The battery 4 is attachable to and detachable from the main body 1. In the present embodiment, the battery 4 can be attached to and detached from the main body 1 without using a tool or the like. For example, the battery 4 is attached to the main body 1 when a user of the electric device VC uses the electric device VC, and is detachable from the main body 1 when the electric device VC is not used or is charged. The controller 3 is set with the setting unit 5 to turn on and off the operation of the motor 2. In the present embodiment, the electric appliance VC is an electric appliance for dust collection or an electric vacuum cleaner in which the motor 2 is provided in an electric blower and dust is sucked and collected by the operation of the motor 2. However, the electric device VC is not limited to this, and can be applied to various electric tools using the motor 2.
In the illustrated example, the body 1 is formed in an elongated shape. The housing of the main body 1 is constituted by a main body case 10. The main body case 10 is formed of, for example, synthetic resin. The motor 2 and the control unit 3 are housed inside the main body case 10. A main body suction port 11 for sucking dust-containing air is formed in the main body 1. A dust suction head 7 such as an extension pipe 6 serving as a straight pipe portion of an air passage body or an air passage body suction port body is detachably connected to the main body suction port 11. Further, the main body 1 is provided with a dust collecting unit 12 for collecting dust in the dust-containing air sucked through the main body suction port 11. The dust collecting part 12 may be a dust collecting device such as a dust cup that can be attached to and detached from the main body 1, or may be a dust bag, a filter, or the like that is disposed inside the main body 1. Further, the main body 1 is formed with a main body discharge port 13 through which air from which dust has been separated is discharged. In addition, the electric appliance VC is, for example, a hand-held electric vacuum cleaner that performs a vacuum cleaning operation by gripping the main body 1. Therefore, in the present embodiment, the main body 1 is formed with a grip portion 14 to be gripped by a user. In the illustrated example, the setting unit 5 is disposed in the grip portion 14.
As shown in fig. 4, a battery detachable portion 15 for attaching and detaching the battery 4 is formed in the main body portion 1. In the present embodiment, the battery detachable portion 15 is provided recessed outside the main body portion 1. The battery detachable portion 15 is located outside the main body case 10 and can be visually observed in a state where the battery 4 is detached. Further, by the attachment of the battery 4, a part of the battery detachable portion 15 is shielded by the battery 4. That is, in the present embodiment, the battery 4 is externally attached to the main body 1. The battery mounting portion 15 is located at an end portion of the main body portion 1.
Hereinafter, for clarity of explanation, the vertical direction shown in fig. 4 is defined as a vertical direction as a first direction, a direction orthogonal to the vertical direction and along the longitudinal direction of the main body 1 is defined as a front-rear direction as a second direction, and a direction orthogonal to the vertical direction and the front-rear direction is defined as a left-right direction or both directions as a third direction. That is, the direction of arrow D1a, the direction of arrow D1b, the direction of arrow D2a, the direction of arrow D2b, the direction of arrow D3a, and the direction of arrow D3b shown in fig. 3 are upward, downward, forward, rearward, leftward, and rightward. In fig. 1 to 6, the directions of the arrows are shown based on the directions defined in fig. 4. Note that these up-down direction, left-right direction, both-side direction, and front-back direction are used for the present description, and do not indicate the use state or use posture of the electric device VC.
The battery removing portion 15 has an opposing portion 150 that faces the battery 4. The opposing portion 150 forms a part of the main body case 10, and is a wall portion that separates the battery 4 attached to the battery attaching/detaching portion 15 from the inside of the main body case 10. In the present embodiment, the facing portion 150 is formed in a planar shape extending in the front-rear direction and the left-right direction.
The battery mounting portion 15 also has a regulating portion 151 that regulates the position of the battery 4 in the left-right direction with respect to the battery mounting portion 15. The restricting portions 151 are formed to rise from both left and right sides of the facing portion 150 in a wall shape. The restricting portion 151 is formed in an elongated shape along the front-rear direction. Further, a support portion 152 that supports the battery 4 with respect to the main body portion 1 is formed in the regulating portion 151. The support portion 152 supports the battery 4 so as to be hooked to its own weight. The support portion 152 is formed to protrude from the restriction portion 151 toward the center portion in the left-right direction of the battery mounting portion 15. The regulating portion 151 and the supporting portion 152 function as a guide portion for guiding the battery 4 in the attaching and detaching direction with respect to the main body portion 1. In the present embodiment, the battery 4 is attached to the battery attaching/detaching portion 15 of the main body portion 1 by sliding in the front-rear direction from the rear to the front, and detached by sliding in the front-rear direction from the front to the rear. In the illustrated example, the battery 4 is attached to and detached from the battery attaching/detaching portion 15 of the main body portion 1 in the front-rear direction.
