Description

Technical Field

[0001] This utility model applies to the field of electrical connection technology, and in particular relates to a double-layer plug-in wall terminal base. Background Technology

[0002] In current electrical system design, especially in highly integrated modular systems, signal transmission and power connections between different unit modules typically require through-wall connectors. However, existing through-wall connector solutions have several limitations and shortcomings.

[0003] Currently, the commonly used 3.81mm and 5.08mm pitch through-wall connector bases on the market generally adopt a single-layer design. When the electrical system requires a large number of signal cables, such as 24-bit signals, the panel length occupied by a single-layer connector increases significantly, reaching approximately 145mm. In highly integrated modular enclosure designs, this longer connector length can easily cause spatial interference with the interfaces of other devices, while also increasing the complexity and inconvenience of installation and maintenance. Furthermore, for some compact devices or applications with limited space, single-layer connectors cannot meet the requirements for efficient space utilization.

[0004] To solve the above-mentioned technical problems, this utility model designs a double-layer plug-in wall terminal base. Utility Model Content

[0005] This utility model provides a double-layer plug-in wall terminal base, which aims to solve the problems of existing single-layer wall connectors occupying a large space in highly integrated systems, causing space interference due to long panel length, and failing to make efficient use of space in compact spaces.

[0006] A double-layer plug-in wall terminal block base includes a mounting housing and a terminal block assembly detachably connected to the mounting housing;

[0007] The terminal assembly includes a terminal module, an internal conductive component, and terminal pins. The terminal module includes an upper terminal group and a lower terminal group, each including multiple terminals for connecting wires. The internal conductive component is disposed within the terminal module, and the terminal pins are disposed on the terminal module for electrical connection with the external pins of an external plug. The internal conductive component electrically connects the terminal pins to the wires in the terminal module to form an electrical path from the external plug through the terminal pins and the internal conductive component to the wires.

[0008] Based on the above technical solution, a sliding groove is provided on the mounting housing, and the identification strip is slidably connected in the sliding groove.

[0009] Based on the above technical solution, the terminal block module is a spring-loaded direct-insertion terminal block module. The first end cover of the spring-loaded direct-insertion terminal block module is fastened to the mounting housing. The spring-loaded direct-insertion terminal block module has an upper terminal block group and a lower terminal block group. Both the upper terminal block group and the lower terminal block group are provided with a first insertion hole and a spring button. Pressing the spring button can control the spring in the first insertion hole to move to realize the insertion or removal of the wire.

[0010] Based on the above technical solution, the internal conductive component includes a first conductor mounting bracket, a conductor strip, and a contact block; the first conductor mounting bracket is provided with a slot, and the conductor strip is fitted into the slot; one end of the conductor strip is electrically connected to the terminal block pin by welding or crimping, and the other end is in elastic contact with a spring contact; the contact block is connected to a spring button and is used to transmit the operating force of the spring button to the spring contact in the first insertion hole, so as to form a conductive path from the terminal block pin to the wire in the insertion hole.

[0011] Beneficial effects

[0012] Compared with existing technologies, the advantages of this utility model are: 1. This device adopts a double-layer structure design, which can accommodate more terminals within the same panel length compared to traditional single-layer through-wall connectors. In the highly integrated modular enclosure design, the double-layer structure reduces spatial interference with other device interfaces, making the overall system layout more compact and rational. 2. Both the spring-loaded direct-insertion terminal module and the cage-type screw terminal module provide convenient operation methods, allowing for wire insertion and removal without additional tools. This greatly simplifies the installation and maintenance process and improves work efficiency. Attached Figure Description

[0026] Example 1

[0027] This utility model provides a technical solution: a double-layer plug-in wall terminal base, including a mounting housing 1 and a terminal assembly detachably connected to the mounting housing 1;

[0028] The terminal assembly includes a terminal module, an internal conductive component, and a terminal pin 21. The terminal module includes an upper terminal group and a lower terminal group, each of which includes multiple terminals for connecting wires.

[0029] By arranging the terminal blocks in two layers, more wiring positions can be provided within a limited space, which is especially important for highly integrated electrical systems. For example, in situations where panel space is limited, a double-layer design can effectively reduce the overall size of the equipment.

[0030] The internal conductive component is disposed within the terminal block module, and the terminal pin 21 is disposed on the terminal block module for electrical connection with the external pin of the external plug. The internal conductive component electrically connects the terminal pin 21 to the wire in the terminal block module to form an electrical path from the external plug through the terminal pin 21, the internal conductive component to the wire.

