[Technical Field]

[0001] The present disclosure relates to an attachment for a tester. [Background technology]

[0002] Conventionally, a tester having a first lead rod and a second lead rod is known. The device to be measured for voltage has a pair of voltage measurement terminals. The first lead rod is connected to one of the pair of voltage measurement terminals, and the second lead rod is connected to the other voltage measurement terminal, thereby measuring the voltage between the pair of voltage measurement terminals (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2003-90858 Summary of the Invention [Problem to be solved by the invention]

[0004] The ID controller included in the access control device has a spring-type terminal block to which each of a plurality of wires is connected. The spring-type terminal block has a plurality of wire insertion sections into which each of the plurality of wires is inserted one by one. The plurality of wire insertion sections include a pair of voltage measurement wire insertion sections. The pair of voltage measurement wire insertion sections is a pair of wire insertion sections adjacent to each other and into which no wire is inserted. When maintenance and inspection of the ID controller is performed, the voltage between the pair of voltage measurement wire insertion sections in the ID controller is measured.

[0005] However, in the tester configuration described in Patent Document 1, an operator holds a first lead rod and a second lead rod in each hand, inserts the first lead rod into one of the voltage measurement electric wire insertion portions, and inserts the second lead rod into the other voltage measurement electric wire insertion portion. If there are many wires around the pair of voltage measurement electric wire insertion portions, the operator must move the wires around the pair of voltage measurement electric wire insertion portions while holding a first lead rod and a second lead rod in each hand. This poses a problem in that it is time-consuming to measure the voltage between the pair of voltage measurement electric wire insertion portions in the ID controller.

[0006] The present disclosure has been made to solve the above-mentioned problems, and its purpose is to provide a tester attachment that can easily measure the voltage between a pair of voltage measurement wire insertion portions in an ID controller. [Means for solving the problem]

DETAILED DESCRIPTION OF THE INVENTION

[0010] Embodiment 1 1 is a front view showing a tester attachment and a tester to which the tester attachment is attached according to embodiment 1. Tester attachment 1 includes attachment base 101, first attachment lead rod 102, second attachment lead rod 103, light-emitting unit 104, and a pair of release operation units 105.

[0011] The first attachment lead rod 102 and the second attachment lead rod 103 are each provided on the attachment base 101. The first attachment lead rod 102 and the second attachment lead rod 103 are arranged parallel to each other. The distance L1 between the first attachment lead rod 102 and the second attachment lead rod 103 is a preset value.

[0012] The distance between the first attachment lead rod 102 and the second attachment lead rod 103 is the distance between the center line of the first attachment lead rod 102 and the center line of the second attachment lead rod 103. The center line of the first attachment lead rod 102 is a center line that passes through the center of the first attachment lead rod 102 and extends in the longitudinal direction of the first attachment lead rod 102. The center line of the second attachment lead rod 103 is a center line that passes through the center of the second attachment lead rod 103 and extends in the longitudinal direction of the second attachment lead rod 103.

[0013] The light-emitting unit 104 is provided on the attachment base 101. A battery (not shown) is electrically connected to the light-emitting unit 104. When the battery is electrically connected to the light-emitting unit 104, power is supplied from the battery to the light-emitting unit 104. When power is supplied from the battery to the light-emitting unit 104, the light-emitting unit 104 emits light.

[0014] Each of the pair of release operating parts 105 is provided on the attachment base 101. The pair of release operating parts 105 is movable between a fixed position where a first lead rod 203 and a second lead rod 205, which will be described later, are fixed to the attachment base 101, and a released position where the first lead rod 203 and the second lead rod 205 are released from the attachment base 101. The pair of release operating parts 105 are arranged at the fixed positions by the elastic force of a spring (not shown). When an operator operates the pair of release operating parts 105 against the elastic force of the spring, the pair of release operating parts 105 moves from the fixed position to the released position.

[0015] The attachment base 101 is formed with a first insertion hole 106 and a second insertion hole 107 .

