The loop back module is the key of network switch design and verification test. They replace pluggable transceivers and other interconnect devices for early design verification stages, manufacturing testing, and to assist in field deployment. The loop module needs to be plugged and pulled out for a plurality of times in the service life, so the stability and the reliability of the fixing mechanism of the loop module are highly required

At present, the fixing mechanism of the loop module is poor in structural reliability and stability, so that the loop assembly is easy to damage in the use of plugging and unplugging, and the loop assembly and the port assembly are not reliably connected.

According to the elastic piece, the limiting surface which is intersected with the plug-in port and has the included angle smaller than 90 degrees is arranged on the loop body, so that when the limiting surface abuts against the elastic piece, the limiting surface and the elastic piece can have interaction forces in multiple directions, and the relative position relationship between the limiting surface and the elastic piece is stable when the limiting surface abuts against the elastic piece. In the process of separating the loop assembly from the limiting surface, the limiting surface can guide the elastic piece to slide along the limiting surface, so that the limiting surface of the loop main body can be separated from the elastic piece relatively smoothly, and the elastic piece is prevented from being clamped in the mounting cavity due to mutual interference between the elastic piece and the limiting surface.

The loop back assembly and the communication device provided by the application are described in detail below in connection with specific embodiments.

The embodiment of the application provides a communication device, which comprises a loop back component and a port component, wherein the loop back component can be connected with the port component, so that the loop back component and the port component can be in communication connection. The loop component is detachably connected with the port component, so that the loop component can be plugged and pulled by the port component for a plurality of times, and of course, the loop component can be plugged and pulled by other port components, and the port component can be a switch. In the conventional loop assembly and port assembly multiple plug cooperation, because the loop assembly and port assembly matched fixing mechanism needs to be independently operated by a user, and the fixing mechanism is poor in structural reliability, the loop assembly is poor in plugging reliability with the port assembly after long-term use, and the loop assembly is easy to damage.

Based on this, the embodiment of the application further provides a loop back assembly, which can be applied to the above communication device, so that the loop back assembly and the port assembly have reliable and stable connection effect.

Referring to fig. 1, the loop assembly of the present application includes a base 100, an elastic member 200, and a loop body 300, wherein the loop body 300 is a base member of the loop assembly, and the loop body 300 can be in plug-in fit with a port assembly. The base 100 may be a frame structure with a cavity inside, so the base 100 has a mounting cavity 110 therein, the surface of the base 100 is provided with an inserting port 120, the inserting port 120 is communicated with the mounting cavity 110, and the loop body 300 may be inserted into the mounting cavity 110 through the inserting port 120 of the base 100 or removed from the mounting cavity 110 through the inserting port 120. When the loop back assembly is applied to a communication device, an interface of the communication device can be arranged in the mounting cavity 110 of the base 100, and when the loop back body 300 is inserted into the mounting cavity 110 through the insertion interface 120, a communication connection end of the loop back body 300 can be in butt joint with an interface of the port assembly. Of course, the interface of the port assembly may also be disposed outside the mounting cavity 110 of the base 100, and the specific mounting position of the port assembly is not limited in this application.

Referring to fig. 2 to 4, the elastic member 200 is disposed in the mounting cavity 110 of the base 100, and the elastic member 200 may be fixed on an inner wall of the mounting cavity 110, and the outer wall of the loop body 300 is provided with a limiting surface 311, when the loop body 300 is installed into the mounting cavity 110 from the plug interface 120 of the base 100, the limiting surface 311 of the outer wall of the loop body 300 may be opposite to the inner wall of the mounting cavity 110, so that the limiting surface 311 may be in contact fit with the elastic member 200. When the loop body 300 is located in the mounting cavity 110 of the base 100, the limiting surface 311 of the loop body 300 intersects with the direction of the plug 120, and the included angle between the limiting surface 311 and the direction of the plug 120 is smaller than 90 degrees, it should be understood that when the mounting cavity 110 of the base 100 is in a straight-line channel structure, the extending direction of the limiting surface 311 and the mounting cavity 110 also intersect and the included angle is smaller than 90 degrees, that is, the limiting surface 311 of the loop body 300 is an inclined surface.

When the loop body 300 is located in the mounting cavity 110 of the base 100, the limiting surface 311 of the loop body 300 faces the socket 120 of the base 100, so that the direction from the limiting surface 311 to the socket 120 is the direction from the inside of the mounting cavity 110 to the outside of the mounting cavity 110, and the direction from the socket 120 to the limiting surface 311 is the direction from the socket 120 to the inside of the mounting cavity 110, in which the loop body 300 is inserted. The loop body 300 has a first state and a second state, between which the loop body 300 is switchable.

