Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0029] Example 1

[0030] Reference Figure 1 and Figure 2 , which is the first embodiment of the present invention, provides a portable electric energy metering device communication module tester, which includes a tester component 100 and a protection component 200. The protection component 200 provides better protection for the tester component 100, thereby improving its safety and convenience in carrying.

[0031] Specifically, the tester assembly 100 includes a tester body 101, a liquid crystal touch screen 102, a module socket 103 and a high-voltage interface 104. The liquid crystal touch screen 102 is arranged on the tester body 101. A test cavity S is opened on the tester body 101. The module socket 103 is located in the test cavity S. The high-voltage interface 104 is arranged on the top of the tester body 101.

[0032] The protective component 200 is arranged on both sides of the tester body 101, and includes a protective plate 201, a buckle 202, a movable plate 203, a connector 204, a placement ring 205, an interface line 206, a winding piece 207, a limiter 208 and a conductive piece 209. The protective plate 201 is fixed to one side of the tester body 101 through the buckle 202, the movable plate 203 slides on the other side of the tester body 101, the connector 204 is fixed on both sides of the connector 204, the placement ring 205 is fixed to one side of the tester body 101 and is located in the movable plate 203, the interface line 206 is arranged in the placement ring 205 through the winding piece 207, the limiter 208 is arranged on one side of the movable plate 203, and the conductive piece 209 is arranged on the winding piece 207.

[0033] The protective plate 201 is rectangular, and two rectangular protrusions are fixed on one side close to the tester body 101. When it is placed on the tester body 101, the two rectangular protrusions will be inserted into the test cavity S accordingly, thereby protecting the test cavity S and preventing dust and other foreign matter from entering the test cavity S during storage and transportation, which will have a great impact on subsequent tests. Two buckles 202 are provided, which are respectively fixed on the top and bottom of one side of the tester body 101. They are made of flexible material to facilitate the disassembly and assembly of the protective plate 201. The movable plate 203 is U-shaped and slides on the back of the tester body 101 through the connecting piece 204. The side away from the tester body 101 can be fixed with belts and other equipment that are convenient for staff to hold the tester, which is not shown in the figure.

[0034] The placement ring 205 is located on the inner side of the movable plate 203, and two interface lines 206 are provided, which are wound together on the winding piece 207. The limiting piece 208 is used to limit the winding piece 207. When in use, the limiting effect of the limiting piece 208 makes the winding piece 207 can only rotate in one direction, so as to facilitate the use of the interface line 206. The conductive piece 209 is used to electrically connect the interface line 206 with the high-voltage interface 104, so as to use the interface line 206 to test the module, and there is no need to carry the interface line 206 additionally, which greatly improves the portability of the tester.

[0035] Example 2

[0036] Reference Figure 2 to Figure 8 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0037] Specifically, the connecting member 204 includes a connecting plate 204a, a guide block 204b and a clamping plate 204c. The connecting plate 204a is fixed to the top and bottom of both sides of the movable plate 203, the guide block 204b is fixed to both sides of the tester body 101, a guide hole K is opened in the middle of the connecting plate 204a, the guide block 204b slides in the guide hole K, and the clamping plate 204c is fixed to both sides of the protective plate 201 and cooperates with the connecting plate 204a.

[0038] There are four connecting plates 204a, which are symmetrically fixed on the top and bottom of both sides of the movable plate 203. A limiting block is fixed at the end of the guide block 204b to prevent it from escaping from the guide hole K. A movable groove is opened on the inner side of the card plate 204c. When installing the protective plate 201, the card plate 204c is inserted into the connecting piece 204 so that the connecting piece 204 is in the movable groove, which can guide and limit the protective plate 201 and improve its installation efficiency. At the same time, during the installation process, the card plate 204c will push the connecting plate 204a and the movable plate 203 to move a certain distance to reset the interface line 206.

[0039] The connecting member 204 further includes a first spring 204d, two ends of which are respectively fixed to the inner wall of the movable plate 203 and the tester body 101.

[0040] The first spring 204d applies a force to the movable plate 203 to move toward the tester body 101, so that the movable plate 203 can be reset more conveniently after the protective plate 201 is removed. At least four of the first springs 204d are symmetrically installed at the four inner corners of the movable plate 203 so that the movable plate 203 can be evenly stressed.

[0041] The winding member 207 includes a winding post 207a, a ratchet 207b, a rotating block 207c, a fixed shaft 207d and a stopper 207e. The winding post 207a is rotatably connected to the inner side of the placement ring 205, and a groove P is opened at its end. The ratchet 207b is fixed in the groove P, and the rotating block 207c is located on one side of the ratchet 207b. The fixed shaft 207d slides in the rotating block 207c, and the stopper 207e is fixed to the inner wall of the groove P and is located on one side of the rotating block 207c.

[0042] The winding post 207a is rotatably connected to the back of the tester body 101 via a bearing. The setting of the rotating block 207c and the ratchet 207b makes it possible for the winding post 207a to only rotate in one direction in the initial state, which is convenient for pulling out the interface line 206 for wiring operations. A torsion spring is installed at the connection position between the winding post 207a and the tester body 101, which can facilitate the reversal of the winding post 207a and wind the interface line 206 around the surface of the winding post 207a. This part is not shown in the figure and can be set as needed by technicians in this field.

