Description

Technical Field

[0001] This utility model belongs to the field of automotive electronic connector technology, and in particular relates to a vehicle-mounted camera connector. Background Technology

[0002] With the upgrading of automotive driver assistance and smart cockpit technologies, the requirements for signal transmission rate and connection reliability of vehicle cameras continue to increase. As the core interface component between the camera and the circuit board, the structural design of the board connector directly affects the system stability.

[0003] Currently, similar connectors in the industry suffer from the following key technical defects:

[0004] Insufficient reliability of coaxial connection: The industry generally adopts the design of board-end male terminal. When the male terminal is connected to the wire-end female terminal, an additional floating mechanism is required to compensate for assembly tolerance. In addition, the exposed contact structure of the male terminal requires a complex wire-end waterproof component (such as multi-layer sealing rings and waterproof sleeves), which not only increases the assembly difficulty and cost, but also makes it easy for the waterproof structure to fail due to aging.

[0005] Poor power contact stability: Power terminals mostly adopt spring-type design. The springs rely on elastic deformation to generate contact force. After long-term use, they are prone to elastic fatigue and deformation failure. Moreover, the point contact mode between the spring and the mating part is easily affected by foreign objects, which can lead to conduction interruption. In the high-frequency vibration environment of automobiles, power loss occurs frequently.

[0006] It is difficult to balance the performance of the outer conductor: Traditional outer conductors are processed in one piece (full die casting or full stamping). Although full die casting has high structural strength, it lacks conductive shielding performance. Although full stamping has good shielding performance, it has weak impact resistance. It is impossible to meet the dual requirements of automobiles for structural strength and signal anti-interference.

[0007] Low assembly efficiency: The spring-loaded power terminals need to be precisely positioned and matched with the plastic body, which can easily cause jamming during assembly; the integrated structure of the outer conductor has strict requirements for installation tolerances, resulting in a low yield rate during mass production.

[0008] Therefore, it is urgent to solve the above-mentioned reliability, assemblability and cost issues through structural optimization, and to develop a high-performance board-end connector suitable for automotive scenarios. Utility Model Content

[0009] The purpose of this invention is to provide a vehicle camera connector that simplifies waterproof design, improves contact reliability, and balances structural and shielding performance.

[0010] To achieve the above objectives, the present invention provides the following technical solution:

[0011] A vehicle-mounted camera connector, comprising:

[0012] The base has a plug-in groove at one end and a first mounting groove extending through the plug-in groove on the base, and a second mounting groove extending through the other end of the base;

[0013] A power terminal, which is fixedly mounted on the base via the first mounting slot;

[0014] A conductor assembly is fixedly mounted on the base via the second mounting groove; the conductor assembly includes a housing conductor, a support member, and a signal terminal arranged in sequence from the outside to the inside.

[0015] Furthermore, the base has an annular protrusion at the second mounting groove, and the outer surface of the outer shell conductor has a stepped surface that fits against the top surface of the protrusion. One end of the outer shell conductor near the stepped surface is riveted and fixed to the bottom end of the protrusion.

[0016] Furthermore, an annular receiving groove is provided on the base at the second mounting groove to accommodate the outward flange generated by riveting the outer shell conductor.

[0017] Furthermore, there are two power terminals, which are arranged side by side in the first mounting slot; a power insulator is embedded in the first mounting slot, and the power terminals are inserted and fixed on the power insulator, with one end of the power terminals bent.

[0018] Furthermore, the power insulator is symmetrically provided with slider portions, and the inner wall of the first mounting groove of the base is provided with corresponding sliding grooves; the power insulator is provided with right-angle grooves for insertion and installation of each power terminal.

[0019] Furthermore, an annular flange is provided on the base outside the conductor assembly to enhance radial support for the conductor assembly.

[0020] Furthermore, the base has symmetrical chamfers at the opening of the insertion slot.

[0021] Furthermore, the insertion slot is a rectangular slot, the power terminal is an L-shaped pin structure, and one end of the signal terminal is bent to form an L-shaped slot structure.

[0022] Furthermore, the top opening of the support member is positioned opposite to the top opening of the signal terminal.

