Description

Technical Field

[0001] This invention relates to the field of terminal blocks, and more specifically to an adjustable and detachable terminal block and wiring device. Background Technology

[0002] Currently, starter and protector terminals mainly come in two specifications: 6.3mm and 4.8mm. Terminals and plugs of the same specification are interlocked. During experiments, circuit adjustments are frequently performed, which can easily lead to mismatches between plugs and terminals, requiring replacement of either the terminal or the plug. However, this replacement process is cumbersome and can easily cause breakage or damage at the connection points between the plug and the lead, or between the terminal and the lead. Loosening the terminals can also affect the connection's firmness, posing a risk of the terminals falling off.

[0003] In the prior art, a structure that facilitates disassembly and assembly is set between the terminal and the lead wire. When the plug and the terminal are incompatible, the connection requirements can be met by replacing the terminal that is compatible with the plug. However, this method still has the problem of poor reliability of the connection position. When the connection is frequently replaced, the conductivity stability is difficult to meet the requirements. In addition, the weak connection position will generate too much heat when the circuit is conducting, which may cause the circuit components to overheat and burn out, resulting in unstable circuit operation and affecting the debugging effect of the equipment. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing an adjustable and detachable terminal and wiring device. It features two side plates connected to a carrier plate, with at least one side plate movable relative to the carrier plate. The distance between the two side plates can be adjusted to change the size of the resulting plug portion and lock the position. This device is suitable for plugs of different specifications, eliminates the need to replace terminals, ensures a secure and reliable connection, enables stable circuit operation, and meets debugging requirements.

[0005] The first objective of this invention is to provide an adjustable and easily detachable terminal, which adopts the following solution:

[0006] include:

[0007] The carrier plate is provided with spaced sliding holes and buckles. One end of the sliding hole is provided with a spiral frame that communicates with it. Sliding grooves are respectively opened on a pair of opposite sides of the spiral frame. The buckle is provided with a protrusion on the side facing the spiral frame.

[0008] The side plate has two spaced-apart plates that are respectively connected to the carrier plate. The two side plates and the carrier plate together form a plug-in part that accommodates the plug. At least one side plate is slidably engaged with a sliding hole by a slider. The slider is connected to a sliding rod. The sliding rod is slidably engaged with a set of opposite sliding grooves of the U-shaped frame.

[0009] The locking buckle, connected to the slide bar, is used to lock or unlock the relative position of the side panel and the carrier plate in conjunction with the U-shaped frame.

[0010] Furthermore, the side plate has an L-shaped cross-section, and the buckle is located between the two side plates. The protrusion of the buckle is located on the side opposite to the insertion part. The slide rod and slider move relative to the sliding hole to adjust the distance between the two side plates.

[0011] Furthermore, the spiral frame protrudes from the surface of the carrier plate, and the inner cross-section of the spiral frame is the same as the cross-section of the sliding hole. One end of the slider is connected to the side plate, and the other end passes through the sliding hole and is connected to the sliding rod.

[0012] Furthermore, the two ends of the slide rod slide in conjunction with the slide groove, and the locking buckle is connected to the slide rod segment inside the loop frame; a spring is provided between one side of the slide rod and the loop frame, one end of the spring acts on the loop frame, and the other end abuts against the slide rod to maintain the position of the slide rod.

[0013] Furthermore, the inner walls of a set of opposite sides of the sliding groove of the U-shaped frame are respectively provided with locking holes, the distribution of the locking holes correspond to the positions of the side plate adapter plugs, and the locking buckle cooperates with the locking holes to lock.

[0014] Furthermore, the inner wall of the slide groove is provided with a guide groove, the distribution direction of the guide groove is consistent with the sliding direction of the side plate relative to the carrier plate, and the part of the slide rod located in the slide groove is connected with a guide pin, the guide pin and the guide groove are slidably engaged.

[0015] Furthermore, a pair of sidewalls in the slide groove are provided with guide grooves and guide pins respectively. The guide pins that are matched with the guide grooves in the same slide groove are connected to the same end of the slide rod.

