Description
TECHNICAL FIELD
[0001] The utility model relates to a wiring device technical field, specifically relates to a wiring element. BACKGROUND
[0002] The wiring terminal is a common wiring mechanism, and is commonly provided with a conductor, a screw, a connecting hole formed in the middle of the conductor and connected with the screw, and a foot in the conductor for electrically connecting with a PCB, etc. Other wires are fixed by the screw and the connecting hole. When the screw is completely separated from the connecting hole, the screw and the connecting hole are not connected by other mechanisms. The screw is easy to lose, and the subsequent wiring is inconvenient. Therefore, it needs to be improved. SUMMARY
[0003] To solve the above at least one technical defect, the utility model provides the following technical scheme:
[0004] The utility model discloses a wiring element, including conductor and fastener, the conductor has the foot for being electrically connected with external mechanism and the connecting hole for being connected with fastener, still include fixed bolster, the fixed bolster has ring mouth, the part in the conductor is in ring mouth to limit fixed bolster and move up and separate from the conductor, and the part of fixed bolster is set up at the top of the hole for fastener to extend into, the conductor and fixed bolster are slidably connected in the longitudinal direction, the fastener is provided with the baffle and the baffle is in the ring mouth of the fixed bolster below the hole, when the fastener moves up, the baffle abuts the ring mouth cavity wall at the periphery of the hole to limit the fastener to move up.
[0005] When using, the ring mouth cavity wall at the periphery of the hole abuts the baffle to limit the fastener to move up. In this configuration, the fastener cannot move up and separate from the fixed bolster. This reduces the phenomenon of the fastener separating and then being lost during wiring, making subsequent wiring more convenient.
[0006] Further, the baffle and the fastener are fixed, such as integrally formed, threaded connection, welding fixation, embedded fixation, etc.
[0007] Further, the baffle and the fastener are rotatably connected, such as common pivot connection. The fastener and the baffle can rotate relative to each other.
[0008] For the connection of the fastener and the connecting hole, preferably: the fastener and the connecting hole are threaded, which facilitates connection and unlocking. Of course, other connection structures, such as buckles, can also be used according to requirements.
[0009] Further, the conductor includes a foot, a transverse portion connected to the foot, and a longitudinal portion. The transverse portion extends into the ring mouth of the fixed bolster, and the connecting hole is provided on the transverse portion. The foot is provided at the bottom end of the longitudinal portion. In this configuration, the conductor is convenient for connecting with external mechanisms through the foot and connecting with the fixed bolster.
[0010] Further, the fixing support is annular, which simplifies the structure and facilitates molding.
[0011] Further, the fixing support is provided with a protrusion. When the fixing support moves upward relative to the conductor, the bottom surface of the transverse part of the conductor abuts against the top surface of the protrusion. During the continuous upward movement of the fixing support, the protrusion is deformed or the fixing support connected with the protrusion is deformed so that the protrusion can pass over the transverse part. After the protrusion is reset, the transverse part is located in the path of the downward movement. Without external force, the transverse part limits the downward movement of the protrusion, so that the fixing support is suspended relative to the conductor. The fixing support or the protrusion is made of elastic material.
[0012] Further, the fixing support and the conductor form a concave-convex cooperation at a predetermined position during the longitudinal movement of the fixing support relative to the conductor. The concave-convex cooperation longitudinally limits the fixing support so that it is kept at the position relative to the conductor. In this scheme, the fixing support is kept at the desired position relative to the conductor through the concave-convex cooperation, which facilitates subsequent wiring. For the concave-convex cooperation, the convex end is inserted into or separated from the corresponding concave end. The convex end is like a common protrusion, and the concave end is like a common slot, such as a clamping slot matched with the protrusion.
[0013] For the positions of the convex end and the concave end, the convex end is on the fixing support, and the corresponding concave end is on the conductor. Of course, the convex end can also be on the conductor, and the corresponding concave end can be on the fixing support. The selection is based on the demand. The fixing support or the convex end can be made of elastic material to better meet the concave-convex cooperation.
[0014] Further, the fixing support is provided with a protrusion, and the conductor is provided with a clamping slot matched with the protrusion. During the longitudinal movement of the fixing support relative to the conductor, the protrusion is inserted into the clamping slot to limit the longitudinal movement of the fixing support. The protrusion is the convex end, and the clamping slot is the concave end. The inclined surfaces at both ends of the protrusion facilitate the butt joint with the clamping slot.