The battery 4 attached to the battery detachable portion 15 is detachably locked to the battery detachable portion 15 or the main body portion 1 by the locking portion 153. In the present embodiment, the locking portion 153 is a gripper that is operated by a user. The locking portion 153 includes a locking claw portion 1530 located at the battery removing portion 15 and an operated portion 1531 located outside the battery removing portion 15.
The locking claw portion 1530 is biased in a direction to lock the battery 4 by a locking biasing mechanism which is an elastic body such as a spring. In a state where the battery 4 is mounted on the battery mounting portion 15, the locking claw portion 1530 is inserted into and locked to the locking receiving portion of the battery 4 to lock the battery 4, and is covered by the battery 4 so as not to be exposed in the external appearance.
The operated portion 1531 is operated by the user to retract the locking claw portion 1530 from the locking receiving portion of the battery 4 against the biasing force of the locking biasing mechanism.

As shown in fig. 3 and 4, battery detaching unit 15 includes a contact mounting unit 16 for electrically connecting battery 4 and control unit 3. In the present embodiment, the contact assembly portion 16 is formed in a unit shape independent from the main body housing 10. In the illustrated example, the contact assembly portion 16 is attached to an opening 155 formed in the battery attachment portion 15. The contact assembly portion 16 is configured to be easily attached to and detached from the body 1 using a tool or the like without disassembling the body 1. For example, the contact assembly portion 16 is configured to be attachable to and detachable from the main body portion 1 using a fixing body S such as a screw. The opening 155 is formed in a hole shape in the main body case 10. The control unit 3 is located at a position facing the opening 155. That is, at least a part of the control unit 3 can be exposed from the opening 155. In the present embodiment, the opening 155 is located at the distal end of the facing portion 150. The opening 155 is formed to have a predetermined size in the left-right direction. In the present embodiment, the opening 155 is formed in a size that allows an adult finger to be inserted therein. In the illustrated example, the opening 155 is formed over the facing portion 150 and the stopper portion 154. For example, the opening 155 is positioned between the locking claw portions 1530 on both the left and right sides. The contact assembly portion 16 closes the opening 155 in a state of being attached to the opening 155. That is, the contact assembly portion 16 forms a part of the housing of the main body portion 1.
The contact assembly portion 16 includes a contact portion 160 and a mounting portion 161 serving as a mounting base on which the contact portion 160 is mounted.
The contact portion 160 is formed of a conductive metal. The contact portion 160 is made of copper, for example. The contact portion 160 is formed by press working. The contact portion 160 is formed by a plate. The contact portion 160 is formed so that there are no multiple overlapping portions in the thickness direction. In the present embodiment, the contact portion 160 is formed in a flat plate shape without a portion bent in the thickness direction. Further, the contact portion 160 is formed in an elongated shape. The contact portions 160 extend in an elongated shape in a direction intersecting or orthogonal to the thickness direction. In the present embodiment, the contact portion 160 has the longitudinal direction arranged in the front-rear direction and the thickness direction arranged in the left-right direction. The surface of the contact portion 160 may be plated for reinforcement.
The contact portion 160 electrically and mechanically connects the battery 4 and the connected portion 8. The contact section 160 has a first connection section 1600 and a second connection section 1601. As shown in fig. 1, in the present embodiment, the contact portion 160 further includes an intermediate portion 1602 that connects the first connection portion 1600 and the second connection portion 1601 between them.
In the present embodiment, the first connection portion 1600 is a portion at least a part of which is exposed to the outside of the main body 1 or the main body case 10. In the illustrated example, the first connection portion 1600 has a distal end portion and a lower end portion embedded in the mounting portion 161, and the other portions exposed from the mounting portion 161. The first connection portion 1600 is formed in a substantially quadrangular shape. In the present embodiment, the first connection portion 1600 is formed in a rectangular shape that is long in the longitudinal direction of the contact portion 160. The long side size of the first connection portion 1600 is set longer than the long side size of the second connection portion 1601. The length of the first connection portion 1600 is set to be equal to or more than half of the total length of the contact portion 160.
The first connection portion 1600 has substantially a certain or substantially a certain thickness. The first connection portion 1600 is a thick portion having a predetermined thickness. Two surfaces in the thickness direction of the first connection portion 1600 are arranged parallel or substantially parallel to each other. These two surfaces in the thickness direction of the first connection portion 1600 form a planar sliding contact surface 16000 with which the blade receiving portion 40 of the battery 4 is brought into sliding contact. The sliding contact surface 16000 is a conductive surface for electrically connecting the battery 4 and the contact portion 160.
In the present embodiment, a first thin portion 16001 having a gradually reduced thickness toward the distal end side is formed at the rear end portion, which is one end portion, of the first connection portion 1600. That is, the end of the first connection portion 1600 that receives the battery 4 is thinner than the other portions. In the illustrated example, the first connection portion 1600 has a constant or substantially constant thickness in a portion other than the first thin portion 16001.
