Description

Technical Field

[0001] This utility model relates to the field of explosive detonator technology, and more specifically, to a triple waterproof cable clip. Background Technology

[0002] There are several types of cable clips on the market: 1. The first type of cable clip has no waterproof function and can only be used in dry environments such as sunny days. In humid or extreme conditions, the product may short-circuit and the circuit may fail to connect, rendering it unusable. 2. The second type of cable clip uses silicone grease to cover the spring to achieve waterproofing. However, silicone grease is sticky during operation, pollutes the workshop environment, is inconvenient to operate, and has low assembly efficiency and is difficult to assemble. 3. The third type of cable clip has sealing rings on both the top and bottom covers, ensuring a seal between the top and bottom covers. However, this product is too expensive, has low production efficiency, and significantly increases labor costs. 4. The fourth type of cable clip is a waterproof cable clip that can operate normally in water depths of 20cm or 60cm. However, this type of cable clip cannot meet higher waterproofing requirements, such as in shallow seas or lakes where higher waterproofing is required. Utility Model Content

[0003] The technical problem to be solved by this utility model is that existing wire clips cannot meet the requirements of high waterproofing. In order to overcome the above-mentioned defects of the prior art, this utility model provides a triple waterproof wire clip.

[0004] This utility model provides a triple waterproof cable clip: including an upper cover and a lower shell. The lower shell is provided with a spring for the busbar and lead wire to be inserted. The upper cover is provided with a first reinforcing rib that is circumferentially closed. The lower shell is provided with a sealing ring around the spring. When the upper cover and the lower shell are closed, the first reinforcing rib and the sealing ring are interference-fitted. The sealing ring is also provided with a busbar sheath for the busbar to be inserted and a lead wire sheath for the lead wire to be inserted. The inner side of the sealing ring is also provided with a second reinforcing rib.

[0005] In the above design, the interference fit between the first reinforcing rib and the sealing ring allows the upper cover to be sealed and waterproofed by the first reinforcing rib pressing against the sealing ring when it is closed onto the lower shell. This surpasses the waterproof characteristics of traditional wire clamps, enabling the product to maintain normal and effective circuit connection and operation in humid and dusty environments such as rainy days, rivers, and lakes. The busbar sheath covers the outer diameter of the busbar, ensuring a tight fit between the busbar and the wire clamp, thus reducing the impact pressure of water on the gap. The second reinforcing rib further blocks or delays water ingress. The busbar sheath serves as the first layer of waterproofing, the first reinforcing rib and the sealing ring form the second layer, and the second reinforcing rib serves as the third layer. This triple waterproofing structure allows the wire clamp to operate normally in environments up to 5 meters deep.

[0006] In one possible implementation, the sealing ring is a rectangular frame structure surrounding the spring, and the sealing ring is integrally formed with the lower shell. Integrating the sealing ring with the lower shell reduces water leakage caused by gaps between components, resulting in better waterproofing of the cable clip.

[0007] In one possible implementation, one end of the busbar sheath is connected to the second reinforcing rib, and the other end extends out of the lower shell. Because the busbars in the line clamp are generally arranged horizontally, the travel distance of the busbar through the side wall of the line clamp is relatively short. Extending the busbar sheath out of the lower shell effectively extends the travel distance of the busbar, thereby further improving the waterproof performance of the line clamp.

[0008] In one possible implementation, the busbar sheath is positioned directly opposite the busbar slot of the spring within the lower housing, and a notch is provided on the busbar sheath; the lead wire sheath is positioned directly opposite the lead wire slot of the spring within the lower housing, and a notch is provided on the lead wire sheath. Positioning the busbar sheath and lead wire sheath directly opposite each other shortens the design dimensions of the busbar and lead wire sheaths, making the wire clamp structure more compact, reducing water ingress caused by bending and twisting, and improving waterproofing. The notch facilitates the insertion of the busbar or lead wire into the busbar or lead wire sheath.

