitoring of the surrounding environment. However, the operating environment of in-vehicle cameras is complex, posing considerable challenges to their waterproof, shockproof, and reliability performance. The lens of an in-vehicle camera is installed inside the housing, and the camera is connected to the main control unit via a tail wire. Currently, most in-vehicle camera tail wires are inserted into the camera housing and directly connected to the PCBA plug-in inside the housing. Because the camera tail wire is exposed, the wiring harness is easily damaged during daily use. Water is drawn into the housing from the wire core or braided wire, flowing onto the PCBA plug-in and electronic components, resulting in problems such as water ingress into the camera, burning out electronic components, and image display failure. Summary of the Invention

[0003] The purpose of this invention is to provide a waterproof structure for electronic devices and an electronic device having the waterproof structure, so as to solve the problem of electronic devices being damaged by water ingress.

[0004] To achieve the above objectives, the technical solution of this utility model includes:

[0005] A waterproof structure for an electronic device includes a housing and an electrical connection wire passing through the housing. The electrical connection wire is used to electrically connect electrical objects inside and outside the housing. The electrical connection wire includes an inner segment and an outer segment. The outer segment passes through the housing, and the inner segment is located inside the housing. The inner segment and the outer segment are electrically connected through a conductive connection structure. A sealing part is provided inside the housing, and the sealing part encloses the conductive connection structure.

[0006] In one embodiment, the sealing portion is formed by curing a first colloid.

[0007] In one embodiment, a sealing cavity is provided on the inner side of the housing, and the conductive connection structure is disposed in the sealing cavity. The first colloid fills the sealing cavity to encapsulate the conductive connection structure.

[0008] In one embodiment, the conductive connection structure includes an adapter circuit board, wherein the inner segment and the outer segment are electrically connected to the adapter circuit board to form a conductive connection.

[0009] In one embodiment, the inner segment and the outer segment are respectively welded and fixed to the adapter circuit board.

[0010] In one embodiment, the outer side of the housing is provided with an annular mounting flange, the outer segment passes through the mounting flange, and a waterproof reinforcement portion is provided between the outer segment and the inner surface of the mounting flange.

[0011] In one embodiment, the waterproof reinforcement includes an annular protrusion disposed on the outer segment, the annular protrusion forming a tight fit with the inner wall of the mounting flange, and a second colloid filling the space between the inner wall of the mounting flange and the outer segment.

[0012] The technical solution of this utility model also includes: an electronic device, which includes the above-mentioned waterproof structure.

[0013] In one embodiment, the electronic device is a vehicle-mounted camera.

[0014] The beneficial effects of this utility model are:

[0015] 1. This utility model divides the electrical connection wire into inner and outer sections and seals the connection structure of the inner and outer sections by wrapping it with a sealing part. Even if the wire harness is damaged, water from outside the shell will be blocked by the sealing part when it flows along the outer section to the conductive connection structure. This prevents water from entering the inner section of the shell due to the damage of the wire harness along the wire core or braided wire, thereby protecting the electrical connection objects (such as camera body, circuit board, electronic components, etc.) inside the shell.

[0016] 2. The sealing part formed by the curing of the colloid can not only seal the conductive connection structure to block water flow, but also ensure the stable connection between the electrical connection wire and the shell through the connection between the colloid and the side wall of the sealing cavity. This prevents the wire harness from coming out of the shell due to pulling or vibration, thereby ensuring the reliability and service life of electronic devices such as vehicle cameras.

[0023] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0024] See Figure 1 As shown, this utility model discloses a waterproof structure for an electronic device, including a housing 1 and an electrical connection wire 2 passing through the housing 1. The electrical connection wire 2 is used to electrically connect electrical objects inside and outside the housing 1. Electronic devices are composed of electronic components such as integrated circuits, transistors, and electron tubes, and function using electronic technology (including software). Common electronic devices include computers, copiers, projectors, printers, air conditioners, barcode scanners, and monitoring equipment. In this embodiment, the electronic device refers to a vehicle-mounted camera. The electrical connection object inside the housing 1 is the camera body, and the electrical connection object outside the housing 1 is the controller that controls the camera body. Of course, for different electronic devices, the electrical connection object can refer to other electronic components. As long as the electronic device has an electrical connection wire (or wire harness) passing through a housing and connecting electrical objects inside and outside the housing through the electrical connection wire, and also has waterproof requirements, the waterproof structure of this utility model can be used. Further details are omitted here.

