[0057] In order to explain the technical content, structural features, achieved objectives and effects of the technical solution in detail, the following is a detailed description in conjunction with specific embodiments and accompanying drawings.

[0058] See also Figures 1 to 8 The utility model provides a terminal cage 20, a straight-plug type connector pin 2 and a connector, wherein the terminal cage 20 is a component of the straight-plug type connector pin 2, and is used to detachably fix the cable, especially the cable can be conveniently fixed outside the terminal cage 20 by hand; the straight-plug type connector pin is a component of the connector, and is used to guide the current carried by the cable to the electrical appliance when the connector connects the cable and the electrical appliance together.

[0059] See also Figure 1 and Figure 2 In a specific embodiment, the terminal cage 20 includes a cage body 200 and a wire-pressing elastic member. The cage body 200 is used to place the wire-pressing elastic member and fix the cable together with the wire-pressing elastic member, and after fixing the cable, guide the current carried by the cable; in order to facilitate the installation of the cable, the cage body 200 is in a long strip shape, which can collect more cables and ensure that the cable is more stable when fixed by the wire-pressing elastic member. The wire-pressing elastic member is used to press the cable to ensure that the cable is in contact with the cage body 200, so that the cage body 200 can conduct the current carried by the cable.

[0060] The cage body 200 includes a top plate and a bottom plate, a cavity is formed between the top plate and the bottom plate, and is used to accommodate the wire pressing elastic member and the cable. A wire insertion port 2001 is provided between the top plate and the bottom plate, and the cable can enter the cavity through the wire insertion port 2001. The size of the wire insertion port increases from the inside of the cage body to the outside of the cage body, that is, the wire insertion port 2001 is trumpet-shaped, and such a setting facilitates the insertion of the cable into the cage body 200.

[0061] One end of the wire pressing elastic member is a fixed end 2012, and the other end of the wire pressing elastic member is a movable end 2011. The wire pressing elastic member is compressed and arranged between the top plate and the bottom plate of the cage body, so that the wire pressing elastic member can be in a state of storing elastic potential energy. The fixed end 2012 is connected to the top plate, and the wire pressing elastic member can be fixedly connected to the cage body; the movable end 2011 abuts against the bottom plate under the action of its own elastic force, and the movable end 2011 can move in the opposite direction of the elastic force under the action of external force, and can also avoid the entire wire pressing elastic member from deviating from the set position in other directions during the movement of the movable end 2011.

[0062] A boss 2010 is provided on the side of the movable end 2011, and the boss 2010 is connected to the movable end 2011 as a whole; the boss passes through the outside of the cage body and can swing along the direction of the elastic force applied to the movable end.

[0063] In order to ensure the stability of the installation of the wire pressing elastic member, in a certain embodiment, the cage body is further provided with a first side plate, which is provided between the top plate and the bottom plate and connected to the top plate and the bottom plate of the cage body. Specifically, the first side plate can be provided on the side of the wire pressing elastic member where the boss is not provided, and the side of the wire pressing elastic member where the boss is not provided leans against the first side plate, thereby improving the stability of the wire pressing elastic member.

[0064] In another embodiment, the first side plate can also be arranged on the side of the wire pressing elastic member provided with the boss, and the first side plate is provided with a slot 2003 along the direction of the elastic force received by the movable end; the boss passes through the slot to the outside of the cage body and can move along the slot. The side of the wire pressing elastic member provided with the boss leans against the first side surface, and the stability of the wire pressing elastic member can also be improved. By providing the slot, not only the first side plate will not affect the swing of the boss, but also it can play a guiding role for the boss, so that the boss can move along a predetermined trajectory, thereby improving the stability of the wire pressing elastic member when subjected to external force.

[0065] Based on the above arrangement, in a further embodiment, the cage body is further provided with a second side plate, which is located on the side of the wire pressing elastic member where no boss is provided, and is connected to the top plate and the bottom plate of the cage body. The side of the wire pressing elastic member where no boss is provided leans against the second side plate. At this time, the second side plate, the first side plate, the top plate, and the bottom plate together form a cavity, and the first side plate, the second side plate, the top plate, and the bottom plate are all side walls of the cavity.

