Description

Technical Field

[0001] This utility model relates to connectors. Specifically, it relates to a female connector that prevents solder from penetrating. Background Technology

[0002] Female header connectors are a type of universal connection device widely used in electronics, electrical appliances and instruments. They are mainly used for current or signal transmission and are usually used with pin header connectors to form board-to-board connections. Their function is to act as a bridge between blocked or isolated circuits, and to undertake the task of current or signal transmission. They are usually used with pin headers or electronic wire harness terminals.

[0003] According to a search, Chinese patent document, publication number CN211879674U, discloses a solder-proof female header connector. By setting a solder-blocking plate and a sealing element, it prevents solder from entering the interior of the female header connector body and causing blockage, making the insertion of the pin header connector and the female header connector smoother. Furthermore, by setting a solder-blocking block, solder blocks between adjacent terminals can be separated, thus avoiding short circuits. In addition, by setting a transverse sliding hole on the inner wall of the socket, and setting a slider and compression spring in the transverse sliding hole, when the pin of the pin header connector is inserted into the socket, the pin will squeeze the pin contact piece and deform it. The first vertical section of the pin contact piece will push the slider inward and compress the compression spring. When the pin is fully inserted, the slider will use the elastic restoring force of the compression spring to make the rubber head abut against the pin contact piece, and the pin contact piece will clamp the pin, thereby improving the connection stability between the pin and the socket, making the connection between the pin header connector and the female header connector more stable and reliable. However, during use, although the solder baffle and seals can reduce the amount of solder entering the connector, gaps inevitably appear between the solder baffle and seals and the connector. This makes it impossible to guarantee that solder will not penetrate into the connector, which can easily cause solder to enter the connector and have an impact. Furthermore, after maintenance, the solder baffle and seals are prone to deformation, which reduces their service life. At the same time, the gaps become larger, the sealing performance decreases, and the structural stability is poor. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a female connector that prevents solder from penetrating, which not only has the advantages of preventing solder penetration but also provides structural reinforcement, improving overall stability and service life, thus solving the aforementioned technical problems.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a female connector that prevents solder from penetrating, comprising a female connector base, a female connector body disposed at the lower end of the inner side of the female connector base, a terminal fixedly mounted on the top side of the female connector body, a first sealing sleeve disposed between the female connector body and the female connector base, a reinforcing plate movably mounted on the top side of the female connector base, a second sealing sleeve being snapped onto the top side of the female connector base, a reinforcing sleeve fixedly mounted on the bottom side of the reinforcing plate, fixing clips fixedly mounted on the left and right sides of the reinforcing plate, and fastening plates fixedly mounted on the left and right sides of the female connector base.

[0008] Preferably, the bottom side of the female connector has an installation cavity, the top side of the inner side of the installation cavity has a first installation groove, the inner side of the first installation groove has a first sealing sleeve installed by snap-fit, the four corners of the top side of the female connector have limit holes respectively, the top side of the female connector has a second installation groove, the inner side of the second installation groove has a second sealing sleeve installed by snap-fit.

[0009] Through the above technical solution, during use, the No. 1 sealing sleeve is conveniently positioned and installed under the action of the No. 1 mounting slot. At the same time, the limiting hole helps to limit the movable rod, improving the stability of the reinforcing plate during movement. Furthermore, the No. 2 mounting slot facilitates the positioning and installation of the No. 2 sealing sleeve.

[0010] Preferably, a limiting block is fixedly installed on the top side of the nut body. The limiting blocks are fixedly installed at the four corners of the top side of the nut body in groups of four. A slot is opened on the bottom side of the first sealing sleeve. The size and shape of the slot are respectively matched with the limiting block.

[0011] Through the above technical solution, during use, the limiting block on the top side of the main body of the nut engages with the slot on the bottom side of the No. 1 sealing sleeve, which helps to limit and reinforce the No. 1 sealing sleeve, thereby preventing the No. 1 sealing sleeve from loosening and reducing the sealing performance.

[0012] Preferably, the bottom side of the second sealing sleeve has a first through hole, and the top side of the second sealing sleeve has a first reinforcing groove and a second reinforcing groove, and the size and shape of the first through hole match the terminal.

[0013] Through the above technical solution, under the action of the No. 1 and No. 2 reinforcement grooves, the reinforcement sleeves can be moved down and locked together, thereby strengthening and limiting them, preventing loosening, and ensuring that the No. 2 sealing sleeve is tightly attached to the terminal, thus improving the sealing effect.

[0014] Preferably, movable rods are fixedly installed at the four corners of the bottom side of the reinforcing plate, the size and shape of the movable rods are matched with the limiting holes, and springs are fixedly installed between the movable rods and the limiting holes.

The size and shape of the positioning sleeve match the second reinforcing groove, and the size and shape of the lower end of the reinforcing sleeve match the first reinforcing groove.

[0017] Through the above technical solution, during the assembly process, the reinforcing plate is pushed down, causing the reinforcing sleeve and the second sealing sleeve to engage with each other. After the fixing clip moves down, it connects and fixes with the reinforcing sleeve, thereby preventing the reinforcing plate and the second sealing sleeve from becoming loose. Moreover, after the lower ends of the positioning sleeve and the reinforcing sleeve engage with the second reinforcing groove and the first reinforcing groove respectively, the stability of the connection position can be effectively improved. At the same time, even if the second sealing sleeve deforms, it can continue to engage and stay close to the terminal, improving the service life of the second sealing sleeve and avoiding waste.

