Abstract
The utility model discloses a waterproof switch cap head structure. In the waterproof switch of the existing house appliance, a copper cap head thereof is riveted with a plastic cap head inner plug by a small punching machine, the installing technique is complex and the riveted copper cap head is easy to fall. The technical scheme adopted by the utility model is as follows: the waterproof switch cap head structure comprises the copper cap head and the plastic cap head inner plug. The waterproof switch cap head structure is characterized in that the copper cap head is internally provided with a groove; a clamping part is formed at the upper part of the cap head inner plug; and a positioning groove matched with the clamping part is formed on the inner wall of the groove. The waterproof switch cap head structure effectively prevents the falling of the copper cap head, improves the quality of products, can adopt an in-mould injection-moulding technique for processing and simplifies the installing technique.
Description
Technical field
The utility model relates to water proof switch, specifically a kind of water proof switch cap header structure.
Background technology
Existing a household electrical appliance water proof switch, its copper cap head carries out riveted with plug in the plastic cap head with little stamping machine, the mounting process complexity, because copper cap head diameter of bore is too little, and the general instrument car can't reach dimensional requirement, the copper cap head behind the riveted comes off easily in addition.
The utility model content
Technical problem to be solved in the utility model is to overcome the defective that above-mentioned prior art exists, and a kind of water proof switch cap header structure that can prevent effectively that copper cap head from coming off is provided.
For this reason, the utility model adopts following technical scheme: water proof switch cap header structure, comprise plug in copper cap head and the plastic cap head, and it is characterized in that in the described copper cap head groove being arranged, the card division is formed at the top of plug in the cap head, forms the location notch that cooperates with the card division on the inwall of groove.By cooperating of location notch and card division, can prevent effectively that copper cap head from coming off, improved product quality, said structure can adopt in-mould injection technology to process, and has simplified mounting process.
Above-mentioned water proof switch cap header structure, two kinds of structures can be adopted in the card division: 1) card division is a snap ring, described location notch is the groove that a circle cooperates with snap ring; 2) card division is a plurality of fixture blocks, and the quantity of location notch is identical with the quantity of fixture block.The card division thickness that above-mentioned two kinds of structures adopt is 0.2-0.8mm.
The utlity model has following beneficial effect: prevent that effectively copper cap head from coming off, and improved product quality; Can adopt in-mould injection technology to process, simplify mounting process.
The utility model is described in further detail below in conjunction with specification drawings and specific embodiments.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is an assembling schematic diagram of the present utility model.
Embodiment
Water proof switch cap header structure shown in Fig. 1-2 has a groove in the copper cap head 1, and a snap ring 4 is formed at the top of plug 2 in the plastic cap head, forms the location notch that a circle cooperates with snap ring on the inwall of groove.The thickness range of snap ring is selected 0.2-0.8mm for use.
Manufacture method of the present utility model is as follows: fill in original cap head in the mold cavity in the mould according to copper cap head size earlier and produce location hole, then copper cap head is put into location hole and carry out injection moulding again, make and fill in directly moulding in copper cap head in the cap head.
Claims (4)
