Description

Technical Field

[0001] This application relates to the field of linear assembly technology for electronic connectors, and more particularly to an auxiliary fixture for inserting wire cores. Background Technology

[0002] In the manufacturing process of cable connectors, it is often necessary to insert multiple wire cores into the inner shell and waterproof ring of the socket. Due to the large number of wire cores, their small diameter (e.g., 0.5mm to 2.0mm), and the dense arrangement of the sockets in the inner shell and waterproof ring, manual operation is not only inefficient but also prone to bending, misalignment, or damage of the wire cores, affecting the product qualification rate.

[0003] Currently, while some simple clamps or molds exist for securing socket assemblies, they are often single-function, unable to simultaneously handle the inner shell and waterproof ring, and lack effective wire guide and avoidance mechanisms. Furthermore, the significant dimensional differences between different socket assembly models mean that poorly compatible fixtures increase production costs. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide an auxiliary fixture for inserting wire cores, which can solve the above-mentioned problems existing in the prior art.

[0005] To achieve the above objectives, this application adopts the following technical solution: This disclosure provides an auxiliary fixture for inserting wire cores, comprising: The base has an installation surface, on which at least one first slot for placing the inner shell of the wire core socket and at least one second slot for placing the waterproof ring of the wire core socket are provided; The first slot and the second slot are respectively sunk into the mounting plane, and a plurality of avoidance openings for wire core avoidance are opened on the bottom surface of the first slot, and a plurality of guide slots for wire guidance are opened on the bottom surface of the second slot. The axial directions of the avoidance opening and the guide groove are respectively perpendicular to the mounting plane.

[0006] Preferably, the mounting plane is horizontal.

[0007] Preferably, the bottom of the base is provided with an opening groove, and the projection area of ​​the opening groove on the mounting plane can cover the second slot.

[0008] Preferably, the avoidance opening and the guide slot respectively penetrate the base, and the second slot communicates with the opening slot through the guide slot.

[0009] Preferably, the edge of the avoidance opening located on the bottom surface of the first slot is chamfered.

[0010] Preferably, the guide groove has a chamfered edge on the bottom surface of the second groove.

[0011] Preferably, the two edges of the second slot are respectively provided with part-retrieving slots, which are disposed on the base.

[0012] Preferably, the base is made of acetal steel.

[0013] Preferably, an embedded block can be snapped into the first slot and the second slot, and the embedded block has a slot and several through holes. The slot can be used to fit different sizes of wire core socket inner shells or wire core socket waterproof rings.

[0014] Preferably, a slider is slidably disposed in the first slot or the second slot, and the slider can be fixedly disposed relative to the base.

[0015] The beneficial effects of this application are as follows: 1. A stable reference platform is formed by a high-rigidity acetal alloy base, a highly flat horizontal mounting surface, and a recessed slot that precisely matches the shape of the component. This fundamentally eliminates tilting, displacement, and shaking of the component during wiring, ensuring that the relative position of each wire core socket remains fixed, providing a fundamental guarantee for subsequent precise wiring.

[0016] 2. Avoid ensuring the axis of the guide slot is perpendicular to the mounting plane, forcing the wire core to insert vertically and preventing oblique insertion. Additionally, a chamfer is provided along the edge of the slot to form a guiding slope, significantly reducing insertion force and preventing wire core head bending, jamming, and insulation layer scratches.

[0017] 3. A part removal slot is provided at the edge of the second slot, which can provide a force point for the operator or tool, so that the elastic and sticky waterproof ring can be easily and without damage, avoiding component deformation or damage caused by forced prying.

[0018] 4. By replacing the embedded blocks, components of different sizes and hole positions can be quickly adapted, achieving "one base, multiple models". This greatly enhances the versatility of the fixture, eliminating the need for dedicated fixtures for each product when dealing with multi-variety, small-batch production, significantly reducing tooling costs and production changeover time.

