Description

Technical Field

[0001] The utility model relates to the technical field of optical communications, in particular to a TOSA quick-clamping coupling chuck. Background Art

[0002] Because conventional TOSA coupling chucks place the power cord outside the chuck, operation requires manually inserting the power cord into the chuck from the bottom and pulling it out from the top, then inserting the TOSA device into the power socket, and finally installing the entire device into the chuck and locking it. This method involves many steps, is inconvenient, and affects production efficiency. Utility Model Content

[0003] The utility model provides a TOSA quick-clamping coupling chuck to solve the above-mentioned deficiencies in the prior art and improve the coupling and clamping efficiency of a series of products such as TOSA and BOSA.

[0004] In order to achieve the purpose of this utility model, the following technologies are proposed:

[0005] A TOSA quick-clamp coupling chuck comprises a base, a clamping member mounted on the base, a clamping drive head mounted on the base, the inner end of the clamping drive head being mounted on the clamping member, and a lower baffle plate mounted on the lower end of the base. The lower baffle plate is provided with a plug connector for inserting pins on TOSA and BOSA communication components. The clamping member can position the housing of the TOSA or BOSA communication component to ensure stability during coupling. The clamping drive head can actively drive the clamping member to move, and through the clamping member, position the housing of the TOSA or BOSA communication component.

[0006] A sinking groove is provided at the upper end of the base body, a sliding groove is provided at the bottom of the sinking groove, a positioning hole is provided at the inner end of the bottom of the sliding groove, and the clamping member is provided in the sliding groove to guide the movement of the clamping member. The positioning hole plays a role in positioning the shell of the TOSA and BOSA communication devices.

[0007] A spring is provided at the lower end of the positioning hole, and the lower end of the plug connector is passed through the spring. The spring is located above the lower baffle. The setting of the spring can move the plug connector downward when the TOSA or BOSA communication device is inserted. When the insertion is completed, the elastic force provided by the spring can be used to position the TOSA or BOSA communication device in the vertical direction.

[0008] The plug connector is cylindrical and inserted into a positioning hole. It has multiple insertion holes axially extending through it. A connector is located at the lower end of each insertion hole, which is connected to the transmission line. A retaining ring is located on the outer periphery of the plug connector, above the spring. The insertion holes facilitate the insertion of the pins of TOSA and BOSA communication devices. The retaining ring limits the vertical movement of the plug connector.

[0009] Furthermore, an arc-shaped groove is formed at the upper end of the positioning hole, and a positioning arc plate is formed on the inner circumference of the arc-shaped groove. The positioning hole, arc-shaped groove, arc-shaped positioning groove, and positioning arc plate are coaxially arranged. The positioning arc plate serves to limit the retaining ring on the plug connector. The arc-shaped positioning groove can also limit the raised ring on the housing of TOSA and BOSA communication devices.

[0010] Furthermore, a positioning arc groove is formed on the inner end of the clamping member, and an inner concave arc groove is formed on the inner periphery of the positioning arc groove, which corresponds to the arc-shaped positioning groove. The concave arc groove is clamped on the convex ring on the TOSA or BOSA communication device housing and positions the TOSA or BOSA communication device housing.

[0011] Furthermore, the outer end of the clamping member is provided with a T-slot, and the clamping drive head includes a screw threaded onto the base. The inner end of the screw is formed with a connecting post, and the inner end of the connecting post is provided with an inner post. The diameter of the connecting post is smaller than the diameter of the inner post and the diameter of the screw. The outer end of the screw is provided with a rotating head, the inner post is located in the T-slot, and the connecting post is located at the outer end of the T-slot. The provided screw can actively control the position of the clamping member, thereby facilitating the positioning of the TOSA and BOSA communication device housing through the clamping member.

[0012] Furthermore, an anti-slip pattern is provided on the outer periphery of the rotating head to facilitate the operator to rotate the rotating head.

[0013] Furthermore, a cover plate is installed at the bottom of the sink, and the clamping piece is located at the lower side of the cover plate, and the cover plate plays a guiding role for the clamping piece.

[0014] Furthermore, a protrusion is formed on the inner end of the clamping member, and the cover plate is used to limit the protrusion to facilitate subsequent positioning operations.

[0015] Furthermore, a U-shaped groove is provided on the lower baffle, and screws for fixing the lower baffle are passed through the U-shaped groove, thereby facilitating the positioning operation of the lower baffle.

[0016] Furthermore, a circular hole is provided on the lower baffle, a notch is provided on the circular hole, the positioning hole is coaxial with the circular hole, and the lower end of the plug connector is passed through the circular hole, so as to facilitate the lead-out of the connector and the transmission line.

[0017] Furthermore, the base body has a limit hole, through which a pin is inserted. The plug connector is formed with a flat surface, and the outer periphery of the pin is tangent to the flat surface. The pin acts as a limit for the plug connector, preventing it from rotating during lifting and lowering, thereby facilitating the insertion of pins on TOSA and BOSA communication devices.

[0018] The advantages of the above technical solution are:

[0019] The utility model improves the coupling and clamping efficiency of a series of products such as TOSA, BOSA, etc. BRIEF DESCRIPTION OF THE DRAWINGS
