Further, since the terminal assembly 30 integrates various terminals, when assembling, the terminal assembly 30 is only required to be fixed with the auxiliary bracket 20, that is, all the terminals are mounted, and compared with the prior art in which each terminal must be separately connected to the auxiliary bracket and the substrate, the production efficiency is greatly improved. Because the number of parts is reduced, the assembly process is reduced, uncontrollable factors are reduced, the occurrence of poor contact is greatly inhibited, and the yield is improved.
(terminal Assembly 30)
The structure of the terminal assembly 30 is described in detail below.
Fig. 4 and 5 are perspective views of the terminal assembly 30 of the electronic thermometer 1 according to one embodiment of the present invention, in which fig. 4 is a perspective view of the terminal assembly as viewed from the front, and fig. 5 is a perspective view of the terminal assembly as viewed from the back.
As shown in fig. 4 and 5, the terminal assembly 30 includes: a battery positive terminal 32a and a battery negative terminal 32b which are pressed with a positive electrode 40a and a negative electrode 40b (see fig. 2 and 3) of the button battery 40; a buzzer positive terminal 34a and a buzzer negative terminal 34b that are pressure-bonded to a positive electrode 50a and a negative electrode 50b (see fig. 3) of the buzzer 50; a switch terminal 33 a; and a battery positive electrode substrate terminal 32c, a battery negative electrode substrate terminal 32d, a buzzer positive electrode substrate terminal 34c, a buzzer negative electrode substrate terminal 34d, and a switch substrate terminal 33c, which connect the terminals to the substrate 22, respectively.
The terminal assembly 30 has a resin holder body 31, and the holder body 31 integrally supports a battery positive electrode terminal 32a, a battery negative electrode terminal 32b, a switch terminal 33a, a buzzer positive electrode terminal 34a, a buzzer negative electrode terminal 34b, and a battery positive electrode substrate terminal 32c, a battery negative electrode substrate terminal 32d, a switch substrate terminal 33c, a buzzer positive electrode substrate terminal 34c, and a buzzer negative electrode substrate terminal 34 d.
As described below, the bracket body 31 engages with the auxiliary bracket 20, thereby fixing the terminal assembly 30 to the auxiliary bracket 20.
The switch terminal 33a is mechanically connected to the switch unit 11c as a movable terminal of the switch unit 11 c; the terminal 33b integrally extending from the battery negative electrode terminal 32b faces the switch terminal 33a and functions as a switch fixing terminal, and when the switch portion 11c is pressed, the switch terminal 33a is brought into contact with or separated from the switch fixing terminal 33b, that is, the battery negative electrode terminal 32b, thereby switching between supply and interruption of the power supply.
The holder body 31 is made of a resin material, preferably, a resin having a high hardness, such as a polycarbonate resin. Since the holder body 31 is made of a resin having a high hardness such as a polycarbonate resin, the holder body 31 has a sufficiently high mechanical strength and is not easily deformed, and can effectively support each terminal in the terminal assembly 30.
In addition, as described below, the holder body 31 also functions as a buzzer cover to apply a uniform pressing force to the peripheral edge of the buzzer 50, and the holder body 31 is made of a resin having high hardness and being not easily deformed, so that the buzzer is uniformly pressed by the pressing force, which is advantageous for sounding the buzzer.
As described above, since the terminal assembly 30 integrates all the terminals of the button cell 40, the switch unit 11c, and the buzzer 50, when assembling, the terminal assembly 30 is only required to be engaged and fixed with the auxiliary bracket 20, and all the terminals are mounted, which greatly improves the production efficiency and the yield compared with the prior art.
Fig. 6 is a perspective view of the bracket body 31 of the terminal assembly 30 of the present invention.
As shown in fig. 4, 5, and 6, the stent body 31 has an i-shape, and includes two laterally extending portions 31a and 31b parallel to each other, and a longitudinally extending portion 31c connecting substantially central portions of the laterally extending portions 31a and 31 b. In this embodiment, the bracket body 31 is located at one end of the terminal assembly 30.
As shown in fig. 4 and 5, one ends of the battery board terminals 32c and 32d, the switch board terminal 33c, and the buzzer board terminals 34c and 34d are fixed in the laterally extending portions 31a and 31b, and the other ends of the board terminals extend from the laterally extending portions 31a and 31b toward the board 22.
