Description

Technical Field

[0001] This utility model relates to terminal blocks widely used in industrial power transmission, shipbuilding, automotive and aviation industries, and more specifically, to a combination terminal block with adjustable wiring direction that allows for adjustment of the wiring direction of the terminal block relative to the fixed part such as the terminal post during installation, according to the installation environment. Background Technology

[0002] Currently, common terminal blocks, such as those used in aircraft, are... Figure 9 The terminal block shown is an integrated type and its angle cannot be adjusted.

[0003] However, during the 3D design and actual installation of the wiring harness, the spatial routing and actual laying path of the cables within the harness are extremely complex due to spatial constraints. Furthermore, it is impossible to pre-measure the installation angles between the terminals at both ends of the harness, leading to mismatches in the installation angles. This can result in the harness being unable to be installed or exhibiting significant residual stress after installation. Additionally, residual stress after installation may cause the terminals to deform easily during later use, thus affecting electrical performance. Moreover, during aircraft test flights and operations, it is frequently observed that terminals installed in confined spaces exhibit excessive deformation or even destructive cracks. However, repairs and replacements performed in such confined spaces are extremely inconvenient, thus complicating aircraft maintenance.

[0004] To address this, existing technologies have designed terminal blocks with protective functions, improved connection strength, or enhanced stability, such as Chinese utility model patents CN219226634U, CN218940033U, and CN218940083U. However, these terminal blocks are mainly suitable for special environments. For example, the terminal block CN219226634U is suitable for environments with high requirements for insulation and sealing, while the terminal blocks CN218940033U and CN218940083U are suitable for environments with special requirements for connection stability. However, considering the overall economic cost, these terminal block solutions are not universally applicable, and they do not solve the technical problem of angle adjustment.

[0005] In addition, the applicant previously designed an adjustable-angle combination terminal block (Chinese Invention Patent Announcement CN114221147B) to address the technical issue of angle adjustment. This mainly consists of a crimping sleeve and three replaceable tongues (termination tongues) at different angles (0°, 45°, and 90° in the vertical direction). During installation, by selecting a suitable bending angle for the termination tongue and adjusting the relative rotation angle between the termination tongue and the crimping sleeve (the circumferential position of the tongue base relative to the crimping sleeve), the termination tongue of the terminal block can be better adapted to the actual installation requirements, thus reducing residual stress on the wiring harness after installation to some extent. However, the tongue adjustment range of this solution is mainly limited to several specific angles in the vertical direction, making it only suitable for applications with ample operating space and not for confined planar spaces.

[0006] Therefore, there is an urgent need for a terminal block that is suitable for narrow installation spaces and can efficiently and conveniently adjust the wiring direction of the terminal block relative to the fixed part such as the terminal post during installation and maintenance using only a single type of termination tongue. Utility Model Content

[0007] This utility model is made to solve the above-mentioned problems in the prior art. Its purpose is to provide a combined terminal block that can adjust the wiring direction. During installation and maintenance, there is no need for trial and error installation. It can efficiently and conveniently adjust the wiring direction of the terminal block relative to the fixed part.

[0008] To achieve the above objectives, this utility model provides a combined terminal block with adjustable wiring direction, comprising: a crimping sleeve for crimping cables; and a termination tongue assembly adapted to connect to a fixed part, wherein the termination tongue assembly comprises: a first tongue portion connected to the crimping sleeve; and a second tongue portion having an N-sided tongue base and a termination tongue extending outward from any side of the N-sided structure of the tongue base. The second tongue portion is connected to the first tongue portion via a tongue fastening connector and is rotatable relative to the first tongue portion such that different sides of the tongue base abut against the first tongue portion. The termination tongue of the second tongue portion is connected to the fixed part via the termination fastening connector.

[0009] Based on the above-described configuration, compared to existing terminal blocks, the adjustable wiring direction combination terminal block of this invention eliminates the need to consider the relative angle between the terminal blocks at both ends of the cable when crimping the cable to the terminal block. It also eliminates the need to select a suitable configuration from different replaceable tongues (termination tongues) as required by existing technologies. Instead, by rotating the second tongue relative to the first tongue, different sides of the tongue base abut against the first tongue, the termination tongue can be adjusted to a more suitable orientation for installation. This eliminates the need for trial-and-error installation and allows for efficient and convenient adjustment of the wiring direction of the terminal block relative to the fixed part.

[0010] Furthermore, the connection terminals constructed as described above can reliably select an orientation that is more suitable for installation even in confined planar spaces, which can greatly reduce the residual stress on the cables in such installation spaces.

