Description

Technical Field

[0001] This utility model relates to the field of electrical equipment, and in particular to a positioning bracket for crimping wire connectors. Background Technology

[0002] Wire connectors are critical components in electrical systems used to achieve reliable electrical connections and mechanical fixation between two or more wires. Their core function is to establish a low-resistance, highly stable conductive path while ensuring sufficient mechanical strength and environmental protection at the connection point. Physical contact between conductors is typically achieved through methods such as crimping, welding, screw fastening, or plugging. Insulating sleeves, heat-shrink tubing, or sealant are used for insulation and moisture-proofing / corrosion protection to prevent short circuits, oxidation, loosening leading to poor contact, overheating, or even fire risks. Widely used in power transmission, circuit board wiring, internal equipment wiring, and cable termination, they are fundamental components ensuring the safe operation of electrical systems.

[0003] Existing wire connector positioning fixtures primarily rely on fixed-size limiting grooves for support and positioning. This design exhibits significant limitations in adaptability when dealing with various wire connector specifications. Because different specifications of wire connectors differ considerably in geometric parameters such as diameter, length, and shape, fixed limiting grooves can only accommodate connectors within a specific size range. When handling larger or smaller connectors, either the limiting groove is too wide, causing the connector to wobble and fail to hold effectively, or the groove is too narrow, preventing the connector from being inserted at all or causing excessive compression and deformation after insertion. This limitation of "one groove cannot accommodate multiple connectors" forces companies to equip themselves with multiple sets of dedicated fixtures for different connector specifications. This not only increases equipment procurement costs and storage space usage but also necessitates frequent fixture changes during production line switchovers, severely impacting production efficiency and equipment utilization, and failing to meet the demands of modern manufacturing for flexible production and rapid response.

[0004] Therefore, a positioning bracket for crimping wire connectors is proposed to solve the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a positioning bracket for crimping wire connectors, which has the advantages of limiting the positioning of wire connectors of different specifications, ensuring the stable positioning of wire connectors, and being adaptable to various working heights.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A positioning bracket for crimping wire connectors includes a positioning bracket;

[0008] The positioning bracket is equipped with a bearing platform, and the bearing platform is equipped with a wire connector positioning mechanism.

[0009] The positioning bracket includes a support base, a vertical frame is vertically installed on the upper surface of the support base, a rectangular groove is opened on the front end face of the vertical frame and a threaded screw is rotatably installed in the groove, a screw nut is engaged with the outside of the screw, a slider seat is sleeved on the outside of the screw nut, and a connecting seat is connected to the side of the slider seat protruding from the support base.

[0010] The wire connector positioning mechanism includes a positioning plate disposed on the upper surface of the support platform. Two limiting frames are installed on the side of the positioning plate, and clamping frames are installed on the side of each of the two limiting frames.

[0011] Furthermore, both clamping frames are U-shaped with their openings on opposite sides; both clamping frames are threaded with positioning bolts.

[0012] Furthermore, rubber plates are installed on the sides of both limiting frames, and the rubber plates are installed between the limiting frame and the clamping frame.

[0013] Furthermore, the positioning bracket also includes a reciprocating motor disposed at the top of the vertical frame.

[0014] Furthermore, the output end of the reciprocating motor passes through the vertical frame and extends to connect with the top of the threaded screw.

[0015] Furthermore, it also includes a wire connector, which is supported above the support platform and located within the wire connector positioning mechanism.

[0016] In summary, this utility model has the following beneficial effects:

[0017] 1. This application achieves high-precision adaptive positioning of wire connectors of different specifications by setting up a vertical adjustment mechanism consisting of a support base, a vertical frame, a threaded screw, a screw nut, a slider seat, and a connecting seat, in conjunction with a wire connector positioning mechanism on the bearing platform, thereby providing different working heights.

[0018] 2. Traditional fixed fixtures often only accommodate wire connectors of specific specifications, requiring multiple sets of dedicated fixtures for workpieces of different sizes. This not only increases equipment investment costs but also affects the changeover efficiency of the production line. This application utilizes an adjustable positioning system composed of a positioning plate, a limiting frame, and a U-shaped opposing clamping frame. Combined with the precise adjustment function of the positioning bolts, it can flexibly adapt to the clamping needs of various wire connector specifications, significantly reducing the number of dedicated tooling fixtures, lowering equipment configuration costs, and improving the versatility and flexibility of the production line.

