Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an end face member for a closure that is disposed at both ends of a closure in order to introduce a cable into the closure while being kept airtight and watertight.
[0002]
[Prior art]
The end face member for closure has been intensively developed. As an example of such a prior art, for example, Japanese Patent Application Laid-Open No. 11-262161 discloses an invention related to an end face seal member in a cable wiring closure. In the prior art, in order to maintain airtightness and watertightness in the cable wiring closure, the end face seal members disposed at both ends of the cable wiring closure are characterized.
[0003]
This prior art will be outlined.
FIG. 7 is a schematic configuration diagram of a conventional end face seal member, FIG. 7 (a) is a front view of a partly separated state, and FIG. 7 (b) is a front view of an assembled state.
In this end face seal member, two cable spacers 100 are respectively attached to two split seal bases 102 that can be opened and closed as shown in FIG. When the end face seal member is closed, the shape is as shown in FIG. In this case, a cable (not shown) is sandwiched from both sides and the cable is sealed.
[0004]
Since the cable spacer 100 is formed of a vulcanized rubber composition having a high elongation rate, when the cable is held in the cable insertion hole 101 that is usually extremely small in diameter, the cable insertion hole 101 expands in accordance with the cable diameter. Thus, the cable insertion hole 101 in a state of being deformed and finally expanded closely contacts the cable.
With such a configuration, the cable wiring closure can be sealed from the external environment, corresponding to cables of various shapes having large and small diameters and irregularities.
[0005]
[Problems to be solved by the invention]
The cable spacer 100 is a relatively soft object as is apparent from the use of a vulcanized rubber composition having a high elongation rate. For this reason, the split seal base 102 disposed on the outer periphery of the cable spacer 100 is made of a relatively hard material such as metal, plastic, rubber having a high hardness, and has a robust structure. The split seal base 102 maintains the shape of the cable spacer 100 and can be easily fitted into a closure case (not shown).
[0006]
However, due to the presence of the split seal base, the end face seal member inevitably increases in size, making it difficult to reduce the size of the entire closure, and further increases the assembly process.
Further, for example, in the case of opening the closure case and removing the cable, it is necessary to first open the divided seal base after opening the closure case, and the wiring workability at the attachment location is poor.
Furthermore, it is necessary to interpose a sealing elastic member between the closure case and the split seal base, which may increase the manufacturing cost.
[0007]
The present invention has been made to solve the above-mentioned problems, and its purpose is to reduce the size, reduce the cost, and improve the workability while holding the cable in an airtight / watertight state. An object of the present invention is to provide an end face member for a closure.

FIG. 3 is a configuration diagram of the appearance of the present embodiment. FIG. 3A is a right side view, FIG. 3B is a front view, and FIG. 3C is a bottom view. 4A and 4B are configuration diagrams of a side surface and a cross section of the present embodiment, in which FIG. 4A is a right side view, FIG. 4B is an AA arrow view, and FIG. 4C is a BB arrow view. FIG. 4 (d) is a view taken along the line CC.
[0018]
As shown in FIG. 1, the end face member 10 for closure is arrange | positioned in the position which opposes when closure case 20A, 20B is closed, These have comprised the pair. The end face members 10 for the closure are arranged on the left and right sides of the end face of the closure, the cables introduced from both sides of the closure are sandwiched between the pair of end face members 10 and sealed from the external environment, and rainwater or the like is introduced from the introduction point of the cable. To prevent intrusion.
The closure case 20A is provided with a fusion splicing tray (not shown) to which a core wire drawn out from the cable for wiring is connected.
[0019]
As shown in FIGS. 2 and 3, the end surface member 10 is provided with a hole portion 1, a cable introduction portion 2, a thin film 3, a reinforcing member 4, and a protruding portion 5 in a rubber member main body. It will be.
As is apparent from FIGS. 2 and 3, the hole 1 is a square hole formed in the member body so as to be continuous in the vertical direction, and three openings are formed in the front surface.
[0020]
The cable introduction portions 2 are provided so as to form a pair on both sides with the hole portion 1 interposed therebetween, and in this embodiment, two cable introduction portions 2 each forming a pair are arranged in three stages in the upper and lower directions. .