When the loop body 300 is in the first state, the limiting surface 311 of the loop body 300 abuts against the elastic member 200, and the limiting surface 311 of the loop body 300 faces the socket 120, so that after the elastic member 200 abuts against the limiting surface 311, the abutting force of the elastic member 200 against the limiting surface 311 faces the limiting surface 311, i.e. faces away from the socket 120. When the loop body 300 needs to be pulled out of the mounting cavity 110 from the mounting cavity 110 through the plug-in port, a user needs to apply a pulling force from the limiting surface 311 to the plug-in port 120 to the loop body 300, and at this time, the pulling force is opposite to the supporting force of the elastic member 200 against the limiting surface 311, and when the pulling force is greater than the supporting force, the loop body 300 can move from the mounting cavity 110 to the mounting cavity 110. Therefore, when the pulling force applied to the loop body 300 is smaller than the supporting force of the elastic member 200 against the limiting surface 311, the supporting force of the elastic member 200 against the limiting surface 311 can limit the loop body 300 in the mounting cavity 110, so that the loop body 300 can be kept stable in the mounting cavity 110, and the loop body 300 can be connected with the port assembly stably and reliably.

When the loop body 300 is in the second state, the limiting surface 311 of the loop body 300 is separated from the elastic member 200, and the loop body 300 may be located in the mounting cavity 110 of the base 100 or located outside the mounting cavity 110, which is not limited in this application. Therefore, when the loop body 300 is switched from the first state to the second state, the elastic member 200 is switched from the state of abutting against the stopper surface 311 to the state of separating the elastic member 200 from the stopper surface 311. Specifically, after the loop body 300 receives the pulling force from the mounting cavity 110 to the direction outside the mounting cavity 110, the pulling force can overcome the mutual supporting force of the elastic element 200 and the limiting surface 311, so that the elastic element 200 slides relative to the limiting surface 311, at this time, the elastic element 200 is deformed or further deformed by the acting force of the limiting surface 311, and the restoring deformation force or the increased restoring deformation force of the elastic element 200 acts on the limiting surface 311, so that the mutual supporting force of the elastic element 200 and the limiting surface 311 is greater, and therefore, the pulling force needs to be further lifted until the elastic element 200 is separated from the limiting surface 311.

Because the limiting surface 311 intersects with the plug-in port 120 of the base 100, the direction that the limiting surface 311 moves out of the mounting cavity 110 from the inside of the mounting cavity 110 to the outside of the mounting cavity 110 is also intersected with the loop body 300, so that the elastic piece 200 can slide along the limiting surface 311 inclined towards the opposite plug-in port 120, the limiting surface 311 can play a role of guiding the elastic piece 200, so that the elastic piece 200 can slide along the limiting surface 311 relatively smoothly, the limiting surface 311 can also guide the elastic piece 200 to deform in a natural transition manner in the process that the elastic piece 200 slides along the limiting surface 311, and the elastic piece 200 is prevented from being severely deformed to cause the elastic piece 200 and the limiting surface 311 to be blocked mutually, thereby enabling the elastic piece 200 to be separated from the limiting surface 311 more easily, and finally enabling the loop body 300 to be moved out of the mounting cavity 110 of the base 100 more easily. In addition, the restoring deformation force of the elastic element 200 makes the mutual propping force of the elastic element 200 and the limiting surface 311 larger, so that the propping effect of the elastic element 200 and the limiting surface 311 is more stable and reliable, and the pulling force also needs to overcome the restoring deformation force of the elastic element 200 to enable the elastic element 200 to slide relative to the limiting surface 311 until being separated, so that the structure is more stable when the loop main body 300 in the loop assembly is in the first state.

In some embodiments, referring to fig. 3, the number of the elastic members 200 may be set to be plural, and the number of the limiting surfaces 311 of the loop body 300 may be set to correspond to the number of the elastic members 200, so that the plurality of elastic members 200 may respectively cooperate with the plurality of limiting surfaces 311, so that when the loop body 300 is in the first state, the plurality of portions of the limiting surfaces 311 of the loop body 300 and the elastic members 200 have a mutual abutting force, so that the loop body 300 is more stable and reliable.

