[0023] Preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to make the present disclosure more thorough and complete, and to fully convey the scope of the present disclosure to those skilled in the art.

The term "based on" means "at least partially based on". The terms "an example embodiment" and "an embodiment" mean "at least one example embodiment".

[0025] As mentioned above, during the production process of electronic detonators, it is necessary to detect multiple electrical performance parameters of the control module of the electronic detonator. For example, communication, timing, and detonation working parameters, etc. Currently, commonly used detection devices usually include several channels to improve the detection efficiency. Each channel is used to detect the electrical performance parameters of a control module, and then the results of the electrical performance detection are displayed on the display screen of the module electrical performance detection device itself or the upper computer screen of the manufacturer. The more the number of detection channels, the larger the occupied area of the circuit board plane of the detection device, resulting in a relatively large size of the detection device, and it will occupy too much area when applied to the workstations in the production factory. In addition, if there is a problem with one of the channel circuits of the detection device, the entire circuit board of the detection device needs to be replaced, and the replacement operation is complex, time-consuming, and costly.
[0026] In view of this, according to an embodiment of the present disclosure, a detection device facilitating the replacement of detection channels is provided. By respectively arranging the circuit of each detection channel on a channel circuit board detachably and vertically installed on the control main board, the detection channels of the detection device are convenient to replace and more space-saving. The principle of the control module for the coil of the switch device according to the embodiment of the present disclosure will be described in detail below with reference to the accompanying drawings.
[0027] Figure 1 and Figure 2 respectively show the three-dimensional structure and top view of the detection device facilitating the replacement of detection channels according to an embodiment of the present disclosure. As Figure 1-2As shown, the detection device 1 may include a control main board 10 and multiple channel circuit boards 20 for collecting detection electrical parameters and sending them to the control main board 10. Usually, a channel circuit corresponding to the design of an electronic detonator control module is provided on one channel circuit board 20, which is used to collect or detect the electrical performance parameters of the control module and send them to the control main board 10. Therefore, an inspection device of the present disclosure can detect multiple electronic detonator control modules simultaneously. In one or more embodiments of the present disclosure, the channel circuit may include a detection control chip, a buck-boost module, a PWM control module, an input-output module, etc. to implement the collection and transmission of electrical performance parameters. The control main board 10 generally includes a main control chip, a power supply (not shown in the drawings to highlight the design points of the present disclosure), and a bus interface 120. On the one hand, the main control chip is electrically connected to the power supply to obtain working power, and on the other hand, it can communicate with the host computer through the bus interface 120 and send the detection results to the host computer for display. In order to facilitate the replacement of the detection channels of the detection device and save more space, in the embodiments of the present disclosure, the control main board 10 is provided with a first connector 110, and the channel circuit board 20 is provided with a second connector 210 adapted to the first connector 110, so that the channel circuit board 20 can be detachably mounted on the control main board 10 through the second connector 210 to achieve data transmission between the two.
[0028] As Figure 3 shown, in one or more embodiments of the present disclosure, the first connector 110 may include several conductive interfaces 1120, which have contactable conductive parts for electrically connecting the second connector 210; correspondingly, the second connector 210 may include several conductive sheets 211 provided corresponding to the respective conductive interfaces 1120. When the second connector 210 is adaptively connected to the first connector 110, the conductive sheets 211 of the second connector 210 are exactly inserted into the corresponding conductive interfaces 1120 and contact the conductive parts of the conductive interfaces, realizing the installation of the channel circuit board 20 on the control main board 10. Specifically, in one or more embodiments of the present disclosure, the first connector 110 may include a mounting base having several connection sockets arranged in a row, and a pair of pins 1110 are provided in each connection socket. The two pins are relatively and spaced apart in the connection socket, and the connection socket has an opening at the interval corresponding to the