Description

Binding post

Technical field

The utility model relates to field of connectors, and more particularly, it relates to a kind of binding post.

Background technology

Binding post is a kind of parts that electronic engineering technical staff often contacts.Its effect is very simple: be blocked in circuit between place or isolated obstructed circuit, erect the bridge of communication, thus make current flowing, make the function that circuit realiration is predetermined.Binding post links together for section power line or data wire and carries out electric power or electronic data transfer.Binding post generally coordinates spacing shell work, and binding post is placed in spacing shell.

Existing binding post all adopts the hangnail of outwardly convex disposed thereon to avoid the binding post be arranged in spacing shell to drop with spacing shell clamping.Such as application number is that the Chinese patent of CN201420472095.2 discloses a kind of binding post, comprise contact pin mouth and be arranged on the elastic contact element in contact pin mouth, contact pin mouth comprises upper surface, lower surface and two sides, contact pin mouth is rectangular on cross section, lower surface is connected with elastic contact element, upper surface comprises the first shell fragment and the second shell fragment, first shell fragment and the second shell fragment are connected with two sides and fold inward respectively, the opposite side of the corresponding elastic contact element of upper surface is provided with the projection of spacing shell of conflicting, at the first shell fragment, second shell fragment, the deformation space of the first shell fragment and the second shell fragment deformation is formed between projection and spacing shell.Although the barb structure on it arranges the connectivity robustness that can ensure binding post and spacing shell, but this vibrational power flow is dismantling the very inconvenience of binding post and spacing shell, and arranging of hangnail easily causes hangnail to be out of shape the binding post causing needing more to renew that even ruptures when dismantling, affect the useful life of binding post largely.

Utility model content

For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of binding post, and it is that solving the spacing shell of fractionation shines into pair of wire connection terminals during binding post the problem damaged.

For achieving the above object, the utility model provides following technical scheme: a kind of binding post, comprise contact pin mouth and be arranged on the elastic contact element in contact pin mouth, contact pin mouth comprises upper surface, lower surface and two sides, described lower surface is connected with elastic contact element, on described lower surface, corresponding elastic contact element position is provided with opening, and described elastic contact element is arranged in bending, and described elastic contact element two ends are connected with opening both sides respectively.

By adopting technique scheme, by arranging an opening in the below of elastic contact element, being arranged by opening and only needing the corresponding clamping corresponding projection being set and can realizing between binding post and spacing shell on spacing shell.

The utility model is set to further: described elastic contact element is wholely set near one end of contact pin mouth and lower surface, and described elastic contact element abuts with lower surface away from one end of contact pin mouth.

By adopting technique scheme, the vibrational power flow being arranged to by elastic contact element fix one end activity in one end can insert contact pin when contacting with elastic contact element in contact pin mouth, contact pin is avoided to extrude elastic contact element and fixedly cause elastic contact element to be out of shape due to elastic contact element two ends, the useful life of improving binding post useful life of raising elastic contact element.

The utility model is set to further: described elastic contact element is < shape, and the angle of described elastic contact element is obtuse angle.

By adopting technique scheme, < shape structure is more prone to produce, and obtuse angle is arranged avoids elastic contact element bend relief too high, in use easily deforms.

The utility model is set to further: the width of described opening equals the width of lower surface.

By adopting technique scheme, reduce the production material of binding post, cost-saving.

In sum, it is simple that the utility model binding post has structure, splits spacing shell and can not pair of wire connection terminals shine into and damage and the advantage of long service life with during binding post.

Embodiment

Referring to figs. 1 through Fig. 3, the utility model binding post is described further.

Be a kind of execution mode of the utility model binding post as shown in Figure 1 to Figure 3, it elastic contact element 2 comprising contact pin mouth 1 and be arranged in contact pin mouth 1, contact pin mouth 1 comprises upper surface 4, lower surface 3 and two sides 5, contact pin mouth 1 is rectangular on cross section, described upper surface 4 comprises the first shell fragment 41 and the second shell fragment 42, first shell fragment 41 is connected with two sides 5 and fold inward respectively with the second shell fragment 42.

As shown in Figure 1, described lower surface 3 is connected with elastic contact element 2, and on described lower surface 3, corresponding elastic contact element 2 position is provided with opening 31, and described elastic contact element 2 is arranged in bending, and described elastic contact element 2 two ends are connected with opening 31 both sides respectively.By arranging an opening 31 in the below of elastic contact element 2, being arranged by opening 31 and only needing the corresponding clamping corresponding projection being set and can realizing between binding post and spacing shell on spacing shell.

Further, described elastic contact element 2 is wholely set near one end of contact pin mouth 1 and lower surface 3, and described elastic contact element 2 abuts with lower surface 3 away from one end of contact pin mouth 1.The vibrational power flow being arranged to by elastic contact element 2 fix one end activity in one end can insert contact pin when contacting with elastic contact element 2 in contact pin mouth 1, contact pin is avoided to extrude elastic contact element 2 and fixedly cause elastic contact element 2 to be out of shape due to elastic contact element 2 two ends, the useful life of improving binding post useful life of raising elastic contact element 2.

In addition, described elastic contact element 2 is in < shape, and the angle of described elastic contact element 2 is obtuse angle.

By adopting technique scheme, < shape structure is more prone to produce, and obtuse angle is arranged avoids elastic contact element 2 bend relief too high, in use easily deforms.The width of described opening 31 equals the width of lower surface 3, reduces the production material of binding post, cost-saving.

The above is only preferred implementation of the present utility model, protection range of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection range of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection range of the present utility model.
