Description

[0002] Industrial control products usually need to connect multiple circuit boards to form a complete controller, or make different functions into a single module. According to different requirements in actual use, the main module is extended to connect other functional modules. The connection between modules usually uses cable connection or terminal connection to establish a signal connection between each module.
[0003] The connection method between the main module and other expansion modules can also be divided into that all expansion modules are respectively connected to the main module, or one expansion module is connected to the main module, and then other expansion modules are successively connected to the previous expansion module. There are usually many signals that need to be connected between different modules. Cable connection is troublesome and requires a large space, while terminal connection can quickly plug in multiple signals and requires a smaller space. In related technical means, most of the existing terminals are mainly in the form of male-female direct insertion, which limits the module to be plugged and unplugged only perpendicular to the terminal surface. When using the method of connecting all expansion modules to the main module respectively, it will seriously affect the heat dissipation and operation of the module, and the space utilization rate is not high, and the number of expansion modules that can be added is also very limited. When using the method of connecting expansion modules successively to the previous expansion module, although it does not affect heat dissipation and operation, when multiple modules are arranged and connected using terminals in a direct insertion manner, when repairing and replacing the previous module, all the subsequent modules need to be moved, increasing the difficulty and required space for repair and replacement.
[0004] In view of the above technical means, when multiple modules are successively connected, there are defects that a large space is required to disconnect the connection between the terminals, and the repair and disassembly are complicated. Summary of the Utility Model

[0034] The following further describes the present application in detail with reference to the accompanying drawings.
[0035] The embodiment of the present application provides a terminal and a communication power supply module, which can make the maintenance and disassembly of the terminals between adjacent two modules simple when multiple modules are connected in sequence, and only the middle module needs to be replaced without moving other modules, reducing the space required for installation and maintenance.
[0036] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions appears to be mutually contradictory or unable to be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present application.
[0037] In the description, claims and the above-mentioned drawings of the present invention, terms such as "first", "second", "third", "fourth", etc. are used to distinguish similar objects and do not necessarily describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances so that the embodiments described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device comprising a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.
[0038] Industrial control products usually need to connect multiple circuit boards 2 together to form a complete controller, or make different functions into a single module. According to different requirements in actual use, the main module is extended to connect to other functional modules. The connection between modules usually uses cable connection or terminal connection to establish a signal connection between each module.
[0039] The connection method between the main module and other expansion modules can also be divided into that all expansion modules are respectively connected to the main module, or one expansion module is connected to the main module, and then other expansion modules are sequentially connected to the previous expansion module. There are usually many signals that need to be connected between different modules. Cable connection is troublesome and requires a large space, while terminal connection can quickly plug in multiple signals and requires a smaller space. In the related technical means, most of the existing terminals are mainly in the form of male-female straight plug, which limits the modules to be plugged and unplugged only on the vertical terminal surface. When using the method of connecting all expansion modules to the main module respectively, it will seriously affect the heat dissipation and operation of the modules, and the space utilization rate is not high, and the number of expansion modules that can be increased is very limited. When using the method of connecting expansion modules to the previous expansion module in sequence, although it does not affect heat dissipation and operation, and there is even a possibility of infinitely connecting expansion modules in terms of structure, when multiple modules are arranged and connected using terminals in the straight plug manner, when repairing and replacing the previous module, all the subsequent modules need to be moved, which increases the difficulty and the required space for repair and replacement.
[0040] The expansion modules are connected to the previous expansion module in sequence. When repairing or replacing the previous module, all the subsequent modules need to be moved because there is only one direction for the insertion and extraction actions between the male and female connectors of the connection terminals. If the insertion direction is downward, the extraction direction is upward. Taking any three adjacent modules connected in sequence from left to right as an example, the position where the previous module connects to the middle module uses a female connector, the position where the middle module connects to the previous module uses a male connector, then the position where the middle module connects to the subsequent module uses a female connector, and correspondingly, the position where the subsequent module connects to the middle module uses a male connector. When the connection terminals are used on the vertical side, and the insertion and extraction directions are left and right respectively, it is inevitable to move the module on the left or right when replacing the middle module. When the connection terminals are used on the parallel side, when replacing the middle module, the previous module remains stationary, and the middle module needs to be pulled out upward so that the male connector of the middle module is disengaged from the female connector of the previous module, completing the disconnection between the two modules. However, when the middle module is pulled out upward, the relative direction between the female connector of the middle module and the male connector of the subsequent module is the direction in which they are inserted tightly, so pulling out the middle module will drive the subsequent module, and so on. Therefore, when using this type of straight plug connection terminal, replacing the middle module requires moving all the subsequent modules.
[0041] To solve this problem, it is necessary to change the insertion and extraction directions of the male and female connectors of the terminal so that the male connector and / or the female connector can be inserted and extracted horizontally with respect to the adjacent female connector and / or male connector, thereby solving the above problem. For ease of understanding, the terminal and the communication power supply module in the embodiments of the present application will be described below. Please refer to Figure 1 , which is an embodiment of an industrial control product in the embodiments of the present application. The industrial control product includes a plurality of communication power supply modules arranged in parallel. The plurality of modules are electrically connected in sequence, and two adjacent communication power supply modules are slidably connected, facilitating the removal of the middle module that needs to be replaced, thereby achieving the effect of not moving other modules, making the repair and disassembly simple, reducing the difficulty of repair and replacement, and realizing fast repair and replacement.
