Description

Technical Field

[0001] This utility model relates to a battery holder, and more particularly to a battery holder with welded wires. Background Technology

[0002] In everyday life, battery holders are commonly used to house batteries. A typical battery holder includes an insulating body, a positive terminal, a negative terminal, a first wire, and a second wire. The insulating body has a receiving space for inserting the battery. The positive and negative terminals are used to solder to a circuit board, and the first and second wires are housed within the receiving space for direct soldering to the battery.

[0003] In existing battery holders, during manufacturing, one end of the first and second wires passes through the insulating base and enters the housing space to be welded to the battery. The first and second wires are relatively flexible and their shape after welding is difficult to control. Therefore, the first and second wires are prone to arching and occupying the battery installation space. Thus, after welding, the first and second wires need to be laid flat according to a preset path to ensure that the battery can be installed normally during use. This requires manual intervention, resulting in poor assembly efficiency and hindering automated assembly. Furthermore, since the first and second wires are directly welded to the battery, if the battery needs to be replaced, the entire wire and battery must be replaced, leading to high product costs.

[0004] Therefore, it is necessary to design an improved battery holder to overcome the above problems. Summary of the Invention

[0005] To address the problems encountered in the background technology, this utility model provides a battery holder. By setting a second receiving space on the insulating base, the positive and negative electrode welding parts are exposed in the second receiving space. The first wire and the second wire are welded to the positive and negative electrode welding parts in the second receiving space, thereby solving the problem that the first wire and the second wire are prone to arching and occupying the battery installation space. Furthermore, the first wire and the second wire are not directly welded to the battery, which facilitates battery replacement and saves costs.

[0006] To achieve the above objectives, the present invention employs the following technical means: A battery holder, comprising: An insulating base, the insulating base including a partition wall, a first enclosure wall and a second enclosure wall respectively arranged on the upper and lower sides of the partition wall, the first enclosure wall and the partition wall together form a first receiving space for accommodating the battery, and the second enclosure wall and the partition wall together form a second receiving space; The battery has a positive terminal and a negative terminal. The positive terminal includes a positive electrode contact portion exposed in the first housing space and a positive electrode welding portion exposed in the second housing space.

[0010] In one embodiment, the second receiving space further includes a limiting groove for limiting the positive electrode welding part. The first wire enters the limiting groove via a first guide section and welds to the positive electrode welding part. The limiting groove is connected to the first guide section, and there is an included angle between the limiting groove and the first guide section. The positive electrode welding part is at least partially embedded in the limiting groove. The depth of the limiting groove in the vertical direction is L, and the thickness of the positive electrode welding part in the vertical direction is H. Then, 0.5H≤L≤2.5H.

[0011] In one embodiment, the insulating base has a fixing groove extending through it in the vertical direction. The fixing groove is connected to the first receiving space and the second receiving space, and the positive terminal is fixed in the fixing groove. The positive terminal also includes a connecting part and a first elastic part connected to the positive electrode contact part, a stop part connected to the connecting part, and a fixing part connected to the first elastic part. The two sides of the connecting part are provided with limiting parts protruding toward the first receiving space. The positive terminal is inserted into the fixing slot, the fixing part is fixed to the fixing slot, the first elastic part bends and extends from the fixing part so that there is a gap between the first elastic part and the fixing part so that the positive contact part can elastically abut against the positive terminal of the battery, and the side of the blocking part near the first receiving space is blocked by a block in the fixing slot.

[0012] In one embodiment, the positive terminal further includes a second elastic portion extending from the lower end of the fixing portion. The second elastic portion extends downward and then upward from the lower end of the fixing portion and is connected to the positive electrode welding portion.

[0013] In one embodiment, the partition wall has a slot in the second receiving space, the slot extending upward through the first receiving space, and the negative electrode welding part is welded to one end of the second wire in the slot.

