Description

Technical Field

[0001] The present invention relates to an electrical connector for supplying and maintaining mains power (signal). Background Art

[0002] Generally speaking, the semiconductor manufacturing process requires various utilities, such as air, nitrogen, vacuum, pure water (DW), power supply, etc. During the manufacturing process, it is very important to ensure the smooth supply of utilities.

[0003] For example, during the semiconductor device packaging process, testers and sorters are used to perform electrical inspections on the assembled unit semiconductor devices. The sorter receives electrical signals and performs mechanical actions to connect the semiconductor devices to contactors connected to the tester to inspect their electrical characteristics. Based on the inspection results, the semiconductor devices are classified as defective or non-defective. The semiconductor devices are then unloaded onto semiconductor packaging carriers such as tubes and trays.

DETAILED DESCRIPTION

[0016] The descriptions of certain structures or functions proposed in the embodiments of the present invention are merely intended to illustrate embodiments consistent with the concepts of the present invention. Embodiments consistent with the concepts of the present invention may be implemented in various forms. Furthermore, they should not be construed as being limited to the embodiments described in this specification, but rather should be understood to include all modifications, equivalents, or alternatives within the scope of the concept and technology of the present invention.

[0017] The present invention will be described in detail below with reference to the accompanying drawings.

[0018] Figure 1 and Figure 2 are perspective views respectively showing a disconnected state and a connected state of an electrical connector for utility supply according to an embodiment of the present invention, Figure 3 and Figure 4 Each of them is a perspective view showing only a terminal portion of an electrical connector for utility supply according to an embodiment of the present invention.

[0019] Reference Figures 1 to 4 , the electrical connector 1 for utility supply according to an embodiment of the present invention includes a first connecting member 110 , a first terminal portion 120 , a second connecting member 210 and a second terminal portion 220 .

[0020] The first connecting member 110 and the second connecting member 210 are respectively arranged at the utility supply end and the utility receiving end, and can include a male and female connection guide member. In this embodiment, the connection guide member shows a guide arm 111 protruding from the first connecting member 110 in the connection direction and a guide groove 211 formed on the second connecting member 210, wherein the guide groove 211 corresponds to the guide arm 111 and the guide arm 111 is inserted therein. Such a guide member can have various shapes within the scope of being able to connect the first connecting member 110 and the second connecting member 210. In addition, although not shown in the figure, a locking member can be additionally provided to mechanically lock or unlock the connection state of the first connecting member 110 and the second connecting member 210. Reference numeral 240 is a connector provided on the second connecting member for providing utility pneumatic power.

[0021] The first terminal portion 120 is a terminal provided on the first connecting member 110 for providing power to the utility receiving terminal. The first terminal portion 120 includes a terminal mold 121 fixed to the first connecting member 110 and a bar-type terminal block 122 fixed to the terminal mold 121.