[0016] The tester attachment 1 is attached to a tester 2. The tester 2 includes a tester main body 201, a first wire harness 202, a first lead rod 203, a second wire harness 204, a second lead rod 205, a rotary switch 206, and a display unit 207.

[0017] One longitudinal end of the first wire harness 202 is connected to the tester body 201. The other longitudinal end of the first wire harness 202 is connected to a first lead rod 203.

[0018] One longitudinal end of the second wire harness 204 is connected to the tester body 201. The other longitudinal end of the second wire harness 204 is connected to a second lead rod 205.

[0019] The rotary switch 206 is provided on the tester main body 201. The rotary switch 206 is provided rotatably relative to the tester main body 201. By changing the rotational position of the rotary switch 206 relative to the tester main body 201, one measurement mode is selected from a plurality of measurement modes in the tester main body 201. Examples of measurement modes include a DC voltage measurement mode, an AC voltage measurement mode, a DC current measurement mode, and an AC current measurement mode.

[0020] The display unit 207 is provided on the tester main body 201. The display unit 207 displays a symbol indicating the selected measurement mode and characters indicating the measurement result.

[0021] The first lead rod 203 can be inserted into the first insertion hole 106. When the first lead rod 203 is inserted into the first insertion hole 106, the first attachment lead rod 102 and the first lead rod 203 are electrically connected to each other.

[0022] The second lead rod 205 can be inserted into the second insertion hole 107. When the second lead rod 205 is inserted into the second insertion hole 107, the second attachment lead rod 103 and the second lead rod 205 are electrically connected to each other.

[0023] The light emitting unit 104 and the battery are electrically connected by inserting the first lead pin 203 into the first insertion hole 106 and the second lead pin 205 into the second insertion hole 107. As a result, when the first lead pin 203 is inserted into the first insertion hole 106 and the second lead pin 205 is inserted into the second insertion hole 107, the light emitting unit 104 emits light.

[0024] In other words, when the first attachment lead rod 102 is electrically connected to the first lead rod 203 and the second attachment lead rod 103 is electrically connected to the second lead rod 205, the light emitting portion 104 emits light.

[0025] 2 is an enlarged view showing the first attachment lead rod 102 of FIG. 1. The first attachment lead rod 102 is formed in a cylindrical shape. The width dimension L2 of the first attachment lead rod 102 is a preset value. The tip of the first attachment lead rod 102 is hemispherical.

[0026] 3 is an enlarged view of the second attachment lead rod 103 of FIG. 1. The second attachment lead rod 103 is formed in a cylindrical shape. The width dimension L3 of the second attachment lead rod 103 is a preset value. The width dimension L3 of the second attachment lead rod 103 is the same as the width dimension L2 of the first attachment lead rod 102. The tip of the second attachment lead rod 103 is hemispherical.

[0027] FIG. 4 is an enlarged view showing the first lead rod 203 of FIG. 1. The first lead rod 203 is formed in a cylindrical shape. The width dimension L4 of the first lead rod 203 is a preset value. The width dimension L4 of the first lead rod 203 is the same as the width dimension of the first insertion hole 106. The width dimension L2 of the first attachment lead rod 102 is smaller than the width dimension L4 of the first lead rod 203. Therefore, the width dimension L2 of the first attachment lead rod 102 is smaller than the width dimension of the first insertion hole 106.

[0028] A first constricted portion 208 is formed on a portion of the first lead rod 203 on the tip side. One of the pair of release operation portions 105 has a fitting portion (not shown) that fits into the first constricted portion 208 of the first lead rod 203 when the first lead rod 203 is inserted into the first insertion hole 106. The fitting portion fitting into the first constricted portion 208 prevents the first lead rod 203 from being pulled out of the first insertion hole 106. When the pair of release operation portions 105 are in the fixed position, the fitting portion fits into the first constricted portion 208, and when the pair of release operation portions 105 are in the released position, the fitting portion comes off the first constricted portion 208.