[0014] In one embodiment, the device further includes an upper cover and a lower cover. The upper cover covers the first receiving space to shield the battery, and the lower cover covers the second receiving space to shield the first wire and the second wire. A notch is provided on one side of the second enclosure. A wire outlet groove is provided on the upper side of the lower cover and / or on the lower side of the partition wall corresponding to the notch. The first wire and the second wire are partially confined in the wire outlet groove and pass through the notch.

[0015] In one embodiment, the first enclosure wall is provided with a pair of snap-fit ​​blocks, and the upper cover extends with a pair of elastic locking arms for engaging with the pair of snap-fit ​​blocks; the partition wall is provided with a snap-fit ​​portion, and the bottom cover extends toward the partition wall with a holding arm that engages with the snap-fit ​​portion; the side of the bottom cover away from the partition wall is also provided with a protruding structure 72 that protrudes downward toward the second receiving space for engaging with and fixing with a housing.

Therefore, there is independent space for placing the first and second wires, which does not occupy the battery installation space and is not directly welded to the battery. This facilitates battery replacement without requiring the replacement of the entire wire assembly, thus saving costs. Furthermore, the second receiving space provides an independent welding space for welding operations, offering ample operating space for setting welding point positions, facilitating welding operations, and promoting automated production of battery holder welding wires. Additionally, the other ends of the first and second wires extend outside the second receiving space, facilitating electrical connection with external electrical components.

[0017] Furthermore, the top cover is located in the first receiving space, protecting the upper surface of the battery and preventing it from falling out under long-term vibration, as well as preventing accidental ingestion by children. The bottom cover is located in the second receiving space, protecting the first and second wires within the second receiving space and preventing short circuits caused by exposed solder joints at the solder joints of the first and second wires. The top and bottom covers are separate structures; if one is damaged, it can be replaced individually, unlike battery holders with a one-piece cover structure where the entire unit must be replaced if one part is damaged, resulting in higher product costs.

[0023] like Figures 1 to 6 As shown, this is the battery holder 100 of the present invention. The battery holder 100 is used to accommodate a battery 200. Its structure includes an insulating base 1, a positive terminal 2, a negative terminal 3, a first wire 4, and a second wire 5. The insulating base 1 is provided with a first receiving space 14 and a second receiving space 15. The first receiving space 14 is used to accommodate the battery 200. Figure 9 , Figure 10As shown, battery 200 is a button cell. The side and top surfaces of battery 200 are the positive terminals, and the bottom surface is the negative terminal. The positive contact portion 21 of the positive terminal 2 and the negative contact portion 31 of the negative terminal 3 are used to contact the positive and negative terminals of battery 200 respectively. The second receiving space 15 is used to receive the first wire 4 and the second wire 5. The positive welding portion 22 of the positive terminal 2 and the negative welding portion 32 of the negative terminal 3 are exposed in the second receiving space 15. The first wire 4 and the second wire 5 are welded to the positive welding portion 22 and the negative welding portion 32 respectively in the second receiving space 15, providing independent space for welding the first wire 4 and the second wire 5 to the positive terminal 2 and the negative terminal 3. Meanwhile, the upper and lower sides of the insulating base 1 are respectively provided with an upper cover 6 and a bottom cover 7. The upper cover 6 covers the first receiving space 14 to cover the battery 200, and the bottom cover 7 covers the second receiving space 15 to protect the first wire 4 and the second wire 5. The bottom cover 7 is also provided with a protruding structure 72 protruding out of the second receiving space 15.

