In this embodiment, the second elastic member 10 can be a spring, and the stop block 09 is provided with a plurality of circular holes ( Figure 2 and Figure 3 In the embodiment shown, the limit block 09 is provided with two circular holes, which are respectively used to fit the second elastic member (spring in this embodiment) 10, the hole wall guides the second elastic member 10 and the hole walls of the two circular holes are provided with small protrusions, which are used to limit the second elastic member 10 and prevent it from falling out; the limit block 09 is fixedly installed on the back of the second bonding sheet 08, the second elastic member 10 is located between the second bonding sheet 08 and the shell wall of the housing 00, and there is a gap between the limit block 09 and the shell wall of the housing 00. Preferably, in this embodiment, an arc-shaped protrusion 051 is provided on one side of the vertical wall of the first bonding sheet 05 that is bonded to the second bonding sheet 08, and the arc-shaped protrusion 051 is located in the wiring port 010, which helps to directly insert the wiring terminal of the sensor element when the wiring port 010 is not opened.
[0113] The first bonding sheet 05 and the conductive column 04 of the crimping terminal 100 are both made of a tellurium copper alloy with a metal coating. The tellurium copper alloy has excellent electrical and thermal conductivity. After gold plating, it plays a role in corrosion resistance and wear resistance, and can further reduce the contact potential. The first bonding sheet 05 can be a block of metal, which has a heat pool effect and has a rapid heat equalization effect on the friction heat generated when the terminal is connected.
[0114] Reference Figures 1 to 3 The crimping terminal 100 also includes a color code 07, which is installed at the upper opening of the push button 03. The color code 07 has different colors. For example, the red color code identifies the positive pole, the black color code identifies the negative pole, and the green color code identifies the ground wire.
[0115] When the crimping terminal 100 is working, if the connection terminal of the sensor element with a banana plug 001 is plugged in, the banana plug 001 is directly inserted into the receiving cavity of the push button 03 through the color code 07 and is in close contact with the conductive column (this embodiment refers to the banana socket) 04; if the connection terminal of the sensor element with a bare wire 002 or a spade plug 003 is plugged in, such as Figure 4 As shown, by pressing the button 03, the first elastic member 06 is compressed, causing the button slope 031 to move downward, thereby squeezing the first slope 081 or the first arc surface in contact therewith, so that the second elastic member 10 is compressed, and the second bonding sheet 08 moves horizontally to the right ( Figure 4 The right side of the housing 00 is moved so that the wiring port 010 between the vertical wall of the first bonding sheet 05 and the second bonding sheet 08 is opened (enlarged). At this time, the bare wire 002 or the spade plug 003 is inserted into the wiring port 010 through the second opening of the housing 00; Figure 5 As shown, the button 03 is released, and the second bonding sheet 08 moves to the left ( Figure 5 The first elastic member 06 moves the pressing button 03 upwards, so that the bare wire 002 or the spade plug 003 is firmly clamped in the connection port 010 formed by the vertical wall of the first bonding sheet 05 and the second bonding sheet 08 (at this time, the bare wire 002 or the spade plug 003 is subjected to a double elastic force). Compared with the traditional screwing method, the crimping method of the crimping terminal 100 can reduce friction and reduce the heat generated by friction, thereby achieving the effect of reducing the contact potential between the terminal of the sensor element and the crimping terminal.
[0116] Embodiment 2
[0117] like Figure 6 As shown, the crimping terminal 101 of the second embodiment is a modification based on the crimping terminal 100 of the first embodiment, and the parts with the same structure as the crimping terminal 100 of the first embodiment will not be repeated here. The difference between the crimping terminal 101 of this embodiment and the crimping terminal 100 of the first embodiment is that the two pressing button inclined surfaces 031 of the push button 03 are replaced by two pressing button arc surfaces 032, and the pressing button arc surfaces 032 are vertically arranged, and the contact area with the second inclined surface 081 is relatively small (line contact). At this time, in order to prevent the second bonding sheet 08 from deforming, the second bonding sheet 08 can be thickened. Of course, the pressing button inclined surface 031 of the push button 03 can also be replaced by end surfaces of other shapes, as long as the end surface of the push button 03 can be in contact with the first inclined surface 081, and the vertical movement of the push button 03 can be converted into the horizontal movement of the second bonding sheet 08.