[0011] In addition, since the termination tongue assembly (first tongue part and second tongue part) adopts a separate design and is assembled, it is only necessary to disassemble or loosen the corresponding tongue fastener and adjust the angle of the second tongue part relative to the first tongue part. Only one type of termination tongue assembly can be used, without the need to change materials, thus reducing the pressure of inventory management.

[0012] Furthermore, compared to traditional integrated terminal blocks, no termination allowance is required for the cable length, saving on cable materials. Simultaneously, during wire harness manufacturing, the manufacturing cycle is shortened and manufacturing efficiency is improved because terminal angles do not need to be considered. Moreover, during subsequent maintenance, the relative angle between the termination tongue of the second tongue and the first tongue connected to the crimp sleeve can be flexibly adjusted as needed, resulting in high efficiency for cable connection installation and replacement.

[0013] Furthermore, the first tongue portion of the end-connecting tongue assembly has a connecting cylindrical portion connected to the crimping sleeve and a connecting tongue formed on the opposite side of the crimping sleeve of the connecting cylindrical portion. The connecting cylindrical portion and the connecting tongue of the first tongue portion are formed into a stepped structure with a stepped bottom surface and a stepped side surface.

[0014] Preferably, the base of the N-sided structure of the second tongue portion has a base back side and N-1 base side sides other than the side with the end tongue extending out, and the outer end face of the connecting cylindrical portion of the first tongue portion becomes a stepped bottom surface that can abut against the base side side of the base of the second tongue portion.

[0015] At the same time, or optionally, the connecting surface of the connecting tongue of the first tongue portion becomes a stepped side surface that can abut against the back surface of the base of the tongue base of the second tongue portion.

[0016] As described above, since the base side of the second tongue portion abuts against the outer end face (step bottom surface) of the connecting cylindrical portion of the first tongue portion in a surface-to-surface engagement manner, compared to the point-to-surface or line-to-surface engagement manner when an arc abuts against a surface, this surface-to-surface engagement...

[0017] The one-sided combination method can ensure adjustable angle while providing better anti-slip properties. Therefore, it can guarantee good electrical connection between the two and can ideally adapt to application scenarios with complex vibration environments and high requirements for the connection stability of the terminals.

[0018] Furthermore, a first tongue fastening hole is formed on the base of the tongue in the second tongue portion, and a second tongue fastening hole is formed on the connecting tongue in the first tongue portion.

[0019] Furthermore, the tongue fastening connector is a fastening screw with a fastening part and a tightening part.

[0020] A wave-shaped washer is fitted onto the tightening part of the tongue fastening connector, and the wave-shaped washer is located between the fastening part and the tongue base of the second tongue part.

[0021] As described above, the wave-shaped gasket not only prevents the tongue fastener from loosening relative to the tongue base, but also buffers the impact from the cable on the termination tongue assembly, thereby enhancing the reliability and stability of the tongue fastener.

[0022] In addition, before the tongue fastening connector passes through the second tongue fastening hole and the first tongue fastening hole and is tightened, the second tongue portion of the terminating tongue assembly can rotate relative to the first tongue portion. After the tongue fastening connector is tightened, the back side of the base of the tongue base of the second tongue portion abuts against the connecting surface of the connecting tongue of the first tongue portion.

[0023] In addition, the first tongue portion and the crimping sleeve can be connected to each other either by a sleeve fastening connector or by being connected as a whole.

[0024] As the base of the tongue in the N-gonal structure, a regular polygonal configuration can be considered.

[0025] Non-regular polygonal configurations can also be selected, including configurations composed of multiple regular polygons.

[0026] In addition, the end tongue of the second tongue portion can extend outward in a straight line from any side of the regular N-gon structure of the tongue base, or it can extend outward at a certain bending angle or curvature relative to any side of the regular N-gon structure of the tongue base.

[0058] The following, combined with Figures 1 to 4 The combined terminal block 100 of the first embodiment of the present invention will be described in detail below.

[0059] Figure 1 This is a schematic perspective view showing the overall structure of the combined terminal block 100 according to the first embodiment of this utility model. Figure 1 As shown, the combined terminal block 100 of the first embodiment of this utility model is a terminal block capable of adjusting the wiring direction. It includes: a crimping sleeve 110, which is used to crimp a cable 200 to achieve an electrical connection between the crimping sleeve 110 and the cable 200; and a termination tongue assembly 120, which is adapted to connect to a fixed part 400 such as a terminal block (see reference). Figure 8 The sleeve fastening connector (not shown), such as a fastening screw, is used to connect the end tongue assembly 120 to the crimping sleeve 110; and a flat washer (not shown) is used to prevent the sleeve fastening connector from loosening.

