[0002] The terminal is a kind of circuit conduction element, is widely used in the product between cable and electric appliance, and is one of the most important connecting components on new energy electric vehicle. When connecting in later period, the terminal connects cable at one end, and the other end is connected with the connecting terminal on electric appliance to realize the electrical connection of electric appliance, so the whole terminal adopts conductive material, in order to realize insulation, it needs to be inserted into the terminal mounting groove of insulating nylon shell.

[0003] But the terminal of the prior art, such as patent application No. 202321936871.5, adopts clamping block to be clamped in the terminal mounting groove of nylon shell, but the structure has the following problems in use process: 1, when installing the terminal, the clamping block needs to be deformed in the center direction of the shell first, then the whole terminal can be inserted into the terminal mounting groove of nylon shell, but considering that the clamping block is too short, when installing, it is often caused that the clamping block is clamped in the center through slot of shell due to excessive force, and cannot be reset, finally often leads to the problem that the terminal cannot be limited after being inserted into the terminal mounting groove of nylon shell, and is easy to fall off from the terminal mounting groove in later period. At the same time, considering that the shell is used for avoiding the clamping block, the corresponding position adopts notch setting, which leads to that the overall strength of the position is not enough, and finally leads to the problem of low component strength.

[0004] In summary, the terminal of the prior art still has the problems of low overall strength and easy to separate from nylon shell when installing, which need to be improved. UTILITY MODEL CONTENTS

[0007] As preferred, to further realize the limiting effect of limit spring pressing position, a limiting convex point is arranged on the square recess relative to the end of limit spring away from the connection of base, for limiting the inclined end of limit spring.

[0008] As preferred, the wiring part includes cable wrapping sheet and wire core wrapping sheet, and the cross section of cable wrapping sheet and wire core wrapping sheet is "U" shaped structure.

[0009] As preferred, to further improve the strength of the whole, side edge reinforcing rib one is arranged between cable wrapping sheet and wire core wrapping sheet, triangular reinforcing rib is arranged on the inner side of side edge reinforcing rib one, side edge reinforcing rib two is arranged between wire core wrapping sheet and plug-in ear, and the size of the connection between side edge reinforcing rib two and wire core wrapping sheet is greater than the size of the connection between side edge reinforcing rib two and plug-in ear, and side edge reinforcing rib one, triangular reinforcing rib, side edge reinforcing rib two, wiring part, plug-in ear and base are integrally formed.

[0010] As preferred, to further improve the strength of the whole, more than one reinforcing rib three is arranged on the inner side of wire core wrapping sheet, and reinforcing rib three extends along the cross section shape of wire core wrapping sheet.

[0011] As preferred, to further limit limit spring and avoid turning to the front face of base through long hole after pressing, finally unable to limit the whole connecting terminal, the width of limit spring is greater than the width of long hole.

[0012] As preferred, to further fix and limit later cable, two hooks are mirror image distributed on the inner side of opening of cable wrapping sheet.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: In this structure, since the limiting spring 7 is located on the outer side of the back of the base, and one end of the limiting spring is raised, and the raised end is longer than the square inner groove, the limiting spring is affected by the limiting on the back of the base when it is squeezed later. The limiting spring will not flip from the elongated through hole to the front of the base, and it will not be limited and stuck, preventing it from rebounding, until the entire connecting terminal can be inserted into the corresponding terminal mounting slot of the nylon shell. After the external force disappears, the limiting spring will reset and be stuck in the corresponding terminal mounting slot of the nylon shell under the action of elasticity, thus preventing it from falling off. Therefore, this structure can further improve the overall strength of the terminal and make it less likely to detach from the nylon shell after installation. Attached Figure Description