As shown in fig. 4, 5 and 6, the two ends of the laterally extending portion 31a and one end of the laterally extending portion 31b of the holder body 31 are each provided with one claw portion 311, and there are three claw portions 311 in total. A locking groove 201 (see fig. 3) is provided in a position corresponding to the locking claw portion 311 on the inner wall of the auxiliary holder 20, and when the terminal assembly 30 is assembled into the auxiliary holder 20, the locking claw portion 311 of the holder body 31 is engaged with the locking groove 201 on the inner wall of the auxiliary holder 20, thereby fixing the terminal assembly 30 into the auxiliary holder 20. That is, the terminal assembly 30 is fixed in the auxiliary bracket 20 by engaging the bracket body 31 with the auxiliary bracket 20, and all the terminals provided on the terminal assembly 30 are mounted, thereby greatly improving the production efficiency and the yield.
As shown in fig. 5 and 6, a boss 312 protruding toward the base plate 22 is provided on the longitudinally extending portion 31c of the holder body 31. The protrusion 312 may be gripped by a robot when the terminal assembly 30 is assembled into the auxiliary bracket 20, thereby facilitating the assembly. In addition, the projection 312 also facilitates securing the buzzer 50 thereunder, as described below.
One ends of the buzzer positive terminal 34a and the buzzer negative terminal 34b are fixed in the lateral extension portion 31a, and are connected to the buzzer positive substrate terminal 34c and the buzzer negative substrate terminal 34d, respectively, and the other ends of the buzzer positive terminal 34a and the buzzer negative terminal 34b extend from the lateral extension portion 31a toward the auxiliary bracket 20.
As described above, the lateral extending portions 31a and 31b support the plurality of positive electrode terminals, negative electrode terminals, switch terminals, and board terminals, respectively, and the vertical extending portion 31c connects the lateral extending portions 31a and 31b to integrate the holder body 31. By forming the lateral extensions 31a, 31b and the longitudinal extension 31c, the strength of the holder body 31 can be improved, and the terminals can be stably supported.
Hereinafter, referring to fig. 3 and 7 to 9, a terminal related to the button cell 40, a terminal related to the buzzer 50, and a terminal related to the switch section 11c are described in detail.
(mounting of Battery terminal and button cell)
Fig. 7 is a plan view of a structure related to a button cell in the electronic thermometer 1 according to the embodiment of the present invention.
As shown in fig. 3 and 7, a battery housing portion 205 is formed on the rear surface side of the auxiliary holder 20, a battery support wall portion 205a having substantially the same shape as the button battery 40 is formed on one side of the battery housing portion 205, and a battery claw 205b is formed on the rear surface side end portion of the battery support wall portion 205a (see fig. 8). On the bottom surface of the sub-mount 20, adjacent to the battery support wall portion 205a, battery support walls 205c, 205d, and a battery claw 205e are further formed, thereby firmly fixing the button battery 40 to the sub-mount 20.
In a state in which the terminal assembly 30 is mounted into the auxiliary bracket 20, the battery positive terminal 32a is located on the opposite side of the battery support wall portion 205a, and the button battery 40 is mounted between the battery positive terminal 32a and the battery support wall portions 205a, 205c, 205 d.
As shown in fig. 3, 5 and 7, the battery positive terminal 32a has V-shaped walls 32a1 and 32a2, and the V-shaped walls 32a1 and 32a2 have elasticity and can clamp the button battery 40 and fix the button battery 40. Since the battery claws 205b are provided at the rear end of the battery support wall 205a, the button battery 40 can be stably held, and accidental detachment of the button battery 40 due to vibration or the like can be prevented.
Since the battery positive terminal 32a is V-shaped and has V-shaped walls 32a1 and 32a2, the button battery 40 can be well fixed and good contact with the button battery 40 can be ensured.
