Description

Technical Field

[0001] This utility model relates to the field of automotive power equipment technology, and in particular to an automotive starter power supply that is easy to wire. Background Technology

[0002] Car jump starters (also known as emergency jump starters or battery jumpers) are portable emergency power supply devices widely used when vehicles cannot start due to a dead battery. Traditional car jump starters typically consist of a housing and positive and negative terminals located on the side of the housing. To use them, the user connects the clamps of the included jumper cables to these terminals and clamps the other end of the cables to the corresponding terminals on the vehicle battery to perform a jump start.

[0003] However, existing products of this type still have some obvious inconveniences and potential hazards in practical use. First, due to the limited space on the side of the casing and its typically flat design, the wires and clamps often lack stable support during wiring operations, making them prone to dangling or wobbling, especially in the confined space of an engine compartment, increasing the difficulty of alignment and clamping. Second, the direction of the wires after connection from the terminals is arbitrary, and multiple wires are easily tangled or interfere with other components in the compartment, not only appearing messy but also potentially causing the connection points to loosen due to vehicle vibration, affecting the reliability of current transmission and even posing a short circuit risk. Furthermore, most existing products do not effectively guide and manage the wire lead-out path, and the wire joints are easily subjected to improper bending or pulling, which may damage the cables or terminals with long-term use.

[0004] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an easy-to-wire car starting power supply to solve one or more problems existing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a car starter power supply that facilitates wiring, comprising a housing and at least one terminal disposed on the side panel of the housing, and further comprising: A wiring platform is located adjacent to and below the wiring terminals, and a stepped support portion is formed on the side panel; The cable management assembly includes a detachably connected clip and a wire cylinder. The clip is fixed to the wiring platform and has a ring-shaped clamping structure. The wire cylinder is detachably housed within the clip by an elastic locking element. The wire cylinder has a through hole along its axial direction for guiding the wire direction. One end of the wire is connected to the terminal block, and the other end extends to the outside through the through hole.

[0007] In one embodiment of the present invention, the cross-section of the wire cylinder is a regular polygon, and the inner sidewall of the buckle is provided with a limiting protrusion that matches the regular polygon to restrict the rotational freedom of the wire cylinder relative to the buckle.

[0008] In one embodiment of the present invention, two elastic barbs are symmetrically arranged on the opening edge of the buckle, and the elastic barbs are engaged with the outer surface of the wire cylinder.

[0009] In one embodiment of this utility model, an insulating partition plate is integrally formed between two adjacent terminals, and the height of the insulating partition plate is not less than the protruding height of the terminals.

[0010] In one embodiment of the present invention, the outer shell is composed of a cover and a box that interlock with each other, and the cover and the box are detachably connected by screws or a snap-fit ​​structure; the box has a plurality of parallel-arranged receiving slots inside for fixing the power module.

[0011] In one embodiment of the present invention, the surfaces of both the cover and the box are densely covered with strip-shaped heat dissipation holes, and the inner walls of the heat dissipation holes are covered with a hydrophobic coating.

[0012] In one embodiment of this utility model, the cross-sectional shape of the threading hole is any one or more combinations of triangle, rhombus, square, and trapezoid.

[0013] In one embodiment of the present invention, the outer peripheral wall of the wire tube is provided with anti-slip texture extending along the length direction, and the inner wall of the buckle is provided with a corresponding protruding ridge adapted to the anti-slip texture, thereby improving the fit stability between the wire tube and the buckle.

[0014] As described above, the convenient car starter power supply of this utility model has the following beneficial effects: By integrating a wiring platform and modular cable management components, the functionality and practicality of the wiring structure are significantly optimized. The wiring platform uses a stepped support to provide physical support for the terminals, which not only strengthens the structural stability of the wiring area, but also naturally forms a buffer space for the wires through the height difference, effectively dispersing the impact of external forces on the interface. The cable management components adopt a combination design of split-type buckles and wire cylinders. The ring-shaped clamping structure provides flexible constraint on the root of the wire, while the elastic locking component ensures the flexibility of the cylinder's disassembly and assembly. The two work together to ensure that the wires always maintain a precise direction in dynamic environments. This dual fixing mechanism not only avoids the problem of poor contact caused by loose wires in traditional solutions, but also organizes messy cables into an orderly path through the axially penetrating wire hole, fundamentally eliminating the risk of insulation damage caused by wire friction and entanglement. The overall architecture takes into account both ease of operation and long-term reliability, meeting the user's need for quick plugging and unplugging, and maintaining a stable electrical connection under complex working conditions, fully reflecting the human-computer interaction thinking and engineering safety concept of industrial design.

