Detailed Description
In order to further understand the objects, structures, features and functions of the present invention, the following embodiments are described in detail.
Referring to fig. 1 to 3 and fig. 2 in combination, the invention provides a glue overflow structure design of a box body of a glue pouring type junction box, as shown in fig. 1, the box body of the junction box comprises a first end 1 and a second end 2 which are opposite, the first end 1 and the second end 2 are both in a semicircular structure, a cable connector is arranged in front of the first end 1, two side glue overflow grooves 11 are symmetrically arranged on two sides inside the first end 1, and an end glue overflow groove 21 is arranged in the center of an arc of the second end 2; the side glue overflow groove 11 comprises glue overflow groove plates 12 and side plates 13, a first U-shaped notch 14 is formed in the top end of each glue overflow groove plate 12, the glue overflow groove plates 12 of the two side glue overflow grooves 11 are arranged oppositely, the side plates 13 are perpendicular to the glue overflow groove plates 12, the end glue overflow groove 21 comprises an end glue overflow plate 22, and a second U-shaped notch 24 is formed in the top end of the end glue overflow plate 22.
The glue overflow groove structure is reasonably designed according to the overflow condition of glue at different positions in the glue pouring process. Glue is poured into from first end 1 during the encapsulating, because the flow velocity of glue is comparatively slow, and glue is easy to overflow to both sides because the speed that flows forward is too slow when constantly pouring into, consequently respectively sets up side on the both sides of first end 1 and overflows gluey groove 11, can play the effect of "flood discharge" to the glue that overflows in both sides. The excessive glue on the two sides enters the side glue overflow groove 11 along the U-shaped notch of the side glue overflow groove 11, so that the situation that the smooth assembly of the upper cover is influenced due to the fact that the glue is excessive and exceeds the set height is prevented. The glue flows forwards while being poured into the junction box until the second end 2 is filled; because glue constantly flows to the second section from first end 1 when encapsulating, the glue yield of first end 1 is generally greater than the glue yield of second end 2, when second end 2 was full, static waiting period, first end 1 unnecessary glue slowly flows to second end 2 and makes the interior glue evenly distributed of junction box, unnecessary glue can appear in the box body, unnecessary glue continues to flow forward, and overflow in the gluey groove 21 of U type breach inflow tip from tip excessive rubber plate 22, prevent that glue is too much, exceed the height of settlement, influence the smooth equipment of upper cover.
In one embodiment, as shown in fig. 2 and 3, the two top sides of the two first U-shaped notches 14 extend toward the center of the notch with first top blocking pieces 15; the two sides of the top end of the U-shaped notch of the end glue overflow plate 22 extend oppositely to the center of the notch to form a second top blocking piece 25. Because the surface of the glue is arc-shaped due to the tension action of the surface of the glue, when the redundant glue is discharged through the first U-shaped notch 14 and the second U-shaped notch 24, the top end of the glue at the notch is arc-shaped, and the top end of the glue is still slightly higher than the set glue height. First top separation blade 15 and the second top of U type breach top both sides can play the effect of attracting and guide glue shape as the piece, destroy the whole tension of U type breach department glue, make the glue top level and smooth, inject glue top height.
Preferably, the thickness of each of the first top baffle 15 and the second top baffle 25 is not more than 1 mm. The effect of top separation blade is "drawing" into the plane with the glue top cambered surface of U type breach department, as long as can contact glue can, the excessive thick baffle can influence "flood discharge" effect.
In another embodiment, the bottom of the first U-shaped notch 14 and the bottom of the second U-shaped notch 24 are both arc surfaces, the arc surface at the outer end of the side glue overflow groove 11 is higher than the arc surface at the inner end of the side glue overflow groove 11, and the arc surface at the outer end of the end glue overflow groove 21 is higher than the arc surface at the inner end of the end glue overflow groove 21. Further, the bottom cambered profile shapes of the first U-shaped notch 14 and the second U-shaped notch 24 are in the shape of a monotonously decreasing interval curve of a sine function. Glue overflows from the junction box and overflows to the side glue overflow groove 11 and the end glue overflow groove 21 along the U-shaped notch, and slides downwards along the bottom cambered surface of the U-shaped notch, so that the glue overflows conveniently, and the height of the glue is ensured to be reduced, and the height of the glue is prevented from exceeding the set height.
Preferably, the length of the second U-shaped notch 24 is greater than the length of the first U-shaped notch 14, and the second U-shaped notch 24 can accommodate more glue to overflow.
Preferably, the second U-shaped notch 24 is located at a position intermediate the top ends of the end glue overflow plates 22.
In the glue overflow structure design of the box body of the glue pouring type junction box, one end of the glue pouring opening is easy to overflow due to the fact that a large amount of glue flows into the glue pouring opening when glue is poured, and the glue flows at a low speed to cause more overflow, so that two side glue overflow grooves are formed in one end of the glue pouring opening and are used for accommodating the glue overflowing from two sides due to the fact that the glue does not flow in time; at the end far away from the glue filling opening, the glue flows forwards and overflows forwards, so that a larger port glue overflow groove is arranged in the middle of the glue filling opening and is used for accommodating the surplus overflowing glue when the glue amount is large. The glue overflow groove structure is reasonably designed aiming at the overflow condition of glue at different positions in the glue filling process, and the redundant glue overflows from the U-shaped notch and flows into the glue overflow groove to play a role of flood discharge, so that the influence on the smooth assembly of the upper cover when the glue amount is too much can be effectively avoided.
The present invention has been described in relation to the above embodiments, which are only exemplary of the implementation of the present invention. It should be noted that the disclosed embodiments do not limit the scope of the invention. Rather, it is intended that all such modifications and variations be included within the spirit and scope of this invention.
