Embodiment

It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the utility model can To be mutually combined.

Describe the utility model in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

Embodiment one

The utility model is related to a kind of binding post, and it includes terminal body, and the terminal body, which has, is formed with connecting hole Flat part, the transition part that is connected with flat part of one end, and relative to flat part, be connected to the pincers pipe of the transition part other end Portion, multiple tooth engageds are correspondingly arranged in two opposite ends of pincers pipe portion, and the tooth engaged at two ends can be stung with the crimping of pincers pipe portion Together in together.

This binding post, can be in pincers pipe portion and conductor compression jointing by setting multiple tooth engageds in two opposite ends of pincers pipe portion When, crimping stress is uniformly distributed, wire is damaged so that crimping stress can be avoided excessive, meanwhile, the setting of tooth engaged also may be used Ensure the pulling capacity between binding post and wire so that fully contact between the two, and there can be preferable bonding strength.

Based on design as above thought, a kind of example arrangement of the binding post of the present embodiment middle institute as shown in Figure 1 to Figure 4 Show, wherein, the terminal body being made up of pincers pipe portion 1, transition part 2 and flat part 3 can integrally be formed by flat board bending, and particularly The terminal body can be made up of copper flat board, can make it have appropriate hardness, and fastening when being conducive to using.When So, except being made of copper, terminal body other conducting metals can also be made up of aluminium, stainless steel etc..

Pincers pipe portion 1 in the present embodiment is specially the " u "-shaped structure positioned at terminal body one end, and foregoing tooth engaged 11 is Two opposite ends of " u "-shaped structure are formed at, and to ensure the fastness of occlusion, the tooth engaged 11 at two ends also sets at least to two It is right.In use, the tooth engaged 11 at two ends wire with clamp pipe portion 1 crimp when be snapped at together with, and by conductor compression jointing in pincers pipe portion 1 It is interior, and the pincers pipe portion 1 of " u "-shaped structure is not only convenient for the shaping of two ends tooth engaged 11, while it can also be beneficial to during crimping Occlusion between two ends tooth engaged 11.
