Title: Improvements in or relating to electrical connectors
IPC: H01R13/422
Filed: 1962-09-21
Abstract: 990,300. Injection moulding electrical articles. CANNON ELECTRIC CO. Sept. 21,1962 [Sept. 25, 1961], No. 36081/62. Heading B5A. [Also in Division H2] A method of making a resilient insulator for an electrical connector comprises the steps of supporting a contact positioning web 28 (Fig. 3) of insulating material in a mould cavity 56, which has a plurality of parallel core pins 44, 62 (Fig. 5) extending therethrough, web 28 comprising a plurality of substantially rigid stop members 22 each of which is disposed in the mould on a respective core pin 44 and a plurality of bridging members 30 which connect step members 22 together. Resilient elastomer material is then injected into mould cavity 56 to form the insulator, the elastomer material is cured in bonded relationship with web 28, and the insulator removed from the mould. The core pins 44, 62 form a plurality of contact terminal receiving bores through the insulator with stop members 22 presenting stop shoulders in the respective bores intermediate the ends of the bores which are engageable against opposed shoulders on respective contact terminals to limit axial movement of the contact terminals in one direction in the bores. The resilient body of the insulator is made of any desired elastomer insulation materials such as neoprene, natural rubber, silicone, polyurethane, " buna"-S and "buna"-N (Registered Trade Mark). A formula for moulding the body is given together with a preferred milling procedure for combining the ingredients. Bridging members 30 are thinner and weaker than stop members 22 so that they break or shrink or bend when the moulded body cools. Suitable thermoplastic materials for web 28 are nylon, Lexan and " Delrin " (Registered Trade Mark), or thermosetting plastics could be used. A coating of bonding material is applied to web 28 before it is inserted in the mould. Any suitable bonding agent may be used, suitable materials being chemlock No. 203 and chemlock No. 220. If web 28 is of thermosetting plastics material the coating of bonding materials could be eliminated. A suitable mould shown in Figs. 1, 5 has a back-up plate 38, on insert holder plate 40 supporting a pin mounting insert 42 within which a plurality of core pin members 44 are mounted. A mould cavity plate 54 has a cavity 56 and another insert holder plate 58 supports a pin mounting insert 60 which supports a multiplicity of core pin members 62 which, when the mould is assembled, mate with core pin members 44. A back-up plate 68 has a cylindrical recess 70 within which the elastomer insulating material is placed. A plunger 80 of an hydraulic press forces piston 78 downwards into recess 7 to inject the elastomer material through the channels 72, 74, 76 into mould cavity 56. The various parts are aligned by dowels 82. The resulting connector is described (see Division H2).
