Description
Technical field
The utility model relates to a kind of power supply connecting device, particularly a kind of socket and plug construction.
Background technology
Socket, as a kind of daily living article, is widely used in life, so its fail safe enjoys people's concern.Current socket with mostly be direct plugging-in coordinating of plug and coordinate, and can successfully insert in socket for the ease of plug, conventionally jack is larger than pin, and the manufacturer of socket and plug is often different, as plug producer mostly is the product man of living electric apparatus, and the manufacturer of socket mostly is the producer of special production socket, the mated condition of therefore a lot of jacks and pin is very undesirable, often there is the situation of loose contact, so easy generation is because being used the overheated phenomenon that causes burning distortion, also likely there is electric leakage or on fire, there is very large potential safety hazard, but also be easy to produce the phenomenon that gets loose, cause thorough power-off.
In addition, two or three utmost point sockets of direct plugging-in are due to higher to space requirement at present, and producer, in order to save space, often can only be located at three utmost point jacks both ends of socket, and two utmost point jacks is located to the middle part of socket.
Summary of the invention
The technical problems to be solved in the utility model, is to provide a kind of socket and plug construction, and use is threaded, and contact is good, connects reliable.
The utility model is achieved in that a kind of screw thread socket and plug construction, described socket comprises sealed upper shell and lower house, in described lower house, horizontal arrangement has a L utmost point sheet metal and a N utmost point sheet metal side by side, and on described L utmost point sheet metal and N utmost point sheet metal, correspondence is stood to being fixedly connected with a plurality of internal thread link slots; Described plug comprises L utmost point pin and N utmost point pin, described L utmost point pin and N utmost point pin are connected respectively a grip part, described L utmost point pin and N utmost point pin are external screw thread joint pin, the external screw thread of described L utmost point pin and N utmost point pin respectively with described L utmost point sheet metal and N utmost point sheet metal on internal thread match.
Further, be also provided with E utmost point sheet metal in described lower house, described E utmost point sheet metal and L utmost point sheet metal, N utmost point sheet metal be horizontal arrangement side by side, and on this E utmost point sheet metal, correspondence is stood to being fixedly connected with a plurality of internal thread link slots; Described plug comprises E utmost point pin, and described E utmost point pin is external screw thread joint pin, and the internal thread on the external screw thread of described E utmost point pin and described E utmost point sheet metal matches.
Further, the groove bottom of internal thread link slot is recessed hemispherical, and the end of described external screw thread joint pin is match protruding hemispherical.
The utility model has the advantage of: the utility model socket adopts internal and external threads to be connected with plug, and contact area is larger, and is not easy to become flexible, and therefore contact is good, connects reliable.And after adopting internal and external threads to connect, lower to space requirement, three utmost point jacks in two or three utmost point sockets and two utmost point jack positions in socket are no longer restricted, and can arrange arbitrarily.
Accompanying drawing explanation
The utility model is further described with reference to the accompanying drawings in conjunction with the embodiments.
Fig. 1 is the structural representation of the utility model socket and plug one embodiment.
Fig. 2 is the structural representation of the utility model socket and another embodiment of plug.
Fig. 3 is the two bottom surface structure schematic diagram of internal thread link slot in the utility model socket and the pin on plug.
Embodiment
Refer to shown in Fig. 1, one embodiment of screw thread socket of the present utility model and plug construction, this embodiment is the two poles of the earth (i.e. two holes) socket 1 and plugs 2, described socket 1 comprises sealed upper shell 11 and lower house 12, in described lower house 12, horizontal arrangement has a L utmost point sheet metal 13 and a N utmost point sheet metal 14 side by side, on described L utmost point sheet metal 13 and N utmost point sheet metal 14, correspondence is stood to being fixedly connected with a plurality of internal thread link slots 16, is respectively L utmost point internal thread link slot 163 and N utmost point internal thread link slot 164; Described plug 2 comprises L utmost point pin 23 and N utmost point pin 24, described L utmost point pin 23 and N utmost point pin 24 are connected respectively a grip part 22, described L utmost point pin 23 and N utmost point pin 24 are external screw thread joint pin, the external screw thread of described L utmost point pin 23 and N utmost point pin 24 respectively with described L utmost point sheet metal 13 and N utmost point sheet metal 14 on internal thread match, be that the external screw thread of L utmost point pin 23 and the internal thread of L utmost point internal thread link slot 163 match, the internal thread of the external screw thread of N utmost point pin 24 and N utmost point internal thread link slot 164 matches.
Refer to shown in Fig. 2, another embodiment of screw thread socket of the present utility model and plug construction, this embodiment is three utmost points (i.e. three holes) socket 1 and plugs 2, in described lower house 12, be also provided with E utmost point sheet metal 15, described E utmost point sheet metal 15 and L utmost point sheet metal 13, N utmost point sheet metal 14 be horizontal arrangement side by side, on this E utmost point sheet metal, 15 correspondences are stood to being fixedly connected with a plurality of internal thread link slots 16, are E utmost point internal thread link slot 165.Described plug also comprises E utmost point pin 25, described E utmost point pin 25 is external screw thread joint pin, internal thread on the external screw thread of described E utmost point pin 25 and described E utmost point sheet metal 25 matches, and the internal thread of the external screw thread of described E utmost point pin 25 and described E utmost point internal thread link slot 165 matches.
Certainly in a further embodiment, also three utmost points and the two poles of the earth can be combined in a socket 1, become multiplex socket.
Again as shown in Figure 3, in above-mentioned enforcement, in order further to increase the contact area of socket 1 and plug 2 and to contact reliably, groove bottom that can internal thread link slot 16 is set to recessed hemispherical, and what the end of described external screw thread joint pin was set to match is protruding hemispherical.
Operating process of the present utility model: because socket 1 and being connected to of plug 2 are threaded, while therefore connecting, need be by the external screw thread joint pin precession socket 1 on plug 2, cause like this connecting line 3 on external screw thread joint pin to produce certain torsion and affect the stability that socket 1 is connected with plug 2, therefore before plug 2 inserts socket 1, preferably connecting line 3 can be done to rightabout pre-rotation, as: first the connection of plug 2 is rotated counterclockwise to some circles, and then press clockwise direction by the external screw thread joint pin precession socket 1 on plug 2, can eliminate the torsion of connecting line 3 like this.
In sum, the utility model socket adopts internal and external threads to be connected with plug, and contact area is larger, and is not easy to become flexible, and therefore contact is good, connects reliable.And after adopting internal and external threads to connect, lower to space requirement, three utmost point jacks in two or three utmost point sockets and two utmost point jack positions in socket are no longer restricted, and can arrange arbitrarily.
Although more than described embodiment of the present utility model; but being familiar with those skilled in the art is to be understood that; our described specific embodiment is illustrative; rather than for the restriction to scope of the present utility model; those of ordinary skill in the art are in equivalent modification and the variation done according to spirit of the present utility model, all should be encompassed in the scope that claim of the present utility model protects.