[0023] Furthermore, the base is a die-cast part, and the outer shell conductor is a stamped part.

[0024] Compared with existing technologies, the beneficial effects of this technology are:

[0025] 1. The coaxial structure at the board end is changed from a male terminal to a female terminal structure. The end face of the female terminal can directly form a tight surface seal with the standard sealing ring at the wire end, eliminating the need for multiple layers of waterproof components required by traditional male terminals, reducing the number of waterproof components. At the same time, the surface seal structure is more adaptable to assembly tolerances and improves the waterproof life.

[0026] 2. The power terminals have been changed from spring-loaded to pin-type rigid connection structures. The interference fit between the pin and the right-angle slot of the power insulation component forms a rigid fixation, avoiding the elastic fatigue problem of the spring-loaded design. Compared with the point contact of the spring-loaded design, the line contact mode of the pin increases the contact area and eliminates contact resistance fluctuations, completely solving the power loss problem caused by drops and vibrations.

[0027] 3. The outer conductor adopts a split design of "die-cast base + stamped outer conductor". The die-cast base is integrally formed, which improves the impact resistance; the coaxial stamped outer conductor improves the signal shielding efficiency, which is suitable for the high-definition signal transmission requirements of vehicle cameras.

[0028] 4. The sliding groove structure of the slider and base of the power insulation component, and the plug-in installation of the power terminals shorten the assembly time; the separate outer conductor does not require integrated precision machining, thus improving the yield of mass production.

Detailed Implementation

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0037] like Figures 1 to 4 As shown, this embodiment of the utility model provides a vehicle-mounted camera connector, including:

[0038] The base 1 has a plug groove 11 at one end. The plug groove 11 is a rectangular straight groove with a certain depth. The peripheral wall of the base 1 at the plug groove 11 has a uniform wall thickness to ensure uniform force during plugging. During electrical connection, the plug groove 11 is used as the female terminal of the board end to coaxially insert into the male terminal of the wire end, changing the coaxial structure of the board end from male terminal to female terminal. The end face of the female terminal can directly form a tight surface seal with the standard sealing ring of the wire end, eliminating the need for the multi-layer waterproof components required by the traditional male terminal, reducing the number of waterproof components. At the same time, the surface seal structure has stronger adaptability to assembly tolerances and improves the waterproof life.

[0039] Furthermore, a first mounting groove 12 is provided on the base 1, extending from the bottom to the insertion groove 11. The first mounting groove 12 is located in the middle of the bottom wall of the insertion groove 11 on the base 1, and its opening size is smaller than that of the insertion groove 11. It is used to install the power insulator 4 and the power terminal 2. Specifically, the power insulator 4 is embedded in the first mounting groove 12, and the power terminal 2 is inserted and fixed on the power insulator 4. The fit between the power insulator 4 and the first mounting groove 12 is an interference fit to ensure a tight connection. The power insulator 4 has a certain degree of elasticity and can deform to fit tightly against the base 1 when embedded.

[0040] Specifically, the power insulator 4 is symmetrically provided with sliders 41, which are vertically arranged along the height direction of the power insulator 4. The inner wall of the first mounting groove 12 of the base 1 is provided with a corresponding sliding groove 121, which runs through the entire first mounting groove 12 in the height direction. The arrangement of the slider and the sliding groove 121 can facilitate the power insulator 4 to be quickly aligned with the base 1 for insertion and installation, thereby improving assembly efficiency. The power insulator 4 is provided with a right-angled groove 42 for each power terminal 2 to be inserted and installed. The right-angled groove 42 is adapted to the outer contour of the power terminal 2. After the power terminal 2 is installed in place, it protrudes from the power insulator 4 at a certain height in the insertion groove 11.

[0041] A second mounting groove 13 is provided through the other end of the base 1. The second mounting groove 13 is an annular groove that extends from the upper end to the lower end of the base 1. The second mounting groove 13 is used to install the conductor assembly 3. Specifically, an annular protrusion 131 is provided on the inner wall of the second mounting groove 13 on the base 1. The outer surface of the outer shell conductor 31 is provided with a stepped surface 311 that fits against the top surface of the protrusion 131. One end of the outer shell conductor 31 near the stepped surface 311 is riveted and fixed to the bottom end of the protrusion 131. The protrusion 131 is provided to rivet and fix the outer shell conductor 31. During installation, the outer shell conductor 31 is inserted from the top of the second mounting groove 13 until its stepped surface 311 abuts against the top surface of the protrusion 131. Then, the outer shell conductor 31 is riveted outward 312 and pressed against the lower end surface of the protrusion 131 below the protrusion 131, thereby fixing the outer shell conductor 31 on the base 1.

