Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
With reference to Fig. 2, Fig. 3, a kind of cutter formula connector that provides for the utility model embodiment, it comprises insulating body 1 and is located at metal terminal 2 on the insulating body 1, described metal terminal 2 is formed by sheet metal 3 doublings, and is filled with between the both ends 31 after 3 doublings of described sheet metal and described insulating body 1 integrated plastic cement 4.
The cutter formula connector that the utility model provides, with after sheet metal 3 doublings as metal terminal 2, on the one hand, sheet metal 3 doublings, intensity is strengthened, the requirement of strength in the time of can satisfying connector and reliably connect, on the other hand, the existing relatively metal derby thin thickness of sheet metal 3, it is few to consume material, and cost is low; Sheet metal 3 can be a plurality of by the punching press one-shot forming because thin thickness is simultaneously, and one-time formed a plurality of sheet metal 3 can adopt the mode of embedding and injection molding and 1 injection moulding of described insulating body in one, not only improved packaging efficiency greatly, reduce production costs, be fit to produce in batches, and the finished product after the assembling is also more firm than the finished product of assembling in the prior art.
Particularly, with reference to Fig. 2, Fig. 3, form after described sheet metal 3 doublings bending end 32 and with described bending end 32 over against first openend 33, the upside of described bending end 32 and downside are respectively second openend 34 and the 3rd openend (not shown).When sheet metal 3 adopted embedding and injection molding with described insulating body 1, described first openend 33 was positioned in the mould of insulating body 1, and first openend 33 is embedded in the insulating body 1 after the moulding.By first openend 33 is embedded in the described insulating body 1, make first openend 33 of sheet metal 3 form relative closed state with bending end 32, like this, structure is more firm between the both ends 31 after sheet metal 3 doublings.
With reference to Fig. 3, in the present embodiment, 31 inboards, an end of described first openend 33 are provided with a projection 35.Replace mutually by described projection 35 between the described both ends 31, fill plastic cement 4, guaranteed that metal terminal 2 has certain thickness thereby form a predetermined space.In described space, fill plastic cement 4, on the one hand, strengthened the bonding strength between sheet metal 3 and the insulating body 1, make the connection of the two more firm; On the other hand, plastic cement 4 has also strengthened the intensity of metal terminal 2, the requirement of strength when making metal terminal 2 satisfy connector reliably to connect.
Referring again to Fig. 3, described bending end 32 is provided with an arc notch 36 with described second openend 34 junctions, and two edges of described second openend 34 bend inwards respectively, are filled with plastic cement 4 in the described arc notch 36., the edge of second openend 34 is bent inwards, when embedding and injection molding, sizing material can be wrapped in described second openend 34 better herein.And this arc notch 36 is set is that the edge of second openend 34 for convenience bends inwards, and when embedding and injection molding, also fills up sizing material in the described arc notch 36, and finally forms plastic cement 4.
Further, owing to can not merge mutually between metal and the plastic cement,, in the present embodiment, the sidewall of an end 31 of described sheet metal 3 is provided with through hole 311 for being connected between reinforcement metal sheet 3 and the insulating body 1.During embedding and injection molding, the sizing material of described insulating body 1 flows in the through hole 311, forms the plastic cement 4 that is embedded in the through hole 311 after the moulding.Like this, improved the adhesion between sheet metal 3 and the insulating body 1, sheet metal 3 is difficult for getting loose.
Further, owing to still have certain length after sheet metal 3 doublings in the present embodiment, for strengthening the bonding strength between whole sheet metal 3 and the insulating body 1, in the present embodiment, described through hole 311 is designed to a strip structure, and along described sheet metal 3 length direction settings.
Particularly, in the present embodiment, described insulating body 1 is rectangular structure, and the metal terminal 2 that is folded to form by sheet metal 3 is three, and is set in parallel on the long end face of described insulating body 1.Described metal terminal 2 also is not limited to three in the present embodiment, and it can design a plurality of according to actual needs.
In the present embodiment, metal terminal 2 forms for sheet metal 3 doublings than book, so metal terminal 2 preferred employing punch formings, stamping forming metal terminal 2 mechanical properties are better, the intensity height.Particularly, with reference to Fig. 4, Fig. 5, metal terminal 2 one ends after the punch forming are connected with strip 5, and described strip 5 is used for locating mutually with injection mold in the embedding and injection molding process, make described metal terminal 2 fixing in place, prevent that described metal terminal 2 is subjected to the impact of plastic cement melt and misplaces.After embedding and injection molding is finished, need metal terminal 2 by separating on the described strip 5.In the present embodiment, described strip 5 and metal terminal 2 junctions are to a lateral buckling and be provided with a breach 51, in breach 51 place's application of forces, can more easily metal terminal 2 be separated with strip 5.In the present embodiment, punching press simultaneously form a plurality of metal terminals 2 on the strip 5, a plurality of metal terminals 2 can be simultaneously by the mode of embedding and injection molding and 1 injection moulding of a plurality of insulating body in one, so can form a plurality of cutter formula connector finished products simultaneously, packaging efficiency improves greatly.
Below only be preferred embodiment of the present utility model,, all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model not in order to restriction the utility model.
