Abstract
The invention relates to a connecting device for an underground cable distribution box. The connecting device is used for connecting and sealing adjacent connector portions of the distribution box and is characterized by comprising an upper pressing plate, a lower pressing plate, an upper silicone sealing pad and a lower silicone sealing pad; the upper pressing plate and the lower pressing plate are symmetrically arranged and are both formed by connecting side wings inclined outwards to the two ends of a main pressing plate arranged horizontally, and at least one connecting lug plate with the outer end inclined upwards is fixed to the outer surface of each side wing; the upper silicone sealing pad and the lower silicone sealing pad are of the same structure and are in a [ shape capable of being attached to the inner surfaces of the upper pressing plate and the lower pressing plate. The connecting device has the advantages that a small included angle exists between the connecting lug plates and the horizontal plane because the connecting lug plates are perpendicular to the side wings, the side wings of the upper pressing plate and the lower pressing pate are pressed inwards through the included angle when the upper pressing plate and the lower pressing plate are fixed in a bolted connection mode, and then the side edges of the upper silicone sealing pad and the lower silicone sealing pad are tightly attached to the connector surfaces of the distribution box; meanwhile, the ends of the side edges of the upper silicone sealing pad and the lower silicone sealing pad can be tightly attached, and therefore the sealing effect is ensured.
Description
Technical field
The present invention relates to a kind of connector, particularly a kind of underground cables junction box connector.
Background technology
Junction box is a kind of industrial connector.Junction box is that a power supply of access or data are passed through point stream translation, can export the equipment of many electric currents or data-signal.Junction box can be arranged in the narrow spaces such as underground, crane span structure, casing, pipeline, cable trough, does not take effective usable floor area of building, easy for installation, does not need to block leader cable.
Current known connector of distributing box adopts structure example such as number of patent application 201520242388.6 to disclose the high-effective water-proof connector of a kind of waterproof ground wiring equipment, it comprises: the integral, flexible gum cover being sleeved on adjacent wire casing interface portion position, the outer surface up and down of integral, flexible gum cover gives up the convex tendon that friendly multiple tracks forms annular, the upper and lower sides coated upper and lower pressing plate respectively of integral, flexible gum cover, upper and lower pressing plate adopts symmetrically arranged C shape structure, utilizes bolt that upper and lower pressing plate is connected locking.
In said structure, adopt the form of overall gum cover and supporting upper and lower pressing plate, make sealing property excellent, water resistance is reliable.But also there is certain defect in it: because gum cover adopts overall structure, when it is installed, after needing that gum cover one end is sleeved on a junction box port, the other end is dug, adopt and install, trouble is installed, simultaneously, upper and lower pressing plate connect time, its only have upper and lower to coupling mechanism force, for gum cover side cannot give and enough coupling mechanism forces, therefore, the sealing effectiveness of side is poor.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of good sealing effect, underground cables junction box connector easy for installation.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of underground cables junction box connector, connection for adjacent junction box interface position seals, its innovative point is: comprise the identical and symmetrically arranged upper and lower pressing plate of a pair structure, the main pressing plate two ends that described upper and lower pressing plate is arranged by horizontal direction connect the flank tilted laterally and form, the angle that described main pressing plate and flank are formed is 96 ~ 98 °, the outer surface of described each flank is all fixed with the acclivitous connection otic placode at least one outer end, connects otic placode perpendicular to flank; The upper and lower silica gel sealing pad that a pair structure is identical, described upper and lower silica gel sealing pad is " ［ " the font can fitted with upper and lower pressing plate inner surface; The inner surface being close to junction box interface at upper and lower silica gel sealing pad is distributed with some roads sealing protrusion, and described seal convexity is parallel to junction box interface.
Preferably, described upper and lower pressing plate is provided with the reinforcement that some roads protrude outer surface.
Preferably, described upper and lower silica gel sealing pad is after embedding upper and lower pressing plate inner surface respectively, and the flank of upper and lower pressing plate is stretched out in its end.
The invention has the advantages that: in the present invention, the main pressing plate two ends that upper and lower pressing plate adopts horizontal direction to arrange connect the flank tilted laterally and form, vertical with flank and then make to be connected otic placode and horizontal plane and there is a less angle owing to connecting otic placode, when upper and lower pressing plate is bolted fixing, this angle is utilized to be compressed to the inside by the flank of upper and lower pressing plate, and then the side of upper and lower silica gel sealing pad is close to junction box interface surface, simultaneously, can fit tightly between the end of upper and lower silica gel sealing pad side, guarantee sealing effectiveness.
In addition, upper and lower silica gel sealing pad is after embedding upper and lower pressing plate inner surface respectively, and the flank of upper and lower pressing plate is stretched out in its end, guarantees that the end of upper and lower silica gel sealing pad fits tightly, and can not cause the interference of upper and lower pressing plate flank.

Embodiment
Fig. 1 shows the underground cables junction box connector construction of the embodiment of the present invention, and the connection for adjacent junction box interface position is close, and it comprises
A pair structure identical and symmetrically arranged top board 1, lower platen 2, as shown in Figure 2,3, main pressing plate 11 two ends that top board 1, lower platen 2 are arranged by horizontal direction connect the flank 12 tilted laterally and form, the included angle A that main pressing plate 11 and flank 12 are formed is 96 ~ 98 °, the outer surface of each flank 12 is all fixed with the acclivitous connection otic placode 13 at least one outer end, connect connecting hole 14 or U-shaped opening that otic placode 13 is arranged, connect otic placode 13 perpendicular to flank 12.
Upper silica gel sealing pad 3, lower silica gel sealing pad 4 that a pair structure is identical, upper silica gel sealing pad 3, lower silica gel sealing pad 4 are " ［ " the font that can fit tightly with top board 1, lower platen 2 inner surface; As shown in Figure 4,5, it specifically comprises the primary seal pad 31 that horizontal direction is arranged, and be arranged on the sealing flank 32 at primary seal pad 31 two ends, the sealing outer surface of flank 32 non-fully are perpendicular to primary seal pad 31, itself and primary seal pad 31 form an included angle B, the angular range of this included angle B at 94 ~ 96 °, and this included angle B to be less than included angle A comparatively reasonable, certainly, included angle B also can be made to equal included angle A.
