Description

A quick-connect kit Technical Field

[0001] This application relates to the field of connector technology, and more specifically to a quick-connect kit. Background Technology

[0002] In the electrical control equipment at tobacco sites, there are a large number of analog signal detection devices. These devices are divided into three different wiring methods: two-wire, three-wire, and four-wire. Similarly, the input modules of PLCs are also divided into three types: two-wire, three-wire, and four-wire.

[0003] In the traditional approach, there are two solutions for detectors with different wiring methods:

[0004] Option 1: For analog signal detection devices with different wiring systems, use the corresponding PLC input module with the appropriate wiring system. This wiring method has the following disadvantages: 1. Three different PLC analog signal modules need to be configured on site, resulting in a complex spare parts configuration. When the device is changed (e.g., from 4-wire to 2-wire, or from 2-wire to 3-wire), the PLC module must also be replaced accordingly, involving a series of tasks such as program modification and hardware configuration, which increases the difficulty and risk of maintenance; 2. Each device change involves significant wiring modifications, which can easily lead to incorrect wiring.

[0005] Option 2: For analog signal detection devices with different wiring systems, all PLC input modules are configured with a 4-wire connection. This wiring method has the following disadvantages: 1. Although the PLC module can be uniformly configured as a 4-wire system, the terminal blocks on the module end do not correspond one-to-one with the terminal blocks on the detection device. When the device is changed, the technical skills required of the maintenance electrician are higher, and incorrect wiring is prone to occur; 2. When the device is changed, the wiring modifications involve both the device end and the module end, resulting in a larger workload and increased work risk. Summary of the Invention

[0006] The purpose of this application is to provide a quick-connect kit to solve the defect in the prior art that analog signal detection devices are prone to miswiring when switching between different wiring methods.

[0007] To achieve the above objectives, this application employs the following technical solution:

[0008] A quick-connect kit includes a module end plug and multiple detection end plugs, each detection end plug having a different number of connection ports; the multiple detection end plugs are connected to the module end plug.

[0009] The module end plug and each of the detection end plugs can be plugged in and fixed. The module end plug is provided with a buckle, and the detection end plug is provided with a locking member. The module end plug and the detection end plug are fixed together. The buckle and the locking member are used to prevent the module end plug and the detection end plug from moving out after plugging in.

[0010] In a further embodiment of this application, the module end plug is provided with a connection socket or a connection pin, and the detection end plug is provided with a connection pin or a connection socket, the connection socket and the connection pin are opposite to each other, and the connection pin is placed in the connection socket.

[0011] In a further embodiment of this application, a second guide is provided on the insertion surface of the module end plug, and a second guide groove is provided on the insertion surface of the detection end plug. The second guide moves along the depth direction of the second guide groove to guide the module end plug and the detection end plug.

[0012] In a further embodiment of this application, a first guide groove is provided on the insertion surface of the detection end plug, and the first guide groove matches the latch.

[0013] In a further embodiment of this application, there are two latches, which are symmetrically disposed on the outer wall of the module end plug.

[0014] In a further embodiment of this application, the locking component includes a linearly integrated force-applying section, an intermediate section, and a locking section. The intermediate section is fixed to the detection end plug by a support rod. The locking section is located near the latch. The module end plug is fixed to the detection end plug, and the locking section cooperates with the latch.

[0017] In a further embodiment of this application, the connection port includes a wiring terminal and a snap-fit ​​port, wherein the wiring terminal and the snap-fit ​​port are arranged vertically.

[0018] The beneficial effects of this application are as follows:

[0019] This application features a detection end plug that adapts to multiple module end plugs.

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use. Embodiments

[0031] As shown in Figures 1 to 3, this embodiment discloses a quick-connect kit, which includes a module end plug 2 and a detection end plug 1. In this embodiment, the detection end plug 1 has two data connection ports for connecting data cables. The module end plug 2 is uniformly set to have four data connection ports. The detection end plug 1 is compatible with the module end plug 2. Both the module end plug 2 and the detection end plug 1 can be plugged in and fixed. The module end plug 2 is provided with a latch 26, and the detection end plug 1 is provided with a locking member 15. The module end plug 2 and the detection end plug 1 are fixed. The latch 26 cooperates with the locking member 15 to limit the movement and ensure a stable connection between the module end plug 2 and the detection end plug 1. The latch 26 and the locking member 15 restrain each other to prevent the two plug ends from coming out. Figure 6 shows the state after the module end plug 2 and the detection end plug 1 are combined.

[0032] The module end plug 2 is provided with a connection socket 21, and the detection end plug 1 is provided with a connection pin 12, which is placed inside the connection socket 21.

[0033] As shown in Figures 1 and 3, in this embodiment, the plug surface of the module end plug 2 is provided with a second guide member 22, and the plug surface of the detection end plug 1 is provided with a second guide groove 14. When the module end plug 2 and the detection end plug 1 are fixed, the second guide member 22 moves along the depth direction of the second guide groove 14 to guide the module end plug 2 and the detection end plug 1. In view of the existence of the latch 26, to ensure the matching degree of the two plugs, the plug surface of the detection end plug 1 is provided with a first guide groove 13, which matches the latch 26.