[0066] When the movable end 2011 needs to be moved, it is only necessary to manually control the boss 2010 located outside the cage body 200 to move along the slot 2003. If the movable end 2011 needs to be separated from the bottom plate of the cage body, the boss 2010 can be pressed in the opposite direction of the elastic force on the movable end 2011, so that the boss 2010 can move the movable end 2011 in the opposite direction of the elastic force on the movable end 2011. During this process, the wire-pressing elastic member continues to store elastic potential energy. After that, if the movable end 2011 needs to be restored to a state against the bottom plate of the cage body, it is only necessary to release the boss 2010, the wire-pressing elastic member releases the elastic potential energy, and the movable end 2011 will move in the direction of the elastic force on the movable end 2011 under the action of the elastic force until the movable end 2011 completely presses against the bottom plate of the cage body. In this way, there is no need to use other tools for operation. It is only necessary to control the boss 2010 protruding outside the cage body 200. It will not be restricted by the space of the cage body, and the wire-pressing elastic part can be easily moved. In addition, the boss 2010 is connected to the wire-pressing elastic part as a whole. During production and installation, it is not necessary to be independent of the wire-pressing elastic part and then installed separately in the cage body 200, which reduces the difficulty of production and installation.

[0067] When in use, first press the boss 2010 by hand to move the boss 2010 in the opposite direction of the elastic force on the movable end 2011, so that the movable end 2011 is separated from the bottom plate of the cage, and the separation distance is the distance that the cable can pass through; if it is to insert the line, insert the cable into the cage 200 from the wire insertion port 2001, and pass it through the gap between the movable end 2011 and the bottom plate of the cage, finally, release the boss 2010, and the movable end 2011 will move in the direction of the elastic force under the action of the elastic force until the cable is completely pressed between the movable end 2011 and the bottom plate of the cage; if it is to withdraw the line, pass the cable from the gap between the movable end 2011 and the bottom plate of the cage, then withdraw it from the wire insertion port 2001, and finally, release the boss 2010.

[0068] In one embodiment, the plug port 2001 is arranged at one end face of a cavity formed by the second side panel, the first side panel, the top panel, and the bottom panel, and the end panel can be arranged at the other end face of the cavity formed by the second side panel, the first side panel, the top panel, and the bottom panel. When the cage 200 is produced, the initial shape of the cage 200 can be cut into an unfolded shape of a rectangular parallelepiped with only five faces. When the cage 200 is assembled, the unfolded cage 200 can be directly folded into a three-dimensional shape with a cavity, which can facilitate the production of the cage 200.

[0069] The fixed end 2012 of the wire pressing elastic member can be fixed to the top plate of the cage body by welding or screws. Since the space in the cage body 200 is limited, such a fixing method is difficult to use during production and is not convenient for replacing the wire pressing elastic member. Figure 3 and Figure 4 , in a preferred embodiment, a limiting block 2002 is provided on the top plate of the cage body, and a limiting groove 2014 is opened at the fixed end; the fixed end is clamped at the limiting block 2002 through the limiting groove 2014. When installing the wire-pressing elastic member, it is only necessary to compress the wire-pressing elastic member in advance, and then push the compressed wire-pressing elastic member into the cavity until the limiting groove 2014 of the fixed end 2012 is opposite to the limiting block 2002 on the top plate of the cage body, and then press the fixed end 2012 in the direction of the limiting block 2002, so that the limiting block 2002 is clamped in the limiting groove 2014, so that the fixed end 2012 is fixedly connected to the top plate of the cage body. When it is necessary to replace the wire-pressing elastic member, the fixed end 2012 can be pulled forcefully, so that the limiting block 2002 is separated from the limiting groove 2014, and then the wire-pressing elastic member can be taken out of the cavity. Therefore, this can not only connect the fixed end 2012 to the top plate of the cage body, but also facilitate the installation of the wire-pressing elastic member and the disassembly of the wire-pressing elastic member.

[0070] In an embodiment, the wire-pressing elastic member is a spring piece 201; the fixed end 2012 is one end of the spring piece 201, and the movable end 2011 is the other end of the spring piece 201; the width of the movable end 2011 is adapted to the width of the cavity of the cage body 200, so that the spring piece 201 can not only be placed in the cavity of the cage body 200, but also can tightly press the cables connected into a whole bundle, and can tightly install each cable of the loose wires. The movable end 2011 is elastically bent to face the fixed end 2012. When the spring piece 201 is arranged in the cavity of the cage body 200, the movable end 2011 will be subjected to an elastic force in the direction away from the fixed end 2012, that is, the movable end 2011 will abut against the inner wall of the cavity of the cage body 200 under the action of the elastic force.