[0009] In one possible implementation, the first reinforcing rib is a rectangular frame structure, and when the upper cover and lower shell are closed, the rectangular frame structure of the first reinforcing rib and the rectangular frame structure of the sealing ring are interference-fitted. Both the first reinforcing rib and the sealing ring are rectangular frame structures to better match the layout of the internal spring contacts in existing wire clips. This allows for the direct addition of the first reinforcing rib and sealing ring to the existing wire clip structure without altering the overall structure of the existing wire clip, facilitating industrialization.

[0010] In one possible implementation, the second reinforcing rib is a rectangular frame structure and is integrally formed with a sealing ring that also has a rectangular frame structure. The integral formation of the second reinforcing rib with the inner side of the sealing ring reduces gaps between components, decreases the possibility of water ingress, and provides better waterproofing.

[0011] In one possible implementation, the sealing ring is made of silicone, and the first and second reinforcing ribs are made of hard rubber. Suitable sealing ring and reinforcing rib materials can, while maintaining a sealing and waterproof function, further reduce the weight of the waterproof cable clip and facilitate manufacturing.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. While maintaining the existing appearance of the line card, develop as much internal space as possible, and mass production can be carried out using existing automated equipment.

[0014] 2. This allows the line card to remain in normal operation for four hours even when fully submerged in water up to 5 meters deep.

[0015] 3. A brand-new triple waterproof internal structure with an innovative design of busbar sheath + sealing ring + rectangular second reinforcing rib.

[0016] 4. A single sealing ring is all that is needed to achieve a high level of IP28 waterproof and dustproof rating. Attached Figure Description

[0028] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0029] See Figures 1-5 As shown in the figure, this application discloses a triple waterproof cable clip that can work at a water depth of five meters.

[0030] See Figure 1 The basic components of the wire clip in this embodiment are the same as those of a regular wire clip, without any overall changes. The wire clip includes an upper cover 1 and a lower shell 2. A spring 4 is disposed inside the lower shell 2. The upper cover 1 and the lower shell 2 are hinged and fixed, so that the upper cover 1 can be flipped to cover the lower shell 2. The hinged part between the upper cover 1 and the lower shell 2 can be referred to as the connecting bridge 3.

[0031] See Figure 1 and Figure 2 In this embodiment, the wire clip is a conventional design, with the main wire 5 arranged horizontally and the lead wire 7 arranged vertically. Furthermore, the lead wire 7 slot of the spring 4 is lower than the slot of its main wire 5, causing the lead wire 7 to run below the main wire 5.

[0032] The advantage of this utility model over the prior art is that, while maintaining the existing product dimensions and the installation requirements of existing mechanical automation equipment, it adopts a method of adding a flexible silicone waterproof sealing ring 9 to the lower shell 2. At the same time, the flexible waterproof sealing ring 9 is equipped with a triple waterproof structure consisting of a busbar sheath 6, a lead wire sheath 8, and a rectangular frame structure with raised ribs. When the upper cover 1 is folded down with the connecting bridge 3 as the center, the flexible sealing ring 9 of the lower shell 2 is squeezed by the reinforcing ribs of the upper cover 1. This allows the product to break through the original usage environment and can connect the circuit normally and work normally in humid and dusty environments such as rainy days, rivers, and lakes.

[0033] See Figure 2 and Figure 4 The specific design of the triple waterproof structure is as follows: the upper cover 1 has a first reinforcing rib 10 protruding inside; the lower shell 2 has a sealing ring 9 surrounding the spring 4; when the upper cover 1 and the lower shell 2 are closed, the first reinforcing rib 10 and the sealing ring 9 are press-fitted; the sealing ring 9 is also provided with a busbar sheath 6 for the busbar 5 to be inserted into, and a lead wire sheath 8 for the lead wire 7 to be inserted into; the inner side of the sealing ring 9 also has a second reinforcing rib 11 protruding inside. Because the second reinforcing rib 11 is located inside the sealing ring 9, and the first reinforcing rib 10 is set by compressing the sealing ring 9, the second reinforcing rib 11 is also located inside the first reinforcing rib 10. Therefore, from a waterproofing perspective, the first layer of the triple waterproof structure consists of the busbar sheath 6 and the lead wire sheath 8, the second layer consists of the first reinforcing rib 10 and the sealing ring 9, and the third layer consists of the second reinforcing rib 11.

