[0002] The moving terminal block for electricity meters is a product that is already recognized in the international market. However, it is inconvenient to produce and operate. The traditional method of checking electricity meters using the moving terminal block is to fix them with screws. Existing moving terminal blocks may be prone to problems such as loose terminals and poor contact when affected by factors such as vibration and temperature changes, which will affect the normal operation of the equipment. Summary of the Invention

[0003] This utility model provides an automated current crimping block for mobile terminal tailstocks to solve the problems of loose terminals and poor contact that easily occur in mobile terminal tailstocks.

[0004] To achieve the above objectives, the present invention proposes an automated current crimping block for a mobile terminal tailstock, comprising a mounting base, an elastic element, a contact sheet metal, and a connecting element.

[0005] The contact sheet metal includes an interconnected mounting part and a contact part. The mounting base is provided with an interconnected first receiving groove and a second receiving groove. One end of the elastic member is installed in the first receiving groove, and the other end of the elastic member is located in the second receiving groove. The mounting part is installed in the second receiving groove, and the contact part is used to be inserted into the port of the electricity meter.

[0006] One end of the connector is connected to the mounting part. Pressing the other end of the connector can drive the mounting part to move in the second receiving groove along the first direction and squeeze the elastic member. The elastic member is used to provide elastic force so that the contact part abuts against the copper sheet of the port of the electricity meter.

[0007] Optionally, the mounting base is provided with a third receiving groove, which is located at the end of the second receiving groove away from the first receiving groove. The third receiving groove is in communication with the second receiving groove. One end of the connector passes through the third receiving groove and is connected to the contact sheet metal. The other end of the connector protrudes from the mounting base along the first direction.

[0008] Optionally, the first receiving groove extends along the first direction, and the second receiving groove penetrates the mounting base along the second direction; the first direction and the second direction are not parallel and do not coincide.

[0009] Optionally, it also includes a guide member and a guide sleeve, the guide member being connected to the contact sheet metal, the guide sleeve being mounted on the mounting base, and the guide member being inserted into the guide sleeve to guide the movement of the mounting part in the first direction.

[0010] Optionally, the mounting base is provided with a fourth receiving groove, which communicates with the second receiving groove. The guide sleeve is disposed in the fourth receiving groove, and the guide member is connected to the side surface of the contact sheet metal near the elastic member.

[0011] Optionally, the mounting base includes a first support plate and a second support plate connected to each other. The first support plate is provided with a first groove, a second groove, a third groove and a fourth groove, and the second support plate is provided with a fifth groove, a sixth groove, a seventh groove and an eighth groove.

[0012] The first groove and the fifth groove are connected to form the first receiving groove, the second groove and the sixth groove are connected to form the second receiving groove, the third groove and the seventh groove are connected to form the third receiving groove, and the fourth groove and the eighth groove are connected to form the fourth receiving groove.

[0013] Optionally, multiple elastic elements are provided, and multiple first receiving slots are provided, with each of the multiple elastic elements corresponding to one of the multiple first receiving slots.

[0014] This utility model provides an energy meter testing device, including a mounting bracket and a fastener. The mounting bracket is provided with an adjustment groove, and the fastener passes through the adjustment groove and is connected to the mounting base. The fastener can move along the adjustment groove to adjust the position of the mounting base on the mounting bracket.

[0015] This utility model provides an energy meter, and the energy meter testing device described herein is used in the testing of energy meter current, voltage and power.

[0016] This invention utilizes an automated current crimping block mounted on a mounting frame via a movable terminal tailstock. After adjustment to a suitable position, the contact portion of the contact sheet metal is inserted into the energy meter port. Pressing down on the connector causes the contact sheet metal to move downwards, gradually bringing the mounting portion of the contact sheet metal closer to the end of the elastic element located in the second receiving groove. This causes the elastic element to be compressed, generating elastic force. By applying external force, the connection between the energy meter and the contact sheet metal is pressed tightly, keeping the connector in a pressed state. At this time, the elastic force generated by the downward pressure of the elastic element acts on the contact sheet metal, causing the contact portion of the contact sheet metal to elastically contact the copper sheet in the energy meter port, enhancing the contact effect, improving testing efficiency and the accuracy of test data, and simplifying the manual screw crimping operation process.

