Description

Technical Field

[0001] The utility model relates to the field of optical connectors, in particular to a connector structure and an optical connector with good sealing performance. Background Art

[0002] The optical connector uses two insulators to clamp the contact or uses a gear sleeve to fix the contact. It is not convenient for users to make wires on site when the two insulators clamp the contact, and the gear sleeve fixation cannot achieve axial sealing between the contact 2 and the insulator 7. The structure of the contact fixed by the gear sleeve 8 is as follows: Figure 5 In order to achieve axial sealing, the general connector and the contact piece usually use an insulator as an intermediate medium to achieve insulator fixation.

[0003] However, when this structure is used, the position accuracy of the holes between the contacts of the same position after the plug and the socket are inserted into each other will have large deviations due to the accumulated tolerance. In particular, for multi-core optical connectors, the alignment of the mating contacts when the plug and the socket are inserted into each other will have a great impact on the attenuation and other performance indicators of the product. In order to ensure the position accuracy of the holes between the multi-core contacts, it is necessary to improve the manufacturing accuracy of the parts, which will increase the processing cost of the parts.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

Figure 1 As shown, the connector structure includes a housing 1 and an optical contact, wherein the housing is provided with a hole structure for fixing the optical contact; and the housing is integrally formed with an insulator around the hole structure.

[0026] Through the above structural optimization, the hole structure is directly processed on the shell to install the optical contact, which ensures the hole spacing, and can ensure the position accuracy of the contacts of the same position after the socket and the plug are plugged in, thereby improving the performance of the multi-core optical connector.

[0027] The hole structure is used to fix the optical contact. It is a straight through hole. The inner diameter of the hole structure can be matched with the maximum diameter of the optical contact. The insulator and the shell are integrally formed and wrapped around the optical contact. That is, the shell and the insulator are designed as an integrated structure, which reduces the positioning error of the insulator when it is installed in the shell, and further improves the position accuracy of the contacts of the same position after the plug is inserted. It should be noted here that since the shell and the insulator are integrated, the attachment of this solution Figure 1 , 4 There is no partition between the shell and the insulator.

A groove structure is provided on the hole structure, and a collar is provided in the groove structure. The collar protrudes from the groove structure to limit the optical contact. Figure 1 The use of a clamping ring can realize the axial limit of the optical contact, facilitate the on-site operation of the user, and ensure the axial seal between the contact and the housing.

[0030] With the above connector structure, the optical contact can be one, two or more. Especially in a multi-core optical connector, the above structure can significantly improve the position accuracy of the contacts of the same position after the plugs are plugged in.

[0031] The second aspect of the utility model provides an optical connector, such as Figure 4 As shown, it includes a socket 61 and a plug 62 adapted to the socket 61, and the socket 61 and the plug 62 are both a connector structure described in the first aspect and any possible design thereof.

[0032] In an optical connector, the optical contact structures of the socket 61 and the plug 62 are respectively as follows: Figure 2 , 3 shown.
