Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a connector terminal used for a stacking connector or the like.

<Prior Art> Conventionally, a stacking connector has been used to simultaneously connect a plurality of external devices. This connector
To be used by being connected to each other, it has a male terminal on one side and a female terminal on the other side. In the connector,
As shown in FIG. 8, a male terminal 51 and a female terminal 52 are connected to each other by a covered electric wire 53 in a connector, and one of the connecting portions has a covering drawn out to connect an external device. The electric wire 54 is crimped together with the covered electric wire 53. When inserting an element such as a resistor or a condenser between the male terminal 51 and the female terminal 52, as shown in FIG. 9, the element 55 is soldered between the bisected covered electric wires 53. It

<Problems to be solved by the invention> Such a conventional connector terminal is divided into a male terminal 51 and a female terminal 52, and not only has a large number of parts but also requires double crimping work for connection. However, this leads to an increase in man-hours. Moreover, in the double crimping work, since the thickness of the electric wire to be crimped is different between the male terminal 51 and the female terminal 52, it is necessary to adjust the crimping machine, resulting in a further increase in the number of working steps.

The present invention has a small number of parts that solve these problems,
It is an object of the present invention to provide a terminal for a connector which can be easily connected and in which an element such as a resistor or a capacitor can be easily inserted between a male terminal and a female terminal.

<Means for Solving the Problems> A connector terminal according to the present invention has a male terminal portion formed at one end and a female terminal formed at the other end, and
A terminal for a linear connector in which an electric wire clamp portion for crimping and connecting an electric wire is formed at the base end portion of the female terminal portion, and one of the elements such as a resistor and a capacitor is provided at the base end portion of the male terminal portion. A U-shaped portion to which the lead is connected is formed, and a flat plate portion to which the other lead of the element is connected is extended between the U-shaped portion and the electric wire clamp portion. A round hole has been opened.

<Operation> Since the male terminal portion and the female terminal portion are integrated, no wiring work is required when the electric wire for external drawing is not connected. When connecting an electric wire for external drawing, the wire connection work can be completed simply by fixing the electric wire to the electric wire clamp portion.

When connecting an element such as a resistor or capacitor between the male and female terminals, one lead is connected to the U-shaped part,
The other lead is connected to each of the round holes of the flat plate portion to cut between the U-shaped portion and the flat plate portion.

<Example> Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a plan view of a connector terminal showing an embodiment of the present invention, FIG. 2 is a side view, FIG. 3 is a plan view showing an example of a usage state, and FIGS. 4 and 5 are other uses. It is a top view showing a state.

The connector terminal 10 is a pin body formed by molding a metal plate, and has a male terminal portion 11 having a tubular shape and a hemispherical tip at one end side thereof.
Are formed. The other end is a tubular half-divided female terminal 12 having an open tip, into which a male terminal of another connector terminal is inserted.

An electric wire clamp portion 13 is formed between the male terminal portion 11 and the female terminal portion 12 for connecting the covered electric wire 20 for external drawing. The electric wire clamp portion 13 includes a first crimping portion 13a for crimping the core wire portion 21 of the covered electric wire 20 and a second crimping portion 13b for crimping the covering portion 22 of the covered electric wire 20,
Both are U-shaped and are arranged in the axial direction of the connector terminal 10.

From between the male terminal part 11 and the wire clamp part 13,
14 extends in a direction perpendicular to the axis of the connector terminal 10. The flat plate portion 14 has elements 30 such as resistors and capacitors.
Is provided with a round hole 14a for soldering. A U-shaped portion 15 is also formed near the base of the male terminal portion 11 for soldering the element 30.

The connector terminal 10 having such a configuration is used as follows.

When not using the covered electric wire 20 for external extraction, that is, when only connecting the male terminal portion 11 and the female terminal portion 12,
Since both are integrated, no wire connection work is required, and as shown in FIG.
The connector terminal 10 can be used only by crushing the second crimp portion 13b.

When using the coated electric wire 20 for external drawing, as shown in FIG.
The covered wire 22 is connected to the wire clamp portion 13 by crimping to the crimping portion 13a and crimping the covering portion 22 to the second crimping portion 13b.

When using element 30 such as a resistor or capacitor,
As shown in the figure, the element 30 is connected to the flat plate portion 14 of the flat plate portion 14 and the U
The connector terminal (10) is cut between it and the groove (15). By doing so, the male terminal portion 11 and the female terminal portion 12 are connected to the element 30.
Connected via.

FIG. 6 is a sectional view of a stacking connector using the connector terminal 10 and FIG. 7 is a connection diagram.

The stacking connector 40 has a rectangular parallelepiped case 41,
It has a pair of bodies 42a and 42b housed inside. The pair of bodies 42a and 42b are configured to hold 15 connector terminals 10, and one body 42a is formed in a concave shape and the other body 42b is formed in a convex shape. The male terminal portions 11 of the fifteen connector terminals 10 project into the concave portion of one body 42a. The female terminal portion 12 of the connector terminal 10 penetrates through the convex portion of the other body 42b, and the convex portion projects outside the case 41 so as to be fitted into the concave portion of another stacking connector.

Nine of the fifteen connector terminals 10 are not connected to the covered electric wire 20 for external extraction, and are used only by crushing the first crimping portion 13a and the second crimping portion 13b of the electric wire clamp portion 13. Has been done. The remaining 6 terminals 10 for the connector are connected to the covered electric wire 20 for external drawing.
An element 30 such as a resistor or a capacitor is connected to one of them. The covered electric wires 20 connected to the six connector terminals 10 are pulled out of the case 41 as a binding cord 43, and a 6-pin terminal portion 44 for connecting an external device is connected to the tip thereof.

Multiple stacking connectors for a single electronic device
By connecting 40 in series and connecting each terminal portion 44 to an external device, a plurality of external devices are simultaneously connected to a single electronic device.

In the above embodiment, elements such as resistors and capacitors are used.
Although soldering is used for connecting 30, pressure welding or the like can be used instead of soldering.

Further, the use of the connector terminal 10 is not limited to the stacking connector.

<Effects of the Invention> The connector terminal according to the present invention has a small number of parts and a low manufacturing cost because the male terminal portion and the female terminal portion are integrated. In addition, it is not necessary to connect the male terminal part and the female terminal part to each other when assembling the wiring, and when connecting the covered electric wire for external drawing, the covered electric wire can be connected to the electric wire clamp part independently. Since it does not require adjustment of the crimping machine and the like, it is extremely easy to assemble and assemble the wiring, which also enables cost reduction.

Also, connect an element such as a resistor between the flat plate portion and the U-shaped portion,
By cutting between the flat plate portion and the U-shaped portion, the element can be easily inserted between the male terminal portion and the female terminal portion.
