  When the slide switch 5 shown in FIG. 6 or the slide switch installed in Patent Document 1 is used, the shape of the main body of the voltage detector (for example, the cylindrical main body 2 in FIG. 5) is also affected by the size. As a result, not only is the degree of freedom in design limited, but there is also a disadvantage that the cost of parts increases.

  Also, when the slide switch is a rebound switch similar to the push switch, the signal is sent to the internal circuit only when the slide switch is slid, and the circuit is turned on and off electronically. However, there was also a problem that even though the amount was small, the current flowed and the battery was consumed.

  The present invention provides various battery devices with a power switch that can reduce the cost of components while increasing the degree of freedom in design and at the same time eliminate the minute consumption of the battery when the circuit is OFF. The purpose is to do.

The main feature is that a conductive metal piece is provided so as to freely control electrical contact and separation between the other electrode and the other electrode plate.

  In this case, it is preferable that the other electrode of the battery is a plus electrode, and the conductive metal piece provided in the lid-like switch portion is arranged so as to allow only contact with the plus electrode.

  According to the present invention, by eliminating the slide switch that opens and closes the electric circuit from various battery devices, the design freedom on the main body side can be increased, and the cost of parts can be reduced by simplifying the switch structure. Can be reduced. In addition, when the battery is not used, the battery can be completely cut off between the positive electrode and the negative electrode, so that a small amount of battery consumption can be eliminated. Furthermore, when the conductive metal piece provided in the lid-like switch part is arranged so as to be able to contact only with the positive electrode of the battery, damage to the detection circuit part due to erroneous battery loading can be surely prevented. Can do.

FIG. 6 is an enlarged perspective view showing the details of the internal structure of the lid-like switch part 62 formed so as to correspond to the sides separately, changing the viewing position thereof.

  According to these figures, the main body portion 22 has a flange portion 29 provided around the outer peripheral surface 22b positioned slightly below the position of the top end edge 28a and having a larger diameter than the outer diameter of the main body portion 22 itself. An intermediate outer peripheral portion 30 secured to the upper portion of the main body portion 22 at a portion continuous with the flange portion 29 via a stepped surface 29a and having an approximately same diameter as that of the main body portion 22, and the intermediate outer peripheral portion 30. The top end portion 28 is formed of a small-diameter outer peripheral portion 31 provided at a portion continuous to the top end edge 28a via the step surface 30a.

  The lid-like switch part 62 applied to the top end part 28 side of the main body part 22 is integrally formed with, for example, a circular top plate part 63 and a peripheral wall part 65 suspended from the top plate part 63. At the time of covering, the contact with the stepped surface 29a of the flange portion 29 of the cylindrical main body portion 22 can be freely made through the open end surface 65a of the peripheral wall portion 65. In addition, the code | symbol 89 in a figure shows the uneven | corrugated | grooved part for performing a rubbing operation smoothly.

  Moreover, the inner peripheral surface 66 of the peripheral wall portion 65 in the lid-like switch portion 62 can be matched with the movement required between the intermediate outer peripheral portion 30 and the small-diameter outer peripheral portion 31 at the top end portion 28 of the main body portion 22. It is formed by adding an internal structure.

  That is, when the relationship between the top end portion 28 of the main body portion 22 and the lid-like switch portion 62 applied to the top end portion 28 is specifically described according to the illustrated example, the small-diameter outer peripheral portion 31 at the top end portion 28 of the main body portion 22 is appropriately used. At the position, the plate-like main body portion 56 of the positive electrode plate 55 is exposed so as to protrude from the outer peripheral surface 22b so that the contact portion 57 attached with elasticity to the open end side is opened, and the contact portion 57 is opened. A notch window 32 having a shape for supporting the edge 57a side from the back side is formed.

  Further, in the small-diameter outer peripheral portion 31, protrusions 33 are provided separately on the top edge 28 a side in the vicinity of the left side of the notch window 32 and the opposite position in the circumferential direction. Further, a pair of ridges 34, 34 parallel to the vertical direction are provided at each position on the intermediate outer peripheral portion 30 below the notch window 32 and on the opposite side in the circumferential direction. Positioning recesses 35 are formed between the ridges 34, 34, respectively. Furthermore, the current position of the lid-like switch part 62 that is covered is recognized at both parts of the collar part 29 that are located below the notch window 32 and spaced slightly apart in the left-right direction. The standby position mark 36 and the energization position mark 37 are provided separately from each other. Note that the standby position mark 36 and the energization position mark 37 are arranged by an appropriate method such as engraving or drawing as long as the current position of the lid-like switch unit 62 can be recognized. be able to.