[0018] This utility model provides a car starter power supply that is easy to wire. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. In the description of this utility model, it should be understood that the terms "up, down, left, right," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and should not be construed as limiting this utility model; in addition, the terms "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0019] Please see Figure 1 and Figure 2 This utility model provides an easy-to-connect automotive starter power supply, including a housing 1 and at least one terminal 2 disposed on the side panel of the housing 1, and further including: a wiring platform 3 located adjacent to and below the terminal 2, forming a stepped support portion on the side panel; a cable management assembly including a detachably connected buckle 4 and a cable tube 5, the buckle 4 being fixed to the wiring platform 3 and having an annular clamping structure; the cable tube 5 being detachably housed within the buckle 4 by an elastic locking member of the buckle 4, the cable tube 5 having an axially extending through-hole 6 for guiding the cable direction; one end of the cable being connected to the terminal 2, and the other end extending to the outside through the through-hole 6. Understandably, the wire cylinder 5 is made of a hard, wear-resistant insulating material, and has a through hole 6 extending through it along its axial direction. The wire cylinder 5 can be inserted into the receiving cavity of the annular clamping structure from the opening of the buckle 4, and is detachably fixed to the buckle 4 by the elastic locking action of the elastic locking member. The elastic locking member can undergo elastic deformation under external force to realize the disassembly and replacement of the wire cylinder 5. In use, one end of the wire is electrically connected to the terminal 2 by crimping or screwing, and the other end of the wire extends outward from the outer shell 1 after passing through the through hole 6 of the wire cylinder 5 along its axial direction. The through hole 6 effectively guides the direction of the wire.

[0020] The cross-section of the wire tube 5 is a regular polygon, and the inner sidewall of the buckle 4 is provided with limiting protrusions that match the regular polygon to restrict the rotational freedom of the wire tube 5 relative to the buckle 4. That is, when the wire tube 5 is housed in the receiving cavity of the buckle 4, each limiting protrusion abuts against the sidewall or inner corner of the regular polygon of the wire tube 5, thereby restricting the circumferential rotation of the wire tube 5 relative to the buckle 4 through mechanical limiting, and ensuring that the wire hole 6 of the wire tube 5 always maintains the preset guiding direction.

[0021] Two elastic barbs 7 are symmetrically arranged on the opening edge of the buckle 4. The elastic barbs 7 engage with the outer surface of the wire tube 5. When the wire tube 5 is inserted into the receiving cavity through the opening of the buckle 4, the outer surface of the wire tube 5 presses against the engaging surface of the elastic barbs 7, causing the two elastic barbs 7 to elastically deform outward. After the wire tube 5 is fully inserted into the receiving cavity, the elastic barbs 7 return to their original position under the action of their own elastic restoring force, and their bent end engaging surface tightly adheres to and engages with the outer surface of the wire tube 5. Through the engaging action of the two symmetrically arranged elastic barbs 7, the connection stability between the wire tube 5 and the buckle 4 is further improved, preventing the wire tube 5 from falling out of the receiving cavity of the buckle 4.

[0022] An insulating partition plate 8 is integrally formed between two adjacent terminals 2, and the height of the insulating partition plate 8 is not less than the protruding height of the terminal 2. The two side walls of the insulating partition plate 8 are close to the outer side walls of the two adjacent terminals 2, respectively, to achieve physical isolation between the adjacent terminals 2, and the top surface of the insulating partition plate 8 remains flat, which can also serve as an auxiliary support for the wires.

[0023] The outer casing 1 consists of a cover 9 and a box 10 that interlock with each other. The cover 9 and the box 10 are detachably connected by screws or latches. On the inner bottom wall of the box 10, multiple horizontally parallel receiving slots are integrally formed. The opening direction of the receiving slots is consistent with the fastening direction of the cover 9. The width and depth of the receiving slots are adapted to the external dimensions of the power module. The power module can be pushed into the receiving slot along the opening direction. The power module is fixed by the mechanical limiting effect of the receiving slot. Multiple parallel receiving slots can fix multiple power modules at the same time to meet different power supply needs.

