[0001] The present invention relates to an electronic device, particularly an electronic device having a terminal assembly that integrates multiple terminals. Background Art

[0002] In small and portable electronic devices such as electronic thermometers, there are usually components such as batteries, buzzers, and circuit boards. In the prior art, as shown in Patent Document 1 (refer to paragraphs 13 and Figure 3 ), the battery 3312 is electrically connected to the circuit board 34 by battery connection pieces 3311a and 3311b, and the buzzer 3212 is electrically connected to the circuit board 34 by buzzer connection pieces 324a and 324b. That is, the terminals connecting the battery and the buzzer to the substrate are discrete and independent components. When assembling the electronic device, the positive and negative terminals of the battery and the positive and negative terminals of the buzzer need to be respectively connected to the substrate (for example, soldered to the substrate). In addition, in the prior art, the buzzer often uses wires to connect to the substrate, and during assembly, the soldering and arrangement of the wires are very time-consuming.

[0003] Electronic devices usually also include other components such as a switch for switching the battery power supply. In the prior art, the switch usually uses two independent metal plate-like contacts to connect to the substrate respectively. However, since these metal plates lack a support structure, a fixing structure such as a claw or a guiding groove needs to be provided on the housing, making the structure of the electronic device complex.

[0004] As described above, in the prior art, the components of the electronic device are numerous, the assembly process is complicated, the assembly efficiency is low, which is not conducive to the miniaturization and integration of the product. Due to the large number of components, processes, and uncontrollable factors, poor contact is likely to occur, resulting in a decrease in the yield rate and an increase in cost.

[0027] Next, the detailed embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0028] Hereinafter, taking the electronic thermometer as an example, the detailed embodiments of the present invention will be described.

[0029] Figure 1 Is a perspective view of the electronic thermometer 1 according to an embodiment of the present invention. Figure 2 Is an exploded view of the electronic thermometer 1 according to an embodiment of the present invention.

[0030] As Figure 1 、 Figure 2 shown, the electronic thermometer 1 has a housing 11 and a temperature measuring part 12. The housing 11 includes a front housing 11a connected to the temperature measuring part 12 and a rear housing 11b closing the tail end of the front housing 11a. A display window 11d for displaying the temperature measurement result is provided in the main body part of the front housing 11a, and the temperature measuring part 12 is provided at the front end of the protruding part on the front side of the front housing 11a. The temperature measuring part 12 contacts the object to be measured and measures the body temperature signal of the object to be measured. An opening is provided at the end of the rear housing 11b, and a switch part 11c for performing operation control such as switching the power supply of the electronic thermometer 1 is provided.

[0031] As Figure 2 shown, the housing 11 houses the components of the electronic thermometer 1. For example, an auxiliary bracket 20, a display screen assembly 21, a substrate 22, a terminal assembly 30, a button battery 40, a buzzer 50, etc. The button battery 40 and the buzzer 50 are mounted on the terminal assembly 30, and components such as the display screen assembly 21, the substrate 22, and the terminal assembly 30 are mounted on the auxiliary bracket 20, and the auxiliary bracket 20 is housed in the housing 11. Figure 2Among them, the locator 23 and the fixing screw 24 are used for positioning during the assembly of the electronic thermometer 1. The wire 25 connects the temperature measuring part 12 to the substrate 22.

[0032] The following will Figure 2 describe each component in detail.

[0033] For the convenience of explanation, hereinafter, Figure 1 , Figure 2 the upper side in is called the front side of the electronic thermometer 1, and the lower side is called the back side of the electronic thermometer 1.

[0034] Figure 3 is an exploded view showing the assembly relationship of each component of the electronic thermometer 1.

[0035] Note that, contrary to Figure 2 , Figure 3 the upper side in is the back side of the electronic thermometer 1, and the lower side is the front side of the electronic thermometer 1.

[0036] Referring to Figure 2 , Figure 3 , the components mounted on the auxiliary bracket 20 include the display screen assembly 21, the substrate 22, and the terminal assembly 30. The button battery 40 and the buzzer 50 are mounted on the terminal assembly 30.

[0037] The display screen assembly 21 includes the liquid crystal screen 211, the light guide plate 212 located between the liquid crystal screen 211 and the substrate 22, and the conductive rubber 213 that connects the liquid crystal screen 211 and the substrate 22 and drives the liquid crystal screen 211 to display.