[0026] First embodiment;

[0027] Reference Figure 1-4 As shown, a positioning bracket for crimping wire connectors is provided in a preferred embodiment of the present invention, including a positioning bracket 2.

[0028] The positioning bracket 2 is equipped with a bearing platform 3, and the bearing platform 3 is equipped with a wire connector positioning mechanism 4;

[0029] The positioning bracket 2 includes a support base 21, a vertical frame 22 is vertically installed on the upper surface of the support base 21, a rectangular groove is opened on the front end face of the vertical frame 22 and a threaded screw 23 is rotatably installed in it, a screw nut 24 is engaged with the outside of the threaded screw 23, a slider seat 25 is sleeved on the outside of the screw nut 24, and the side of the slider seat 25 protrudes from the support base 21 and is connected to a connecting seat 26.

[0030] The wire connector positioning mechanism 4 includes a positioning plate 41 disposed on the upper end face of the bearing platform 3. Two limit frames 42 are installed on the side of the positioning plate 41, and clamping frames 43 are installed on the side of each of the two limit frames 42.

[0031] In this embodiment, a vertically mounted vertical frame 22 on the upper surface of the support base 21 forms a vertical support frame. A threaded screw 23 is rotatably mounted in a rectangular groove on the front end face of the vertical frame 22. The threaded screw 23 and an externally meshing screw nut 24 form a threaded transmission pair. A slider seat 25 sleeved on the outside of the screw nut 24 achieves smooth linear motion. The side of the slider seat 25 protrudes from the support base 21 and connects to the connecting seat 26. The wire connector positioning mechanism 4 is installed through a positioning plate 41 set on the upper surface of the bearing platform 3. Two limit frames 42 are symmetrically mounted on the side of the positioning plate 41. Each limit frame 42 is equipped with a clamping frame 43 on its side, forming a double-sided clamping positioning system.

[0032] Second embodiment;

[0033] Reference Figure 3 As shown, both clamping frames 43 are U-shaped and their openings on both sides are opposite to each other; both clamping frames 43 are threaded with positioning bolts 44.

[0034] In this embodiment, both clamping frames 43 adopt a U-shaped opening structure design, and the opening directions of the two clamping frames 43 are opposite, forming a spatial layout for opposing clamping. This opposing U-shaped structure can effectively surround and fix wire connectors 1 of different specifications, ensuring the stability and adaptability of clamping. Each clamping frame 43 is equipped with a positioning bolt 44 by a threaded connection. The operator can precisely adjust the clamping distance and clamping pressure between the clamping frames 43 by rotating the positioning bolt 44, so as to achieve precise adaptation and firm clamping of wire connectors 1 of different sizes and shapes. The threaded adjustment mechanism of the positioning bolt 44 is not only simple and intuitive to operate, but also has high adjustment accuracy. It can be fine-tuned according to the specific crimping process requirements to meet the production needs of high-precision positioning and repeatable positioning.

[0035] Third embodiment;

[0036] Reference Figure 3 As shown, rubber plates 45 are installed on the sides of both limit frames 42, and the rubber plates 45 are installed between the limit frame 42 and the clamping frame 43.

[0037] In this embodiment, rubber plates 45 are installed on the sides of both limiting frames 42, and the rubber plates 45 are precisely installed in the contact area between the limiting frame 42 and the clamping frame 43. The rubber plates 45 have multiple functions: First, the softness of the rubber material can effectively prevent surface scratches, indentations or other mechanical damage caused by direct hard contact between the clamping frame 43 and the wire connector 1; second, the elastic cushioning properties of the rubber plates 45 can provide appropriate cushioning force and distributed pressure during clamping, avoiding excessive concentrated clamping force from causing local deformation or damage to the wire connector 1; finally, the frictional properties of the surface of the rubber plates 45 can also enhance the stability and reliability of clamping, effectively preventing unwanted displacement or slippage of the wire connector 1 during crimping operations, ensuring the accuracy of the crimping position and the consistency of the crimping quality.

