The electronic element 7 is mounted and connected. Further, the bent portion is formed by folding back in multiple stages, and an electronic element is mounted and connected for each bent portion.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an electronic element multilayer built-in connector in which electronic elements such as diodes are arranged in multiple layers on a circuit board by utilizing bent portions of lead terminals.

[0002]

[Prior art]

 FIG. 7 shows a conventional connector with a built-in electronic element. The electronic element built-in connector 20 is configured such that a plurality of electronic elements 3 such as diodes are solder-connected to a substantially parallel printed circuit 2 formed on the circuit board 1 to connect the respective circuits 2 in parallel, and at the same time, the respective circuits 2 are connected. The bases of the lead terminals 21 are soldered to the terminals 2a, and the circuit board 1, the electronic element 3, and the bases of the lead terminals 21 are molded with a resin material 9.

If the electronic element 3 is a diode, it can perform such functions as rectifying the current from the lead terminal 21 in one direction and obtaining a bias having better characteristics than a resistor circuit (not shown). However, in the above-described conventional structure, when the number of circuits 2 is increased and the number of electronic elements 3 is increased, the connector 20 itself is enlarged in the lateral direction, which necessitates a large amount of mounting area. There was a problem that it could not be stored in a small space such as.

[0004]

[Problems to be solved by the device]

 In view of the above points, the present invention is an electronic device that can be easily stored in a space of a small mounting area such as a vehicle without lateral enlargement of the connector itself when the number of circuits is increased and the number of electronic elements is increased. An object is to provide a connector with a built-in element.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides an electronic element built-in connector in which an electronic element and a lead terminal are connected on a circuit board, and a bent portion is formed at the base of the lead terminal so as to face the electronic element. The basic structure is that another electronic element is mounted and connected on the bent portion. A structure in which the bent portions are folded back in multiple stages and an electronic element is placed and connected for each bent portion is also possible.

[0006]

[Action]

 Electronic elements are arranged and connected in multiple layers in the height direction on the bent portion formed on the lead terminal base on the circuit board. As a result, the connector itself is prevented from expanding laterally and can be stored in a space with a small mounting area.

【Example】

 1 to 3 show a first embodiment of a connector with a built-in electronic element according to the present invention. FIG. 1 shows a conventional circuit board 1, a first electronic element 3 such as a diode connected to a printed circuit 2 on the board 1, and a lead terminal 4 connected to a terminal of the circuit 2. The lead terminal 4 has a bent portion 5 which is bent upward by one step at the base, and the middle portion 6 of the lead terminal 2 in a state where the bent portion 5 faces the first electronic element 3 as shown in FIGS. Is soldered to the terminal 2a of the circuit 2.

A second electronic element 7 is further soldered on the bent portion 5. The second electronic element 7 has its both ends 8, 8 mounted and connected on the adjacent lead terminals 4 to connect the lead terminals 4 in parallel. Further, the circuit board 1, the electronic elements 3 and 7, and the base portion of the lead terminal 4 are molded with the resin material 9.

When soldering the second electronic element 7, it is preferable to use solder having a melting point lower than that of the first electronic element 3. Also, solder connection by spot is possible. It is also possible to solder the bent portion 5 of the lead terminal 4 directly to the first electronic element 3. With the above structure, various electronic device circuits can be obtained.

4 to 6 show a second embodiment of the electronic element multilayer built-in connector according to the present invention. In this structure, the base portion of the lead terminal 4 in the first embodiment is folded back and extended as shown in FIG. 5, and the third electronic element 11 is further soldered on the folded back portion 10. That is, the first electronic element 3 is soldered onto the printed circuit 2 of the circuit board 1, and the second electronic element 7 is connected to the first bent portion 15 of the lead terminal 14 so as to face the first electronic element 3. Is mounted and connected, and the third electronic element 11 is mounted and connected to the second folded and bent portion 10.

The bent portions 10 and 15 of the lead terminal 14 can be formed in multiple stages without being limited to two stages, which allows a more complicated electronic element circuit to be formed than in the first embodiment. Finally, the resin material 16 is molded and completed.

[0012]

[Effect of device]

 As described above, according to the present invention, since the electronic elements can be arranged and connected in multiple layers on the bent portion formed on the lead terminal base portion on the circuit board, the connector itself can be complicated without lateral enlargement. In addition, various electronic element circuits can be obtained, and the electronic element circuit can be easily assembled in a small mounting area such as a vehicle.