[0042] Furthermore, an annular receiving groove 132 is provided on the base 1 at the second mounting groove 13 to accommodate the outward flange 312 generated by riveting the outer shell conductor 31, making the overall connection between the conductor assembly 3 and the base 1 more compact and reliable.

[0043] Preferably, a symmetrical chamfer 111 is provided on the base 1 at the opening of the insertion slot 11. The chamfer 111 design facilitates the quick alignment and installation of the wire end connector and the board end connector, improving assembly efficiency. Specifically, the inclination angle of the chamfer 111 is 30 degrees.

[0044] Power terminal 2 is used to transmit DC power. Power terminal 2 is fixedly mounted on base 1 via power insulator 4 in first mounting groove 12. Specifically, there are two power terminals 2, which are arranged side by side on power insulator 4 in first mounting groove 12. One end of power terminal 2 is bent and has an L-shaped pin structure, which is divided into an insertion section and a soldering section. The insertion section is straight and has knurled surface, which is used to interfere with the right angle groove 42 of power insulator 4 to prevent loosening. The soldering section (bent end) extends outward and is perpendicular to the insertion section. The end has a flat surface for soldering to power pads on circuit board.

[0045] The power terminal 2 has been changed from a spring-loaded type to a pin-type hard connection structure. The interference fit between the pin and the right-angle slot 42 of the power insulation component 4 forms a rigid fixation, avoiding the elastic fatigue problem of the spring-loaded design. Compared with the point contact of the spring-loaded type, the line contact mode of the pin increases the contact area and eliminates contact resistance fluctuations, completely solving the power loss problem caused by drops and vibrations.

[0046] Conductor assembly 3 is fixedly mounted on base 1 via second mounting groove 13; conductor assembly 3 includes outer shell conductor 31, support member 32 and signal terminal 33 arranged in sequence from the outside to the inside.

[0047] Signal terminal 33 has one end bent into an L-shaped slot structure. It consists of a vertical section and a horizontal section. The vertical section is a slot structure with two evenly distributed elastic contact flaps on its inner wall. These contact flaps are gold-plated and used for elastic contact with the signal pins of the wire end, compensating for assembly tolerances. The open end of the vertical section has a tapered guide surface for easy insertion of the wire end pins. Near the top of the outer periphery, there is an annular stepped surface that fits against the sealing ring of the wire end plug, forming a surface seal and simplifying the waterproof structure of the wire end. The horizontal section (bent end) extends outwards and has a soldering hole at the end for soldering and fixing to the signal pads on the circuit board.

[0048] The support member 32 is a cylindrical structure with openings at both ends and is made of insulating material. The outer wall of the support member 32 is interference-fitted with the inner wall of the coaxial stamped outer shell conductor 31, and the inner wall is clearance-fitted with the outer wall of the female terminal at the board end, which serves to provide insulation and radial positioning. The top opening of the support member 32 is set opposite to the top opening of the signal terminal 33 to ensure that the male signal pin at the wire end can be inserted smoothly.

[0049] An annular flange 14 is provided on the base 1 protruding from the outside of the conductor assembly 3 to strengthen the radial support of the conductor assembly 3 and prevent it from tilting due to external forces, which would affect its subsequent use.

[0050] In this embodiment, the base 1 is a die-cast part, and the outer shell conductor 31 is a stamped part. The outer conductor adopts a split design of die-cast base 1 and stamped outer shell conductor 31. The die-cast base 1 is integrally formed, which improves the impact resistance. The signal shielding efficiency of the coaxial stamped outer shell conductor 31 is improved, which is suitable for the high-definition signal transmission requirements of vehicle cameras.

[0051] The embodiments described above merely illustrate the implementation of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