[0019] 1. This utility model, through the use of No. 1 sealing sleeve and No. 2 sealing sleeve, facilitates simultaneous sealing of the side of the connector body near the terminal and the upper end of the terminal, thereby improving the sealing performance of the connector body and preventing solder from entering the connector. Moreover, during use, the limiting block on the top side of the connector body and the slot on the bottom side of the No. 1 sealing sleeve are positioned and engaged, which helps to limit and reinforce the No. 1 sealing sleeve, thereby preventing the No. 1 sealing sleeve from loosening and reducing the sealing performance. Furthermore, after the reinforcing sleeve and the No. 2 sealing sleeve are squeezed and engaged, the No. 2 sealing sleeve is tightly attached to the outside of the terminal and the inside of the No. 2 mounting groove, further improving the overall sealing performance.

[0020] 2. During the assembly process of this utility model, by pushing the reinforcing plate downward, the reinforcing sleeve 7 and the second sealing sleeve are engaged with each other, and the fixing clip is connected and fixed with the reinforcing sleeve after it is moved downward, thereby preventing the reinforcing plate and the second sealing sleeve from becoming loose. Moreover, after the lower ends of the positioning sleeve and the reinforcing sleeve are engaged with the second reinforcing groove and the first reinforcing groove respectively, the stability of the connection position can be effectively improved. At the same time, even if the second sealing sleeve deforms, it can continue to engage and be close to the terminal, thereby improving the service life of the second sealing sleeve and avoiding waste.

[0030] Example 1:

[0031] like Figure 1-7As shown, the present invention provides a female connector that can prevent solder from penetrating, including a female connector base 1, a female connector body 2 provided at the lower end of the inner side of the female connector base 1, a terminal 3 fixedly installed on the top side of the female connector body 2, a first sealing sleeve 4 provided between the female connector body 2 and the female connector base 1, a reinforcing plate 6 movably installed on the top side of the female connector base 1, a second sealing sleeve 5 installed on the top side of the female connector base 1 by snap-fit, a reinforcing sleeve 7 fixedly installed on the bottom side of the reinforcing plate 6, fixing clips 8 fixedly installed on the left and right sides of the reinforcing plate 6 respectively, and fastening plates 9 fixedly installed on the left and right sides of the female connector base 1 respectively.

[0032] Specifically, the bottom side of the mounting base 1 has a mounting cavity 101, and the top side of the inner side of the mounting cavity 101 has a first mounting groove 102. A first sealing sleeve 4 is installed inside the first mounting groove 102 by engagement. Limiting holes 103 are respectively provided at the four corners of the top side of the mounting base 1. A second mounting groove 104 is provided on the top side of the mounting base 1, and a second sealing sleeve 5 is installed inside the second mounting groove 104 by engagement. The advantages are that the first mounting groove 102 facilitates the positioning and installation of the first sealing sleeve 4, while the limiting holes 103 help limit the movement of the movable rod 601, improving the stability of the reinforcing plate 6 during movement. Furthermore, the second mounting groove 104 facilitates the positioning and installation of the second sealing sleeve 5.

[0033] Specifically, limiting blocks 201 are fixedly installed on the top side of the nut body 2. Four limiting blocks 201 are fixedly installed at the four corners of the top side of the nut body 2. A groove 401 is provided on the bottom side of the first sealing sleeve 4, and the size and shape of the groove 401 match the limiting blocks 201. The advantage is that the positioning and engagement of the limiting blocks 201 on the top side of the nut body 2 with the groove 401 on the bottom side of the first sealing sleeve 4 facilitates the limiting and reinforcement of the first sealing sleeve 4, thereby preventing the first sealing sleeve 4 from loosening and reducing its sealing performance.

[0034] Specifically, a first through hole 501 is provided on the bottom side of the second sealing sleeve 5, and a first reinforcing groove 502 and a second reinforcing groove 503 are provided on the top side of the second sealing sleeve 5.

[0038] During use, the use of the first sealing sleeve 4 and the second sealing sleeve 5 facilitates simultaneous sealing of the side of the connector body 2 near the terminal 3 and the upper end of the terminal 3, thereby improving the sealing performance of the connector body and preventing solder from entering the connector. Furthermore, during use, the positioning block 201 on the top side of the connector body 2 engages with the groove 401 on the bottom side of the first sealing sleeve 4, which helps to limit and reinforce the first sealing sleeve 4, preventing it from loosening and reducing sealing performance. Moreover, the reinforcement sleeve 7, after being pressed and engaged with the second sealing sleeve 5, ensures that the second sealing sleeve 5 fits tightly against the outside of the terminal 3. The inner side of the second mounting groove 104 further improves the overall sealing performance. During the assembly process, by pushing the reinforcing plate 6 down, the reinforcing sleeve 7 and the second sealing sleeve 5 are engaged with each other. After the fixing clip 8 moves down, it is connected and fixed with the reinforcing sleeve 7, thereby preventing the reinforcing plate 6 and the second sealing sleeve 5 from becoming loose. Moreover, after the lower ends of the positioning sleeve 701 and the reinforcing sleeve 7 are engaged with the second reinforcing groove 503 and the first reinforcing groove 502 respectively, the stability of the connection position can be effectively improved. At the same time, even if the second sealing sleeve 5 deforms, it can continue to engage and be close to the terminal 3, thereby improving the service life of the second sealing sleeve 5 and avoiding waste.