[0031] An external plug is inserted into a terminal block pin 21 via its external pins, thereby establishing an electrical path that allows current or signals to be smoothly transmitted from one module to another.

[0032] like Figure 3 As shown, a sliding groove 22 is provided on the mounting housing 1, and the marking strip 4 is slidably connected in the sliding groove 22.

[0033] The markings on label 4 can include terminal block number, function description, voltage level, or color coding. Label 4 helps users quickly identify the function of each terminal block or the object being connected, improving work efficiency.

[0034] The mounting housing 1 is equipped with a protective cover that covers the entire terminal block module. This prevents external factors such as dust and moisture from affecting the terminal blocks, thereby improving the system's reliability and service life.

[0035] like Figure 1 As shown, the terminal block module is a spring-loaded direct-insertion terminal block module. The first end cap 53 of the spring-loaded direct-insertion terminal block module is fastened to the mounting housing 1. The spring-loaded direct-insertion terminal block module 5 has an upper terminal block group and a lower terminal block group. Both the upper terminal block group and the lower terminal block group are provided with a first insertion hole 51 and a spring button 52. Pressing the spring button can control the spring contact 34 in the first insertion hole 51 to move to realize the insertion or removal of the wire.

[0036] like Figure 5As shown, the internal conductive component includes a first conductor mounting bracket 31, a conductor strip 33, and a contact block 35; the first conductor mounting bracket 31 is provided with a slot, and the conductor strip 33 is fitted into the slot; one end of the conductor strip 33 is electrically connected to the terminal pin 21 by welding or crimping, and the other end is in elastic contact with the spring contact 34; the contact block 35 is connected to the spring button 52 and is used to transmit the operating force of the spring button 52 to the spring contact 34 in the first insertion hole 51, so as to form a conductive path from the terminal pin 21 to the wire in the insertion hole.

[0037] One end of the conductor strip 33 is securely electrically connected to the terminal block pin 21 by welding or crimping, while the other end is in elastic contact with the spring contact 34. This design ensures a low-resistance, high-stability electrical path from the external plug to the wire.

[0038] When the wire is inserted, the spring contact 34 will automatically clamp the wire to form a stable electrical connection.

[0039] By pressing the spring button 52 to control the action of the spring contact 34, the insertion or removal of wires can be easily achieved without the need for additional tools, greatly simplifying the wiring process.

[0040] Spring-loaded through-hole terminal modules are suitable for various types of wires, including solid and flexible wires, and support a wide range of wire cross-sectional areas to meet the needs of different application scenarios.

[0041] like Figure 4 As shown, when using the spring-loaded direct-insertion terminal module, the user presses the spring button 52, which transmits the operating force to the spring contact 34 via the contact block 35, temporarily releasing its clamping force on the wire. Using this gap, the wire is inserted into the first insertion hole 51 until it contacts the spring contact 34. Releasing the spring button 52 causes the spring contact 34 to return to its original position, automatically clamping the wire and ensuring it remains in contact with the conductor strip 33, forming a stable electrical connection. Current or signals enter the conductor strip 33 from the external plug through the terminal pins 21, and then through the wire, forming a complete electrical path.

[0042] If it is necessary to remove the wire, the user presses the spring button 52 again, which causes the spring contact 34 to release the clamping force on the wire through the contact block 35. The wire can then be easily removed, completing the disassembly operation.

[0043] The device's design conforms to the standard Phoenix terminal length and socket size, and is suitable for use with through-wall solderless plugs with two pitches: 3.81mm or 5.08mm. The panel height is 38mm, and the panel length can be adjusted accordingly based on different pitches (3.81mm or 5.08mm) and the number of interfaces.

[0044] Example 2

[0045] A double-layer plug-in wall terminal block base includes a mounting housing 1 and a terminal block assembly detachably connected to the mounting housing 1;

[0046] The terminal assembly includes a terminal module, an internal conductive component, and a terminal pin 21. The terminal module includes an upper terminal group and a lower terminal group, each including multiple terminals for connecting wires. The internal conductive component is disposed within the terminal module, and the terminal pin 21 is disposed on the terminal module for electrical connection with the external pins of an external plug. The internal conductive component electrically connects the terminal pin 21 to the wires in the terminal module to form an electrical path from the external plug through the terminal pin 21 and the internal conductive component to the wires.

[0047] The mounting housing 1 has a sliding groove 22, and the identification strip 4 is slidably connected in the sliding groove 22.