[0024] like Figures 1 to 6As shown, the insulating base 1 has a partition wall 12 and a first enclosure wall 11 and a second enclosure wall 13 connected to the partition wall 12. The first enclosure wall 11 and the second enclosure wall 13 are respectively arranged on the upper and lower sides of the partition wall 12. The first enclosure wall 11 extends upward from the outer edge of the partition wall 12 to form the first enclosure wall 11. The first enclosure wall 11 and the partition wall 12 together form a first receiving space 14. The second enclosure wall 13 extends downward from the outer edge of the partition wall 12 to form the second enclosure wall 13. The second enclosure wall 13 and the partition wall 12 together form a second receiving space 15. A notch 131 is opened on one side of the second enclosure wall 13. The upper side of the partition wall 12 forms the bottom surface of the first receiving space 14, and the lower side of the partition wall 12 forms the top surface of the second receiving space 15. The first receiving space 14 is used to receive the battery 200. A top cover 6 is placed over the first receiving space 14 to prevent the battery 200 from falling out during prolonged vibration and to prevent accidental ingestion by children. The second receiving space 15 is used to receive the first wire 4 and the second wire 5, providing independent space for welding the first wire 4 and the second wire 5 to the positive terminal 2 and the negative terminal 3. This eliminates the need for direct welding of the first wire 4 and the second wire 5 to the battery 200, facilitating battery replacement and saving costs by avoiding the need to replace the entire wire assembly. The bottom cover 7 seals the lower end of the second receiving space 15, preventing exposure of the first wire 4, the second wire 5, and their welding points. A fixing groove 18 and a slot 121 are formed on the left and right sides of the insulating base 1. The fixing groove 18 extends vertically through the insulating base 1. Specifically, the fixing groove 18 is recessed downwards from the top of the first enclosure wall 11 and extends through the partition wall 12, connecting the first receiving space 14 and the second receiving space 15. The slot 121 is formed by the partition wall 12 within the second receiving space 15, extending upwards through the first receiving space 14. The first enclosure wall 11 is interrupted at the location of the slot 121 to form an open opening, within which a pair of snap-fit ​​blocks 111 protrude on opposite sides. The partition wall 12 within the second receiving space 15 has a cable tray 16 for accommodating the first wire 4 and the second wire 5. The cable tray 16 includes a receiving section 163, a first guide section 161, and a second guide section 162. The first guide section 161 and the second guide section 162 connect to both sides of the receiving section 163, and their widths are both smaller than the width of the receiving section 163. The partition wall 12 facing the first receiving space 14 has a recessed retaining groove 123, which connects to the slot 121 to accommodate and fix the negative terminal 3. The partition wall 12 further has a recessed limiting groove 17 on the side facing the second receiving space 15. The limiting groove 17 communicates with the first guide section 161, and there is an included angle between the limiting groove 17 and the first guide section 161. The partition wall 12 also has a plurality of latching parts 122 recessed. In this utility model, there are four latching parts 122. In other embodiments, the number of latching parts 122 may also be set to other numbers, and no limit is made here.

[0025] like Figure 1 , Figure 7 , Figure 11 As shown, the positive terminal 2 and the negative terminal 3 are respectively arranged on the left and right sides of the insulating base 1. The positive terminal 2 is assembled into the fixing groove 18, and the negative terminal 3 is assembled and fixed in the retaining groove 123 on the partition wall 12 and exposed in the slot 121. The positive terminal 2 includes a positive electrode contact portion 21 and a positive electrode welding portion 22, a connecting portion 23 connected to the upper end of the positive electrode contact portion 21, a first elastic portion 24 connected to the lower end of the positive electrode contact portion 21, a stop portion 25 connected to the upper end of the connecting portion 23, and a fixing portion 26 connected to the first elastic portion 24. The two sides of the connecting portion 23 are provided with limiting portions 231 protruding towards the first receiving space 14. The positive terminal 2 also includes a second elastic portion 27 extending downward and then upward from the lower end of the fixing portion 26. The second elastic portion 27 is connected to the positive electrode welding portion 22 from the lower end of the fixing portion 26, so that the height of the positive electrode welding portion 22 is higher than the lowest point of the second elastic portion 27. The positive electrode contact 21 is exposed within the first receiving space 14. The positive electrode contact 21 protrudes from its upper and lower ends toward the side closest to the first receiving space 14, and its protruding portions directly contact the battery 200. The positive electrode welding portion 22 is raised by a second elastic portion 27 extending from the lower end of the fixing portion 26, allowing the height of the positive electrode welding portion 22 to extend into the limiting groove 17 for welding the first wire 4. The first elastic portion 24 extends from the bend of the fixing portion 26, creating a gap between the first elastic portion 24 and the fixing portion 26. After the battery 200 is inserted into the first receiving space 14, the battery 200 elastically contacts the positive terminal 2. The first elastic portion 24 provides elastic support to the positive electrode contact 21, ensuring good contact with the battery 200 and thus good conductivity.