[0118] Embodiment 3
[0119] like Figure 7As shown, the crimping terminal 102 of the third embodiment is an improvement on the crimping terminal 100 of the first or second embodiment, and the parts with the same structure as the crimping terminal 100 of the first or second embodiment are not repeated here. The crimping terminal 102 of this embodiment is different from the crimping terminal 100 of the first embodiment or the crimping terminal 101 of the second embodiment in that the elastic mechanism is a C-shaped spring sheet 18, and the C-shaped spring sheet 18 is located between the second bonding sheet 08 and the inner wall of the housing 00 ( Figure 7 At least one end of the C-shaped opening of the C-shaped spring sheet 18 is supported on the second bonding sheet 08 and the C-shaped closed end surface is in contact with the inner wall of the shell 00.
[0120] When the crimping terminal 102 is working, if the terminal of the sensor element with the bare wire 002 or the spade plug 003 is plugged in, the pressing button 03 is pressed, and the first elastic member 06 is compressed, so that the pressing button inclined surface 031 or the pressing button arc surface 032 moves downward, thereby squeezing the first inclined surface 081 or the first arc surface in contact therewith, so that the C-shaped spring piece 18 is extended and the curvature becomes smaller, and the second bonding piece 08 moves horizontally under the action of the pressing button inclined surface 031, so that the connection port 010 between the vertical wall of the first bonding piece 05 and the second bonding piece 08 is opened, and at this time, the bare wire is inserted into the first bonding piece 05. 002 or spade-shaped plug 003 is inserted into the wiring port 010 through the second opening on the housing 00; the pressing button 03 is released, the arc of the C-shaped spring sheet 18 becomes larger (restoring the original arc), and the second bonding sheet 08 moves horizontally in the opposite direction under the elastic force of the C-shaped spring sheet 18, and the pressing button 03 moves upward under the action of the first elastic member 06, so that the bare wire 002 or spade-shaped plug 003 is firmly clamped in the wiring port 010 between the vertical wall of the first bonding sheet 05 and the second bonding sheet 08 (at this time, the bare wire 002 or spade-shaped plug 003 is subjected to double elastic force). Compared with the traditional screwing method, the crimping method of the crimping terminal 102 can also reduce friction and reduce the heat generated by friction, thereby achieving the effect of reducing the contact potential between the plug and the terminal.
[0121] Embodiment 4
[0122] Reference Figures 8 to 11 , is a structural diagram of a crimping terminal 103 of the fourth embodiment. The crimping terminal 103 of this embodiment is different from the above-mentioned crimping terminals in that the structure of the second bonding sheet 08 is different, such as Fig. 9As shown, the second bonding sheet is an S-shaped crimping block 17, which is arranged between the push button 03 and the vertical wall of the first bonding sheet 05. The lower part of the push button 03 is rotatably connected to the S-shaped lower folded end of the crimping block 17, and the crimping block 17 can rotate along the rotating shaft 172 provided at the lower folded end. The crimping block 17 is provided with a vertical crimping plate, and the rotating shaft 172 is provided at the bottom of the crimping plate. The upper folded end 171 of the crimping block 17 serves as a pressure edge and contacts the vertical wall of the first bonding sheet 05 to form a wiring port 010; the lower folded end of the crimping block 17 is provided with a pressure column 173, and the pressure column 173 is installed in the pressure button limiting hole 033 provided at the lower part of the push button 03, and the pressure column 173 is movable in the pressure button limiting hole 033. In this embodiment, the rotating shaft 172 is installed in the mounting hole 022 provided on the side wall of the housing 00, and the crimping block 17 can rotate along its rotating shaft 172.
[0123] When the crimping terminal 103 is working, if it is plugged into the terminal of the sensor element with a bare wire 002 or a spade plug 003, Fig.10 As shown, by pressing the push button 03, the first elastic member 06 is compressed, causing the push button 03 to move downward, thereby driving the pressure column 173 of the crimping block 17 to move downward (the push button limit hole 033 is an elliptical hole with a moving space, and the pressure column 173 can move in the push button limit hole 033 to meet the purpose of the crimping block 17 being able to rotate along the rotation axis 172), so that the crimping block 17 rotates along the rotation axis 172, so that the connection port 010 between the upper folded end (pressure edge) 171 and the vertical wall of the first bonding sheet 05 is opened. At this time , insert the bare wire 002 or the spade plug 003 into the wiring port 010 through the second opening 013 of the housing 00; release the push button 03, the push button 03 moves upward under the action of the first elastic member 06, driving the pressure column 173 to move upward (while the pressure column 173 moves in the push button limit hole 033), the crimping block 17 rotates around the rotating shaft 172, so that the bare wire 002 or the spade plug 003 is firmly clamped in the wiring port 010 between the vertical wall of the first bonding sheet 05 and the upper folded end 171 of the crimping block 17. Compared with the traditional screwing method, the crimping method of the crimping terminal 103 can also reduce friction and reduce the heat generated by friction, thereby achieving the effect of reducing the contact potential between the plug and the terminal.