[0022] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0025] like Figures 1 to 4 As shown, this embodiment provides an auxiliary fixture for inserting wire cores, which can stably place the inner shell 10 of the wire core socket and the waterproof ring 20 of the wire core socket, and ensure that the wire core is effectively avoided and guided during the insertion process, thereby improving assembly accuracy and efficiency.

[0026] Specifically, the auxiliary fixture for wire core insertion provided in this disclosure includes a base 100, which supports the inner shell 10 of the wire core socket and the waterproof ring 20 of the wire core socket. By placing the inner shell 10 of the wire core socket and the waterproof ring 20 of the wire core socket on the base 100, it can be ensured that the inner shell 10 of the wire core socket and the waterproof ring 20 of the wire core socket are in a stable state during the assembly process.

[0027] In one embodiment, the base 100 may be made of acetal alloy, which possesses high rigidity, low moisture absorption, and chemical corrosion resistance. Acetal alloy maintains dimensional stability in humid environments. It is understood that the base 100, as the core load-bearing structure, combined with the high rigidity of the acetal alloy, can stably support the inner shell 10 of the wire core socket and the waterproof ring, preventing component wobbling caused by deformation of the fixture itself. Simultaneously, the low moisture absorption and chemical corrosion resistance of acetal alloy maintain dimensional stability in humid environments, further ensuring the long-term consistent positioning of the components and solving the positioning inaccuracy problem caused by material deformation or environmental influences in traditional fixtures.

[0028] Furthermore, the mounting plane 101 is located at the top of the base 100 and is horizontally positioned to ensure stable placement of the components. The mounting plane 101 is precision-machined, with a surface flatness error of less than 0.1mm, to prevent tilting during component placement. The first slot 110 and the second slot 120 are respectively formed on the mounting plane 101, and their number can be set according to production needs, for example, 2-4 of each, to handle multiple components simultaneously. The first slot 110 is used to house the inner shell 10 of the wire core socket, and the second slot 120 is used to house the waterproof ring 20 of the wire core socket. Both the first slot 110 and the second slot 120 are recessed into the mounting plane 101, with a depth generally between 5mm and 10mm. However, this is not the only limitation; the specific depth of the first slot 110 and the second slot 120 depends on the thickness of the component. The slot shape matches the component's shape; for example, the first slot 110 is rectangular to fit the rectangular inner shell 10 of the wire core socket, and the second slot 120 is oblong to fit the oblong waterproof ring 20 of the wire core socket.

[0029] It is understandable that by setting a highly flat horizontal mounting plane 101 and a recessed, dedicated first slot 110 and second slot 120, a precise positioning and stable support platform can be provided for the inner shell 10 of the wire core socket and the waterproof ring 20 of the wire core socket. This effectively prevents the components from tilting, shifting, or shaking during the wiring process, ensuring that the positions of all wire core sockets are fixed, laying a solid foundation for subsequent precise wiring.

[0030] Furthermore, a clearance opening 111 is provided on the bottom surface of the first slot 110. The number of clearance openings 111 corresponds to the number of insertion holes in the inner shell 10 of the wire core socket, for example, 8 or 12, for wire core clearance. A guide slot 121 is provided on the bottom surface of the second slot 120. The number of guide slots 121 corresponds to the wire holes of the waterproof ring 20 of the wire core socket. The axes of both the clearance opening 111 and the guide slot 121 are perpendicular to the mounting plane 101, which means that the wire core can be inserted vertically downwards, avoiding misalignment caused by oblique insertion. The diameter of the clearance opening 111 is slightly larger than the diameter of the wire core, for example, when the wire core diameter is 0.8mm, the diameter of the clearance opening 111 is 0.9mm, to provide a tight fit. At the same time, the diameter of the guide slot 121 is slightly larger than the diameter of the wire core, for example, when the wire core diameter is 0.8mm, the diameter of the guide slot 121 is 0.9mm, to provide guiding space.