[0060] In this description of the utility model, for the sake of simplicity, the act of connecting the terminal block to a fixed part such as a terminal post, i.e., the connection of the terminal block, is simply referred to as termination. Furthermore, in the specification, "termination tongue" and "termination tongue assembly" refer to the tongue or tongue assembly that connects the terminal block to the fixed part such as a terminal post, and "termination fastening connector" and "termination fastening hole" refer to the fastening connector or fastening hole used to connect the terminal block to the fixed part such as a terminal post.

[0061] Figure 2 It means Figure 1 The exploded perspective view of the combined terminal block 100 shown is a schematic exploded perspective view of its structure. Figure 3 It means Figure 2 The exploded perspective view of the connection relationship between the first tongue portion 121 of the terminating tongue assembly 120 and the crimping sleeve 110 in the combined terminal block 100 shown here makes the connection relationship between the various components of the combined terminal block 100 clearer.

[0062] like Figure 2 As shown, the termination tongue assembly 120 includes: a first tongue portion 121, which is connected to a crimping sleeve 110 via a sleeve fastening connector (not shown); and a second tongue portion 122, which is connected to the first tongue portion 121 via a tongue fastening connector 130, and is connected to a fixed portion 400 such as a terminal block via a termination fastening connector 300.

[0063] like Figure 3 As shown, the crimping sleeve 110 has a cable crimping portion 111 for crimping the cable 200 and a connecting post portion 112 protruding from the cable crimping portion 111 toward the side opposite to the cable 200. The first tongue portion 121 of the termination tongue assembly 120 has a connecting cylindrical portion 121a that accommodates the connecting post portion 112 when connected to the crimping sleeve 110, and a connecting tongue 121b formed on the side opposite to the crimping sleeve 110 of the connecting cylindrical portion 121a. The connecting cylindrical portion 121a and the connecting tongue 121b of the first tongue portion 121 are formed with a stepped structure having a stepped bottom surface 121a1 and a stepped side surface 121b1, for example... Figure 2 The L-shaped structure shown.

[0064] In addition, such as Figure 2As shown, the second tongue portion 122 of the termination tongue assembly 120 includes: a tongue base 122a, which has an N-sided structure. In this embodiment (first embodiment), the N-sided tongue base 122a is, for example, a regular pentagonal configuration; and a termination tongue 122b, which extends outward from any side (any side face) of the N-sided structure of the tongue base 122a. A termination fastening hole 122b1 is formed on the termination tongue 122b, and the termination fastening hole 122b1 provides a connection for the termination fastening connector 300 (see reference). Figure 8 The terminal tongue assembly 120 (more specifically, the second tongue portion 122 of the terminal tongue assembly 120) is passed through to secure it to the terminal block or the fixed portion 400.

[0065] Additionally, the N-sided structure of the second tongue portion 122 (e.g.) Figure 2 The pentagonal structure shown has a base 122a of base back 122a1 and N-1 (e.g., N-1) other than the side extending from which the end tongue 122b is attached. Figure 2 (As shown in the diagram) The four base side surfaces 122a2. The outer end face of the connecting cylindrical portion 121a of the first tongue portion 121 becomes a stepped bottom surface 121a1 that can abut against the base side surface 122a2 of the tongue base 122a of the second tongue portion 122. Alternatively, the connecting surface of the connecting tongue 121b of the first tongue portion 121 becomes a stepped side surface 121b1 that can abut against the base back surface 122a1 of the tongue base 122a of the second tongue portion 122.

[0066] In addition, a first tongue fastening hole 122a3 is formed on the tongue base 122a of the second tongue portion 122, and a second tongue fastening hole 121b2 is formed on the connecting tongue 121b (the stepped side surface 121b1 that serves as the connecting surface) of the first tongue portion 121.

