Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a kind of connector structure of a battery terminal, and more particularly, to a quick connector of a battery pillar terminal for connecting an electric wire to a metal terminal of a battery.

[0002]

[Prior art]

 Batteries are widely used in various fields such as automobiles, motorcycles, ships, electric vehicles, continuous power systems, and portable electric equipment. Generally, commercially available lead-acid batteries (Pb-Acid Battery) are divided into two types of positive and negative terminals, a columnar type and an L-type terminal, of which the columnar terminal has a relatively large capacity battery. L-shaped terminals are mainly used for batteries of relatively small capacity.

FIG. 1 is a perspective view in which two columnar terminals 2 and 3 are arranged on the upper surface of a main body of a well-known lead-acid battery 1. The two pillar-shaped terminals 2 and 3 of the battery 1 are arranged at diagonal positions on the upper surface of the battery, and serve as plus and minus pole output terminals of the battery.

In a battery manufacturing process, a paste formed by kneading lead oxide powder (Lead Oxide) and sulfuric acid (H ₂ SO ₄ ) is uniformly applied to a battery grid, and after a curing step, the grid is removed. Install in the battery case and extend the two terminals. After the assembly of the battery plates and battery cases is completed, all of them require a formation step and thus become commercial products. In the so-called formation, one wire is connected to each of the two terminals of the battery, and the paste on the plates in the battery is subjected to electrochemical conversion under appropriate control conditions such as battery, voltage, time, and acid specific gravity. As a result, the positive and negative poles of the battery are formed.

[0005] In the known art, in order to connect the terminal of the battery and the electric wire, generally, a metal sleeve ring (not shown) is inserted into and held by the columnar terminal, and the metal sleeve is further bolted. Tighten the ring to fix. In another known technique, the pillar-shaped terminals 2 and 3 are sandwiched by a crocodile clip 4 and two plus and minus electric wires 5 are connected to the pillar-shaped terminals 2 and 3 respectively.

In the battery formation step described above, in addition to connecting the battery terminals to the electric wires, in many cases (eg, charging, discharging, and measuring the battery), the connection of the electric wires is required.

[0007] However, in the technique of connecting electric wires using such a well-known metal sleeve ring, a considerable amount of work time is consumed for tightening bolts, and thus does not meet the actual requirements of the manufacturer. If the crocodile clip is used, the crocodile clip has sharp teeth and has a strong elastic clamping force, so that the metal surface of the battery terminal is easily damaged during the clamping operation. Battery manufacturers had the problem of easily forming defective products. Furthermore, when a current is applied to the electric wire, the current path is concentrated on the sharp tooth end portion of the crocodile clip, so that the conduction function is poor. In the operation area, the use of the crocodile clip can save a lot of work time compared to the traditional bolted articulation method, but it cannot reduce the work time effectively. However, battery manufacturers spent a large amount of manpower when performing battery formation work in the formation room due to the large number of batteries connected at one time. In addition, there was a risk that the operator could touch the conductive part of the crocodile clip when performing the clamping work with this crocodile clip, which had a drawback in terms of safety.

For this reason, if there is a structure of a quick connector adapted to be used for a pillar-shaped battery terminal, it has considerable industrial utility in the battery industry.

[0009]

[Problem to be Solved by the Invention] The main object of the present invention is to provide a kind of quick connector that can quickly wire an electric wire to a battery pillar-shaped terminal, and operate the quick connector to carry out the work of bridging. When performing this, the connection between the electric wire and the battery pillar-shaped terminal can be completed quickly by a simple fitting operation, so that the operation time of the operator can be greatly reduced.

[0010] Another object of the present invention is to provide a kind of battery post terminal connector structure having good conductive effect, and when the connector is mounted on the battery post terminal, the annular contact surface of the connector is provided. To effectively and tightly contact the metal part of the battery post and to achieve a good conduction effect between the battery post and the wire.

Another object of the present invention is to provide a battery post terminal connector structure which does not damage the battery post terminal surface during connection of electric wires, and the terminal contact surface of this connector has a sharp tooth end. Therefore, it is possible to achieve a good conductive effect and to prevent the problem of damaging the surface of the pillar-shaped terminal.

Another object of the present invention is to provide a battery pole terminal connector structure having a relatively high electrical safety, and when an electric connection operation is performed by using this connector, an operator can use a conductive part. Can prevent accidental touching, and can effectively prevent arcing during erection, thus effectively resulting in poor contact between the sharp tooth end of the traditional crocodile clip and the danger caused by the arc or the termination of the terminal. The goal is to prevent damage.