[0038] The display screen assembly 21 is placed in the display screen receiving part 210 of the auxiliary bracket 20, and the display area of the liquid crystal screen 211 is exposed from the window 210a on the front of the auxiliary bracket 20. The periphery of the display screen receiving part 210 is formed by the side wall of the auxiliary bracket 20.

[0039] The light guide plate 212 evenly guides the light emitted by the LED 221 provided on the substrate 22 to the display area of the liquid crystal screen 211. The light guide plate 212 is provided with a notch 212a for accommodating the conductive rubber 213, and the conductive rubber 213 is arranged in the notch 212a, which can prevent the conductive rubber 213 from being bent and deformed during the stress process and the resulting poor contact.

[0040] Regarding the specific form of installing the button battery 40 and the buzzer 50 in the auxiliary bracket 20, it will be described in detail later with reference to Figure 3 .

[0041] In this embodiment, the positive terminal and negative terminal of the button battery 40, the positive terminal and negative terminal of the switch unit 11c, and the positive terminal and negative terminal of the buzzer 50 are integrated into one component of the terminal assembly 30. The switch unit 11c, button battery 40, and buzzer 50 are connected to the substrate 22 through the terminal assembly 30.

[0042] The terminal assembly 30 is fixed within the auxiliary bracket 20. The button battery 40 is pressed into the space between the positive terminal and negative terminal of the button battery 40 on the auxiliary bracket 20. The buzzer 50 is pressed between the auxiliary bracket 20 and the terminal assembly 30. The button battery 40 is connected to the substrate 22 through the terminal assembly 30 to supply power to the substrate 22. The buzzer 50 is connected to the substrate 22 through the terminal assembly 30 and emits a prompt sound according to the audio signal output by the substrate 22.

[0043] The button battery 40 and buzzer 50 are firmly fixed through the terminal assembly 30, thus ensuring a good connection between the button battery 40, buzzer 50 and the substrate 22.

[0044] As described above, since the terminal assembly 30 integrates various terminals into one body, it can not only ensure a good electrical connection between components such as the button battery 40 and buzzer 50 and the substrate 22, but also make the product structure compact and simple.

[0045] Furthermore, since the terminal assembly 30 integrates various terminals into one body, during assembly, only by snapping and fixing the terminal assembly 30 with the auxiliary bracket 20, the installation of all terminals is completed. Compared with the situation in the prior art where each terminal must be separately connected to the auxiliary bracket and the substrate, the production efficiency is greatly improved. Since the number of components is reduced, the assembly process is reduced, and the uncontrollable factors are reduced, the occurrence of poor contact is greatly suppressed, and the yield rate is improved.

[0046] (Terminal assembly 30)

[0047] The structure of the terminal assembly 30 will be described in detail below.

[0048] Figure 4 and Figure 5 are perspective views of the terminal assembly 30 of the electronic thermometer 1 according to an embodiment of the present invention, where Figure 4 is the perspective view of the terminal assembly when viewed from the front, Figure 5 is the perspective view of the terminal assembly when viewed from the back.

[0049] As Figure 4 and Figure 5 shown, the terminal assembly 30 includes: the positive electrode 40a and negative electrode 40b of the button battery 40 (see Figure 2 、 Figure 3)The crimped battery positive terminal 32a and battery negative terminal 32b; the positive electrode 50a and negative electrode 50b of the buzzer 50 (see Figure 3 )The crimped buzzer positive terminal 34a and buzzer negative terminal 34b; the switch terminal 33a; and the battery positive electrode board terminal 32c, battery negative electrode board terminal 32d, buzzer positive electrode board terminal 34c, buzzer negative electrode board terminal 34d, and switch board terminal 33c that connect the above respective terminals to the substrate 22 respectively.

[0050] The terminal assembly 30 has a resin support body 31, and the support body 31 integrally supports the battery positive terminal 32a, battery negative terminal 32b, switch terminal 33a, buzzer positive terminal 34a, buzzer negative terminal 34b, and the battery positive electrode board terminal 32c, battery negative electrode board terminal 32d, switch board terminal 33c, buzzer positive electrode board terminal 34c, and buzzer negative electrode board terminal 34d.

[0051] As described below, the support body 31 engages with the auxiliary support 20, thereby fixing the terminal assembly 30 to the auxiliary support 20.

[0052] The switch terminal 33a is mechanically connected to the switch portion 11c and serves as a movable terminal of the switch portion 11c; the terminal 33b integrally extending from the battery negative terminal 32b is opposed to the switch terminal 33a and serves as a switch fixed terminal. By pressing the switch portion 11c, the switch terminal 33a contacts or separates from the switch fixed terminal 33b, that is, the battery negative terminal 32b, thereby realizing the switching of power supply on / off.