As shown in fig. 2, the first connection portion 1600 is set to have a larger width in the vertical direction, which is a direction intersecting the thickness direction and the longitudinal direction, than the second connection portion 1601. In the present embodiment, the vertical width of the first connection portion 1600 is set to be larger than the vertical widths of the second connection portion 1601 and the intermediate portion 1602. Therefore, a width varying portion 16002 whose width varies in the vertical direction is formed at the tip end portion of the first connection portion 1600, which is the other end portion. In the present embodiment, the width varying portions 16002 are formed at the upper and lower ends of the front end portion of the first connection portion 1600, respectively. In the illustrated example, the width of the width varying portion 16002 in the vertical direction is abruptly varied to form a stepped shape. The width varying portion 16002 is formed linearly along the vertical direction. In the present embodiment, the width-varying portion 16002 is formed at a position where the first connection portion 1600 is connected to the intermediate portion 1602. The direction and angle of width-varying portion 16002 are set so as not to deform contact portion 160 by the attachment of battery 4 to first connection portion 1600 shown in fig. 1.
As shown in fig. 2, the first connection portion 1600 has four curved portions 16003 curved in an arc shape at four corners when viewed in the thickness direction. Thus, the first connection portion 1600 is formed so as not to generate a convex corner portion when viewed in the thickness direction. The ridge line of the first connection portion 1600, the portion of the first connection portion 1600 constituting the outer edge portion when viewed in the thickness direction, or the left and right side edge portions of the upper end portion and the lower end portion of the first connection portion 1600 are formed in a rounded shape or a chamfered shape curved in an arc shape in the thickness direction, respectively, so that no corner portion or edge occurs. Therefore, the first connection portion 1600 is formed so that electric field concentration is less likely to occur at four corners and ridge lines when viewed in the thickness direction.
The second connection portion 1601 forms a distal end portion side, which is the other end portion side in the longitudinal direction of the contact portion 160. The second connection portion 1601 is a portion electrically connected to the control portion 3 via the connected portion 8 shown in fig. 3. In the present embodiment, the connection target portion 8 is directly disposed on the control portion 3. The connected portion 8 can be directly accessed from the opening 155. For example, as shown in fig. 5, the connection portion 8 is directly attached to the control portion main body 30, which is a plate-shaped substrate of the control portion 3. In addition to the control unit main body 30, various elements 31 are mounted to constitute a control circuit. The connection target portion 8 is provided with, for example, a conductive terminal portion 8a and a terminal receiving portion 8b as a housing of a terminal such as a crimp terminal. In the illustrated example, the terminal portions 8a and the terminal receiving portions 8b are arranged in a row along the short-side direction at one end portion in the long-side direction of the control unit main body 30. The connection target portion 8 is not limited to being disposed directly on the control portion 3, and may be disposed at a position independent from the control portion 3.
As shown in fig. 1 and 2, a lead wire 9 is electrically and mechanically connected to the second connection portion 1601. The lead wire 9 may be electrically and mechanically detachably connected to the second connection portion 1601 by using a terminal 90 such as a crimp terminal typified by a fston terminal, or may be directly electrically and mechanically connected to the second connection portion 1601 by soldering or the like. In fig. 1, for clarity of explanation, the terminal 90 is shown only for the second connection portion 1601 of 1 contact portion 160.
In the present embodiment, the second connecting portion 1601 is a portion housed inside the main body portion 1 or the main body case 10 shown in fig. 3. As shown in fig. 1 and 2, the second connection portion 1601 is formed in a substantially rectangular shape. In the present embodiment, the second connection portion 1601 is formed in a rectangular shape that is long in the longitudinal direction of the contact portion 160. The second connection portion 1601 has substantially a certain or substantially certain thickness. The second connection portion 1601 is a thin portion having a predetermined thickness smaller than the first connection portion 1600. In the present embodiment, a second thin portion 16010 having a gradually reduced thickness toward the distal end side is formed at the distal end portion, which is the other end portion, of the second connecting portion 1601. In the illustrated example, the second connection portion 1601 has a hole portion that penetrates in the thickness direction, that is, a holding portion 16011. The holding portion 16011 is a portion for engaging with the protrusion of the terminal 90 to hold the terminal 90 when the lead wire 9 is connected to the terminal 90. The holding portion 16011 is a portion into which the leading end portion of the lead wire 9 is inserted and coupled when the lead wire 9 is soldered to the second connection portion 1601. The ridge line of the second connecting portion 1601, the portion of the second connecting portion 1601 constituting the outer edge portion when viewed in the thickness direction, or the left and right side edge portions of the upper end portion and the lower end portion of the second connecting portion 1601 are preferably formed in a rounded shape or a rounded chamfered shape curved in an arc shape in the thickness direction, respectively, so that no corner or edge is generated.
