Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a connector for electrically connecting with a circuit board on which electronic components are arranged, and in particular, a connector that is partially equipped with circuit components such as semiconductor chips. Regarding connectors.

[Conventional technology]

Conventionally, connectors have been used to electrically connect a circuit board on which electronic components are arranged and an external circuit. For example, a female connector is attached to a circuit board, a male connector is connected to an external circuit, and the male and female connectors are fitted together to establish an electrical connection. In a structure using this connector, the circuit board can be easily replaced by simply removing and fitting the connector.

In addition, as an improvement on such a connector, as described in Japanese Patent Application Nos. 57-6385, a female connector is attached to a circuit board in which electronic components are assembled on a printed wiring board. A connector housing is provided which fits into the connector housing and an electrical contact pin is inserted and supported therein, and the electrical contact pin is inserted into and connected to the female connector on one side and connected to a bank wiring board connected to an external circuit on the other hand. There have also been proposals that provide electrical connection between the circuit board and an external circuit.

[Problem that the invention seeks to solve]

By the way, in a situation where the number of system LSIs has increased in recent years and the contents of EPROMs, etc. need to be changed frequently due to requests for functional expansion, etc., it is necessary to temporarily remove or replace the circuit board. Therefore, the opportunities for connecting and disconnecting connectors are increasing. Of course, if a failure occurs in some of the electronic components, it will be necessary to replace the circuit board.

However, with conventional circuit boards, the required electronic components are mounted on the printed wiring board to configure the required circuit, so especially when replacing the circuit board, electronic components that do not require replacement are also included in the circuit. It is necessary to replace the circuit board together with the board, and the cost of preparing the circuit board and the electronic components mounted thereon to be replaced becomes expensive, which is economically undesirable.

Furthermore, printed wiring boards are equipped with all necessary electronic parts, including electronic parts that rarely require replacement, which is an obstacle in reducing the size of circuit boards.

[Means for solving problems]

In view of the above problems, the connector of the present invention makes it possible to reduce the number of electronic components mounted on a circuit board, thereby reducing the size of the circuit board and reducing the cost of the circuit board for replacement personnel. It is.

The connector of the present invention is configured such that an electronic component is mounted in a housing of the connector, and the mounted electronic component can be electrically connected to a circuit board or an external circuit through a conductive path provided in the housing.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is an exploded perspective view of an embodiment of the present invention, and FIG. 2 is a sectional view showing the fitted state. Here, various electronic components 5 are mounted on a printed wiring board 4. An example is shown in which a circuit board 1 and a back wiring board 2 connected to an external circuit are electrically connected by a connector.

That is, the connector is a female connector 1 attached to a circuit board 1.
0 and a male connector 2o that fits therein, and the male connector 2o is configured to be electrically connectable to the back wiring board 2 as well.

The female connector 10 has a housing 11 with a plurality of fitting holes 12, and each of the fitting holes 12 has a female contact 14 connected to the wiring of the circuit board 1 through a lead wire 13. ing.

The male connector 20 has a housing 2 that includes a guide wall 22 that fits into the housing 11 of the female connector 10.
1, and this housing 21 has a plurality of contact bottles 2.
3 is inserted and supported. These contact pins 23 can electrically contact the female contacts 14 by fitting their rear ends into the fitting holes 12 of the female connector 10. Further, the front end of the contact pin 23 is connected to the back wiring board 2.
It can be fitted into the plurality of insertion holes 3 and electrically contacted thereto.

Further, the male connector 20 is shown in a plan view in FIG.
As shown in the vertical cross-sectional views in the figures, contact pins 23 are inserted into and supported through a plurality of insertion holes 24 formed in the housing 21 made of insulating resin. The conductor path 2 is formed by selectively disposing conductive resin.
5 is formed. A part of the conductor path 25 is formed on the inner surface of the insertion hole 24 to be electrically connected to the contact pin 23, and the other part of the conductor path 25 is formed on the inner surface of the insertion hole 24.
The recesses 26 provided at other locations are formed as desired. A semiconductor chip or other electronic component 27 is mounted in this recess 26 and electrically connected to the conductor path 25 by a metal wire 28 or the like. Although the semiconductor chip and other electronic components 27 are originally mounted on the circuit board 1, they do not need to be replaced when the circuit board 1 is replaced.

Therefore, according to this configuration, the circuit board 1 and the bank wiring board 2 have the contact pins 23 of the male connector 20 connected to the female contacts 14 of the female connector 10 at the rear end, as shown in FIG. The electrical connection is made by fitting the front end into the insertion hole 3 of the back wiring board 2. When the circuit board 1 is once removed or replaced with another circuit board, the contact pins 23 of the male connector 20 need only be removed from the female connector 10, and this can be done in the same manner as before.

However, in this configuration, the housing 21 of the male connector 20 has a required circuit formed by the conductor path 25 and the electronic component 27, and this circuit is a part of the circuit of the circuit board 1, in this case the circuit board. Since the circuit board 1 is configured as a circuit that does not require replacement even when the circuit board 1 is replaced, the circuit configured by the circuit board 1 can be omitted and the number of electronic components to be mounted can be reduced accordingly.

Therefore, the circuit board can be made smaller, which is advantageous in terms of space.

In addition, by mounting some of the electronic components originally mounted on the circuit board 1 in the housing 21, it is possible to simplify the configuration of the circuit board as a replacement personnel when replacing the circuit board 1. It is possible to reduce the number of electronic components mounted on the device, making it economically advantageous.

The conductor path 25 may be formed of a conductor film 25a formed by printing, plating, or the like over the surface of the housing 21 or the inner surface of the insertion hole 24, as shown in FIG.

Furthermore, as shown in FIGS. 6(a) to 6(d), the contact pin 23 is a breath-fit pin in which easily deformable fitting parts 23a and 23b having different width dimensions are formed in a part of the front end. May be adopted. As shown in FIG. 7, this contact pin has a wide fitting part 23a inserted into the insertion hole 24 of the male housing 21, and a small fitting part 23b inserted into the insertion hole 3 of the back wiring board 2. It may be inserted. According to this, the strength of the insertion support of the contact pin 23 can be improved, and the electrical contact efficiency can be improved. Moreover, the operability of inserting the contact pin 23 can also be improved.

Note that in the contact pins shown in FIGS. 6(C) and 6(d), the fitting portions 23a and 23b are each formed into a tapered shape to further improve insertion performance and contact performance.

〔Effect of the invention〕

As explained above, the present invention mounts an electronic component in a housing of a connector, electrically connects the mounted electronic component to a contact pin of the connector through a conductor path provided in the housing, and connects the electronic component to a circuit board via the contact pin. Since the connector is configured to be electrically connected to external circuits, part of the circuit on the circuit board can be configured with the circuit in the connector, reducing the number of electronic components mounted on the circuit board, reducing the size of the circuit board, or It is possible to implement high-density mounting of circuit boards, and also to reduce the cost of circuit boards that require replacement, thereby solving economic problems.
