Description

Easy to pull plug

technical field

The utility model relates to a plug, in particular to a plug that is easy to pull out.

Background technique

Generally speaking, after the plug is inserted into the socket, if the plug is to be pulled out from the socket, the correct way to pull it out is that the user must first hold any part of the plug with his hands, and then pull it out. However, since the correct way of pulling out is difficult to pull out, users often directly hold the power cord connected to the plug, and then pull it out to pull out the plug. In this way, it is easy to cause damage or breakage of the power cord.

Referring to FIG. 1 , Taiwan Patent No. M307903 discloses an easy-to-pull plug 1 . The easy-to-pull plug 1 includes a plug body 11 and a pressure rod 12 pivotally connected to the plug body 11 . When wanting to pull out the easy-to-pull plug 1 from the socket (not shown), one end 121 of the pressure rod 12 can be pressed down to pivot one end 121 downward, and at the same time, the other end 122 can be pushed forward against the socket so that the plug body 11 Disengage and pull out in the direction away from the socket.

However, although the above-mentioned easy-to-pull plug 1 can achieve the purpose of saving labor, due to pulling out the easy-to-pull plug 1, the pressure bar 12 must be pressed down, and the user generally only needs to hold any part of the plug first, and then outwards. The pulling-out methods of pulling out are different, and when causing the user to use this easy-to-pull plug 1, it is necessary to change the original pulling-out method, which is relatively inconvenient.

Furthermore, the above connection relationship is not limited to be achieved by the cooperation between the guide groove and the guide post.

Referring to Fig. 6 and Fig. 7, the second preferred embodiment of the easy-to-pull plug 2 of the present utility model is mostly the same as the first preferred embodiment, the main difference is that the connecting rod set 6 includes the first rod 61, A second rod 62 is also included. Wherein, the first rod 61 has a force receiving end 611 and another end 613', and the second rod 62 has an end 621 connected with the other end 613' of the first rod 61 and a resisting end 623.

Referring to Figure 6, it is a schematic diagram of the easy-to-pull plug 2 fully inserted into the socket 7. At this time, the body 3 is flush with the front end of the shell 5 and both abut against the outer surface of the socket 7, and the conductive sheet 4 is completely accommodated in the socket 7. middle.

Referring to Fig. 7, when the easy-to-pull plug 2 is to be pulled out from the socket 7, force is applied to the shell 5 and the shell 5 is moved backward relative to the body 3, and the first guide groove 51 of the shell 5 drives the stressed end of the first rod 61 The first guide column 612 of 611 makes the first rod 61 pivot around the pivot shaft 31 of the body 3, and makes the second guide groove 614 of the other end 613' of the first rod 61 link with the one end 621 of the second rod 62. The second guide post 622 makes the second rod 62 move forward relative to the body 3 under the guidance of the guide part 33 , and finally makes the abutting end 623 of the second rod 62 abut against the socket 7 so that the conductive sheet 4 is separated from the socket 7 . In this embodiment, the guide portion 33 is a guide rail disposed on the body 3 and located on both sides of the second rod 62 .

Same as the first embodiment, in the second embodiment, the linkage set 6 can be pivotally mounted on the body 3 , and can also be pivotally mounted on the casing 5 .

In the aforementioned two embodiments, two situations in which the connecting rod group 6 includes one connecting rod (i.e. the first embodiment) or two connecting rods (i.e. the second embodiment) are disclosed, but the connecting rod group 6 includes The number of rods should not be limited by the foregoing disclosure, as long as the stressed end of the connecting rod group 6 drives the movement of the connecting rod group 6 so that the abutting end abuts against the socket 7 .

To sum up, through the cooperation of the first guide column 612 of the force receiving end 611 of the connecting rod group 6 and the first guide groove 51 of the housing 5, when force is applied to the housing 5 and the housing 5 moves backward relative to the body 3 At this time, the force-bearing end 611 is stressed and the connecting rod group 6 pivots, and then drives the abutting ends 613, 623 of the connecting rod group 6 to push against the socket 7 so that the conductive sheet 4 is separated from the socket 7, and can be pulled out according to the original method. Pull out plug 2 easily, so really can reach the purpose of the present utility model.