[0124] Figures 12 to 17 The structure of the crimping terminal module 200 includes at least two crimping terminals. The crimping terminals in the crimping terminal module 200 can be one or a combination of two of the crimping terminals 100, 101, 102, and 103 mentioned above. The shells of the terminal blocks are integrated into a shell of the crimping terminal module.
[0125] Fig.13In the embodiment described, each crimping terminal further includes a temperature sensor, which senses the temperature of the first bonding sheet 05, and further senses the temperature of the sensing element inserted into the wiring jack 034 or the wiring port 010, for compensating the detected temperature difference potential. In order to facilitate the installation and wiring of the temperature sensor, each crimping terminal further includes a compensation plate 14 and a compensation plate support 15, on which a metal guide is provided, and the compensation plate 14 is an insulator with good thermal conductivity, and the metal guide is in contact with the first bonding sheet 05, and the temperature sensor senses the temperature of the first bonding sheet 05 by sensing the temperature of the metal guide. In one embodiment, the sensor is not connected to the metal guide near the metal sheet, and the sensor detects the air temperature near the metal sheet, thereby sensing the temperature of the first bonding sheet 05. A third opening 021 is provided at the bottom of the housing 00 at a position corresponding to the first bonding sheet 05. The compensation plate 14 is mounted on the outer side of the bottom of the housing 00 and the metal guide thereon contacts the first bonding sheet 05 through the third opening 021. The compensation plate support 15 is buckled with the compensation plate 14. The terminal electrically connected to the temperature sensor can extend from the through hole provided in the compensation plate support 15 so as to be connected to the circuit board 11. The metal guide and the temperature sensor are respectively arranged on the upper and lower sides of the compensation plate 14.
[0126] Reference Figures 12 to 17 The crimping terminal module 200 in this embodiment is composed of four crimping terminals. Terminal 1, terminal 2, terminal 3 and terminal 4 are formed by extending the upper part of the pressing button 03 of the four crimping terminals out of the first opening provided on the shell. The second openings provided on the shell are arranged on both sides. The second openings are respectively aligned with the wiring ports 010 of each crimping terminal. The two second openings on each side can be used to plug in the wiring terminals of the sensor element with a Min-TC plug (see Fig.17 ). In this embodiment, the first bonding sheet 05 of each crimping terminal is in contact with the metal guide sheet arranged on the compensation plate 14. In one embodiment, the metal sheets are close to each other and the metal sheets are close to the sensor but not connected. The sensor measures the air temperature near the metal sheet, thereby sensing the temperature of the metal sheet.
[0127] like Fig.17 As shown, two buckles 011 are provided on the shell of the crimping terminal module 200, and a panel 13 can be directly connected to the shell through the buckles 13. The advantage of such a setting is that the panel 13 can be easily installed and disassembled without falling off.
[0128] The crimping terminal module 200 can be used to connect a set of four-wire or three-wire thermocouples, or can be used to connect two sets of two-wire thermocouples or thermal resistors, for example. Fig.15 and Fig.17As shown, multifunctional terminal 1, terminal 2, terminal 3, and terminal 4 can be combined in pairs to connect two-wire thermocouples or thermal resistors. Which two combinations can achieve the predetermined detection function depends on the circuit setting of the circuit board 11 and the connection between each terminal and the circuit board 11. The specific circuit setting of the circuit board 11 can be implemented using an existing detection circuit board, which is not the focus of this application and will not be discussed here.
[0129] The above embodiment is only an example of a crimping terminal module formed by combining the crimping terminals 100. Similarly, any one or more combinations of crimping terminals 100, 101, 102, 103 can also be combined into a crimping terminal module with the same function. The structure is basically the same and will not be repeated here.

