[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] Embodiment 1:
[0024] See also Figure 1-5 The utility model provides a technical solution: a wire-to-board waterproof connector. The application is mainly aimed at the existing connectors. The sealing ring is axially squeezed at the mating position to prevent water. The axial force at the mating position is large, and the compression of the sealing ring is easily reduced due to the external environment, resulting in the failure of the waterproof structure. The specific scheme is as follows: It includes a pin seat 1, a connecting shell 2 and a connecting wire 3. A plurality of pins are evenly arranged on the pin seat 1, wherein the pins are in a bent state, and a connecting wire sleeve 6 is connected to the lower end of the connecting wire 3. The pins are movably plugged into the corresponding connecting wire sleeve 6, and the number of pins is equal to the number of connecting wire sleeves 6. The connecting shell 2 is sleeved on the upper end of the pin seat 1, and a sealing gasket 7 is provided between the pin seat 1 and the connecting shell 2, and the sealing gasket 7 is arranged below the waterproof part 5. Among them, the sealing gasket 7 is glued to the upper end of the pin seat 1, and the setting of the sealing gasket 7 can increase the contact sealing between the pin seat 1 and the connecting shell 2.
[0025] like Figure 2 and Figure 3 On the upper end of the connection housing 2, a clamping limit plate 4 is clamped, and the clamping fulcrums of the clamping limit plate 4 and the connection housing 2 are distributed in a square shape on the outside of the connection housing 2. The fulcrums for connecting the clamping limit plate 4 and the connection housing 2 in a square shape can further improve the connection stability of the connection housing 2 and the clamping limit plate 4.
[0026] Furthermore, a waterproof member 5 is provided between the clamping limit plate 4 and the connecting shell 2. Insertion holes 51 for inserting the connecting wire 3 are provided at intervals on the waterproof member 5. Hollow protrusions 53 are provided at intervals on the outside of the waterproof member 5. A V-shaped connector 52 is provided between adjacent hollow protrusions 53. The longitudinal section of the V-shaped connector 52 is a left-right symmetrical "V" shape, and the V-shaped connector 52 is provided on the outside of the waterproof member 5. The V-shaped angle of the V-shaped connector 52 faces the waterproof member 5. The V-shaped connector 52 and the hollow protrusion 53 are glued. Among them, the V-shaped connector 52 and the hollow protrusion 53 are made of flexible rubber. In the initial state, the angle of the V-shaped connector 52 is at the maximum. After installation, the waterproof member 5 is squeezed, so that the V-shaped angle of the V-shaped connector 52 is reduced, and then the top of the V-shaped connector 52 fits the clamping limit plate 4, which further improves the waterproof effect of the connector.
[0027] See also Figure 2 and Figure 3 , elastic clips 61 for clamping the connecting wire sleeve 6 and the connecting shell 2 are symmetrically arranged on the outer side of the connecting wire sleeve 6. Inward bosses 62 are arranged at intervals from top to bottom on the inner side of the connecting wire sleeve 6, and the bosses 62 are in contact with the pins. The elastic clips 61 and the connecting wire sleeve 6 are processed as one piece, and the elastic clips 61 and the connecting wire sleeve 6 are made of hard plastic. When the connecting wire sleeve 6 and the pin socket 1 are connected, the angle between adjacent elastic clips 61 can be reduced during the process of inserting the connecting wire sleeve 6 into the pin socket 1, thereby facilitating plug-in. After the elastic clips 61 are placed under the connecting shell 2, the elastic clips 61 return to their initial state, thereby preventing the retraction of the connecting wire 3, and further ensuring the connection stability of the connector.
[0028] Embodiment 2:
[0029] See also Figure 6 , wherein the pins on the pin socket 1 are in a vertical state. Setting the pins in a vertical state can meet different connection needs. It is worth noting that the pin sockets 1 of the first embodiment and the second embodiment have the same dimensions except for the pin shapes; this makes it easy to replace the pin socket 1 to meet connection needs.
[0030] The other structures are the same as those in the first embodiment.
[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
