[0027] In the following description, if it is indicated to refer to a specific figure or as shown in a specific figure, it is only used to emphasize that most of the relevant content appears in the subsequent description, but it does not limit the subsequent description to only refer to the specific figure.

[0028] Please also read Figures 1 to 6 The connector 100 of the present invention is used for plugging with the docking connector 200. The docking connector 200 includes a docking locking structure 201. The connector 100 includes: a connecting body 1, a shell 2, an elastic arm 3, a drawstring 4 and a locking structure 5.

[0029] One end of the connection body 1 has a docking interface. The connection body 1 is an insulating structure. In this embodiment, the docking interface is a plurality of hollow cylindrical structures 11. The connector 100 can be plugged with the docking connector 200 along the docking direction D1.

[0030] One side of the connecting body 1 has a locking structure 5. The locking structure 5 can be deformed by force, and in the locked state (such as Figure 7 ) and unlocked state (as shown Figure 8 ) to engage or separate with the docking locking structure 201 of the docking connector 200. In practical applications, the connecting body 1 and the locking structure 5 are integrally formed.

[0031] The locking structure 5, for example, includes an actuating arm 51 and (two) supporting structures 52, and the actuating arm 51 is, for example, an elastic sheet structure. The substantially middle position of the actuating arm 51 is connected to the connecting body 1 through the supporting structure 52, and one end of the locking structure 5 can be pressed to elastically deform in a direction close to the connecting body 1. When one end of the locking structure 5 is pressed and elastically deformed in a direction close to the connecting body 1, the other end of the locking structure 5 will correspondingly elastically deform in a direction away from the connecting body 1. In different embodiments, in order to strengthen the fixation, the locking structure 5 can also be fixed to the connecting body 1 not only through a single supporting structure 52. In different embodiments, the locking structure 5 can also be fixed to the connecting body 1 through a single supporting structure 52.

[0032] The actuating arm 51 of the locking structure 5 faces the inner side of the connecting body 1 and has a snap-fit ​​structure 511. The snap-fit ​​structure 511 is a groove (or a protrusion), and the docking locking structure 201 is, for example, a protrusion (or a groove); the snap-fit ​​structure 511 can be snap-fitted with the docking locking structure 201. The connector 100 is snap-fitted with the docking locking structure 201 of the docking connector 200 through the locking structure 5.

[0033] One end of the shell 2 is connected to the connecting body 1. The shell 2 may include, for example, a body 21, a cover 22 and an elastic arm 3. The top of the body 21 is connected to the elastic arm 3, and the cover 22 is detachably disposed on the other side of the body 21. The body 21 and the elastic arm 3 may be integrally formed. The side walls 211 included in the body 21 may be respectively formed with at least one wire outlet hole 2111, and the wire outlet hole 2111 is used to provide a plurality of cables (not shown) connected to the connecting body 1 to pass through. In this embodiment, it is taken as an example that both the two side walls 211 of the body 21 and the cover 22 have wire outlet holes 2111, but the number of the wire outlet holes 2111 included in the body 21 and their setting positions can be adjusted according to needs.

[0034] The design that the cover 22 can be detachably connected to the main body 21 can facilitate the maintenance and replacement of the connecting body 1 by relevant personnel. The cover 22 is detachably fixed to the main body 21 in a direction different from the docking direction D1, and the main body 21, the elastic arm 3 and the connecting structure 33 (described in detail later) are integrally formed. In addition, by setting the elastic arm 3 and the connecting structure 33 on the main body 21, and fixing one end of the pull strap 4 on the connecting structure 33, and the other end of the pull strap 4 passing through the wall hole 2121 of the rear wall 212 and out of the main body 21, the pull strap 4 and the elastic arm 3 will not be affected during the replacement, maintenance and assembly of the connecting body 1 by relevant personnel.