[0034] Combined Figure 2 and Figure 4 To achieve better waterproofing, the sealing ring 9 has a rectangular frame structure that surrounds the outer periphery of the spring sheet 4 inside the lower shell 2, sealing the conductive parts cut at the spring sheet 4 within the sealing ring 9. Preferably, the sealing ring 9 is a rectangular frame structure surrounding the spring sheet 4, and the sealing ring 9 is integrally formed with the lower shell 2.

[0035] The busbar sheath 6 is positioned directly opposite the busbar 5 slot of the spring 4 inside the lower shell 2. One end of the busbar sheath 6 is connected to the second reinforcing rib 11, and the other end extends out of the lower shell 2. A notch 601 is provided on the busbar sheath 6 for the busbar 5 to be inserted. In fact, the busbar sheath 6 can also be integrally molded with the sealing ring 9, so that the entire wire clamp can be integrally injection molded, which also reduces the number of joints and further improves the waterproof effect.

[0036] The lead wire sheath 8 is positioned longitudinally along the wire clip, with a certain distance between it and the outer wall of the lower housing 2, so it does not protrude outside the lower housing 2. However, the lead wire sheath 8 is also positioned directly opposite the lead wire 7 slot of the spring 4 inside the lower housing 2, and the lead wire sheath 8 also has a notch 601 for the lead wire 7 to be inserted into it. Like the busbar sheath 6, the lead wire sheath 8 can also be integrally formed with the sealing ring 9, serving as one of the waterproofing structures.

[0037] In some improved designs, to achieve better waterproofing, the height of the second reinforcing rib 11 can be higher than the height of the busbar sheath 6 and the lead wire sheath 8. The second reinforcing rib 11 has a rectangular frame structure and is integrally formed with the sealing ring 9, which also has a rectangular frame structure. The second reinforcing rib 11 is the structure closest to the spring 4, and its height can be higher than the height of the busbar sheath 6 and the lead wire sheath 8. This allows it to just block the gap caused by the compression between the first reinforcing rib 10 and the sealing ring 9, preventing the joint line from being directly opposite the spring 4 and blocking water from contacting the spring 4, thus achieving better waterproofing.

[0038] In this embodiment, the waterproof structure of the single sealing ring 9 of the wire clip is obtained by molding a mold and then heating and injection molding it using a vertical injection molding machine. This process has higher precision than assembly and produces products of better quality.

[0039] In this embodiment, the one-piece silicone sealing ring 9 is formed as a reinforcing rib of the lower shell 2, corresponding to the outer ring position of the spring 4 in the lower shell 2, so that the sealing ring 9 and the lower shell 2 form a single component.

[0040] In this embodiment, an automated device is used to fasten the upper cover 1 and the lower shell 2 together as a complete unit via a connecting bridge 3.

[0041] In this embodiment, the lead wire 7 is pressed into the spring sheet 4 of the lower shell 2 using an automatic lead wire pressing machine, and then the exposed position of the lead wire 7 is fastened to the lead wire sleeve 8 of the sealing ring 9.

[0042] In this embodiment, when used in the field, the busbar 5 needs to be inserted into the busbar sheath 6 through the notch 601 of the busbar sheath 6.

[0043] Finally, by rotating the upper cover 1 with the connecting bridge 3 as the center, the upper cover 1 and the lower shell 2 are locked together, creating a continuous compressive force that forms a sealed space inside the cable clamp. This structure allows the cable clamp to function normally for four hours in an environment with a water depth of five meters.

[0044] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