[0053] The support body 31 is made of a resin material, preferably made of a resin with a relatively high hardness, such as polycarbonate resin. Since the support body 31 is made of a resin with a relatively high hardness such as polycarbonate resin, the support body 31 has a sufficiently high mechanical strength, is not easily deformed, and can effectively support the respective terminals in the terminal assembly 30.

[0054] In addition, as described below, the support body 31 also serves as a buzzer cover, applying a uniform pressing force to the outer peripheral edge of the buzzer 50. The support body 31 is made of a resin with a high hardness and is not easily deformed, making the pressing force on the buzzer uniform, which is beneficial to the sound generation of the buzzer.

[0055] As described above, since the terminal assembly 30 integrates all the terminals of the button battery 40, the switch portion 11c, and the buzzer 50, during assembly, only by engaging and fixing the terminal assembly 30 with the auxiliary support 20, the installation of all the terminals is completed. Compared with the prior art, the production efficiency and the yield rate are greatly improved.

[0056] Figure 6It is a perspective view of the support body 31 of the terminal assembly 30 of the present invention.

[0057] As Figure 4 , Figure 5 , Figure 6 shown, the support body 31 is in the shape of a "work" character, having two mutually parallel laterally extending portions 31a, 31b, and a longitudinally extending portion 31c connecting the substantially central portions of the laterally extending portions 31a, 31b. In this embodiment, the support body 31 is located at one end of the terminal assembly 30.

[0058] As Figure 4 , Figure 5 shown, one ends of the battery substrate terminals 32c, 32d, the switch substrate terminal 33c, and the buzzer substrate terminals 34c, 34d are fixed within the laterally extending portions 31a, 31b, and the other ends of these substrate terminals extend out from the laterally extending portions 31a, 31b towards the substrate 22.

[0059] As Figure 4 , Figure 5 , Figure 6 shown, a claw portion 311 is provided at each of the two ends of the laterally extending portion 31a of the support body 31 and one end of the laterally extending portion 31b, for a total of three claw portions 311. A card slot 201 (see Figure 3 ) is provided at a position corresponding to the claw portion 311 on the inner wall of the auxiliary support 20. When assembling the terminal assembly 30 into the auxiliary support 20, the claw portion 311 of the support body 31 is engaged with the card slot 201 on the inner wall of the auxiliary support 20, fixing the terminal assembly 30 within the auxiliary support 20. That is, by engaging the support body 31 with the auxiliary support 20, the terminal assembly 30 is fixed within the auxiliary support 20, completing the installation of all the terminals provided on the terminal assembly 30, greatly improving the production efficiency and the yield rate.

[0060] As Figure 5 , Figure 6 shown, a protruding portion 312 protruding towards the substrate 22 is provided on the longitudinally extending portion 31c of the support body 31. When assembling the terminal assembly 30 into the auxiliary support 20, the robot can hold the protruding portion 312, facilitating the assembly. In addition, as described below, the protruding portion 312 is also beneficial for fixing the buzzer 50 below it.

[0061] One ends of the buzzer positive terminal 34a and the buzzer negative terminal 34b are fixed within the laterally extending portion 31a, and are respectively connected to the buzzer positive substrate terminal 34c and the buzzer negative substrate terminal 34d. The other ends of the buzzer positive terminal 34a and the buzzer negative terminal 34b extend out from the laterally extending portion 31a towards the auxiliary support 20.

[0062] As described above, the laterally extending portions 31a and 31b respectively support a plurality of positive terminal ends, negative terminal ends, switch terminal ends, and substrate terminal ends, and the longitudinally extending portion 31c connects the laterally extending portions 31a and 31b to integrate the bracket body 31. By forming the laterally extending portions 31a and 31b and the longitudinally extending portion 31c, the strength of the bracket body 31 can be increased, and these terminal ends can be stably supported.

[0063] Hereinafter, with reference to Figure 3 and Figures 7 - 9 , the terminal ends related to the button battery 40, the terminal ends related to the buzzer 50, and the terminal ends related to the switch portion 11c will be specifically described.

[0064] (Installation of Battery Terminal and Button Battery)

[0065] Figure 7 is a top view of the structure related to the button battery in the electronic thermometer 1 according to an embodiment of the present invention.

