Abstract

The utility model discloses a crystal head plug, which comprises a crystal head (1) installed at the end head of a cable (3), and an elastic piece (2) is fixed on the crystal head (1). The crystal head plug further comprises a sleeve body (4), and a pit (5) for containing the crystal head (1) is arranged in the sleeve body (4). The crystal head plug can prevent a metal pin from moisture, rust and ash when the crystal head (1) is not inserted in a connector.

Description

The crystal head plug

Technical field

The utility model relates to the comprehensive wiring field, specifically is a kind of crystal head plug.

Background technology

Be equipped with the crystal head plug on telephone wire and the netting twine, wherein, telephone wire is a RJ11 type plug, and netting twine is a RJ45 type plug, and the crystal head plug inserts in telephone interface or the network interface card interface and uses.The crystal head plug of prior art comprises the crystal head that is installed in cable knob, is fixed with a shell fragment on the crystal head, and when the crystal head plug was inserted interface, shell fragment utilized elasticity that crystal head is stuck in the interface.

There is following defective in the crystal head plug of prior art: because all the metal PIN pins on the crystal head all are exposed; If do not use the crystal head plug for a long time; Promptly the crystal head plug is not inserted interface; Exposed metal PIN pin just possibly made moist by the corrosion of malaria or rainwater and get rusty, and perhaps is stained with ash, finally causes metal PIN pin loose contact even can't use; And, wiring or when transporting, the shell fragment of crystal head is hooked on other article such as the cable easily, use very inconvenient, undue force even maybe be with the shell fragment dislocated down-warping.

Summary of the invention

The technical problem that the utility model will solve is to provide a kind of metal PIN pin that when crystal head does not insert interface, prevents to make moist, get rusty, be stained with the crystal head plug of ash.

The technical solution of the utility model is, a kind of crystal head plug is provided, and it comprises the crystal head that is installed in cable knob, is fixed with a shell fragment on the crystal head, and it also comprises a body, is provided with the pit of ccontaining crystal head in the body.

The crystal head plug of above structure compared with prior art has the following advantages:

Because it also comprises a body, is provided with the pit of ccontaining crystal head in the body, like this; When the crystal head plug does not use; Crystal head directly is linked in the body,, isolates with airborne moisture and dust so the cover physical efficiency protects the metal PIN pin on the crystal head; Prevent that metal PIN pin from making moist, getting rusty and be stained with ash, avoid the loose contact of PIN pin and the situation that can't use takes place; And when need using the crystal head plug, crystal head extracted out from body insert interface again and get final product.

As improvement, the cross sectional shape of pit is a convex shape, and the such shape and the shape of crystal head are more identical, makes crystal head cooperate with body closely, and the water proof and dust proof effect is better.

As improving, it also comprises the bluff piece of flexible material again, and an end of bluff piece is fixed on the body; The free end of bluff piece is fixed with the collar that is used for the fit cable, like this, the collar is linked on the cable; The body and the crystal head plug rational and effective that can will be connected with the collar link together, and prevent the body loss, can make things convenient for when not using the crystal head plug and need entangle crystal head with body and find body rapidly; And more crucial be that the bluff piece of elastomeric material can block protection outside the shell fragment of crystal head, prevents that shell fragment is hooked into other object; Stop the situation that shell fragment is hung up; And the convenient bending of the bluff piece of flexible material, the cable of at utmost fitting is to shell fragment protection better effects and if can not hinder the use of cable.

As also improving, the internal diameter of the collar is slightly larger than the external diameter of cable, like this, the collar can be on cable slide relative, can be not stuck on cable, the cable of fitting greatly, better protection shell fragment.

As further improvement, bluff piece is fixed on a side of the chamber of the ccontaining shell fragment of body, and like this, bluff piece is limited in a side of the shell fragment of crystal head, better hides shell fragment, to the protection better effects if of shell fragment.

As further improving, the bluff piece of flexible material is meant the bluff piece of PE material again, and the bluff piece elasticity and the ductility of this kind material are best, and is the most desirable to the protection effect of shell fragment.

Embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.

Like Fig. 1, Fig. 2, shown in Figure 3, the utility model crystal head plug, it comprises the bluff piece 6 of the crystal head 1 that is installed in cable 3 terminations, body 4 and flexible material.Be fixed with a shell fragment 2 on the crystal head 1.The cross sectional shape that is provided with ccontaining crystal head 1 in the body 4 is the pit 5 of convex shape.The bluff piece 6 of the bluff piece 6 preferred PE materials of flexible material.One end of bluff piece 6 is fixed on the body 4, and in particular, an end of bluff piece 6 is fixed on a side of the chamber of body 4 ccontaining shell fragments 2.The free end of bluff piece 6 is fixed with the collar 7 that is used for fit cable 3.The internal diameter of the collar 7 is slightly larger than the external diameter of cable 3.