[0015] Further, the fixing support is provided with a protrusion at the side wall of the annular opening, and the conductor is provided with a clamping slot at the longitudinal part. This layout facilitates the formation of the concave-convex cooperation and facilitates the assembly and molding.
[0016] Further, both ends of the protrusion are inclined in the longitudinal direction. The inclined surfaces can better guide the transverse part to press against the protrusion, and then deform the protrusion or the fixing support connected with the protrusion.
[0017] Further, at least two clamping slots are longitudinally spaced apart at the longitudinal part of the conductor, when the protrusion is clamped into the lower clamping slot, the height of the ring mouth above the transverse part of the conductor satisfies: when the stop sheet abuts against the cavity wall around the through hole, the tail end of the fastener is in the connecting hole; when the protrusion is clamped into the upper clamping slot, the height of the ring mouth above the transverse part of the conductor satisfies: when the stop sheet abuts against the cavity wall around the through hole, the tail end of the fastener is separated from the connecting hole, the position of the preset clamping slot is fixed, when the protrusion is clamped into the clamping slot, the fixed support is suspended relative to the conductor, and the tail end of the fastener is in the separated or non-separated state in the connecting hole, so that the Y-shaped head, the O-shaped head or the ordinary hard wire and soft wire of the wiring material are conveniently connected.
[0018] Further, the limiting block is arranged at the position adjacent to the protrusion on the fixed support, in the process that the fixed support moves longitudinally relative to the conductor, the clamping slot passes through the gap between the protrusion and the limiting block, and the width of the gap is smaller than the thickness of the longitudinal part at the clamping slot, so that the relative movement of the fixed support and the conductor is better limited by the limiting block, and the stability of the suspension is improved.
[0019] Further, the waist hole is arranged at the position adjacent to the protrusion on the fixed support and longitudinally extends, so that the waist hole is arranged to reduce the connection between the part connected with the protrusion and other parts, and the waist hole is better deformed to form the cooperation between the protrusion and the clamping slot.

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0033] Example 1
[0034] like Figure 1 , Figure 2 As shown, in this example, a wiring element includes a conductor 1, a fastener 3, and a fixing bracket 2. The conductor 1 has a leg 12 for electrical connection to an external mechanism and a connection hole 13 for mating with the fastener 3. The conductor, as shown... Figure 1 The configuration shown includes a leg 12 and connected horizontal and vertical portions 10 and 11. The vertical portion 11 extends longitudinally, and the horizontal portion 10 extends laterally. The end of the vertical portion 11 is connected to the end of the horizontal portion 10, as if integrally formed. The leg 12 is located at the bottom end of the vertical portion 11, as if integrally formed. In use, the leg 12 is inserted into the corresponding hole on the PCB board to form an electrical connection. Of course, other conductor configurations can be selected according to requirements.
[0035] Fixed bracket 2, as shown Figure 1 The ring-shaped structure shown has a cavity in the middle, which is called the annular opening 21. A portion of conductor 1 is located within the annular opening 21, as shown... Figure 1 , Figure 3 As shown, the transverse portion 10 of conductor 1 is located within the annular opening 21 of the fixed bracket 2, forming a nested structure. The longitudinal portion 11 extends from the openings at both ends of the fixed bracket 2, or it can extend from a hole formed in the side wall of the annular opening. Conductor 1 and fixed bracket 2 can slide relative to each other in the longitudinal direction. During the upward movement of fixed bracket 2, the lower annular portion of fixed bracket 2 abuts against the transverse portion 10, thereby restricting the further upward movement of fixed bracket and preventing it from detaching from conductor.
[0036] A connecting hole 13 is formed on the transverse portion 10 within the ring opening 21, and a through hole 22 is formed on the ring body of the fixing support 2 above the transverse portion 10 within the ring opening 21, and the through hole 22 corresponds to the connecting hole 13 in the longitudinal direction. The through hole 22 is used for the fastener 3 to extend into, as shown in Figure 1 、 Figure 2 、 Figure 3 The fastener 3 is selected as a bolt, and the diameter of the through hole 22 at least satisfies the bolt end to extend into, for example, the diameter of the through hole satisfies the bolt rod to extend into but cannot make the bolt head to pass through, of course, the diameter of the through hole can also satisfy the bolt to pass through entirely to enter the ring opening. The connecting hole 13 is a threaded hole, and the fastener 3 is threadedly connected with the connecting hole 13. Of course, the fastener can also be selected to be other ways to be connected with the connecting hole, such as buckling, fitting, etc.