  On the other hand, the inner peripheral surface 66 of the peripheral wall portion 65 in the lid-like switch portion 62 is on the outer peripheral surface 22b on the top end portion 28 side of the main body portion 22 when the lid is applied, A large-diameter inner peripheral portion 67 that faces the small-diameter outer peripheral portion 31 that is continuous with the intermediate outer peripheral portion 30 and a small-diameter inner peripheral portion 70 that faces each other.

  Among these, the large-diameter inner peripheral portion 67 is formed with an inner diameter that allows the introduction of the small-diameter outer peripheral portion 31 including the projections 33 at the top end portion 28 of the main body portion 22, and also during standby and contact closing. A total of two small projections 68 that are freely arranged to be fitted with the positioning recess 35 in two stages with respect to time are provided separately at sites that are in a positional relationship facing each other in the circumferential direction. Further, each position of the outer peripheral surface 62a of the lid-like switch part 62 located between the adjacent small protrusions 68, 68 is aligned by the relationship between the standby position mark 36 and the energized position mark 37, for example, in the form of a protrusion. An alignment mark 69 is provided. The alignment mark 69 can be provided by an appropriate method such as engraving or drawing other than the illustrated example.

  Furthermore, the large-diameter inner peripheral portion 67 abuts on the ridge 34 at a position adjacent to the one ridge 34 when the lid is applied, and prevents the lid-like switch portion 62 from rotating more than necessary. A projection 72 is provided.

  A small-diameter inner peripheral portion 70 that is in a positional relationship facing the small-diameter outer peripheral portion 31 of the main body portion 22 at the time of covering is an introduction groove portion 71a that permits the introduction of the protruding portion 33 provided in the small-diameter outer peripheral portion 31 as shown in FIG. A narrow groove 71b that guides the protrusion 33 until it reaches a standby position mark 36 that indicates a standby time when the circuit is opened continuously with the introduction groove 71a, and a circuit that is closed with the narrow groove 71b. A guide groove 71 including a wide groove 71c for guiding the protrusion 33 to the energized position mark 37 thus formed is provided.

  For this reason, the lid-like switch portion 62 has an open end surface 65a that is substantially in close contact with the step surface 29a of the flange portion 29 of the main body portion 22 when the projection portion 33 enters the narrow-width groove portion 71b through the introduction groove portion 71a. When the negative electrode contact 54 energizes the battery B in the pushing direction when it enters the wide groove 71c through the narrow groove 71b, the groove between the wide groove 71c and the narrow groove 71b. A gap t having only a width difference is formed and extruded as shown in FIG.

  Further, as shown in FIG. 4C, the lid-like switch portion 62 is provided with a conductive metal piece 83 via an inner surface 63a of the top plate portion 63 and an inner peripheral surface 66 of the peripheral wall portion 64. The top end portion 28 is biased in the pushing direction by the spring force generated by the conductive metal piece 83 by the contact portion 57 on the positive electrode plate 55 side and the negative electrode contact 54 provided in the voltage detection circuit body 52. The positive electrode p, which is the other electrode of the battery B accommodated so as to slightly protrude from the top end edge 28a, can be short-circuited.

  That is, the conductive metal piece 83 includes a horizontal piece 84 having an appropriate width that spans the longest part of the inner surface 63a of the top plate 63, and the peripheral wall 65 of the lid-like switch part 62 from both ends of the horizontal piece 84. The inner peripheral surface 66 is formed of upright pieces 88 each provided with a length that is at least about the vertical dimension of the small-diameter inner peripheral portion 70 and made to stand upright separately.

  In this case, a convex contact 85 that can freely come into contact with the positive pole p of the battery B, as is apparent from FIG. In addition to projecting in the upright direction of the portion 88, a cutout portion 86 is formed in each portion located on both sides in the length direction of the convex contact 85 to form the convex contact 85 direction from the base end 87 a side. The fixing claw pieces 87 formed by standing up and cutting off the tip portion by an appropriate length are individually formed in an arrangement relationship facing each other.

  Further, on the inner side surface 63a of the top plate portion 63 facing the portion located near the convex contact 86 of each notch portion 86, as shown in FIG. 4 (c), a horizontal piece portion 84 toward the top plate portion 63 side. The fixing projections 64 that project with the open edges 87b of the fixing claw pieces 87 when the is pressed are provided separately. In this case, if the seating height of each fixing protrusion 64 is formed higher than the protruding height of the convex contact 85, the convex shape is provided even when the battery B is reversely loaded and the negative pole m is located. It can also function as an obstacle that prevents contact with the contact 85.

