Technical Field

[0001] The utility model relates to the technical field of terminal devices, in particular to a wiring terminal. Background Art

[0002] Existing terminal blocks often use screw fastening, where screws, washers, and nuts work together to lock the wire or ferrule inside the terminal housing, completing the wiring. During use, a tool (such as a screwdriver) is required to first loosen the screw until it is completely disengaged from the nut, and then insert the end of the cable for wiring. Without any other restraining mechanism between the screw and the housing, the screw can easily fall into or out of the housing, making subsequent operations inconvenient and affecting wiring efficiency. This requires improvement. Utility Model Content

[0003] To solve at least one of the above technical deficiencies, the present invention provides the following technical solutions:

[0004] The present application document discloses a terminal block, comprising a shell, a fastener, and a conductor, wherein a wiring hole and an operating hole connected to the cavity are provided on the peripheral wall of the shell, the conductor is at least partially located in the shell and has an electrical connector that is docked with an external cable, the fastener is at least partially located in the shell and corresponds to the operating hole, a connecting hole that is docked with the fastener is provided on the conductor, and further comprises a moving part and an elastic part, the moving part has a ring mouth and is sleeved on the conductor part in the shell through the ring mouth, the wiring hole corresponds to the ring mouth of the moving part, the fastener is connected to the moving part part above the connecting hole, an active cavity is provided below the connecting hole for the moving part to move downward, an elastic part is provided in the active cavity and the elastic part is connected to the moving part part below the conductor to reset the moving part, when external force drives the fastener to move downward and dock with the connecting hole on the conductor, the moving part that moves downward synchronously with the fastener cooperates with the conductor to perform a clamping action, and the downward movement of the moving part causes the elastic part to deform.

[0005] During use, the fastener is pressed down to the connecting hole on the conductor through the operating hole, and the fastener is docked with the connecting hole to be fixed. The moving part that moves down synchronously with the moving part cooperates with the conductor to clamp the cable connector in the middle. During the downward movement of the moving part, the moving part in the active cavity causes the elastic part to deform. After the external force drives the fastener to disengage from the connecting hole, the elastic part recovers and synchronously resets the moving part. Under the sleeve structure, the conductor limits the travel of the moving part, thereby preventing the fastener from falling out of the shell, making operation more convenient.

[0006] For the ring opening of the moving part, it can be a full ring or a semi-ring, and the specific shape can be a circular ring opening, a rectangular ring opening, etc.

[0007] For the operation hole, it refers to the hole through which the external component can be inserted to operate the fastener.

[0008] The connection between the fastener and the movable part is determined according to the docking structure between the fastener and the connecting hole. If the fastener and the connecting hole are interlocked or fixed in a snap-fit ​​manner, the fastener can be directly fixed on the movable part; when the fastener needs to be rotated to dock with the connecting hole, the fastener is pivotally connected to the movable part.

[0009] As for the positions of the elastic part and the moving part, if the elastic part is between the moving part and the conductor above in the active cavity, or the elastic part is in the active cavity below the moving part, preferably, the elastic part is below the moving part and the end of the elastic part abuts against the bottom surface of the moving part. When the external force drives the moving part to move downward, the elastic part is compressed by the moving part. After the external force is removed, the elastic part recovers and resets the moving part. This structure is convenient for assembly and has high operational stability.

[0010] Furthermore, both sides of the moving member are slidably connected to guide grooves formed at the sides of the corresponding conductors, and the movement of the moving member is guided by the guide grooves, thereby improving the stability of operation.

[0011] As for the specific shape of the moving part, it can be selected according to needs, as long as it has a ring mouth and meets the use requirements. Preferably, the moving part is in the shape of a ring, which helps to simplify the structure and facilitates molding and assembly.

[0012] Furthermore, the movable part is bent and has mounting holes at opposite ends. The fastener is connected to the mounting holes, which are arranged at opposite ends. When the fastener is installed, the ends are movable to facilitate assembly.

[0013] Furthermore, sockets are formed at relative positions in the shell cavity and a movable cavity is set between the two sockets. The two ends of the conductor are fixed at the corresponding sockets and one end of the conductor extends from the socket to the outside to form an electrical connector. A connecting hole is set on the part between the two ends of the conductor. The positions of the sockets and the movable cavity are reasonably arranged to facilitate the installation of the conductor and the movable parts.

[0014] Furthermore, the top surface of the shell is open, and the opening is used as an operating hole. A wiring hole is formed on the front surface of the shell. Using the opening as the operating hole helps save materials and reduce costs.

[0015] Furthermore, the connecting hole is a threaded hole, the fastener is threadedly engaged with the connecting hole, and the fastener is pivotally connected to the moving part. Fasteners such as common bolts, screws, etc. are easy to purchase and replace, and the docking and disengagement of the fastener and the connecting hole are easier to operate.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] Example 1

[0026] In this example, a terminal block includes a housing 1, a fastener 4, and a conductor 2. The housing 1 is formed with a wiring hole 101 and an operating hole 100 connected to the cavity. The main body of the conductor 2 is located in the housing 1 and the conductor 2 has an electrical connector 21 for connecting to an external cable. The conductor 2 is formed with a connection hole 22 that connects to the fastener 4. The fastener 4 corresponds to the connection hole 22. Figure 1 、 Figure 2 As shown above the connection hole 22, the fastener 4 is at least partially located in the housing 1. Figure 2In the illustrated state, the fastener 4 is disengaged from the connection hole 22, ready for cable insertion. In this state, if the head end of the fastener 4 passes over or is adjacent to the operating hole, the end of the cable can be inserted through the wiring hole during use. A screwdriver or the like can then be inserted through the operating hole to disengage the fastener and mate it with the connection hole, allowing another cable to mate with the electrical connector. Regarding the operating and wiring holes, the top surface of the housing 1 can be directly open, with this opening serving as the operating hole 100, or a through-hole of appropriate diameter can be formed on the top surface of the housing, with this through-hole serving as the operating hole, and a wiring hole 101 can be formed on the front surface of the housing. The above components are conventional in composition and coordination, and will not be further described.