The cable introduction part 2 plays the role of determining the passage position in order to allow the cable to pass through the hole part 1. A substantially semicircular blocking film 2 a is provided on the innermost periphery of the cable introduction portion 2. As will be described in detail later, when the cable is introduced, the blocking film 2a located at the innermost periphery moves while being pushed away, and the cable is securely adhered to the blocking film 2a. Further, in the cable introduction part 2 where no cable is introduced, the blocking film 2a also serves to seal from the external environment.
[0021]
On the outside of the semicircular occlusion membrane 2a, there is provided a substantially semicircular thick portion 2b along a concentric circle that is the same center as the center of the semicircle, and the cable introduction portion 2 has a sufficient thickness. It is secured. Due to the thick portion 2b, even when the blocking film 2a is pushed away by the cable in the cable radial direction, the blocking film 2a is prevented from being broken.
Even if the cable moves in the direction of arrow A shown in FIG. 2, the situation where the cable introduction part 2 is broken is avoided.
[0022]
Two thin films 3 that partition the inside of the hole 1 are formed inside the hole 1. As is apparent from FIGS. 2 and 3, the thin film 3 is formed in a bellows shape, and therefore has a play portion that can move freely. Etc. can also be closely attached.
The thin film 3 protrudes from the opening of the hole 1 as clearly shown in FIGS. 4A, 4B, 4C, and 4D in order to ensure that the thin film 3 contacts the cable. It is provided in such a size. As will be described later, the cable surely comes into close contact with the bellows portion of the thin film 3.
[0023]
The reinforcing member 4 is, for example, a relatively hard resin member, or a metal member such as iron or aluminum, and is integrated in the member main body on the back surface of the member main body.
In order to integrally form the reinforcing member 4 in the member main body, the reinforcing member 4 is arranged in a mold for forming the member main body, and is formed so as to be cast by casting rubber. In the present embodiment, such a relatively simple process is only added, and workability is not reduced.
[0024]
The reinforcing member 4 has a substantially corrugated shape that undulates so as to include a concentric circle from the center of the semicircle of the blocking film 2a of each cable introduction portion in the upper and lower stages. The shape of the reinforcing member 4 in the present embodiment is a wave shape as shown in FIGS.
The advantage of having such a corrugated shape is that the shape of the rubber end face member 10 is maintained against various forces applied from the inside and outside.
[0025]
The projecting portion 5 is provided on the back surface of the member main body, and as shown in FIGS. 2 and 3, is a plurality of projecting bodies (four in FIGS. 2 and 3) and is attached to the closure cases 20A and 20B. It is provided for. The closure cases 20A and 20B are also provided with corresponding projecting portions as shown in FIG. 1, and can be attached by fitting these projecting portions together.
[0026]
Since force is also applied to the protruding portion 5 during such fitting work, the end face member 10 tries to deform, but since the protruding portion 5 is provided in the vicinity of the reinforcing member 4 described above, The shape is reliably maintained and can be easily attached to the closure cases 20A and 20B.
[0027]
Three grooves are formed by such four protruding portions 5. The projecting portions of the closure cases 20A and 20B enter into these grooves, reach the member main body at the bottom of the groove, and securely adhere to each other, so that rainwater from the attachment points of the closure cases 20A and 20B and the end face member 10 can be obtained. Make sure to prevent intrusion. Since there are three grooves, even if rainwater enters from the outer groove closest to the external environment (for example, the right or left outer groove in FIG. 3C), the next groove (FIG. 3 ( Intrusion of rainwater is prevented in the central groove in c). As described above, the protruding portion 5 also serves to prevent the rainwater from entering the inside of the closure and seal the closure from the external environment.
[0028]
Next, the operation of the pair of end surface members when closing the closure case will be described. First, the operation of the end face member when closing the closure case without introducing a cable will be described.
FIG. 5 is an explanatory view for explaining an end face member when the closure case is closed without introducing a cable. FIG. 5 (a) is a partial view of a pair of end face members before close contact, and FIG. It is a fragmentary view of a pair of end surface members after adhesion.