[0067] Internal threads (not shown) are etched in the first tongue fastening hole 122a3 and the second tongue fastening hole 121b2. By rotating the tightening part 132 of the tongue fastening connector 130, the external thread (not shown) etched on the fastening part 131 engages with the internal threads etched in the first tongue fastening hole 122a3 and the second tongue fastening hole 121b2, thereby fixing the first tongue part 121 and the second tongue part 122 of the end tongue assembly 120 together. Furthermore, preferably, a wave-shaped washer 140 is fitted onto the tightening part 132 of the tongue fastening connector 130, for example, between the fastening part 131 of the tongue fastening connector 130 and the tongue base 122a of the second tongue part 122. The wave-shaped gasket 140 not only prevents the tongue fastening connector 130 from loosening relative to the tongue base 122a, but also buffers the impact from the cable 200 on the termination tongue assembly 120, thereby enhancing the reliability and stability of the tongue fastening connector 130.

[0068] Before the tongue fastening connector 130 is tightened, the first tongue portion 121 and the second tongue portion 122 of the terminating tongue assembly 120 are pre-fixed. At this time, the second tongue portion 122 can rotate relative to the first tongue portion 121. That is, the tongue base 122a of the second tongue portion 122 rotates from abutting against the step bottom surface 121a1 of the first tongue portion 121 on one base side 122a2 to abutting against the step bottom surface 121a1 of the first tongue portion 121 on the other base side 122a2. This changes the orientation of the terminating tongue 122b of the second tongue portion 122, which will be connected to the terminal block or other fixed part 400 by the terminating fastening connector 300, to a more suitable orientation for installation. This minimizes the residual stress on the cable 200 connected to the terminal block or other fixed part 400 by the connecting terminal 100. After adjusting the angle of the second tongue portion 122 relative to the first tongue portion 121 of the end tongue assembly 120, tighten the tongue fastening connector 130. At this time, the back side 122a1 of the base portion 122a of the second tongue portion 122 abuts against the connecting surface (step side 121b1) of the connecting tongue 121b of the first tongue portion 121, thereby locking and fixing the end tongue assembly 120.

[0069] Figure 4 It means Figure 1 In the combined terminal block 100 shown, the second tongue portion 122

[0070] This is a schematic diagram showing how the relative position (relative angle) of the end tongue 122b of the second tongue portion 122 (which is connected to the terminal block or the like) relative to the crimp sleeve 110 connected to the cable 200 changes when the tongue base 122a rotates at different angles relative to the first tongue portion 121 (the stepped bottom surface 121a1).

[0071] When the base 122a of the second tongue portion 122 is a regular N-gon configuration.

[0072] The relative position (relative angle) of the end tongue 122b of the second tongue portion 122 relative to the crimp sleeve 110 connected to the cable 200 can be adjusted to 360° / N, 2*360° / N, 3*360° / N, ..., (n-1)*360° / N, that is, the tongue base 122a is as follows: Figure 4 In the case of the regular pentagonal configuration shown, the relative angle between the end tongue 122b and the crimp sleeve 110 can be adjusted to 72°, 144°, 216°, and 288°. Furthermore, the polygonal structure of the tongue base 122a is not limited to... Figure 4 The regular pentagonal configuration shown can also be Figure 5 In the hexagonal configuration shown (second embodiment), the relative angle between the end tongue 122b and the pressing sleeve 110 can be adjusted to 60°, 120°, 180°, 240°, or 300°. Furthermore, the polygonal structure of the tongue base 122a can also be an equilateral triangle, square, or a regular heptagon or larger polygon; however, considering the ease of processing the tongue base 122a and the adaptability of angle adjustment, a polygon with a hexagonal shape is preferred. Figures 1 to 4 The regular pentagon shown and Figure 5 The regular hexagon shown.

[0073] Next, refer to Figures 6 to 8 The assembly method is described in detail for assembling and fixing the combined terminal block 100 of this utility model with the cable 200 and the fixing part 400.

[0074] like Figure 6 As shown, firstly, using a wiring tool (not shown), one end of the cable 200 is crimped into the cable crimping portion 111 of the crimping sleeve 110 of the combined terminal block 100 of this invention. Then, as... Figure 3 The first tongue portion 121 of the end tongue assembly 120 is connected to the crimping sleeve 110 by a sleeve fastening connector (not shown).

