Description

[Detailed Description of the Invention] The present invention relates to a connector for electrically separating and connecting devices and units of various electronic devices.

A conventional connector is formed by caulking and fixing a covered lead wire 6 to a terminal 2, as shown in FIGS. 6 and 7, and housing the required number of terminals 2 with lead wires in a case 1.

As is well known, the coated lead wire does not have a coating layer fixed to the conductive wire, but simply covers the conductive wire with the coating layer. Therefore, if the length of the covered lead wire is short, when the covering layer at both ends of the lead wire is peeled off to expose the conductive wire, a necessary portion of the covering layer may also come off from the conductive wire.

Therefore, there is a limit to how short the lead wires used in the connector can be, and they may be forced to be longer than necessary.

Even something as trivial as the length of the lead wire can hinder the miniaturization of products, which is one of the most important development goals for electrical products.

Furthermore, in the past, manual work was required to insert the terminal 2 to which the covered lead wire was connected into the case 1, which was inefficient. Furthermore, in the past, processing on the lead wires, such as shorting some of the lead wires together, was difficult due to the presence of a coating layer and the lack of directionality in bending the lead wires, making it impossible to stably support them. .

One possible way to solve the above problem is to form the terminal 2 and the strip-shaped conductor 3 integrally, as shown in FIG. However, in this case, considering that the expanded terminal 2 and the strip-shaped conductor 3 are formed by punching out the metal plate 5, as shown by the two-dot chain line, the yield of the material is poor, and this is not a good idea.

The technical problems to be solved by this invention are to be able to keep the number of conductors protruding from the terminals to the necessary minimum, to be able to insert the required number of terminals with conductors protruding into the case at once, It is possible to easily process the conductor, improve the yield of the material, and improve the flexibility for wiring by forming the conductor so that it is easy to bend.

In order to solve the above technical problem, the connector of the present invention forms each conductor into a strip shape, connects all the conductors together by connecting one end of each conductor to a connecting piece, and connects all the conductors as one body to the case side of the conductor. Narrow part 3 at the proximal end of
5 is formed.

The free end of each conductor is fixed to the terminal by caulking, and the terminals are lined up in a row, allowing multiple terminals to be inserted into the case at once, increasing work efficiency.

Next, by separating the connecting piece leaving only the required length of each conductor, each conductor can be freely connected to a mating member, and the length of the conductor can be kept to the minimum necessary.

Since the conductor is formed in a band shape, there is a certain degree of directionality in the bending direction, and the conductor can be stably supported, especially before the connecting plate is separated, so that it can be easily processed into a conductor. However, since the base end portion of the band-shaped conductor 3 is formed narrowly, it is easily bent and wiring is facilitated.

Since the terminals and conductors can be made by punching out separate conductive plates, yields can be increased.

The present invention will be specifically described below based on embodiments shown in the drawings.

As shown in FIGS. 1 and 2, the connector has a plurality of terminals 2 inserted into a case 1 and a strip-shaped conductor 3 protruding from the terminals 2. As shown in FIGS.

The terminal 2 is made by punching out a metal plate 5 and bending it to match the outline of the terminal 2a in the unfolded state, as shown by the two-dot chain line in FIG. A plurality of terminals 2 are manufactured so as to be connected together by connecting pieces 41, and after bending, the connecting pieces 41 are separated.

A pair of caulking pieces 21, 21 are formed at the base end of the terminal 2.

The conductor 3 has a strip shape with a thickness of 0.1 to 0.2 mm and a width of about 2 mm.

The conductor 3 is manufactured by the following procedure and fixed to the terminal.

As shown in FIG. 5A, a conductive member 4 is formed by punching out a metal plate 5, in which a plurality of conductors 3 are arranged in parallel and both ends of each conductor 3 are connected by connecting pieces 41, 41a.

At the same time as the above punching process or in a subsequent process, a groove part 31 is formed by press work in order to facilitate connection of one end of each conductor 3 to a mating member (not shown).

The connecting piece 41a of the conductive member 4 on the side far from the groove 31 is cut.

As shown in FIG. 3, the cut end of each conductor 3 is fitted between the caulking pieces 21, 21 of the terminal 2, and fixed by caulking by press working.

Each terminal 2 is inserted into the case 1 without separating the other connecting piece 41. Since the plurality of terminals 2 can be aligned through the conductive member 4,
It is possible to automate the insertion work of the terminal 2.

Through the above operations, the connector shown in FIG. 1 is constructed. When connecting the connector to the mating member,
The remaining connecting piece 41 can be cut off and connected to each conductor 3.

FIG. 5B shows another embodiment of the present invention, in which two conductive members 4, 4a are formed by connecting the conductors 3, 3a alternately with different connecting pieces 41, 41, and each conductor 3, , 3a are fitted into each other between the mating conductors, and were formed by punching a metal plate 5. The material yield for forming conductors is further improved.
