Abstract

(57) Abstract: An object of the present invention is to provide a rear portion of a micro terminal for enabling connection with a wiring in a plane lower than a plane of a support of the terminal in a concave portion when the terminal is inside the connector. In the area of shape improvement, the goal is to achieve coplanar coupling by two adjacent rows of terminals when two terminals are present in the connector. The rear area of this terminal is formed by a flat part which is an extension of the front area, the corresponding skirt lifts from both ends and the flat area extends into the elbow-shaped area, the only free end of the elbow-shaped area Extends to another plane area, and flat and flexible wiring is arranged over the plane area.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD OF THE INVENTION

The patent of the present invention enables, in particular, an electrical connection between the rear area of the microterminals and the flat wiring by means of ultrasonic or spray welding and also provides a mono-flat union of two adjacent identical terminal rows. It relates to the improvement of the rear area of the micro terminal to enable it.

[0002]

[Prior art]

The state of the art is known in the market as female terminals, which also have the function of enabling electrical connections between several assemblies of wiring in the terminals that interconnect the corresponding male and female terminals. Are present.

[0003] Among these types of terminals, in particular the female terminals, a front part for making the electrical connection itself between the female and male terminals, and a rear part acting as a connection between the electrical wiring and said female terminal. Are known.

In a known manner, the rear part is designed to be a small tongue-shaped concave area, which is formed by a conductive part of a wiring which has been deformed into an insulating or dielectric part. It is up.

[0005] Due to inexpensive procedures, operations, and continuous inspection of the product, in some cases, the coupling of the terminals and wires does not separate the conductive portions of the wires from the insulating regions or portions of the wires. Even now it can be done.

In such cases, the use of flat, flexible wiring for this type of connection is also known. This makes the welding operation itself easier because the rear part of the terminals is flat and the flexible wiring is also flat.

[0007]

[Problems to be solved by the invention]

It is an object of the present invention to design the rear portion to allow coupling with wiring in a plane lower than the plane of the support of the terminal in each recess when the terminal is inside the connector. The purpose of the present invention is to improve the shape of a part, and to connect two adjacent terminal rows coplanarly when the terminal is in the connector.

[0008]

[Means for Solving the Problems]

The rear area of the microterminal is formed by a flat portion which is an extension of the front area, and from the end of the front area a corresponding skirt is lifted, said front area extending into an elbow-shaped area, Has a single free end extending into another planar area through the flat, flexible wiring connected to the assembly for subsequent ultrasonic welding operations.

[0009] The elbow-shaped part used in the rear area of the terminal may, if it is in a recess, be flush with the corresponding support fitted to one end of the connector, to that effect. Is defined as the welding area.

[0010] Other details and features of the present invention patent will become apparent from the following description taken in conjunction with the accompanying drawings, which illustrate, in detail, the foregoing details. These details are given by way of example with reference to examples of possible embodiments and are not limited to the details outlined. Accordingly, the foregoing details are to be considered without any limitation from an exemplary perspective.

BEST MODE FOR CARRYING OUT THE INVENTION

In one preferred embodiment of the present invention, as shown in FIG. 1, the microterminal (10) is formed with a completely conventional front area (11), the front area comprising: ,
As shown in FIG. 2 and FIG. 3, the rear surface extends along the flat portion (13),
The skirt (14) rises from the periphery of ()) and extends (13) along the elbow-shaped area (15) and its only free end or flat area (16).

The purpose of the elbow (15) is to obtain a certain distance between the plane passing through the base of the front area (11) of the microterminal (10) and the plane area (16), as shown in FIG. As shown in FIG. 4, it is possible to carry out a coplanar or completely coplanar welding when the microterminal (10) is in the recess of any connector (17). is there. The method is such that the flat area (16) leans directly on the support (19) and, irrespective of the type of welding operation, this is firstly fully automated, and secondly,
Operating the welding tool in a complicated and prolonged manner in order to perform the welding operation between the flat area (16) and the flat and flexible wiring arranged on the support (19). It takes place in a minimum amount of time.

While the invention has been fully disclosed in accordance with the accompanying drawings, the invention has been provided, provided that any improvements contemplated do not depart from the essence of the invention patent as summarized in the claims. It will be understood that any detailed refinement can be introduced which is convenient for the present invention.