[0075] Next, as Figure 7As shown, the base side 122a2 of the tongue base 122a of the second tongue portion 122 of the terminating tongue assembly 120 is abutted against the outer end face of the connecting cylindrical portion 121a of the first tongue portion 121, aligning the first tongue fastening hole 122a3 and the second tongue fastening hole 121b2, and the first tongue portion 121 and the second tongue portion 122 of the terminating tongue assembly 120 are pre-fixed by the tongue fastening connector 130 (e.g., through the wave-shaped gasket 140). At this time, the rotation angle of the second tongue portion 122 relative to the first tongue portion 121 is adjusted according to the position of the cable 200 pressed into the crimp sleeve 110 and the fixed portion 400 such as the terminal block in the fixed position. More specifically, as Figure 7 As shown, the tongue base 122a of the second tongue portion 122 abuts against the step bottom surface 121a1 of the first tongue portion 121 from one of its base sides 122a2. Figure 7 The relative position of the left half) rotates to another base side 122a2 and abuts against the step bottom surface 121a1 of the first tongue portion 121. Figure 7 (relative positional relationship of the right half) to change the orientation of the end tongue 122b of the second tongue portion 122, which will be connected to the terminal block or the fixed portion 400 via the end fastening connector 300, to a more suitable orientation for installation.

[0076] After adjusting the angle of the second tongue portion 122 relative to the first tongue portion 121 of the end tongue assembly 120, the tongue fastening connector 130 is tightened so that the base back side 122a1 of the tongue base portion 122a of the second tongue portion 122 abuts against the connecting surface (step side side 121b1) of the connecting tongue 121b of the first tongue portion 121, thereby locking and fixing the end tongue assembly 120.

[0077] Finally, as Figure 8 As shown, the termination fastening connector 300 is passed through the termination fastening hole 122b1 formed on the termination tongue 122b and tightened to fasten the terminal 100 (more specifically, the second tongue portion 122 of the termination tongue assembly 120) to the fixed portion 400 such as the terminal post.

[0078] Since the angle of the cable 200 relative to the fixed part 400 such as the terminal block is pre-adjusted to a more suitable angle for installation by the rotation of the second tongue part 122 of the termination tongue assembly 120 relative to the first tongue part 121, the residual stress on the cable 200 connected to the fixed part 400 such as the terminal block and the connector 100 can be minimized.

[0079] While the embodiments of this utility model have been described in detail above, those skilled in the art should understand that these are merely illustrative examples, and the utility model is not limited to the specific details and representative embodiments shown and described herein. Those skilled in the art can make various suitable changes or modifications to these embodiments without departing from the scope of protection of the claims of this utility model, but all such changes and modifications fall within the protection scope of this utility model.

[0080] For example, in this invention, the sleeve fastening connector and the tongue fastening connector 130 are described as fastening screws, but this invention is not limited to this and other types of fasteners may also be used. Furthermore, in the above description, the structure in which the first tongue portion 121 and the crimping sleeve 110 are connected to each other via the sleeve fastening connector is described as an example, but this invention is not limited to this. From a cost-saving perspective, the first tongue portion and the crimping sleeve may also be integrally formed.

[0081] Furthermore, the flat washer and wave-shaped washer 140 described above can also be other types of washers or gaskets, such as wave spring washers, as long as they can perform the corresponding function, and are not limited to the examples described above. In addition, the flat washer and wave-shaped washer 140 are not essential components, and can be selected and used according to actual needs.

[0082] Furthermore, in the combined terminal block 100 of this utility model, the terminating tongue 122b of the second tongue portion 122, which is connected to the fixed portion 400 such as the terminal post, can extend outward in a straight line relative to the tongue base 122a connected to the first tongue portion 121, either as shown in the figure, from any side (any one side) of the regular N-gon structure of the tongue base 122a, or it can extend outward at a certain bending angle α° or curvature relative to any side (any one side). When it extends outward at a certain bending angle α° instead of in a straight line, the relative position (relative angle) of the terminating tongue 122b of the second tongue portion 122 relative to the crimping sleeve 110 connected to the cable 200 can be adjusted to 360° / N.

[0083] ±α°, 2*360° / N±α°, 3*360° / N±α°,…, (n-1)*360° / N

[0084] ±α°.

[0085] Furthermore, the tongue base 122a of the second tongue portion 122 is not limited to a regular N-gon configuration. As long as it is suitable for processing and for reducing residual stress on the connected cable 200, it can also be a non-regular N-gon configuration, including configurations composed of combinations of various types of regular N-gons. For example, a combination of a regular hexagon and a regular dodecagon can be used. Thus, the relative position (relative angle) of the termination tongue 122b relative to the crimping sleeve 110 can be adjusted, for example, to 60° (360° / 6), 120° (4*360° / 12, i.e., 2*360° / 6), 150°, etc.

[0086] ° (5*360° / 12), 180° (6*360° / 12, i.e., 3*360° / 6), 210°

[0087] Structures of (7*360° / 12), 240° (8*360° / 12, i.e., 4*360° / 12), and 300° (5*360° / 6).
