Current extended line merely provides extension function, and in protection, does perfect not, often there will be the situation that line comes off.After situation about coming off online occurs, there is the situation of unexpected power-off can to line machine below, like this, can the machine of grievous injury, machine likely can be caused directly to scrap, the machine of special electronics field.In order to avoid there is this unexpected accident, need a kind of connection very firmly device.
Summary of the invention
The utility model, for deficiency of the prior art, provides a kind of locking socket, and structure is simple, and cost is low, well solves current extended line wire and connects firm not, so that there will be the problem of potential safety hazard when using.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: a kind of locking socket, comprise protective cover, lower house, upper shell, button, contact and fuse, described contact comprises static contact and movable contact spring, described movable contact spring is provided with screens portion and catch, described contact is provided with fixed part, described static contact is provided with clamping section, described button is provided with jacking block, described jacking block is provided with jut, described lower house is provided with first through hole and groove, described upper shell is provided with second through hole, described fuse is provided with some support portions.
Described upper shell is installed on above described lower house, between described upper shell and described lower house, fuse is installed, between described fuse and described upper shell and between described fuse and described lower house, described contact is all installed, described contact is provided with described button, the catch close contact on the jacking block on described button and described movable contact spring.
Described movable contact spring is provided with arc-shaped curvature portion, be arranged at the described jut of the described button between described fuse and described lower house and the inwall close contact of described lower house, be arranged at the described jut of the described button between described fuse and described upper shell and the inwall close contact of described upper shell.
The quantity of described contact is two panels, and the quantity of described button is four, and described lower house is provided with two first through holes, and described upper shell is provided with two second through holes.
The utility model structure is simple, cost is low, well solves current extended line wire and connects not firmly problem, plug can be made to be connected with this device in use fastening, plug can not be pulled out easily, can eliminate the potential safety hazard much caused because plug is not plugged.

Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail: as shown in Figures 1 to 9, a kind of locking socket, comprise protective cover 1, lower house 2, upper shell 4, button 5, contact 3 and fuse 6, described contact 3 comprises static contact 32 and movable contact spring 31, described movable contact spring 31 is provided with screens portion 311 and catch 312, described contact 3 is provided with fixed part 33, described static contact 32 is provided with clamping section 321, described button 5 is provided with jacking block 51, described jacking block 51 is provided with jut 52, described lower house 2 is provided with first through hole 21 and groove 22, described upper shell 4 is provided with second through hole 41, described fuse 6 is provided with some support portions 61.
Described upper shell 4 is installed on above described lower house 2, between described upper shell 4 and described lower house 2, fuse 6 is installed, between described fuse 6 and described upper shell 4 and between described fuse 6 and described lower house 2, described contact 3 is all installed, described contact 3 is provided with described button 5, the jacking block 51 on described button 5 and catch 312 close contact on described movable contact spring 31.
Described movable contact spring 31 is provided with arc-shaped curvature portion 313, be arranged at the described jut 52 of the described button 5 between described fuse 6 and described lower house 2 and the inwall close contact of described lower house 2, be arranged at the described jut 52 of the described button 5 between described fuse 6 and described upper shell 4 and the inwall close contact of described upper shell 4.
The quantity of described contact 3 is two panels, and the quantity of described button 5 is four, and described lower house 2 is provided with two first through holes 21, and described upper shell 4 is provided with two second through holes 41.
Before using this device, need the live wire of inlet wire and zero line to be connected with the contact 3 be arranged between fuse 6 and upper shell 4 and the contact 3 be arranged between fuse 6 and lower house 2 respectively.Be installed on by wire on fixed part 33, then, the curved portions that fixed part 33 both sides tilt compressed downwards, like this, wire is just connected with contact and fastens.
The metal insert 7 of some plugs in the market has two holes, front hole 71 and metapore 72.Metapore 72 is all arranged in the housing of plug, for connection metal line.When plug inserts this device time, contact with contact 3.Static contact 32 is provided with clamping section 321, clamping section 321, the sheet metal that mainly one end is bending, it is by the design feature of self, tightly can press against static contact 32.When the metal insert 7 on plug inserts, clamping section 321 can by the metal insert 7 on plug tightly press to static contact 32.Then the metal insert 7 on plug continues to insert, and due to movable contact spring 31 being provided with screens portion 311, the structure in screens portion 311 is metal protuberances, and it can be stuck in the front hole 71 of the metal insert 7 on plug.Like this, the metal insert 7 on plug just can not have been extracted.Movable contact spring 31 is also provided with arc-shaped curvature portion 313, because the self structure of arc-shaped curvature portion 313 affects, its can by screens portion 311 tightly press to metal insert 7, in the front hole 71 on the metal insert 7 making screens portion 311 can very firmly be stuck on plug.Such setting, after the metal insert 7 on plug inserts this device, is just difficult to be pulled out.This makes it possible to the situation of preventing some surprisingly to extract.
When needs pull the plug out of the socket time, only need to press the button 5 and just can realize.Button 5 is provided with jacking block 51, jacking block 51 and catch 312 close contact on movable contact spring 31.After button 5 is pressed, jacking block 51 just promotes catch 312, and make movable contact spring 31 away from metal insert 7, like this, the front hole 71 on metal insert 7 will be left by screens portion 311.Like this, plug just can have been pulled out smoothly.
The utility model structure is simple, cost is low, well solves current extended line wire and connects not firmly problem, plug can be made to be connected with this device in use fastening, plug can not be pulled out easily, can eliminate the potential safety hazard much caused because plug is not plugged.