[0035] like Figure 5As shown, in actual application, the cover body 22 may, for example, include two first connecting structures 222 (perforations or protrusions) and two second connecting structures 223 (protrusions or perforations), and the two first connecting structures 222 may be mutually engaged with two first pairs of card structures 214 (protrusions or perforations) of the main body 21 along a first direction D2, and the two second connecting structures 223 may be mutually engaged with two second pairs of card structures 215 (perforations or protrusions) of the main body 21 along a second direction D3, and the first direction D2 is different from the second direction D3.

[0036] The first direction D2 and the second direction D3 are perpendicular to each other, and the first direction D2 is perpendicular to the pulling direction of the drawstring 4, while the second direction D3 is parallel to the pulling direction of the drawstring 4. The cover 22 has a wire outlet hole 221, and the wire outlet hole 221 of the cover 22 is also used to provide at least one cable connected to the connecting body 1 to pass through.

[0037] As described above, by designing the main body 21 and the cover 22 with the wire outlet holes 2111 and 221 , relevant personnel can make the cables connected to the main body 1 pass through the housing 2 in different directions according to actual wire outlet requirements.

[0038] The two ends of the elastic arm 3 are a connecting end 31 and a free end 32. The connecting end 31 of the elastic arm 3 is connected to the body 21 of the housing 2. The elastic arm 3 can be subjected to external force to elastically deform relative to the body 21. The inner side of the elastic arm 3 has a connecting structure 33. The connecting structure 33 is an L-shaped structure. The free end 32 of the elastic arm 3 is located above the locking structure 5.

[0039] One end of the drawstring 4 has a first through hole 41, and the drawstring 4 is sleeved on the connection structure 33 through the first through hole 41, thereby being fixed to the connection structure 33. The other end of the drawstring 4 passes through the wall hole 2121 on the rear wall 212. When the drawstring 4 is pulled and moves away from the housing 2, the end of the drawstring 4 connected to the connection structure 33 will drive the free end 32 of the elastic arm 3 to elastically deform in a direction close to the body 21.

[0040] like Figure 7 and Figure 8 As shown, when the pull strap 4 is pulled in the direction away from the shell 2, the end of the pull strap 4 connected to the connecting structure 33 will drive the elastic arm 3 so that the free end 32 of the elastic arm 3 presses against one end of the locking structure 5, whereby the other end of the locking structure 5 will elastically deform in the direction away from the connecting body 1, and the locking structure 511 of the locking structure 5 will no longer be engaged with the docking locking structure 201 of the docking connector 200, and the connector 100 will be unlocked from the docking connector 200.

[0041] When the locking structure 5 of the connector 100 and the docking locking structure 201 are unlocked, the user can continue to pull the pull strap 4 to separate the connector 100 from the docking connector 200. Of course, when the locking structure 5 and the docking locking structure 201 are unlocked, the user can also directly pull the connector 100 away from the docking connector 200 by holding the connector 100.

[0042] like Figure 6 and Figure 7 As shown, in a preferred embodiment, the rear wall 212 of the body 21 may also have a limiting structure 213, and the limiting structure 213 is located in the wall hole 2121. The limiting structure 213 includes a head 2131 and a neck 2132. The width of the head 2131 is greater than the width of the neck 2132. The head 2131 is connected to one end of the neck 2132 to form the limiting structure 213, and the other end of the neck 2132 is connected to the rear wall 212. The size of the head 2131 is slightly larger than the size of the second through hole 42 of the drawstring 4, while the size of the neck 2132 is smaller than the size of the second through hole 42.

[0043] The limiting structure 213 is used to limit the range of movement of the drawstring 4 in the wall hole 2121. Specifically, when the second through hole 42 of the drawstring 4 is sleeved in the limiting structure 213, when the drawstring 4 is pulled away from the body 21, the head 2131 will limit the drawstring 4 to prevent the drawstring 4 from escaping from the wall hole 2121.

[0044] like Figure 6 and Figure 7 As shown, when the drawstring 4 is not pulled and the inner wall of the first through hole 41 of the drawstring 4 abuts against the connecting structure 33 , a gap G is generated between the limiting structure 213 and the second through hole 42 of the drawstring 4 .