two pins to expose the interval, forming the conductive interface 1120. Correspondingly, the second connector 210 may include a connection plate protruding from one side edge of the channel circuit board 20. For example, the entire channel circuit board 20 may be a "convex"-shaped panel structure, and the connection plate corresponds to the protruding part of the "convex" character. As Figure 4As shown, the conductive sheet 211 can be provided on the surface of the connection board, facilitating the overall insertion of the connection board into the mounting seat of the first connector 110, such that the conductive sheet 211 is also correspondingly located in the corresponding conductive interface 1120 as the connection board is inserted as a whole. Specifically, the conductive sheet 211 can be arranged only on one side surface of the connection board, or can be arranged on both side surfaces of the connection board. Those skilled in the art can select a suitable arrangement method according to the actual situation and practical needs. In the case where the conductive sheet 211 is arranged only on one side surface of the connection board, in one embodiment of the present disclosure, conductive structures 1111 can be provided at the ends of the pins 1110 on the same side of the entire row of sockets of the mounting seat, serving as the conductive parts of the conductive interface 1120 to achieve electrical connection with the conductive sheet 211. In another embodiment of the present disclosure, conductive structures can also be provided at the ends of the two pins 1110 of the entire row of sockets of the mounting seat, such that the insertion direction of the connection board is not restricted.
[0029] Through the above embodiments, the present disclosure redesigned the structure of the detection device, such that each detection channel of the detection device corresponds to a separately detachable channel circuit board 20, facilitating the replacement of the detection channels. At the same time, each channel circuit board is vertically mounted on the control main board 10, such that the channel circuits are arranged on a vertical plane that is substantially perpendicular to the control main board, saving more space.
[0030] In one or more embodiments of the present disclosure, the conductive structure 1111 can be a curved conductive elastic sheet, which has a curved portion and thus has a certain deformation ability. As Figure 5 shown, the curved conductive elastic sheet can be a "U"-shaped conductive sheet, whose closed end is used to connect the pin 1110, and the open end is arranged facing the other pin in a pair of pins. When the connection board is inserted into the mounting seat of the first connector 110, the two conductive points at the open end of the "U"-shaped conductive sheet can contact the conductive sheet on the first connection board, realizing the electrical connection between the control main board 10 and the channel circuit board 20. When connection boards of different thicknesses are inserted during installation, it will cause different degrees of deformation of the "U"-shaped conductive sheet (i.e., different "U" openings), which can ensure the contact area while saving the material used for the conductive structure.
[0031] In one or more embodiments of the present disclosure, in order to simplify the production process, the entire pin 1110 is usually designed to be made of a conductive material. When the connection board is inserted into the mounting seat of the first connector 110, since the thickness of the connection board will cause extrusion of the pin 1110 in the mounting seat, in order to prevent the pin 1110 from being overly deformed and broken after being extruded, in one or more embodiments of the present disclosure, the pin 1110 is rotatably arranged on the control main board 10. For example, a rubber ring with a suitable friction coefficient can be selected and installed in the mounting hole on the control main board, or it can be connected to the control main board through a rotating shaft.
[0032] In order to avoid short circuits caused by contact between pins, in some other embodiments of the present disclosure, an insulating member 1130 may also be provided between each pair of pins, so as to space apart two adjacent conductive interfaces 1120. The insulating member 1130 may be a plastic baffle. On the one hand, it can avoid short circuits caused by pin contact. On the other hand, it can also limit the pins 1110 to prevent excessive displacement and inability to contact the conductive sheet.
[0033] The detection device 1 can also communicate with the host computer through the bus interface 120 to implement a detection system that facilitates the replacement of detection channels. Among them, the host computer has functions such as data display, storage, and uploading to the cloud server, and can provide a unified display interface for the data obtained after batch detection and control of the detection device modules, which is convenient for viewing.

Certain features described in the context of separate embodiments can also be implemented in combination in a single implementation. Conversely, the various features described in the context of a single implementation can also be implemented separately or in any suitable sub-combination in multiple implementations.