[0066] As Figure 3 , Figure 7 shown, a battery housing portion 205 is formed on the back side of the auxiliary bracket 20. A battery support wall portion 205a having a shape substantially the same as that of the button battery 40 is formed on one side of the battery housing portion 205. A battery claw 205b is formed at the back side end of the battery support wall portion 205a (see Figure 8 ). On the bottom surface of the auxiliary bracket 20, adjacent to the battery support wall portion 205a, battery support walls 205c and 205d, and a battery claw 205e are further formed, so as to firmly fix the button battery 40 to the auxiliary bracket 20.

[0067] In a state where the terminal assembly 30 is installed in the auxiliary bracket 20, the battery positive terminal end 32a is located on the opposite side of the battery support wall portion 205a, and the button battery 40 is installed between the battery positive terminal end 32a and the battery support wall portions 205a, 205c, and 205d.

[0068] As Figure 3 , Figure 5 , Figure 7 shown, the battery positive terminal end 32a has V-shaped walls 32a1 and 32a2. The V-shaped walls 32a1 and 32a2 are elastic and can clamp the button battery 40 to fix the button battery 40. Since a battery claw 205b is provided at the back side end of the battery support wall portion 205a, the button battery 40 can be stably clamped, preventing the button battery 40 from accidentally falling off due to vibration or the like.

[0069] Since the battery positive terminal end 32a is V-shaped and has the V-shaped walls 32a1 and 32a2, the button battery 40 can be well fixed, and good contact with the button battery 40 can also be ensured.

[0070] When the button battery 40 is clamped by the battery positive terminal 32a, due to the extrusion of the button battery 40, the battery positive terminal 32a will undergo a large deformation in the direction perpendicular to the pressing direction of the button battery 40 ( Figure 7 the direction perpendicular to the paper surface in the middle). Figure 7 In the present embodiment, as Figure 7 shown, on the bottom surface of the auxiliary bracket 20, side walls 206 are provided at positions corresponding to the V-shaped walls 32a1 and 32a2 outside the V-shaped walls 32a1 and 32a2, serving as a limiting portion. When the button battery 40 is pressed in, when the V-shaped walls 32a1 and 32a2 deform in the direction perpendicular to the pressing direction of the button battery 40 and move outward, the limiting portion 206 can effectively suppress the deformation of the V-shaped walls 32a1 and 32a2.

[0071] As Figure 3 , Figure 5 , Figure 6 shown, on the lateral extension portion 31b of the bracket body 31, two battery limiting pins 315 are provided. The battery limiting pins 315, together with the battery support walls 205a, 205c, 205d, and the battery positive terminal 32a, limit the position of the button battery 40 to prevent the button battery 40 from moving within the auxiliary bracket 20.

[0072] When the button battery 40 is pressed in, due to the extrusion of the button battery 40, it may cause the battery positive terminal 32a and the connecting portion 32e between the battery positive terminal 32a and the battery substrate terminal 32c to twist and rotate relative to the auxiliary bracket 20.

[0073] Figure 8 FIG.

[0074] In the present embodiment, as Figure 4 , Figure 5 , Figure 8 shown, the connecting portion 32e between the battery positive terminal 32a and the battery substrate terminal 32c branches into two paths at the bending portion that folds towards the V-shaped top of the battery positive terminal 32a. One path reaches the V-shaped top of the battery positive terminal 32a, and the other path extends towards the auxiliary bracket 20 to form an extending portion 32f. An embedding hole 207 is formed on the bottom surface of the auxiliary bracket 20 at a position corresponding to the extending portion 32f, and the extending portion 32f is embedded in the embedding hole 207, thereby suppressing the twisting and rotation of the battery positive terminal 32a and the connecting portion 32e relative to the auxiliary bracket 20.

[0075] (Switch terminal)

[0076] AsFigure 4 and Figure 5 As shown in Figure 5 , the switch terminal 33a is a movable switch terminal, which is opposed to the fixed switch terminal 33b. The switch terminal 33a is connected to the substrate 22 through the switch substrate terminal 33c. The fixed switch terminal 33b is integrated with the battery negative terminal 32b and is connected to the substrate 22 through the battery negative substrate terminal 32d. When the switch portion 11c is pressed, the switch portion 11c drives the switch terminal 33a to move, so that the switch terminal 33a contacts the fixed switch terminal 33b, forming a loop, and starting the power supply of the battery 40; when the switch portion 11c is released, the switch terminal 33a is disconnected from the fixed switch terminal 33b, and the power supply of the battery 40 is stopped.

