Description

Technical Field

[0001] The invention belongs to the technical field of connectors, and in particular is a small-pitch double-row foamed anti-leakage waterproof connector device with a blocking secondary lock. Background Art

[0002] Connectors are a type of component that our electronic engineering technicians often come into contact with. Its function is very simple: to build a bridge of communication between blocked or isolated circuits in the circuit, so that the current can flow and the circuit can achieve the predetermined function. Connectors are indispensable components in electronic devices. If you observe along the path where the current flows, you will always find one or more connectors. The form and structure of connectors are ever-changing. There are various forms of connectors depending on the application object, frequency, power, application environment, etc. For example, the connectors used for lighting on the court are very different from the connectors for hard drives and the connectors for igniting rockets. But no matter what kind of connector, it is necessary to ensure that the current flows smoothly, continuously and reliably.

[0003] However, traditional connectors have many problems in actual use!

[0004] First of all, the male end of the traditional connector is a single locking terminal that cooperates with the male and female end bodies. The locking method is a relatively simple single locking method. When the terminal is inserted into the male and female end bodies, the locking structure on the outside of the terminal relies on external force to squeeze into the male and female end bodies. During the removal process, the terminal locking structure and the male and female end bodies are damaged, resulting in poor fixing effect between the terminal and the male and female ends, unstable connection, and easy detachment from each other, which is not conducive to the conductive stability of the connector.

[0005] Secondly, the traditional connector connection and cardboard installation method adopts the wing-type installation method, but it has no sealing function. During the foaming process, it is necessary to add a soft sheath at the back to wrap the outer adhesive tape to prevent leakage. The process is troublesome and the reliability is not very good. There is glue leakage during foaming, and the operation is more troublesome.

[0006] Moreover, when using traditional connectors, when the adjacent holes at the male and female ends are in the same humid space and become damp and form water flow, the connector will be at risk of short circuit because it has no waterproof function.

[0007] In addition, when the male and female ends of the traditional connector are fixed by external hooks and locks, the external hooks will not rebound after being pressed multiple times, resulting in poor fixing effect of the male and female ends and unstable connection.

[0008] Based on this, it is urgent to design a small-pitch double-row foamed anti-leakage waterproof connector device with a blocking secondary lock to solve the above problems. Summary of the invention

[0080] In a possible implementation manner, the male end locking piece 1.2 is further provided with a male end locking piece conical handle 1.23 for easy picking.

[0081] In one possible implementation, the male elastic external hook 1.12 is used in conjunction with the female lock buckle 2.12, the blocking groove 1.11 of the male body 1.1 is inlaid with the blocking plate 2.11 of the female body 2.1, and adjacent holes form an independent space to avoid the risk of short circuit due to moisture. The full-inclusive structure design of the female body can effectively prevent water from entering the male and female bodies to play a waterproof role when the male and female are matched to form a certain angle (40-60°, preferably 60°).

The locking piece will limit the movable gap of the terminal, making the contact between the male and female ends closer and more stable; and the tapered grip 1.23 design of the male end locking piece makes it easier to take the male end locking piece;

[0083] Furthermore, one side of the double-sided non-dry cotton gasket 2.4 is adhered to the glue step 2.15 of the female end body 2.1. When the connector is in the foaming process, the wing hanging teeth 2.14 are mutually engaged with one side of the box card plate 3 to achieve the first fixation. At the same time, the other side of the double-sided non-dry cotton gasket 2.4 is tightly adhered to the other side of the box card plate 3 to achieve secondary fixation and sealing, ensuring that there is no glue leakage during foaming.