[0016] Furthermore, one side of the buckle protrudes into the insertion part and acts as a stop block. The protrusion can be driven by external force to elastically deform the buckle, so that the stop block is in the insertion part or withdrawn from the insertion part.

[0017] A second object of the present invention is to provide a wiring device that utilizes an adjustable and detachable terminal as described in the first object.

[0018] Furthermore, the adjustable and detachable terminal and plug are respectively connected to lead wires, and the plug is inserted into the insertion part and locked in place by a snap-fit.

[0019] Compared with the prior art, the advantages and positive effects of this invention are:

[0020] (1) To address the problem that terminals and plugs of different specifications cannot be adapted during current circuit adjustment, two side plates are set up to connect to the carrier plate respectively. At least one side plate can move relative to the carrier plate, and the distance between the two side plates can be adjusted to change the size of the formed plug part and lock the position to adapt to plugs of different specifications. There is no need to replace the terminals, ensuring the firmness and reliability of the connection, realizing stable circuit operation, and meeting the debugging requirements.

[0021] (2) The side plate is connected to the slide rod by the slider. The two ends of the slide rod are respectively engaged with the slide groove to slide and position, thereby improving its stability. The side plate maintains its position to ensure the stability when the plug is engaged, so that the side plate has good engagement and positioning performance before and after adjusting the position of the side plate.

[0022] (3) The buckle is provided with a protrusion, and the protrusion is located on the side away from the plug. When the plug is replaced and the side plate spacing is adjusted to accommodate different plug specifications, the buckle can be operated through the protrusion. The buckle protrudes from the stop block inside the plug and retracts, so that the plug can be smoothly removed from the plug to avoid damaging the lead wire connection position.

[0023] (4) The slide groove constrains the movement of the side plate from both ends of the slide rod. The guide groove and guide pin are added to strengthen the connection between the slide rod and the loop frame. The guide pin can be an elastic retractable pin so that it can be retracted during installation, thereby improving the strength of the connection between the slide rod and the loop frame and thus improving the stability of the side plate before and after movement.

[0029] Example 1

[0030] In a typical embodiment of the present invention, such as Figures 1-3 As shown, an adjustable and detachable terminal is presented.

[0031] Terminals and plugs work together to establish circuit continuity. During equipment testing, the wiring positions need to be adjusted, which can lead to incompatibility between terminal and plug specifications. Traditional methods of replacing terminals and plugs are cumbersome and can easily damage the reliability of lead wire connections. Furthermore, the quick-release mechanisms between leads and terminals, and leads and plugs, suffer from insufficient stability. Repeated disassembly and replacement can result in weak connections, leading to overheating, damage, and other circuit problems, ultimately affecting circuit stability and equipment debugging effectiveness.

[0032] Based on this, this embodiment provides an adjustable and detachable terminal, which separates the carrier plate 1 from the side plate 2. The side plates 2 on both sides of the plug insertion position are independent. A sliding component is configured to establish the connection between the side plate 2 and the carrier plate 1. The side plate 2 can be adjusted relative to the carrier plate 1 and locked in position using a locking member, thereby achieving adjustment of the fitting size of the plug-in part 8 formed by the carrier plate 1 and the side plate 2, which facilitates wiring adjustment during equipment testing.

[0033] The adjustable and detachable terminal will now be described in detail with reference to the accompanying drawings.

[0034] See Figure 1 The adjustable and detachable terminal includes a carrier plate 1, side plates 2, and a locking buckle 10. The carrier plate 1 serves as the main load-bearing structure. The two side plates 2 are respectively connected to the carrier plate 1 to form a U-shaped structure, which together form a plug-in portion 8 to accommodate the plug. At least one side plate 2 is slidably engaged with the carrier plate 1. Adjusting the relative position of the carrier plate 1 and the side plate 2 changes the size of the plug-in portion 8 to accommodate plugs of different specifications. After adjusting the relative position of the side plate 2 and the carrier plate 1, the locking buckle 10 locks their positions to ensure the stability of their connection.