[0029]
When the closure case is closed, the pair of cable introduction portions 2 are pressed so as to come into close contact from the left and right, and the gap is reliably closed. In this case, the cable introduction portion 2 as shown in FIG. 5A is deformed by the pressing force from the left and right until it has a shape as shown in FIG.
For this reason, the cable introduction part 2 is sufficiently intimately sealed so as to surely prevent intrusion of rainwater or the like from the outside. In this case, rainwater does not reach the thin film 3.
[0030]
Next, a case where the closure case is closed while the cable is introduced and the cable is held by the end face member will be described.
FIG. 6 is an explanatory view for explaining the end face member when the cable is introduced and the closure case is closed. FIG. 6A is a partial view of the pair of end face members after holding the cable, and FIG. FIG. 6C is a partial view for explaining the state of one thin film 3 and FIG. 6C is a partial view for explaining the state of the other thin film 3.
[0031]
In this case, when the cable is disposed in the vicinity of the blocking membrane 2a of the cable introduction portion 2 and the closure cases 20A and 20B are closed, the cable is disposed in the cable introduction portion 2 while pushing away the closure membrane 2a, as shown in FIG. Thus, the cable is introduced.
In FIG. 6 (a), the cable reaches the innermost circumference of the thick portion 2b, which is a semicircular cutout. However, even in this case, the blocking film 2a is in close contact with the cable, and rainwater enters. Will be surely prevented.
[0032]
In FIG. 6A, the case where the cable diameter is large and the innermost circumference of the thick portion 2b of the cable introduction portion is assumed has been described. However, since the cable diameter is small, the thick portion 2b is not reached. Even in such a case, the blocking film 2a can be in close contact with the cable and sealed from the external environment. For this reason, although it is within a certain range, a cable can be introduced corresponding to the size of the cable diameter and the unevenness of the cable surface.
[0033]
Further, when the cable is introduced, the thin films 3 of the pair of end surface members 10 are in close contact with the cable from both sides. In this case, one thin film 3 is in a state as shown in FIG. 6B, and the other thin film is in a state as shown in FIG. 6C. In this case as well, the cable pushes away the thin film 3 and the thin film 3 is in close contact with the upper and lower sides of the cable, so that the gap is reliably closed. Since such two thin films 3 are alternately overlapped, rainwater or the like from the external environment can be reliably blocked.
[0034]
In the present embodiment, the situation that rainwater enters due to the blocking film 2a of the cable introduction part 2 is almost eliminated, and by any chance a little amount of rainwater passes through the gap generated between the cable introduction groove and the cable. Even if it penetrates into the hole 1, the infiltration of rainwater from the outside is reliably prevented by the blocking action of these thin films 3.
Furthermore, such a thin film 3 is formed in multiple stages (in this embodiment, two stages), rainwater does not reach the closure case body, and a good environment can be maintained in the closure case.
[0035]
Next, an embodiment of an end face member for a closure according to the second invention will be described with reference to the drawings. Note that the structure and the like of the closure are the same as those of the closure described as the first invention, the description thereof is omitted, and only the structure of the end face member 10 ′ will be described. FIG. 8 is a structural perspective view of the present embodiment, and FIG. 9 is an exemplary exploded view of the present embodiment.
[0036]
As shown in FIGS. 8 and 9, the end face member 10 ′ is formed by providing a hole 1, a cable introduction part 2, a thin film 3, and a separation-type projecting part 6 in a rubber member main body. Is.
In the present embodiment, the reinforcing member 4 used in the first embodiment is removed, and a separation-type protruding portion 6 formed of a material having a high rubber hardness (that is, hard) is provided, and the reinforcing member is provided on the separation-type protruding portion 6. The role of
[0037]
The separation-type protruding portion 6 is formed such that a plurality (four in FIG. 8) of protruding portions 6a protrude from the protruding portion main body 6b. Corresponding projecting portions are also provided in the closure cases 20A and 20B shown in FIG. 1, and these can be attached by fitting the projecting portions together as in the embodiment of the first invention. is there.
[0038]
The separation-type protruding portion 6 is integrally formed by being incorporated in the member main body. This forming method will be described. A lump of rubber material having a low hardness is placed in advance in a mold frame (not shown). This lump of rubber material is in such an amount that a member body can be formed, and is in a soft state at a high temperature before being cured.