[0027] like Figures 1 to 4 As shown, one embodiment of this utility model provides an automated current crimping block for a mobile terminal tail, including a mounting base 1, an elastic element 3, a contact sheet metal 2, and a connector 4. The contact sheet metal 2 includes an interconnected mounting portion 22 and a contact portion 21. The mounting base 1 is provided with a first receiving groove and a second receiving groove that are interconnected. One end of the elastic element 3 is installed in the first receiving groove, and the other end of the elastic element 3 is located in the second receiving groove. The mounting portion 22 is installed in the second receiving groove, and the contact portion 21 is used to insert into the port of an electricity meter. One end of the connector 4 is connected to the mounting portion 22. Pressing the other end of the connector 4 can drive the mounting portion 22 to move in the second receiving groove along a first direction and squeeze the elastic element 3. The elastic element 3 is used to provide elastic force so that the contact portion 21 abuts against the copper sheet of the electricity meter port. Here, the first direction is the movement direction of the connector 4. The mounting base 1 is a support member for the automated current crimping block for a mobile terminal tail and is used to install other components of the automated current crimping block for a mobile terminal tail.

[0028] As an example, the automated current crimping block for the mobile terminal block includes a mounting base 1, an elastic element 3, a contact sheet metal 2, and a connector 4. The mounting base 1 has a first receiving groove and a second receiving groove that are interconnected. The first receiving groove extends along a first direction, and the second receiving groove extends through the mounting base 1 along a second direction (perpendicular to the first direction). In this example, two elastic elements 3 and two first receiving grooves are provided, with each elastic element 3 placed in a corresponding position within the first receiving groove. The contact sheet metal 2 extends through the second receiving groove and protrudes from both ends of the second receiving groove. One end protruding from the second receiving groove is a contact portion 21, connected to the port of the energy meter, and the other end protruding from the second receiving groove is connected to an external wiring connection. One end of the elastic element 3 connects to the contact portion 21. One end of the contact sheet 2 is elastically connected in the first direction, and the other end of the contact sheet 2 in the first direction is fixedly connected to the end of the connector 4 near the second receiving groove. Pressing the end of the connector 4 away from the second receiving groove in the first direction can drive the contact sheet 2 to move downward. The mounting part 22 of the contact sheet 2 can gradually approach the end of the elastic member 3 located in the second receiving groove, so that the elastic member 3 is squeezed and generates elastic force. By applying external force to press the connection between the energy meter and the contact sheet 2, the connector 4 is kept in a downward state. At this time, the elastic force generated by the downward pressing of the elastic member 3 acts on the contact sheet 2, so that the contact sheet 2 and the copper sheet of the energy meter port are in closer contact and are not easy to fall off.

[0029] In one embodiment, such as Figures 1-4 As shown, the mounting base 1 is provided with a third receiving groove, which is located at the end of the second receiving groove away from the first receiving groove. The third receiving groove is connected to the second receiving groove. One end of the connector 4 passes through the third receiving groove and is connected to the contact sheet metal 2. The other end of the connector 4 protrudes from the mounting base 1 in a first direction, which is up and down.

[0030] As an example, the mounting base 1 is provided with a third receiving groove, which extends up and down along the first direction and is located at the end of the second receiving groove away from the first receiving groove. The third receiving groove is connected to the second receiving groove, and the end of the third receiving groove away from the first receiving groove passes through the mounting base 1. The threaded end of the connector 4 passes through the third receiving groove and is threadedly connected to the contact sheet 2. The other end of the connector 4 protrudes upward from the mounting base 1. Pressing the end of the connector 4 that protrudes from the mounting base 1 causes the contact sheet 2 to move downward and compress the elastic member 3 to generate an upward elastic force, so that the contact sheet 2 and the copper sheet of the power meter port make a tighter and more reliable contact.