[0025] See Figures 1 to 6 As shown, the electrical connection wire 2 includes an inner section 21 and an outer section 22. The outer section 22 passes through the housing 1, and the inner section 21 is located inside the housing 1. The inner section 21 and the outer section 22 are connected by a conductive connection structure 3. A sealing part 4 is provided inside the housing 1, and the sealing part 4 wraps the conductive connection structure 3.

[0026] This utility model achieves a seal between the inner and outer sections by dividing the electrical connection wire 2 into inner and outer sections and wrapping it with a sealing part 4. Even if the wire harness is damaged, water flowing from the outer section to the conductive connection structure 3 will be blocked by the sealing part 4, preventing water from entering the inner section 21 of the housing 1 due to wire harness damage along the wire core or braided wire. This protects the camera body, PCBA plug-in and other electronic components inside the housing 1.

[0027] The conductive connection structure 3 includes a circuit board 30. The inner segment 21 and the outer segment 22 are electrically connected to the circuit board 30 by soldering, thus forming a conductive connection. Soldering and fixing to the circuit board 30 to connect the inner segment 21 and the outer segment 22 provides a more reliable conductive connection between them, thanks to the conductivity of the circuit board 30. Furthermore, soldering is simple and provides a stronger connection. In other embodiments, the inner segment 21 and the outer segment 22 can be fixedly connected to the circuit board 30 by screwing or crimping; alternatively, the conductive core portions of the inner segment 21 and the outer segment 22 can be directly connected to form a conductive connection.

[0028] To improve the stability of the electrical connection wire within the housing 1, a sealing cavity 11 is provided on the inner side of the housing 1. The conductive connection structure 3 is disposed within the sealing cavity 11. A first colloid fills the sealing cavity 11, thereby encapsulating the conductive connection structure 3. After the first colloid cures, it forms a sealing part 4. An annular mounting flange 12 is provided on the outer side of the housing 1. An outer section 22 passes through the mounting flange 12. The outer section 22 has an annular protrusion 221, which forms a tight fit with the inner wall of the mounting flange 12. A second colloid is filled between the outer section 22 and the inner surface of the mounting flange 12. The tight fit between the annular protrusion 221 and the mounting flange 12, together with the cured second colloid, forms a waterproof and reinforcing part 5. Both the first and second colloids are potting compounds, and the specific types of potting compounds can be the same or different. After curing, the potting compounds provide waterproof and sealing functions.

[0029] For the conductive connection structure 3, the potting compound encapsulates it, preventing water from flowing from the external segment 22 to the conductive connection structure 3 after curing, thus forming a reliable waterproof seal. Secondly, the cured potting compound reinforces the connection between the circuit board 30, the internal segment 21, and the external segment 22, preventing the conductive connection structure 3 from loosening due to vibration or pulling, further improving the reliability and lifespan of the vehicle-mounted camera with this waterproof structure. Since the potting compound is filled in the sealed cavity 11 of the housing 1, its cured adhesive properties enhance the connection strength between the housing 1 and the conductive connection structure 3, strengthening the connection between the electrical connection wire 2 and the housing 1, preventing poor contact between the electrical connection wire 2 and the camera body due to vibration or pulling, further improving the reliability and lifespan of the vehicle-mounted camera. The waterproof reinforcement part 5 can form a connection between the outer section 22 and the housing 1, providing pre-fixation for the outer section 22, which is convenient for welding and fixing to the inner section 21 and the circuit board 30. The waterproof reinforcement part 5 can also cooperate with the first adhesive to improve the waterproof effect on the inner and outer sides of the housing 1 and strengthen the connection strength between the electrical connection line 2 and the housing 1.

[0030] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that the remaining undescribed parts are prior art, and that all changes in form and detail made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims fall within the protection scope of the present invention.