  Next, the operation and effect of the present invention having the above configuration will be described with reference to FIGS. 1 to 4. In the main body portion 22, the front end portion 53 a side of the detection circuit portion 53 protrudes from the tip end portion 23, and The negative pole contact 54 comes into contact with the negative pole m of the battery B, and the contact portion 57 attached to the plate-like main body portion 56 of the positive electrode plate 55 is connected to the cutout window of the small-diameter outer peripheral portion 31 at the top end portion 28 of the main body portion 22. The voltage detection circuit body 52 is disposed under the state of being exposed from 32.

  The cap part 42 is fastened by being fitted to the front end part 23 side of the main body part 22 in order to cover and protect the front end part 53a side of the detection circuit part 53 of the detection circuit body 52.

  A battery B composed of two dry batteries is loaded in series in the main body 22 in such a positional relationship that the negative pole m faces the negative pole contact 54 side. At this time, the plate-like main body portion 56 of the positive electrode plate 55 is insulated from the battery B because it includes the insulating layer 56a on the inner side (the surface facing the battery B).

  After the battery B is loaded in the main body 22 in this way, the lid-like switch portion 62 is covered on the top end portion 28. The lid covering procedure at that time will be described in detail. Each introduction groove portion of the small-diameter inner peripheral portion 70 in the lid-like switch portion 62 is provided in each projection portion 33 protruding from the small-diameter outer peripheral portion 31 in the top end portion 28 of the main body portion 22. The lid-like switch portion 62 is pushed into the top end portion 28 side of the main body portion 22 under the positional relationship in which the 71a faces each other.

  The lid-like switch part 62 permits the introduction of the projections 33 on the main body part 22 side through the introduction groove parts 71a in the guide groove 71. As a result, the open end face 65a has a stepped surface 29a of the flange part 29 on the main body part 22 side. To come into contact.

  At this time, by rotating the lid-like switch part 62 in the clockwise direction, each projection 33 on the main body part 22 side is introduced into each narrow groove 71b in the guide groove 71, and as a result, the lid-like switch part. 62 is also prevented from falling off and is covered with the main body 22 side. Thereafter, the positive electrode p of the battery B is always in contact with the convex contact 85 provided on the horizontal piece 84 of the conductive metal piece 83. In addition, when the seating height of each fixing projection 64 projecting from the inner side surface 63a of the top plate portion 63 is formed higher than the projecting height of the convex contact 85, the battery B is reversely loaded. Therefore, even if the negative pole m is located, it can function as an obstacle that prevents the contact with the convex contact 85, so that damage to the detection circuit unit 53 due to erroneous loading of the battery B can be reliably prevented. Will be able to.

  In this state, the lid-like switch portion 62 is further rotated in the clockwise direction so that the alignment mark 69 matches the position of the standby position mark 36 of the main body portion 22, so that each projection 33 on the main body portion 22 side is guided. The groove 71 is introduced into each wide groove 71c. As a result, the lid-like switch portion 62 has a gap t (see FIG. 5) that is the difference in groove width between the wide groove portion 71c and the narrow groove portion 71b due to the pressing force in the pushing direction in which the negative electrode contact 54 is biased to the battery B. 5), the standby state is entered.

  In actual use, the cover-like switch part 62 is further rotated in the clockwise direction, and its alignment mark 69 is aligned with the position of the energization position mark 37 of the main body part 22 as shown in FIG. One standing piece 88 of 83 comes into contact with the contact portion 57 on the positive electrode plate 55 side exposed from the cutout window 32 of the small-diameter outer peripheral portion 31 at the top end portion 28, and the power is turned on to detect the detection circuit portion. 53 is in an energized state and can enter a necessary voltage detection operation.

  After the work is completed, the lid-like switch part 62 can be rotated counterclockwise until the alignment mark 69 coincides with the position of the standby position mark 36 of the main body part 22 so as to be in the previous standby state. Further, when the battery B is replaced, the lid-like switch portion 62 is further rotated counterclockwise so that the projections 33 of the small-diameter outer peripheral portion 31 are returned to the introduction groove portions 71a of the lid-like switch portion 62. The covered state can be eliminated.

  The above description is an example in which the present invention is applied to a voltage detector. However, the application device of the present invention is not limited to this, and a battery is built in the main body and the lid is formed. It can be applied as a power switch structure for various battery devices including a measuring instrument provided with a switch function.
