Abstract

The utility model discloses a dustproof waterproof cable comprising a guide line and first and second connectors arranged on two ends; the first connector is externally connected with a dustproof cover, and a waterproof sealing ring is arranged around the dustproof cover plugged in the first connector; the waterproof sealing ring tightly abuts against an attach surface between the dustproof cover and the first connector, thereby providing effective dustproof and waterproof effects; by employing the waterproof and dustproof functions, an interface position between the cable and the equipment can prevent water inflow or dust inflow, thereby better protecting the equipment and the cable, ensuring connection reliability, and prolonging service life.

Description

A kind of dustproof and waterproof cable

Technical field

The utility model relates to cable art, refers in particular to a kind of dustproof and waterproof cable.

Background technology

In outdoor environment, have a large amount of dust and rainwater, or also have dust, water etc. in some industrial premises, under the adverse circumstances of the many dirt of this humidity, the interface between equipment and wire has strict water proof and dust proof requirement.In current cable, poor sealing between its connector and equipment, causes connecting position easily to be intake, and is subject to dust pollution serious, not only shortens useful life, but also affects the reliability that equipment and wire join.

Utility model content

In view of this, the utility model is for the disappearance of prior art existence, and its main purpose is to provide a kind of dustproof and waterproof cable, without worrying water inlet and dust pollution, ensures that cable can reliably be connected with equipment.

For achieving the above object, the utility model adopts following technical scheme:

A kind of dustproof and waterproof cable, the first joint, the second joint that comprise wire and two ends, this first joint is externally connected with a dust cap, is provided with waterproof grommet in the periphery of dust cap, this dustproof capping plug is in the first joint, and this waterproof grommet pushes against in the binding face of dust cap and the first joint.

Preferably, described the first joint periphery is also provided with waterproof grommet.

Preferably, described the first joint periphery is provided with the clasp being connected on the service of connection devices.

Preferably, be coated with 3 power lines and 1 signal line in described wire, this power line and holding wire extend outside the second joint, and are packaged into terminal wafer at the free end of power line and holding wire with acrylic.

Preferably, the wire diameter of described power line is greater than the wire diameter of holding wire.

Preferably, described the first joint and the second joint are respectively with the one-body molded two ends that are connected in wire of PVC material.

The utility model compared with prior art has obvious advantage and beneficial effect, particularly, as shown from the above technical solution, owing at the first joint, dust cap being set outward, on this dust cap, there is waterproof grommet, thereby dust cap can clog the first joint, push against binding face each other with waterproof grommet, so just can reach effective dust and water protection effect, be particularly useful for the building site environment of outdoor environment or indoor many dirt humidity.

For more clearly setting forth architectural feature of the present utility model and effect, below in conjunction with accompanying drawing and specific embodiment, the utility model is elaborated.

Embodiment

Please refer to shown in Fig. 1,2, the concrete structure that it has demonstrated the preferred embodiment of the utility model, includes the first joint 20, second joint 30 at wire 10 and two ends.This first joint 20 and the second joint 30 are respectively with the one-body molded two ends that are connected in wire 10 of PVC material, adopt the integrated mode of production, and technique is simple, and production efficiency is high.

Wherein, as shown in Figure 3-4, outside this first joint 20, be connected with a dust cap 21, be provided with waterproof grommet 22 in the periphery of dust cap 21.When the first joint 20 does not use, this dust cap 21 is filled in the first joint 20, and this waterproof grommet 22 pushes against in the binding face of dust cap 21 and the first joint 20; When the first joint 20 uses, dust cap 21 is extracted, owing to having intercell connector 23 to join between dust cap 21 and the first joint 20, made dust cap 21 be difficult for losing.In addition, these the first joint 20 peripheries are also provided with waterproof grommet 22, and the first joint 20 peripheries are provided with the clasp 24 being connected on the service of connection devices, thereby in the time that the first joint 20 joins with equipment, clasp 24 can clamping equipment, is difficult for touching by mistake and departs from, and guarantees reliable connection.

As shown in Fig. 5-6, in described wire 10, be coated with 3 power lines, 11 and 1 signal line 12, the wire diameter of this power line 11 is greater than the wire diameter of holding wire 12, and the wire diameter of this power line 11 is 16AVG, and the wire diameter of this holding wire 12 is 24AVG.Distinguish for convenient, 3 power lines 11 select respectively the wire rod of black, brown, red three kinds of colors to represent, and holding wire 12 selects yellow wire rod to represent.This power line 11 and holding wire 12 extend outside the second joint 30, and are packaged into terminal wafer 13 at the free end of power line 11 and holding wire 12 with acrylic, and 4 pins 14 are set on terminal wafer 13, are convenient to join with equipment.As shown in Figure 1, before dispatching from the factory, because the wire 10 between first,

second joint

20,30 is grown (generally can stay 1.1～1.5 meters), therefore, when packaging, can overlapping the wire at middle part 10 rear bundle be got up with cable strap 15, neat and artistic.

When use, this terminal wafer 13 is connected with an equipment wherein, by the interface position of second joint 30 these equipment of locking, effectively slip-off preventing; And the second joint 30 is connected on the equipment of outdoor or wet environment, by its functions of waterproof and dustproof, without worrying the interface position water inlet of cable and equipment or entering dirt, thereby protect better equipment and cable, guarantee the unfailing performance of connection, increase the service life.

In sum, design focal point of the present utility model is, due at the outer dust cap 21 that arranges of the first joint 20, on this dust cap 21, there is waterproof grommet 22, thereby dust cap 21 can clog the first joint 20, push against binding face each other with waterproof grommet 22, so just can reach effective dust and water protection effect.

The above, it is only preferred embodiment of the present utility model, not technical scope of the present utility model is imposed any restrictions, therefore any trickle amendment, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of technical solutions of the utility model.
