Description

Technical Field

[0001] The invention relates to a copper busbar, and more particularly to a copper busbar with a waterproof function. Background Art

[0002] Inside the car, many electrical components need to be connected through copper bars to form an electrical connection effect, such as electrical components such as batteries. The existing connection between the copper bar and the electrical component is only provided with an insulating protective sleeve on the connection to form an insulation protection effect at the connection. However, in order to improve the overall protection effect of the copper bar, an insulating layer is provided on the copper bar body to form an overall insulation effect. Both ends of the copper bar body are exposed to facilitate electrical connection. Here, the insulating layer is usually a heat shrink tube or injection molded onto the copper bar body.

[0003] The use of an insulating layer and an insulating protective sleeve can only ensure the overall insulation protection effect of the copper busbar. However, in some high-demand, standard-compliant cars, a waterproof effect is required, and this structure cannot achieve the waterproof effect, so a copper busbar with a waterproof function is urgently needed. Summary of the invention

[0004] The main technical problem solved by the invention is to provide a copper busbar with waterproof function.

[0005] The technical solution adopted by the present invention to solve the technical problem is: a copper busbar with waterproof function, including a copper busbar main body and an insulating sheath, an insulating layer is provided on the copper busbar main body, and fixing holes are provided on both ends of the copper busbar main body, wherein the insulating sheath has a main body part and a fixing part, the main body part is provided with a accommodating cavity with an opening and an upper cover, the upper cover is used to close the opening of the accommodating cavity, and a notch connected to the bottom is provided in the accommodating cavity; a fixing channel is provided on the fixing part, the fixing channel is sleeved on the insulating layer and fits with the insulating layer, one end of the copper busbar main body passes through the fixing channel and extends into the accommodating cavity, and the fixing hole is located in the vertical direction of the notch.

[0006] With this structural setting, the insulation layer is directly attached through the fixed channel to form a sealing strength between the insulation sheath and the insulation layer. With the setting of the upper cover and the receiving cavity, one end of the copper busbar body passes through the fixed channel and extends into the receiving cavity, and then is sealed by the upper cover, so that the sealing strength of the connection between the copper busbar and the electrical component is improved. When installing the external fasteners, the upper cover can be opened first, and then the fasteners can pass through the fixed holes and gaps and then connect to the electrical components at the lower end. Finally, the upper cover is overlapped to close the opening of the receiving cavity. At this time, the head of the fastener is located in the receiving cavity, which improves the overall protection effect. The copper busbar with this structure has a better waterproof effect.

[0008] The first channel is fitted with the exposed part, and the second channel is fitted with the insulating layer to form a double protection, ensuring that the insulating sheath and the copper busbar are fitted and protected as a whole. Since the cross-sectional area of ​​the copper busbar with the insulating layer is larger than the cross-sectional area of ​​the exposed part, it is necessary to ensure that the insulating sheath fits the insulating layer to form an overall waterproof effect to prevent liquid from flowing into the copper busbar from between the insulating layer and the exposed part.

[0009] Wherein, a waterproof convex rib is provided on the second channel.

[0010] The provision of waterproof ribs further improves the overall protection level.

[0011] Wherein, the waterproof convex rib is partially embedded in the second channel.

[0013] Among them, the insulating sheath includes a first component and a second component, the first component and the second component are detachably connected, the first component and the second component cooperate to form a first channel and a second channel, the first component is provided with a first rib, the second component is provided with a second rib, the first rib and the second rib cooperate to form a waterproof rib.

[0014] Two parts are used to form the insulating sheath as a whole, and two convex ribs are used to form a waterproof convex rib. The entire waterproof convex rib is installed in the insulating sheath, which is easy to be displaced or fall off, affecting the protective effect. Here, the convex rib is fixed to the component by secondary injection molding to form the fixation of the convex rib, reduce production costs, and make operation more convenient. Furthermore, a first extension portion is provided on the first convex rib, and a first recessed portion is provided on the second convex rib. The first extension portion cooperates with the first recessed portion to form a fit between the two convex ribs.

[0015] The upper cover is detachably connected to the main body, a waterproof protrusion is provided on the opening, and the inner wall of the upper cover is fitted with the outer wall of the waterproof protrusion.

The waterproof protrusion prevents liquid from entering the copper busbar from the connection between the upper cover and the main body. The waterproof protrusion further improves the overall waterproof effect.

[0017] The upper cover is detachably connected to the main body, and a waterproof groove adapted to the waterproof protrusion is provided on the upper cover, and the waterproof protrusion is embedded in the waterproof groove and fixed.

[0018] By setting the waterproof groove, a double protection effect is formed. Compared with the setting of a single waterproof protrusion, this structure further improves the overall protection level.

[0019] One end of the upper cover is hinged to the main body, and the other end is fixed to the main body in a snap-fit ​​manner.

[0020] The structure with one end hinged and the other end fixed by snap-on makes operation more convenient and the upper cover is not prone to the risk of falling off or being lost during use.

[0035] Embodiment 1:

[0036] Refer to the attached Figure 1 As shown, a copper busbar with waterproof function includes a copper busbar body 1 and an insulating sheath 2.