The intermediate portion 1602 is a portion that integrally connects the first connection portion 1600 and the second connection portion 1601. The middle portion 1602 is set to have a thickness equal to or substantially equal to that of the first connection portion 1600 at a rear end portion side as one end portion side connected to the first connection portion 1600, and set to have a thickness equal to or substantially equal to that of the second connection portion 1601 at a front end portion side as the other end portion side connected to the second connection portion 1601. Therefore, a thickness variation part 16020 having a varying thickness is formed between both end parts of the intermediate part 1602. The thickness varying portion 16020 is preferably formed as an inclined surface whose thickness gradually decreases from the rear end portion side, which is one end portion, of the intermediate portion 1602 to the front end portion side, which is the other end portion. Further, at least a portion of the thickness variation 16020 that is convex in the thickness direction is formed in a rounded shape or a rounded chamfered shape that is curved in an arc shape. Preferably, the position where the thickness variation part 16020 is connected to the first connection part 1600 is formed in a rounded shape or a chamfered shape curved in an arc shape, and is formed so that no corner or edge is generated. More preferably, the position where the thickness variation part 16020 is connected to the second connection part 1601 is formed in a rounded shape or a chamfered shape curved in an arc shape, and is formed so that no corner or edge is generated. Therefore, the contact 160 is formed so that a step portion or a corner portion whose thickness changes abruptly does not occur from the first connection portion 1600 to the second connection portion 1601. Therefore, the contact portion 160 is formed so that electric field concentration due to a difference in thickness between the first and second connection portions 1600 and 1601 is not easily generated at a position therebetween. The thickness variation part 16020 is formed to be symmetrical or substantially symmetrical with respect to the thickness direction. The intermediate portion 1602 is formed to have a uniform or substantially uniform thickness in the thickness direction by the thickness varying portion 16020. Therefore, in the contact portion 160, heat generated when the lead wire 9 is soldered to the second connection portion 1601 is uniformly dispersed to the left and right.
At least a part of the intermediate portion 1602 is embedded in the mounting portion 161. In the present embodiment, the rear end portion side of the intermediate portion 1602 connected to the first connection portion 1600 is embedded in the mounting portion 161. In the illustrated example, the middle portion 1602 is embedded in the mounting portion 161 at a portion on the rear side of the front end portion of the variable thickness portion 16020. Thus, the contact portion 160 is attached to and embedded in the attachment portion 161 at a position having a thickness larger than that of the second connection portion 1601.
The vertical width of the intermediate portion 1602 is set larger than the second connection portion 1601. In the present embodiment, the width of the intermediate portion 1602 in the vertical direction is set to be smaller than the first connection portion 1600 and larger than the second connection portion 1601. Therefore, an intermediate width varying portion 16021, which varies in width in the vertical direction, is formed at the tip end portion of the intermediate portion 1602, which is the other end portion. In the present embodiment, the intermediate width varying portion 16021 is formed at each of the upper and lower ends of the front end portion of the intermediate portion 1602. That is, the intermediate width varying portion 16021 is formed at a position where the intermediate portion 1602 and the second connecting portion 1601 are connected. In the present embodiment, the intermediate width varying portion 16021 is located at a position exposed forward from the mounting portion 161. In the illustrated example, the width of the intermediate width varying portion 16021 in the vertical direction is abruptly varied to form a stepped shape. The intermediate width varying portion 16021 is formed linearly in the vertical direction. The intermediate width varying portion 16021 functions as a stopper for the terminal 90 of the wire 9. It is preferable that the ridge line of the intermediate portion 1602, the portion constituting the outer edge when the intermediate portion 1602 is viewed in the thickness direction, or the left and right side edge portions of the upper end portion and the lower end portion of the intermediate portion 1602 are each formed in a rounded shape or a chamfered shape curved in an arc shape so that no corner or edge is formed.
In the present embodiment, a plurality of contact portions 160 are provided. These contact portions 160 are separated from each other at predetermined intervals in the left-right direction. The distance between the contact portions 160 in the left-right direction is set to be constant or substantially constant. In the illustrated example, 4 contact portions 160 are provided. Preferably, the contact portions 160 are set in pairs. For example, two pairs of contact portions 160 are set. One pair of contact portions 160a is a high-power contact portion, a high-voltage contact portion, or a large-current contact portion for power supply, and the other pair of contact portions 160b is a low-power contact portion, a low-voltage contact portion, or a small-current contact portion for signal or information communication. The contact portion 160a is set to have a slightly longer overall length, a larger thickness of the second connection portion 1601, and a larger vertical width of the second connection portion 1601, compared to the contact portion 160 b. For example, the first connection portions 1600 of the contact portions 160a and 160b are each set to a thickness of 1.0mm or more, the second connection portions 1601 of the contact portion 160a are set to a thickness of about 0.8mm, and the second connection portions 1601 of the contact portion 160b are set to a thickness of about 0.5 mm. In the present embodiment, the contact portions 160a are disposed near both sides of the mounting portion 161, and the contact portions 160b are disposed between the contact portions 160 a.
