Embodiment 3

[0072]Embodiment 3 of the sealed connector of the present invention: the difference from the above embodiments is that the sealing body in this embodiment is a split structure, including two overlapping lobes. The split petals of the sealing body are fastened on the small diameter section of the sealing contact piece after they are joined together along the direction perpendicular to the insertion. Among them, glue is coated on the joint surface of each part of the sealing body and the contact surface with the small-diameter section. When the parts are closed and the glue is solidified, the sealing body can be tightly hugged on the small-diameter section of the sealing contact, realizing The small-diameter section is in sealing fit with the sealing body, and at the same time, the outer surface of the sealing body can be tightly sealed with the cavity wall of the insulator, thereby separating the spaces at both ends of the connector. In other embodiments, when the splits are co...

Embodiment 4

[0073] Embodiment 4 of the sealed connector in the present invention: the difference from the above-mentioned embodiments is that the sealing body in this embodiment is a rigid sealing body, which cannot undergo elastic deformation itself. When facing the surface, a structure such as a sealing ring can be arranged on the inner wall of the insulator, and the sealing body can squeeze the sealing ring, thereby separating the space on the front and rear sides of the insulator; it can also be filled with sealant between the sealing body and the insulator, or over Ying fit to achieve the sealing of the two. When the part where the sealing body and the insulator are sealed and matched is the front end face or the rear end face, the insulator is provided with an inner flange corresponding to the sealing body in the front and rear direction, and the sealing body is set on the inner flange to realize the inner flange of the insulator. For the partition of the space on the front and rear...

Embodiment 5

[0074] Embodiment 5 of the sealed connector in the present invention: the difference from the above-mentioned embodiments is that in this embodiment, the part where the sealing body on the sealing contact part cooperates with the inner cavity of the insulator is the outer peripheral surface of the sealing body. When the parts are installed into the insulator, the operator uses tooling to force the sealing contact into the insulator, and the insulator and the sealing body are squeezed into the seal perpendicular to the insertion direction, so it is no longer necessary to set the sealing body along the insertion direction. Compression piece for applying force. In this embodiment, the sealing body can be made of elastically deformable material, or can be made of elastically deformable material. In other embodiments, a pressing cap can be screwed into the insulator, and the pressing cap can be moved forward or backward by the thread. The pressure cap is arranged on the side of th...

Abstract

The invention provides a sealing connector and a sealing contact piece thereof. The sealing contact piece comprises large-diameter sections at the two ends and a middle small-diameter section connected with the large-diameter sections at the two ends, and also comprises a sealing body. The sealing body is located at the middle small-diameter section of the contact piece and wraps the middle small-diameter section in a sealing mode in the direction perpendicular to the inserting direction, and the projection of the sealing body in the inserting direction at least can cover the smaller one of the maximum sizes in the two large-diameter sections in the direction perpendicular to the inserting direction; and when the sealing contact pieces are assembled in the corresponding mounting cavities,the sealing body is in sealing fit with the cavity wall of the mounting cavity. The sealing body partitions the space where the two large-diameter sections are located, so that the spaces on the two sides cannot be communicated with each other, and the sealing effect that signals are transmitted only through the contact piece in the inserting direction, and transmission of other substances can bepartitioned by the sealing body is achieved.

Description

technical field [0001] The invention relates to the technical field of connectors, in particular to a sealed connector and a sealed contact piece thereof. Background technique [0002] Existing connectors need to have waterproof and dustproof sealing capabilities when facing harsh working conditions. Therefore, not only contacts are arranged in the housing of the connector, but also a waterproof and dustproof sealing structure is arranged. The contacts are set in In the sealing structure, the sealing structure can separate the internal spaces on the front and rear sides of the casing. [0003] While the existing contacts are as figure 1 As shown in the chip contact piece 01, the plug-in end 02 of this contact piece is a clip-type structure, which can clamp the adapter contact piece, and the terminal 03 at the other end is a rolled structure, which is used for cables to be inserted and Fixed with the cable connection. This kind of contact piece is formed by punching and be...