Specifically, the number of the elastic members 200 may be two, and correspondingly, the number of the limiting surfaces 311 of the loop body 300 may be two, and the two limiting surfaces 311 may be distributed on opposite sides of the loop body 300, and correspondingly, the two elastic members 200 may be disposed on two opposite inner walls of the mounting cavity 110. When the two elastic members 200 and the two limiting surfaces 311 are abutted against each other, if the loop body 300 receives a pulling force for pulling the loop body to the outside of the mounting cavity 110 of the base 100, the abutment force of the elastic members 200 received on both sides of the loop body 300 can prevent the loop body 300 from moving to the outside of the mounting cavity 110, so that the loop body 300 can be balanced in force to prevent the situation that one side of the loop body 300 is stable and the other side is deflected. Of course, in other embodiments, the number of the elastic members 200 and the limiting surfaces 311 may be four, the four limiting surfaces 311 may be distributed on the upper, lower, left and right side walls of the loop body 300, and the four elastic members 200 may be correspondingly distributed on the upper, lower, left and right inner walls of the mounting cavity 110, so that the effect of abutting the loop body 300 and the elastic members 200 is stable and reliable.

In some embodiments, referring to fig. 4, in order to make the abutting effect of the elastic element 200 and the limiting surface 311 of the loop body 300 more reliable, the limiting surface 311 may be specifically configured as an arc surface, where the arc surface is disposed towards the socket 120 of the base 100, and the transition of the limiting surface 311 with an arc surface structure in the direction from one end to the other end is more natural. When the elastic member 200 abuts against the limiting surface 311 with the cambered surface structure, the elastic member 200 can move more smoothly relative to the limiting surface 311, so that the elastic member 200 can be separated from the limiting surface 311 more smoothly when the loop body 300 receives the acting force which can separate the limiting surface 311 from the elastic member 200, and the elastic member 200 is further prevented from being damaged due to severe deformation. In addition, when the position that elastic piece 200 and spacing face 311 of this application support is sharp structure, the spacing face 311 that is the cambered surface still can disperse the effort on spacing face 311 is located to the direct pressure of sharp part of elastic piece 200, and the area of contact of elastic piece 200 and spacing face 311 is bigger this moment to damage when can prevent effectively that elastic piece 200 and spacing face 311 support each other, in order to play the purpose of protecting spacing face 311 of elastic piece 200 and return ring main part 300.

In some embodiments, when the limiting surface 311 of the loop body 300 of the present application is in a cambered surface structure, the limiting surface 311 may be arranged to protrude in a direction opposite to the loop body 300, so that the limiting surface 311 presents a convex structure on the outer wall of the loop body 300, when the elastic member 200 is in contact with the limiting surface 311, the contact part of the elastic member 200 and the limiting surface 311 is more likely to be in a state close to the tangent with the limiting surface 311, so that the acting force of the part of the elastic member 200, which is in contact with the limiting surface 311, to the limiting surface 311 is too concentrated, thereby avoiding damage to the elastic member 200 and the limiting surface 311 when the elastic member 200 is in contact with the limiting surface 311.

In some embodiments, referring to fig. 4, the elastic member 200 of the present application has a first end 210 and a second end 220, the first end 210 of the elastic member 200 is connected with the inner wall of the installation cavity 110 of the base 100, and the second end 220 of the elastic member 200 is separable from the inner wall of the installation cavity 110, so that the distance between the second end 220 of the elastic member 200 and the inner wall of the installation cavity 110 can be changed under stress, specifically, when the elastic member 200 is in a natural state, the second end 220 of the elastic member 200 is separated from the inner wall of the installation cavity 110. The elastic member 200 may be a structural member having elasticity, or may be elastically connected to the base 100, so that the second end 220 of the elastic member 200 may move relative to the inner wall of the mounting cavity 110, which is not limited in this application with respect to the specific structural type of the elastic member 200. When the loop body 300 is in the first state, the second end 220 of the elastic member 200 can abut against the limiting surface 311 of the loop body 300, so that the elastic member 200 and the loop body 300 can be fixed and limited.

In some embodiments, referring to fig. 4, the elastic member 200 of the present application may specifically adopt a sheet structure, where the elastic member 200 of the sheet structure has a thinner thickness, so that the structure of the elastic member 200 is relatively more compact, and thus, the space occupied by the elastic member 200 in the mounting cavity 110 is smaller, so that the structure of the base 100 is also more compact, and finally, the structure of the loop assembly of the present application is more compact. At the same time, the elastic member 200 of the sheet structure has relatively greater elasticity, so that the second end 220 of the elastic member 200 can be more easily moved relative to the inner wall of the mounting cavity 110 by the force. It should be understood that when the elastic member 200 is in a sheet structure, the end surface of the second end 220 of the elastic member 200 is relatively narrow, so that the second end 220 of the elastic member 200 is relatively sharp. When the limiting surface 311 in the application adopts the cambered surface protruding along the direction of the loop body 300, when the end surface of the second end 220 of the elastic piece 200 of the sheet structure contacts with the limiting surface 311, the side surface connected with the end surface of the second end 220 on the elastic piece 200 can also contact with the limiting surface 311, and the limiting surface 311 can disperse the acting force of the second end 220 of the elastic piece 200, so that the second end 220 of the elastic piece 200 can be prevented from directly cutting the limiting surface 311, and the elastic piece 200 and the loop body 300 can be prevented from being damaged.