In the example shown in fig. 5, the contact portion 160a is electrically and mechanically detachably connected to the terminal portion 8a in the connected portion 8. The contact portion 160b is electrically and mechanically detachably connected to the terminal receiving portion 8b in the connected portion 8.
One of the contact portions 160a is a power feeding contact portion, an anode contact portion, or a high-side contact portion, and the other is a ground contact portion, a cathode contact portion, or a low-side contact portion. In the example shown in fig. 1, the contact portion 160a1 located on the arrow D3b side is a cathode contact portion or a low-side contact portion, and the contact portion 160a2 located on the arrow D3a side is an anode contact portion or a high-side contact portion. The contact portion 160a1 is located on the rear side of the first connection portion 1600 in the mounting direction of the battery 4 with respect to the contact portion 160a 2. Therefore, when the battery 4 is mounted, the contact 160a1 is arranged to contact the blade receiving portion 40 of the battery 4 at a timing before the contact 160a 2. In fig. 1, the first connection portion 1600 of the contact portion 160a1 extends toward the rear side with respect to the first connection portion 1600 of the contact portion 160a 2.
The contact portion 160 is attached to the attachment portion 161. In the present embodiment, the contact portion 160 is fixed to the mounting portion 161. In the example shown in fig. 4, the mounting portion 161 is a portion that closes the opening 155 in a state where the contact assembly portion 16 is mounted to the battery assembly portion 15 of the main body portion 1. The mounting portion 161 is configured to have an outer shape according to the shape of the opening 155.
As shown in fig. 2, the mounting portion 161 has a first portion 1610 and a second portion 1611.
The first portion 1610 is located at a lower side with respect to the contact portion 160. In the present embodiment, the first portion 1610 supports the contact portion 160. As shown in fig. 4, the first portion 1610 is disposed along the opposing portion 150 of the battery detachable portion 15 in a state where the contact assembling portion 16 is attached to the battery detachable portion 15 of the main body portion 1. In the present embodiment, the first portion 1610 is formed in an elongated shape along the left-right direction. As shown in fig. 1, the contact portions 160 are arranged on the first portion 1610. The upper portion of the first portion 1610 is a first battery facing portion that faces the battery 4 mounted to the main body portion 1.
As shown in fig. 2, a first groove 16100 into which the lower end of the first connection portion 1600 of the contact portion 160 is fitted is formed in the first portion 1610 in the front-rear direction. As shown in fig. 3 and 4, an end surface 16101, which is an outer edge surface of an end of the first portion 1610 located on the opposite side of the second portion 1611, abuts an edge of the opening 155 in a state where the contact assembly portion 16 is attached to the battery assembly portion 15 of the main body portion 1. In the present embodiment, the end surface portion 16101 is located at the rear end portion of the first portion 1610.
The second portion 1611 is a vertical wall portion formed upright from an end of the first portion 1610. In the present embodiment, the second portion 1611 is formed to stand from the front end portion of the first portion 1610. Therefore, as shown in fig. 2, the mounting portion 161 is formed in an L-shaped cross section. As shown in fig. 1, the contact portions 160 are arranged in a row at the rear of the second portion 1611. The rear portion of the second portion 1611 is a second battery facing portion that faces the battery 4 mounted to the main body portion 1. A front end of the first connection portion 1600 is embedded in the rear portion of the second portion 1611. As shown in fig. 4, the second portion 1611 is disposed upright at a position forward of the stopper portion 154 of the battery removing portion 15 in a state where the contact removing portion 16 is attached to the battery removing portion 15 of the main body portion 1.
As shown in fig. 2, the contact 160 is inserted through the second portion 1611. In the present embodiment, second groove 16110 into which the tip of contact 160 is fitted is formed in second portion 1611, and hole 16111 into which contact 160 is inserted is formed in second groove 16110. The second slot 16110 communicates with the first slot 16100 of the first portion 1610. The hole 16111 is formed in the center of the second groove 16110. In the present embodiment, the intermediate portion 1602 of the contact portion 160 is inserted into the hole portion 16111, and the vertical width of the hole portion 16111 is smaller than the vertical width of the first connection portion 1600 of the contact portion 160. Therefore, in the second groove 16110, contact receiving portions 16112, which are retaining portions for retaining and retaining the contacts 160, are formed on both sides of the hole 16111. In the illustrated example, the contact receiving portion 16112 faces the width varying portion 16002 of the contact portion 160, and the tip end portion of the width varying portion 16002 is brought into contact therewith. Therefore, the contact part 160 is restricted in position by the contact receiving part 16112 abutting against the width varying part 16002. In the present embodiment, the position in front of the contact portion 160 is restricted. That is, the contact portion 160 is limited in position on the front side in the mounting direction of the battery 4. Further, by contact receiving portion 16112 abutting width varying portion 16002, vibration or impact at the time of connecting battery 4 to first connection portion 1600 is received by mounting portion 161 via contact receiving portion 16112.
