Abstract
Description
Technical Field
[0001] The utility model relates to an electric connector tail accessory, in particular to an electric connector tail accessory which is convenient for adjusting the outlet direction. Background Art
[0002] In the electrical industry, electrical connectors often need to be used with tail accessories for clamping cables (or wires), which are generally called electrical connector tail accessories. When in use, the electrical connector tail accessories are mechanically connected to the electrical connector (generally through threaded connection), and the cables (or wires) pass through the electrical connector tail accessories and are electrically connected to the electrical connector (generally by plugging or welding). The electrical connector tail accessories have the function of preventing the cables (or wires) from being pulled apart and failing due to external forces.
[0003] The basic structure of the tail accessories of an electrical connector includes interconnected tubular adapter sleeves and clamping parts for clamping cables. According to the different angular relationships between the direction in which the cable is led out of the clamping parts, i.e., the direction in which the cable is led out and the center line of the adapter sleeve, the traditional tail accessories of an electrical connector include two types: straight tail accessories and curved tail accessories. The former refers to the tail accessories of an electrical connector in which the line direction is consistent with the center line direction of the adapter sleeve, and the latter refers to the tail accessories of an electrical connector in which there is a certain angle between the line direction and the center line of the adapter sleeve, and the angle is generally 90°, but can also be other angles such as 45° or 135°.
[0004] The tail accessories of traditional electrical connectors have the following defects: no matter whether it is a straight tail accessory or a curved tail accessory, the wire outlet direction is fixed. When users have different wire outlet directions, they can only purchase tail accessories with different wire outlet directions respectively. On the one hand, it causes inconvenience in application, and on the other hand, it usually causes the problem of some tail accessories being idle and wasted; at the same time, if the wire outlet direction of the use occasion is relatively special, customization is required, which will extend the purchase time and increase the purchase cost, and because the demand for customized products with special needs is very small and cannot form large-scale production, many manufacturers are unwilling to provide this customization service, which will result in users not being able to buy suitable tail accessories. Users can only choose similar products, which leads to reduced reliability of related electrical products and seriously restricts the design method of circuit systems; at the same time, it is also not conducive to manufacturers' mass production to reduce costs.
