In the related art, a housing of the optical fiber adapter has a hollow structure, and a connection structure for detachably connecting the two opposite ends of the optical fiber adapter with the optical fiber connector is provided. The connecting structure comprises a clamping arm arranged in a shell and a groove arranged on the shell of the optical fiber connector, when the optical fiber connector is inserted into the shell of the optical fiber adapter, the groove is positioned in the shell and is clamped with the free end of the clamping arm so as to fix the optical fiber connector and the optical fiber adapter. When it is desired to separate the fiber optic connector from the fiber optic adapter, the rod-like prongs of the removal tool are guided through the notches in the housing of the fiber optic connector to the grooves and the catch arms, and then the rod-like prongs slide under the catch arms to raise the catch arms and move the catch arms away from the grooves, thereby separating the fiber optic connector from the fiber optic adapter. However, since the clip arm is located in the housing and the space near the clip arm is narrow, the rod-shaped tip is difficult to insert under the clip arm, and the clip arm rubs against the housing, which increases the resistance of the optical fiber connector to be separated from the housing, the difficulty of separating the optical fiber adapter and the optical fiber connector in the related art is high.

In view of the above, the inventors of the present disclosure have provided a connection assembly including a detachably connected adapter and a connector, a disconnection tool for disconnecting the adapter and the connector, and a cable having the connector. Wherein, the shell of the connector of the present disclosure includes a cylindrical portion, and a first fastening portion and a second fastening portion that are extended on an outer surface of a cylinder wall of the cylindrical portion. The adapter comprises a first tubular part and two first clamping parts capable of elastic deformation, wherein a first notch is formed in each of the two opposite ends of the first tubular part, a first clamping part is arranged in each first notch, and the first ends of the first clamping parts are fixedly connected with the first tubular parts. The separating tool comprises a main body part, an inserting part and a clamping part, wherein the first end of the inserting part and the first end of the clamping part are both in fastening connection with the first end of the main body part.

When the connector and the adapter are in butt joint, the part of the cylindrical part is positioned in the first tubular part, and the first clamping part is clamped with the first fastening part so as to fix the adapter and the connector.

When the connector and the adapter are separated, the separation tool moves in the axial direction of the first tubular portion so that the insertion portion is inserted into the first tubular portion, and the insertion portion is located between the first clamping portion and the cylindrical portion so that the second end of the first clamping portion moves in a direction away from the cylindrical portion, in other words, the first clamping portion is elastically deformed so that the first clamping portion is no longer clamped with the first fastening portion, so that the connector and the adapter can be separated. In addition, in the process that the first clamping part is elastically deformed by the insertion part, the clamping part is clamped with the second fastening part, so that the connector is fixed with the separating tool, and the main body part is pulled to move along the direction away from the adapter, so that the connector is separated from the adapter.

Because the first clamping portion is located in the first notch, the space of elastic deformation (along the direction deviating from the cylindrical portion) of the first clamping portion is almost infinite, so that the insertion portion is ensured to thoroughly separate the first clamping portion from the first fastening portion. In addition, the insertion part is positioned outside the cylindrical part, so that the use difficulty of the separating tool is low. Besides, as the clamping part is clamped with the second fastening part, the separating tool can drive the connector to be away from the adapter, and in the process of being away from, the first clamping part is always separated from the first fastening part, so that the setting can be reduced, the connector is pulled to be separated from the adapter through the separating tool, the separation difficulty of the connector and the adapter can be reduced, and in addition, the connector, the adapter and a cable with the connector can be prevented from being damaged.

The cable of the present disclosure may be a cable such as an electric cable or an optical cable for transmitting signals or electric power, etc. The connection assembly of the present disclosure may be used for cables such as electric cables or optical cables, and the present disclosure is described in detail with respect to the application of the connection assembly to optical cables, but does not constitute a limitation on the application of the connection assembly.

The connector, adapter, connection assembly, separation tool and cable provided by the present invention will be described in detail with reference to specific embodiments.

Fig. 1 is an exploded view of a connection assembly of the present embodiment, fig. 2 is a first perspective view of a housing of the present embodiment, fig. 3 is a second perspective view of the housing of the present embodiment, fig. 4 is a front view of the housing of the present embodiment, and fig. 5 is a left side view of the housing of the present embodiment.

Referring to fig. 1, the present embodiment provides a connection assembly 300 and a separation tool 400, the connection assembly 300 including an adapter 200 and a connector 100, opposite ends of the adapter 200 being used to connect with one connector 100 to connect a cable 500 connected with both connectors 100. Wherein the connector 100 is mounted at an end of the cable 500 so that the cables 500 at both ends of the adapter 200 can be connected to achieve a communication connection. In addition, the separation tool 400 can be mated with the adapter 200 and the connector 100 of the present embodiment, respectively, to separate the adapter 200 and the connector 100, in other words, the connection assembly 300 has a combined state and a separated state, and the separation tool 400 allows the connection assembly 300 to be switched between the combined state and the separated state.

