[embodiment]
The present invention will be further described below in conjunction with accompanying drawing:
In order to solve in the prior art direct current electric connector body and wire rod are adopted spot welding; it is low to be cured when realizing the assembling of direct current electric connector with this production efficiency by UV glue; the profile of solidifying the back product is not easy control; wire rod is subject to external force and pulls a little less than the protective effect; very high this technical problem of overall production cost the invention provides a kind of assemble method of direct current electric connector.
The assemble method of described direct current electric connector specifically comprises step: the first step, direct current electric connector body 101 and wire rod 102 are welded; Second step, the described stream electrical connector body 101 that will weld after getting well encapsulate with the mode of described wire rod 102 by low pressure injection formaing, realize the assembling of described direct current electric connector with this.Wherein, described second step is specially: the working chamber 104 of mould 105 is put in the described direct current electric connector body 101 after will welding well and the welding position of described wire rod 102, add the encapsulation base material, at injection pressure is to solidify second through 5-50 under the 1.5-40bar, realizes the assembling of described direct current electric connector with this.
Technical solution of the present invention in the prior art with direct current electric connector body 101 and wire rod 102 by UV adhesive curing encapsulation after; the profile of product is not easy control; wire rod 102 is subject to external force and pulls the more weak technical problem of protective effect; adopt polyamide hot after fusion, only to need very little pressure that it is trickled in very little mould 105 spaces; thereby can not damage the fragile components and parts that need encapsulation; reduced percent defective dramatically; and the profile of encapsulation back product is carefully and neatly done; the PUR good toughness; the intensity height; encapsulation back wire rod 102 is difficult for being pullled by external force, and born to pull strength bigger.
Has good adhesive property after the polyamide hot fusing, can play sealing to the described direct current electric connector body 101 and the junction of described wire rod 102 effectively, moistureproof, waterproof, the effect of dustproof and resistance to chemical attack, anti-ambient temperature range is at-40 ℃ to 150 ℃, go for various abominable production environments and environment for use, hardness after the polyamide hot moulding can reach Shore A 60～90 or Shore D 40, and has good toughness, can slow down the impulsive force that comes from the outside, and polyamide hot also has good flame retardant property, do not contain any solvent, nontoxic, have very high environmental protection standard.
In the preferred technical solution of the present invention, described mould 105 is a cast-aluminum die, sees also Fig. 2, and as shown in the figure, the mould closing section 106 at described cast-aluminum die is inlaid with the protective layer that Cu alloy material or steel are made.Mould 105 adopts Cast Aluminum Dies, rather than steel, so be highly susceptible to design, exploitation and the processing and manufacturing of mould 105, can shorten the construction cycle.
Traditional UV point adhesive curing mode, according to per 10 mistake UV stoves, and the time of every 1 needs is about 10 seconds, and the time that crosses the UV stove is 120 seconds, and the production time of each finished product is 220/10=22 second like this.And after the employing technical solution of the present invention production time of product be 19 seconds, if doing the time of each according to present 105 two working chambers 104 of a mould is 9.5 seconds, if doing the time of each finished product according to 105 4 working chambers 104 of a mould is about 5 seconds, improved production efficiency greatly.
Use the glue consumption of each product of UV glue to be about 0.5g, according to the market price technology, the cost of each product is 0.5 yuan.And after the employing technical solution of the present invention, the unit price of PUR is that 200 yuan/kg (containing tax 17%) goes up use 1g with 1, and waste material is that 1g is an example, the 1kg sizing material can be done 500,1 sizing material cost is so: 200 yuan/500=0.40 unit, consider that amount of product throughput is huge, can save a large amount of production costs.
The present invention also provides a kind of direct current electric connector, the structural representation of described direct current electric connector can be consulted Fig. 1, as shown in Figure 1, direct current electric connector comprises: direct current electric connector body 101, wire rod 102 and membranaceous connector 103, described membranaceous connector 103 is regular is wrapped in the outer surface of described direct current electric connector body 101 and described wire rod 102 welding positions.
At membranaceous connector 103 described in the preferred technical solution of the present invention is polyamide hot.
Described direct current electric connector profile behind the employing technical solution of the present invention assembled formation is carefully and neatly done, can promote the quality of product, and polyamide hot is tight to the parcel of direct current electric connector body 101 and wire rod 102 welding positions, wire rod 102 does not have and leaks outside, so just reduced the fraction defective of product, can make the product appearance of respective standard according to specification requirement, thereby effectively overcome in the prior art, the point adhesive curing method that adopts the UV curing mode and cause is irregular, to the parcel weak effect of direct current electric connector body 101 and wire rod 102, high this technical problem of product fraction defective.
Above content be in conjunction with concrete optimal technical scheme to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