[0026] like Figure 7 , Figure 8 , Figure 10As shown, a wire receiving groove 16 is provided on one side of the partition wall 12 within the second receiving space 15 to accommodate the first wire 4 and the second wire 5. The positive electrode welding part 22 and the negative electrode welding part 32 are arranged opposite each other at the left and right ends of the wire receiving groove 16. The wire receiving groove 16 includes a receiving section 163, a first guiding section 161, and a second guiding section 162. The receiving section 163 is located between the first guiding section 161 and the second guiding section 162, and connects the first guiding section 161 and the second guiding section 162. The first wire 4 and the second wire 5 partially pass through the second partition wall 1. After the notch 131 of the first conductor 4 enters the receiving section 163, a portion of the first conductor 4 is embedded in the first guiding section 161, and a portion of the second conductor 5 is embedded in the second guiding section 162. The widths of the first guiding section 161 and the second guiding section 162 are both smaller than the receiving section 163, which serves to guide the first conductor 4 and the second conductor 5 after they enter the receiving section 163, thereby guiding one end of the first conductor 4 (i.e., the welding end) and one end of the second conductor 5 (i.e., the welding end) to the positive electrode welding part 22 and the negative electrode welding part 32, respectively, to facilitate subsequent welding. The first guide section 161 and / or the receiving section 163 are further provided with a first clamping part 1611 to clamp both sides of the first wire 4, and the second guide section 162 and / or the receiving section 163 are provided with a second clamping part 1621 to clamp both sides of the second wire 5. The first clamping part 1611 and the second clamping part 1621 play a role in fixing the first wire 4 and the second wire 5, so that one end of the first wire 4 and one end of the second wire 5 will not shake when welding with the positive electrode welding part 22 and the negative electrode welding part 32, thus making welding easy and achieving good welding results. The first guide section 161 in the wire groove 16 is connected to the limiting groove 17, and the other end of the limiting groove 17 is connected to the fixing groove 18, so that the positive electrode welding part 22 can extend into the limiting groove 17. One end of the first wire 4 enters the limiting groove 17 through the first guide section 161 and is welded to the positive electrode welding part 22. The positive electrode welding part 22 is at least partially embedded in the limiting groove 17. The depth of the limiting groove 17 in the vertical direction is L, and the thickness of the positive electrode welding part 22 in the vertical direction is H. Then 0.5H≤L≤2.5H. Within this range, the degree of bending of the first wire 4 can still ensure that there is enough contact area with the positive electrode welding part 22 for welding, and the welding effect is good within this contact area range.

[0027] like Figures 1 to 3 As shown, when the battery holder 100 is not fitted with the battery 200, the positive terminal 2 is inserted into the fixing groove 18, the negative terminal 3 is assembled in the holding groove 123 of the partition wall 12, there is a gap between the positive contact part 21 and the fixing part 26, the side of the blocking part 25 near the first receiving space 14 is blocked by the blocking surface 19 on the side of the first enclosure wall 11, one end of the first wire 4 is welded to the positive welding part 22 in the limiting groove 17, and one end of the second wire 5 is welded to the negative welding part 32 in the slot 121.

[0028] like Figure 2 , Figure 3 and Figure 9 As shown, during the process of inserting the battery 200 into the first receiving space 14 from top to bottom, the battery 200 first pushes against the limiting part 231, causing the connecting part 23 to move away from the first receiving space 14 under the pushing force. This, in turn, causes the blocking part 25 to move away from the first receiving space 14. When the battery 200 is fully inserted into the battery holder 100, the positive electrode contact part 21 elastically contacts the battery 200. At this time, there is a distance between the blocking part 25 and the blocking surface 19. The limiting part 231 blocks the upper end surface of the battery 200, preventing the battery 200 from moving upward and improving the stability of the battery 200 installation. During this process, the fixing part 26 is always fixed in the fixing groove 18. After the battery 200 is inserted into the first receiving space 14, the negative electrode contact part 31 elastically abuts against the negative electrode of the battery 200, forming a stable contact.

