[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an electronic thermometer.

[0002]

[Prior art]

 As shown in FIG. 1, a battery and a circuit board are installed in a general electronic thermometer by a locking type. A plurality of locking hooks 311 are formed on the side of the base 31 of the electronic device 3. The circuit board 32 mounted on the base 31 is locked by the locking hook 311. A connection hook 3121 is also formed on the peripheral edge of the battery mounting base 312 at one end of the base 31. The battery 33 of the battery mount 312 is locked by the locking hook 3121. The fixed circuit board 32 is stably fixed by the locking hook 311 having the locking structure. When a battery 33 having an irregular standard and size is used and a small-sized battery is installed, phenomena such as loosening of the battery mounting base 312, poor contact with the elastic thin piece for electrical conduction, and falling off of the battery 33 occur. .

[0005] Therefore, as shown in FIG. 2, a cover is formed so as to improve the drawbacks of the locking structure. The base 41 of the electronic device 4 has a U-shaped cross section, and a positioning cover 411 is integrally installed on one side of the base 41. When the base 41 is covered with the positioning cover 411, the circuit board 42 installed on the base 41 is locked to the positioning cover 411 by the locking hooks 4111, and the circuit board 42 is tightened. A fastening thin piece 4121 is formed on the side of the battery mounting base 412 on the other side of the base 41 in which the battery 43 is accommodated. The battery 43 housed by the hook 4122 at the peripheral edge of the battery mount 412 is locked, covered with the fastening thin piece 4121, and fastened. Therefore, the battery 43 does not have poor contact or fall off. However, when the positioning cover 411 and the fastening lamella 4121 are installed, the manufacturing cost increases.

[0004]

[Problem to be Solved by the Invention] Therefore, an object of the invention is to provide an electronic thermometer which has good quality and can reduce the manufacturing cost.

The battery mount has a semicircular side opening through which a battery can be inserted. A metal guide contact surface is installed on the circuit board so that the negative pole surface of the battery is in close contact, and a conductive elastic flake is installed inside the electronic device so that the positive pole surface of the battery is in contact. Have been. When the electronic device is inserted into the outer shell, the side opening is closed by the inner wall of the outer shell to prevent the battery from falling. The circuit board is fixed to the electronic device with screws.

[0006] The battery is inserted from the side opening and is covered and fixed to the battery mount, so that the battery is easily stored. The circuit board is fixed by screws, and the battery is pressed above the battery mount, so that the battery and the circuit board are in stable contact. As a result, product quality is improved and manufacturing costs can be reduced.

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIGS. 3 and 4, an electronic thermometer according to an embodiment of the present invention includes an outer shell 1 and an electronic device 2. The outer shell 1 is a hollow rectangular body, and a sharp temperature sensing portion 11 is formed at one end, and an opening 12 communicating with the hollow inside of the outer shell 1 is formed at the other end. A cap 13 is provided in the opening 12, and the outer shell 1 is sealed. A window is formed on one side of the outer shell 1.

The electronic device 2 is inserted into the outer shell 1 from the opening 12 of the outer shell 1 and fixed. The base 21 of the electronic device 2 has a U-shaped cross section. A display device protrudes from the upper surface of the base 21 at a position corresponding to the window of the outer shell 1. Further, a buzzer is installed inside the base 21 and a circuit board 22 is connected thereto. The circuit board 22 is connected to the display device via a rubber for electricity. Electric power is supplied by a battery 23 installed on a battery mount 212 at the end of the base 21.

A mounting hole 211 is formed in the base 21 and the battery mounting base 212 of the electronic device 2. The screw 213 penetrates the circuit board 22 and is screwed into the mounting hole 211 of the base 21. One end of the circuit board 22 extends and is connected to the battery mount 212. A metal guide contact surface 221 is provided on the circuit board at a position corresponding to the position above the battery mount 212. A semicircular side opening 2121 is formed in the battery mount 212. The battery 23 is inserted from the side opening 2121. An energizing elastic piece 24 is provided inside the electronic device so that the positive pole surface of the battery 23 is in contact with the battery. As shown in FIGS. 5 and 7, the circuit board 22 covers and presses the battery mount 212, so that when the battery 23 is installed on the battery mount 212, as shown in FIG. The negative pole surface is in contact with the upper part of the circuit board 22, and the battery 23 is in close contact with the circuit board 22. That is, the negative pole surface of the battery 23 is in close contact with the guide contact surface 221. For this reason, it is stably fixed and is in conductive contact.

As shown in FIG. 6, when the battery 23 is installed and the electronic device 2 is installed inside the outer shell 1, the side opening 2121 of the battery mounting base 212 becomes the inner wall of the outer shell 1. The battery 23 is stably fixed without falling to the outside.

[0011] The circuit board is easily installed by a tightening method, and is in stable contact with the battery. Since the battery installation structure is a convenient structure, the manufacturing cost can be reduced as compared with a conventional electronic thermometer.
