Description

Technical fields:

[0001] This utility model relates to the field of connector product technology, and specifically to an SMB connector with foolproof mounting key positions. Background technology:

[0002] Chinese utility model patent application number 202320575508.9 discloses an adapter connector for a FAKRA adapter, which includes an adapter body. The adapter body includes a shell, and a central guide pin is disposed inside the shell. A ring-shaped crown spring surrounding the central guide pin is fixedly connected to the bottom of the inner wall of the shell. An outer conductor is fixedly connected to the inner wall of the shell above the crown spring. An insulator is fixedly connected to the inner wall of the outer conductor, and the central guide pin is located inside the insulator. In use, the upper end is an SMB female connector, which is plugged into the SMB socket on the camera PCB board. The central guide pin contacts the SMB socket. The insulator provides insulation, and the outer conductor provides conductivity. The lower end is a FAKRA male connector, which connects to the FAKRA female connector on the connection line of the host. The crown spring ensures a tight fit between the two, allowing the host and camera to be connected without disassembling the camera, enabling the camera to work normally. Therefore, it can meet the user's space and performance requirements, avoid the need to replace adapters, reduce costs, improve efficiency, and achieve the effect of improving equipment adaptability.

[0003] However, the outer shell has a symmetrical shape, making it difficult or impossible to visually distinguish it when assembled with the camera back cover. It lacks a foolproof function, which can lead to "reverse assembly"—that is, the hooks on the outer shell face the opposite direction to the preset direction, requiring rework and affecting assembly efficiency. In addition, after the outer shell is assembled with the camera back cover, it cannot achieve a fitting and positioning, which cannot improve the stability of the assembly structure and thus cannot improve product quality.

[0004] In view of the above, the inventors propose the following technical solution. Utility model content:

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide an SMB connector with foolproof mounting key positions.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The SMB connector with anti-foolproof mounting key includes an outer conductor, an insulator disposed within the outer conductor, and a center conductor disposed within the insulator and coaxially distributed with the outer conductor. The outer conductor is mounted on the rear cover of the camera. The outer conductor is also provided with a first mounting key for distinguishing appearance and achieving anti-foolproofing. A second mounting key corresponding to the first mounting key is provided on the rear cover of the camera. After the outer conductor is assembled with the rear cover of the camera, it is positioned by the interlocking of the first mounting key and the second mounting key.

[0007] Furthermore, in the above technical solution, the outer conductor has a radially outwardly extending mounting plate formed in the middle, and the outer edge of the mounting plate is provided with the first mounting key; the camera rear cover is provided with a mounting groove for accommodating the mounting plate, and the inner wall of the mounting groove is provided with the second mounting key.

[0008] Furthermore, in the above technical solution, the mounting plate has four planes arranged in a parallelogram around its periphery, and at least one plane is provided with the first mounting key.

[0009] Furthermore, in the above technical solution, the number of the first installation keys is one, which is set on any one plane; or, the number of the first installation keys is two, which are set on any two planes and are symmetrically or asymmetrically distributed; or, the number of the first installation keys is three, which are set on any three planes and any two of the first installation keys are symmetrically or asymmetrically distributed; or, the number of the first installation keys is four, which are set on four planes and any two of the first installation keys are symmetrically or asymmetrically distributed.

[0010] Furthermore, in the above technical solution, the first mounting key is set as a boss, and the corresponding second mounting key is set as a groove; or, the first mounting key is set as a groove, and the corresponding second mounting key is set as a boss.

[0011] Furthermore, in the above technical solution, the lower end face of the mounting plate is provided with an annular groove, and a sealing ring is embedded in the annular groove. The sealing ring partially protrudes outside the annular groove and contacts the bottom surface of the mounting groove to form a sealed assembly.

[0012] Furthermore, the above technical solution also includes an inner conductor, which is fixed inside the outer conductor and wrapped around the insulator. The outer wall of the inner conductor and the inner wall of the upper end of the outer conductor form a first mating groove. The upper end of the center conductor extends into the inner conductor, and the inner wall of the inner conductor and the outer wall of the upper end of the center conductor form a second mating groove.

