Abstract
The utility model discloses a plug inner frame. The plug inner frame comprises a main body, wherein an insert sheet hole is formed in the main body, the insert sheet hole penetrates through the front end surface and back end surface of the main body, the insert sheet hole is in adaptation with an insert sheet of a plug, and an insert sheet buckle is arranged in the insert sheet hole on the back end surface. The plug inner frame disclosed by the utility model can meet the requirements of enabling a processing technology to be simple, saving materials and ensuring the exposed size of the insert sheet to be in line with safety regulations, and can thoroughly prevent short circuit and water penetration caused by intersection of a neutral wire and a live wire; and furthermore, the plug inner frame is easy to pass testing and certification in countries all over the world.
Description
Technical field
The utility model relates to the electric elements technical field, more precisely, relates to a kind of inner bracket of power plug.
Background technology
Plug construction is to connect power supply and electrical equipment, and guarantee electrical equipment can be safely, a vitals of stable use.In existing attaching plug, inner bracket of power plug is used for the fixed power source contact chip, to such an extent as to and the structure of existing plug internal frame is too simple when intaking in the plug or during aqueous vapor, the water capacity easily circulates between electrode, causes the plug short circuit, brings danger.And the inserting-plate hole stationarity on the existing internal frame is undesirable, cause contact chip to expose size restive, both consuming timely when assembling is produced also require the workman to have higher production qualification.
The utility model content
The deficiency that the utility model purpose exists in order to overcome above-mentioned prior art provides a kind of one side can prevent moisture penetration in plug and circulates between electrode, can guarantee that on the other hand contact chip exposes the plug internal frame of size.
The technical solution of the utility model is: plug internal frame, comprise main body, on the described main body inserting-plate hole is set, described inserting-plate hole runs through front end face and the rear end face of described main body, the inserted sheet of described inserting-plate hole and plug is suitable, is provided with the inserted sheet buckle at the inserting-plate hole of described rear end face.
Outer rim at the front end face inserting-plate hole of described main body is provided with bulge loop.
Rear end face in described main body is provided with groove, and described inserted sheet buckle is arranged in the described groove.
Described inserted sheet buckle comprises a pair of plastic sheet.
The wall of described plastic sheet is provided with salient point, and the wall of described inserted sheet is provided with the circular hole suitable with described salient point.
Described plastic sheet is symmetrical arranged, and described salient point is symmetrical arranged.
The rear end face of described plug internal frame is provided with convex tendon.
The outer rim of described convex tendon is by interior past outer incline.
The alternate setting of described convex tendon and inserting-plate hole.
The utility model compared with prior art, its beneficial effect is:
Be provided with the muscle of three projections between the utility model plug internal frame inserting-plate hole overleaf, can prevent that sealing enters attaching plug after, between electrode the circulation and cause short circuit, thereby avoided dangerous generation.And internal frame jack inside is provided with the buckle of one group of projection, improved the crystallized ability of jack, and what guaranteed contact chip exposes the size conforms industry standard.

Fig. 3 is the rearview of the utility model plug internal frame;
Fig. 4 is the upward view of the utility model plug internal frame.
Embodiment
Below pass through embodiment, and the utility model is described in further detail by reference to the accompanying drawings.
Such as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the utility model provides a kind of and is provided with the contact chip buckle in inserting-plate hole inside, is injected with the plug internal frame of three convex tendons at the plug internal frame rear end face.
Plug internal frame comprises interior frame body 1, has the front end face 2 that runs through interior frame body 1, three cuboid inserting-plate holes 8 of rear end face 3 on the described interior frame body 1, and bulge loop 4 is arranged on the described front end face 2, the outer rim of three inserting-plate holes 8.The rear end face of described inserting-plate hole 8 is provided with three convex tendons 9 adaptive with the injection plug profile, and described three convex tendons place respectively between three inserting-plate holes 8 and are inverted-triangular.Be provided with contact chip buckle 5 in described inserting-plate hole 8, described contact chip buckle 5 is a pair of (two) symmetrically arranged hard plastic sheets.In the outside of described a pair of plastic sheet, respectively be provided with the salient point 6 of a circle by plug internal frame rear end face place, described one group of salient point 6 adopts and is symmetrical arranged.Contact chip 7 is assigned in the built-in contact chip buckle 5 of described inserting-plate hole 8.
When plug insertion socket, the set bulge loop of the front end face of interior frame body can provide for user's hand one to avoid the safe distance that gets an electric shock, and can guarantee on the other hand the steadiness of contact chip and expose size can be not long.The inserted sheet buckle is located at the inserting-plate hole inwall, and it is used for the installation location of inserted sheet, and what namely guarantee contact chip exposes the requirement of size conforms industry standard.Contact chip is stretched by the sheet of copper material and makes, and the size of contact chip and the size of inserting-plate hole are suitable, the contact chip inner end arrange one with the contact chip buckle on the adaptive hollow round hole of bump size.After contact chip pierced into jack, two salient points that the small sircle hole that the contact chip inner end has will be touched on the sheet buckle blocked, so that contact chip and buckle combine closely, then power line were received on the inner end of contact chip.The set convex tendon of rear end face can stagger affixed good power supply the end of a thread mutually, avoids electrode to cause danger because contacting with each other.Secondly, the outer rim of convex tendon is arranged to by interior curved shape structure toward outer incline provide preferably draw taper for the demoulding on the other hand outside can be suitable with the injection mould of box the plug.After power supply the end of a thread is secured to the inserted sheet inner end, just can carry out the injection moulding at the back of plug internal frame, realize the final molding of plug.
The utility model is compared with existing plug internal frame, can realize on the one hand the fixing fast of contact chip, can avoid after the convex tendon injection moulding on the other hand that water circulates when plug inside is intake between the utmost point and the utmost point, produce short circuit risk and cause insulation resistance little because leaking, do not reach the requirement of safety test.The utility model can be so that whole product be more practical, and electrical property is more stable, also simplifies significantly simultaneously the production process of product, has reduced Production Time and cost of labor.
Although above-described specific embodiment, it only is the utility model preferred embodiment, but should be understood that under the prerequisite that does not deviate from spirit of the present utility model and preset range, modification of the present utility model and change are contained by the scope of foregoing and appended claims.
