Description

[Detailed Description of the Invention] The present invention relates to a connector housing for a circuit board used, for example, in a harness circuit of an automobile.

In automobile harness circuits, electronic circuit elements such as diodes and resistors are sometimes inserted, and these circuit elements can be mounted using a number of methods similar to those disclosed in Japanese Utility Model Application Publication No. 53-47593. This method is known.

For example, as shown in FIGS. 1a and 1b, the method of molding an element 1 and inserting it with terminals 2 is a relatively new method.

In the case of Fig. 1a, the molded part 4 is formed around the element 1 after the terminal 2 with which the element 1 is crimped and connected is inserted into the housing 3, and in the case of Fig. 1b, the element 1 is crimped and connected with the terminal 2. A mold portion 4 is later formed on the element 1.

Since these have a molded portion 4 and the like, they are effective from the standpoint of protecting the element 1 from external impact, but there are problems such as loosening of the element lead wire crimp connection portion of the terminal 2 due to mechanical vibration or the like.

Furthermore, when an excessive current flows and the element 1 generates heat, its molded portion is likely to be thermally burnt out, and surrounding harnesses and other equipment may also catch fire.

Furthermore, it is impossible to visually confirm the element 1 which has become defective due to these causes, and the discovery of the cause of the failure tends to be delayed.

In order to solve this problem, a circuit board 12 with circuit elements 10 mounted on an insulating board 11 as shown in FIG. 2 is housed in a female housing 30 and a male housing 31 as shown in FIG. It is conceivable to protect it from impact and to provide a cavity around it.

The purpose of the present invention is to provide a connector housing for a circuit board for protecting and securely holding the circuit board, which consists of a female housing and a male housing that can be combined, each with a circuit board. It has a built-in receiving terminal with electric wire for connection to the insertion connection end of the board, and when combined, an internal cavity is formed for storing the circuit board, and at least one of the female housing and the male housing has a circuit board. It is characterized by forming a guide structure for guiding and supporting the.

As shown in FIG. 2, the circuit board 12 is mainly composed of, for example, an approximately cross-shaped insulating board 11, and both ends of its short shaft portion are insertion connecting portions 13 and 14.

Electronic circuit elements 10 such as diodes, resistors, light emitting diodes, capacitors, coils, and ICs are fixed to the front side of the long axis portion of the insulating substrate 1111 with, for example, solder, with the longitudinal direction thereof aligned with the direction of the long axis portion. The lead ends 15.16 at both ends are conductor parts 17. cut out from the metal foil stretched on the back side of the connection ends 13.14. 18 are electrically connected via conductive parts 19 and 20, which are also cut out from the metal foil.

The female housing 30 and male housing 31 that house the circuit board 12 have a structure as shown in FIG. 3, for example.
They are designed to be able to fit into each other and be combined, and have a cavity 32 in which the circuit board 12 can be accommodated inside the combined body.

A circuit board 1 is mounted on both sides of the cavity 32 of the female housing 30.
A circuit board guide groove 33. into which the ends 21.22 of 2 can be inserted.
34 are provided.

Furthermore, each housing 30, 31 has a receiving terminal 35 for electrically connecting with the connecting ends 11, 12 of the circuit board 12.
．． 36 is built in, and is led out to the outside by electric wires 37, 38 connected to the receiving terminals 35, 36.

Note that 39 indicates a claw of the locking mechanism, and 40 indicates a receiver thereof.

Therefore, in order to accommodate the circuit board 12 in this connector housing, first the ends 21.22 of the circuit board 12 are fitted into the guide grooves 33.34 of the female housing 30 and pushed in, and then the connecting ends 14 are inserted into the sockets. It is inserted into the terminal 35.

Further, when the male housing 31 is fitted and pushed into the female housing 30, the connection end 13 of the circuit board 12 is inserted into the receiving terminal 36 of the male housing 31, and is locked by the claw 39 and the receiver 40. .

Thus, as shown in FIG.
0 will be electrically inserted between the electric wires 37 and 38.

The circuit board 12 is held by the receiving terminals 35, 36, which also serves as an electrical connection, and the presence of the guide grooves 33, 34 makes it more securely fixed to the housing. Connect the connection end 14 of the board 12 to the receiving terminal 3
5, the guide groove 33.
The connection between the connection terminal 14 and the receiving terminal 35 is automatically completed by simply sliding the terminal 34 inside the terminal 34, which is extremely convenient for maintenance work on automobiles, etc., which tends to be performed in dark areas.

In the embodiment, the circuit board 12 has a special shape, but it is not necessarily limited to this, and any shape can be selected within the scope of the utility model registration claim. The same applies to

As explained above, the circuit board connector housing according to the present invention replaces the conventional terminal structure mounting method with the circuit board method when inserting a circuit element into a harness circuit, etc. It is intended to protect the circuit board from impact, etc., and has the effect of reliably holding the circuit board and facilitating insertion of the circuit board.