[0031] In one embodiment, such as Figures 3-4 As shown, the first receiving groove extends along the first direction, and the second receiving groove penetrates the mounting base 1 along the second direction; the first direction and the second direction are not parallel and do not coincide.

[0032] As an example, the elastic element 3 is installed in the first receiving groove, and the contact sheet metal 2 is installed in the second receiving groove and passes through the second receiving groove. In order for the contact sheet metal 2 to properly compress the elastic element 3, the first receiving groove is set along the movement direction of the contact sheet metal 2. One end of the contact sheet metal 2 contacts the power meter port, and the end in contact with the power meter port extends to the outside of the mounting base 1. In order to ensure the normal operation of the automatic current crimping block of the moving terminal tail seat, the first direction is preferably set vertically, the second direction is preferably set horizontally, and the first direction is perpendicular to the second direction.

[0033] In one embodiment, such as Figure 1 As shown, the automatic current crimping block for the moving terminal tail also includes a guide member 5 and a guide sleeve 6. The guide member 5 is connected to the contact sheet metal 2, and the guide sleeve 6 is installed on the mounting base 1. The guide member 5 is inserted into the guide sleeve 6 to guide the movement of the mounting part 22 in the first direction.

[0034] As an example, both the guide 5 and the guide sleeve 6 are installed in the mounting base 1. The guide 5 is a long screw with threads. One end of the guide 5 is threaded to the contact sheet metal 2, and the other end of the guide 5 is inserted into the guide sleeve 6 to ensure that the contact sheet metal 2 can perform linear reciprocating motion in the first direction.

[0035] In one embodiment, such as Figure 1 As shown, the mounting base 1 is provided with a fourth receiving groove, which is connected to the second receiving groove. The guide sleeve 6 is disposed in the fourth receiving groove, and the guide member 5 is connected to the side surface of the contact sheet metal 2 near the elastic member 3.

[0036] As an example, the mounting base 1 is provided with a fourth receiving groove, which extends along the first direction and communicates with the second receiving groove, and is spaced apart from the first receiving groove. The guide sleeve 6 is a thin steel tube with a hollow center. One end of the guide sleeve 6 is located in the fourth receiving groove, and the other end of the guide sleeve 6 is located in the second receiving groove. The guide member 5 is connected to the side of the contact sheet metal 2 near the elastic member 3 and can be smoothly inserted into the guide sleeve 6. The contact sheet metal 2 moves downward along the first direction to one end of the guide sleeve 6. The elastic member 3 and the guide sleeve 6 restrict the contact sheet metal 2 from continuing to move along the first direction. The guide sleeve 6 provides a guide for the contact sheet metal 2 to reciprocate linearly along the first direction.

[0037] In one embodiment, such as Figure 1-4As shown, the mounting base 1 includes a first support plate 11 and a second support plate 12 connected to each other. The first support plate 11 is provided with a first groove 111, a second groove 112, a third groove 113 and a fourth groove 114. The second support plate 12 is provided with a fifth groove 121, a sixth groove 122, a seventh groove 123 and an eighth groove 124. The first groove 111 and the fifth groove 121 are connected to form a first receiving groove, the second groove 112 and the sixth groove 122 are connected to form a second receiving groove, the third groove 113 and the seventh groove 123 are connected to form a third receiving groove, and the fourth groove 114 and the eighth groove 124 are connected to form a fourth receiving groove.

[0038] As an example, such as Figure 3-4 As shown, the mounting base 1 includes a first support plate 11 and a second support plate 12 that are connected to each other. The first support plate 11 and the second support plate 12 have multiple grooves that are connected one-to-one to form multiple receiving slots for installing other components.

