Description
Technical field
The utility model relates to a kind of three-electrode power plug inner frame, refer to a kind of plug internal frame especially with grounding elastic part with grounding elastic part.
Background technology
General daily life and the electrical equipment of industrial operation or the use of appliances, the power source of its alternating current mainly is to engage with socket by a wire and plug, and conducts current to electrical equipment or appliances.The operating type of general plug injection molding is after the line ball operation is finished, and terminal is inserted an internal frame body, it is inserted in the mould of plug body again, carries out one injection molding (molding).
Again, a kind of three-electrode power plug is arranged in the plug, the plug of this kind kenel, because more aforementioned general plug tool fail safe in the use, using so extensively be used in general electrical equipment, also is the safety requirements of some advanced country, also is widely used in the specification of European all states.
And so-called three-electrode power plug, background technology 1 for example shown in Figure 1, as German DE3911315A1 patent case, with a plug at its exterior contour as yet not before the injection molding, be provided with an internal frame (1), respectively be provided with a positive terminal (12) and negative terminal (because section relation on the support body (11) of described internal frame (1), the graphic wherein positive terminal that only shows), and be provided with a grounding elastic part (14), wear a ground wire hole (141) on the described grounding elastic part (14), plug after will being shaped in use inserts outside socket, and be convexly equipped with the earth terminal of line hole (141) accordingly on the external receptacle, in the ground wire hole (141) of the grounding elastic part (14) of insertion plug, the two forms joint, and can reach the safe effect of ground connection.Again, this kind grounding elastic part (14) is suitably to bend shaping, and make up by build-in with the end and the support body (11) of described grounding elastic part (14) since described grounding elastic part (14) one sidepieces extend outward a hollow upright tubular put line tube (142).The described line tube (142) of putting is in order to accept the usefulness of ground wire stamen wire harness, though and since ground wire stamen wire harness by plural stamen wire harness collection, but, often there is the so-called copper phenomenon of revealing (to have part stamen line can't fall into the described line tube (142) of putting smoothly when therefore putting line because described constriction is not quite tight.So described background technology 1, a L shaped lug (15) of general one-tenth is set on support body (11), and described lug (15) is provided with a correspondence and puts the taper hole (151) of line tube (142) (or claiming horn mouth), the kenel of described taper hole (151) by restraining gradually outside to inside can provide the guiding of ground connection stamen line.Yet the problem of described background technology 1 is that it must be provided with a L shaped lug (15) at support body (11) in addition in addition, but, supports described L shaped lug (15) because only forming at a side, be easy to generate the stress concentration phenomenon, and under the situation of undercapacity, rupture easily and cause the serious flaw of quality.And then form unsettled on an other end limit and do not have a support, therefore cause distortion easily, make described taper hole (151) be not easy to aim at the described line tube (142) (promptly producing dislocation) of putting, influence is put line accurately and quality.
And see by Fig. 2, described lug (22) bottom is provided with a groove (221), can allow that putting line tube (24) includes in, but because the usually described cross section of putting line tube (24) for circular (with graphic laterally be cross section), and the cross section of described groove (221) also is circular, and after putting that line finishes, the described line tube (24) of putting must be clamped by the operation of riveting line, and this moment, circle was out of shape because clamp, make the circular groove of described lug (22) be difficult to hold, be that the described clamping deformation state of putting line tube (24) can be interfered circular groove (221), cause the damage of described lug (22).So still there is its problem to exist.
Summary of the invention
The objective of the invention is to, a kind of three-electrode power plug inner frame with grounding elastic part is provided, in order to overcome above-mentioned defective.
And the utility model solves the employed technological means of previous problem, mainly be to design a kind of three-electrode power plug inner frame with grounding elastic part, this kind plug be meant its exterior contour as yet not injection molding before, be provided with an internal frame, just respectively be provided with one on the support body of described internal frame, negative terminal, and be provided with a grounding elastic part, wear a ground wire hole on the described grounding elastic part, plug after will being shaped in use inserts outside socket, and be convexly equipped with the earth terminal in line hole accordingly on the external receptacle, in the ground wire hole of the grounding elastic part of insertion plug, the two forms joint, and can reach the safe effect of ground connection.Described internal frame comprises a support body, just respectively be provided with one on the described support body, negative terminal, and be provided with a grounding elastic part, wear a ground wire hole on the described grounding elastic part, and described grounding elastic part is bent shaping, and make up by build-in with the end and the support body of described grounding elastic part, what described grounding elastic part one sidepiece extended outward a hollow upright tubular puts the line tube, it is characterized in that described support body extends a skeleton frame, and described skeleton frame is provided with a hollow hole seat, edge forms one and restrains shape from outside to inside gradually within the described hollow hole seat, and the hollow of described hollow hole seat with put the line tube and communicate.
The beneficial effects of the utility model are compared with the prior art, and by the solid design of skeleton frame, rigidity and the intensity than background technology also is increase relatively.And the solid design by skeleton frame also promotes and inserts the stability of stamen line, reduces the deviation of dislocation, promotes the quality of product;
Secondly, described skeleton frame is corresponding mutually by two vertical pieces, and the bottom of two vertical pieces connects one and be provided with the bottom sheet of perforation, and to establish a hollow cylinder post between described two vertical pieces be the hollow hole seat, with the reinforcement fin of described two vertical pieces, increase intensity of the present utility model as side;
At last, the bottom of described bottom sheet of the present utility model is provided with a groove, can hold described top of putting the line tube, and make described top of putting the line tube can be used as the stable of described skeleton frame and support, and the groove cross section of described bottom sheet of the present utility model is one to be selected from ellipse, rectangle or thin-and-long, and described top of putting the line tube is a circle.Mainly because after putting line, the top that must will put the line tube clamps (being the riveting line), and in distortion that clamped condition produced, must have one in response to, therefore the groove cross section by described bottom sheet is one to be selected from one of ellipse, rectangle or thin-and-long, the spatial accommodation of allowing described distortion can be arranged, and be unlikely to push the periphery of described groove, prevent to destroy and be out of shape.
