Description

Technical Field

[0002] Large-scale automated production lines, industrial automation equipment, robots and other industries all involve a large number of signal transmission terminals. Various signal connection terminals, as nodes for signal transmission, play a very important role. For example, in the intelligent manufacturing industry, with the improvement of the intelligence level of industrial automation equipment, its functions are more abundant, and the number of signal transmission nodes is increasing.

[0003] At present, when industrial automation equipment selects signal connectors, standard parts are generally chosen for cost and subsequent maintenance considerations. However, the number of general standard connector probes is limited. In the case of large fixture facilities that require more signal induction transmission, in order to meet the signal transmission needs, the number of signal transmission connectors is often increased. Equipped with multiple signal transmission connectors, the wiring in the equipment is more complicated, which increases the difficulty of subsequent maintenance. If more probes are added to a single signal connector, it will be more difficult to align the signal channel when the connector is connected. Whether it can maintain a reliable connection state for a long time after connection is also a problem that needs to be considered.

[0004] Therefore, it is necessary to design a more reliable integrated multi-pin signal transmission connection structure to meet more signal transmission requirements of industrial automation equipment, such as large fixture facilities. Utility Model Content

[0030] See also Figure 1~Figure 4 . Figure 1 A schematic diagram of the structure of an integrated multi-pin signal transmission connector in an unconnected state provided by an embodiment of the utility model; Figure 2 A schematic diagram of a connection state of an integrated multi-pin signal transmission connector structure provided by an embodiment of the utility model; Figure 3 A schematic diagram of the internal structure of a flat pin and an elastic pin provided in an embodiment of the utility model; Figure 4 A schematic diagram of connector wiring provided in an embodiment of the utility model.

[0031] Combination Figure 1 and Figure 2As shown, an integrated multi-pin signal transmission connector provided in this embodiment includes a first connection module 1 and a second connection module 2, wherein the first connection module is provided with at least two first positioning columns 102 and a plurality of elastic pins 101, and the second connection module 2 is provided with at least two second positioning columns 202 and a plurality of flat pins 201. All the first positioning columns 102 and all the second positioning columns 202 are arranged in pairs, and each first positioning column 102 and its corresponding second positioning column 202 form a positioning column group, and at least one positioning column group is provided with a magnetic anti-detachment mechanism 3 to prevent the paired first positioning column 102 and its corresponding second positioning column 202 from being separated. By cooperating with each other through at least two positioning column groups, precise docking and positioning between the elastic pins 101 and the flat pins 201 can be achieved. When the first positioning column 102 and the second positioning column 202 are positioned and matched, the plurality of the elastic pins 101 and the plurality of the flat pins 201 are abutted and matched one by one to achieve signal transmission.

[0032] It is understandable that in order to meet the multi-channel signal transmission requirements of large-scale automated industrial equipment (this embodiment uses a large fixture as an example) and standardize the wiring in the equipment, this embodiment provides a signal transmission connector that integrates more signal transmission pins and is suitable for more signal transmission channels. Figure 1 For example, 30 elastic pins 101 are arranged on the first connection module, and correspondingly, 30 flat pins 201 are arranged on the second connection module 2. The signal transmission of the connector can be realized through the electrical connection between the elastic pins 101 and the flat pins 201. Specifically, when the elastic pins 101 and the flat pins 201 are in contact with each other, the signal sensing instruction on the fixture is transmitted through the contact between the flat pins 201 and the elastic pins 101, and the signal is input to the fixture control system. When the control system receives the electrical signal, it issues the next step instruction to complete other process operations.

