Description

[Technical Field]

[0001] The present invention relates to electrical connectors for the supply and maintenance of utility power (signals). [Background technology]

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

[0003] For example, in the packaging process of semiconductor devices, a tester and handler are used to electrically test unit semiconductor devices after assembly is complete. The handler receives electrical signals and performs mechanical operations to connect the semiconductor devices to contactors connected to the tester, test their electrical characteristics, classify the semiconductor devices as defective or not based on the test results, and unload the semiconductor devices using semiconductor package carriers such as tubes and trays.

[0013] The specific structure or functional description presented in the embodiments of the present invention is merely exemplary for the purpose of describing the embodiments according to the inventive concept, and the embodiments according to the inventive concept can be embodied in various forms. Furthermore, it should not be construed as being limited to the embodiments described herein, but should be understood to include all modifications, equivalents, and alternatives within the spirit and technical scope of the present invention.

[0014] The present invention will now be described in detail with reference to the accompanying drawings.

[0015] Figures 1 and 2 are perspective views showing the separated and connected states of an electrical connector for utility supply according to an embodiment of the present invention, respectively, and Figures 3 and 4 are perspective views showing only the terminal portion of an electrical connector for utility supply according to an embodiment of the present invention.

[0016] 1 to 4, a utility supply electrical connector 1 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. As shown in FIG.

[0017] 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 a male-female coupling guide member. In this embodiment, the coupling guide member includes a guide arm 111 protruding from the first coupling member 110 in the coupling direction and a guide groove 211 recessed in the second coupling member 210 corresponding to the guide arm 111 and into which the guide arm 111 is inserted. Such a guide member may be modified into various shapes as long as the first coupling member 110 and the second coupling member 210 can be coupled. Meanwhile, although not shown, a separate locking member may be added to mechanically lock or unlock the coupled state of the first coupling member 110 and the second coupling member 210. Reference numeral 240 denotes a coupler provided in the second coupling member 210 to supply pneumatic utility.

[0018] The first terminal portion 120 is provided on the first coupling member 110 and is a terminal for supplying power to the utility receiving end, and may include a terminal mold 121 fixed to the first coupling member 110 and a bar-type terminal bar 122 fixed to the terminal mold 121. The terminal mold 121 may be made of a known insulating material for electrically insulating adjacent terminal bars.

[0019] In this embodiment, the terminal section indicates a power terminal unit for supplying power utilities and a signal terminal unit for inputting and outputting detection signals from sensors, and the first terminal section 120 and the second terminal section 220 each have two terminals and are used as DC power terminal units, but the power terminal unit may also be an AC power supply.

[0020] The signal terminal unit is arranged adjacent to the power terminal unit and is composed of a third terminal portion 130 provided on the first coupling member 110 and a fourth terminal portion 230 provided on the second coupling member 210. The only difference is the number of terminals; the first terminal portion 120 and the third terminal portion 130 are identical, and the second terminal portion 220 and the fourth terminal portion 230 are identical. In this embodiment, the fourth terminal portion 230 constituting the signal terminal unit is for the power supply of the sensor and includes two terminal plates 231 and four terminal plates 232 used for the sensor signals. The third terminal portion 130 is provided with the same number of terminal bars as the fourth terminal portion 230. The number of terminals in such a signal terminal unit can be increased or decreased.

[0021] As mentioned above, such a signal terminal unit is identical to a power terminal unit except for the number of terminals, so in the following, we will focus on the first terminal part 120 and the second terminal part 220 without distinguishing between the power terminal unit and the signal terminal unit.

[0022] Preferably, the third terminal unit 220 includes a housing 221 fixed to the second coupling member 210, a plate-shaped terminal plate 222 provided within the housing 221 so as to be movable 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 tip edge 222a at its tip that makes line contact with the terminal bar 122.

[0023] Figures 5(a) and (b) are cross-sectional diagrams showing the operating state of an electrical connector for utility supply according to an embodiment of the present invention, with (a) showing the separated state and (b) showing the connected state.

[0024] Referring to Figures 5(a) and 5(b), the first terminal portion 120 and the second terminal portion 220 come into contact with each other and are electrically connected by the coupling of the first coupling member 110 and the second coupling member 210. Specifically, the terminal plate 222 is elastically supported by the elastic body 223 and comes into contact with the terminal bar 121. The terminal plate 222 and the terminal bar 121 can maintain a stable contact state by elastically supporting the elastic body 223, which is compressed by a certain length d.

[0025] The present invention described above is not limited to the above-described embodiments and accompanying drawings, and it will be apparent to those skilled in the art to which the present invention pertains that various substitutions, modifications, and changes can be made without departing from the technical spirit of the present invention.
