Door.
In the above-described embodiments, it can be the hold-fast body for holding latch 5 tightly by the side wall of latch 5 to extract locking mechanism 4, also may be used
Think including the stopper slot for cooperating and the position limiting structure of spacing preiection, be not specifically limited herein.But, when using above-mentioned
During second scheme, position limiting structure inevitably is set on latch 5, due to the small volume of latch 5 and thinner thickness, because
If this opens up stopper slot or spacing hole on latch 5, the structural strength of latch 5 can be reduced, further, since latch 5 is in grafting
Before in the sleeve 3, need guiding through the jack on cover plate 2, if therefore spacing preiection is set on latch 5, the nothing of latch 5 can be caused
Method is passed through by the jack on cover plate 2.Therefore, in order to avoid above mentioned problem, it is preferred to use above-mentioned the first scheme, that is to say, such as
Shown in Fig. 2, extracting locking mechanism 4 includes inclined-plane set 41 and the floating shelf 42 that can be fluctuated in base 1, and inclined-plane covers 41 shapes
The distance between the relative inclined-plane of the side wall of Cheng Youyu latches 5, inclined-plane and the side wall of latch 5 are gradually reduced from the bottom to top, extract lock
Determining mechanism 4 also includes the friction member 43 for being used to clamp latch 5, and friction member 43 is located between inclined-plane and latch 5, and friction member 43 can live
Dynamic is installed on floating shelf 42, and can be moved up and down along inclined-plane under the drive of floating shelf 42 abutting with the side wall of latch 5 or
Separate, so as to hold latch 5 tightly or be separated with latch 5, it is to avoid the spacing knots such as stopper slot or spacing preiection are set on latch 5
Structure, so as to ensure that the structural strength and grafting validity of latch 5.
Wherein, friction member 43 can be cylindrical structure, or prism structure, can also be cuboidal columnar or ball
Shape structure, is not specifically limited herein.
In addition, inclined-plane set 41 can be fixedly connected with cover plate 2, so that inclined-plane is covered into 41 the bottom of by while cover plate 2 is opened
Removed in seat, thus reduce the dismounting difficulty of socket.And, in order to improve the structural strength of inclined-plane set 41, preferably inclined-plane
Set 41 is made by metal material, and compared to nonmetallic materials, the Stability Analysis of Structures of metal material, intensity is higher, is bearing frequently
Pressure is not easy to be deformed when acting on.
Furthermore, extracting locking mechanism 4 can not inserted by latch 5 by any side side wall locking in the both sides of intermediate plate clamping
Pin 5, it is also possible to by the both sides side wall dead bolt 5 not clamped by intermediate plate on latch 5, be not specifically limited herein.But work as and adopt
During with above-mentioned the first scheme, side side wall dead bolt 5 of the locking mechanism 4 by latch 5, the unilateral stress of latch 5, latch are extracted
5 easily produce flexural deformation.In order to avoid above mentioned problem, it is preferred to use above-mentioned second scheme, specifically, as shown in Fig. 2 tiltedly
The inclined-plane that surface cover 41 is formed is two, and the side wall of two inclined-planes respectively with latch 5 is relative, and friction member 43 is two, and two are rubbed
Part 43 is respectively arranged between two inclined-planes and latch 5, and relative the two of latch 5 thus can be respectively extruded by two friction members 43
Side side wall, now, the opposite sides stress of latch 5, stress is more balanced, and latch 5 thus can be avoided to produce flexural deformation, and latch
5 both sides are subject to enclasping force, therefore are used to prevent latch 5 bigger by the enclasping force deviate from slot.
In the above-described embodiments, inclined-plane set 41 can be that section is the inclined-plane set of " Λ " type, or shape as shown in Figure 9
The inclined-plane set of shape, certainly can also be other shapes, be not specifically limited herein, as long as inclined-plane set 41 be formed with respectively with latch
Two relative inclined-planes of 5 opposite sides side walls, and the distance between two inclined-planes and latch 5 be gradually reduced from the bottom to top.
In order to reduce the height of Anti-disconnecting socket, specifically, when floating shelf 42 is moved downward to extreme lower position in base 1
When, the lower end position of friction member 43 is located at the lower section of the upper end position of the sleeve 3 corresponding to it.Thus, in floating shelf 42 upper
During lower floating, friction member 43 can be moved downward in the altitude range of sleeve 3, so as to reduce the height of Anti-disconnecting socket.
In the embodiment shown in Figure 2, in order to produce interference between two intermediate plates for preventing friction member 43 and formation slot,
Preferably, the side side wall that the locking of locking mechanism 4 can be pulled out on latch 5 is extended transversely into outside slot scope, thus when slotting
Pin 5 is plugged in slot and is pulled out after locking mechanism 4 locks, and in the vertical direction is not between friction member 43 and two intermediate plates

More in line motor inner components, volume and quality are generally larger, therefore are unfavorable for being installed in base 1.Therefore,
In order to avoid above mentioned problem, above-mentioned second scheme can be used, it is specifically, between floating shelf 42 and the bottom wall of base 1 or floating
Elastic component 6 is provided between moving frame 42 and cover plate 2, elastic component 6 can act on a upward elastic force to floating shelf 42, so as to install
In the friction member 43 on floating shelf 42 and latch 5 side wall against now, if extracting latch 5 upwards, friction member 43 is then in friction
There is the trend for moving up in the presence of power and elastic force, but due to the effect of inclined-plane set, friction member 43 more blocks more on inclined-plane
Tightly, and self-locking is formed, latch 5 is drawn out easily from extracting or not allowing, and when needing to extract latch 5, can be by under staff
Pressure floating shelf 42, so that two friction members 43 being installed on floating shelf 42 are separated (as shown in Figure 9) with latch 5, now
Latch 5 can be extracted normally.This structure only installs one or more elastic components 6, the small volume of elastic component 6, quality in base 1
Gently, it is easily installed in base 1.
Wherein, elastic component 6 can be the structures such as spring or shell fragment, be not specifically limited herein.But, because spring is normal
Elastic component and larger elastic force can be produced, therefore preferably elastic component 6 is spring.
In the embodiment shown in Figure 2, Anti-disconnecting socket can be holes socket, or Three-hole socket, can also be
Five spring hole scokets, are not specifically limited herein.But, because not only pluggable three-terminal polarized plus plug but also pluggable the two poles of the earth were inserted on five spring hole scokets
Head, range of application is wider, therefore five spring hole scokets are conventional socket of the prior art.Thus, describe for convenience, hereafter only with
Illustrated as a example by five spring hole scokets.
Specifically, the cover plate 2 of five spring hole scokets is provided with extremely inserts the slotting jack in five holes that the slotting jack of jack and the two poles of the earth is constituted by three,
Sleeve 3 in socket includes extremely inserting the corresponding three pole sleeve of jack and the two poles of the earth sleeve corresponding with the slotting jack in the two poles of the earth, three poles with three
The composition and arrangement orientation of sleeve and the two poles of the earth sleeve can be as shown in figure 3, i.e., three pole sleeves include E poles sleeve 31, three pole N
The pole L poles sleeve 33 of pole sleeve 32 and three, the two poles of the earth sleeve includes being arranged at the He of the two poles of the earth N poles sleeve 34 of the opposite sides of E poles sleeve 31
The two poles of the earth L poles sleeve 35, and the distance of the pole N poles sleeve 32 of the two poles of the earth N poles sleeve 34 to three is less than the pole N poles of the two poles of the earth L poles sleeve 35 to three
The distance of sleeve 32.