A mold injection gate (not shown) is provided with a material injection gate so that rubber flows from a position on the protruding portion 6a as shown in FIG. 8, and a rubber material having a high hardness is injected into the mold from this position. Is done. The rubber material to be injected is also in a soft state at a high temperature before curing.
By cooling and solidifying the rubber materials having different hardnesses, an end face member 10 ′ in which the separation-type protruding portion 6 having a high hardness and the member main body having a low hardness are integrated is formed.
In the present embodiment, such a relatively simple process is only added, and workability is not reduced.
[0039]
Since the end face member 10 'is actually formed integrally, the separation-type protruding portion 6 and the member main body cannot be detached after the formation. However, for the sake of explanation, as shown in FIG. When the installation portion 6 and the member main body are separated, the separation-type protruding portion 6 has a large rubber hardness, that is, is hard, and the member main body has a small rubber hardness, that is, is soft. For this reason, although the reinforcing member used in the first invention is eliminated, the protruding portion 6a of the separation-type protruding portion 6 can be made to have a robust structure as in the first invention.
[0040]
Note that the material injection gate as shown in FIG. 8 is injected from six material injection gates on the two inner protrusions 6a out of the four protrusions 6a. In this case, the two outer protruding portions 6a can be formed as a soft rubber material having a low hardness, that is, the same as the member main body. Such a formation is realized by adjusting the amount of the rubber material having a small hardness, which is previously arranged in a mold (not shown).
[0041]
Further, although not shown, if the material is injected from a material injection gate provided so as to be positioned on the two outer protruding portions 6a, the inner two protruding portions 6a have a small hardness. That is, a soft projecting portion that is the same as the member main body can be used.
Further, in order to ensure that the four projecting portions 6a are formed of a rubber material having a high hardness, although not shown, the material injection gate provided so as to be positioned on the four projecting portions 6a is used as a rubber. The material may be injected.
[0042]
In addition, as a concrete material of the separation-type protruding portion 6 and the member main body, both are made of EPDM (Ethylene Propylene Diene Monomer). Assuming that the hardness is A °, the hardness of the separation-type protruding portion 6 is any value from A ° to 60 °.
If A = 1, the hardness of the member body is 1 °, and the hardness of the separating projection 6 is any value from 1 ° to 60 °.
If A = 5, the hardness of the member main body is 5 °, and the hardness of the separating projection 6 is any value from 5 ° to 60 °.
The specific value of A ° is preferably any value within the range of 1 ° to 30 °.
[0043]
When the end face member 10 ′ thus formed is fitted into the closure, a force is also applied to the projecting portion 6 a to deform it, but the projecting portion 6 a has a large rubber hardness as described above. Since it is (hard), its shape is reliably maintained, and can be easily attached to the closure cases 20A and 20B.
In addition, about the function of the cable introduction part 2 and the thin film 3, it has the same structure and function as 1st invention, The description is abbreviate | omitted.
[0044]
The embodiments according to the first and second inventions have been described above.
In these embodiments, three cables are introduced into a pair of end surface members 10 (10 ′), and accordingly, three hole portions 1 and three cable introduction portions are described. The number is not limited to three or three pairs, but may be an arbitrary number such as two or two pairs or four or four pairs.
Further, the number of the thin films 3 or the number of the protruding portions 5 can be set to an arbitrary number as necessary, and these are designed and selected as appropriate.
[0045]
【The invention's effect】
As described above, according to the present invention, the outer peripheral frame that has been conventionally used for the end face member is not required, so that the end face member can be reduced in size and the entire closure can be reduced in size.
Further, in the case of opening the closure case and detaching the cable, it is not necessary to open the outer peripheral frame again after first opening the closure case as in the prior art, and the wiring workability is good.
Furthermore, since the projecting portion (separate-type projecting portion) for attaching to the closure case is a rubber member body, it is possible to sufficiently seal without providing a sealing elastic member separately, which increases the manufacturing cost. Can be suppressed.
[0046]
In general, according to the present invention, it is possible to provide an end face member for a closure that holds a cable in an airtight / watertight state and realizes downsizing, cost reduction, and workability improvement. it can.