[0029] like Figures 5 to 10As shown, after the battery 200 is fully inserted into the battery holder 100, the top cover 6 is placed on the first receiving space 14. A pair of elastic locking arms 61 extend from one side of the top cover 6 and engage with the snap-fit ​​block 111 on the first enclosure 11, thereby fixing the top cover 6 to the insulating base 1 and allowing the top cover 6 to cover the battery 200. The bottom cover 7 is placed on the second receiving space 15. The upper side of the bottom cover 7 and / or the lower side of the partition wall 12 are provided with a wire outlet groove G corresponding to the notch 131. The first wire 4 and the second wire 5 are partially confined in the wire outlet groove G. The wire outlet groove G limits the first wire 4 and the second wire 5 to prevent the first wire 4 and the second wire 5 from shaking and causing the solder joint at the welding position to loosen. The other end of the first wire 4 and the other end of the second wire 5 pass through the notch 131, so that the other end of the first wire 4 and the other end of the second wire 5 extend out of the second receiving space 15 for electrical connection with external electrical components, such as plugs or adapters. In this embodiment, both the upper side of the bottom cover 7 and the lower side of the partition wall 12 have wire outlet grooves G corresponding to the notches 131. In other embodiments, the wire outlet grooves G may be provided on only one of them, as long as they can limit the position of the first wire 4 and the second wire 5 passing through. The position of the wire outlet grooves G is not limited. The bottom cover 7 extends toward the partition wall 12 and has retaining arms 71, which cooperate with multiple latching parts 122 on the partition wall 12, so that the bottom cover 7 can be stably fixed to the insulating base 1 to seal the second receiving space 15 and prevent the first wire 4, the second wire 5 and the solder joints from being exposed. In this utility model, there are four retaining arms 71 provided on the bottom cover 7, which cooperate one-to-one with four latching parts 122. In other embodiments, the retaining arms 71 and the latching parts 122 may be set to other numbers. The number is not limited here, as long as the retaining arms 71 and the latching parts 122 can cooperate and fix them. The bottom cover 7 also has a protruding structure 72 on the side away from the partition wall 12, which protrudes downward into the second receiving space 15 and is fixed to the casing, thereby fixing the battery holder 100 to the external casing and facilitating the installation of the battery holder 100.

[0030] In summary, this utility model provides a battery holder 100, which has the following advantages compared with the prior art: 1. The positive electrode contact 21 and the negative electrode contact 32 are located in the first receiving space 14 and correspond to the positive and negative electrodes of the battery 200. The insulating base 1 is provided with a second receiving space 15 for independently accommodating the first wire 4 and the second wire 5. At the same time, the positive electrode welding part 22 and the negative electrode welding part 23 are exposed in the second receiving space 15. One end of the first wire 4 and one end of the second wire 5 are welded to the positive electrode welding part 22 and the negative electrode welding part 23 respectively in the second receiving space 15. Therefore, the insulating base 1 has an independent space to place the first wire 4 and the second wire 5, which will not occupy the installation space of the battery 200 and will not be directly welded to the battery 200. This makes it convenient to replace the battery 200 and does not require the replacement of the wires as a whole, thus saving replacement costs. In addition, the second receiving space 15 provides an independent welding space for welding operations, with a large operating space for setting the welding point position, which facilitates welding operations and is conducive to the automated production of welding wires in the battery holder 200. Furthermore, the other end of the first wire 4 and the other end of the second wire 5 extend out of the second receiving space 15, which facilitates electrical connection with external electrical components.