In a state where the button cell 40 is held by the battery positive electrode terminal 32a, the battery positive electrode terminal 32a is largely deformed in a direction (direction of the paper surface in fig. 7) perpendicular to a pressing direction (direction perpendicular to the paper surface in fig. 7) of the button cell 40 by the pressing of the button cell 40. In the present embodiment, as shown in fig. 7, a side wall 206 is provided on the bottom surface of the sub-bracket 20 at a position corresponding to the V-shaped walls 32a1 and 32a2 outside the V-shaped walls 32a1 and 32a2, and functions as a stopper. When the V-shaped walls 32a1 and 32a2 are deformed in the direction perpendicular to the pressing direction of the button cell 40 in the state where the button cell 40 is pressed, and move outward, the stopper 206 can effectively suppress the deformation of the V-shaped walls 32a1 and 32a 2.
As shown in fig. 3, 5 and 6, two battery stopper pins 315 are provided on the lateral extension 31b of the holder body 31, and the battery stopper pins 315, together with the battery support walls 205a, 205c and 205d and the battery positive terminal 32a, restrict the position of the button battery 40 and prevent the button battery 40 from moving in the auxiliary holder 20.
When the button battery 40 is pressed, the battery positive terminal 32a and the connection portion 32e of the battery positive terminal 32a and the battery substrate terminal 32c may twist and rotate relative to the auxiliary holder 20 due to the pressing of the button battery 40.
Fig. 8 is a perspective view of a structure related to the button battery 40 in the electronic thermometer 1 according to the embodiment of the present invention.
In the present embodiment, as shown in fig. 4, 5, and 8, the connection portion 32e between the battery positive terminal 32a and the battery board terminal 32c is divided into two branches at a bend folded toward the V-shaped top of the battery positive terminal 32a, one branch reaching the V-shaped top of the battery positive terminal 32a and the other branch extending toward the auxiliary holder 20 to form an extending portion 32 f. An insertion hole 207 is formed in the bottom surface of the auxiliary holder 20 at a position corresponding to the protruding portion 32f, and the protruding portion 32f is inserted into the insertion hole 207, thereby suppressing twisting and rotation of the battery positive electrode terminal 32a and the connecting portion 32e with respect to the auxiliary holder 20.
(switch terminal)
As shown in fig. 4 and 5, the switch terminal 33a is a movable switch terminal and faces the switch fixed terminal 33b, the switch terminal 33a is connected to the substrate 22 through the switch substrate terminal 33c, the switch fixed terminal 33b is integrated with the battery negative electrode terminal 32b, and is connected to the substrate 22 through the battery negative electrode substrate terminal 32 d. When the switch part 11c is pressed, the switch part 11c drives the switch terminal 33a to move, so that the switch terminal 33a contacts with the switch fixed terminal 33b to be connected into a loop, and the power supply of the battery 40 is started; when the switch unit 11c is released, the switch terminal 33a and the switch fixing terminal 33b are disconnected, and the power supply of the battery 40 is stopped.
(buzzer terminal)
In the present embodiment, as shown in fig. 3, a buzzer housing portion 204 is formed on the back surface side of the auxiliary holder 20, and the shape of the inner wall surface of the buzzer housing portion 204 is substantially the same as that of the buzzer 50, so that the buzzer 50 can be easily placed and the buzzer 50 can be positioned. A recess groove 208 of the buzzer 50 is formed in the front-side bottom surface of the buzzer housing portion 204, and the diameter of the recess groove 208 is slightly smaller than the outer diameter of the buzzer 50.
As shown in fig. 4, on the front surface side of the holder body 31 of the terminal assembly 30, on the lateral extending portions 31a, 31b, buzzer avoiding grooves 314 are formed. Also, the buzzer relief groove 314 is shaped slightly smaller than the outer diameter of the buzzer 50.
In the present embodiment, in the assembled state of the buzzer 50, both the front and back sides of the buzzer 50 are held between the holder body 31 and the auxiliary holder 20 by the relief groove 208 and the buzzer relief groove 314, respectively, and the ends of the buzzer positive electrode terminal 34a and the buzzer negative electrode terminal 34b protruding from the lateral extension 31a of the holder body 31 abut against the buzzer 50 in the direction of the auxiliary holder 20, thereby electrically connecting the buzzer 50 and the substrate 22 stably.
Since the holder body 31 is made of a resin having a high hardness, it is possible to apply a uniform pressing force to the outer periphery of the buzzer 50 by the holder body 31 after the buzzer 50 and the terminal assembly 30 are assembled into the auxiliary holder 20. The buzzer 50 is uniformly pressed to generate sound.

