Referring to fig. 1 to 3, a connector head according to an embodiment of the first aspect of the present application is applied to curtain wall installation, and includes a base assembly, a connection assembly 200, a resilient member 300, and a circlip 400.

Wherein the base assembly has a mounting cavity 110, wherein one side of the mounting cavity 110 has an opening, and the other side of the mounting cavity 110 opposite the opening defines a bottom wall; one end of the connecting component 200 is provided with a ball head which passes through the opening and is arranged in the mounting cavity 110; the elastic piece 300 is arranged in the mounting cavity 110 and is positioned between the bottom wall and the ball head; the circlip 400 is disposed around the connection assembly 200, and the circlip 400 is disposed within the mounting cavity 110 between the opening and the ball head such that the circlip 400 is adapted to block the connection assembly 200 from being removed from the mounting cavity 110.

Referring to fig. 1 to 3, in the connector head according to the first aspect of the present application, by disposing the elastic member 300 and the circlip 400 on two sides of the ball head respectively, the ball head can be reliably limited, so that not only can the stress be uniform, but also the structural quality and stability can be ensured, meanwhile, the structure and the processing technology are simpler, the cost is saved, the connector head can be widely used, and in particular, the circlip 400 can prevent the ball head from falling out, if the circlip 400 is to be moved out of the mounting cavity 110, it must overcome the physical interference generated by the mounting cavity 110, so that the structure itself is very reliable.

In some embodiments, the base assembly may include a mount for retaining the circlip 400 such that the circlip 400 is securely fixed within the mounting cavity 110, but this may certainly result in some degree of structural complexity.

Thus, in some embodiments of the present application, an internal void 111 is formed within the mounting cavity 110, the internal void 111 being disposed adjacent to the opening, the internal void 111 being adapted to receive the circlip 400. It will be appreciated that, based on the elastic properties of the circlip 400, the circlip 400 may be fitted directly into the hollow 111 by extrusion to achieve a secure fit and recover size after placement in the hollow 111. It should be noted that, the circlip 400 can block the ball screw from coming out, if the circlip is to be moved out of the cavity, it must overcome the physical interference generated by the hollow groove, and for this reason, when the circlip 400 and the ball contact each other, it needs to overcome a lot of deformation, that is, it can come out of the cavity after generating a strong stress. Namely, the anti-falling effect of the application is very obvious.

Specifically, the circlip 400 is configured as a circlip, and on the basis that the material characteristics can be elastically deformed, the circlip is deformed through the assistance of structural characteristics, so that the circlip can be installed conveniently, and meanwhile, the anti-falling effect of the application is ensured.

It can be appreciated that by defining the dimensions of the guide groove 112 and the hollow groove 111, the split ring can be fitted into the hollow groove 111 within a proper elastic deformation range, while having an excellent anti-falling effect.

In some embodiments of the present application, the base assembly includes a mounting base 100, a sleeve 500, and a clamping plate 600, the mounting cavity 110 is formed on the mounting base 100, the clamping plate 600 is disposed on the mounting base 100, and the sleeve 500 is disposed between the mounting base 100 and the clamping plate 600 such that the mounting base 100, the sleeve 500, and the clamping plate 600 enclose a mounting area for mounting. It will be appreciated that the connector works by first drilling a hole in the glass, passing the mount 100 through a glass hole, which is spaced from the mount 100 by the shroud 500. The clamp plate 600 is then screwed on to clamp the glass against the large end of the mounting block 100 and secure it.

In some embodiments, a first spacer 710 is disposed between mount 100 and sleeve 500, and a second spacer 720 is disposed between clamp plate 600 and sleeve 500. The gasket ensures the stability of the overall structure among the mounting base 100, the pipe sleeve 500 and the clamping plate 600, and can reliably clamp glass.

It is understood that the connection assembly 200 may be provided with a nut, a sleeve, etc. for connection on the other end of the connection assembly 200 according to the use requirement. In some embodiments, the connection assembly 200 is configured as a ball-nose threaded rod, directly utilizing the threaded outer sidewall of the ball-nose threaded rod for connection installation, by reserving thread segments long enough to allow for adaptive adjustment of the manner of specific installation in the construction site.

It can be appreciated that the elastic member 300 is disposed in the mounting cavity 110 and between the bottom wall and the ball head, and the ball head abuts against the elastic member 300 to perform a good buffering function.

Specifically, the elastic member 300 is provided as a spring or a rubber gasket, and may be a structural member with similar functions such as a buffer layer, but considering that rubber is aged, the rubber gasket disposed at the bottom of the mounting seat 100 may be replaced with a spring, such as a wave spring, according to an application scenario, so as to obtain a more excellent service life.
