Join Fig. 9,3 rear end of metallic shield piece has extended downwardly a pair of of grounding leg 31.
Refering to Fig. 4, the interior iron-clad 5 be equipped with tubular main part 52, positioned at 52 rear of main part lift unit 53, It is formed in the through slot 51 between the main part 52 and lift unit 53 and with the holding tank 111 perforation.The main part 52 On be inwardly equipped with several clamping parts 521.53 upper surface of lift unit be higher than 52 upper surface of main part, 53 liang of sides of lift unit to Under be extended with a pair of of installation foot 532.
In conjunction with Fig. 4 and Figure 10, the shell 6 includes the integral reinforced sheet 61 and insulation shell 62 of injection molding.It is described exhausted Edge shell 62 includes sleeve part 620, a pair of of the mounting portion 624 extended from 620 liang of lateral sides of the sleeve part, from the sleeve part The outwardly protruding front limit portion 621 in 620 front ends, rear limiting section 622 and it is formed in the front limit portion 621 and rear limiting section 622 Between limiting slot 623.Stage portion 625 is formed on the inside of the insulation shell 62.It is equipped with inside insulation shell 62 and extends along the longitudinal direction To enhance the fin 626 of fixing power.If the reinforced sheet 61 is equipped with tabs 611 and extends downwardly from the tabs 611 Dry holding parts 612.
Refering to fig. 1 to Figure 11, the manufacturing method of the electric connector 100 sequentially includes the following steps.
Step a: Terminals Die group 10 is made by injection molding.Terminals Die group 10 can be by insulating body 1, two rows of terminals 2, gold Belong to and being formed after being molded closure die hole again after shielding 3 single injection-molded of piece.Alternatively, Terminals Die group 10 can also first form including Lower die group of the upper body 1a with the upper mold group of upper row's terminal 2 and including lower body 1b Yu lower row's terminal 2, metallic shield piece 3 is pressed from both sides It is held between upper mold group and lower die group, upper body 1a and lower body 1b is enabled to buckle by hook 14 and card hole 15, then by again Secondary injection molding enables upper mold group, lower die group and the molding of metallic shield piece 3 be integral.The material being molded again forms injection molding ontology 1c. Two kinds of molding modes all need to enable the pedestal 11 to be equipped with holding tank 111, and enable wherein one section of interconnecting piece 22 of each terminal 2 Surrounding is all in that hanging shape is exposed to the holding tank 111 to which attached portion 221 is wrapped up in formation.
Step b: interior iron-clad 5 is provided and interior iron-clad 5 is sheathed on the Terminals Die group 10.The clamping part 521 of iron-clad 5 in enabling It is snapped in the buckle slot 112 of the insulating body 1.A pair of of bending part 531 is enabled to be embedded in the groove 113 of the insulating body 1.It provides Reinforced sheet 61 and in being molded insulation shell 62 on the reinforced sheet 61 so that the shell 6 be made.The holding parts 612 are enabled to be embedded at The sleeve part 620 is to enhance the fixing power of reinforced sheet 61 Yu insulation shell 62.Insulation shell 62 is due to there is reinforced sheet 61 to be molded over one It rises and its intensity is enabled to be improved.The shell 6 is sheathed on outside the interior iron-clad 5, enables interior 5 front end of iron-clad be held in described exhausted The stage portion 625 of edge shell 62.
Step c: it in 11 back lower place of pedestal injection glue and enables glue fill the holding tank 111 and enters the through slot 51 to form waterproof portion 7, as shown in Figure 10, so that the part for being located at 11 lower section of pedestal for enabling waterproof portion 7 is in rearward to open Shape is put, i.e., does not have obstacle below, lower edge and side edge are attached in the insulation shell 62 and 5 rear end of interior iron-clad.It fills After the completion of glue, the glue is enabled to wrap up each surrounding for wrapping up in attached portion 221.The waterproof portion 7 is located at 11 top of pedestal Part reach the through slot 51 to be limited between the insulation shell 62 and the lift unit 53 of the interior iron-clad 5, upper end It is attached in the reinforced sheet 61.Waterproof portion 7 is plugged between the shell 6 and Terminals Die group 10 in wall shape, all round closure in In the inner surface of the shell 6.In addition to glue in this step, it is possible to use liquid-state silicon gel etc. is different from the plastic cement of insulating body 1 Other waterproof materials of material.
Step d: a water proof ring 8 is sheathed on to the limiting slot 623 of the insulation shell 6.Alternatively, water proof ring 8 can also by It is poured the waterproof materials such as glue, resin, liquid-state silicon gel in the limiting slot 623 and is formed.Step d can occur in shell molds 6 Step b in, may also occur at after step c.
Interior iron-clad 5 and shell 6 are all installed on after the Terminals Die group 10 encapsulating again, and the waterproof portion 7 is enabled to block in wall shape So as to blocking the gap between terminal base 10 and interior iron-clad 5, shell 6 between the shell 6 and Terminals Die group 10.Encapsulating 11 back lower place of Shi Xiancong pedestal pour into waterproof material so that 11 back lower place of pedestal waterproof portion 7 in backward open shape, behind Do not stop, operation is so enabled to be easy to carry out.The attached portion 221 of wrapping up in of terminal 2 is wrapped up by glue, rather than is wrapped up by insulating body 1, such as , when product crosses high temperature, waterproof material is not easy to remove with terminal 2, so that it is guaranteed that good waterproof effect for this.
