Abstract
The utility model discloses a safety plug socket with a locking device, comprising a plug and a socket. The safety plug socket with a locking device is characterized in that the locking device is arranged between the plug and the socket. The locking device can be a screw sleeve, or a clamped sleeve, or a flexible lock catch, or a door catcher locking device, and the plug and the socket can be conveniently locked together after the plug is plugged into the socket. The plug can be effectively prevented from being pulled out due to the pulling of a power cord when an electric appliance is operated, and accordingly, the power off the electric appliance can be avoided. The safety plug socket with a locking device is an ideal substitute of traditional plug socket.
Description
The utility model relates to a kind of electric mortiser headstock, particularly a kind of Electric safety plug seat that has locking device.
Traditional electric mortiser headstock, the fit form of its plug and socket is plug conductors and directly inserts jack, does not have other locking device between plug and the socket again, only depends on the conductive reed in the jack that the chucking power of plug conductors is kept being connected between plug and the socket.Because contact engaging and separating force very little (contact engaging and separating force can make the plug difficulty between plug conductors and the jack too greatly again), so the connection reliability of this traditional electric mortiser headstock is poor, often owing to controlling electric device particularly affects power line to cause plug to deviate to cut off the power supply from socket during the portable electrical equipment such as hair dryer, electric iron, dust catcher.
At the above-mentioned deficiency of traditional electrical connector assembly, the utility model provides a kind of Electric safety plug seat that has locking device just, and it can make after plug conductors is inserted in the jack between plug and the socket and keep firm being connected by locking device.
The purpose of this utility model realizes by following measure: the utility model is made up of plug and socket etc., it is characterized in that: a locking device is arranged between the plug and socket.
Locking device is the screw shell that two ends all have internal thread, the double-screw bolt that one projection is arranged on the socket, jack are positioned at the top of double-screw bolt, and header body is cylindrical, be processed with external screw thread on it, the internal thread at screw shell two ends respectively with socket and plug on external screw thread match.
Locking device can also have the screw shell that the external screw thread other end has internal thread for one one end, one tapped blind hole is arranged on the socket, external screw thread on its internal thread and the screw shell matches, jack is positioned at the bottom of tapped blind hole, header body is cylindrical, be processed with external screw thread on it, match with internal thread on the screw shell.
Locking device can also have the screw shell of internal thread for one one end, and the double-screw bolt of a projection is arranged on the socket, and the internal thread on its external screw thread and the screw shell matches, and jack is positioned at the top of double-screw bolt, and the other end of screw shell axially cover is stuck on the header body.
Locking device can also have the clamping sleeve of folding shape draw-in groove for one one end, the cylinder that one projection is arranged on the socket, this cylinder be provided with the clamping sleeve on all corresponding bayonet lock of draw-in groove quantity and position, jack is positioned at cylindrical top, and the other end of clamping sleeve axially cover is stuck on the header body.
Locking device can also be a flexible snap close, and an end of this flexibility snap close is fixed on the socket, and the other end has a button pin, and one and the corresponding button pin-and-hole of button pin are arranged on the header body.
Locking device can also be that a ball catch is decided device, has one to bump the pearl groove on the socket, has one correspondingly with it to bump pearl on the header body.
Accompanying drawing has provided three embodiment of the present utility model.
The drawing of accompanying drawing is described as follows:
The decomposing schematic representation of Fig. 1: embodiment 1.
The decomposing schematic representation of Fig. 2: embodiment 2.
The decomposing schematic representation of Fig. 3: embodiment 3.
Below in conjunction with accompanying drawing the utility model is described in further detail.
As Fig. 1, one tapped blind hole is arranged on the socket of present embodiment, jack is positioned at the bottom of tapped blind hole, header body is cylindrical, be processed with external screw thread on it, an end of screw shell is an external screw thread, matches with the internal thread of tapped blind hole on the socket, the other end of screw shell is an internal thread, matches with external screw thread on the header body.Generally speaking, screw shell is spun on the header body.With in the jack on the insertion of the plug conductors on the plug socket, with in the tapped blind hole on the screw shell precession socket, screw shell just locks together plug and socket firmly then during use.As Fig. 2, the locking device of present embodiment is the clamping sleeves that one one end has two folding shape draw-in grooves, and the cylinder of a projection is arranged on the socket, this cylinder be provided with two with the clamping sleeve on the corresponding bayonet lock in draw-in groove position, jack is positioned at cylindrical top.Generally speaking, the other end of clamping sleeve axially overlaps and is stuck on the header body.During use, plug conductors is inserted jack, then the bayonet lock on the cylindrical projection on the draw-in groove alignment socket of clamping sleeve is pushed, a rotation slightly again after putting in place, bayonet lock promptly is snapped in the draw-in groove, and like this, the clamping sleeve is about to plug and socket locks together firmly.As Fig. 3, in the present embodiment, locking device is a flexible snap close, and an end of this flexibility snap close is fixed on the socket, and the other end has a button pin, and one and the corresponding button pin-and-hole of button pin are arranged on the header body.During use, can flexible snap close is cocked, then plug is inserted jack, will detain again in the button pin-and-hole on the pin insertion header body, flexible snap close is about to plug and socket and locks together firmly.
If socket adopts thread protrusion or tapped blind hole or has the form of the raised cylinder of bayonet lock; can also dispose a screw thread protecting cover easily in addition or have the protecting cover of draw-in groove; when not electricity consumption, protecting cover can be spun on or holding on socket to hide jack; can play the safeguard protection effect, contact power supply and electric shock accidents takes place to prevent child and feeblemindedness person.
Compare with traditional electric mortiser headstock, plug was connected with the reliable of socket when this safety plug socket with locking device that the utility model provides can guarantee electricity consumption effectively, simultaneously tool is with characteristics simple in structure, easy to use, be a kind of desirable regeneration product of traditional electrical connector assembly, have higher application value.