As shown in fig. 3 and 4, an end surface 16113, which is an outer edge surface of the second portion 1611 opposite to the first portion 1610, abuts an edge of the opening 155 at a position above the contact 160. In the present embodiment, the end surface portion 16113 is located at the front upper end portion of the second portion 1611. In addition, at the end surface 16113, a contact locking portion 161130 is formed to lock the contact assembling portion 16 to the main body 1. As shown in fig. 5, in the present embodiment, the contact locking portion 161130 is formed as a long groove portion along the left-right direction. In the example shown in fig. 3, contact locking portion 161130 is held by hooking into holding portion 1550 formed at the edge of opening 155.
Preferably, the mounting portion 161 is molded from synthetic resin. As one example, the mounting portion 161 is molded from a thermoplastic resin. More preferably, the mounting portion 161 is integrally formed with the contact portion 160. For example, in the integral molding of the mounting portion 161 and the contact portion 160, a molding method such as two-color molding or insert molding is used. In this case, the first groove 16100, the second groove 16110, and the hole 16111 of the mounting portion 161 shown in fig. 2 are formed by the contact portion 160.
As shown in fig. 1 and 3, in the present embodiment, the attachment portion 161 includes a fixed portion 1612 for detachably fixing the attachment portion 161 to the body portion 1. In the illustrated example, the fixed portion 1612 extends toward the rear of the first portion 1610. The fixed portion 1612 protrudes rearward from the end surface portion 16101. The fixed portion 1612 has a fixed hole portion 16120. The fixing hole 16120 penetrates the fixed portion 1612 in the vertical direction. Fixing body S is inserted into fixing hole 16120. As an example, the fixing body S is a screw or the like.
The fixed portion 1612 is fitted to a fitting portion 1500 formed in the battery detachable portion 15 of the main body portion 1. The fitting portion 1500 is formed continuously with the edge portion of the opening 155. The fitting portion 1500 is formed with a fixture receiving portion 15000 for fixing the fixture S inserted into the fixing hole 16120. In the present embodiment, the fixing body receiver 15000 is a fastening hole for fastening the fixing body S, for example.
Next, the operation of embodiment 1 will be explained.
The contact portion 160 is formed by press-molding a plate material such as a conductive metal plate. For example, the contact portion 160 is formed by pressing a plate material having a thickness equal to or substantially equal to that of the first connection portion 1600 in the thickness direction to form the second connection portion 1601 and the intermediate portion 1602, which are smaller in thickness than the first connection portion 1600.
In manufacturing the contact assembly portion 16, the contact portion 160 is integrally molded with the mounting portion 161 by providing the contact portion 160, which is molded in advance, in a mold and injection-molding synthetic resin. Thereby, the contact portion 160 is firmly fixed to the mounting portion 161.
The manufactured contact assembly portion 16 is mounted on the main body portion 1. The main body 1 is assembled with the motor 2, the control unit 3, and the like in advance, and necessary wiring is implemented. In the present embodiment, as shown in fig. 3, a part of the control unit 3 is exposed from the opening 155, and the connected unit 8 attached to the control unit 3 is accessible from outside the opening 155. Therefore, after the lead wire 9 connected to the connection target portion 8 in advance is led out from the opening 155, and the lead wire 9 is connected to the second connection portion 1601 of the contact portion 160 of the contact assembly portion 16 via the terminal 90 or the like, the lead wire 9 is pushed into the main body portion 1 from the opening 155, and the contact assembly portion 16 is fitted into the opening 155. At this time, the contact assembly unit 16 hooks the contact locking unit 161130 of the mounting unit 161 to the holding unit 1550 of the main body 1, and causes the end surface portions 16101 and 16113 to abut against the edge of the opening 155, respectively, and causes the fixed portion 1612 to be fitted into the fitting unit 1500. In this state, the opening 155 is covered by the mounting portion 161. Then, by inserting the stator S into the fixing hole 16120 of the mounting portion 161 and fixing it to the stator receiving portion 15000, the contact mounting portion 16 is positioned at the battery mounting portion 15 and easily mounted to the main body portion 1.
When the electric device VC is used, the battery 4 is attached to the battery detachable portion 15 of the main body portion 1. The battery 4 is positioned between the restricting portions 151 on both sides in the rear portion of the battery removing portion 15, and slides forward while engaging both sides with the supporting portions 152, whereby the blade receiving portion 40 is pushed into the first connecting portion 1600 of the contact portion 160 so as to be opposed thereto, electrically connected to the first connecting portion 1600, and locked by the locking claw portion 1530 of the locking portion 153, and attached to the main body portion 1.
