Description

Technical Field

[0001] This utility model relates to the field of generator battery cable connection terminal technology, and in particular to a generator corrosion-resistant battery cable connection terminal. Background Technology

[0002] The generator is the main power source for electrical equipment. During normal operation, the generator supplies power to other electrical equipment except the starter motor and charges the battery.

[0003] A battery cable is provided between the generator and the battery. The ends of the battery cable are pre-connected with copper terminals. The terminals are equipped with sleeves and wires. The battery cable is sleeved onto the wires and fused together for fixation. Terminal connectors are pre-installed on both the generator and the battery. The terminal connectors are equipped with screw grooves.

[0004] Currently, the outer surface of the connecting terminals on the battery cable between the generator and the battery is prone to corrosion, and the connection between the connecting terminals and the top of the terminal connector is easily subjected to impact, which greatly reduces the corrosion resistance of the outer surface of the connecting terminals on the battery cable between the generator and the battery, as well as the impact resistance of the top of the terminal connector.

[0005] In addition, the connection terminals on the battery cable between the existing generator and the battery are prone to horizontal rotation if they are bumped, which can lead to loosening and instability of the connection terminals.

[0006] Therefore, we designed a connection terminal on the battery cable between the generator and the battery to meet the needs of practical applications. Utility Model Content

[0007] The purpose of this utility model is to address the aforementioned shortcomings in the existing technology by proposing a generator corrosion-resistant battery cable connection terminal.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: A corrosion-resistant battery cable connection terminal for a generator is designed, comprising a connection terminal with a sleeve, a terminal block and a connector, a bearing seat on the connector, a battery body above and below the connection terminal, a wire groove on the battery body, a terminal connector inside the wire groove, a threaded groove on the terminal connector, a bolt threaded into the threaded groove, a bolt cap on the bolt, and a corrosion-resistant coating on the connection terminal. The groove is provided with a limiting screw groove, the bearing seat is provided with a bearing, the bearing is provided with a connecting shaft, the connecting shaft is provided with a top guard plate, and the top guard plate is provided with a side guard and a nut screw; The cable groove is provided with a positioning groove, and the connecting terminal is provided with a positioning post.

[0009] In detail, the corrosion-resistant coating is a nickel-plated structure with a thickness of 20 to 25 micrometers, and the corrosion-resistant coating is uniformly applied along the surface of the connecting terminal, wiring terminal, sleeve, positioning post, connector, and bearing seat.

[0010] In detail, the bearing is embedded in the bearing housing and fixedly connected to the connecting shaft, and the lower end face of the top guard plate has a gap with the bearing housing and the connecting terminal.

[0011] In detail, the top guard plate is a rectangular structure with a gap between it and the bolt head, and the side guard is an arc-shaped cover structure located at the bottom of the top guard plate.

[0012] In detail, the grommets are threadedly connected to the side guards, and the limiting screw groove is opened on the side wall of the groove and is horizontally aligned with the grommets.

[0013] In detail, the positioning groove is opened at the bottom of the wire groove, and the positioning post is located at the lower end of the connecting terminal. The positioning groove and the positioning post are a set, and there are a total of three sets arranged in a circle.

[0014] In detail, the connecting terminal is fitted onto the terminal connector through a sleeve, and the top surface of the connecting terminal is flush with the top surface of the terminal connector and tightly fits against the lower end surface of the bolt head.

[0015] The design scheme proposed in this utility model has the following beneficial effects in application: 1. This utility model comprehensively improves the corrosion resistance of the outer wall of the overall structure of the connecting terminal by coating the entire outer wall with a corrosion-resistant coating structure, and by setting a rotating top guard plate, side guards and nut screw structure on the connecting terminal. It also effectively protects the top of the connection part between the connecting terminal and the terminal connector, greatly improving the corrosion resistance of the outer surface of the connecting terminal on the battery cable between the generator and the battery and the anti-collision performance of the top of the terminal connector.

[0016] 2. This utility model arranges three positioning posts in a circular pattern on the connecting terminal and sets matching positioning grooves on the wire groove. After the connecting terminal is sleeved and threaded, the positioning posts are stably inserted into the wire groove. If the terminal is hit, it effectively avoids horizontal rotation of the connecting terminal, thereby improving the anti-loosening stability of the connecting terminal. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-6 A generator corrosion-resistant battery cable connection terminal includes a connection terminal 3, a sleeve 31 on the connection terminal 3, a terminal 30 and a connector 4 on the connection terminal 3, a bearing seat 41 on the connector 4, a battery body 1 above and below the connection terminal 3, a wire groove 11 on the battery body 1, a terminal connector 2 in the wire groove 11, a screw groove 21 on the terminal connector 2, a bolt 5 threadedly connected in the screw groove 21, a bolt cap 51 on the bolt 5, and a corrosion-resistant coating 8 on the connection terminal 3. The wire groove 11 is provided with a limiting screw groove 12, the bearing seat 41 is provided with a bearing 42, the bearing 42 is provided with a connecting shaft 61, the connecting shaft 61 is provided with a top guard plate 6, the top guard plate 6 is provided with a side guard 62 and a machine screw 7. The cable tray 11 is provided with a positioning groove 13, and the connecting terminal 3 is provided with a positioning post 32. The connector 4, bearing seat 41, top guard plate 6, connector shaft 61, side guard 62, nut screw 7 and positioning post 32 described in this patent are all made of plastic steel, which is insulating, durable and lightweight. They are firmly bonded to each other by special epoxy resin glue, and have the characteristics of corrosion resistance, aging resistance and environmental impact resistance.