[0071] In order to have enough space for the cable to pass through between the movable end 2011 and the bottom plate of the cage body 200 after the movable end 2011 is moved in the direction close to the fixed end 2012, in an embodiment, the spring piece 201 can be a V-shaped spring piece, and the V-shaped spring piece only includes the fixed end 2012 and the movable end 2011; the spring piece can also be a C-shaped spring piece, and the elastic force received by the movable end 2011 comes from the elastic force between the middle part of the spring piece and the movable end 2011.

[0072] In a preferred embodiment, the middle part 2013 of the spring piece 201 is bent into a U shape. Such a spring piece 201 has stronger toughness and stronger elastic force, and can better provide a stronger and more stable pressing force for the movable end 2011 to press the cable.

[0073] In order to facilitate the cable to pass through the gap between the movable end 2011 and the top plate of the cage, in a preferred embodiment, the bending direction of the movable end 2011 is opposite to the wire insertion port 2001, and the movable end 2011 is inclined in the direction away from the fixed end 2012. Such a setting allows the movable end 2011 to play a guiding role, which is convenient for the installation of the cable. It also makes the direction of the elastic force on the movable end 2011 the same as the direction of the component force applied to the movable end 2011 when the cable is pulled out. If the cable is pulled out by mistake, the external force applied by the cable on the movable end 2011 will increase the force of the movable end 2011 pressing the cable, which can further prevent the cable from detaching.

[0074] When the first side plate is also arranged on the side where the boss is provided on the wire pressing elastic member, and the first side plate is provided with a slot 2003 along the direction of the elastic force exerted on the movable end, in order to facilitate the installation of the wire pressing elastic member, in a certain embodiment, the first side plate is also provided with a mounting hole 2004; the size of the mounting hole 2004 is larger than the size of the wire pressing elastic member; the slot 2003 is connected with the mounting hole 2004; the wire pressing elastic member can be installed in the cavity through the mounting hole 2004, and the boss 2010 can be moved from the mounting hole 2004 to the slot 2003 under the elastic action. When it is necessary to install the wire-pressing elastic member, the wire-pressing elastic member can be compressed first, and then placed horizontally in the cavity of the cage body 200 from the installation hole 2004, and the boss 2010 is opposite to the slot 2003, and then the wire-pressing elastic member is released, and the limit block 2002 is located in the limit groove 2014 of the fixed end 2012. At this time, the fixed end 2012 is pressed to make the limit block 2002 clamped in the limit groove 2014; the movable end 2011 is against the bottom plate of the cage body 200 under the action of elastic force, and the boss 2010 moves to the bottom of the slot 2003 with the movable end 2011, so that the installation of the wire-pressing elastic member is conveniently completed.

[0075] When the spring piece 201 with the middle portion 2013 bent into a U shape is installed in the cavity of the cage 200 through the installation hole 2004, in a certain embodiment, the width of the U-shaped middle portion 2013 of the spring piece 201 can be greater than the width of the cage 200, and at this time, the U-shaped middle portion 2013 of the spring piece 201 can be mounted on the installation hole 2004. In this way, the stability of the fixed end 2012 of the spring piece 201 can be ensured.

The guide can be plate-shaped.

[0077] When multiple cables need to be connected through one needle 21, you can refer to Figure 6 In one embodiment, at least two terminal cages 20 are provided, and each terminal cage 20 is arranged side by side at the guide member 22. In this way, the current carried by multiple cables can be guided through a single needle body 21.

[0078] In a specific embodiment, the connector includes a connector body, and the connector body can be an M8 connector or an M12 connector. Specifically, the connector body includes a housing 1 and a straight-plug connector pin 2; the straight-plug connector pin 2 is any of the straight-plug connector pins described above; one end of the housing 1 is a connector port 10, and the other end of the housing 1 is a wiring port 11; the straight-plug connector pin is arranged in the housing 1, and the head end 211 of the pin body 21 is located at the connector port 10.