The battery 4 is electrically and mechanically connected to the first connection portion 1600 of the contact portion 160, whereby the battery 4 and the control portion 3 are electrically connected via the second connection portion 1601 of the contact portion 160, the lead wire 9, and the connected portion 8. Therefore, power can be supplied from the battery 4 to the motor 2.
When the user operates the setting unit 5, the control unit 3 controls the operation of the motor 2 in accordance with the operation of the setting unit 5. The negative pressure generated by the operation of the motor 2 sucks the dust from the main body suction port 11 into the dust collecting section 12, and the dust is collected by the dust collecting section 12. The air from which the dust is separated and collected cools the motor 2 and is discharged to the outside of the main body 1 from the main body discharge port 13.
According to the embodiment described above, the contact portion 160 is formed as one plate integrally including the first connection portion 1600 mechanically and electrically and detachably connected to the battery 4 and the second connection portion 1601 electrically connected to the connection target portion 8, so that the contact portion 160 can be stably manufactured with fewer unstable elements in manufacturing. Further, since the second connection portion 1601 is formed thinner than the first connection portion 1600, strength that can withstand repeated attachment and detachment of the battery 4 or attachment and detachment at high frequency can be ensured by the thickness of the first connection portion 1600. In particular, when the contact portion 160 is formed of copper which has excellent conductivity but is easily mechanically deformed, the first connection portion 1600 can have a sufficient thickness to secure strength.
On the other hand, since the thickness of the second connection portion 1601 is thinner than that of the first connection portion 1600, a crimp terminal can be used, and caulking deformation, soldering based on improvement of heat conductivity, and the like can be easily performed, so that the degree of freedom of electrical connection with the connected portion 8 can be improved, and stable electrical connection can be realized. Further, since the contact portion 160 is attached to the attachment portion 161, it is possible to suppress transmission of vibration generated by attachment and detachment of the battery 4 to the connected portion 8.
The contact portion 160 is formed with a width changing portion 16002 in which the width thereof changes in a direction intersecting the thickness direction, and the contact portion 160 is positionally regulated with respect to the mounting portion 161 by the width changing portion 16002, whereby the contact portion 160 can be stably fixed with respect to the mounting portion 161, and an impact at the time of mounting the battery 4 to the first connection portion 1600 and the like can be blocked by the width changing portion 16002 and the mounting portion 161 receiving the same, whereby transmission of the impact to the second connection portion 1601 side and vibration caused by the impact can be reduced. Further, since the width varying portion 16002 is formed in the first connection portion 1600 having the largest thickness among the contact portions 160, it is possible to reliably block the impact when the battery 4 is mounted to the first connection portion 1600 in the width varying portion 16002.
By integrally molding the contact portion 160 and the mounting portion 161 made of resin, the contact portion 160 can be firmly fixed to the mounting portion 161, and an impact or vibration caused by the impact when the battery 4 is mounted on the first connection portion 1600 can be more hardly transmitted to the connected portion 8.
Since the contact portion 160 is elongated along the longitudinal direction in the mounting direction of the battery 4, the contact portion 160 can be stably brought into sliding contact with the blade receiving portion 40 of the battery 4 when the battery 4 is mounted.
Further, since the second connecting portion 1601 is electrically connected to the connected portion 8 via the lead wire 9, it is possible to make it more difficult for an impact or vibration caused by the impact to be transmitted to the connected portion 8 when the battery 4 is mounted to the first connecting portion 1600, as compared with a case where the second connecting portion 1601 is directly connected to the connected portion 8.
Since the attachment portion 161 is attachable to and detachable from the opening 155 of the main body 1 in which at least a part of the connection target portion 8 is exposed, the connection target portion 8 exposed from the opening 155 can be easily accessed by detaching the attachment portion 161 from the opening 155. Therefore, by removing the lead wires 9 from the connected portion 8 by inserting a finger from the opening 155, the lead wires 9 can be easily replaced.
In the case of the electric device VC in which at least a part of the first connection portion 1600 of the contact portion 160 is exposed to the outside of the main body portion 1 and the battery 4 is externally mounted on the main body portion 1, since there is a possibility that impact may be applied to the battery 4 from the outside during use, the contact portion 160 and the connected portion 8 can be protected to the greatest extent by the configuration of the present embodiment.
Further, since the mounting portion 161 is fixed to the main body portion 1 from the outside by the fixing body S, if a failure occurs in the contact portion 160, the fixing body S is removed, and when the lead wire 9 is connected to the second connection portion 1601 via the terminal 90, the terminal 90 is removed, whereby the entire contact assembly portion 16 can be easily removed from the main body portion 1 and replaced.
