Abstract
Description
Technical Field
[0001] This disclosure relates to the technical field of power cables, and in particular to a waterproof power cable assembly and a golf cart. Background Technology
[0002] Currently, golf carts are course vehicles developed specifically for golf courses, and they are an indispensable means of transportation for golf courses. They help players move quickly and conveniently on the golf course, thereby improving playing efficiency and saving energy.
[0003] The power system of a golf cart consists of multiple branch cables, and the terminals of each branch cable must be precisely connected to the corresponding interface of the vehicle's electrical module. Given the large number of branch cables, the traditional practice is to attach a sticker label with the interface number to each cable so that workers can correctly connect the different branch cable terminals to the corresponding interfaces of the electrical module.
[0004] However, this approach has significant drawbacks. After prolonged use, the adhesive strength of the stickers weakens considerably, making them prone to detachment. Furthermore, when the golf cart travels on uneven surfaces, the stickers on the branch cables rub and collide with each other due to the cart's movement. Since the stickers are easily worn, the lettering on them becomes blurred, increasing the difficulty of maintaining the golf cart. In addition, the branch cables and terminals are frequently damaged or even separated due to pulling during use, significantly increasing the maintenance costs of the golf cart. Utility Model Content
[0005] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a waterproof power cable assembly and golf cart that can not only reduce maintenance difficulty but also reduce maintenance costs.
[0006] The purpose of this disclosure is achieved through the following technical solution:
[0007] A waterproof power cable assembly for mounting a power unit on a golf cart, comprising:
[0008] The main cable is used for electrical connection with the energy storage module of the power unit;
[0009] Several branch cables, each of which is fixed and electrically connected to the main cable;
[0010] A plurality of connection terminals, each of which is electrically connected to a corresponding branch cable, and the plurality of connection terminals are used to electrically connect to the corresponding power terminal of the power module of the power unit.
[0011] The waterproof power cable assembly also includes several heat shrink tubes, with each end of the heat shrink tubes respectively fitted onto a corresponding connecting terminal and a corresponding branch cable, so that the connecting terminal is sealed and fixedly connected to the branch cable through the heat shrink tube; the outer peripheral wall of the heat shrink tube has a laser-printed surface.
[0012] In one embodiment, the main cable includes a waterproof protective layer, a first shielding layer, and a first insulating layer arranged sequentially from the outside to the inside, with the first insulating layer sleeved on the outer periphery of the plurality of branch cables.
[0013] In one embodiment, each branch cable includes, from the outside to the inside, a branch cable waterproof protective layer, a second shielding layer, a second insulation layer, and a conductor.
[0014] In one embodiment, the outer peripheral wall of the main cable has a plurality of branch openings, each of which penetrates the waterproof protective layer, the first shielding layer and the first insulation layer of the main cable, and the plurality of branch cables extend to the outside of the main cable through the corresponding branch openings.
[0015] In one embodiment, the conductor is an oxygen-free copper conductor.
[0016] In one embodiment, the main cable waterproof protection layer includes a first main cable waterproof protection layer and a second main cable waterproof protection layer, wherein the first main cable waterproof protection layer is sleeved on the first shielding layer, and the second main cable waterproof protection layer is sleeved on the first main cable waterproof protection layer.
[0017] In one embodiment, the branch cable waterproof protection layer includes a first branch cable waterproof protection layer and a second branch cable waterproof protection layer, wherein the first branch cable waterproof protection layer is sleeved on the second shielding layer, and the second branch cable waterproof protection layer is sleeved on the first branch cable waterproof protection layer.
[0018] In one embodiment, the main cable waterproof protective layer is a polyurethane mixed wear-resistant layer, and the branch cable waterproof protective layer is also a polyurethane mixed wear-resistant layer.
[0019] In one embodiment, the main cable waterproof protective layer is a thermoplastic elastic protective layer, and the branch cable waterproof protective layer is also a thermoplastic elastic protective layer.
[0020] In one embodiment, the first insulating layer is a cross-linked polyethylene insulating layer, and the second insulating layer is also a cross-linked polyethylene insulating layer.
[0021] In one embodiment, the laser-printed surface of each heat shrink tubing is provided with an interface number identifier corresponding to the connection terminal.
[0022] A golf cart includes a power unit and a waterproof power cable assembly as described in any of the above embodiments, wherein the main cable is electrically connected to the energy storage module of the power unit, and the connection terminal is electrically connected to the power consumption module of the power unit.
