Description
Technical Field
[0001] This utility model relates to the field of board-to-board connector technology, and in particular to a miniaturized high-density board-to-board connector. Background Technology
[0002] With the rapid development of electronic information technology, various electronic devices are constantly evolving towards miniaturization, lightweighting, and high-density integration. From smartphones and tablets to precision medical instruments and industrial control modules, increasingly stringent requirements are being placed on the space utilization and connection reliability of internal components. As a core component for realizing signal transmission and power connection between different circuit boards, the performance of board-to-board connectors directly affects the stability and compactness of the entire electronic system.
[0003] Currently, most traditional connectors do not have a dedicated auxiliary fixing mechanism. They mainly rely on the mating of the male and female ends to achieve connection and fixation. This connection method, which only relies on the mating of the male and female ends, has obvious defects. When the equipment is subjected to external forces such as vibration and impact during operation, the relative displacement or even separation of the male and female ends is very likely to occur, directly causing signal interruption or power transmission failure. Therefore, it needs to be improved. Utility Model Content
[0004] The purpose of this invention is to solve the problems mentioned in the background art and to propose a miniaturized high-density board-to-board connector.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a miniaturized high-density board-to-board connector, comprising a high-density board one, a high-density board two, a female end, a male end, a rectangular sleeve, a fixing rod, a baffle, a sliding plate, a locking rod, a connecting rod, a pull handle, a spring, a positioning sleeve, a cylinder, a positioning rod, and a locking hole. The female end is fixedly installed on the side of high-density board two near high-density board one, the male end is fixedly installed on the side of high-density board one near high-density board two, the rectangular sleeve is fixedly installed on the outside of the male end, and the fixing rod is symmetrically fixedly installed on one side of the rectangular sleeve. The baffle is fixedly installed on the fixing rod. At the end away from the rectangular sleeve, the outer wall of the fixing rod is slidably connected to the slide plate. A locking rod is symmetrically fixedly installed on the side of the slide plate away from the baffle. The connecting rod is fixedly installed on the side of the slide plate away from the locking rod. The pull handle is fixedly installed on the outer wall of the connecting rod at the end away from the slide plate. The spring is sleeved on the outer wall of the fixing rod. A positioning sleeve is symmetrically fixedly installed on the side of high-density board one near high-density board two. A cylinder is symmetrically fixedly installed on the side of high-density board two near high-density board one. The positioning rod is fixedly installed at the end of the cylinder near high-density board one. The locking hole is opened through the outer wall of the positioning rod and the positioning sleeve.
[0006] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, by setting up an auxiliary fixing mechanism consisting of a fixing rod, baffle, sliding plate, locking rod, connecting rod, pull handle, spring, positioning sleeve, cylinder, positioning rod and locking hole, after the male end and female end are connected, the locking rod is driven to insert into the locking hole by the elastic restoring force of the spring to form a reliable mechanical lock. This locking method, with the help of the continuous force of the spring, can effectively resist external forces such as vibration and impact during equipment operation, and completely solves the problem that traditional connectors rely solely on the cooperation of the male and female ends, which easily leads to relative displacement or separation, resulting in signal interruption and power transmission failure, and significantly enhances the connection stability.
[0007] 2. In this utility model, a closed space is formed at the connection between the male and female ends by the cooperation of the rectangular pressure frame, the rectangular groove and the rectangular sealing gasket. The compression of the rectangular sealing gasket by the rectangular pressure frame and the elastic deformation of the rectangular sealing gasket effectively prevent the intrusion of dust, moisture and other impurities. This design makes up for the shortcomings of the sealing performance of traditional connectors, reduces failures caused by the intrusion of impurities, extends the service life of the connector and the entire electronic device, ensures the stability of signal transmission, and is more adaptable to the needs of use in complex environments.

[0010] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0011] Please see Figure 1-5 This utility model provides a technical solution: a miniaturized high-density board to board connector, including a high-density board 1, a high-density board 2, a female end 3, a male end 4, a rectangular sleeve 5, a fixing rod 6, a baffle 7, a sliding plate 8, a locking rod 9, a connecting rod 10, a pull handle 11, a spring 12, a positioning sleeve 13, a cylinder 14, a positioning rod 15, and a locking hole 16. The female end 3 is fixedly installed on the side of the high-density board 2 near the high-density board 1, the male end 4 is fixedly installed on the side of the high-density board 1 near the high-density board 2, the rectangular sleeve 5 is fixedly installed on the outside of the male end 4, the fixing rod 6 is symmetrically fixedly installed on one side of the rectangular sleeve 5, and the baffle 7 is fixedly installed on the far side of the fixing rod 6. At one end of the rectangular sleeve 5, the outer wall of the fixing rod 6 is slidably connected to the slide plate 8. The locking rod 9 is symmetrically fixedly installed on the side of the slide plate 8 away from the baffle 7. The connecting rod 10 is fixedly installed on the side of the slide plate 8 away from the locking rod 9. The handle 11 is fixedly installed on the outer wall of the end of the connecting rod 10 away from the slide plate 8. The spring 12 is sleeved on the outer wall of the fixing rod 6. The positioning sleeve 13 is symmetrically fixedly installed on the side of the high-density board 1 near the high-density board 2. The cylinder 14 is symmetrically fixedly installed on the side of the high-density board 2 near the high-density board 1. The positioning rod 15 is fixedly installed on the end of the cylinder 14 near the high-density board 1. The locking hole 16 is opened through the outer wall of the positioning rod 15 and the positioning sleeve 13.
