Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to one connector provided on the case side and the other connector connected to a terminal portion of a cable by screw fastening, and at the same time, heat inside the case is exposed to the outside air. The present invention relates to a heat radiation type connector having a function of radiating heat.

[0002]

2. Description of the Related Art In general, an electronic device has a built-in device that generates heat, and each device is often arranged at a high density in order to miniaturize the electronic device. In addition, electronic device cases tend to consist of plastic moldings rather than metallic materials.

[0003]

The conventional electronic devices include the following:
As described above, there is a bad condition for the heat generated inside to be efficiently dissipated to the outside air. Efficiently radiating heat generation to the outside air is an essential condition for maintaining and improving the quality and performance of electronic devices. For this reason, a method of attaching a heat radiation fan and forcibly cooling air is adopted. Since this method hinders the downsizing of electronic devices, it cannot be adopted in many cases. In particular, in electronic devices that are focused on miniaturization, there is no choice but to adopt the natural heat dissipation (natural air cooling) method, and therefore it is required to devise efficient heat dissipation from all points of view. Therefore, we paid attention to a connector that is always provided in most electronic devices, and wondered if it could be used as a heat dissipation means.

The problem to be solved by the present invention is to solve the above problems of the prior art and to have a function of radiating the heat inside the case to the outside air, which can contribute to the lowering of the temperature inside the case. Type connector.

[0005]

According to the present invention, one pair of connectors provided on the case side and the other connector connected to the terminal portion of the cable are coupled by screw fastening, and the inside of the case is also provided. , Which has a function of radiating the heat of the outside air to the outside of the case, is attached to the case side connector, and is a heat receiving body of a heat conductive material having fins and screw holes for fastening; and is attached to the cable side connector and has cooling fins And a fastening screw body made of a heat conductive material. Here, it is preferable that the cooling fins are discs coaxially arranged side by side on the outside air side portion of the screw body.

[0006]

According to the present invention, the heat generated inside the case is received (collected) by the fins of the heat receiving body, is conducted to the screw body through the heat receiving body and the screw holes for fastening, and the cooling fins of the screw body are The heat is radiated to the outside air having a lower temperature than the inside of the case.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a heat dissipation type connector according to the present invention will be described below with reference to FIG. In FIG. 1, a case 1 houses an electronic device main body, and a pair of connectors 2 (for example, plugs) are attached to the right outer wall thereof. The mounting adapter 3 is a metal (heat conductive) standard accessory member added to each mounting portion at both ends of the connector 2, and is selected according to how the connector 2 is mounted on the case 1. The mounting adapter 3 is provided with a screw hole 3a in which a fastening screw 8 described later is screwed, and a screw hole for a machine screw 5 is formed at a right angle to the screw hole 3a in parallel with the axial direction of the plug of the connector 2. Further, the heat-receiving metal fitting 4 is a member in which a heat-receiving fin 4a having a multi-mountain shape and a large surface area is integrally formed with band-shaped portions which are not connected to the upper and lower end portions and which are connected to each other, respectively. Then, it is fixed to the mounting adapter 3 with a small screw 5. The connector 6 shown on the right side of FIG. 1 removed from the connector 2 on the case 1 side is attached to the tip of the cable 7. The fastening screw 8 attached to the connector 6 side for fastening the respective connectors 2 and 6 is configured as a cervical head screw that does not come off even if the screw is loosened. The disk-shaped cooling fins 8a are arranged in parallel on the portion exposed to the outside air).

Therefore, the heat generated inside the case 1 is received by the heat receiving fins 4a of the heat receiving metal fitting 4, is conducted to the fastening screw 8 through the heat receiving metal fitting 4 and the fastening screw hole 3a, and further the fastening screw 8's. The heat is radiated to the outside air through the cooling fins 8a. The heat radiated by the cooling fins 8a may be natural heat radiated or may be based on a forced airflow by a fan (because installing the fan outside the case 1 is not directly related to miniaturization of the electronic device). ). There is no forced airflow at the heat receiving fins 4a inside the case 1 (because a fan cannot be installed because the electronic device is downsized). As a result, the internal temperature of the case 1 is reduced by the pair of the connectors 2 and 7, which helps maintain and improve the quality and performance of the electronic device. In addition, since each pair of connectors 2 and 7 is used in most electronic devices and has a simple heat dissipation structure, it has a wide range of application.

[0009]

According to the present invention, the following excellent effects can be expected. (1) The heat generated inside the case is received by the fins of the heat receiving body, radiated to the screw body through the screw holes, and further to the outside air from the cooling fins of the screw body. Therefore, the connector can contribute to the lowering of the temperature inside the case, which in turn helps maintain and improve the quality and performance of the electronic device. (2) Since the connector is always used in the device and the heat dissipation structure is simple, its application range is wide.
