Description

Electrical connectors for utility supply

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

[0002] Typically, semiconductor manufacturing processes require various utilities such as air, nitrogen, vacuum, deionized water (DW), and power, and it is very important to ensure a smooth supply of utilities during the manufacturing process.

[0003] For example, in the semiconductor device packaging process, testers and handlers are used to electrically inspect individual semiconductor devices after assembly is complete. The handler receives electrical signals and performs mechanical movements to connect the semiconductor device to a contactor connected to the tester, thereby inspecting its electrical characteristics. Based on the inspection results, the handler classifies the semiconductor device as defective or defective and then unloads the semiconductor device onto a semiconductor package carrier, such as a tube or tray.

[0017] The specific structural and functional descriptions presented in the embodiments of the present invention are merely illustrative for the purpose of explaining embodiments according to the concept of the present invention, and embodiments according to the concept of the present invention may be implemented in various forms. Furthermore, they should not be construed as being limited to the embodiments described herein, but should be understood to include all modifications, equivalents, and substitutes included within the spirit and technical scope of the present invention.

[0018] Hereinafter, the present invention will be described in detail with reference to the attached drawings.

[0019] FIG. 1 and FIG. 2 are perspective views showing a separated state and a connected state of an electric connector for utility supply according to an embodiment of the present invention, respectively, and FIG. 3 and FIG. 4 are perspective views showing only a terminal portion of an electric connector for utility supply according to an embodiment of the present invention, respectively.

[0020] Referring to FIGS. 1 to 4, an electrical connector (1) for utility supply according to an embodiment of the present invention includes a first coupling member (110), a first terminal portion (120), a second coupling member (210), and a second terminal portion (220).

[0021] The first coupling member (110) and the second coupling member (210) are provided at the utility supply end and the utility receiving end, respectively, and may include male and female coupling guide members. In the present embodiment, the coupling guide member shows a guide arm (111) protruding in the coupling direction from the first coupling member (110), and a guide groove (211) formed in the second coupling member (210) corresponding to the guide arm (111) and into which the guide arm (111) is inserted. This guide member may be modified into various shapes within a range in which the first coupling member (110) and the second coupling member (210) can be coupled. Meanwhile, although not shown, a separate locking member that can mechanically fix or release the coupling state of the first coupling member (110) and the second coupling member (210) may be added. Drawing reference numeral 240 denotes a coupler provided in the second coupling member and through which a pneumatic utility is supplied.

[0022] The first terminal portion (120) is provided on the first connecting member (110) as a terminal for supplying power to a utility receiving terminal, and may include a terminal mold (121) fixed to the first connecting member (110) and a bar-type terminal bar (122) fixed to the terminal mold (121). The terminal mold (121) may be provided by a known insulating material for electrically insulating adjacent terminal bars.

[0023] In this embodiment, the terminal unit shows a power terminal unit for power utility supply and a signal terminal unit for input / output of detection signals of sensors, and the first terminal unit (120) and the second terminal unit (220) are each provided with two terminals and are shown to be used as DC power terminal units, and the power terminal unit may be an AC power source.

[0024] The signal terminal unit is arranged adjacent to and parallel to the power terminal unit, and is composed of a third terminal portion (130) provided in the first coupling member (110) and a fourth terminal portion (230) provided in the second coupling member (210). Only the numbers of terminals are different, and the first terminal portion (120) and the third terminal portion (130) are the same, and the second terminal portion (220) and the fourth terminal portion (230) are the same. In this embodiment, the fourth terminal portion (240) constituting the signal terminal unit shows two terminal plates (231) for the power of the sensor and four terminal plates (232) used for the signals of the sensor. The third terminal portion (130) is provided with terminal bars having the same number as the fourth terminal portion (240). The numbers of the terminals of this signal terminal unit may be increased or decreased.

[0025] Since these signal terminal units are identical to the power terminal units except for the number of terminals as described above, the following description will focus on the first terminal section (120) and the second terminal section (220) without distinguishing between the power terminal unit and the signal terminal unit.

[0026] Preferably, the third terminal portion (220) includes a housing (221) fixed to the second coupling member (210), a plate-shaped terminal plate (222) provided within the housing (221) to be able to move back and forth in the coupling direction of the first coupling member (110) and the second coupling member (210), and an elastic body that elastically supports the terminal plate (222) within the housing (221). Preferably, the terminal plate (222) includes a leading edge (222a) at the leading end that makes line contact with the terminal bar (122).

[0027] Figures 5 (a) and (b) are cross-sectional diagrams showing the operating state of an electric connector for utility supply according to an embodiment of the present invention, respectively, where (a) shows a separated state and (b) shows a connected state.

[0028] Referring to (a)(b) of FIG. 5, the first terminal portion (120) and the second terminal portion (220) are electrically connected by contacting each other as the first connecting member and the second connecting member are connected, and specifically, the terminal plate (222) is elastically supported by an elastic body (223) and is in contact with the terminal bar (121), and the terminal plate (222) and the terminal bar (121) are elastically supported by the elastic body (223) compressed by a certain length (d) so that a stable contact state can be maintained.

[0029] The present invention described above is not limited to the above-described embodiments and the attached drawings, and it will be apparent to a person skilled in the art to which the present invention pertains that various substitutions, modifications, and changes are possible within a scope that does not depart from the technical spirit of the present invention.