[0023] Compared with the prior art, this disclosure includes, but is not limited to, the following advantages:
[0024] 1. The aforementioned waterproof power cable assembly also includes several heat shrink tubing tubes. The two ends of each heat shrink tubing tube are respectively fitted onto corresponding connecting terminals and corresponding branch cables. This allows the connecting terminals to be sealed and fixed to the branch cables via the heat shrink tubing, ensuring the connecting terminals are securely fixed to the branch cables. This effectively prevents the branch cables from separating from their corresponding connecting terminals due to external factors during use, significantly reducing the possibility of damage to the waterproof power cable assembly and thus greatly reducing the maintenance costs of the golf cart. Simultaneously, the heat shrink tubing also prevents external water from entering the branch cables through the gaps between them and their corresponding connecting terminals, greatly reducing the possibility of short-circuit damage to the waterproof power cable assembly and further reducing the maintenance costs of the golf cart.
[0025] 2. Because the outer wall of the heat shrink tubing has a laser-printed surface, workers can print the interface number of the connection terminal onto the laser-printed surface of the heat shrink tubing. Compared with the traditional method of applying stickers and labels, the heat shrink tubing disclosed herein can be fixed on the waterproof power cable assembly for a long time. At the same time, it can effectively prevent the interface number on the laser-printed surface from becoming illegible due to friction and collision between the heat shrink tubing on each branch cable, greatly reducing the maintenance difficulty of golf carts.

[0034] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:
[0035] like Figures 1 to 4As shown, a waterproof power cable assembly 10 of one embodiment is used to install a power unit on a golf cart, including a main cable 100, a plurality of branch cables 200, a plurality of connecting terminals 300, and a plurality of heat shrink tubing 400; the main cable 100 is used for electrical connection to the energy storage module of the power unit; the plurality of branch cables 200 are all fixed to and electrically connected to the main cable 100; the plurality of connecting terminals 300 are respectively electrically connected to the corresponding branch cables 200, and the plurality of connecting terminals 300 are used for electrical connection to the corresponding power terminals of the power unit's power module; the two ends of the plurality of heat shrink tubing 400 are respectively sleeved on the corresponding connecting terminals 300 and the corresponding branch cables 200, so that the connecting terminals 300 are connected to the branch cables 200 through the heat shrink tubing 400. The sealed and fixed connection allows the connecting terminal 300 to be securely fixed to the branch cable 200 via the heat shrink tubing 400. This effectively prevents the branch cable 200 from separating from its corresponding connecting terminal 300 due to external factors during use, greatly reducing the possibility of damage to the waterproof power cable assembly 10 and thus significantly reducing the maintenance cost of the golf cart. At the same time, the heat shrink tubing 400 also prevents external water from entering the branch cable 200 through the gap between it and its corresponding connecting terminal 300, greatly reducing the possibility of short circuit damage to the waterproof power cable assembly 10 and further reducing the maintenance cost of the golf cart.
[0036] like Figures 1 to 4 As shown, the outer peripheral wall of the heat shrink tubing 400 is further formed with a laser printing surface 410, so that the staff can print the interface number of the connection terminal 300 onto the laser printing surface 410 of the heat shrink tubing 400 by laser printing. Compared with the traditional method of applying stickers and labels, the heat shrink tubing 400 of this disclosure can be fixed on the waterproof power cable assembly 10 for a long time. At the same time, it can also effectively prevent the interface number on the laser printing surface 410 from becoming illegible due to friction and collision between the heat shrink tubing 400s on each branch cable 200, which greatly reduces the maintenance difficulty of the golf cart.
[0037] In this embodiment, during the construction of the waterproof power cable assembly 10, the branch cable 200 and its corresponding connection terminal 300 are sealed and fixed by the heat shrink tubing 400 to prevent the branch cable 200 from separating from its corresponding connection terminal 300 due to external factors during use. This also prevents external water from entering the branch cable 200 through the gap between the branch cable 200 and its corresponding connection terminal 300. Furthermore, the operator can use laser printing to print the interface number of the connection terminal 300 onto the laser printing surface 410 of the heat shrink tubing 400, effectively preventing the interface number on the laser printing surface 410 from becoming illegible due to friction and collision between the heat shrink tubing 400s on each branch cable 200.