[0037] Refer to the attached Figure 2 As shown, an insulating layer 11 is provided on the copper busbar body 1, and exposed portions 12 are provided on both ends of the copper busbar body 1. The exposed portions 12 are provided with fixing holes 13, and the fixing holes 13 are used to connect and fix with electrical components to form electrical connections. Here, the insulating layer 11 is a heat shrink tube or injection molded onto the copper busbar body 1, so that the copper busbar body 1 forms a protective effect. The exposed portion 12 is specifically a position not covered by the insulating layer 11. Here, the structure of the copper busbar body 1 can be a straight busbar, a copper busbar with multiple bends, or an irregular copper busbar.

[0038] There are two insulating sheaths 2 , corresponding to the two exposed portions 12 respectively. The two insulating sheaths 2 have the same structure, so only the structure of one insulating sheath 2 is described here.

[0039] Refer to the attached Figure 3-9 As shown, the insulating sheath 2 includes a first component 3 and a second component 4, the first component 3 and the second component 4 are detachably connected, and the first component 3 and the second component 4 are spliced ​​to form a fixing portion 21 on the insulating sheath 2. Its specific structure is that a first clamping protrusion 31 is provided on the edge of the first component 3, and a first clamping groove 41 is provided on the edge of the second component 4, and the first clamping protrusion 31 cooperates with the first clamping groove 41 to achieve the matching and fixing of the first component 3 and the second component 4. Further, three first clamping protrusions 31 are respectively provided on both sides of the first component 3, and the number of the first clamping grooves 41 on the second component 4 corresponds to the number of the first clamping protrusions 31, so as to achieve the detachable connection between the first component 3 and the second component 4. The detachable connection method here is not only a snap-on fixation, but also can be hinged at one end and locked at the other end. The detachable connection is adopted. First, the production cost is reduced. Compared with integral injection molding, the processing is more convenient and the processing difficulty is reduced, thereby reducing the production cost. Second, it is easy to assemble. During assembly or transportation, the insulating sheath 2 can be directly fixed on the copper busbar body 1, which is convenient for transportation. During later installation, it can be directly installed and fixed without installing the insulating sheath 2.

[0040] The front end of the first component 3 is provided with a second extension portion 32, and the front end of the second component 4 is provided with a second recessed portion 42 adapted to the second extension portion 32. The first component 3 and the second component 4 cooperate to form a tight fit. Here, the second extension portion 32 and the second recessed portion 42 are located at the front end of the second channel.

[0041] The first component 3 and the second component 4 cooperate to form a fixed channel 23, and the fixed channel 23 includes a first channel 231 and a second channel 232. The cross-sectional area of ​​the first channel 231 is smaller than the cross-sectional area of ​​the second channel 232, and the two channels are connected by an inclined surface. Since the cross-sectional area of ​​the copper busbar body 1 with the insulating layer 11 is larger than the cross-sectional area of ​​the exposed part 12, it is necessary to ensure that the insulating sheath 2 fits with the insulating layer 11 to form an overall waterproof effect and prevent liquid from flowing into the copper busbar from between the insulating layer 11 and the exposed part 12. Therefore, the first channel 231 fits with the exposed part 12, and the second channel 232 fits with the insulating layer 11, forming double protection, ensuring that the insulating sheath 2 and the copper busbar are fitted and protected as a whole. The edge of the insulating layer 11 extends into the connection between the second channel 232 and the first channel 231. Moreover, through the detachable connection, compared with the sleeve in the prior art, the operation is simpler, and the fit rate between the insulating fixation and the copper busbar body 1 is better.

[0042] Furthermore, in order to improve the overall waterproof effect, a first rib 5 is provided on the first component 3, and a second rib 6 is provided on the second component 4. The first rib 5 and the second rib 6 cooperate to form a waterproof rib 7. The waterproof rib 7 is specifically located at the center of the second channel 232, and the waterproof rib 7 is partially embedded in the second channel 232. The waterproof rib 7 is embedded to further improve the overall waterproof level. That is, the waterproof rib 7 partially extends beyond the inner wall of the second channel 232, thereby improving the overall waterproof effect. Here, the top of the first rib 5 and the second rib 6 extending beyond the inner wall of the second channel 232 is in an arc shape, specifically a semicircular arc, so that the copper busbar body 1 has a further sealing effect during the fixing process.

[0043] Furthermore, the first convex rib 5 is provided with a first extension portion 51, and the second convex rib 6 is provided with a first recessed portion 61. The first extension portion 51 cooperates with the first recessed portion 61 to form a cooperation between the two convex ribs. The two components cooperate to form the insulating sheath 2 as a whole, and the two convex ribs cooperate to form the waterproof convex rib 7. Compared with the entire waterproof convex rib 7 installed in the insulating sheath 2, it is easy to be displaced or fall off, affecting the protective effect. Here, the convex rib is fixed to the component by secondary injection molding to form the fixation of the rib, reduce production costs, and make operation more convenient. For example, during the first injection molding, a convex rib groove is formed on the first component 3, and then the first convex rib 5 is partially embedded in the convex rib groove by secondary injection molding to form an overall connection and fixation. This structural setting can prevent the waterproof convex rib 7 from falling off during use, while reducing production costs.