[0132] Fig.19 In the illustrated embodiment, the channel bin 400 includes a plurality of crimping terminal modules 200, the panel 13 is placed above the circuit board 11 and fixed, and after the plurality of crimping terminal modules 200 are mounted on the panel 13, they are respectively connected to the circuit board 11, and the circuit board 11 is connected with a plurality of common terminals 300 for grounding, and the circuit board 11 is provided with at least one line interface electrically connected to the host 600 and one line interface serially connected to the channel bin 400. The crimping terminal modules 200 may be terminals of different specifications and uses.
[0133] Based on the limited resources of the circuit board 11, the working mode of the crimping terminal module 200 of the channel warehouse 200 in this embodiment is the inspection mode, that is, the signal output circuit of each crimping terminal module is connected to the relay switch set on the circuit board 11, and the on and off of the output circuit corresponding to the crimping terminal module 200 is controlled by the relay switch, so that the crimping terminal module 200 occupies the resources of the circuit board 11 according to a certain logical control order.
[0134] The circuit board 11 is provided with a straight socket 111 and a wiring port 1 112 for data interaction with the host 600, a wiring port 2 113 for serially connecting the channel bin 400, a power socket 114 for connecting a power source, and an indicator light socket 115 for connecting the indicator light FPC circuit board 25. The straight socket 111, the wiring port 1 112, and the wiring port 2 113 are arranged on two opposite sides of the circuit board 11. The indicator light FPC circuit board 25 is installed on the inner lining of the panel 13 and is connected to the circuit board 11 through the indicator light socket 115. A plurality of indicator lights 26 are provided on the indicator light FPC circuit board 25. The indicator light 26 extends to the outside of the panel 13 and is used to indicate the working status of each crimping terminal module 200.
[0135] like Fig.18 As shown, a plurality of crimping terminal modules 200 mounted on the panel 13 are integrally placed with the circuit board 11 in the lower shell 20 with an upper opening, and the straight socket 111 extends out of the shell wall of the lower shell 20, and the wiring port 1 112 and the wiring port 2 113 are located on the opposite side of the straight socket 111, and through holes are provided at corresponding positions thereof so that the wiring port 1 112 and the wiring port 2 113 can be externally connected to corresponding wire terminals, and a socket cover 21 is also provided at the through hole position, and the socket cover 21 is mounted on the shell wall of the lower shell 20, and can be flipped open and fastened closed relative to each other. When not in use, the wiring port 1 112 and the wiring port 2 113 can be sealed and protected by closing the socket cover 21. The power socket 114 can be set on the same side of the digital wiring port 1 112 and the wiring port 2 113, and exposed on the outer surface of the lower shell 20, so as to facilitate the connection of the power supply. When the channel bin 400 is used alone, the circuit board 11 in the channel bin 400 can be powered by the power socket 114. When the channel bin 400 is connected to the host 600, the power supply can be disconnected.
[0136] like Fig.18 As shown, the channel bin 400 is also provided with a channel bin cover 22, which covers the opening of the lower shell 20, and a wire outlet 23 is provided between the channel bin cover 22 and the lower shell 20. The crimping terminal module 200 on the channel bin is wired, and when the channel bin cover is closed, the crimping terminal module 200 wires can pass through the wire outlet 23. The crimping terminal module 200 can have a windproof protection function, and the temperature of the crimping terminal connection contact position can be further stabilized, which helps to improve the temperature calibration accuracy.
[0137] The channel compartment 400 and the host 600 cooperate to form the temperature calibration instrument 500 of the present invention, see Fig. 20The host 600 is used to interact with the channel bin 400, that is, to receive the temperature detection data and electrical parameters of the channel bin 400, and to send a control command to the circuit board 11 of the channel bin 400 to control the on and off of the relay switch on the circuit board 11, thereby realizing the inspection of the crimping terminal module 200; the host 600 is also provided with a display screen, and the host obtains the result data according to the electrical parameters, and displays the obtained result data on the display screen.
[0138] like Fig. 20 As shown, the upper part of the host 600 is provided with a receiving groove for receiving the opening on one side of the channel bin 400, the middle groove wall of the receiving groove is provided with a host socket 52 matching the straight socket 111 of the channel bin 400, the groove walls on both sides of the receiving groove are symmetrically provided with guide rails 50, the bottom of the receiving groove is provided with a card groove 51, and the edge of the opening side of the receiving groove is provided with a buckle groove 53, and the space of the buckle groove 53 is preferably enough to accommodate a finger. The host 600 is also provided with a connection line interface 54 for connecting the wiring port 112 of the channel bin 400.
