[0021] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0022] See also Figure 1-Figure 3 , Figure 1 It is a three-dimensional structural schematic diagram of the optical fiber splicing box provided by the embodiment of the utility model; Figure 2 It is a schematic diagram of a first partial explosion structure of the optical fiber splicing box provided by an embodiment of the utility model; Figure 3 1 is a schematic diagram of a second partial explosion structure of an optical fiber splicing box provided by an embodiment of the utility model. The optical fiber splicing box 1 of the utility model comprises a first box body 11, a second box body 12 and a connector 13. The first box body 11 is provided with first wire grooves 111 on both sides, and the second box body 12 is provided with second wire grooves 121 on both sides. When the first box body 11 and the second box body 12 are covered, the first wire grooves 111 and the second wire grooves 121 together enclose a circular hole for the optical cable to pass through.

[0023] The second box body 12 is provided with protruding connection seats 14 on both sides, and the connection seats 14 are provided with wire grooves concentric with the second wire grooves 121, and the curvature of the wire grooves is smaller than that of the second wire grooves 121. The connecting piece 13 is provided with a groove, and when the first box body 11 and the second box body 12 are covered, the groove and the wire groove are respectively in contact with the upper and lower sides of the optical cable.

[0024] When splicing the optical cable, first wind the optical cable into a roll, and put the rolled optical cable into the optical fiber splicing box 1, so that the joint part of the optical cable passes through the round hole, and then connect the connector 13 with the connecting seat 14, and make the groove on the connector 13 fit with the optical cable, and at the same time make the wire groove on the connecting seat 14 fit with the optical cable, so as to form a clamping effect on the optical cable joint part to prevent the optical cable joint part from shaking and causing the optical cable in the optical fiber splicing box 1 to become unwound.

[0025] Since the curvature of the wire groove is smaller than that of the second wire groove 121, when the wire diameter of the optical cable matches the diameter of the round hole, the joint part of the optical cable can be fixed under the clamping of the round hole. When the wire diameter of the optical cable is smaller than the diameter of the round hole, the clamping force of the groove and the wire groove on the optical cable can be adjusted by adjusting the distance between the connector 13 and the connecting seat 14, thereby achieving the fixation of the optical cable with smaller wire diameter specifications, thereby improving the flexibility of use of the optical fiber splicing box 1.

[0026] In one embodiment, the curvature of the first wire groove 111 and the second wire groove 121 are both 180°, so that after the first box body 11 and the second box body 12 are covered, the first wire groove 111 and the second wire groove 121 are together enclosed to form a circular hole, so that the optical cable connector part can pass through the circular hole. The curvature of the wire groove is 130°, so that the optical cable connector part can be installed in the wire groove after passing through the circular hole, and the connector 13 can be used to adjust the spacing relative to the connecting seat 14, thereby achieving a clamping effect on the optical cable connector part to prevent the optical cable connector part from shaking.

[0027] In an embodiment of the utility model, the curvature of the groove is equal to the curvature of the wire groove, so as to increase the adjustment range of the distance between the connector 13 and the connector seat 14, so that the optical fiber splicing box 1 can adapt to optical cables with smaller diameters and clamp and fix the optical cable connector.

[0028] In an embodiment of the utility model, a protruding slider 132 is provided on the connecting member 13, and a sliding groove 112 for the sliding slider 132 to slide is opened on the side of the first box body 11. When the optical cable is connected, the connecting member 13 is moved and the connecting member 13 slides in the sliding groove 112 through the slider 132, so as to adjust the distance between the connecting member 13 and the connecting seat 14, and prevent the connecting member 13 from deflecting when connected to the connecting seat 14, thereby affecting the clamping effect of the optical cable joint part.

[0029] In an embodiment of the utility model, an elastic member 15 is provided in the slide groove 112, and the two ends of the elastic member 15 are respectively pressed against the surfaces of the slider 132 and the slide groove 112 to squeeze the connector 13 and the connector seat 14 to fit together, so that when the first box body 11 and the second box body 12 are covered, the connector 13 and the connector seat 14 are preferentially pressed against the surface of the optical cable joint part under the elastic force of the elastic member 15, so as to achieve the pre-fixing effect of the optical cable joint part, and then after the first box body 11 and the second box body 12 are fixed, the final fixation of the optical cable joint part can be achieved by fixing the position of the connector 13, so as to prevent the occurrence of unwinding during the optical cable connection operation. In the above embodiment, the elastic member 15 is a spring, and the two ends of the spring are respectively pressed against the surfaces of the slider 132 and the slide groove 112, so as to squeeze the slider to move in the direction of the connector seat 14 and make the connector 13 close to the connector seat 14.

[0030] In an embodiment of the utility model, the connector 13 is connected to the connecting seat 14 by bolts. The connector 13 is provided with a through hole 133 for the bolt to pass through. The connecting seat 14 is provided with a threaded hole 142 for the bolt to be threadedly connected at a position corresponding to the through hole 133. When the connector 13 and the connecting seat 14 are connected, the bolt passes through the through hole 133 and is connected to the threaded hole 142, thereby fixing the position of the connector 13 and preventing the optical cable joint from shaking and unwinding.

[0031] In an embodiment of the utility model, a first wire clamping groove concentric with the wire passing groove is further provided on the connecting seat 14, and the curvature of the first wire clamping groove is smaller than that of the wire passing groove, so as to limit the optical cable joint part under the action of the first wire clamping groove, and further prevent the optical cable joint part from shaking and causing the optical cable in the optical fiber connection box 1 to become unwound.

[0032] In an embodiment of the utility model, a second wire clamping groove aligned with the first wire clamping groove is provided on the connecting member 13, and the curvature of the second wire clamping groove is greater than that of the first wire clamping groove, so that after the connecting member 13 and the connecting seat 14 are fixed, the second wire clamping groove covers the first wire clamping groove and forms a clamping effect on the optical cable connector part, thereby further preventing the optical cable connector part from shaking.

[0033] In an embodiment of the utility model, the first anti-slip groove 16 is provided in the wire groove and the groove to strengthen the friction force on the optical cable joint part under the contact action of the first anti-slip groove 16 and the optical cable joint part, thereby preventing the optical cable joint part from rotating or sliding and causing unwinding. The first wire clamping groove and the second wire clamping groove are both provided with second anti-slip groove 17 to strengthen the friction force on the optical cable joint part under the contact action of the second anti-slip groove 17 and the optical cable joint part, thereby preventing the optical cable joint part from rotating or sliding and causing unwinding.

[0034] In an embodiment of the present invention, the first anti-slip grooves 16 are vertical anti-slip grooves, and the second anti-slip grooves 17 are horizontal anti-slip grooves, so as to increase the friction force of the connector 13 and the connector seat 14 on the optical cable joint part when the first anti-slip grooves 16 are used to prevent the optical cable joint part from rotating, and increase the friction force of the connector 13 and the connector seat 14 on the optical cable joint part when the second anti-slip grooves 17 are used to prevent the optical cable joint part from being pulled out of the optical fiber splicing box 1 when it is subjected to tension. In other embodiments of the present invention, the first anti-slip grooves 16 are horizontal anti-slip grooves, and the second anti-slip grooves 17 are vertical anti-slip grooves.

Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.
