See also Fig. 3, Fig. 4 and Fig. 5, be to be the utility model first embodiment, it is to be double-deck USB electric connector, it is in order to be electrically connected a USB joint 35, this USB joint 35 is provided with at least one hole clipping 36, it includes: a plastics pedestal 40, four buckle elements 60, an earth element 70, two clamp elements 80, and a metal shell 90, wherein:
This plastics pedestal 40, be provided with at least two link slots 41 and most terminals 50 in it, the front end of this link slot 41 can supply this USB joint 35 for inserting mouth, please cooperate and consult Fig. 6 and Fig. 7, these each link slot 41 rears respectively are provided with two cover access slot 42 and stop surfaces 43,41 of two link slots are provided with a dividing plate 45, and this each terminal 50 is provided with that a contact site 51 is positioned at this link slot 41 and a pin portion 52 extends to plastics pedestal 40 lower ends.
Earth element 70 is a different elements with this metal shell 90, it is to make a shaped as frame plate with sheet iron, it is provided with a location division 72, this location division 72 cooperates two link slots 41 of plastics pedestal to be provided with two perforates 71, the periphery of this two perforate 71 is connected with several grounding elastic parts 75 and extends in this link slot, its location division 72 is positioned the front end of plastics pedestal 40, and pushes against by this majority grounding elastic part 75 and pedestal 40 elasticity.
By above structure, see also Fig. 8, when USB joint 35 inserts link slot 41 to the location, its upper and lower hole clipping 36 can be clamping part 65 buckles of buckle element 60, please cooperate and consult Fig. 7, stop because the stop section 63 of the fixed part of this buckle element 60 can be the stop surface 43 of plastics pedestal 40, it can not break away from from the direction of extracting of link slot 41, so when USB joint 35 was extracted, it still can firmly combine with plastics pedestal 40.
By above structure explanation, the utility model can be summarized following advantage:
1. metal shell 90 is to process one-body molded formation one no seam shell body with aluminium by aluminium extruded, and is so not only aesthetic in appearance, and screening effect is good, has splendid anti-electromagnetic interference effect.
2. on making, metal shell 90 is with aluminium extruded machine-shaping, and handling ease need not cut and the punching press bending, does not have waste material fully and need not and electroplate, and only need make simple anode treatment, significantly reduces manufacturing cost.
3. earth element 70, buckle element 60, and clamp element 80 is that metal shell 90 with aluminium is different elements, so, earth element 70, buckle element 60, and clamp element 80 only with a small amount of be suitable for rigidity or flexible metal material make again respectively with plastics pedestal 40 and cheaply the aluminium shell assemble and locate, so can be in order not satisfy earth element 70, buckle element 60, and clamp element 80 local stiffness such as grade or spring function demand and the monolithic case integrated punching is made, increase material and processing cost, so, metal shell 90 can utilize the aluminium extruded machine-shaping of low cost of manufacture.
4. this buckle element 60 is located to the assembling of link slot 41 directions by the cover access slot 42 at plastics pedestal 40 rears, so the stop surface 43 of plastics pedestal 40 can be barred from the stop section 63 of the fixed part 61 of this buckle element 60, make buckle element 60 strong fixs, can not extract direction and break away from from link slot.
(metal shell and buckle element and earth element are separated manufacturing by above explanation technical characterstic of the present utility model as can be known, again with plastics pedestal assembling location) obviously break through traditional technological thought (integrated punching goes out fastener spring piece and grounding elastic part on the metal shell), conventional art is for the integrated punching shell body, earth element, buckle element, and clamp element, having wasted a lot of earth resources increases costs and does not know, yet as long as the difference in functionality demand is achieved the goal by different elements respectively, can reduce manufacturing cost, save earth resource, therefore, the utility model can promote product efficacy really and reduce manufacturing cost, promotes the usability of industry.