[0139] See also Fig.21 In order to realize the detachable integrated assembly of the channel bin 400 and the host 600, a button 27 and a buckle 28 are provided at the bottom of the lower shell 20 of the channel bin 400 on the side where the wiring port 1 112 and the wiring port 2 113 are located. The buckle 28 is fixedly connected to the button 27. A through hole is provided at the bottom of the lower shell 20 at the position corresponding to the buckle 28 and the button 27. The buckle 28 and the button 27 can extend out of the shell of the lower shell 20 through the corresponding through hole. Pressing the button 27 can drive the buckle 28 to move upward. When the button 27 is released, the buckle 28 moves downward and extends out of the lower shell 20. The lower shell 20 of the channel bin 400 is symmetrically provided with slide grooves 131 on both sides of the shell, and the slide grooves 131 match the guide rails 50 on the host. When the channel bin 400 and the host 600 are installed, the side where the straight socket 111 of the channel bin 400 is located is pushed in from the opening side of the accommodating slot of the host 600, and the buckle 28 of the channel bin 400 is aligned with the center position of the slot 51 of the host 600, and the size of the buckle 28 is smaller than the size of the slot 51. During the advancement of the channel bin 400, the buckle 28 is squeezed by the front edge of the slot 51 and bounces upward, and the guide rail 50 of the host 600 enters the slide groove 131 of the channel bin 400 until the straight socket 111 of the channel bin 400 is fully plugged into the host socket 52 of the host 600. At this time, the buckle 28 passes over the front edge of the slot 51 and releases and rebounds, thereby falling into the slot 51, and the channel bin 400 and the host are locked and fixed. When removing the channel bin 400, insert your finger into the buckle groove 53 of the host, press the button 27 upward, so that the buckle 28 pops up, and while holding down the button 27, drag the channel bin 400 outward to separate the channel bin 400 from the host 600.
[0140] The above components are assembled into the channel bin 400 and the temperature calibrator 500 of the present invention according to the above-mentioned connection relationship. The crimping terminal module 200 of the channel bin 400 can be connected to the wiring terminals of the sensor element by means of a button. Compared with the traditional screwing method, it can reduce the heat generated by friction and reduce the contact potential of the wiring terminals of the sensor element; a compensation plate is arranged in the crimping terminal module 200, which helps to compensate for the temperature difference potential and improve the detection accuracy; the crimping terminal modules of the channel bin 400 of the present invention work in a patrol mode, which is easy to realize automated operation and helps to improve the work efficiency of batch detection; the channel bin 400 can be used alone, and can also be detachably installed with the host 600, which is flexible to use.
[0141] There are three main ways to connect the channel compartment 400 and the host 600:
[0142] Fig. 22 In the connection mode 1 shown, the wiring port 1 112 of the channel bin 400 is connected to the host socket 54 of the host 600 through a connecting line 55, and the wiring port 2 113 of the channel bin 400 is electrically connected to the wiring port 1 112 of another channel bin 400 through the connecting line 55. In the same way, multiple channel bins 400 can be connected in series in sequence. Considering the limited configuration resources of the host 600 and the accuracy requirements of the detection, the number of channel bins 400 connected in series by the host 600 is generally not more than three. When working, the channel bins 400 connected in series by the host 600 also work in a patrol mode. The host 600 transmits the control command to the channel bin directly connected thereto, and then transmits it to the next channel bin through the wiring port 2 113 of the channel bin, and then transmits it to the last channel bin in sequence. The control logic set by the host controls the relay switch on the circuit board 11 of each channel bin to control the working state of each crimping terminal module 200.
[0143] This working mode is particularly suitable for batch testing of temperature sensing elements of different ranges or accuracies placed in different temperature control devices, which not only improves the testing efficiency but also reduces the testing cost.
[0144] Fig.23 In the second connection method shown, the channel bin 400 is installed in the receiving slot of the host 600 and forms a whole with the host 600. The straight socket 111 of the channel bin 400 is plugged into the host socket 52 of the host 600. The channel bin 400 also works in a patrol working mode.
[0145] Fig.24In the third connection mode shown, the channel bins 400 are installed in the receiving slots of the host 600, and after being formed into a whole with the host 600, they can also be connected to the connection line interface 54 of the host 600 through the connection port 112 of the channel bin 400, and multiple channel bins 400 can be connected in series. In this working mode, all the channel bins 400 work as a whole and also adopt the inspection mode.