[0077] (Buzzer terminal)

[0078] In the present embodiment, as Figure 3 shown in Figure 3 , a buzzer housing portion 204 is formed on the back side of the auxiliary bracket 20. The inner wall surface shape at the buzzer housing portion 204 is substantially the same as that of the buzzer 50, which is easy to place the buzzer 50 and can position the buzzer 50. A relief groove 208 for the buzzer 50 is formed on the bottom surface of the front side of the buzzer housing portion 204, and the diameter of the relief groove 208 is slightly smaller than the outer diameter of the buzzer 50.

[0079] As Figure 4 shown in Figure 4 , on the front side of the bracket body 31 of the terminal assembly 30, on the laterally extending portions 31a, 31b, a buzzer relief groove 314 is formed. Similarly, the shape of the buzzer relief groove 314 is slightly smaller than the outer diameter of the buzzer 50.

[0080] In the present embodiment, in the assembled state of the buzzer 50, the front and back sides of the buzzer 50 are respectively clamped by the relief groove 208 and the buzzer relief groove 314, and are fixed between the bracket body 31 and the auxiliary bracket 20. The ends of the buzzer positive terminal 34a and the buzzer negative terminal 34b extending from the laterally extending portion 31a of the bracket body 31 abut against the buzzer 50 in the direction of the auxiliary bracket 20, thereby stably electrically connecting the buzzer 50 to the substrate 22.

[0081] Since the bracket body 31 is made of a resin with a relatively high hardness, after the buzzer 50 and the terminal assembly 30 are assembled into the auxiliary bracket 20, the bracket body 31 can apply a uniform pressing force to the outer periphery of the buzzer 50. The uniform pressing force received by the buzzer 50 is beneficial to the buzzer 50 to emit sound.

[0082] (Assembly of the electronic thermometer 1)

[0083] As Figure 3As shown, when the display component 21 and the buzzer 50 are respectively placed in the display component receiving portion 210 and the buzzer receiving portion 204 of the auxiliary bracket 20, and the terminal component 30 is loaded into the auxiliary bracket 20, the claw portion 311 of the bracket body 21 is engaged with the card slot 201 of the auxiliary bracket 20. After that, when the substrate 22 is assembled onto the auxiliary bracket 20, the protruding portion 312 on the bracket body 21 is engaged with the groove portion 222 formed on the substrate 22, which can improve the positioning accuracy of the substrate 22 and the auxiliary bracket 20. In the state where the protruding portion 312 of the bracket body 21 is engaged with the groove portion 222 on the substrate 22, the substrate 22 covers all areas of the bracket body 31 except the longitudinally extending portion 31c. Therefore, in the assembled state, the battery substrate terminals 32c, 32d, the switch substrate terminal 33c, and the buzzer substrate terminals 34c, 34d that extend from the laterally extending portions 31a, 31b and contact the substrate 22 are all covered by the substrate 22. So, for example, when the user replaces the battery, these terminals will not be touched, which can improve the reliability of the product.

[0084] As Figure 2 shown, after the substrate 22 is assembled to the back side of the auxiliary bracket 20, and the button battery 40 and the buzzer 50 are installed on the auxiliary bracket 20, the assembly of the core of the electronic thermometer 1 is completed. Then, a part of the substrate 22 and a part of the bracket body 31 of the terminal component 30 are pressed from the back side by the locator 23, and together with the locator 23, the components of the assembled electronic thermometer 1 are loaded into the front housing 11a from the tail end opening of the cylindrical front housing 11a, and the locator 23 reaches inside the front housing 11a. In this state, the rear housing 11b is closed with the front housing 11a, and the fixing screw 24 is passed through the holes of the rear housing 11b and the front housing 11a and screwed into the screw hole of the locator 23. Finally, the temperature measuring part 12 is installed at the front end of the front auxiliary bracket 11a, and the temperature measuring part 12 is connected to the substrate 22 through the wire 25.

[0085] The locator 23 includes a positioning pin 234 corresponding to the positioning hole 224 on the substrate 22, for positioning the substrate 22, the auxiliary bracket 20 and the components thereof with each other.

[0086] In the state where the components are installed in the front housing 11a and the rear housing 11b together with the locator 23, the locator 23 presses the protruding portion 312 of the bracket body 31, so as to adjust the pressure on the buzzer 50.

[0087] Figure 9 is a perspective view of the structure related to the buzzer 50 in the electronic thermometer 1 according to an embodiment of the present invention.
