Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to connectors, and particularly, but not exclusively, to electrical connectors that include removable male and female components.

Many of the connectors using summer and summer connectors require similar protection of the contact areas, and also require protection to a certain extent from the effects of vibration.

OBJECTS OF THE INVENTION It is an object of the invention to provide a connector suitable for use as described above.

SUMMARY OF THE INVENTION According to the present invention, there is provided a connector of the type in which a male contact member and a female contact member are each housed within an electrically insulating housing, one of the housings being parallel to the contact member. and the other housing has a protective member extending parallel to the contact member in the longitudinal direction, and the protective member closes the opening when the connector assembly is assembled. formed as,
This provides a connector in which the combined contacts are substantially ll1lpA within the box formed by the two housings.

Preferably, said one housing has a plurality of latching members that cooperate with a corresponding plurality of indentations formed on the other housing to hold the assembly in a coupled condition.

At least one of the housings may include one or more latch members that cooperate with an aperture formed in the panel to position the connector relative to the panel. The housing may also include a boss formed to be inserted into a corresponding 1 m opening formed in the panel for longitudinally positioning the connector.

The connector according to the invention will be explained below by way of example with reference to the accompanying drawings.

1 凰1 First, referring to FIGS. 1 and 2, the female part of the connector includes a housing (FIG. 1) and contacts (FIG. 2).

This housing is molded from a plastic material and is an IJfI opening box with an opening extending the entire length on the lower surface. It will be appreciated that such a configuration is extremely easy to mold. The contacts are fitted into the housing by insertion through the openings.

To retain the contacts within the housing, the rearward portion of the housing has a keyhole shape (as shown in FIG. 3). The wall made of plastic flexes to allow the connector to pass through and restores to grip the contacts around the cylindrical part 3. The extending portion 4 of the contact fits into an opening 5 formed in the housing to prevent the contact from moving forward and backward.
The flat side wall portion 6 cooperates with the wall surface of the housing to prevent rotation of the contact member.

As can be seen in FIG. 2, a soldering tag 7 is provided for bonding the wires.

However, it is noted here that wire wrapping and crimping can be used with appropriate modification of the contact members. In addition, it is possible to provide the contact with a coupling function that removes the insulation.

Referring again to FIG. 1, a boss 8 is provided which is adapted to fit into a circular opening formed in a panel (not shown) to position the connector and prevent movement in the front and back direction. It is noteworthy that Additionally, one or more of the above number of clips 9 (only one shown) are provided, which clips 9 are inserted into corresponding openings to attach the connector to such panel. It is. The displacement that allows insertion and restoration of the clip depends entirely on the elasticity of the plastic material of the connector.

The contact portion of the housing is provided with a pair of serrations 10, which are used to prevent the male and female parts of the connector from coming apart when they are assembled. It cooperates with a clip (designated 11 in FIG. 4).

Now, referring to FIGS. 4 and 5, the male connector parts are the housing (FIG. 4) and the contact member (FIG. 5).
It is composed of:

This contact member is fitted into the housing by sliding it into the housing from the dominant side of the housing, without forcing the transverse piece 13 of the housing away so that the lip portion 12 enters the opening 14 and moving the contact backwards. Hold it like this. A shoulder 15 cooperates with a wall 16 of the housing to prevent it from sliding forward. The tip portion (contact portion) of the contact member is inserted through an opening 17 formed in the wall portion 16 and projected onto the support member 18 .

To facilitate assembly and disassembly of the connector assembly,
A finger grip 19 is provided on the body of the housing.

It is noted that the male contacts have solder tags similar to those provided on the female contacts. Again, any other suitable coupling method may be provided.

Regarding the assembly numbers of the male and female parts of the connector,
In addition to the contact portions of the two mating contact members, the support member 18
is inserted into the m1 mouth side of the female housing. This member 18 has two purposes; the first is to form a protective box portion surrounding the contacts, and the second is to support the lower lip 2o, thereby protecting the female contact member. The purpose is to prevent excessive stress from occurring at the branching portion of the pipe.

When assembly of the connector is completed, the clip 11 engages within the knurling 'J' 10, thereby preventing the two halves from being unduly separated. Once again, the elasticity of the plastic material prevents this from happening. It is used to engage the clip and return it to the initial position.Clip member 11
By tapering the tip edge of the blade, it is possible to facilitate its movement in the forward direction.

According to the connector housing of FIGS. 1 and 4, an extended insulating portion 21 is provided to cover one side 4 of the coupling tab 7, which helps prevent short circuits from occurring. .

Referring now to FIG. 6, another male contact housing is shown in which a plurality of male contacts are mounted side by side. We do not consider it necessary to further describe the housing of FIG. 6, as its function and its manufacture will become clear by reference to the description of FIG. 4.

FIG. 7 shows a male contact housing adapted to form a stack of connectors.

In this embodiment, the housing has a spigot I-22 and opening configuration such that the spigot of the lower connector fits into the opening formed in the upper connector to retain the stack. There is.

The connector described above is particularly suitable for the interconnection of ribbon cables, the housing being easily formed from nylon or polyester materials and the contact members being molded of e.g. a copper alloy with the contact parts plated with a precious metal such as gold. .
