Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail: as shown in Figures 1 to 7, a kind of locking extended line, comprise upper cover 1, lower cover 2, contact 3, button 4, touch switch 5 and spring 6, described upper cover 1 is arranged at above described lower cover 2, described upper cover 1 is provided with button hole 11, lower switch groove 22 is provided with in described lower cover 2, lower contact groove 23 and inserting slot 24, correspondingly with described lower cover 2 in described upper cover 1 be provided with upper switch groove, upper contact groove and upper wire casing, described contact 3 comprises movable contact spring 31 and static contact 32, described movable contact spring 31 is provided with screens portion 311 and catch 312, described button 4 bottom is provided with initiative part 41, described touch switch 5 is provided with operand 51.
Described contact 3 is arranged in described lower contact groove 23, described button 4, described touch switch 5 and described spring 6 is provided with in described lower switch groove 22, described spring 6 is arranged at below described button 4, described initiative part 41 is connected with described touch switch 5, and described operand 51 is connected with described catch 312.
Described upper cover 1 leading section is provided with line outlet 12, and described upper cover 1 rearward end is provided with lower incoming line, and described lower cover 2 leading section is provided with lower line outlet 21, and described lower cover 2 rearward end is provided with lower incoming line 25.
Described contact 3 is provided with fixed part 33, described static contact 32 is provided with clamping section 321, described movable contact spring 31 is provided with arc-shaped curvature portion 313.
Described initiative part 41 is provided with inclined-plane 42.
This device generally comprises the secondary contact 3 of two secondary contacts 3, and is connected with the live wire of inlet wire 8, and another pair is connected with the zero line of inlet wire 8.Contact 3 is provided with fixed part 33, this makes it possible to wire to place therewith, then compressed mutually by the two panels sheet metal of fixed part 33, like this, wire has just been connected firmly with contact, will wire be made easily to be separated with contact.After contact 3 is connected with inlet wire 8, be installed in lower contact groove 23, then line cover 7 is positioned on lower incoming line 25.Then spring 6 is positioned in lower switch groove 22, then button is installed on spring 6, then touch switch 5 is also installed in lower switch groove 22.Practical two touch switchs 5 of this device, corresponding with contact 3.During installation, operand 51 and catch 312 close contact on movable contact spring 31 of touch switch 5.Finally, covered by upper cover 1, after tighten the screws, this device has just installed.
During use, plug 9 is inserted from lower line outlet 21, realizes being connected to, namely achieve the function of outlet extension cords.Porose due to the sheet metal on general plug 9 being arranged, like this, when plug 9 has just inserted lower line outlet 21, 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 plug 9 inserts, clamping section 321 can by plug 9 tightly press to static contact 32.Then plug 9 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 hole of plug 9.Like this, plug 9 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 plug, in the hole that screens portion 311 can be very firmly stuck on plug 9.Such setting, after plug 9 inserts this device, is just difficult to be pulled out.This makes it possible to the situation of preventing some surprisingly to extract.
Only need to press the button 4 just can like a cork plug 9 have been extracted.Because initiative part 41 is provided with inclined-plane 42, like this, the structure of initiative part 41 is exactly lower little greatly upper.When successful installation, due to the effect of spring 6, by button 4 jack-up, like this, what initiative part 41 contacted with touch switch 5 is exactly bottom.When button 4 is pressed time, the top of initiative part 41 is just depressed, and contacts with touch switch 5.Because initiative part 41 is lower little large structures.When replacement bottom, top contacts with touch switch 5, just give touch switch 5 one thrusts, touch switch 5 is pushed away initiative part 41.And the operand 51 that touch switch 5 is arranged and catch 312 close contact, like this, catch 312 will receive the thrust of operand 51.Then, catch 312 can be pushed away from static contact 32, and namely movable contact spring 31 is away from static contact 32.Such setting, the screens portion 311 of restriction plug 9 movement, can leave in the hole on plug 9, last plug 9 just can be pulled out.
The utility model structure is simple, and cost is low, can extending wire very easily, and well solves and add plug-and-socket in addition, so that increases the problem of potential safety hazard.
