Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber communication, in particular to a push-pull type connector unlocking structure. Background Art

[0002] At present, connectors with a locking structure are generally used in the market to connect with cables to improve the connection stability. However, under space limitations, the existing connectors with a locking structure generally have the phenomenon of inconvenient plugging and unplugging operations in a high-density wiring environment. Summary of the Invention

[0003] Aiming at the above problems of the existing connectors, the present invention aims to provide a push-pull type connector unlocking structure with convenient plugging and unplugging operations and high stability.

[0004] The specific technical solutions are as follows:

[0005] A push-pull type connector unlocking structure includes a main body seat for connecting the connector, a wire sleeve assembly slidably disposed on the main body seat and sleeved outside the cable connected to the connector, and a locking assembly for locking the wire sleeve assembly to the main body seat. When the wire sleeve assembly is pulled outwards, the locking assembly releases the locking of the wire sleeve assembly, so that the wire sleeve assembly slides outwards relative to the main body seat, and the wire sleeve assembly is rotatably disposed relative to the main body seat.

[0006] As a further improvement and optimization of this solution, the side wall of the end of the wire sleeve assembly away from the connector is provided with an opening.

[0007] As a further improvement and optimization of this solution, the part of the side wall of the wire sleeve assembly with an opening is flattened.

[0008] As a further improvement and optimization of this solution, the wire sleeve assembly includes:

[0009] A push rod, which is sleeved outside the cable, and one end side wall of the push rod is provided with an opening;

[0010] An unlocking sleeve, which is slidably disposed on the main body seat, and the other end of the push rod is rotatably disposed in the unlocking sleeve. The locking assembly is used to lock the unlocking sleeve. When the unlocking sleeve is pulled outwards through the push rod, the locking assembly releases the locking of the unlocking sleeve, so that the wire sleeve assembly slides outwards relative to the main body seat.

[0011] As a further improvement and optimization of this solution, a limiting assembly is further provided between the push rod and the main body seat. When the locking assembly locks the unlocking sleeve, the limiting assembly circumferentially limits the push rod.

[0012] As a further improvement and optimization of this solution, the limiting component includes: a plurality of limiting grooves circumferentially distributed at the other end of the push rod and at least one limiting block provided on the main body seat. When the wire sleeve component is pushed inward and the locking component locks the unlocking sleeve, the limiting block slides into one of the limiting grooves and forms a circumferential limiting fit with the limiting groove.

[0013] As a further improvement and optimization of this solution, a plurality of limiting strips are circumferentially provided at one end of the push rod. The limiting grooves are formed between adjacent two of the limiting grooves, and a hook is provided at the end of each of the limiting strips. Each hook is in limiting fit with one end of the unlocking sleeve close to the main body seat.

[0014] As a further improvement and optimization of this solution, each of the limiting strips is an elastic plastic part. When one end of the push rod is sleeved in the unlocking sleeve, the plurality of limiting strips radially converge inward.

[0015] As a further improvement and optimization of this solution, the locking component includes: an unlocking pressure plate, the unlocking pressure plate is hinged on the main body seat, and at least one clamping block is provided at the bottom of one end of the unlocking pressure plate. At least one clamping groove is provided on the unlocking sleeve. The bottom of the other end of the unlocking pressure plate abuts against a latch arm which is inclinedly arranged on the connector and can be elastically deformed. The clamping block is clamped into the clamping groove by the elastic force of the latch arm.

[0016] As a further improvement and optimization of this solution, one side surface of the clamping block has an inclined surface, and the top of one side wall of the clamping groove has a guiding arc surface, and the guiding arc surface is in contact with the inclined surface.

[0017] The positive effects of the above technical solutions compared with the prior art are as follows:

[0018] 1. In the present utility model, the wire sleeve component can be rotatably arranged relative to the main body seat, meeting the wire routing directions of cables at different angles, not only reducing the installation space requirement for the connector, but also making the cable routing tidy and facilitating the plugging and unplugging operations of the connector.

[0019] 2. In the present utility model, the side wall of the end of the wire sleeve component away from the connector is provided with an opening. When manually applying an external pulling or internal pushing force to one end of the cable component, the wire routing direction (bending direction) of the cable faces the opening of the wire sleeve component, and the bending length of the cable is not occupied during the plugging and unplugging operations, avoiding the operation limitation due to the cable routing bending in a narrow space, and further facilitating the plugging and unplugging operations of the connector.

[0020] 3. In the present utility model, the part of the side wall of the wire sleeve component with an opening is flattened, facilitating the pinching of the wire sleeve component by fingers in a narrow space, and further facilitating the plugging and unplugging operations of the connector.

[0021] 4. In the present utility model, the unlocking sleeve and the push rod are separately arranged, and the push rod is rotatably arranged relative to the unlocking sleeve. The independent design of the unlocking sleeve improves the operation reliability.

[0022] 5. In the present utility model, in order to stabilize the cable to a predetermined routing direction and improve the connection stability of the cable, a limiting component is further provided between the push rod and the main body seat. When the locking component locks the unlocking sleeve, the limiting component circumferentially limits the push rod. Description of the Drawings

Figure 2 It is an exploded view of an unlocking structure of a push-pull connector of the present utility model. Figure 3 It is a partial structural view of an unlocking structure of a push-pull connector of the present utility model. Figure 4 It is a schematic structural view of a wire sleeve assembly of an unlocking structure of a push-pull connector of the present utility model. Figure 5 It is a partial structural view of an unlocking structure of a push-pull connector of the present utility model. As Figures 1-5 shown, it shows an unlocking structure of a push-pull connector 1 of a preferred embodiment, including a main body seat 3 for connecting the connector 1, a wire sleeve assembly 5 slidably arranged on the main body seat 3 and sleeved outside the cable 2 connected to the connector 1, and a locking assembly for locking the wire sleeve assembly 5 to the main body. When the wire sleeve assembly 5 is pulled outward, the locking assembly releases the locking of the wire sleeve assembly 5, so that the wire sleeve assembly 5 slides outward relative to the main body seat 3, and the wire sleeve assembly 5 is rotatably arranged relative to the main body seat 3.