[0031] Furthermore, the top cover 6 is installed over the first receiving space 14 to protect the upper surface of the battery 200, preventing it from falling out of the first receiving space 14 under long-term vibration and preventing children from accidentally swallowing it. The bottom cover 7 is installed over the second receiving space 15 to protect the first wire 4 and the second wire 5 within the second receiving space 15, preventing short circuits caused by exposed solder joints at the welding points of the first wire 4 and the second wire 5. The top cover 6 and the bottom cover 7 are separate structures, so if one is damaged, it can be replaced separately, avoiding the situation where a battery holder with a one-piece cover structure requires replacement of the entire unit if one part is damaged, resulting in higher product costs.

[0032] 2. The second receiving space 15 is provided with a wire receiving groove 16, which is composed of a first guide section 161 on both sides, a second guide section 162 and a middle receiving section 163. The width of the first guide section 161 and the second guide section 162 is smaller than that of the receiving section 163. The first guide section 161 and the second guide section 162 guide the first wire 4 and the second wire 5 respectively, and can guide the first wire 4 and the second wire 5 to the positions of the positive electrode welding part 22 and the negative electrode welding part 32 respectively, so that the two wires can be directly welded to the positive electrode welding part 22 and the negative electrode welding part 32 respectively.

[0033] 3. The wire groove 16 is provided with a first clamping part 1611 and a second clamping part 1621 to clamp the first wire 4 and the second wire 5, and to fix the first wire 4 and the second wire 5 so that they will not move left or right during welding, thus facilitating welding.

[0034] 4. The limiting groove 17 is used to limit the positive electrode welding part 22. The relationship between the depth L of the limiting groove 17 and the thickness H of the positive electrode welding part 22 is: 0.5H≤L≤2.5H. Within this range, the first wire 4 does not need to be bent excessively to overlap with the positive electrode welding part 22. This ensures that the contact area between the first wire 4 and the positive electrode welding part 22 within this bending range is sufficient for welding, and the welding effect is good within this contact range.

[0035] 5. The insulating base 1 is provided with a through-hole fixing groove 18. The positive terminal 2 is inserted into the fixing groove 18. When the battery 200 is not inserted, the blocking surface 19 on one side of the first enclosure 11 blocks the blocking part 25 of the positive terminal 2, preventing the limiting part 231 of the positive terminal 2 from protruding excessively into the first receiving space 14 and making it impossible to insert the battery 200. The side of the fixing groove 18 away from the first receiving space 14 is used to block the fixing part 26 of the positive terminal 2, preventing the fixing part 26 of the positive terminal 2 from moving away from the first receiving space 14. The first elastic part 24 of the positive terminal 2 provides elastic support for the positive contact part 21, so that the positive contact part 21 and the battery 200 have good elastic contact. After the battery 200 is inserted, the limiting parts 231 on both sides of the connecting part 23 block the upper surface of the battery 200, preventing the battery 200 from moving upward, thus improving the stability of the battery 200 installation.

[0036] 6. One end of the second elastic part 27 extends from the fixed part 26, bends downward and then upward and extends to connect to the positive electrode welding part 22, so that the height of the positive electrode welding part 22 is higher than the lowest point of the second elastic part 27, thereby raising the positive electrode welding part 22 by a height, ensuring that the height of the positive electrode welding part 22 can extend into the limiting groove 17, thereby facilitating the welding of the first wire 4.

[0037] 7. A cable outlet groove G is provided on the upper side of the bottom cover 7 and / or the lower side of the partition wall 12 corresponding to the notch 131. The first wire 4 and the second wire 5 are partially confined in the cable outlet groove G and pass through the notch 131. The cable outlet groove G plays a limiting role for the first wire 4 and the second wire 5, preventing the first wire 4 and the second wire 5 from shaking and causing the solder joint to loosen. The notch 131 allows the other end of the first wire 4 and the other end of the second wire 5 to pass through and extend into the second receiving space 15, so that the other end of the first wire 4 and the other end of the second wire 5 can be connected to a plug.

[0038] 8. The bottom cover 7 also has a protruding structure 72 that protrudes downward to cooperate with and fix the housing, so as to facilitate the installation and fixation of the battery holder 100 on the housing, avoiding the use of additional fixing components, thereby reducing production costs.