[0013] Furthermore, in the above technical solution, a first mating cylinder is formed on the upper part of the outer conductor, and a second mating cylinder is formed on the lower part of the outer conductor. The inner conductor is fixed in the first mating cylinder, and the lower end of the insulator is also embedded in the second mating cylinder. The lower end of the center conductor also passes through the lower end of the insulator to extend into the second mating cylinder. A third mating groove is formed between the inner wall of the second mating cylinder and the outer wall of the lower end of the center conductor. Sealant is also injected into the second mating cylinder to form a sealing block. The sealing block seals the first gap formed between the second mating cylinder and the insulator and the second gap formed between the center conductor and the insulator.

[0014] Furthermore, in the above technical solution, the lower end of the first docking cylinder is provided with a first stepped groove and a second stepped groove located below the first stepped groove; the middle part of the insulator is formed with an outwardly protruding step, and is fixed in the second stepped groove by the step; the lower end of the inner conductor is fixedly assembled with the first stepped groove, and the lower end of the inner conductor is also pressed on the upper end face of the step.

[0016] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: The present invention provides a first mounting key on the outside of the outer conductor, and provides a second mounting key on the camera back cover corresponding to the first mounting key. This enables the SMB connector with mounting key anti-foolproofing to be visually distinguished, realizing the anti-foolproof function, so that the phenomenon of "installing backwards" will not occur when assembling with the camera back cover later, thus improving assembly efficiency; In addition, after the outer conductor is assembled with the camera back cover, the first mounting key and the second mounting key are interlocked and positioned, which can also improve the stability of the assembly structure.

[0027] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0028] See Figures 1-10 As shown, this is an SMB connector with foolproof mounting key positions, which can be used for vehicle camera connections, intelligent assisted driving, etc., and can meet ADAS functions such as APA automatic parking and blind spot monitoring.

[0029] Specifically, the SMB connector with keyless mounting of this utility model includes an outer conductor 1, an insulator 2 disposed within the outer conductor 1, and a center conductor 3 disposed within the insulator 2 and coaxially distributed with the outer conductor 1. The outer conductor 1 is mounted on the rear cover 5 of the camera.

[0030] The main improvements of this invention are as follows: The outer conductor 1 is further provided with a first mounting key 10 for distinguishing appearance and preventing mistaken installation, and a second mounting key 50 corresponding to the first mounting key 10 is provided on the camera back cover 5. After the outer conductor 1 and the camera back cover 5 are assembled, the first mounting key 10 and the second mounting key 50 are mutually engaged and positioned. In other words, this invention provides a first mounting key 10 on the outer conductor 1 and a second mounting key 50 corresponding to the first mounting key 10 on the camera back cover 5, thereby enabling visual differentiation of the SMB connector with mistaken installation key, achieving a mistaken-proof function, so that the "reverse installation" phenomenon will not occur when assembling with the camera back cover 5 later, improving assembly efficiency; in addition, after the outer conductor 1 and the camera back cover 5 are assembled, the mutual engagement and positioning of the first mounting key 10 and the second mounting key 50 also improves the stability of the assembly structure.

[0031] The outer conductor 1 has a radially outwardly extending mounting plate 11 formed in its middle, and the mounting plate 11 is configured with a symmetrical shape. The outer edge of the mounting plate 11 is provided with the first mounting key 10; the rear cover 5 of the camera is provided with a mounting groove 51 for accommodating the mounting plate 11, and the inner wall of the mounting groove 51 is provided with the second mounting key 50. When the mounting plate 11 is inserted into the mounting groove 51, the first mounting key 10 and the second mounting key 50 are engaged and positioned with each other.

[0032] In this embodiment, the mounting plate 11 has four parallelogram-shaped planes 111 on its periphery. These planes 111 are symmetrically distributed in pairs, and at least one plane 111 is provided with the first mounting key 10.

[0033] Combination Figures 9-10 As shown, the number and method of setting the first installation key 10 include at least the following four:

[0034] The first type is: the number of the first installation key 10 is one, which is set on any plane 111.

[0035] The second type is: the number of the first mounting key 10 is two, which are set on any two planes 111 and are distributed symmetrically or asymmetrically.

[0036] The third type is: the number of the first installation key positions 10 is three, which are set on any three planes 111, and any two first installation key positions 10 are symmetrically or asymmetrically distributed.