[0029] FIG. 5 is an enlarged view showing the second lead rod 205 of FIG. 1. The second lead rod 205 is formed in a cylindrical shape. The width dimension L5 of the second lead rod 205 is a preset value. The width dimension L5 of the second lead rod 205 is the same as the width dimension of the second insertion hole 107. The width dimension L5 of the second lead rod 205 is also the same as the width dimension L4 of the first lead rod 203. The width dimension L3 of the second attachment lead rod 103 is smaller than the width dimension L5 of the second lead rod 205. Therefore, the width dimension L3 of the second attachment lead rod 103 is smaller than the width dimension of the second insertion hole 107.

[0030] A second constricted portion 209 is formed on a portion of the second lead rod 205 on the tip side. The other of the pair of release operation portions 105 has a fitting portion (not shown) that fits into the second constricted portion 209 of the second lead rod 205 when the second lead rod 205 is inserted into the second insertion hole 107. The fitting portion fitting into the second constricted portion 209 prevents the second lead rod 205 from being pulled out of the second insertion hole 107. When the pair of release operation portions 105 are in the fixed position, the fitting portion fits into the second constricted portion 209, and when the pair of release operation portions 105 are in the released position, the fitting portion comes off the second constricted portion 209.

[0031] When an operator operates the pair of release operating parts 105 against the elastic force of the springs, the pair of release operating parts 105 moves from the fixed position to the released position. When the pair of release operating parts 105 moves from the fixed position to the released position, the fitting part disengages from the first constricted portion 208 of the first lead rod 203, and the fitting part disengages from the second constricted portion 209 of the second lead rod 205. This makes it possible to pull out the first lead rod 203 from the first insertion hole 106, and the second lead rod 205 from the second insertion hole 107.

[0032] 6 is a perspective view showing a spring-type terminal block in an ID controller included in the access control device. The spring-type terminal block 3 has a plurality of electric wire insertion portions 301 into which a plurality of wires (not shown) are inserted one by one, and a plurality of tool insertion portions 302 into which tools (not shown) are inserted. The plurality of electric wire insertion portions 301 and the plurality of tool insertion portions 302 are arranged in a one-to-one correspondence. By inserting a tool into a tool insertion portion 302, the wire can be inserted into the corresponding electric wire insertion portion 301. With the wire inserted into the electric wire insertion portion 301, by removing the tool from the corresponding tool insertion portion 302, the wire is fixed to the electric wire insertion portion 301.

[0033] The plurality of electric wire insertion sections 301 include a pair of electric wire insertion sections for voltage measurement. The pair of electric wire insertion sections for voltage measurement is a pair of electric wire insertion sections 301 adjacent to each other and into which no wire is inserted. When maintenance and inspection of the ID controller is performed, the voltage between the pair of electric wire insertion sections for voltage measurement is measured.

[0034] The distance between the pair of voltage measurement electric wire insertion parts is the same as the distance L1 between the first attachment lead rod 102 and the second attachment lead rod 103. The distance between the pair of voltage measurement electric wire insertion parts is the distance between the centers of the pair of voltage measurement electric wire insertion parts.

[0035] The width of each of the pair of voltage measurement wire insertion portions is larger than the width L2 of the first attachment lead rod 102 and the width L3 of the second attachment lead rod 103. Therefore, the first attachment lead rod 102 and the second attachment lead rod 103 can be inserted into the pair of voltage measurement wire insertion portions.

[0036] Next, we will explain the procedure for measuring the voltage between a pair of voltage measurement wire insertion portions in an ID controller using tester attachment 1 and tester 2. Figure 7 is a side view showing how the voltage between a pair of voltage measurement wire insertion portions in an ID controller is measured using tester attachment 1 and tester 2.

[0037] First, the worker inserts the first lead rod 203 into the first insertion hole 106, and the second lead rod 205 into the second insertion hole 107. This attaches the first lead rod 203 and the second lead rod 205 to the attachment base 101. Furthermore, the first attachment lead rod 102 is electrically connected to the first lead rod 203, and the second attachment lead rod 103 is electrically connected to the second lead rod 205, causing the light emitting unit 104 to emit light.