[0037] In this example, a stop sheet 4 is added on the fastener 3, as shown in Figure 1 、 Figure 2 、 Figure 3 The stop sheet 4 is located within the ring opening 21 below the through hole 22 of the fixing support 2. The size of the stop sheet needs to satisfy the following requirements: when the fastener 3 moves upward, the stop sheet 4 abuts against the ring opening cavity wall at the through hole periphery to limit the fastener 3 to move upward. Specifically, as shown in Figure 1 The stop sheet 4 is a rectangular flat plate, and its width, length or diagonal length needs to be greater than the diameter of the through hole, so that under this configuration, when the stop sheet moves upward to the through hole, the side of the stop sheet 4 is outside the through hole to abut against the ring opening cavity wall at the through hole periphery. Of course, the stop sheet can also be a disc, and the diameter of the stop sheet is greater than the diameter of the through hole, or the stop sheet is other configuration, and the maximum distance between the two points in the transverse direction is greater than the diameter of the through hole.
[0038] For the connection of the stop sheet and the fastener, such as a fixed type, for example, the stop sheet 4 is integrally formed on the fastener 3, or the stop sheet is welded or threadedly connected and fixed on the fastener. Of course, the stop sheet can also be selected to be rotationally connected with the fastener, for example, the stop sheet is sleeved on the thinner part of the fastener through the intermediate formed hole, and the stop sheet can be horizontally rotated relative to the fastener, and the thicker part of the fastener above and below the stop sheet can axially limit the stop sheet to avoid it to be separated.
[0039] In use, as shown in the initial state in Figure 2 , the fastener 3 needs to be screwed upward, and the fixing support 2 is synchronously moved upward relative to the conductor 1 under the pushing of the stop sheet 4, when the fastener 3 moves to the required position, the wire end to be connected is extended into the ring opening and is located between the connecting hole and the stop sheet, then the fastener can be screwed downward, and the stop sheet cooperates with the conductor to clamp the wire end in the middle.
[0040] The longitudinal size of the ring opening to be extracted can be determined, for example, the fixing support 2 can be moved upward to the tail end of the fastener 3 to be located in the connecting hole or to be separated from the connecting hole, which is convenient to connect the end of the conventional wire or the end of the Y-shaped or O-shaped wire according to the application requirements.
[0041] For the convenience of wiring, a protrusion 23 is added to the fixed support 2 in this example, as shown in Figure 1 , Figure 3 The protrusion 23 is located at the side cavity wall of the ring mouth 21, and is in the path of the longitudinal movement of the transverse part 10 in the conductor 1. When the fixed support 2 moves upward relative to the conductor 1, the protrusion 23 abuts the bottom surface of the transverse part 10, and after being extruded, the side cavity wall of the ring mouth 21 connected to the protrusion 23 deforms outward, the protrusion retracts to avoid space, and the fixed support continues to move upward until the protrusion passes over the transverse part. When the fixed support moves downward relative to the conductor, the transverse part 10 is in the path of the downward movement of the protrusion 23. Without external force, the fixed support 2 can hover at this position relative to the conductor 1. The protrusion and the transverse part cooperate to make the fixed support hover relative to the conductor, which is convenient for subsequent wiring. Preferably, the two ends of the protrusion are beveled, and the transverse part abuts the bevel to better extrude the protrusion.
[0042] Of course, the position of the protrusion can also be predetermined, such as when the protrusion 23 passes over the transverse part 10, the tail end of the fastener 3 is in the connection hole 13 or is separated from the connection hole. In this way, the end of the conventional wire or the end of the Y-shaped or O-shaped wire can be connected according to the needs.
[0043] Because the retraction and reset of the protrusion require the fixed support to have a certain elasticity, the fixed support can be made of a material with elasticity such as copper. Of course, other materials with elasticity can also be selected to form the fixed support.
[0044] In addition, the protrusion can also be made of a material with elasticity, such as rubber. When the protrusion abuts the transverse part, the protrusion can deform to complete the avoidance of the transverse part. After passing over the transverse part, the protrusion returns to its original shape. This type of protrusion can also cooperate with the transverse part to make the fixed support hover relative to the conductor.