[0031] It is understandable that the axes of both the avoidance port 111 and the guide slot 121 are perpendicular to the mounting plane 101, forcibly guiding the wire core to be inserted vertically downwards. This effectively avoids bending, misalignment, or damage to the wire core caused by oblique insertion. It effectively solves common problems in manual operation such as difficulty in aligning the wire core and improper insertion force, not only improving the success rate of single insertion but also significantly improving the overall assembly efficiency.

[0032] Meanwhile, the slight gap at the avoidance opening 111 ensures that the wire core does not wobble excessively after passing through the inner shell, maintaining accurate positioning. At the guide slot 121, a small amount of tolerance space is provided for the wire core, allowing it to be more easily guided into the correct path during initial insertion and smoothly transition to the avoidance opening 111. Therefore, friction and jamming between the wire core and the fixture are reduced, insertion resistance is lowered, and the insulation layer of the wire core is protected.

[0033] Please see Figure 1 In one embodiment, to facilitate the assembly of the wire core, an opening slot 130 may be provided at the bottom of the base 100. The opening slot 130 is a large cavity and can be formed by milling. The projection area of ​​the opening slot 130 on the mounting plane 101 covers the second slot 120, which means that the guide slot 121 can be directly viewed from the bottom. The avoidance slot 111 and the guide slot 121 respectively penetrate the base 100, and the second slot 120 communicates with the opening slot 130 through the guide slot 121.

[0034] Based on the above design, the wire core can extend from the bottom of the fixture, facilitating subsequent operations such as soldering, testing, or binding. Secondly, it reduces the weight of the fixture, lowering material costs. Finally, it facilitates cleaning and maintenance, as residue can be removed from the bottom.

[0035] Specifically, the depth of the opening slot 130 is generally 1 / 3 to 1 / 2 of the height of the base 100, for example, 20mm. However, it is not limited to this, and the depth of the opening slot 130 can be determined according to design requirements.

[0036] Please see Figure 1 In one embodiment, to improve the practical effect of the avoidance opening 111 and the guide slot 121, a chamfer can be provided at the edge of the avoidance opening 111 located on the bottom surface of the first slot 110, and a chamfer can be provided at the edge of the guide slot 121 located on the bottom surface of the second slot 120. Preferably, the chamfer angle is typically 45°, and the depth is 0.5mm to 1.0mm. By providing chamfers, the frictional resistance during wire core insertion can be significantly reduced. Specifically, the chamfer setting can reduce the insertion force of the wire core, while reducing the risk of scratching the wire core insulation layer. The chamfer can also guide the initial insertion of the wire core, avoiding bending or jamming of the wire core head.

[0037] It's important to note that chamfering can be achieved using a chamfering tool or a polishing process to ensure a smooth surface. Alternatively, for high-precision applications, the chamfer can be designed as a rounded shape to further optimize guiding performance.

[0038] It's understandable that the wire core head is relatively flexible and prone to "jamming" when encountering a sharp right-angle edge. For example, if the wire core head is bent by a sharp edge, it cannot be aligned with the hole. The chamfered surface can pre-guide the wire core head, so even if the wire core head is slightly off-center, it can naturally slide into the hole along the chamfered surface, avoiding repeated adjustments to the wire core position and improving assembly efficiency.

[0039] Please see Figure 1 In one embodiment, two corresponding retrieval slots 122 are provided along the two edges of the second slot 120. The retrieval slots 122 are semi-circular or U-shaped notches, with a width of 5mm to 10mm and a depth of 3mm to 5mm. The retrieval slots 122 allow the operator to easily remove the waterproof ring using tools (such as tweezers or a crochet hook) or fingers. Furthermore, the symmetrical distribution of the retrieval slots 122 ensures even force distribution.