[0038] The worker then holds tester attachment 1 in one hand and inserts first attachment lead rod 102 and second attachment lead rod 103 into each of the pair of voltage measurement electric wire insertion portions. If there are many wires around the pair of voltage measurement electric wire insertion portions, the worker holds tester attachment 1 in one hand and moves the wires around the pair of voltage measurement electric wire insertion portions with the other hand.

[0039] The voltage between the pair of voltage measurement wire insertion portions in the ID controller is measured by inserting first attachment lead rod 102 and second attachment lead rod 103 into each of the pair of voltage measurement wire insertion portions. The measured voltage value is displayed on display unit 207. The operator confirms the voltage between the pair of voltage measurement wire insertion portions in the ID controller by reading the characters displayed on display unit 207. This completes the procedure for measuring the voltage between the pair of voltage measurement wire insertion portions in the ID controller using tester attachment 1 and tester 2.

[0040] As described above, the tester attachment 1 according to the first embodiment includes the attachment base 101, the first attachment lead rod 102, and the second attachment lead rod 103. The attachment base 101 is formed with a first insertion hole 106 into which the first lead rod 203 of the tester 2 is inserted and a second insertion hole 107 into which the second lead rod 205 of the tester 2 is inserted. The first attachment lead rod 102 is provided in the attachment base 101. When the first lead rod 203 is inserted into the first insertion hole 106, the first attachment lead rod 102 is electrically connected to the first lead rod 203. The second attachment lead rod 103 is provided in the attachment base 101. When the second lead rod 205 is inserted into the second insertion hole 107, the second attachment lead rod 103 is electrically connected to the second lead rod 205. The first attachment lead rod 102 and the second attachment lead rod 103 are arranged parallel to each other. The distance L1 between the first attachment lead rod 102 and the second attachment lead rod 103 is a preset value. With this configuration, an operator can hold the tester attachment 1 in one hand and insert the first attachment lead rod 102 and the second attachment lead rod 103 into each of a pair of voltage measurement electric wire insertion portions. As a result, when there are many wires around the pair of voltage measurement electric wire insertion portions, the operator can hold the tester attachment 1 in one hand and move the wires around the pair of voltage measurement electric wire insertion portions with the other hand. As a result, the voltage between the pair of voltage measurement electric wire insertion portions in the ID controller can be easily measured.

[0041] Furthermore, in the tester attachment 1 according to the first embodiment, the width dimension L2 of the first attachment lead rod 102 is smaller than the width dimension of the first insertion hole 106, and the width dimension L3 of the second attachment lead rod 103 is smaller than the width dimension of the second insertion hole 107. With this configuration, the first attachment lead rod 102 and the second attachment lead rod 103 are easier to insert into the pair of voltage measurement electric wire insertion portions than the first lead rod 203 and the second lead rod 205. As a result, the voltage between the pair of voltage measurement electric wire insertion portions in the ID controller can be easily measured.

[0042] The tester attachment 1 according to the first embodiment also includes a light-emitting unit 104 provided on the attachment base 101. The light-emitting unit 104 emits light when the first attachment lead rod 102 is electrically connected to the first lead rod 203 and the second attachment lead rod 103 is electrically connected to the second lead rod 205. This configuration makes it easy for an operator to know that the first attachment lead rod 102 is electrically connected to the first lead rod 203 and the second attachment lead rod 103 is electrically connected to the second lead rod 205. Furthermore, the light emitted by the light-emitting unit 104 shines on the pair of voltage measurement electric wire insertion portions, making the pair of voltage measurement electric wire insertion portions more visible. This makes it easier to insert the first attachment lead rod 102 and the second attachment lead rod 103 into the pair of voltage measurement electric wire insertion portions.

[0043] Embodiment 2 Fig. 8 is a side view showing how the voltage of an ID controller is measured using tester attachment 1 and tester 2 according to embodiment 2. Fig. 9 is a side view, seen from the rear side, showing how the voltage of an ID controller is measured using tester attachment 1 and tester 2 of Fig. 8.