Referring to fig. 2 and 3, the connector 100 provided in the present embodiment includes at least a housing 110, and the housing 110 may include a cylindrical portion 111, a first fastening portion 112, and a second fastening portion 113. Wherein, after the adapter 200 is mated with the connector 100, a portion of the cylindrical portion 111 is positioned within the adapter 200, for example, in the present embodiment, the closed end of the cylindrical portion 111 is positioned inside the adapter 200, and the open end of the cylindrical portion 111 is positioned outside the adapter 200.

Wherein, the first fastening portion 112 and the second fastening portion 113 are both disposed on the outer surface of the cylindrical wall of the cylindrical portion 111 and are both fastened to the cylindrical portion 111, the first fastening portion 112 is used for being detachably connected with the first clamping portion 220 of the adapter 200, and the second fastening portion 113 is used for being clamped with the clamping portion 430 of the separating tool 400.

It can be appreciated that when the portion of the cylindrical portion 111 is located in the first tubular portion 210 of the adapter 200, the first clamping portion 220 is clamped with the first fastening portion 112, so that the connector 100 is fastened with the adapter 200, and thus the connector 100 and the adapter 200 form the connection assembly 300, and two cables 500 or one cable 500 and a device to be connected can be connected. In addition, the second fastening portion 113 is located outside the first tubular portion 210 in order to be able to be engaged with the engagement portion 430, so that the connector 100 and the adapter 200 are separated by the separation tool 400.

The longitudinal section of the cylindrical portion 111 may be circular or polygonal, wherein the longitudinal section of the cylindrical portion 111 is perpendicular to the axial direction of the cylindrical portion 111, for example, in the present embodiment, the longitudinal section of the cylindrical portion 111 is a rectangular annular structure, and the first fastening portion 112 and the second fastening portion 113 are located on different sides of the cylindrical portion 111, respectively.

The first fastening portion 112 and the second fastening portion 113 are both disposed on the outer surface of the cylindrical wall of the cylindrical portion 111, so that the connection difficulty of the first clamping portion 220 and the first fastening portion 112, and the connection difficulty of the clamping portion 430 and the second fastening portion 113 can be reduced, and in addition, the separation difficulty of the connector 100 and the adapter 200 can be reduced.

The first fastening portion 112 and the second fastening portion 113 are each a protrusion provided on the wall of the cylindrical portion 111, and the protrusion may be a block structure, a plate structure, a column structure, or the like, and is not particularly limited in this embodiment, and in addition, the shapes of the first fastening portion 112 and the second fastening portion 113 may be different or the same.

For example, in some examples, the first fastening portion 112 is a long strip-shaped plate-like structure, and in particular, a cross section of the first fastening portion 112 includes a rectangular section and a semicircular section, a straight edge of the semicircular section is connected to one side of the rectangular section, and a length of the straight edge is equal to a side length of a side of the rectangular section connected to the straight edge. In addition, the longitudinal direction of the first fastening portion 112 is parallel to the axial direction of the cylindrical portion 111, which helps to reduce the difficulty of the engagement of the first engaging portion 220 and the first fastening portion 112.

In some possible implementations, the cylindrical portion 111, the first fastening portion 112, and the second fastening portion 113 may be integrally formed, so that on one hand, the manufacturing efficiency of the housing 110 may be improved, for example, the housing 110 may be manufactured by injection molding, and on the other hand, the connection strength between the cylindrical portion 111 and the first fastening portion 112 and the second fastening portion 113 may be improved, so as to improve the service life of the housing 110.

In some possible implementations, along the axial direction of the cylindrical portion 111, the end face of the open end of the cylindrical portion 111 is flush with the end face of the second fastening portion 113 that abuts against the open end of the cylindrical portion 111, so that, on the one hand, the size of the housing 110 along the axial direction of the cylindrical portion 111 can be reduced, which contributes to reducing the volume of the connector 100, and, on the other hand, the manufacturing difficulty of the housing 110 can be reduced.

In some possible implementations, referring to fig. 2 and 3, the second fastening portion 113 includes at least one first plate portion 1131, a first end of the at least one first plate portion 1131 is fastened to the cylinder wall of the cylindrical portion 111, and a second end of the at least one first plate portion 1131 is configured to be clamped to the clamping portion 430, so that the connector 100 and the separation tool 400 are fastened to each other, and the separation tool 400 may move the connector 100 in a direction away from the adapter 200.
