The connector includes a first housing with a first engagement part. A holder is configured to be mounted to the first housing. The holder has a first mating part corresponding to the first engagement part. The holder has a second engagement part for engagement of the first engagement part and the first mating part.

Connector and locking fixture thereof

A molding machine comprising an injection portion with an injection nozzle which injects a molding material, a turntable comprising a rotation driving apparatus, a plurality of molds placed along a peripheral edge of the turntable, an attaching and detaching station, an injection station and a plurality of curing stations. Each mold comprises a material receiving port communicating with the injection nozzle when the mold is positioned at the injection station. Each mold further comprises a mechanism which close the material receiving port so as to prevent the molding material from flowing backward when the mold is separated from the injection nozzle. The molds are transferred by rotation of the turntable to each station one by one. Primary formed products are attached to the molds at the attaching and detaching station, injected at the injection station, cured to be second formed products at the curing stations and finally took out at the attaching and detaching station.

Molding machine

In a production apparatus ( ), after rear holders ( ) and a housing body ( ) are molded by molding die cavities, slides ( ) are moved apart from the housing body ( ). Then, cylinders ( ) are driven to move the rear holders ( ), holders ( ) and the slides ( ) together with slide plates ( ), so that the rear holders ( ) are located in opposed relation to the housing body ( ). Then, cylinders ( ) are driven to move the rear holders ( ) toward the housing body ( ), thereby provisionally retaining the rear holders ( ) on the housing body ( ). Therefore, the amount of movement of the slides ( ) is small, and it is not necessary to provide any space for holding the slides ( ), moved into their respective stand-by positions, and therefore the small-size design of the production apparatus can be achieved, and also the production efficiency can be enhanced.

Method of and apparatus for producing rear holder-attached connector

A method of producing a connector with a rear holder, wherein a housing 2 and a rear holder 3 are molded separately from each other by a set of molds 31 to 34. After molding, one of the molds (33) is moved to form a space between the housing 2 and the rear holder 3, and using another (34) of the molds, the rear holder 3 is moved toward the housing 2, thereby provisionally retaining the rear holder 3 on the housing 2.