[0027] In this example, in order to prevent the fastener from being separated from the housing, a moving part 3 and an elastic part 5 are added. Figure 1 、 Figure 2 、 Figure 3 Shown in Figure 1, moving part 3 itself is rectangular annular shape, and moving part 3 is enclosed on the electric conductor 2 main parts in the housing 1 by annular opening 31, and housing 1 place wiring hole 101 is relative with annular opening 31, and the cable end that is convenient to stretch into from the wiring hole stretches into annular opening. Fastener 4 is in moving part 3 annular parts place above connecting hole 22, and when fastener moves down, moving part moves down synchronously, and after fastener and connecting hole are completed docking, the moving part annular part on fastener periphery cooperates with the electric conductor below to clamp and fix the cable termination that stretches into annular opening from the wiring hole.In this example, show as example with the annular opening of moving part with whole ring, certainly also can select semi-annular annular opening according to demand, be semi-annular as moving part.

[0028] In order to reset the moving part and meet the moving part movement requirements, in this example, an active cavity 103 is pre-formed at the housing 1 below the connection hole 22, so that the active cavity provides sufficient space to meet the moving part's downward movement requirements. An elastic member 5 is installed in the active cavity 103 and the elastic member 5 is connected to the ring portion of the moving part 3 below the conductor 2. For example, the elastic member is between the corresponding ring portion of the moving part and the upper conductor, or as Figure 2 、 Figure 3 The elastic member 5 is shown between the corresponding ring portion of the moving member 3 and the wall of the lower active chamber 103. The elastic member 5 is a common spring. The bottom end of the elastic member 5 abuts the bottom wall of the active chamber 103 and the head end abuts the bottom surface of the corresponding ring portion of the moving member 3 in the active chamber 103. When in use, if a screwdriver is inserted from the operating hole and abuts the fastener to move it downward, the moving member will be compressed as the fastener moves downward. When the screwdriver is removed, the deformation recovery force of the elastic member causes the moving member to move upward and reset. Of course, the bottom end of the elastic member can also be connected to the side wall of the active chamber, which can be selected according to needs.

[0029] In order to improve the moving stability of the moving parts, such as Figure 3As shown, in this example, guide grooves are formed along the longitudinal direction on both sides of the conductor 2 at the ring opening 31. The corresponding ring body portions on both sides of the moving member 3 pass through the guide grooves 23 and are loosely fitted to form a sliding connection. The guide grooves guide the movement of the moving member 3 when it moves up and down in the longitudinal direction. Of course, the moving member can also be guided by the size of the housing cavity wall, such as by loosely fitting the two sides of the moving member with the adjacent cavity walls.

[0030] For the connection between fasteners and moving parts, such as Figure 1 、 Figure 2 As shown, in this example, the connection hole 22 at the conductor 2 is a threaded hole, and the corresponding fastener 4 is a bolt. The fastener needs to be pivotally connected to the moving part. In order to facilitate the installation of the fastener, the moving part 3 in this example is bent, such as the two ends of the bar body are bent toward each other to form a ring shape, that is, the moving part, and grooves are formed at the end faces of the opposite ends. The two grooves form a mounting hole, and the fastener 4 is connected to the mounting hole. When the fastener is installed, the two ends are moved back to back to expand the mounting hole. In this example, the fastener needs to be pivotally connected, and can be used according to needs. Figure 2 In the illustrated structure, a circumferential annular groove 41 is formed along the peripheral wall of the fastener 4. The mounting hole is smaller than the outer diameter of the annular groove. When the fastener is pressed into the mounting hole, the hole wall of the mounting hole extends into the annular groove. The downward movement of the fastener simultaneously causes the movable member to move downward. At the same time, the fastener can rotate relative to the mounting hole to facilitate threaded connection with the connecting hole. Of course, other pivot connection structures can also be selected according to needs.

[0031] In addition, when the fastener and the connecting hole are connected by means of interlocking, snapping, etc., the fastener can also be directly fixed on the moving part.

[0032] To facilitate the installation of conductors and moving parts, such as Figure 2 As shown, in this example, a socket 102 is formed longitudinally at relative positions in the cavity of the shell 1 and a movable cavity 103 is formed between the two sockets. The two ends of the conductor 2 are inserted into the corresponding sockets 102 and fixed. One end of the conductor 2 extends from the socket to the outside to form an electrical connector 21, and a connecting hole 22 is formed on the part between the two ends of the conductor 2.

[0033] As for the materials of the housing and the moving part, the housing may be formed by plastic injection molding, and the moving part may be formed by metal material.

[0034] The above are only preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