[0040] Please see Figure 5 As shown, in one embodiment, to improve the applicability of the device and enable the base 100 provided by the device to adapt to different sizes of wire core socket inner shells 10 or wire core socket waterproof rings 20, an embedded block 200 can be provided in the first slot 110 and the second slot 120. The embedded block 200 is made of acetal or similar material and is fixed in the first slot 110 or the second slot 120 by a tight fit or magnetic attraction. The embedded block 200 has a slot 210 and several through holes 220. The size of the slot 210 can be adjusted according to the component; for example, a small slot is used for a waterproof ring with a diameter of 10 mm, and a large slot is used for a waterproof ring with a diameter of 15 mm. The through holes 220 are aligned with the avoidance opening 111 or the guide slot 121 to ensure unobstructed wire core passage.

[0041] It is understandable that the embedded block 200 enhances the versatility of this device, allowing it to handle multiple product models without replacing the entire base 100. For example, when switching products on the production line, only the embedded block 200 needs to be replaced, saving time and costs. The embedded block 200 can also be color-coded for easy identification. Through modular replacement, the embedded block 200 achieves the core objective of adapting a single base 100 to multiple models, improving versatility while also considering positioning accuracy, operational efficiency, and cost control.

[0042] It should be noted that the embedded block 200 uses the same acetal steel or similar material as the base 100, which has the same high rigidity, low moisture absorption and wear resistance, to avoid inconsistent thermal expansion and contraction due to material differences, and to ensure stable fit after long-term use, adapting to the environmental requirements of workshop temperature fluctuations.

[0043] Please see Figure 6As shown, in one embodiment, a slider 300 may be slidably disposed in the first slot 110 or the second slot 120. The slider 300 is made of metal or plastic and is connected to the base 100 via a guide rail 310. The position of the slider 300 can be fixed by screws or a quick-clamping mechanism to adjust the size or shape of the first slot 110 or the second slot 120. For example, for a rectangular first slot 110, the slider 300 can move to change the width of the first slot 110, thereby clamping inner shells of different sizes. The surface of the slider 300 may be provided with anti-slip texture to enhance clamping force.

[0044] Specifically, the slider 300 is connected to the guide rail 310 to achieve smooth sliding. With the help of screw locking or quick clamping mechanism (such as snap-on or knob type), the adjustment process does not require disassembly of any parts. For example, when switching from a 10mm inner shell to a 12mm inner shell, you only need to loosen the screw, push the slider 300 to the target position, and relock it.

[0045] Understandably, by adjusting slider 300, the fixture can quickly adapt to new components, reducing downtime.

[0046] Specifically, in actual use, the device first places the inner shell 10 of the wire core socket into the first slot 110, and then inserts the wire cores of the wire harness into the corresponding holes of the inner shell 10. Next, the waterproof ring 20 of the wire core socket is placed into the second slot 120, and all the pins corresponding to the wire cores, including the inner shell 10 of the wire core socket, are inserted into the waterproof ring 20.

[0047] In summary, this disclosure provides an auxiliary fixture for wire core insertion, which forms a stable reference platform through a high-rigidity acetal alloy base 100, a highly flat horizontal mounting plane 101, and a recessed slot precisely matching the shape of the component. This fundamentally eliminates tilting, displacement, and shaking of the component during insertion, ensuring that the relative position of each wire core insertion hole remains fixed, thus providing a fundamental guarantee for subsequent precise insertion.

[0048] Meanwhile, the axis of the guide slot 121 is perpendicular to the mounting plane 101, which avoids the opening 111 and guide slot 121, thus forcing the wire core to be inserted vertically and preventing oblique insertion. In addition, a chamfer is set at the edge of the slot to form a guide slope, which significantly reduces the insertion force and avoids bending, jamming, and scratching of the insulation layer of the wire core head.

[0049] A part removal slot 122 is provided at the edge of the second slot 120, which can provide a force point for the operator or tool, so that the elastic and sticky waterproof ring can be easily and without damage, avoiding component deformation or damage caused by forced prying.

[0050] By replacing the embedded block 200, components of different sizes and hole positions can be quickly adapted, achieving "one base for 100, multiple models". This greatly enhances the versatility of the fixture, eliminating the need for a dedicated fixture for each product when dealing with multi-variety, small-batch production, significantly reducing tooling costs and production changeover time.