[0045] Embodiment 2
[0046] As shown in Figure 4 , Figure 5 , Figure 6 Compared with Embodiment 1, the difference is that in this example, the longitudinal part 11 of the conductor 1 in the wiring element protrudes from the hole formed in the ring mouth side wall of the fixed support 2. Of course, the hole can also be formed at both ends.
[0047] The second difference is that in this example, the fixed support 2 and the conductor 1 form a concave-convex cooperation at a predetermined position. Through the concave-convex cooperation, the fixed support is longitudinally limited to remain at this position relative to the conductor. One of the optional structures is as shown in Figure 4 , Figure 5 , Figure 6As shown, the protrusion 23 is formed on the side wall of the ring opening 21 in the fixing support 2, the fixing support 2 is formed of elastic material, and the protrusion 23 is in the path of the longitudinal movement of the transverse portion 10. The clamping groove 14 is formed on the side of the longitudinal portion 11 of the conductor 1, and the clamping groove is formed by forming a notch on the side. The clamping groove can satisfy the insertion of the protrusion, and the protrusion and the clamping groove form a concave-convex cooperation. When the fixing support 2 moves upward relative to the conductor, the longitudinal portion 11 of the conductor extrudes the protrusion 23 to deform the protrusion 23 connected to the fixing support, and the protrusion synchronously moves to avoid space. When the protrusion corresponds to the clamping groove, the fixing support connected to the protrusion returns to the original position, and the protrusion 23 is inserted into the clamping groove 14. When there is no external force, the groove wall of the clamping groove limits the movement of the protrusion, and the fixing support 2 is synchronously suspended relative to the conductor 1, which is convenient for subsequent wiring.
[0048] Of course, a plurality of clamping grooves can be formed on the side of the longitudinal portion 11 of the conductor 1 along the longitudinal direction. When the protrusion is inserted into the corresponding clamping groove, the fixing support is suspended at different positions relative to the conductor. For example, two clamping grooves 14 are formed on the side of the longitudinal portion 11 along the longitudinal direction. When the protrusion 23 is inserted into the lower clamping groove 14, the height of the ring opening above the transverse portion 10 of the conductor 1 satisfies that the blocking piece abuts against the cavity wall around the through hole, and the tail end of the fastener 3 is still in the connecting hole 13. In this way, the Y-shaped wire connector can be conveniently connected.
[0049] When the protrusion 23 is inserted into the upper clamping groove 14, the height of the ring opening 21 above the transverse portion 10 of the conductor 1 satisfies that the blocking piece 4 abuts against the cavity wall around the through hole 22, and the tail end of the fastener 3 is separated from the connecting hole 13. In this way, the O-shaped wire connector or other wire connectors can be conveniently connected.
[0050] In order to facilitate the avoidance of the protrusion, in this example, the two ends of the protrusion 23 are inclined in the longitudinal direction. The transverse portion abuts against the inclined surface to better extrude the protrusion.
[0051] In addition, the waist hole 24 is formed on the fixing support 2 adjacent to the protrusion 23 and extends longitudinally. The waist hole is increased to reduce the connection between the part of the fixing support connected to the protrusion and other parts, and the part can be better deformed to cooperate with the clamping groove and the like. Of course, as shown, Figure 4 、 Figure 5 、 Figure 6 As shown, part of the longitudinal portion 11 of the conductor 1 can also extend from the waist hole 24.
[0052] The limiting block 15 can also be formed on the fixing support 2 adjacent to the protrusion 23. In the process of the longitudinal movement of the fixing support relative to the conductor, the clamping groove passes through the gap between the protrusion 23 and the limiting block 15, and the width of the gap is smaller than the thickness of the longitudinal portion. The limiting block is increased to better limit the relative movement of the fixing support and the conductor, and the stability of the suspension is improved.
[0053] Of course, the protrusion can also be directly selected to be formed of elastic material, and then the protrusion is fixed with the fixing support, when the lateral part extrudes the protrusion, the protrusion can be deformed to avoid, and selection is made according to requirements.
[0054] The preferred embodiments of the present application are described above, the protection scope of the present application is not limited to the above-mentioned embodiments, and any technical solution belonging to the idea of the present application belongs to the protection scope of the present application. It should be pointed out that, for ordinary skilled in the art, some improvements and decorations without departing from the principle of the present application can also be considered as the protection scope of the present application.