[0043] The rotating block 207c slides on the surface of the fixed shaft 207d, and a limit block is fixed at the end of the fixed shaft 207d to prevent the rotating block 207c from detaching from its surface. The stop block 207e is used to block one side of the rotating block 207c so that it can only rotate in one direction. A torsion spring is provided between the rotating block 207c and the fixed shaft 207d to reset the rotating block 207c. This part is not shown in the figure and can be set as needed by technicians in this field.

[0044] The winding member 207 further includes a baffle 207 f , which is located at the end of the winding post 207 a and inside the placement ring 205 .

[0045] The baffle plate 207f is annular and is used to limit the interface line 206 to prevent it from escaping from the placement ring 205. The baffle plate 207f is rotatably connected to the winding column 207a via a bearing.

[0046] The limiting member 208 includes a fixed plate 208a, a connecting rod 208b, a handle 208c and a second spring 208d. A rectangular groove Y is opened on the baffle 207f. The fixed plate 208a is fixed in the rectangular groove Y. The fixed shaft 207d slides in the fixed plate 208a and is fixed to the connecting rod 208b. The handle 208c is fixed to the end of the connecting rod 208b and is located on the outside of the movable plate 203. The two ends of the second spring 208d are respectively fixed to the rotating block 207c and the fixed plate 208a.

[0047] The fixed plate 208a is rectangular. When the staff needs to reset the interface line 206 and wind it on the winding post 207a, the handle 208c and the connecting rod 208b can be manually pulled away from the movable plate 203, thereby driving the fixed shaft 207d and the rotating block 207c to move, so that the rotating block 207c is disengaged from the ratchet 207b. At this time, the winding post 207a loses the limiting effect of the rotating block 207c and the ratchet 207b, and starts to reset and reverse, and wind the interface line 206 on the winding post 207a. When the staff releases the handle 208c, the rotating block 207c is pulled back to cooperate with the ratchet 207b through the second spring 208d, which is convenient for subsequent use.

[0048] At the same time, when installing the protective plate 201, the card plate 204c is inserted into the connecting piece 204 so that the connecting piece 204 is in the movable groove. The card plate 204c will push the connecting plate 204a and the movable plate 203 to move a certain distance. The handle 208c and the connecting rod 208b can be driven to move through the movable plate 203, and the interface line 206 is reset without the need for the staff to perform additional reset operations, thereby further improving the convenience of operation.

[0049] The limiting member 208 further includes a limiting frame 208e, which is fixed to the outside of the movable plate 203 and is located on both sides of the handle 208c, and cooperates with the handle 208c.

[0050] There are two limit frames 208e with opening directions opposite to each other, so that the handle 208c can be stuck in the two limit frames 208e when rotating, thereby fixing the handle 208c to prevent it from accidentally moving during use, which would cause great inconvenience to the testing process.

[0051] The conductive member 209 includes a conductive column 209a, a first conductive rod 209c, a second conductive rod 209d and an adapter 209e. The conductive column 209a is fixed to one side of the tester body 101 and is rotatably connected to the winding column 207a. The first conductive rod 209c and the second conductive rod 209d are fixed to the end of the conductive column 209a and are fixed to the baffle 207f. The adapter 209e is fixed to the top of the two conductive rods.

[0052] An insulating film is provided between the two conductive rods to prevent the two from contacting each other. The conductive column 209a is cylindrical and is fixed to the tester body 101 so as not to hinder its use when the winding column 207a rotates. Two connectors are fixed on both sides of the winding column 207a for fixing the interface line 206. Both connectors are in contact with the conductive column 209a and are electrically connected so as to maintain the electrical connection of the interface line 206 when the interface line 206 and the winding column 207a rotate. Two adapters 209e are provided and are respectively fixed to the top ends of the two conductive rods. The two conductive rods divide the conductive column 209a and the interface line 206 into positive and negative interfaces for subsequent testing. The working principle of this electrical connection is a prior art technology and is clearly known to those skilled in the art and will not be elaborated herein.

[0053] The conductive member 209 further includes a storage box 209f and a strong current connector 209g. The storage box 209f is fixed to one side of the tester body 101. The strong current connector 209g is located in the storage box 209f, and an end thereof is fixed to the adapter 209e.

[0054] Through holes V are formed at the top and bottom of the placement ring 205 .

[0055] The storage box 209f is used to store excess wires at one end of the high-voltage connector 209g to prevent too many wires from being exposed to the outside and affecting the convenience of carrying. There are two high-voltage connectors 209g, one end of which is fixed on two adapters 209e respectively, and the other end is used to be plugged into the high-voltage interface 104 to facilitate subsequent testing operations.

[0056] When in use, the tester is easy to store and carry, and can be carried without an additional suitcase. At the same time, the safety and protection are better during the carrying process, and there is no need to carry an additional interface line 206, which greatly improves the efficiency of the staff's testing operations. After use, it is more convenient to store, further improving the convenience of the staff to carry.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should be included in the scope of the claims of the present invention.