[0042] Please refer to Figure 2 and Figure 3 , which is an embodiment of the communication power supply module in the embodiments of the present application, including a housing 1, a circuit board 2, and a terminal 3. The housing 1 is hollow, the circuit board 2 is disposed inside the housing 1, and the terminal 3 is electrically connected to the circuit board 2. The terminal is used for transmitting signals and realizing electrical connection between adjacent modules.
[0043] The housing 1 includes a first housing body 11 and a second housing body 12 which are detachably connected. When two adjacent housings 1 are fitted together, the first housing body 11 is slidably connected to the second housing body 12 in another housing 1 so that the two adjacent housings 1 are connected. Specifically, slide rails 112 are provided at opposite ends of the first housing body 11, and slide grooves 122 are provided at opposite ends of the second housing body 12. The length directions of the slide rails 112 and the slide grooves 122 are the same. The slide rails 112 are located at the upper and lower ends of the first housing body 11, and the slide grooves 122 are located at the upper and lower ends of the second housing body 12. When two adjacent housings 1 are fitted together, the slide rails 112 on the first housing body 11 can be slidably connected to the slide grooves 122 on the second housing body 12 in another housing 1, so that the two adjacent housings 1 are snap-connected. In this embodiment, the first housing body 11 and the second housing body 12 are detachably connected by snap connection. In other embodiments, the first housing body 11 and the second housing body 12 can also be detachably connected by forms such as bolts and plug-in connections.
[0044] Please refer to Figure 5 and Figure 6 , the terminal includes a base 31, a first elastic piece 33 and a second elastic piece 34. The first elastic piece 33 and the second elastic piece 34 are parallel and are respectively electrically connected to the circuit board 2 for transmitting different signals respectively. The first elastic piece 33 is equivalent to a male head, and the second elastic piece 34 is equivalent to a female head. In the same module, one end of the first elastic piece 33 and one end of the second elastic piece 34 both penetrate through the housing 1 and are located on both sides of the housing 1. Between adjacent modules, the first elastic piece 33 in one module contacts and is electrically connected to the second elastic piece 34 in another module, so that the electrical connection between adjacent modules can be realized.
[0045] Please refer to Figure 1 and Figure 2 , the first housing body 11 is provided with a first mounting hole 111 corresponding to the first elastic piece 33, and one end of the first elastic piece 33 penetrates through the first mounting hole 111 and is located outside the housing body; the second housing body 12 is provided with a second mounting hole 121 corresponding to the second elastic piece 34, and a groove 123 is provided on the second housing body 12. The length direction of the groove 123 is the same as the sliding direction of the housing 1, and the end of the groove 123 is communicated with the second mounting hole 121 to guide the first elastic piece 33 when connecting to another module. When two adjacent housings 1 are fitted together, the first elastic piece 33 is slidably fitted with another housing 1 so that the first elastic piece 33 is electrically connected to the second elastic piece 34 in another module along the sliding direction of the housing 1.
[0046] When it is necessary to take out the module that needs to be replaced in the middle, the first shell 11 and the second shell 12 of the module to be replaced are displaced from the adjacent modules respectively through the slide rail 112 and the slide groove 122. At this time, the first spring clip 33 slides from the second mounting hole 121 to the groove 123, the first spring clip 33 is separated from the second spring clip 34, and the electrical connection between the two is disconnected. The first spring clip 33 slides along the groove 123; when the slide rail 112 is disengaged from the slide groove 122, the module to be replaced is disengaged from between the modules.
[0047] See also Figure 3 and Figure 4 The circuit board 2 is installed and fixed by the hooks and mounting posts provided on the first housing 11 and / or the second housing 12. The base 31 is fixedly installed on the circuit board 2. Specifically, the terminal 3 also includes a fixing post 32. The base 31 is provided with a clamping groove for the fixing post 22 to pass through. The fixing post 32 is generally arranged in a "冂" shape. The fixing post 32 is parallel to the end surface of the base 31 and presses against the base 31. The end of the fixing post 32 passes through the clamping groove and is fixed to the circuit board 2. In this embodiment, the end of the fixing post 32 is welded to the circuit board 2.
[0048] Furthermore, the base 32 is also provided with a positioning column 312, which is arranged perpendicular to the circuit board 2, one end of the positioning column 312 is integrally formed with the base 31, and the other end of the positioning column 312 passes through the circuit board 2, and the positioning column 312 guides and positions the base 31 when it is installed on the circuit board 2. In this embodiment, the positioning column 312 and the base 31 are both made of plastic material, and two positioning columns 312 are provided, and the two positioning columns 312 are respectively arranged on the left and right sides of the base 31 to enhance the stability of the base 31.