[0038] The aforementioned waterproof power cable assembly 10 also includes several heat shrink tubing 400s. The two ends of each heat shrink tubing 400 are respectively fitted onto the corresponding connecting terminal 300 and the corresponding branch cable 200, allowing the connecting terminal 300 to be sealed and fixedly connected to the branch cable 200 via the heat shrink tubing 400. This ensures the connecting terminal 300 is securely fixed to the branch cable 200, effectively preventing the branch cable 200 from separating from its corresponding connecting terminal 300 due to external factors during use. This significantly reduces the possibility of damage to the waterproof power cable assembly 10, thereby greatly reducing the maintenance cost of the golf cart. Simultaneously, the heat shrink tubing 400 also prevents external water from entering the branch cable 200 through the gap between it and its corresponding connecting terminal 300, further reducing the possibility of short-circuit damage and further lowering the maintenance cost of the golf cart.
[0039] Furthermore, since the outer peripheral wall of the heat shrink tubing 400 has a laser printing surface 410, the staff can print the interface number of the connection terminal 300 onto the laser printing surface 410 of the heat shrink tubing 400 by laser printing. Compared with the traditional method of applying stickers and labels, the heat shrink tubing 400 disclosed herein can be fixed on the waterproof power cable assembly 10 for a long time. At the same time, it can also effectively prevent the interface number on the laser printing surface 410 from becoming illegible due to friction and collision between the heat shrink tubing 400s on each branch cable 200, which greatly reduces the maintenance difficulty of the golf cart.
[0040] like Figures 3 to 4As shown, in one embodiment, the main cable 100 includes a main cable waterproof protective layer 110, a first shielding layer 120, and a first insulation layer 130 arranged sequentially from the outside to the inside. The first insulation layer 130 is sleeved on the outer peripheral wall of the multiple branch cables 200. The main cable waterproof protective layer 110 can effectively prevent external water from entering the interior of the main cable 100, avoiding short circuit damage to the waterproof power cable assembly 10 due to external water entering the interior of the main cable 100, thereby extending the service life of the waterproof power cable assembly 10 and reducing the maintenance cost of the waterproof power cable assembly 10. The first shielding layer 120 can effectively reduce the electromagnetic interference received by the waterproof power cable assembly 10, ensure signal stability, and improve the operational stability of the waterproof power cable assembly 10. The first insulation layer 130 can electrically isolate the branch cables 200, preventing electric shock and short circuits caused by current leakage from the branch cables 200 to the external environment or other conductors during use, greatly improving the operational safety of the waterproof power cable assembly 10.
[0041] like Figures 3 to 4 As shown, in one embodiment, each branch cable 200 includes, from the outside to the inside, a branch cable waterproof protective layer 210, a second shielding layer 220, a second insulation layer 230, and a conductor 240. The branch cable waterproof protective layer 210 can effectively prevent external water from entering the interior of the branch cable 200, avoiding short circuit damage to the waterproof power cable assembly 10 due to external water entering the interior of the branch cable 200, thereby extending the service life of the waterproof power cable assembly 10 and reducing the maintenance cost of the waterproof power cable assembly 10; the second shielding layer 220 can effectively reduce the electromagnetic interference received by the waterproof power cable assembly 10. The second insulation layer 230 ensures signal stability and improves the operational stability of the waterproof power cable assembly 10. It also provides electrical isolation for the conductor 240, preventing electric shock and short circuits caused by current leakage from the conductor 240 to the external environment or other conductors during use, thus significantly improving the operational safety of the waterproof power cable assembly 10.
[0042] As 1 to Figure 3As shown, in one embodiment, the outer peripheral wall of the main cable 100 has multiple branch openings (not shown), each branch opening passing through the waterproof protective layer 110, the first shielding layer 120 and the first insulation layer 130 of the main cable. Multiple branch cables 200 extend to the outside of the main cable 100 through the corresponding branch openings, so that the waterproof power cable assembly 10 can be electrically connected to multiple power terminals of the power module.
[0043] like Figures 3 to 4 As shown, in one embodiment, conductor 240 is an oxygen-free copper conductor to improve the conductivity of conductor 240, reduce the resistance of conductor 240, thereby improving the transmission efficiency of waterproof power cable assembly 10 and greatly reducing energy loss.
[0044] like Figures 3 to 4 As shown, in one embodiment, the main cable waterproof protection layer 110 includes a first main cable waterproof protection layer 111 and a second main cable waterproof protection layer 112. The first main cable waterproof protection layer 111 is sleeved on the first shielding layer 120, and the second main cable waterproof protection layer 112 is sleeved on the first main cable waterproof protection layer 111, so as to further improve the waterproof performance and protection performance of the waterproof power cable assembly 10.