[0037] The fourth type is: the number of the first installation key positions 10 is four, which are set on four planes 111, and any two first installation key positions 10 are symmetrically or asymmetrically distributed.

[0038] Correspondingly, the second installation key 50 is disposed on the inner wall of the installation slot 51 in a manner that matches the position and number of the first installation key 10.

[0039] In this embodiment, combined with Figure 10 As shown, the first mounting key 10 is configured as a boss, and correspondingly, the second mounting key 50 is configured as a groove; or, combined with Figure 9 As shown, the first mounting key 10 is configured as a groove, and the corresponding second mounting key 50 is configured as a boss.

[0040] To improve the sealing performance of the outer conductor 1 and the camera back cover 5 after assembly, the following design was also made: an annular groove 112 is provided on the lower end face of the mounting plate 11, and a sealing ring 113 is embedded in the annular groove 112. The sealing ring 113 protrudes out of the annular groove 112 and contacts the bottom surface of the mounting groove 51 to form a sealed assembly, which can achieve the function of dustproof and waterproof.

[0041] The present invention also includes an inner conductor 4, which is fixed inside the outer conductor 1 and wrapped around the insulator 2. The outer wall of the inner conductor 4 and the upper inner wall of the outer conductor 1 form a first mating groove 101. The upper end of the center conductor 3 extends into the inner conductor 4, and the inner wall of the inner conductor 4 and the upper outer wall of the center conductor 3 form a second mating groove 401. The first mating groove 101 and the second mating groove 401 are used for mating connectors to be inserted to achieve conduction.

[0042] The following provides a detailed description of the structure of the outer conductor 1 and its assembly structure:

[0043] The upper part of the outer conductor 1 is formed with a first docking cylinder 12, and the lower part of the outer conductor 1 is formed with a second docking cylinder 13. The inner conductor 4 is fixed in the first docking cylinder 12. The lower end of the insulator 2 is also embedded in the second docking cylinder 13, and the lower end of the center conductor 3 also passes through the lower end of the insulator 2 to extend into the second docking cylinder 13. A third docking groove 102 is formed between the inner wall of the second docking cylinder 13 and the outer wall of the lower end of the center conductor 3, which is used to dock and conduct with the connector on the circuit board provided in the rear cover 5 of the camera.

[0044] The second docking cylinder 13 is also filled with sealant to form a sealing block 14, which seals the first gap between the second docking cylinder 13 and the insulator 2 and the second gap between the center conductor 3 and the insulator 2, thereby achieving the purpose of dustproof and waterproof.

[0045] In this embodiment, the lower end of the first docking cylinder 12 is provided with a first stepped groove 121 and a second stepped groove 122 located below the first stepped groove 121; the insulator 2 has an outwardly protruding step 21 formed in the middle, and is fixed in the second stepped groove 122 by the step 21; the lower end of the inner conductor 4 is fixedly assembled with the first stepped groove 121, and the lower end of the inner conductor 4 is also pressed on the upper end surface of the step 21, thereby confining the insulator 2 in the outer conductor 1, improving the stability of the assembly structure, and thus enhancing the product quality.

[0046] The lower periphery of the inner conductor 4 has several protruding tensioning protrusions 41 for embedding and positioning with the first stepped groove 121. When the tensioning protrusions 41 contact the first stepped groove 121, an interference fit is formed to achieve a stable assembly. The lower end of the tensioning protrusions 41 is provided with an inclined surface 411, which guides the tensioning protrusions 41 to enter the first stepped groove 121 more smoothly to complete the assembly. The outer conductor 1 has a snap-fit ​​15 on its periphery.

[0047] The upper surface of the camera rear cover 5 is provided with several positioning posts 501 and several positioning grooves 502.

[0048] In summary, this utility model provides a first mounting key 10 on the outside of the outer conductor 1, and a second mounting key 50 corresponding to the first mounting key 10 on the camera back cover 5. This enables visual differentiation of the SMB connector with foolproof mounting key, achieving a foolproof function and preventing "reverse installation" during later assembly with the camera back cover 5, thus improving assembly efficiency. Furthermore, after the outer conductor 1 is assembled with the camera back cover 5, the first mounting key 10 and the second mounting key 50 interlock and position each other, which also improves the stability of the assembly structure.