In some embodiments, in order to make the effect of fixing the loop body 300 in the mounting cavity 110 more reliable when the loop body 300 is in the first state, the elastic member 200 may be in a stressed deformed state at this time, specifically, the second end 220 of the elastic member 200 is offset relative to the second end 220 of the elastic member 200 in a natural state when the loop body 300 is in the first state. At this time, the elastic member 200 is deformed by force, so that the restoring deformation force of the elastic member 200 can act on the limiting surface 311 of the loop body 300, so that the second end 220 of the elastic member 200 can be pressed against the limiting surface 311, so that a part of component force of the acting force of the elastic member 200 pressed against the limiting surface 311 can be propped against the limiting surface 311, so that the mutual propping force of the elastic member 200 and the limiting surface 311 is larger, and the loop body 300 can be more stable when the loop body 300 is in the first state and the loop body 300 is in the mounting cavity 110.

In addition, when the elastic member 200 is pressed against the loop body 300, the elastic member 200 can apply pressure to the loop body 300 in a direction toward the loop body 300, so that the loop body 300 is further clamped by the elastic clamp, and the loop body 300 can be more stable and reliable. When the number of the elastic members 200 and the number of the limiting surfaces 311 are two, the two elastic members 200 can apply opposite pressure to the loop body 300, so that the loop body 300 is clamped between the two elastic members 200 by the two elastic members 200, and thus the stress on both sides of the loop body 300 is balanced, and the loop body 300 can be balanced and stable when being positioned in the mounting cavity 110 of the base 100.

In some embodiments, referring to fig. 6, in order to prevent the elastic member 200 of the present application from being damaged due to mutual compression when being abutted against the stop surface 311 of the loop body 300, the second end 220 of the elastic member 200 may be provided with a contact surface 221 abutted against the stop surface 311, that is, when the loop body 300 is in the first state, the contact surface 221 is in contact with the stop surface 311. The contact surface 221 may specifically be an arc surface, so that the contact surface 221 has a relatively larger area, so that the pressure between the contact surface 221 and the limiting surface 311 is smaller after the contact surface 221 and the limiting surface 311 are mutually abutted, and further the contact surface 221 and the limiting surface 311 can be prevented from being damaged due to mutual abutment. Specifically, when the limiting surface 311 is a cambered surface, the contact surface 221 may be a cambered surface matched with the limiting surface 311, that is, when the limiting surface 311 is a convex cambered surface, the contact surface 221 may be a concave cambered surface, so that the contact surface 221 and the limiting surface 311 are in contact with each other more fully.

In addition, in other embodiments, the limiting surface 311 of the loop body 300 may be configured to be planar, and correspondingly, the contact surface 221 of the elastic member 200 may be configured to be planar, so that the contact surface 221 may also be attached to the limiting surface 311.

In some embodiments, referring to fig. 4 and 5, it should be understood that the larger the size of the elastic member 200, the stronger the corresponding elasticity, so the elastic member 200 of the present application may be disposed in a direction from the first end 210 to the second end 220 with a longer size, so that when the elastic member 200 abuts against the limiting surface 311, the mutual abutting force between the elastic member 200 and the limiting surface 311 is stronger, so that the loop body 300 is more stable. When the loop body 300 of the present application is in the first state, the angle between the direction from the first end 210 to the second end 220 of the elastic member 200 and the socket 120 of the base 100 may be set to be smaller than 90 degrees, if the inner wall of the mounting cavity 110 of the base 100 is a plane parallel to the direction of the socket 120, the angle between the direction from the first end 210 to the second end 220 of the elastic member 200 and the inner wall of the mounting cavity 110 may be set to be smaller than 90 degrees, so that when the direction from the first end 210 to the second end 220 of the elastic member 200 has a longer dimension, the space in the mounting cavity 110 occupied by the elastic member 200 is also smaller, so that the space of the mounting cavity 110 of the base 100 does not need to be set too large, and finally the structure of the base 100 is compact.