[0045] like Figures 3 to 4 As shown, in one embodiment, the branch cable waterproof protection layer 210 includes a first branch cable waterproof protection layer 211 and a second branch cable waterproof protection layer 212. The first branch cable waterproof protection layer 211 is sleeved on the second shielding layer 220, and the second branch cable waterproof protection layer 212 is sleeved on the first branch cable waterproof protection layer 211, so as to further improve the waterproof performance and protection performance of the waterproof power cable assembly 10.
[0046] like Figures 3 to 4 As shown, in one embodiment, the main cable waterproof protective layer 110 is a polyurethane mixed wear-resistant layer, and the branch cable waterproof protective layer 210 is also a polyurethane mixed wear-resistant layer, so as to improve the flexibility and wear resistance of the main cable waterproof protective layer 110 and the branch cable waterproof protective layer 210, thereby extending the service life of the main cable waterproof protective layer 110 and the branch cable waterproof protective layer 210, and further improving the protective performance of the waterproof power cable assembly 10.
[0047] like Figures 3 to 4As shown, in one embodiment, the main cable waterproof protective layer 110 is a thermoplastic elastic protective layer, and the branch cable waterproof protective layer 210 is also a thermoplastic elastic protective layer. Thermoplastic elastomers have high strength, good elongation at break and elasticity, as well as good sealing performance, so that both the main cable waterproof protective layer 110 and the branch cable waterproof protective layer 210 have good waterproof and protective performance. At the same time, thermoplastic elastomers have good processing convenience, which greatly reduces the production difficulty of the waterproof power cable assembly 10, thereby improving the production efficiency of the waterproof power cable assembly 10.
[0048] like Figures 3 to 4 As shown, in this embodiment, the normal operating temperature range of the thermoplastic elastomer is from -50°C to 100°C, in order to improve the applicability of the waterproof power cable assembly 10.
[0049] like Figures 3 to 4 As shown, in one embodiment, the first insulating layer 130 is a cross-linked polyethylene insulating layer, and the second insulating layer 230 is also a cross-linked polyethylene insulating layer. Cross-linked polyethylene has the characteristics of high pressure resistance, high volume resistivity, low dielectric loss and extremely low inductance, which greatly improves the stability and safety of the waterproof power cable assembly 10.
[0050] like Figure 2 As shown, in one embodiment, the laser-printed surface 410 of each heat shrink tubing 400 is provided with an interface number marking section (not shown) corresponding to the connection terminal 300, so that the operator can connect each connection terminal 300 to the corresponding power terminal of the power module by looking at the number marked on the interface number marking section on the laser-printed surface 410 of each heat shrink tubing 400, which greatly reduces the maintenance difficulty of the golf cart and improves the ease of use of the golf cart.
[0051] This disclosure also provides a golf cart, including a power unit and a waterproof power cable assembly 10 as described in any of the above embodiments, wherein the main cable 100 is electrically connected to the energy storage module of the power unit, and the connection terminal 300 is electrically connected to the power consumption module of the power unit.
[0052] Compared with the prior art, this disclosure includes, but is not limited to, the following advantages:
[0053] 1. In the aforementioned golf cart, the waterproof power cable assembly 10 also includes several heat shrink tubing 400s. The two ends of each heat shrink tubing 400 are respectively fitted onto the corresponding connecting terminal 300 and the corresponding branch cable 200, so that the connecting terminal 300 is sealed and fixedly connected to the branch cable 200 through the heat shrink tubing 400. This ensures that the connecting terminal 300 is securely fixed to the branch cable 200 through the heat shrink tubing 400, effectively preventing the branch cable 200 from separating from its corresponding connecting terminal 300 due to external factors during use. This significantly reduces the possibility of damage to the waterproof power cable assembly 10, thereby greatly reducing the maintenance cost of the golf cart. Simultaneously, the heat shrink tubing 400 also prevents external water from entering the branch cable 200 through the gap between it and its corresponding connecting terminal 300, greatly reducing the possibility of short circuit damage to the waterproof power cable assembly 10, further reducing the maintenance cost of the golf cart.
[0054] 2. Furthermore, since the outer peripheral wall of the heat shrink tubing 400 has a laser printing surface 410, the staff can print the interface number of the connection terminal 300 onto the laser printing surface 410 of the heat shrink tubing 400 by laser printing. Compared with the traditional method of applying stickers and labels, the heat shrink tubing 400 disclosed herein can be fixed on the waterproof power cable assembly 10 for a long time. At the same time, it can also effectively prevent the interface number on the laser printing surface 410 from becoming illegible due to friction and collision between the heat shrink tubing 400s on each branch cable 200, which greatly reduces the maintenance difficulty of the golf cart.
[0055] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
