Description

Technical Field

[0001] This utility model relates to the field of switches, specifically a battery terminal block. Background Technology

[0002] The battery terminal block, as the part of the battery switch that connects to the battery terminals, establishes the connection between the switch and the battery terminals. Existing battery terminal blocks have a socket at the bottom for insertion into the battery terminal. An adjusting bolt is mounted on the block, one end of which extends into the socket and is rotatably connected to a conductive plate. Rotating the adjusting bolt causes the conductive plate to clamp the battery terminal. The diameter of the socket is much larger than the diameter of the battery terminal. When connected to the battery terminal, this leaves more space, making the connection more prone to loosening or wobbling, resulting in an unstable connection. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-10 As shown, this embodiment discloses a battery terminal block, including:

[0032] The column 1 has a socket at its bottom, which matches the diameter of the battery terminal and is used to connect with the battery terminal.

[0033] Mounting groove 2 is formed on column 1 and communicates with the inner wall of the insertion hole to form a mounting part. For example... Figure 5 and Figure 10 As shown, the mounting groove 2 is an inverted L-shaped structure composed of horizontal and vertical grooves. The horizontal groove is located on the upper end face of the column 1, and the vertical groove is located on the inner wall of the insertion hole and is axially positioned. Figure 3 and Figure 8 As shown, the connection point between the vertical groove and the horizontal groove is the bent portion of the mounting groove. The opening of the bent portion is greater than the thickness of the conductive sheet 5 but less than the length of the horizontal portion of the conductive sheet 5. Figure 5 As shown, this design allows the conductive sheet 5 to slide horizontally without excessively sliding and falling out of the mounting groove 2. Compared to existing methods where the conductive sheet is inserted into the socket through the bottom opening (since the conductive sheet is inserted directly into the socket from the bottom opening, it is an independent component, and its position needs to be fixed when connected to the adjusting bolt, making installation inconvenient), the method in this embodiment is more convenient for installing the conductive sheet 5. The conductive sheet 5 is directly located in the mounting groove, preventing any shaking, and can directly contact the adjusting bolt 4.

[0034] The conductive piece 5 has an L-shaped structure consisting of a vertical part and a horizontal part. It can be inserted into the mounting groove 2 from the tail end of the horizontal groove (i.e., the bent part of the mounting groove) and make contact with the battery terminal. The vertical part is inserted into the vertical groove, and the horizontal part is located in the horizontal groove, thus completing the installation of the conductive piece 5. Specifically, as shown... Figure 5 , Figure 8 and Figure 10 As shown.

[0035] Cover plate 3 is detachably mounted on the upper end face of column 1 using screws, such as Figure 1 and Figure 7As shown, when the cover plate 3 is installed on the upper part of the column 1, it just contacts the upper surface of the horizontal part of the conductive sheet 5, and a contact connection can be formed between the cover plate 3 and the conductive sheet 5.

[0036] like Figure 1 , Figure 5 , Figure 6 and Figure 10 As shown, the area of ​​the cover plate 3 is close to the area of ​​the upper end face of the column. When the cover plate 3 is installed together with the column 1, it limits the horizontal part of the conductive sheet 5, so that the conductive sheet 5 can slide along the horizontal groove.

[0037] Adjusting bolt 4 is installed through the column 1, with one end extending into the mounting groove 2 to contact the conductive sheet 5, and the other end located outside the column 1, as shown in the details. Figure 5 and Figure 10 As shown, it is used to adjust the position of the conductive piece 5 inside the socket to ensure that the conductive piece can be connected to the battery terminal.

[0038] In this embodiment, the conductive sheet 5 is made of copper. The surface of copper is relatively smooth, and when the adjusting bolt 4 presses against the conductive sheet 5, the conductive sheet 5 can slide better in the horizontal direction.

[0039] Example 1

[0040] In this embodiment, as Figures 1-5 As shown, the column 1 has a square structure, suitable for square switches. At the bend and transition section of the conductive sheet 5, the column 1 has a threaded hole for installing the adjusting bolt 4. On the side of the conductive sheet 5 that does not contact the battery terminal, there is an adjusting hole matching the outer diameter of the adjusting bolt 4. When installing the conductive sheet 5, insert it into the placement groove 2, then insert the adjusting bolt 4 into the threaded hole and rotate it until it gradually engages with the adjusting hole, supporting the conductive sheet 5. Then, the cover plate 3 can be installed on the column 1, as detailed below. Figure 5 As shown, in this state, the adjusting bolt 4 supports the conductive plate 5. When the adjusting bolt 4 is adjusted inward, it can also press against the conductive plate 5 to clamp the battery terminal. A structure with a small bottom diameter and a large top diameter is formed between the two conductive plates 5. The adjusting bolt 4 contacts the upper part of the conductive plate 5. When the adjusting bolt is rotated, the conductive plate 5 can gradually clamp the battery terminal.

[0041] Example 2

[0042] like Figures 7-10As shown, the column 1 is approximately cylindrical in shape, suitable for cylindrical switches. The diameter of the socket is the same as or slightly larger than the diameter of the battery terminal (e.g., 1-2 mm larger, no specific limitation) to allow the socket to be inserted into the outside of the battery terminal. The bend of the conductive piece 5 is almost a right angle. The conductive piece 5 is inserted into the placement groove 2, with its bottom contacting the horizontal groove of the placement groove and its top contacting the bottom surface of the cover plate 3, allowing it to be stably installed in the placement groove. Figure 10 The structure shown is as follows: The two conductive plates 5 form a shape resembling the number "8" with a larger opening at the bottom and a smaller opening at the top. The top opening is slightly smaller than the diameter of the battery terminal. When the column 1 is inserted into the battery terminal, the larger bottom opening facilitates the insertion of the battery terminal. As the column 1 is pressed down, the battery terminal moves upward between the conductive plates 5 and gradually comes into contact with the conductive plates 5, completing the installation of the battery terminal.

[0043] In this application, a placement groove is opened in the socket of the column 1, and the conductive sheet 5 is placed in the placement groove. Compared with the existing conductive sheet installed in the socket (if the diameter of the socket is relatively large, more space will be left when connecting with the battery terminal, and the column is more likely to loosen or shake when connected, resulting in unstable connection), the diameter of the socket is smaller, and the installation with the battery terminal is more stable.

[0044] In a further embodiment, the number of the aforementioned mounting groove 2, conductive sheet 5, and adjusting bolts is not limited; it can be one, two, three, or four, depending on actual usage requirements. The more bolts present, the more clamping surfaces there are for the battery terminals, resulting in greater stability.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