[0044] The main body 22 is located on the first component 3. The main body 22 is provided with a receiving cavity 221 with an opening 222 and an upper cover 8. The upper cover 8 is used to close the opening 222 of the receiving cavity 221. Here, the upper cover 8 and the main body 22 are detachably connected. The specific structure is that one end of the upper cover 8 is hinged to the main body 22, and the other end is fixed to the main body 22 in a snap-fit ​​manner. One end of the upper cover 8 is integrally injection-molded with the main body 22 to form a flexible portion 81, so that one end of the upper cover 8 is hinged to the main body 22. The other end of the upper cover 8 is provided with a second snap-fitting protrusion 82. The main body 22 is provided with a second snap-fitting groove 223 adapted to the second snap-fitting protrusion 82. The second snap-fitting protrusion 82 cooperates with the second snap-fitting groove 223 to achieve the fixation of the upper cover 8. It should be noted here that after the second snap-in protrusion 82 of the upper cover 8 is matched with the second snap-in groove 223, the outer side wall of the upper cover 8 does not exceed the outer side wall of the main body 22, and the second snap-in groove 223 does not penetrate the outer side wall of the main body 22. The structure with one end hinged and the other end fixed by snap-in makes the operation more convenient, and the upper cover 8 is not prone to the risk of falling off or losing during use. Here, the upper cover 8 can also be directly connected and fixed to the main body 22 by an integral snap-in. Further, a handle 84 is also provided on the upper cover 8, and the user can open the upper cover 8 by the handle 84, and the handle 84 is specifically located above the same side of the second snap-in protrusion 82.

[0045] Furthermore, a waterproof protrusion 224 is provided on the opening 222. When the upper cover 8 is matched with the main body 22, the inner wall of the upper cover 8 fits with the outer wall of the waterproof protrusion 224 to form a waterproof effect, thereby preventing liquid from penetrating into the accommodating cavity 221 through the connection between the upper cover 8 and the main body 22.

[0046] A baffle 225 is provided in the accommodating cavity 221, and a notch 226 is formed between the baffle 225 and the inner wall of the accommodating cavity 221, and the notch 226 is connected to the bottom, so that the fastener 9 can pass through the fixing hole 13 and the notch 226 to connect with the electrical component to form an electrical connection. When one end of the copper busbar body 1 passes through the fixing channel 23 and extends into the accommodating cavity 221, the fixing hole 13 is located in the vertical direction of the notch 226, so that the fastener 9 can be better fixed. Here, the baffle 225 is an irregular shape, so that the exposed part 12 fits with the baffle 225, and the connection strength between the insulating sheath 2 and the copper busbar body 1 is improved.

[0047] Furthermore, a positioning protrusion 227 is provided on the accommodating cavity 221 , and the positioning protrusion 227 is located below the baffle 225 . A positioning groove 14 adapted to the positioning protrusion 227 is provided on the exposed portion 12 , so as to achieve a positioning and fixing effect of the copper busbar body 1 .

[0048] The upper cover 8 and the main body 22 are integrally formed. The integrally formed setting makes processing more convenient. That is, the first component 3 is integrally injection molded, and the first component 3 is formed by secondary injection molding, and the second component 4 is also formed by secondary injection molding, which makes the overall processing more convenient and reduces the processing cost. Here, the insulating sheath 2 is specifically made of insulating rubber material, so that the insulating sheath 2 as a whole has a certain flexibility.

[0049] With this structural setting, the insulating layer 11 is directly attached through the fixed channel 23 to form a sealing strength between the insulating sheath 2 and the insulating layer 11. The setting of the waterproof rib 7 further improves the sealing effect between the insulating sheath 2 and the insulating layer 11. With the setting of the upper cover 8 and the accommodating cavity 221, one end of the copper busbar body 1 passes through the fixed channel 23 and extends into the accommodating cavity 221, and then is sealed by the upper cover 8, so that the sealing strength of the connection between the copper busbar and the electrical component is improved. When installing the external fastener 9, the upper cover 8 can be opened first, and then the fastener 9 can pass through the fixing hole 13 and the notch 226 and then connected to the electrical component at the lower end. Finally, the upper cover 8 is overlapped to close the opening 222 of the accommodating cavity 221. At this time, the head of the fastener 9 is located in the accommodating cavity 221, which improves the overall protection effect. The copper busbar of this structure is directly installed together with the insulating sheath 2 during transportation. When installing the copper busbar, the installer only needs to open the upper cover 8, and then connect the two ends of the copper busbar to the electrical components through the fasteners 9 to form an electrical connection. The installation is very convenient and the waterproof effect is better.

[0050] Embodiment 2:

[0051] Refer to the attached Fig.10As shown, the difference between Example 2 and Example 1 is that a waterproof groove 83 adapted to the waterproof protrusion 224 is provided on the upper cover 8, and the waterproof protrusion 224 is embedded and fixed in the waterproof groove 83. The provision of the waterproof groove 83 forms a double protection effect, and compared with the provision of a single waterproof protrusion 224, this structure further improves the overall protection level.
