In contrast, when an element is referred to as being "directly on" another element, there is no intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only."

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] See also Figure 1 and Figure 2 The present invention provides a handheld socket tester, including a main body 1 and a plug assembly 2. The plug assembly 2 includes a pin 21, a pin mounting bracket 22, and a pin fixing bracket 23. One end of the pin 21 is a socket contact piece 211, and the other end of the pin 21 is a clamping column 212. The pin mounting bracket 22 is provided with a socket 221 adapted to the clamping column 212, and the pin fixing bracket 23 is provided with a through hole 231 adapted to the socket contact piece 211. One end of the main body 1 is provided with an opening 11 adapted to the pin mounting bracket 22.

[0030] The pin mounting frame 22 is installed in the opening 11, the clamping column 212 of the pin 21 is plugged into the socket 221 of the pin mounting frame 22, and the socket contact piece 211 passes through the through hole 231 of the pin fixing frame 23. The pin fixing frame 23 is detachably fixed to the pin mounting frame 22;

[0031] The sockets 221 of the pin mounting frame 22 include multiple groups of sockets 221 corresponding to the posts 212 of various pin specifications.

[0032] In this embodiment, the pin mounting frame 22 can be integrally formed with the opening 1, or it can be separately formed and then bonded with an adhesive or snap-fitted with a snap-fit structure. When replacing a pin 21, the pin mounting frame 22 is removed using the corresponding disassembly method based on the connection method between the pin mounting frame 22 and the pin fixing frame 23, and the original pin is removed. The clamping column 212 of the new pin is then inserted into the insertion hole 22 of the pin mounting frame 22, and the pin fixing frame 23 corresponding to the new pin is fixedly connected to the pin mounting frame to complete the replacement of the different pins.

[0033] like Figure 3 As shown, the contact pieces 211 of the pins 21 are arranged in various configurations, and the corresponding latches 212 are also arranged in various configurations. Therefore, the pin mounting frame 22 is provided with multiple sets of sockets 221 to accommodate the replacement of pins of different specifications. Accordingly, the through holes 231 of the pin retaining frame 23 also vary accordingly. Therefore, when replacing pins of different specifications, the corresponding pin retaining frame 23 is also replaced.

[0034] Optionally, the pin specifications include three-phase line pins, and the three sockets 221 corresponding to the three-phase line pins are all in a teardrop shape. The teardrop shape can meet the requirements of various three-phase line pins for inserting the plugs into the sockets.

[0035] In some embodiments, as Figure 4 As shown, the pin mounting frame 22 is provided with a plurality of mounting holes 222 , and the pin fixing frame 23 is provided with a plurality of mounting posts 232 , and the mounting posts 232 are interference-connected with the mounting holes 222 .

[0036] In this embodiment, the diameter of the mounting post 232 is larger than the diameter of the mounting hole 222, and the mounting post 232 is deformable. When the mounting post 232 is inserted into the mounting hole 222, it is squeezed and deformed by the hole wall 222. Simultaneously, the deformation recovery force of the mounting post 232 acts on the hole wall, generating an interaction force between the mounting post 232 and the mounting hole 222. This allows the mounting post 232 to be detachably fixedly connected to the mounting hole 222, thereby achieving the installation and fixation of the pin 21.

[0037] In some embodiments, as Figure 5As shown, the pin mounting frame 22 is provided with a plurality of first mounting holes 223 , and the pin fixing frame 23 is provided with a plurality of second mounting holes 233 adapted to the first mounting holes 223 , and the first mounting holes 223 are connected to the second mounting holes 233 by bolts.

[0038] In this embodiment, a bolt is inserted into the second mounting hole 233 from the side of the pin holder 23 away from the pin mounting frame 23 and threaded into the first mounting hole 223, thereby bolting the first mounting hole 223 to the second mounting hole 233. Optionally, a groove is provided on the side of the pin holder 23 away from the pin mounting frame 23 to fit the bolt head. This allows the bolt head to be below the plane of the pin holder 23 after tightening, thereby ensuring that the side of the pin holder 23 away from the pin mounting frame is flat, thereby not affecting the insertion of the socket contact piece 211 into the socket.

[0039] In some embodiments, as Figure 6 As shown, the main body 1 is further provided with a circuit board 12 and a display screen 13. The circuit board 12 is electrically connected to the pins 21, and the display screen 13 is electrically connected to the circuit board 12. The main body 1 is also provided with a key 14, which is electrically connected to the circuit board 12. The circuit board 12 is used to execute the test program, the key 14 is used to control the test switch, and the display screen 13 is used to display test information.

[0040] In some embodiments, as Figure 6 As shown, the outer side of the main body 1 is provided with a concave pattern 16 to increase the friction with the user's hand, thereby facilitating the socket tester to be inserted into / pulled out of the socket.

[0041] In some embodiments, as Figure 6 As shown, the main body 1 is further provided with a battery compartment 15, which is arranged in the inner cavity of the main body 1 and is electrically connected to the circuit board 12. The battery compartment 15 has a built-in battery to power the circuit board 12 and the display screen 13.

[0042] In some embodiments, as Figure 7 As shown, the battery compartment 15 includes a battery compartment body 151 and a battery compartment cover 152. The compartment opening of the battery compartment body 151 is arranged on the outside of the main body 1, and the battery compartment cover 152 is detachably connected to the main body 1. The battery compartment cover 152 is provided to facilitate battery replacement.

[0043] In some embodiments, the battery compartment 15 is a battery compartment adapted for cylindrical batteries. Cylindrical batteries have large capacity, long cycle life, and a wide operating temperature range, which better meet the continuous power supply requirements of the socket tester.

[0044] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