[0024] Strip-shaped heat dissipation holes 11 are densely distributed on the outer and inner surfaces of the cover 9 and the box 10. The heat dissipation holes 11 are completely through the wall thickness of the shell, and the opening area of ​​the heat dissipation holes 11 on the cover 9 and the box 10 covers the main heat dissipation surface of the outer shell 1, ensuring air circulation between the inside and outside of the outer shell 1. A hydrophobic coating is uniformly covered on the inner wall surface of all the heat dissipation holes 11 by spraying and dipping, so as to achieve heat dissipation of the outer shell 1 and effectively prevent external water vapor and liquid from entering the interior of the outer shell 1 through the heat dissipation holes 11, avoiding moisture and short circuit of the internal circuit.

[0025] The cross-sectional shape of the wire-passing hole 6 on the conductor cylinder 5 can be any of the following shapes: triangular, rhomboid, square, or trapezoidal, depending on the actual conductor specifications and wire-passing requirements. Multiple shapes can also be combined. For a single shape, a square wire-passing hole 6 can be used to accommodate standard round conductors, or a trapezoidal wire-passing hole 6 can be used, utilizing the larger end of the trapezoid for easy wire insertion and the smaller end for wire restraint. For a combined shape, a combination of "trapezoidal at the entrance, square in the middle, and rhomboid at the exit," or other shapes, can be used. The inner walls of the wire-passing holes 6 are all smoothly polished to prevent scratches during wire insertion. Furthermore, the combined shapes of the wire-passing holes 6 can provide multi-segment guidance according to the conductor's direction, further improving the regularity of the conductor's path. It is understood that the guide cylinder can be freely replaced according to the actual conductor specifications. For example, when it is necessary to accommodate conductors with a larger diameter, a guide cylinder with a larger inner diameter can be used. If there are many conductors that need to be arranged in categories, a guide cylinder with multiple independent wire-passing holes 6 can be selected. During replacement, simply pull the original guide cylinder out of clip 4, then align the corresponding guide cylinder with the opening of clip 4 and snap it in place. The entire operation requires no complicated tools and can be completed by a single person in a short time. Furthermore, the guide cylinder can be made of high-strength ABS engineering plastic or aluminum alloy. The former has excellent insulation and corrosion resistance, making it suitable for humid or dusty automotive engine compartment environments; the latter offers superior heat dissipation and structural strength, maintaining shape stability during prolonged use and preventing deformation due to wire friction or temperature changes.

[0026] Optionally, continuous anti-slip patterns are integrally formed on the outer peripheral wall of the conductor tube 5 along its length. The anti-slip patterns adopt a strip-shaped groove structure or a strip-shaped protrusion structure, and multiple anti-slip patterns are evenly distributed along the circumference of the conductor tube 5. On the inner side wall of the annular clamping structure of the buckle 4, at positions corresponding to the anti-slip patterns on the outer peripheral wall of the conductor tube 5, several protruding ridges are integrally formed. The extension direction of the protruding ridges is consistent with the extension direction of the anti-slip patterns, and the cross-sectional shape and size of the protruding ridges are adapted to the groove shape and size of the anti-slip patterns. When the conductor tube 5 is accommodated in the receiving cavity of the buckle 4, the protruding ridges on the inner wall of the buckle 4 are precisely embedded in the anti-slip patterns on the outer peripheral wall of the conductor tube 5. Through the interlocking of the protruding ridges and the anti-slip patterns, the contact area and friction between the conductor tube 5 and the buckle 4 are increased, effectively preventing the conductor tube 5 from axially sliding or slightly shaking in the buckle 4, and improving the fit stability and connection firmness between the two.

[0027] In summary, this utility model of an easy-to-wire car starter power supply provides a suitable support foundation for wiring operations by setting a stepped support part of the wiring platform 3 near and below the terminal 2, which greatly improves the convenience and positioning accuracy of the wiring process. The matching cable management component adopts a structure in which the buckle 4 and the wire cylinder 5 are detachably connected. The combination of the ring clamping structure of the buckle 4 and the elastic locking part not only achieves the stable assembly and reliable fixation of each component of the cable management component, but also makes the disassembly and replacement of the cable management component more flexible and adaptable to different usage and maintenance needs. The axial through hole 6 on the wire cylinder 5 can effectively guide the wires connected to the terminal 2, keeping the wire arrangement neat and avoiding damage caused by messy tangling or random bending of the wires, ensuring the stability of the connection between the wires and the terminal 2. At the same time, the neat wire layout also makes subsequent inspection and maintenance operations easier to carry out. Overall, while optimizing the wiring operation experience, it effectively improves the reliability of the wire connection and the convenience of the overall equipment use and maintenance, and extends the service life of the wires and wiring structure. Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0028] It is understood that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of this utility model, and all such substitutions or changes should fall within the protection scope of this utility model.
