Abstract

The utility model discloses a novel plug sleeve for switch socket. The utility model comprises a sleeve body and inserting pieces symmetrically arranged along two sides of the sleeve, wherein upper parts of the two inserting pieces are inclined inward, forming a jack for tightly clamping pins, outer side walls of the inserting pieces are provided with convex edges; the horizontal projection of the convex edges is beyond the range of the horizontal projection of the inserting pieces. Because the two sides of the inserting pieces of the plug sleeve are provided with the heaves, terminals of the plug sleeve are inserted in holes of a base corresponding to the terminals; a face plate and the base are buckled on; a stiffening plate on the face plate, which is originally used to prevent the plug sleeve from oscillating left and right, has the tail end pressed on the two heaves, which results in fixing the plug sleeve and preventing the vertical movement of the plug sleeve when pins of the plug are pulled out, thereby ensuring that the contacts between bolts and terminals are good and the bolts do not fall off after the long-term use; moreover, the plug sleeve applying the structure does not add the assembling procedure of the plug and does not need to add any part, thereby the utility model reaches the better use effect without expending more on raw materials.

Description

A kind of sleeve that is used for combined socket and switch

Technical field

The utility model relates to a kind of electrician's hardware, particularly a kind of sleeve that is used for attachment plug pin on two utmost points or three pole sockets.

Background technology

Present mains switch socket generally includes a base, two or three copper sleeves, sleeve top is provided with the socket that is used to clamp pin on the plug, the bottom is provided with the terminal that connects power line, and sleeve directly is placed in aperture corresponding on the base, covers panel and gets final product.The socket that has at present position corresponding with sleeve on panel is provided with gusset, prevents that sleeve from swinging, but sleeve only relies on screw to hold out against terminal from the side and locatees in the direction perpendicular to panel.During wiring, on screw, lock-screw, head of screw just compress power line with the power line solderless wrapped connection, and the tip of screw overhead when the plug pin of plug inserts sleeve, gets final product energized in the terminal side.When pulling the plug out of the socket pin, because socket has clamping action to plug pin, so sleeve is subjected to the power of outwards pulling out simultaneously, screw and terminal side constantly are subjected to frictional force repeatedly.After long-term the use, just can get loose between screw and the terminal, thereby cause loose contact.

The utility model content

The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of novel sleeve that can be fixed easily on the combined socket and switch of being used for is provided, and ensures well contact under the long-term operating position of combined socket and switch.

The utility model is achieved by following technical proposals: a kind of novel sleeve that is used for combined socket and switch, comprise body and the inserted sheet that is provided with along the body bilateral symmetry, the upper end of two inserted sheets slopes inwardly and is formed for clamping the socket of plug pin, it is characterized in that: the lateral wall of described inserted sheet is respectively equipped with flange, and the projection of described flange on horizontal plane exceeds the scope of the floor projection of inserted sheet.

Described flange and inserted sheet integrated punching form.

The upper surface of described flange is the plane.

The groove that described inserted sheet is provided with from the position of flange and extends to the socket direction.

The sheet that described body bottom is provided with by punching press partly bends the terminal that forms.

Compared with prior art, the beneficial effects of the utility model are: because the inserted sheet both sides of sleeve have projection, after the terminal of sleeve being put on the base corresponding hole, panel and base are buckled, and the end of the gusset that was used to originally on the panel to prevent that sleeve from swinging can be pressed in this two projections, is used for fixing sleeve, when the pin that prevents plug is extracted, sleeve vertically moves, thereby has ensured that screw contacts with the good of terminal place, can not get loose under long-term situation about using.And the sleeve of this structure, do not need to increase the assembling procedure of socket, do not need to increase spare and accessory parts yet, can not spend more materials simultaneously yet and just reach result of use preferably.

Embodiment

As shown in Figure 1, the utility model is used for the novel sleeve of combined socket and switch, it comprises body 12, be located at two symmetrical inserted sheets 1 of body 12 both sides, the upper end of two inserted sheets 1 slopes inwardly and is formed for clamping the socket 2 of pin on the plug, in the bottom of U-shaped sleeve one punching press mouth 3 is arranged, the sheet that punching press is come out partly is bent to form terminal 4.The lateral wall of inserted sheet 1 is respectively equipped with the horizontal flange 5 that is formed by punching press, the projection of flange 5 on horizontal plane exceeds the floor projection scope of inserted sheet 1, this point mainly is that convenient gusset 9 as panel 8 in the accompanying drawing 4 is pressed on the flange 5, and can not be subjected to the interference of inserted sheet 1.In the present embodiment, flange 5 is arranged on the left and right sides face of inserted sheet 1, therefore can directly utilize the material level punch forming of inserted sheet 1.Perhaps, this flange 5 can replace with the projection 13 that is arranged on two inserted sheets, 1 front side as shown in Figure 5, perhaps also can be as shown in Figure 6, front and back two ledges 14 with body 12 replace, but the stressed effect of this two kinds of structures is all not as the structure shown in the accompanying drawing 1, because the sleeve of this structure easy deformation in long-term use.In order to make sleeve stressed better when being pushed down by the gusset 9 of panel 8, though the stress point also on the flange 5 more near socket 2 centers, so on two inserted sheets 1 respectively punching press a groove 10 that extends to socket 2 places from flange 5 is arranged.Because socket 2 is the upper ends by two inserted sheets 1 to slope inwardly and forms, so setting of this groove 10, making gusset 9 on the panel 8 can pass groove 10 withstands on the flange 5, thereby the stress point that acts on the sleeve can be more near socket 2, sleeve is compressed by the gusset on the panel 89 easily, and can not take too many space.

Shown in accompanying drawing 2,3, the terminal 4 of sleeve is inserted in the aperture corresponding on the base 7, and locatees from terminal 4 sides and the while turning circuit by screw 6, and two inserted sheets 1 expose the top at base.As shown in Figure 4, when the buckle 11 of panel by the side fastened with base 7, the gusset 9 on the panel 8 passed flange 5 places that groove 10 on the inserted sheet 1 is pressed in inserted sheet 1 both sides.Such sleeve structure is compact more, and ground wire, zero line, live wire can general this sleeves, and it is simple in structure, and be easy to use, saves and produce and die cost.