[0049] See also Figure 5 The base 31 is provided with mounting grooves for mounting the first spring piece 33 and the second spring piece 34, and the mounting grooves are not connected to each other, so that in the same module, the first spring piece 33 and the second spring piece 34 are not connected. The terminals 3 are provided in multiple groups and arranged in parallel, and the base 31 is provided with isolation walls 311 for isolating each group of terminals 3, and each group of terminals 3 is located between two isolation walls 311.
[0050] See also Figure 5 , Figure 6 and Figure 7, the first elastic piece 33 and the second elastic piece 34 are both arranged on the base 31, and the materials of the first elastic piece 33 and the second elastic piece 34 are conductive metals. The first elastic piece 33 is generally sheet-shaped. The first elastic piece 33 includes a first body 331, a first pin 332, and a first leg 333. The first pin 332 and the first leg 333 are obtained by stamping and cutting parts of the first body 331. The first pin 332 is located at one end of the first body 331 and is electrically connected to the circuit board 2. The first leg 333 is bent and arranged, and is inserted into the base 31 and fixed on one side of the first body 331. One end of the first body 331 away from the first leg 333 passes through the first mounting hole 111 and is located outside the first housing 11.
[0051] The second elastic piece 34 includes a second body 341, a second pin 342, and a second leg 343. The second pin 342 and the second leg 343 are both located at one end of the second body 341. The second elastic piece 34 is formed by stamping a piece of conductive metal material; the second pin 342 is electrically connected to the circuit board 2, and the second leg 343 is inserted into the base 31 and fixed. In this embodiment, the first pin 332 and the second pin 342 are both arranged on the same side of the circuit board 2 and are welded to the circuit board 2. The first pin 332 and the second pin 342 are both arranged on the same side of the circuit board 2, which reduces the structural parts of the terminal and simplifies the steps and difficulty of welding the first pin 332 and the second pin 342 to the circuit board 2.
[0052] Please refer to Figure 7 , one end of the second body 341 away from the second leg 343 is a clamping portion 3411. The clamping portion 3411 is close to the side wall of the housing 1, and the clamping portion 3411 is arranged corresponding to the second mounting hole 121; the clamping portion 3411 is used for clamping the first elastic piece 33 in another module. The clamping portion 3411 is composed of two elastic arms 3412. The two elastic arms 3412 are located on both sides of the plane where the first elastic piece 33 is located and are symmetrically arranged. Along the direction gradually away from the second leg 343, the distance between the two elastic arms 3412 gradually decreases to clamp the first elastic piece 33 in another module. By reducing the distance between the two elastic arms 3412, the arrangement of the elastic arms 3412 enhances the connection stability between the second elastic piece 34 and the first elastic piece 33 in another module.
[0053] Furthermore, protrusions 3413 are provided on the end faces of the two elastic arms 3412 facing each other. The two protrusions 3413 are arranged oppositely, and the two protrusions 3413 jointly clamp the first elastic piece 33 of another module. Along the sliding direction of the housing 1, the distance between the two elastic arms 3412 gradually decreases and then gradually increases. A guiding space 3414 is formed by the two elastic arms 3412 surrounding both sides of the protrusion 3413, which is used to guide the first elastic piece 33 to the protrusion 3413 when the first elastic piece 33 slides to the clamping portion 3411. The protrusion 3413 further enhances the connection stability between the second elastic piece 34 and the first elastic piece 33 in another module, so as to ensure that when the second elastic piece 34 is connected to the first elastic piece 33 in the adjacent module, the second elastic piece 34 and the first elastic piece 33 in the adjacent module can maintain electrical connection even under a small acting force. When it is necessary to install the repaired module, the first elastic piece 33 moves along the length direction of the groove 123 into the second mounting hole 121 in the adjacent module. Under the action of the guiding space 3414, the first elastic piece 33 moves towards the protrusion 3413. The clamping portion 3411 of the first elastic piece 33 and the second elastic piece 34 in the adjacent module clamps under the action of the protrusion 3413, so that the first elastic piece 33 contacts and is electrically connected to the second elastic piece 34 in the adjacent module, thereby realizing the fixation and electrical connection between adjacent modules.
[0054] When it is necessary to take out the module that needs to be replaced in the middle, through the slide rail 112 and the chute 122, the first housing 11 and the second housing 12 of the module to be replaced are displaced from the adjacent modules respectively. At this time, the first elastic piece 33 slides from the second mounting hole 121 to the groove 123, and the first elastic piece 33 is separated from the second elastic piece 34, disconnecting the electrical connection between the two. The first elastic piece 33 slides along the groove 123. When the slide rail 112 is separated from the chute 122, the module to be replaced is separated from between the modules, thus achieving the effect of taking out the module to be replaced without moving other modules, and the required space is small. When it is necessary to install the repaired module, the slide rail 112 on the first housing 11 of the repaired module is matched with the chute 122 on the second housing 12 of the adjacent module. At the same time, the chute 122 on the second housing 12 of the repaired module is matched with the slide rail 112 on the first housing 11 of the adjacent module, and moves along the sliding direction under the acting force. At this time, the first elastic piece 33 also moves along the length direction of the groove 123 into the second mounting hole 121 to contact and be electrically connected to the second elastic piece 34, thereby realizing the fixation and point connection between adjacent modules.
