Description: [0001] The invention relates to a plug fuse for a plug of an electric cable, the contact pins of which can be plugged into form-contacting contact openings of a socket, in particular of a wall socket.
Sockets and especially stationary wall sockets are popular for small children study objects and are therefore secured against unipolar mating. In addition, unused sockets can be closed with a fuse, for example a plastic cap.
But also known are fuses for plugs of electrical cables that are plugged into a wall socket. For example, US Pat. No. 4,045,108 proposes a spring element for securing plugs into wall sockets, which is arranged on the front panel of the socket. Two spaced-apart spring arms comprise the plug and in the gap between them, the electric cable is guided. The spring element is fastened by means of a screw on the front panel. This screw also secures in a known manner the front panel on the housing of the socket. A similar solution is disclosed in US 2 659 059.
In US 6,071,142 A discloses a two-arm connector fuse, which can be arranged by means of suction cups, which are arranged at the end of the arms, on the front panel or a surrounding wall. The arms are connected to each other by a hinged joint, whereby electrical cable is accommodated in the joint at the same time.
In a further solution of this type according to US 2004/0166 718 A1 has a screwed onto the front panel fuse element, an almost vertically projecting from the front panel arm with a U-shaped clamp for the cable. The clamp is attached to the end of the arm away from the front panel.
In a cable fuse according to US 2011/0237 114 A1, the cable must be passed under a two-armed fuse element and around the plug. Pulling out the plug can not be prevented just here.
Are also known wire-shaped securing bracket, which are also fastened by means of a screw on the front panel. The securing bracket is shaped so that it covers the connector at least at an angle of 180 °.
The prior art has in common that only a maximum of two plugs are secured in a socket can be arranged and that the fuse can be leveraged with sometimes little effort.
The invention is therefore based on the object to develop a plug fuse for a plug of an electric cable, which avoids the disadvantages of the prior art, is easy to manufacture and which is particularly applicable as a child safety device.
The object is solved with the features of patent claim 1.
An inventive connector fuse for a plug of an electric cable, the pins are in form-responsive contact openings of a socket, in particular a wall socket can be inserted, can be arranged on the socket and has at least one fuse element for detecting the electric cable. The plug fuse comprises an adapter with at least one, on the adapter movable and releasably secured securing hook as a security element.
The plug fuse is preferably and advantageously applicable to multiple sockets, preferably three, have around a center around arranged connector slots.
Preferred and advantageous embodiments of the plug fuse are disclosed in the dependent claims.
The adapter of the plug fuse advantageously has a hollow base body, one end face of which is open and the opposite end face is provided with a bottom. At least one sleeve for the arrangement of the securing hook is formed on the outer wall of the main body.
On the outer wall of the main body of the adapter preferably three equally spaced sleeves are integrally formed, each sleeve is a safety hook can be assigned.
The at least one safety hook is V-shaped, with two mutually arranged legs whose ends are designed as against each other directed, semicircular arcs. The connecting region of the legs is circular.
The safety hook is at the same time movably connected to the sleeve of the adapter in the connection region, for example screwed.
The invention will be described below in an embodiment with reference to a drawing. In the drawing show the
1 shows an adapter of a connector fuse according to the invention;
Fig. 2: seen the adapter of Figure 1 from above.
Fig. 3: seen the adapter of Figure 1 from below.
4 shows a mounted adapter according to FIG. 1;
5: a safety hook according to the invention and FIG. 6: the plug safety according to the invention in function.
A conventional wall socket 10 has on a front panel 13 up to three slots 11 for connector 14 (Fig. 1,6).
An inventive connector fuse comprises an adapter 1 with, in the embodiment three, the adapter 1 movable and releasably fastened securing hooks 8 as a fuse element of an electric cable 15 of the plug 14. D. h. Three plugs can be secured simultaneously and independently of each other.
The adapter 1 has a hollow body 2 (accessibility and low mass), one end face with an opening 5 and the opposite end face is provided with a bottom 7 (Fig. 1.3). By means of a bore 6 in the bottom 7 of the adapter 1 via the locking screw 12 of the front panel 13 on the front panel 13 can be fixed.
On the outer wall of the base body 2 are correspondingly three equally spaced sleeves 3 for the arrangement of a respective safety hook 8 formed (Fig. 2). The distance of the sleeves 3 from each other is about 120 ° corresponding to the arrangement of the three slots for connector 14th
Each safety hook 8 is V-shaped, with two mutually arranged legs whose ends are designed as against each other, semicircular arcs. The connecting region of the legs is circular (FIGS. 5, 6).
The securing hook 8 is at the same time movably screwed in the connection area in a bore 4 of the sleeve 3 of the adapter 1 (Fig. 6), wherein in the connection area additionally a guide nut 9, as well as the screw in the embodiment with thread M3, can be arranged , for example soldered.
The handling of the plug fuse is done in such a way that first the relevant wall socket 10 is disconnected from the network and subsequently loosened and removed the locking screw of the front plate. Subsequently, the locking screw is guided through the opening 5 to the bore 6 and the adapter 1 is bolted to the front panel 13. The safety hooks 8 can be bolted to the sleeves 3 or stored separately.
Subsequently, a safety hook 8 is isolated and the arcuate ends of the legs are so far away from each other that they can be performed behind the plug 14 via the electric cable 15 and the ends of the electric cable 15 engage around 180 °. Subsequently, a screw is guided by the guide nut 9 and screwed into the bore 4 of the sleeve 3. The plug 14 can now no longer be pulled out of small children from the socket.