[0034] In a further embodiment, the number of latches 26 is preferably two, and the two latches 26 are symmetrically arranged on the outer wall of the module end plug 2. At the same time, the number and position of the latches 26 and the first guide groove 13 are also matched with each other. The two latches 26 correspond to two locking members 15. The symmetrical locking members 15 fix the adjacent latches 26, which improves the stability of the connection between the two plugs and prevents the skew stress caused by a single set of locking members 15 and latches 26.

[0035] Specifically, as shown in Figure 4, the locking member 15 in this embodiment includes a linearly and integrally manufactured force-applying section 151, an intermediate section 152, and a locking section 153. The force-applying section 151 is used for the operator's hand to apply force, the intermediate section 152 serves as a transition, and the locking section 153 moves to cooperate with the latch 26. At this time, the locking section 153 is positioned closer to the latch 26, and the intermediate section 152 is fixed to the detection end plug 1 by a support rod. The locking member 15 and the support rod are made of elastic material.

[0036] In use, when the module end plug 2 and the detection end plug 1 are connected, they are guided by the second guide groove 14 and the first guide groove 13, and they make stable and gradual contact. During the process, the latch 26 and the locking section 153 contact and move relative to each other. When the latch 26 and the locking section 153 cross the critical position, the latching effect is achieved, the module end plug 2 and the detection end plug 1 are fixed, and the locking section 153 cooperates with the latch 26.

[0037] In a further embodiment, a first guide surface is provided on the locking section 153, and a second guide surface is provided on the latch 26. The second guide surface matches the first guide surface, and the first and second guide surfaces are mutually matching inclined surfaces. When the latch 26 and the locking section 153 are fixed, the operator can appropriately press the force application section 151 of the locking member 15 to speed up the connection and reduce the difficulty of insertion. If necessary, a connection mark 25 can be provided at the connection port of the module end plug 2 and the detection end plug 1. The conspicuous mark facilitates the operator's connection.

[0038] The module-side plug 2 and the detection-side plug 1 use conventional connection ports, including terminal blocks 23 and crimping ports 24. The terminal blocks 23 and crimping ports 24 are positioned vertically; specific details are prior art and will not be elaborated here. Example

[0039] As shown in Figure 5, in this embodiment, the detection end plug 1 is provided with three data connection ports. The connection structure between the detection end plug 1 and the module end plug 2 in this embodiment is the same as that in Embodiment 1. Embodiment

[0040] As shown in Figure 6, in this embodiment, the detection end plug 1 is provided with four data connection ports. The connection structure between the detection end plug 1 and the module end plug 2 in this embodiment is the same as that in Embodiment 1.

[0041] Except for the parts requiring electrical connection, all other parts of the quick-connect kit are made of insulating material. All electrical connection parts between the module end plug 2 and the detection end plug 1 adopt a recessed design to avoid the risk of short circuits and electric shock.

[0042] Specific usage:

[0043] This quick-connect kit enables rapid connection between the module end plug 2 and the detection end plug 1, allowing for quick replacement of multiple detection end plugs 1 and module end plugs 2. The connection ports on each detection end plug 1 are pre-set to avoid misconnection of signal lines.

[0044] Each set of analog detector quick-connect kits consists of one module end plug 2 and three different types of detector end plugs 1. The detector end plugs are available in two-wire, three-wire, and four-wire configurations.

[0045] When using the quick-connect kit, PLC modules can be uniformly configured as four-wire analog modules. Backward compatibility can be achieved through the kit, avoiding the need to modify programs, hardware configurations, and settings when replacing components.

[0046] The wiring of the PLC analog module should be connected to the M+, M-, L+, and L- marked on the back of the quick-connect kit module plug 2 according to the function. The wiring method is crimp-type, which can realize quick disconnection and disconnection.

[0047] Select the appropriate detector plug according to the type of analog detection device: use two-wire detection plug 1 for two-wire analog detectors, use three-wire detection plug 1 for three-wire analog detectors, and use four-wire detection plug 1 for four-wire analog detectors.

[0048] The wiring of the analog quantity detection device is directly connected to the corresponding markings on the back of the detection end plug 1 of the quick-connect kit according to its function. The wiring method is crimp-type, which can realize quick disconnection and disconnection.

[0049] After wiring the module and device ends respectively, simply plug the module end plug 2 into the detection end plug 1 to complete the normal use and realize the normal acquisition of analog quantities without the need for circuit modification;

[0050] The connector kit features a design to prevent incorrect wiring. As long as the module end and device end are wired according to the corresponding markings, the signal lines and power lines can be connected correctly.

[0051] The module end and the device end are locked on both sides by clamping to ensure a reliable circuit connection. When disassembling the connector, simply press the tail end of the locking piece 15 on both sides to release the interlocking state.

[0052] It is worth noting that while using this quick-connect kit, it is still necessary to ensure that the signal acquisition type and acquisition range of the PLC analog input module are consistent with the detector. This should also be noted when replacing the detector, as the quick-connect kit cannot convert between detectors and input modules with different signal acquisition types and acquisition ranges.
