Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and more specifically, to a board-end male coaxial connector that ensures stable signal transmission. Background Technology

[0002] In the field of automotive component technology, connectors play a crucial role as key components for signal transmission. They not only need to ensure stable signal transmission but also maintain high reliability and durability in various harsh environments. However, existing connector designs often face a common problem during use—they are prone to loosening.

[0003] Such loosening issues can be caused by a variety of factors, including vibration, temperature changes, and material aging. Once a connector becomes loose, it leads to unstable signal transmission, which can cause a series of problems such as poor contact and signal interruption. These problems not only affect the normal operation of the vehicle but can also pose a serious threat to driving safety. For example, in critical control systems, if a loose connector causes a signal interruption, it may lead to loss of vehicle control or inability to respond to driver commands.

[0004] Therefore, to address this issue, the field has been seeking a connector design that can guarantee stable signal transmission. This design needs to effectively prevent loosening and ensure a tight mating fit under various harsh environments, thereby guaranteeing stable signal transmission. Utility Model Content

[0022] 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 protection scope of the present utility model.

[0023] This utility model provides a board-end male coaxial connector that ensures stable signal transmission, such as... Figure 1-Figure 5 As shown, the device includes a housing 1, an outer conductor 2 installed at one end of the housing 1, an insulator 3 inside the outer conductor 2, a plug 21 installed at one end of the outer conductor 2, a socket 11 at the end of the housing 1 near the outer conductor 2, the socket 11 and the plug 21 being inserted into each other, an opening at the bottom of the housing 1, a buckle 5 installed in the opening, slots 51 on both sides of the inner wall of the buckle 5, and slots 212 on both sides of the outer wall of the plug 21, the top of the buckle 5 extending into the interior of the housing 1 and engaging with the slots 212, a plurality of locking protrusions 24 in the slots 212, and drive components installed on both sides of the locking protrusions 24 and the interior of the outer conductor 2, the drive components rotating via a knob 23 to extend and retract the locking protrusions 24, thereby engaging or disengaging with the slots 51, and a protective sleeve 22 installed on the outer side of the plug 21 at one end of the center needle 4 to protect the needle tip of the center needle 4.

[0024] In this embodiment, a center pin 4 is installed on the inner side of the insulator 3.

[0025] Specifically, a positioning block 12 is installed on the top inner side of the socket 11, and a positioning groove 211 is provided on the top of the plug 21. The positioning block 12 is adapted to the positioning groove 211 to ensure the precise positioning of the plug 21 when it is inserted into the socket 11.

[0026] Furthermore, the inner wall of the slot 212 is provided with an opening, and the locking protrusion 24 slides in cooperation with the opening to facilitate the extension and retraction of the locking protrusion 24.

[0027] Furthermore, the knob 23 is located on top of the outer conductor 2. The drive assembly includes an L-shaped movable part 25. A rack 251 is mounted on the outer wall of one end of the movable part 25. A drive gear 26 is provided on the outer side of the rack 251. The knob 23 is connected to the shaft of the drive gear 26 through a connecting rod. The drive gear 26 meshes with the rack 251. The other end of the movable part 25 is connected to the locking protrusion 24. By rotating the knob 23, the movable part 25 is moved, thereby realizing the extension and retraction of the locking protrusion 24.

[0028] Furthermore, the insert 21 has an inner cavity 213, and a strip-shaped opening 27 is provided on one side of the inner cavity 213. The movable part 25 slides with the strip-shaped opening 27, so that the movable part 25 moves stably and will not deviate.

[0029] Furthermore, several positioning plugs are installed at the bottom of the outer conductor 2 to facilitate the connection and cooperation between the outer conductor 2 and external equipment.

[0030] When using the board-end male coaxial connector of this utility model that ensures stable signal transmission, first insert the plug 21 of the outer conductor 2 into the socket 11 of the outer shell 1, and install the buckle 5 to achieve initial mating. During this process, the positioning block 12 at the top of the socket 11 will insert into the positioning groove 211 at the top of the plug 21 to ensure the precise positioning of the plug 21 within the socket 11.

[0031] Next, by rotating the knob 23 on the top of the housing 1, the drive gear 26 is driven to rotate. The drive gear 26 meshes with the rack 251 at one end of the movable part 25, thereby converting the rotational motion into linear motion, pushing the movable part 25 to slide within the slot 27 of the insert 21.

[0032] The other end of the movable part 25 is connected to the locking protrusion 24. Therefore, as the movable part 25 slides, the locking protrusion 24 will also extend and retract within the slot 212. When the locking protrusion 24 extends, it will engage with the slots 51 on both sides of the buckle 5, achieving a tight engagement between the buckle 5 and the slot 212, thereby further locking the position of the insert block 21 and the insert 11 and preventing loosening.

[0033] When it is necessary to disassemble the connector, simply rotate the knob 23 in the opposite direction to retract the locking protrusions 24, causing them to separate from the bayonet 51. Then remove the clip 5 to easily pull out the plug 21 and complete the disassembly process.

[0034] In addition, several positioning plugs are installed at the bottom of the outer conductor 2 to facilitate plugging and mating with external equipment, further enhancing the stability and reliability of the connector.

[0035] In summary, the board-end male coaxial connector of this utility model, which ensures stable signal transmission, achieves a tight mating fit and a reliable locking mechanism through its unique design and innovative structure, effectively preventing loosening and ensuring stable signal transmission.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
