Description

Connector

The present invention relates to a kind of connector, it is the free-ended protuberance that will approach cantilever beam shape elastic arm outstanding in outer shell passage, be embedded in the terminal recess that is housed in this passage, terminal is fixed in the passage, after accommodating terminal, form on the part simultaneously for stoping its fixed component that will constitute in addition to be installed in elastic arm to the generation displacement of the above-mentioned epistasis arm outside.

Known this kind of connector as United States Patent (USP) the 3rd, 686, shown in No. the 3rd, 601,760, No. 619 and the United States Patent (USP), in outer shell passage, needs terminal accommodating the protuberance of elastic arm is embedded in the recess of terminal, and the beginning is installed in shell with the said fixing member.

Present shell production line, terminal production line and the assembly line that terminal is assembled on the shell carry out in different places respectively, and are that the defeated duct device of mat carries out to the supply of the assembly line of shell and terminal.

In addition, the assembling that terminal is assembled to shell is tending towards carrying out with automatic production line gradually.

Above-mentioned traditional connector for shell is supplied with to assembling line, must be supplied with shell and the such two kinds of parts of said fixing member, will spend man-hour when therefore managing these parts.

In addition, in the time of the assembling work of having accommodated the shell of terminal and fixed component being carried out, need possess the equipment that fixture is directed to the shell rigging position on automatic production line, thereby make the assembling line scale become big.

First purpose of the present invention is to provide a kind of connector, be shell to be installed under the state of fixed component, it can be supplied with assembling line, and for the outer shell passage that is in installing fixed component state, can insert terminal same as before, simultaneously after inserting terminal, needn't consider that the direction that fixed component is assemblied in shell can implement.

Second purpose of the present invention is in order to ensure the sealing that supplies between the chimeric each other skirt section of paired shell, make the elastomeric closure member of ring-type mediate, be specially under the state before chimeric closure member in the fitting portion of shell is on one side prevented the device of living and the said fixing member is had an effect.

The 3rd purpose of the present invention be to make paired shell as mutual when chimeric guiding device and the said fixing member is played a role.

The fixed component of connector of the present invention and connector shell are to constitute the required temporary transient prevention of temporary transient installing and prevented device when the formation of the elastic arm of this fixed component on the cylindrical portion that constitutes the terminal accommodating passage partly departs to achieve these goals.

In addition, in connector of the present invention, on each paired shell, be configured such that its each mutual chimeric skirt section, in another side shell part that the skirt section surrounds by introducing the other side skirt section one side, and the skirt section of the other side's shell between be pressed into the elastomeric closure member of ring-type, and make a part that constitutes cylindrical body into the required coiling seat of coiling elastomeric closure member, in addition fixed component is constituted a frame shape shape that is capped until several of striding these cylindrical portion, and at its openend, fixed component is covered by above-mentioned cylindrical portion, when being installed in elastic arm when forming part and going up, forms with above-mentioned pedestal face quadrature and outstanding flange part.

In addition, connector of the present invention, be with a plurality of cylindrical portion, be set up in parallel at the side wall surface of the elastic arm that makes formation under state longitudinally, to being formed with suitable spacing mutually, on the fixed component in the shell on one side of paired shell the mutual fairlead of cylindrical portion that embeds with the another side shell is set with its orthogonal direction.

Prevent device by temporary transient the prevention with quilt, for the fixed component of on connector shell, temporarily being installed, be to be positioned to depart from the elastic arm formation part that is formed on the shell cylindrical portion sidewall, and terminal inserts the cylindrical portion internal channel, be that terminal is prevented in the free-ended protuberance that is formed on elastic arm, proceed to the state of displacement outside cylindrical portion at the free end that makes above-mentioned elastic arm.During assigned position in terminal moves to passage, the protuberance that is installed in free end of elastic arm becomes and is entrenched on the recess that is formed on the terminal, and the free end of elastic arm forms part to original cylindrical portion sidewall and returns.

The fixed component that forms behind the state like this is disengaged temporary transient installing state, and the elastic arm that is moved to the cylindrical portion sidewall forms on the part, for shell for formally being prevented.

The fixed component of formally being prevented is that the elastic arm that is positioned at above-mentioned cylindrical portion sidewall forms on the part, has the effect of prevention towards the displacement of elastic arm cylindrical portion outside.The elastomeric closure member of ring-type be fixed component by the process before temporarily being installed in shell in, be wound in the coiling seat in the skirt section that is located at shell, and when the fixed component following formula is installed in shell, can be by being formed on the flange on the frame shape fixed component openend, and prevent that it from coming off on the coiling seat that is supported.

Fairlead is that the connector that will have fairlead is when being connected in the other side's connector, be inserted into be located at the other side's one side-connector cylindrical portion mutually between set gap, both interosculate and make the skirt section, Yi Bian make connector mutually on one side in addition chimeric relative to each other on coaxial simultaneously.

When the mutual chimeric direction of connector was restricted on coaxial with the skirt section because of above-mentioned fairlead, terminal began to contact with each other.

Referring now to accompanying drawing embodiment is described.