[0048] like Figure 6 As shown, the terminal block module is a cage screw terminal block module. The cage screw terminal block module includes an upper terminal block group and a lower terminal block group that are arranged in a stepped manner along the vertical direction. Both the upper terminal block group and the lower terminal block group are equipped with a second insertion hole 61 and a corresponding wire clamping screw 62. The wire is pressed into the second insertion hole 61 by turning the wire clamping screw 62.

[0049] By employing a stepped distribution design, the upper and lower terminal blocks are not on the same plane, thus providing more wiring positions within a limited space. This is especially important for highly integrated electrical systems. The stepped distribution not only reduces the overall footprint but also makes the panel layout more rational, avoiding mutual interference between different terminal blocks.

[0050] like Figure 7 and Figure 8 As shown, the internal conductive component includes a second conductor mounting bracket 60, a slot is provided on the second conductor mounting bracket 60, a slot conductor 601 is provided in the slot, the terminal pin 21 is electrically connected to the slot conductor 601, and the plug pin 63 is inserted into the slot and electrically connected to the slot conductor 601.

[0051] By tightening the wire clamping screw 62, the wire is pressed firmly into the second insertion hole 61, ensuring a tight contact between the wire and the terminal block and reducing the possibility of poor contact. The strong clamping force provided by the wire clamping screw can effectively resist mechanical vibration and impact, maintaining a long-term stable electrical connection, and is particularly suitable for applications with frequent vibration.

[0052] When using the cage screw terminal module, the slot conductor 601 is initially fixed in the slot of the second conductor mounting bracket 60, and the connector pin 21 is electrically connected to the slot conductor 601. The user inserts the pin 63 into the slot, and the pin 63 contacts the slot conductor 601, forming an electrical connection. Current or signals from the external plug enter the slot conductor 601 through the connector pin 21, and are then transmitted to the internal wires through the pin 63, forming a complete electrical path.

[0053] Strip the end of the wire, exposing an appropriate length, typically a few millimeters, for insertion into the second insertion hole 61. The stripped length should meet the requirements of the specific application to ensure good electrical contact. Insert the stripped wire into the corresponding second insertion hole 61, ensuring the wire is fully inserted into the insertion hole and reaches the position where it contacts the internal conductive components.

[0054] Initially, the wire clamping screw 62 is in the loose position, allowing the wire to be easily inserted into the second connector hole 61. Use a screwdriver to tighten the wire clamping screw 62, gradually pressing the wire downwards. As the screw tightens, its bottom will press against the wire, ensuring the wire is securely fixed in the second connector hole 61. When tightening the screw, pay attention to torque control; a torque of 0.4 N·m is generally recommended to ensure a secure hold without damaging the wire or the screw itself.

[0055] The conductor can be either solid or stranded. Solid wire has a cross-sectional area of ​​0.1-4 mm², while stranded wire has a cross-sectional area of ​​0.1-2.5 mm². Solid wire is typically used for power distribution and high-power loads, while stranded wire is mostly used for signal transmission and control circuits.

[0056] like Figure 3 As shown, the mounting housing 1 is provided with a mounting plate 7, and the mounting plate 7 has a first fixing hole 71 and a second fixing hole 72. Through the first fixing hole 71 and the second fixing hole 72, screws or other fasteners can be used to firmly fix the mounting housing 1 in the required position to ensure that it will not shift or loosen during use.

[0057] The mounting housing 1 utilizes either a removable spring-loaded through-hole terminal module or a cage-type screw terminal module. Users can choose the appropriate terminal module based on their specific application requirements. Spring-loaded through-hole terminal modules are suitable for scenarios requiring frequent wire insertion and removal, such as testing equipment or temporary wiring, significantly improving work efficiency. Cage-type screw terminal modules are suitable for long-term, stable electrical connections and scenarios where wire replacement is infrequent.

[0058] Each terminal block module can be disassembled and replaced independently, making system maintenance and upgrades more convenient. For example, if a module fails, it can be quickly replaced without affecting the operation of other parts.

[0059] The terminal blocks of the terminal block module are spaced at 3.81mm or 5.08mm. By providing two different spacing options (3.81mm and 5.08mm), a suitable spacing can be selected according to specific needs, thereby maximizing the use of available area within a limited space.

[0060] It should be noted that the terminal pins, spring contacts, etc. in this embodiment are all general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0061] The present invention has been described above by way of example, but the present invention is not limited to the specific embodiments described above. Any modifications or variations made based on the present invention shall fall within the scope of protection claimed by the present invention.