[0044] The first attachment lead rod 102 has a first attachment lead rod base end 108 and a first attachment lead rod tip end 109. The first attachment lead rod base end 108 is provided on the attachment base 101. The first attachment lead rod tip end 109 is provided on the first attachment lead rod base end 108.

[0045] When viewed along the direction in which the first attachment lead rod 102 and the second attachment lead rod 103 are aligned, the first attachment lead rod tip 109 is arranged at an angle relative to the direction along the first attachment lead rod base end 108.

[0046] The second attachment lead rod 103 has a second attachment lead rod base end 110 and a second attachment lead rod tip end 111. The second attachment lead rod base end 110 is provided on the attachment base 101. The second attachment lead rod tip end 111 is provided on the second attachment lead rod base end 110.

[0047] When viewed along the direction in which the first attachment lead rod 102 and the second attachment lead rod 103 are aligned, the tip end 111 of the second attachment lead rod is arranged at an angle relative to the direction along the base end 110 of the second attachment lead rod.

[0048] First attachment lead rod tip end 109 and second attachment lead rod tip end 111 are inserted into a pair of voltage measurement electric wire insertion portions. First attachment lead rod base end 108 and second attachment lead rod base end 110 are arranged around the pair of voltage measurement electric wire insertion portions and away from area A on an extension of the voltage measurement insertion portions. As a result, tester attachment 1 and tester 2 are arranged away from area A.

[0049] Other configurations of the tester attachment 1 according to the second embodiment are the same as those of the tester attachment 1 according to the first embodiment.

[0050] As described above, in the tester attachment 1 according to embodiment 2, the first attachment lead rod 102 has a first attachment lead rod base end 108 and a first attachment lead rod tip end 109. The first attachment lead rod base end 108 is provided on the attachment base 101. The first attachment lead rod tip end 109 is provided on the first attachment lead rod base end 108. The second attachment lead rod 103 has a second attachment lead rod base end 110 and a second attachment lead rod tip end 111. The second attachment lead rod base end 110 is provided on the attachment base 101. The second attachment lead rod tip end 111 is provided on the second attachment lead rod base end 110. When viewed along the direction in which the first attachment lead rod 102 and the second attachment lead rod 103 are arranged, the first attachment lead rod tip 109 is arranged at an angle relative to the direction along the first attachment lead rod base end 108. When viewed along the direction in which the first attachment lead rod 102 and the second attachment lead rod 103 are arranged, the second attachment lead rod tip 111 is arranged at an angle relative to the direction along the second attachment lead rod base end 110. With this configuration, when there are many wires in area A around the pair of voltage measurement wire insertion portions and on the extension line of the voltage measurement insertion portions, the tester attachment 1 and the tester 2 can be arranged so as to be separated from the wires. As a result, the voltage between the pair of voltage measurement wire insertion portions in the ID controller can be easily measured.

[0051] In the tester attachment 1 according to each embodiment, both the first attachment lead rod 102 and the second attachment lead rod 103 are fixed to the attachment base 101. However, at least one of the first attachment lead rod 102 and the second attachment lead rod 103 may be configured to be slidable relative to the attachment base 101 so that the distance between the first attachment lead rod 102 and the second attachment lead rod 103 is adjustable. This allows the tester attachment 1 to be used for multiple types of ID controllers that have different dimensions between a pair of voltage measurement wire insertion portions.

[0052] Furthermore, in the tester attachment 1 according to each embodiment, a configuration has been described in which an operator checks the voltage between a pair of voltage measurement wire insertion portions in the ID controller by reading characters displayed on the display unit 207. However, the tester attachment 1 may be configured to include an alarm device that, when the voltage value between the pair of voltage measurement wire insertion portions is within a preset range, notifies the operator that the voltage value between the pair of voltage measurement wire insertion portions is within the preset range. An example of the alarm device is a speaker device.