[0033] Since the number of integrated probes (flat pins 201 and elastic pins 101) in this embodiment is relatively large, the number of connectors inside the device can be reduced, making the wiring of the signal line 5 inside the device more standardized and neat, which is conducive to subsequent device maintenance. However, due to the large number of probes, when the first connection module 1 and the second connection module 2 of the connector are docked, it is also difficult to align each elastic pin 101 with the flat pin 201, so the multiple first positioning columns 102 and the second positioning columns 202 can solve this problem. For example, first fix the second connection module 2 so that the first first positioning column 102 is aligned with the second positioning column 202 that is paired with it. Since the first first positioning column 102 and the first second positioning column 202 are provided with a magnetic attraction anti-dropping mechanism 3, at this time, the first first positioning column 102 and the first second positioning column 202 are in a state of mutual adsorption, but can rotate relative to each other; then, with the paired second positioning column 202 as the axis, slightly rotate the first connection module 1 until the second first positioning column 102 and the second positioning column 202 that is paired with it are aligned. At this time, each elastic pin 101 and each flat pin 201 are basically aligned one by one, and then gently push the first connection module 1 and fix its position so that the elastic pin 101 and the flat pin 201 are effectively connected, that is, the connection between the first connection module 1 and the second connection module 2 is completed. Multiple first positioning columns 102 and second positioning columns 202 realize multi-point positioning of the connector, making the connector connection process more precise. The magnetic anti-detachment mechanism 3 prevents the first connection module 1 and the second connection module 2 from accidentally loosening during and after the electrical connection process by attracting the first positioning column 102 and the second positioning column 202 , thereby ensuring the reliability and durability of the electrical connection.

[0034] In one possible implementation, in order to better meet the needs of multi-channel signal transmission, integrate more probes, and further reduce the space occupied by the connector and realize the miniaturization of the connector, such as Figure 1 As shown, the plurality of elastic pins 101 can be arranged in multiple rows, and the plurality of flat pins 201 are arranged in one-to-one correspondence with the plurality of elastic pins 101 , that is, the plurality of flat pins 201 correspond to the arrangement of the plurality of elastic pins 101 .

[0035] In one possible implementation, in order to improve the reliability and stability of the connection between the first connection module 1 and the second connection module 2, at least two pairs of the first positioning columns 102 and the second positioning columns 202 are provided with a magnetic attraction anti-detachment mechanism 3, preferably, each pair of the first positioning columns 102 and the second positioning columns 202 is provided with a magnetic attraction anti-detachment mechanism 3. Figure 1When the two groups of first positioning posts 102 and second positioning posts 202 are both provided with magnetic anti-slip mechanisms 3, the two magnetic anti-slip mechanisms 3 magnetically fix the two groups of positioning posts of the connector respectively, and the anti-slip effect of multi-point fixation is better than that of single-point fixation.

[0036] As a possible implementation mode, the magnetic attraction anti-detachment mechanism 3 includes a first magnet 301 and an iron sheet 302, wherein the first magnet 301 is fixedly arranged on the end face of the first positioning column 102, and the iron sheet 302 is fixedly arranged on the end face of the second positioning column 202; or, the first magnet 301 is fixedly arranged on the end face of the second positioning column 202, and the iron sheet 302 is fixedly arranged on the end face of the first positioning column 102; when the first positioning column 102 is positioned and matched with the second positioning column 202, the first magnet 301 and the iron sheet 302 are attracted to each other.

[0037] The first magnet 301 attracts the iron sheet 302 , so that the end surface of the first positioning column 102 and the end surface of the second positioning column 202 are firmly attracted to each other, thereby effectively preventing the connector from falling off.

[0038] As another possible embodiment, the magnetic anti-slip mechanism 3 includes a first magnet 301 and a second magnet 303, and the first magnet 301 and the second magnet 303 are connected to the first positioning column 102 and the second positioning column 202 in a one-to-one correspondence; when the first positioning column 102 and the second positioning column 202 are positioned and matched, the first magnet 301 and the second magnet 303 are attracted to each other.

[0039] Since magnets have the property of like charges repelling each other and opposite charges attracting each other, the end surface of the first positioning post 102 and the end surface of the second positioning post 202 are more firmly attracted together under the action of the first magnet 301 and the second magnet 303 with opposite magnetic properties, thereby improving the anti-dropping effect of the connector.

[0040] In one possible implementation, Figure 3 As shown, the elastic pin 101 includes a telescopic head 1011, an inner syringe 1012 and an outer syringe 1013 which are coaxially sleeved in sequence from the inside to the outside, the telescopic head 1011 is slidably connected to the inner wall of the inner syringe 1012 within a set range, and the inner syringe 1012 is slidably connected to the inner wall of the outer syringe 1013 within a set range; the end of the outer syringe 1013 away from the telescopic head 1011 is set as a spring pin terminal 10131, and a spring 1014 is provided in the inner syringe 1012, one end of the spring 1014 is abutted against the terminal of the outer syringe 1013, and the other end of the spring 1014 is abutted against the end of the telescopic head 1011.