[0045] like Figure 7 and Figure 8 As shown, when the pull strap 4 is pulled and the pull strap 4 drives the elastic arm 3 to press the locking structure 5, the inner side wall of the second through hole 42 of the pull strap 4 will abut against the limiting structure 213. At this time, if the pull strap 4 is continuously pulled, the inner side wall of the first through hole 41 and the inner side wall of the second through hole 42 of the pull strap 4 will be driven together, and the connector 100 will move away from the docking connector 200.

[0046] That is to say, Figure 7 As shown, when the locking structure 5 of the connector 100 and the docking locking structure 201 of the docking connector 200 are engaged with each other, the user pulls the drawstring 4 to move the drawstring 4 toward Figure 7When moving in the right direction as shown, the end of the pull strap 4 having the first through hole 41 will drive the elastic arm 3 to press the locking structure 5 through the connecting structure 33, so that the locking structure 5 and the docking locking structure 201 are no longer engaged with each other. Then, the user continues to pull the pull strap 4, and the pull strap 4 will drive the connector 100 to separate from the docking connector 200.

[0047] As described above, by allowing the pull strap 4 to be sleeved on the limiting structure 213 and the gap G through the second through hole 42, the user can directly and continuously pull the pull strap 4 to unlock and separate the connector 100 and the docking connector 200, and in this process, the pull strap 4, the elastic arm 3 and the connecting structure 33 are not prone to breakage.

[0048] like Figure 7 As shown, in one of the specific embodiments, the straight-line distance L1 between the position where the connecting structure 33 is connected to the elastic arm 3 and the connecting end 31 of the elastic arm 3 is smaller than the straight-line distance L2 between the position where the connecting structure 33 is connected to the elastic arm 3 and the free end 32, that is, the connecting structure 33 is arranged close to the connecting end 31 of the elastic arm 3. Such a design allows the user to drive the elastic arm 3 to press against the locking structure 5 with a relatively small pulling force. In addition, in the embodiment where the overall height of the housing 2 is greater than 7 cm, the straight-line distance L3 between the position where the elastic arm 3 is used to press against the locking structure 5 and the position where the elastic arm 3 is connected to the housing 2 can be between 7 and 20 cm.

[0049] Please refer to Figure 1 In one specific embodiment, the outer side surface 3A of the elastic arm 3 can be flush with the outer side surface 2A of the main body 21, and the area of ​​the wire outlet hole 2111 located on the side wall 211 of the main body 21 can account for 65 to 90 percent of the total area of ​​the side wall 211. Such a design allows the cable connected to the main body 1 to better pass through the wire outlet hole 2111 and out of the shell 2.

[0050] As described above, the connector 100 of the present invention is designed with a pull strap 4, an elastic arm 3, a connection structure 33 and a locking structure 5, so that the user can simply pull the pull strap 4 to unlock the locking structure 5 of the connector 100 from the docking locking structure 201 of the docking connector 200 and then separate it from the docking connector 200.

[0051] Please also read Figures 9 to 13One difference between this embodiment and the previous embodiment is that the outer side surface 3A of the elastic arm 3 protrudes from the outer side surface 2A of the shell 2, that is, the outer side surface 3A of the elastic arm 3 is not flush with the outer side surface 2A of the shell 2. The inner side of the elastic arm 3 also has a stop structure 34, which is arranged adjacent to the connection structure 33. The stop structure 34 is used to limit the range of movement of the drawstring 4 engaged with the connection structure 33 to prevent the drawstring 4 from leaving the connection structure 33. Another difference between this embodiment and the previous embodiment is that the wall hole 2121 located on the rear wall 212 of the shell 2 is arranged close to the side where the shell 2 is connected to the elastic arm 3, and the shell 2 does not have a limiting structure 213 in the wall hole 2121.

[0052] In summary, the connector 100 of the present invention allows the user to simply and quickly unlock and separate the connector 100 from the docking connector 200 by pulling the pull strap 4 .

[0053] The above description is only a preferred feasible embodiment of the present invention, and does not limit the patent scope of the present invention. Therefore, all equivalent technical changes made using the contents of the present invention description and drawings are included in the protection scope of the present invention.
