Description

Wire Handling Elements, Electrical Connectors & Cable-Connector Assemblies {WIRE MANAGEMENT MEMBER, ELECTRIC CONNECTOR AND CABLE-CONNECTOR ASSEMBLY}

FIELD OF THE INVENTION The present invention relates to electrical connectors and cable-connector assemblies, and more particularly to wire processing members for use with electrical connectors and cable-connector assemblies.

Electrical connectors generally comprise a rectangular electrically insulated connector housing. The connector housing includes a plurality of terminals. Each terminal has a tail suspended from the air to extend from one end of the connector housing and to solder to the respective wires of the cable. Since the tails of each terminal are suspended in the air, it is difficult to solder the wires of the cable to the tails of the respective terminals and one wire of the cable may be inadvertently soldered to two or more terminals.

The present invention has been carried out to provide an electrical connector and a cable-connector assembly which obviate the aforementioned problems.

It is an object of the present invention to provide an electrical connector and cable-connector assembly having a wire processing member for accommodating and supporting the tail of each terminal while preventing the tail of each terminal from hanging in the air.

Another object of the present invention is an electrical connector and cable-connector assembly having a wire handling member for receiving and supporting the wires of the cable, while allowing the wires of the cable to be arranged in good condition for soldering to the tail of each terminal accurately and quickly. To provide.

It is another object of the present invention to provide an electrical connector and cable-connector assembly having a wire treatment member that keeps each wire of the cable isolated from each other in order to achieve better electrical properties.

Compared with prior art connectors having wire processing members engaged with recesses in the outer wall of the connector housing, another object of the present invention extends from the surface of the wire processing member to be received inside each cavity of the connector housing. An electrical connector and cable-connector assembly having a wire treatment member having one or more positioning rods is provided. This configuration is particularly advantageous for very small connectors where it is impractical to couple the wire processing system with the outer wall of the connector body. Moreover, the present invention is advantageous over the prior art because the tooling for manufacturing the connector housing and the wire treatment member can be simplified.

To achieve these and other objects of the present invention, an electrical connector is provided that includes a connector body and a wire processing member. The cable-connector assembly also includes a connector body, a cable, and a wire treatment member. The connector body includes terminals inserted therein. Each terminal has a tail extending from one end of the connector body for electrical soldering to respective wires of the cable. The wire processing member is connected with the connector body by positioning rods received inside the cavities of the connector body. The wire processing member is configured to receive the tails of the respective terminals so as to prevent the tails of the respective terminals from hanging in the air, and the wires of the cable so that the wires can be reliably soldered to the tails of the respective terminals, respectively. It may include a plurality of wire grooves configured to receive the. Ribs may be located between adjacent terminal grooves to prevent solder directed to one of the terminals from moving to the other terminal. The wire treating member may be fabricated to have multiple platforms disposed at different heights for receiving terminals of vertically spaced rows.

Features of the invention which are considered to be novel are explained in detail in the appended claims. The present invention, together with its objects and advantages, may best be understood by the following detailed description taken in conjunction with the accompanying drawings, wherein like reference numerals denote like elements in the drawings.

1 to 3, the cable-connector assembly according to the present invention generally comprises a connector body 1, a cable 2 and a wire treatment member 3. The connector body 1 includes an electrically insulating housing 10 having a plurality of outer walls, terminal passages 12 inside the housing, and a plurality of terminals 11 inserted in the terminal passages 12, respectively. The connector may also include a metal shield (not shown) covering at least a portion of the housing 10. The electrically insulating housing 10 includes a plurality of positioning cavities 14, the purpose of which will be described later. The tail 110 of each terminal 11 extends from one of the outer walls of the housing 10, respectively, for soldering to the cable 2. The cable 2 comprises an electrically insulating jacket 20 and a plurality of wires 21 extending from the jacket 20. Each wire 21 includes a metal conductor 210 that is soldered to the tail 110 of its corresponding respective terminal 11.

The wire processing member 3 for use with the housing 10 includes a body portion having a plurality of terminal grooves 30, a plurality of wire grooves 31 and at least one positioning extending from an outer surface of the wire processing member. Rods 32. In the embodiment shown in FIGS. 1-3, the positioning rods 32 extend from the front of the wire processing member 3 in a direction approximately parallel to the terminal grooves 30. The positioning rods 32 are each accommodated in the positioning cavities 14 of the housing 10 of the connector body 1, allowing the wire processing member to be properly arranged in the housing 10 and securely fixed thereto. Although the terminal passage 12 and the positioning cavity 14 are shown in FIG. 1 as being connected, the terminal passage 12 and the positioning cavity 14 may be separated from each other.

The terminal grooves 30 are configured to receive the tails 110 of the respective terminals 11. Ribs 33, which can be integrally molded with the wire processing member 3, are located between adjacent terminal grooves 30. The ribs 33 are higher than the height of the tail 110 of each terminal 11 housed inside the terminal groove 30 so that the ribs 33 prevent the solder paste from moving to the adjacent terminal grooves 30. do. One end of each of the terminal grooves 30 is connected to the wire grooves 31, respectively.
