Description

Junction Box for Vehicle Having Test Pin of Tap Terminal Type}

The present invention relates to a junction box for a vehicle having a test pin member in the form of a tab terminal, and more particularly, by assembling the test pin member in the form of a tab terminal that can be manufactured in one mold instead of a conventional header pin on a printed circuit board. The present invention relates to a junction box for automobiles having a test pin member in the form of a tab terminal, which is capable of assembling, greatly reducing assembly time, preventing defects such as misassembly, and at the same time reducing mold manufacturing cost.

Automobiles are equipped with a number of electrical devices composed of fuses and relays. Such electric devices for automobiles can be classified into an electric device on the engine side and an electric device on the body. The electric devices on the engine side include an ignition device composed of an ignition coil, a distributor high voltage cable, a spark plug, and a charging device composed of a generator and a regulator. In addition, the vehicle body-side electric devices include lighting devices including lighting batteries, lighting devices for signs, signals, instrument warning signs provided in the instrument panel, and cooling and heating devices.

These automotive electrical devices are each connected to an ECU (Electronic Control Unit) via a wire, and a junction box is used as an intermediate medium for connecting the wire and the ECU to each other.

The junction box is for performing a function for transmitting power and control signals to the vehicle electrical apparatus. The junction box is usually mounted in an engine room and a vehicle interior, and a plurality of fuses, relays, and electronic components are disposed in the box. do.

The structure of the junction box can be broadly divided into a printed circuit board, and a top and bottom cases finishing the upper and lower parts of the printed circuit board.

A plurality of fuses and relays are assembled to the printed circuit board. However, once the relay is assembled on the printed circuit board it is very difficult to determine whether the failure.

Accordingly, in order to test whether the relay is operated, test pins are assembled in advance on the printed circuit board, and the printed circuit board and the inspection apparatus are electrically connected to each other to check the operation.

In other words, by operating the relay assembled on the printed circuit board so that the signal of the relay is transmitted to the connector terminal through the test pin, and by measuring the current through the current meter of the inspection device to check whether the relay is defective.

One example of a header pin being used for testing the relay is shown in FIG. 1.

The conventional header pin shown in FIG. 1 includes a header portion 12 having a substantially rectangular shape and a pin portion 15 inserted into a coupling hole 12a provided in the header portion 12.

However, the conventional header pin has a problem in that the mold manufacturing cost is increased because the mold of the header portion 12 and the mold of the pin portion 15 must be manufactured separately.

In addition, the conventional header pin has a problem in that the pin 15 is manually inserted and assembled into the coupling hole 12a of the header 12.

In addition, in the conventional header pin, since the pin portion 15 cannot be automatically inserted into the printed circuit board even after the pin portion 15 is coupled to the header portion 12, the header pin must be manually inserted into the printed circuit board. There is a problem.

For this reason, the conventional header pins require a lot of assembly time and have a high incidence of assembly failure.

In addition, because the pin is thin, there is a limit to the amount of current that can be delivered, there is a problem that can not be used for large relay check.

In addition, since the structure of the pin is limited in the amount of current that can be delivered, there is a problem that the design constraints when designing the header pin.

The present invention is proposed in order to solve the above problems of the prior art, by manufacturing a test pin member in the form of a tab terminal that can be produced in one mold and assembled to a printed circuit board, a tab that can significantly reduce the manufacturing cost It is an object of the present invention to provide a junction box for a vehicle having a test pin member in the form of a terminal.

Another object of the present invention is to improve the conventional header pin structure to manufacture a test pin member in the form of a tab terminal that can be automatically assembled to a printed circuit board, thereby significantly reducing the assembly time and prevent the occurrence of incorrect assembly. The present invention provides a junction box for a vehicle having a test pin pin body in the form of a tab terminal.

It is still another object of the present invention to provide a junction box for automobiles having a tab pin type test pin member that can be applied to current measurement of a large-capacity relay and can improve design freedom.

The present invention for achieving the above object, in the junction box for a vehicle comprising a printed circuit board disposed between the upper, lower cases and a plurality of connection terminals are coupled through and formed at least one assembly hole, And a test pin member in the form of a tab terminal inserted into an assembly hole of the printed circuit board and fixed to the printed circuit board through a fixing means to electrically connect the inspection device of the relay and the printed circuit board. .

The fixing means is characterized in that to integrate the test pin member and the printed circuit board by soldering.

The test pin member may include a terminal portion inserted into the assembly hole and a stopper portion extending horizontally above the terminal portion so as to interfere with an upper edge portion of the assembly hole.

According to the present invention, since only one terminal mold needs to be manufactured without the need to separately manufacture the mold of the header and the mold of the pin, as in the conventional header pin, the manufacturing cost of the test pin member is greatly reduced.

In addition, by improving the structure of the conventional header pin, which is impossible to automatically assemble due to the structure of the pin, by forming the structure of the test pin member in the form of a tab terminal, it is possible to automatically assemble as in the case of general terminals, thereby significantly reducing the assembly time. And, there is an effect that can prevent the occurrence of misassembly due to manual assembly at its source.

In addition, it can be applied to the current measurement of a large capacity relay, and because of the large amount of current delivered due to the structural characteristics, there is an effect that can greatly improve the design freedom.