[0033] In this embodiment, the wire sleeve assembly 5 is rotatably arranged relative to the main body seat 3, which meets the routing directions of the cable 2 at different angles, not only reduces the installation space requirements for the connector 1, but also makes the cable 2 routing neat and facilitates the plugging and unplugging operations of the connector 1.

[0034] Furthermore, as a preferred embodiment, the side wall of the end of the wire sleeve assembly 5 away from the connector 1 is provided with an opening. When manually applying an external pulling or internal pushing force to one end of the cable 2 assembly, the routing direction (bending direction) of the cable 2 faces the opening of the wire sleeve assembly 5. During the plugging and unplugging operation, it does not occupy the bending length of the cable 2, avoiding operation restrictions due to routing bending in a narrow space, and further facilitating the plugging and unplugging operation of the connector 1.

[0035] Furthermore, as a preferred embodiment, the part of the side wall of the wire sleeve assembly 5 with an opening is flattened, which is convenient for pinching the wire sleeve assembly 5 with fingers in a narrow space, and further facilitates the plugging and unplugging operation of the connector 1.

[0036] Furthermore, as a preferred embodiment, the wire sleeve assembly 5 includes a push-pull rod 51 and an unlocking sleeve 52. The push-pull rod 51 is sleeved outside the cable 2. One end side wall of the push-pull rod 51 is provided with an opening. The unlocking sleeve 52 is slidably arranged on the main body seat 3. The other end of the push-pull rod 51 is rotatably arranged in the unlocking sleeve 52. A locking component is used to lock the unlocking sleeve 52. When the unlocking sleeve 52 is pulled outwards by the push-pull rod 51, the locking component releases the lock on the unlocking sleeve 52, so that the wire sleeve assembly 5 slides outwards relative to the main body seat 3.

[0037] In this embodiment, the unlocking sleeve 52 and the push-pull rod 51 are separately arranged. The push-pull rod 51 can be rotatably arranged relative to the unlocking sleeve 52. The independent design of the unlocking sleeve 52 improves the operation reliability.

[0038] In another embodiment, one end of the push-pull rod 51 has anti-slip ribs 514.

[0039] Furthermore, as a preferred embodiment, in order to stabilize the cable 2 to a predetermined routing direction and improve the connection stability of the cable 2, a limiting component is also provided between the push-pull rod 51 and the main body seat 3. When the locking component locks the unlocking sleeve 52, the limiting component circumferentially limits the push-pull rod 51.

[0040] Furthermore, as a preferred embodiment, the limiting component includes a plurality of limiting grooves 513 arranged circumferentially at the other end of the push-pull rod 51 and at least one limiting block 31 arranged on the main body seat 3. When the wire sleeve assembly 5 is pushed inwards and the locking component locks the unlocking sleeve 52, the limiting block 31 slides into one of the limiting grooves 513 and forms a circumferential limiting fit with the limiting groove 513.

[0041] Furthermore, as a preferred embodiment, the one end of the push-pull rod has a plurality of limiting strips 511 circumferentially. A limiting groove 513 is formed between adjacent two limiting grooves 513, and each end of each limiting strip 511 has a hook 512. Each hook 512 is in limiting fit with one end of the unlocking sleeve 52 close to the main body seat 3.

[0042] Further, as a preferred embodiment, each limiting strip 511 is an elastic plastic part. When one end of the push-pull rod is sleeved in the unlocking sleeve 52, several limiting strips 511 radially contract inward.

[0043] Further, as a preferred embodiment, the locking assembly includes: an unlocking pressing plate 4, which is hinged on the main body base 3, and at least one clamping block 41 is provided at the bottom of one end of the unlocking pressing plate 4. At least one clamping groove 521 is provided on the unlocking sleeve 52. The bottom of the other end of the unlocking pressing plate 4 abuts against a latch arm 11 which is inclinedly arranged on the connector 1 and can be elastically deformed. The elastic force of the latch arm 11 enables the clamping block to be clamped into the clamping groove 521.

[0044] In one embodiment, both the latch arm 11 and each limiting strip 511 can be polyurethane elastomers.

[0045] Further, as a preferred embodiment, in order to enable the clamping block 41 to smoothly disengage from the clamping groove 521 for unlocking when the wire sleeve assembly 5 is pulled and stressed, one side surface of the clamping block 41 has an inclined surface 42, and the top of one side wall of the clamping groove 521 has a guiding arc surface 522. The guiding arc surface 522 contacts the inclined surface 42. More preferably, there are two clamping blocks 41, which are respectively located on both sides of the unlocking pressing plate 4, and two corresponding clamping grooves 521 are provided.

[0046] The above are only preferred embodiments of the present invention, and do not limit the implementation manners and protection scope of the present invention. For those skilled in the art, it should be realized that all equivalent replacements and obvious changes made by using the description and illustrations of the present invention should be included in the protection scope of the present invention.