[0041] More specifically, for example, the radial dimension of the elastic needle terminal 10131 on the outer syringe 1013 is smaller than the radial dimension of the inner wall of the outer syringe 1013, and the inner syringe 1012 can slide along the cavity in the outer syringe 1013; the end of the outer syringe 1013 away from the elastic needle terminal 10131 is provided with a first limiting edge, and the first limiting edge is used to limit the maximum sliding stroke of the inner syringe 1012; similarly, the telescopic head 1011 is provided in the cavity in the inner syringe 1012 and can slide along the inner wall of the inner syringe 1012, and the end of the inner syringe 1012 away from the elastic needle terminal 10131 is provided with a second limiting edge, and the second limiting edge cooperates with the telescopic head 1011 to limit the maximum sliding stroke of the telescopic head 1011. The spring 1014 is a telescopic spring 1014, which is provided in the inner syringe 1012 and can be telescopic along the axial direction of the inner syringe 1012. When the telescopic head 1011 contracts under axial pressure, the spring 1014 is compressed synchronously, and the telescopic head 1011 and the inner syringe 1012 slide close to the inner wall of the outer syringe 1013; when the pressure on the telescopic head 1011 is released, the spring 1014 stretches and pushes the inner syringe 1012 and the telescopic head 1011 to their respective maximum travels. The structural setting of the elastic pin 101 makes the elastic pin 101 have a certain buffering performance during the docking process with the flat pin 201, preventing the probe from bending under force and affecting the subsequent electrical connection effect; at the same time, due to the elasticity of the elastic pin 101, the telescopic head 1011 is only pressed against the flat pin 201, making its connection with the flat pin 201 more reliable and highly resistant to vibration.

[0042] In one possible implementation, Figure 2 and Figure 3 As shown, the end of the flat pin 201 facing away from the elastic pin 101 is set as a flat pin terminal 2012, and the end of the flat pin 201 facing the elastic pin 101 is provided with a pit 2011, and the pit 2011 is matched with the end of the elastic pin 101. In the process of connecting the elastic pin 101 and the flat pin 201, the pit 2011 has a guiding and positioning effect on the end (retractable head 1011) of the elastic pin 101, which can improve the docking efficiency and prevent the end of the elastic pin 101 from slipping off the end of the flat pin 201 after electrical connection, thereby improving the reliability of electrical connection.

[0043] Since the wiring side structure of the first connection module 1 is symmetrical to the wiring side structure of the second connection module 2, Figure 4 The structure shown is a schematic diagram of the wiring side structure of the first connection module 1 or the wiring side structure of the second connection module 2. Figure 4As shown, the spring pin terminals 10131 on the multiple elastic pins 101 are connected to the multiple signal lines 5 in a one-to-one correspondence, or the flat pin terminals 2012 on the multiple flat pins 201 are connected to the multiple signal lines 5 in a one-to-one correspondence, thereby realizing multi-channel signal transmission of the clamp.

[0044] In order to facilitate the installation and positioning of connectors on industrial equipment, such as Figure 1 and Figure 2 As shown, the first connection module 1 and the second connection module are respectively provided with mounting posts 4 for positioning the connector during installation.

[0045] The utility model provides an integrated multi-pin signal transmission connector, which is particularly suitable for application scenarios that integrate a large number of signal transmission probes. After a large number of signal transmission probes are integrated, the precise positioning of the probes is a difficult problem when the connector is electrically connected. After multiple probes are connected, the connection stability is also a problem that needs to be solved. Therefore, the utility model uses multiple groups of first positioning columns 102 and second positioning columns 202 that are arranged in pairs. Preliminary positioning is first performed through the first group of first positioning columns 102 and second positioning columns 202, and then precise positioning is performed through other groups of first positioning columns 102 and second positioning columns 202, thereby achieving the purpose of precise docking between a large number of elastic pins 101 and flat pins 201. At the same time, due to the setting of the magnetic suction anti-detachment mechanism 3, the reliability and stability of the connector during the docking process and after the electrical connection can be improved. The connector provided by the utility model has a simple structure, high reliability, low cost, and convenient installation.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