[0035] After the plug and the connector 8 are engaged, the position of the plug is locked by the latch 4. The latch 4 is set on the carrier plate 1, protruding from the surface of the carrier plate 1 and protruding into the connector 8 to lock the plug by engaging the pre-set slot on the plug. In order to facilitate disassembly, the latch 4 has a protrusion 7 on the side away from the connector 8. The protrusion 7 can serve as an operating structure. When an external force is applied to the protrusion 7, the latch 4 is moved, so that the latch 4 can engage the slot on the plug or disengage from the slot, thereby releasing the constraint on the plug and allowing the plug to be pulled out from the connector 8.

[0036] In this embodiment, the buckle 4 protrudes into the insertion part 8 on one side and serves as a stop block 13. The protrusion 7 can be driven by external force to elastically deform the buckle 4 so that the stop block 13 is in the insertion part 8 or withdrawn from the insertion part 8.

[0037] like Figure 2As shown, the carrier plate 1 is provided with a sliding hole 3, and the sliding hole 3 and the buckle 4 on the carrier plate 1 are arranged at intervals. The sliding hole 3 extends axially to form a loop frame 5 protruding from the surface of the carrier plate 1. The inside of the loop frame 5 is connected to the sliding hole 3. The side plate 2 that can be slidably adjusted is connected to the slider 15. The slider 15 slides and adjusts its position in the sliding hole 3.

[0038] The loop frame 5 extends the axial length of the sliding hole 3, improving its sliding stability; a set of opposite sides of the loop frame 5 are respectively opened with sliding grooves 6, forming two parallel sliding grooves 6, which penetrate the side wall of the loop frame 5; the slider 15 is connected to a sliding rod 9, one end of the sliding rod 9 is engaged with one of the sliding grooves 6, and the other end is engaged with the other sliding groove 6. When the slider 15 moves along the sliding hole 3, the sliding rod 9 moves synchronously along the sliding groove 6.

[0039] The side plate 2 is connected to the slide rod 9 via the slider 15. The two ends of the slide rod 9 are respectively engaged with the slide groove 6 for actual sliding positioning, which improves its stability. The side plate 2 maintains its position to ensure stability when the plug is engaged, so that the side plate 2 has good engagement and positioning performance before and after adjusting its position.

[0040] Side plate 2 is subjected to external force to drive slider 15 and slide rod 9 to move, or slider 15 and slide rod 9 are subjected to external force to drive side plate 2 to move. The direction of movement of side plate 2 is perpendicular to the plane it is located in and parallel to the plane of carrier plate 1. The two side plates 2 are parallel to each other. Figure 1 As shown, the distance between the two side plates 2 can be changed by moving the side plate 2.

[0041] After adjusting the position of side plate 2, it is necessary to lock the position of side plate 2 so that when the plug is inserted into the connector 8, the plug can be engaged and the plug position can be locked. The locking structure is set between the slide rod 9 and the U-shaped frame 5, and the locking buckle 10 is connected to the slide rod 9. After the slide rod 9 moves to the desired position, the locking buckle 10 can cooperate with the slide rod 9 to lock the position, thereby locking the relative position of side plate 2 and carrier plate 1.

[0042] In this embodiment, both the sliding hole 3 and the sliding groove 6 are rectangular holes, the slider 15 is a cube, and the sliding rod 9 is a long rod with a rectangular cross-section. The slider 15 slides with the sliding hole 3, and the sliding rod 9 engages with the sliding groove 6. The sides of the engagement positions are in close contact, which can play a good guiding role and position constraint, and apply a stable limiting role to the plug.

[0043] like Figure 2 and Figure 3 As shown, the side plate 2 has an L-shaped cross section. One end of the side plate 2 faces the carrier plate 1, and the other end has a bent section. A space for accommodating the plug is formed between the two side plates 2. An opening is formed at the end of the space away from the carrier plate 1. The width of the opening is smaller than the width of the plug part 8, so that the side of the plug part 8 has an opening, which makes it easy for the plug part 8 to undergo elastic deformation to adapt to the plug.