Specifically, the first end 210 of the elastic member 200 is adjacent to the socket 120 of the base 100, and the second end 220 of the elastic member 200 is far away from the socket 120 of the base 100, so that when the loop body 300 extends into the mounting cavity 110 from the socket 120 of the base 100, the limiting surface 311 of the loop body 300 is opposite to the second end 220 of the elastic member 200, so that the second end 220 of the elastic member 200 can abut against the limiting surface 311.

When the loop body 300 is in the first state, the second end 220 of the elastic member 200 abuts against the limiting surface 311 of the loop body 300, so that at least a portion of the elastic member 200 is opposite to the outer wall of the loop body 300 where the limiting surface 311 is disposed. The outer wall of the limiting surface 311 of the loop body 300 is further provided with an avoidance groove 312, when the loop body 300 is in the first state, at least part of the elastic member 200 can be located in the avoidance groove 312, so that the clearance space between the elastic member 200 and the loop body 300 is smaller, the elastic member 200 and the loop body 300 can be closer to each other, and finally the structure of the loop assembly is more compact.

Therefore, when the loop body 300 is not inserted into the installation cavity 110, or at least a portion of the loop body 300 is inserted into the installation cavity 110, but the loop body 300 is not moved to be opposite to the elastic member 200, the elastic member 200 is in a natural state, at least a portion of the elastic member 200 is located in a moving direction of the loop body 300, the elastic member 200 is pressed after the loop body 300 continues to move toward the installation cavity 110, so that the second end 220 of the elastic member 200 moves toward the inner wall of the installation cavity 110, and when the loop body 300 moves to the dodging groove 312 to be opposite to the elastic member 200, the restoring deformation force of the elastic member 200 drives at least a portion of the elastic member 200 to move into the dodging groove 312.

Referring to fig. 4, a relief surface 312a may also be disposed in the relief groove 312, where the relief surface 312a is opposite at least a portion of the elastic member 200, and correspondingly, the relief surface 312a is opposite an inner wall of the mounting cavity 110 that is connected to the first end 210 of the elastic member 200. In the direction facing away from the plug-in port 120 of the base 100, that is, in the plug-in direction of the loop body 300 inserted into the mounting cavity 110 from the plug-in port 120, the distance between the avoidance surface 312a and the inner wall of the elastic member 200 arranged in the mounting cavity 110 may be gradually increased, that is, the avoidance surface 312a intersects with the direction of the plug-in port 120, so that the space between the inner wall of the elastic member 200 arranged in the mounting cavity 110 and the avoidance surface 312a is gradually increased, and thus, the elastic member 200 may be attached to the avoidance surface 312a in the direction from the first end 210 to the second end 220, and when the elastic member 200 is clamped on the loop body 300, the contact area between the elastic member 200 and the loop body 300 is larger, so that the friction force between the elastic member 200 and the loop body 300 may be increased, and the contact between the loop body 300 and the elastic member 200 may be more stable and reliable.

In some embodiments, it should be understood that, since the limiting surface 311 and the avoiding surface 312a on the loop body 300 are both intersected with the plug 120 of the base 100, if the limiting surface 311 and the avoiding surface 312a are directly connected, there is no transition at the connection between the two, which may further result in complex processing of the loop body 300. Therefore, referring to fig. 4, in order to reduce the difficulty of the preparation process of the loop body 300 in the present application, the outer wall of the loop body 300 may further be provided with a transition surface 313, where the transition surface 313 is located between the limiting surface 311 and the avoiding surface 312a, two ends of the transition surface 313 are connected with the limiting surface 311 and the avoiding surface 312a respectively, the transition surface 313 is parallel to the direction of the plug-in port 120 of the base 100, so that the connection between the transition surface 313 and the limiting surface 311 and the connection between the transition surface 313 and the avoiding surface 312a are all transitional naturally, thereby reducing the difficulty of the preparation process of the loop body 300.

In some embodiments, referring to fig. 1, the elastic member 200 and the base 100 of the present application may be integrally formed, so that the connection reliability between the elastic member 200 and the base 100 is better. Specifically, the base 100 may be made of a non-metal composite material or a metal material, and the outer wall of the base 100 is cut to separate the elastic member 200 from the outer wall of the base 100, three sides of the elastic member 200 are separated from the base 100, and one side of the elastic member 200 is connected to the base 100.

The connection port 314 of the housing 310 may be an opening structure or a transparent area structure on the housing 310, which is not limited in this application.

In some embodiments, referring to fig. 7, when the loop body 300 is positioned in the mounting cavity 110 of the base 100, in order to facilitate the user to insert and withdraw the loop body 300, the loop body 300 may further include a handle 330, the handle 330 being connected with the housing 310, and the user may insert and withdraw the loop body 300 by holding the handle 330.