[0039] In one embodiment, such as Figure 3-4 As shown, multiple elastic elements 3 are provided to further improve the contact effect between the contact part 21 and the copper sheet of the power meter port. Multiple first receiving grooves are provided, and multiple elastic elements 3 are correspondingly arranged in multiple first receiving grooves.

[0040] As an example, the elastic element 3 is a high-precision spring. There are two elastic elements 3. The mounting base 1 has two corresponding first receiving grooves. The two high-precision springs are placed in the first receiving grooves and protrude from the second receiving grooves. The protruding end supports the contact sheet metal 2 against the end of the second receiving groove that is close to the third receiving groove. At this time, the automatic current crimping block of the moving terminal tail seat is in a non-working state, and the connector 4 is not pressed down. When the contact sheet metal 2 moves away from the end of the second receiving groove and closes to the end of the third receiving groove, it presses the elastic element 3 downward in the first direction. At this time, the automatic current crimping block of the moving terminal tail seat is in a working state, and the connector 4 presses down on the contact sheet metal 2. After the connection between the contact sheet metal 2 and the energy meter port is pressed and fixed by the external equipment, the downward pressure of the connector 4 is released. Under the action of the elastic force generated by the compression of the elastic element 3, the contact sheet metal 2 moves upward in the first direction. The connection between the contact sheet metal 2 and the energy meter port is simultaneously subjected to the downward pressing force of the external equipment and the upward pressing force of the contact sheet metal 2, making the contact sheet metal 2 and the copper sheet of the energy meter port more tightly and reliably connected.

[0041] This utility model provides an energy meter testing device, including a mounting frame and at least one mobile terminal tail automatic current crimping block; the mobile terminal tail automatic current crimping block is mounted on the mounting frame.

[0042] As an example, the electricity meter testing device includes a mounting frame and four or eight movable terminal tail automatic current crimping blocks, which can be connected to four-port or eight-port electricity meters for testing and inspection. Connector 4 passes through the mounting frame and connects multiple movable terminal tail automatic current crimping blocks on the mounting frame.

[0043] In one embodiment, the electricity meter testing device further includes a fastener, and the mounting bracket is provided with an adjustment groove. The fastener passes through the adjustment groove and is connected to the mounting base 1. The fastener can move along the adjustment groove to adjust the position of the mounting base 1 on the mounting bracket.

[0044] As an example, the electricity meter testing device also includes fasteners, including a nut 8 and a fixing screw. The nut 8 is installed between the first support plate 11 and the second support plate 12. The mounting frame is provided with an adjustment groove. The fixing screw passes through the adjustment groove and cooperates with the nut 8 to fix the automatic current crimping block of the moving terminal tail seat. The fixing screw can move along the adjustment groove to adjust the position of the automatic current crimping block of the moving terminal tail seat on the mounting frame.

[0045] This utility model provides an electricity meter and the application of an electricity meter testing device in testing the current, voltage, and power of the electricity meter.

[0046] As an example, the energy meter is either four-port or eight-port. Four or eight movable terminal tail automatic current crimping blocks are installed on the mounting bracket. Fasteners are moved along the adjustment groove to adjust the position of the movable terminal tail automatic current crimping blocks on the mounting bracket. After proper adjustment, the energy meter is inserted into the contact portion 21 of the contact sheet metal 2. The external pneumatic pressure block includes a first pneumatic pressure block and a second moving pressure block. The first pneumatic pressure block presses one end of the connector 4 protruding from the mounting base 1 in a first direction, causing the contact sheet metal 2 to squeeze the elastic member 3 in the first direction. The second pneumatic pressure block presses the outer end face of the energy meter port that contacts the contact portion 21 in the first direction to firmly fix the energy meter. Then, the pressure of the first pneumatic pressure block on the connector 4 is released. Under the action of the elastic force generated by the compression of the elastic member 3, the contact sheet metal 2 moves upward, so that the copper sheet in the energy meter port can maintain a tight contact with the contact portion 21 for a long time and is not easy to fall off.

[0047] The above-described embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