As shown in fig. 3, the display panel unit 21 and the buzzer 50 are placed in the display panel unit housing portion 210 and the buzzer housing portion 204 of the auxiliary holder 20, respectively, and the terminal unit 30 is mounted in the auxiliary holder 20 such that the claw portion 311 of the holder body 21 is engaged with the engaging groove 201 of the auxiliary holder 20. Thereafter, when the substrate 22 is assembled to the sub-holder 20, the convex portion 312 of the holder body 21 is fitted in the groove portion 222 formed in the substrate 22, which can improve the positioning accuracy of the substrate 22 and the sub-holder 20. Since the base plate 22 covers all regions of the holder body 31 except the longitudinally extending portion 31c in a state where the protrusion 312 of the holder body 21 is fitted in the groove portion 222 of the base plate 22, the battery base plate terminals 32c, 32d, the switch base plate terminal 33c, and the buzzer base plate terminals 34c, 34d, which extend from the laterally extending portions 31a, 31b and come into contact with the base plate 22 in an assembled state, are covered with the base plate 22, and therefore, for example, a user does not touch these terminals when replacing batteries, and reliability of the product can be improved.
As shown in fig. 2, the substrate 22 is assembled to the back surface side of the sub-holder 20, and the button cell 40 and the buzzer 50 are mounted on the sub-holder 20, thereby completing the assembly of the core of the electronic thermometer 1. Then, a part of the base plate 22 and a part of the holder body 31 of the terminal assembly 30 are pressed from the back side by the retainer 23, and the component parts of the electronic thermometer 1 assembled integrally are loaded into the front case 11a from the rear end opening of the cylindrical front case 11a together with the retainer 23, and the retainer 23 is made to reach the inside of the front case 11 a. In this state, the rear housing 11b and the front housing 11a are folded, and the screw holes of the positioner 23 are screwed by the fixing screws 24 through the holes of the rear housing 11b and the front housing 11 a. Finally, the temperature measuring unit 12 is attached to the front end of the front sub-mount 11a, and the temperature measuring unit 12 is connected to the substrate 22 via the lead wire 25.
The positioner 23 includes positioning pins 234 corresponding to the positioning holes 224 on the substrate 22, and performs mutual positioning of the substrate 22, the auxiliary stand 20, and the components thereof.
In a state where the respective components are mounted on the front and rear cases 11a and 11b together with the retainer 23, the retainer 23 presses the projection 312 of the holder body 31, thereby adjusting the pressure against the buzzer 50.
Fig. 9 is a perspective view of a structure related to the buzzer 50 in the electronic thermometer 1 according to the embodiment of the present invention.
As shown in fig. 3 and 9, in the present embodiment, a U-shaped notch 235 penetrating through a rear surface side wall portion of the retainer 23 is formed at a portion where the retainer 23 abuts against the boss portion 312 of the holder body 31, so that a biasing spring 236 is formed inside the U-shaped notch 235, and the pressing force applied to the buzzer 50 by the holder body 31 can be easily adjusted by abutting the biasing spring 236 against the boss portion 312.
According to the above embodiment of the present invention, the positive terminal, the negative terminal, the switch terminal of the button cell 40, the positive terminal, the negative terminal of the buzzer 50, and the substrate terminal are integrated into one component of the terminal assembly 30, and functions that would otherwise be realized by more than 3 components are realized by one component of the terminal assembly 30.
During assembly, all the terminals are mounted only by clamping and fixing the terminal assembly 30 and the auxiliary bracket 20, so that the production efficiency is greatly improved.
Because the number of parts is reduced, the assembly process is reduced, uncontrollable factors are reduced, the occurrence of poor contact is greatly inhibited, the yield is improved, and the product cost is reduced.
Since the terminal assembly 30 occupies a small space, it is advantageous for miniaturization of the product.
The present embodiment has been described in detail with reference to an electronic thermometer as an example, but the present invention is not limited to the electronic thermometer, and the present invention is also applicable to various small electronic devices.
In the above embodiment, only one button cell is provided, but the present invention is not limited thereto, and a plurality of button cells may be provided.
While the preferred embodiments of the present invention have been described in detail, the present invention is not limited thereto, and those skilled in the art can make various modifications to the present invention without departing from the scope of the present invention.