[0044] The buckle 4 is located between the two side plates 2, and the protrusion 7 of the buckle 4 is located on the side opposite to the insertion part 8. The slide bar 9 and the slider 15 move relative to the sliding hole 3 to adjust the distance between the two side plates 2.

[0045] like Figure 3 As shown, the loop frame 5 protrudes from the surface of the carrier plate 1. The inner cross-section of the loop frame 5 is the same as the cross-section of the sliding hole 3. One end of the slider 15 is connected to the side plate 2, and the other end passes through the sliding hole 3 and connects to the sliding rod 9. In addition, one end of the slider 15 connected to the sliding rod 9 extends into the loop frame 5, extending the area of ​​the sliding fit on the side of the slider 15 and improving its stress stability.

[0046] The two ends of the slide rod 9 slide in conjunction with the slide groove 6, keeping the axis of the slide rod 9 perpendicular to the length direction of the slide groove 6, thus preventing the slide rod 9 from causing the side plate 2 to shift. The locking buckle 10 is connected to the slide rod 9 segment inside the loop frame 5. A spring 11 is provided between one side of the slide rod 9 and the loop frame 5. One end of the spring 11 acts on the loop frame 5, and the other end abuts against the slide rod 9 to maintain the position of the slide rod 9.

[0047] The inner walls of a set of opposite sides of the sliding groove 6 in the U-shaped frame 5 are provided with locking holes 14. The positions of the locking holes 14 correspond to the positions of the adapter plugs on the side plate 2. The locking buckle 10 cooperates with the locking holes 14 to lock.

[0048] One end of the locking buckle 10 is connected to the slide bar 9, and the other end engages with the locking hole 14 for locking. The locking buckle 10 engaging with the locking hole 14 can adopt a limiting rod, limiting block, or other structural form, which can be embedded in the locking hole 14 to lock the position. When unlocking, a tool can be used to pry the locking buckle 10, causing the limiting rod, limiting block, etc., to retract from the locking hole 14, making it easier for the slide bar 9 to adjust its position.

[0049] like Figure 3 As shown, the inner wall of the slide groove 6 is provided with a guide groove. The distribution direction of the guide groove is consistent with the sliding direction of the side plate 2 relative to the carrier plate 1. The part of the slide rod 9 located in the slide groove 6 is connected to the guide pin 12, and the guide pin 12 is slidably engaged with the guide groove.

[0050] Guide grooves are provided on a pair of side walls in the slide groove 6, and guide pins 12 are respectively fitted on them. The guide pins 12 fitted on the guide grooves in the same slide groove 6 are connected to the same end of the slide rod 9.

[0051] The slide groove 6 constrains the movement of the side plate 2 from both ends of the slide rod 9. The addition of guide grooves and guide pins 12 strengthens the connection between the slide rod 9 and the loop frame 5. The guide pin 12 can be an elastic retractable pin to facilitate retraction during installation, thereby improving the strength of the connection between the slide rod 9 and the loop frame 5 and thus improving the stability of the side plate 2 before and after movement.

[0052] Example 2

[0053] In another typical embodiment of the present invention, such as Figures 1-3 As shown, a wiring device is given.

[0054] The wiring device utilizes an adjustable and detachable terminal as in Embodiment 1. The adjustable and detachable terminal and the plug are respectively connected to the lead wire. The plug is inserted into the insertion part 8 and engaged and fixed with the buckle 4.

[0055] Two side plates 2 are respectively connected to the carrier plate 1. At least one side plate 2 can move relative to the carrier plate 1. The distance between the two side plates 2 can be adjusted to change the size of the formed plug part 8 and lock the position. It can adapt to plugs of different specifications without replacing the terminals, ensuring the firmness and reliability of the connection, realizing stable circuit operation, and meeting debugging requirements.

[0056] The buckle 4 has a protrusion 7, which is located on the side away from the plug part 8. When the plug is replaced and the spacing of the side plate 2 is adjusted to accommodate different plug specifications, the buckle 4 can be operated through the protrusion 7. The buckle 4 retracts from the stop block 13 inside the plug part 8, so that the plug can be smoothly removed from the plug part 8 to avoid damage to the lead wire connection position.

[0057] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