By attaching the contact portion 160 to the attachment portion 161 at a position where the thickness is larger than the thickness of the second connection portion 1601, heat applied to the second connection portion 1601 when the lead wire 9 is soldered to the second connection portion 1601 is diffused by the thickness of the first connection portion 1600 and is not easily transmitted to the attachment portion 161. Therefore, the dissolution of the resin mounting portion 161 due to the heating of the second connection portion 1601 at the time of soldering can be suppressed, and the contact portion 160 can be stably fixed to the mounting portion 161. In particular, when the contact portion 160 is used for high voltage and large current, it is preferable to use a thick lead wire 9, and in this case, when the lead wire 9 is soldered to the second connection portion 1601, it is necessary to sufficiently heat the second connection portion 1601. In this case, since the resin mounting portion 161 is less likely to be dissolved by heating of the second connection portion 1601, the contact portion 160 can be stably fixed to the mounting portion 161, and the second connection portion 1601 can be sufficiently heated, so that a connection failure such as so-called solder failure due to insufficient heating is less likely to occur, and reliability of electrical connection in the contact portion 160 can be improved.
By disposing the first connection portion 1600 of the contact portion 160a1, which is a contact portion for the cathode, of the battery 4 at a position more rearward in the mounting direction of the battery 4 than the first connection portion 1600 of the contact portion 160a2, which is a contact portion for the anode, the cathode side or the ground side can be brought into contact first when the battery 4 is mounted, electric power can be escaped to the ground side when the battery 4 is mounted, and the current sensing prevention function can be operated as a cordless electric appliance VC.
Since the applied voltage and the flowing current are smaller in the signal contact portion 160b than in the power contact portion 160a, the reliability of the electrical connection is not easily deteriorated even if the second connection portion 1601 of the contact portion 160b is formed thinner than the second connection portion 1601 of the contact portion 160 a. Further, the second connection portion 1601 of the contact portion 160b can be made thinner, and therefore the contact assembly portion 16 can be made smaller and lighter.
(embodiment 2)
Next, embodiment 2 will be described with reference to fig. 8. Note that the same components and operations as those of embodiment 1 are denoted by the same reference numerals, and description thereof is omitted.
In the present embodiment, the contact portion 160 has a narrowed portion 1603. The narrow portion 1603 is a portion having a narrow width in a direction intersecting the thickness direction. In the illustrated example, the narrow portion 1603 is a portion having a narrow width in the vertical direction. Further, the narrow portion 1603 is located between the second connecting portion 1601 and the mounting portion 161. That is, the narrow portion 1603 is not embedded in the mounting portion 161 but is exposed to the front of the mounting portion 161. In the present embodiment, the narrow portion 1603 is formed at the rear end portion of the second connecting portion 1601 and is a portion connected to the intermediate portion 1602. In the illustrated example, the narrow portion 1603 is formed by a concave portion 1604 formed by cutting the contact portion 160 in a direction intersecting the thickness direction so as to be continuous with the intermediate width varying portion 16021. In this embodiment, concave part 1604 is formed on each of the upper and lower sides of contact part 160. These concave portions 1604 form air layers adjacent to the narrow portions 1603 above and below.
Since the narrow portion 1603 having a narrow width in the direction intersecting the thickness direction is formed between the second connection portion 1601 of the contact portion 160 and the mounting portion 161, heat applied to the second connection portion 1601 at the time of soldering the lead wire 9 to the second connection portion 1601 is less likely to be transferred to the mounting portion 161. Therefore, the dissolution of the resin mounting portion 161 due to the heating of the second connection portion 1601 at the time of soldering can be suppressed. Further, since narrow portion 1603 is formed by concave portion 1604, heat transfer from second connection portion 1601 to mounting portion 161 can be more reliably suppressed by an air layer formed in concave portion 1604.
In each embodiment, the battery 4 is not limited to being attached to the main body 1 in the front-rear direction, and may be attached to the main body 1 from above toward below, for example. In this case, the contact portion 160 has an elongated shape having a longitudinal direction along a direction intersecting the mounting direction of the battery 4. In the case of such a configuration, the same operational effects as those of the respective embodiments can be exhibited, that is, the degree of freedom of electrical connection with the connection target portion 8 can be improved while securing the strength that can withstand the attachment and detachment of the battery 4, and the transmission of vibration and the like generated by the attachment and detachment of the battery 4 to the connection target portion 8 can be suppressed. Further, since the distance of sliding contact with the blade receiving portion 40 of the battery 4 is short when the battery 4 is mounted, a large force is not easily applied to the contact portion 160, and deformation of the first connection portion 1600 of the contact portion 160 due to mounting can be more reliably suppressed. Therefore, the contact portion 160 can be formed to be further small or thin without making the thickness of the first connection portion 1600 excessively large.
Several embodiments of the present invention have been described, but these embodiments are presented as examples and are not intended to limit the scope of the invention. These new embodiments can be implemented in other various forms, and various omissions, substitutions, and changes can be made without departing from the spirit of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalent scope thereof.
