[0063] This embodiment provides a measurement switch that has high operating efficiency and ensures stable internal power supply, thereby preventing data loss in the event of an external power outage. The operating principle of the measurement switch is described in detail herein, with reference to the prior art.

[0064] Specifically, if Figures 1 to 10As shown, the measuring switch includes a shell 1 and a battery compartment 2; wherein the shell 1 is provided with a accommodating cavity; the battery compartment 2 is slidably matched with the accommodating cavity, and one of the battery compartment 2 and the accommodating cavity is provided with a first self-locking piece 2124, and the other is provided with a first self-locking groove 112; the battery compartment 2 can be inserted into the accommodating cavity along the X-axis, the first self-locking piece 2124 is inserted into the first self-locking groove 112, and the first outer surface 2131 of the battery compartment 2 is exposed to the second outer surface 13 of the shell 1; the battery compartment 2 can slide out of the accommodating cavity along the X-axis, and the first self-locking piece 2124 is disengaged from the first self-locking groove 112.

[0065] Compared with the prior art, the measuring switch in this embodiment changes the installation method of the battery compartment 2 on the shell 1, and adds a first self-locking piece 2124 and a first self-locking groove 112 that cooperate with each other; by providing the first self-locking piece 2124 in one of the battery compartment 2 and the accommodating cavity, and providing the first self-locking groove 112 in the other; when the battery compartment 2 is inserted into the accommodating cavity along the X axis, the first self-locking piece 2124 is inserted into the first self-locking groove 112, and the first outer surface 2131 of the battery compartment 2 is exposed to the second outer surface 13 of the shell 1; when the battery compartment 2 slides out of the accommodating cavity along the X axis, the first self-locking piece 2124 is disengaged from the first self-locking groove 112; using the above method, when replacing the battery cell 22 of the battery compartment 2, due to the first outer surface 2131 of the battery compartment 2 131 is exposed on the second outer surface 13 of the shell 1. The battery cell 22 of the battery compartment 2 can be replaced by sliding the entire battery compartment 2 out of the accommodating cavity along the X-axis through the first outer surface 2131 of the battery compartment 2, making the operation of replacing the battery cell 22 simple and convenient, saving time and effort, thereby ensuring that the working efficiency of the measuring switch is high; and when the battery compartment 2 is slid along the X-axis into the accommodating cavity, the first self-locking member 2124 is inserted into the first self-locking groove 112, so that a self-locking structure is formed between the battery compartment 2 and the accommodating cavity, ensuring the stability of the installation of the battery compartment 2 in the accommodating cavity, and preventing shaking problems, thereby ensuring good contact between the battery cell 22 of the battery compartment 2 and the circuit board 4 of the measuring switch, thereby ensuring the power supply stability of the battery cell 22.

[0066] In the current measuring switch, the battery cell 22 of the battery compartment 2 is electrically connected to the circuit board 4 of the measuring switch through a wire. On the one hand, this can easily lead to poor contact between the battery cell 22 and the circuit board 4, making it impossible to ensure the power supply stability of the battery cell 22. On the other hand, the cross-connections between the various wires can easily lead to poor neatness and aesthetics of the entire measuring switch.

[0067] In order to solve the above problems, in this embodiment, Figures 2 to 10As shown, the measuring switch also includes a circuit board 4, which is arranged in the shell 1; the battery compartment 2 includes a shell frame 21, a battery cell 22, a negative conductive member 23 and a positive conductive member 24; wherein, the shell frame 21 is provided with a receiving groove 216, and the shell frame 21 slides with the receiving cavity; the battery cell 22 is arranged in the receiving groove 216; the negative conductive member 23 is arranged on the shell frame 21, and the two ends of the negative conductive member 23 can respectively abut the negative electrode of the battery cell 22 and the negative conductive sheet 42 on the circuit board 4; the positive conductive member 24 is provided on the shell frame 21, and the two ends of the positive conductive member 24 can respectively abut the positive electrode of the battery cell 22 and the positive conductive sheet 41 on the circuit board 4.

[0068] By providing the negative conductive member 23 and the positive conductive member 24 to achieve electrical connection between the battery cell 22 and the circuit board 4, there is no need to make an electrical connection through a wire. On the one hand, the connection method in which the negative conductive member 23 and the positive conductive member 24 abut against each other can ensure good contact between the battery cell 22 and the circuit board 4, thereby better ensuring the power supply stability of the battery cell 22; on the other hand, since the two conductive structures of the negative conductive member 23 and the positive conductive member 24 are separately provided, cross-connection between the various wires can be avoided, thereby ensuring the neatness and good aesthetics of the entire measuring switch.

[0069] Furthermore, if Figures 1 to 3 As shown, one of the frame 21 and the shell 1 is provided with a snap-fit ​​groove 2132, and the other is provided with a snap-fit ​​rib, which can be snapped into the snap-fit ​​groove 2132 to make the first outer surface 2131 of the frame 21 flush with the second outer surface 13 of the shell 1.

In addition, a portion of the second outer surface 13 of the housing 1 is the outer surface on the base 11, and the remaining portion of the second outer surface 13 of the housing 1 is the outer surface on the middle cover 12. The measuring switch also includes a transformer 3, which is disposed within the base 11, and a circuit board 4 is positioned within a slot in the transformer 3.

[0076] By providing a second self-locking piece 2115 and a second self-locking groove 43 that cooperate with each other, when the battery compartment 2 is slid along the X-axis and inserted into the accommodating cavity, the first self-locking piece 2124 can be inserted into the first self-locking groove 112, so that a self-locking structure can be formed between the battery compartment 2 and the accommodating cavity, further ensuring the installation stability of the battery compartment 2 in the accommodating cavity, and preventing the problem of shaking, thereby ensuring better contact between the battery cell 22 of the battery compartment 2 and the circuit board 4 of the measuring switch, and better ensuring the power supply stability of the battery cell 22.

[0077] In this embodiment, Figure 3 and Figure 4 As shown, a second self-locking member 2115 is provided on the shell frame 21, and a second self-locking groove 43 is provided on the circuit board 4. The second self-locking member 2115 can specifically be an arc-shaped block, and the second self-locking groove 43 is an arc-shaped groove, so as to provide a guide for the second self-locking member 2115 to be inserted into and slide out of the second self-locking groove 43, which is conducive to the second self-locking member 2115 to be inserted into or out of the second self-locking groove 43.