[0012] By setting up an auxiliary fixing mechanism consisting of a fixing rod 6, a baffle 7, a sliding plate 8, a locking rod 9, a connecting rod 10, a pull handle 11, a spring 12, a positioning sleeve 13, a cylinder 14, a positioning rod 15, and a locking hole 16, after the male end 4 and the female end 3 are connected, the elastic restoring force of the spring 12 drives the locking rod 9 to insert into the locking hole 16, forming a reliable mechanical lock. This locking method, with the continuous force of the spring 12, can effectively resist external forces such as vibration and impact during equipment operation, completely solving the problem that traditional connectors rely solely on the cooperation of the male end 4 and the female end 3, which easily leads to relative displacement or separation, resulting in signal interruption and power transmission failure, and significantly enhancing connection stability.
[0013] like Figure 3 As shown, the positioning rod 15 and the positioning sleeve 13 are slidably connected, and the male end 4 and the female end 3 are slidably connected. The sliding engagement of the positioning rod 15 and the positioning sleeve 13 provides a stable guide trajectory for the docking of the two high-density boards, ensuring that the male end 4 and the female end 3 can accurately approach each other along the preset path, avoiding jamming or offset during the docking process. The sliding connection between the male end 4 and the female end 3 ensures that the two can smoothly complete the insertion and removal action, realizing the effective transmission of signals and power.
[0014] like Figure 3As shown, the locking rod 9 is slidably connected to the locking hole 16, and the connecting rod 10 is slidably connected to the baffle 7. The sliding engagement between the locking rod 9 and the locking hole 16 allows the locking rod 9 to be smoothly inserted into or pulled out of the locking hole 16, ensuring convenient and efficient locking and unlocking operations of the auxiliary fixing mechanism. It also ensures flexible operation when connection or separation is required. The sliding connection between the connecting rod 10 and the baffle 7 provides stable support for the movement of the slide plate 8, preventing the connecting rod 10 from shaking or jamming when driving the slide plate 8, thus ensuring the overall stability of the auxiliary fixing mechanism.
[0015] like Figure 3-4 As shown, one end of the spring 12 is fixedly connected to the slide plate 8, and the other end of the spring 12 is fixedly connected to the baffle 7. The fixed connection allows the spring 12 to deform stably and store elastic potential energy when the slide plate 8 slides.
[0016] like Figure 3 and Figure 5 As shown, a rectangular groove 17 is opened on the side of the female end 3 away from the high-density board 2. A rectangular sealing gasket 18 is slidably connected inside the rectangular groove 17. A rectangular pressure frame 19 is fixedly installed on the side of the rectangular sleeve 5 away from the high-density board 1. Through the cooperation of the rectangular pressure frame 19, the rectangular groove 17 and the rectangular sealing gasket 18, a closed space is formed at the connection between the male end 4 and the female end 3. The compression of the rectangular sealing gasket 18 by the rectangular pressure frame 19 and the elastic deformation of the rectangular sealing gasket 18 effectively prevent dust, moisture and other impurities from entering.
[0017] like Figure 3 and Figure 5 As shown, the rectangular pressure frame 19 and the rectangular groove 17 are slidably connected. The sliding fit ensures that the rectangular pressure frame 19 can be smoothly embedded into the rectangular groove 17 during the docking process.
[0018] The working principle of this embodiment is as follows: During the connection operation, the positioning rod 15 and the positioning sleeve 13 are used to achieve initial guidance. The cylinder 14 on the high-density board 2 drives the positioning rod 15 to align with the positioning sleeve 13 on the high-density board 1. As the two high-density boards approach each other, the positioning rod 15 gradually slides into the positioning sleeve 13. This process can ensure that the male end 4 and the female end 3 are accurately aligned, avoiding insertion and removal difficulties or poor contact caused by misalignment. As the male end 4 and the female end 3 gradually approach and complete their docking, the auxiliary fixing mechanism begins to function. The operator pulls the handle 11, which, through the connecting rod 10, causes the slide plate 8 to slide along the fixing rod 6 away from the rectangular sleeve 5. At this time, the spring 12 is compressed. After the male end 4 is fully inserted into the female end 3, the handle 11 is released, and the elastic restoring force of the spring 12 pushes the slide plate 8 back to its original position. The locking rod 9 on the slide plate 8 then inserts into the locking hole 16 on the outer wall of the positioning rod 15 and the positioning sleeve 13, forming a mechanical lock. This structure maintains the locked state through the continuous force of the spring 12, which can effectively resist external forces such as vibration and impact that may be encountered during equipment operation, prevent relative displacement or separation of the male end 4 and the female end 3, and significantly improve the connection stability. In addition, the sealing and protection mechanism is activated simultaneously. The rectangular sleeve 5 outside the male end 4 moves with the male end 4, and the rectangular pressure frame 19 on one side gradually embeds into the rectangular groove 17 opened in the female end 3, which compresses the rectangular sealing gasket 18 in the rectangular groove 17. Through the tight fit between the rectangular pressure frame 19 and the rectangular groove 17 and the elastic deformation of the rectangular sealing gasket 18, a closed space can be formed at the connection between the male end 4 and the female end 3, which effectively prevents dust, moisture and other impurities from entering, ensuring the stability of signal transmission and the service life of the connector.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