[0021] Connection terminal 3 is the connection terminal on the battery cable between the generator and the battery. In existing technology, some existing structures are not marked, so there is no need to elaborate.

[0022] It should be further noted that the corrosion-resistant coating 8 is a nickel-plated structure with a thickness of 20 to 25 micrometers. The corrosion-resistant coating 8 is uniformly applied along the surfaces of the connecting terminal 3, wiring terminal 30, sleeve 31, positioning post 32, connector 4, and bearing seat 41. The nickel-plated structure has excellent stability and can resist acid and alkali corrosion. At the same time, it can also provide excellent polishing performance and maintain gloss.

[0023] It should be further explained that the bearing 42 is embedded in the bearing housing 41 and fixedly sleeved with the connecting shaft 61. The lower end face of the top guard plate 6 has a gap with the bearing housing 41 and the terminal 30, so as to realize the stable rotation of the axis of the top guard plate 6 and prevent it from slipping out of the bearing housing 41.

[0024] It should be further noted that the top guard plate 6 has a rectangular structure and a gap with the bolt cap 51. The top guard plate 6 and the side guard 62 are made of transparent PVC material, which is insulating and impact resistant, and also has excellent corrosion resistance.

[0025] The side cover 62 is an arc-shaped cover structure located at the bottom of the top cover 6. When the top cover 6 is rotated, the arc-shaped side cover 62 avoids colliding with the connection terminal 3.

[0026] It should be further explained that the grommet 7 is threadedly connected to the side cover 62, and the limiting screw groove 12 is opened on the side wall of the wire groove 11 and is horizontally aligned with the grommet 7. The right end of the grommet 7 has a pre-set internal hexagonal groove, and the grommet 7 can be easily rotated and locked into the limiting screw groove 12 by using an internal hexagonal wrench.

[0027] It should be further explained that the positioning groove 13 is opened at the bottom of the wire groove 11, and the positioning post 32 is located at the lower end of the connecting terminal 3. The positioning groove 13 and the positioning post 32 are a group, and there are three groups arranged in a circle. When the positioning post 32 is vertically positioned and inserted into the matching positioning groove 13, if the terminal 30 is hit, it can effectively prevent the connecting terminal 3 from rotating horizontally, thereby improving the anti-loosening stability of the connecting terminal 3.

[0028] It should be further explained that the connecting terminal 3 is fitted onto the terminal connector 2 through the sleeve 31. The top surface of the connecting terminal 3 is flush with the top surface of the terminal connector 2 and tightly fits the lower end surface of the bolt cap 51. The front view cross section of the bolt cap 51 is a trapezoidal structure, and the size of its lower end surface is not smaller than the sleeve 31, so as to effectively press the upper end surface of the connecting terminal 3 and prevent it from falling off.

[0029] Operating procedure: During installation, first, fit the connecting terminal 3 onto the terminal connector 2 through the sleeve 31, while ensuring that the lower end face of the positioning post 32 is flush with the bottom end face of the inner groove of the wire trough 11. (Refer to...) Figure 6 Next, rotate the top cover plate 6 into the wire groove 11, and then screw the bolt 5 into the threaded groove 21. After the lower end face of the bolt head 51 is tightly fitted with the upper end face of the connecting terminal 3, the connecting terminal 3 can be installed. Next, refer to Figure 3 and Figure 4 At this point, the nut screw 7 is aligned with the threaded groove 12. Take the matching Allen wrench and insert it into the preset Allen groove on the right end of the nut screw 7. Then, turn the Allen wrench clockwise to rotate the nut screw 7 clockwise and lock it into the threaded groove 12, thus locking the top guard plate 6 in place. At this time, the top protective plate 6 has fully protected the top surface of the connecting terminal 3. At the same time, by coating the outer wall of the overall structure of the connecting terminal 3 with a corrosion-resistant coating 8, not only is the corrosion resistance of the outer wall of the overall structure of the connecting terminal 3 improved, but the top of the connection between the connecting terminal 3 and the terminal connector 2 is also effectively protected. This greatly improves the corrosion resistance of the outer surface of the connecting terminal 3 on the battery cable between the generator and the battery, as well as the impact resistance of the top of the terminal connector 2.

[0030] In addition, after the connecting terminal 3 is sleeved and threaded, the operating bolt cap 51 presses down on the connecting terminal 3. At this time, each positioning post 32 will be vertically positioned and inserted into the matching positioning groove 13. If the terminal 30 is hit, it can effectively prevent the connecting terminal 3 from rotating horizontally, thereby improving the anti-loosening stability of the connecting terminal 3. The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