[0038] Fourth embodiment;

[0039] Reference Figure 1-2 As shown, the positioning bracket 2 also includes a reciprocating motor 27 disposed at the top of the vertical frame 22.

[0040] In this embodiment, the reciprocating motor 27 is installed at the top of the vertical frame 22 and can provide stable and reliable bidirectional rotational power output. The forward and reverse rotation of the motor directly drives the threaded screw 23 to rotate in the corresponding bidirectional direction, and then drives the screw nut 24 and the slider seat 25 to perform precise reciprocating linear motion through the threaded transmission mechanism.

[0041] Fifth embodiment;

[0042] Reference Figure 1-2 As shown, the output end of the reciprocating motor 27 passes through the vertical frame 22 and extends to connect with the top of the threaded screw 23.

[0043] In this embodiment, the output end of the reciprocating motor 27 adopts a straight-through connection design, with the motor output shaft directly penetrating the internal space structure of the vertical frame 22 and precisely extending to achieve a rigid coaxial connection with the top of the threaded screw 23. This direct connection method without intermediate transmission links ensures the highest efficiency and best reliability of power transmission.

[0044] Sixth embodiment;

[0045] Reference Figure 4 As shown, it also includes a wire connector 1, which is supported above the support platform 3 and located within the wire connector positioning mechanism 4.

[0046] In this embodiment, the wire connector 1 is precisely supported above the working area of ​​the support platform 3 during operation, and is completely within the effective clamping range and control space of the wire connector positioning mechanism 4. The wire connector 1 obtains a stable and reliable bottom support foundation through the support platform 3, and is simultaneously clamped and fixed from the side by two clamping frames 43 in the wire connector positioning mechanism 4. This ensures the positional stability and directional consistency of the wire connector 1 throughout the crimping process, and provides a precise and reliable workpiece positioning foundation for subsequent automated crimping equipment operations, effectively preventing crimping quality problems and processing accuracy deviations caused by workpiece displacement, deflection, or vibration.

[0047] Specific implementation process

[0048] Step 1: First, place the wire connector 1 above the support platform 3, ensuring it is within the working range of the wire connector positioning mechanism 4. At this point, the support base 21 provides a stable foundation for the entire device. The vertical frame 22 is vertically mounted on the upper surface of the support base 21, and the threaded rod 23, rotatably mounted within the rectangular groove on its front end face, is in its initial position. The threaded rod nut 24 engages externally with the threaded rod 23, achieving a secure connection through the outer sliding block seat 25 and the connecting seat 26. The entire transmission system is prepared for subsequent precise positioning and adjustment.

[0049] Step 2: Start the reciprocating motor 27 located at the top of the vertical frame 22. Its output end passes through the vertical frame 22 and is connected to the top of the threaded screw 23, driving the threaded screw 23 to rotate. Through the threaded engagement of the screw nut 24, the slider seat 25 and the connecting seat 26 move up and down within the vertical frame 22, thereby adjusting the height of the bearing platform 3. At the same time, the positioning plate 41 located on the upper surface of the bearing platform 3 moves accordingly, and the two limiting frames 42 installed on the side of the positioning plate 41 also adjust their height accordingly, so that the two U-shaped clamping frames 43 installed on the side of the limiting frames 42 can approach the target position of the wire connector 1.

[0050] Step 3: After the clamping frame 43 is adjusted to the appropriate height, the wire connector 1 is positioned by double-sided enclosure using the U-shaped structure of both clamping frames 43 with opposing openings on both sides. The clamping force and position of the wire connector 1 are precisely adjusted and fine-tuned by rotating the positioning bolts 44 threaded onto the two clamping frames 43. During this process, the rubber plate 45 installed between the limiting frame 42 and the clamping frame 43 plays an important buffering and protective role, preventing direct contact between metal parts and the wire connector 1 and causing surface damage, while also enhancing clamping stability. Ultimately, the wire connector 1 is accurately positioned and firmly clamped on the support platform 3, providing stable and reliable workpiece fixing conditions for subsequent crimping processes.
