Description

[0001] The invention relates to a cable sleeve for enclosing a connection between at least two underground cables.

[0002] Cable joints are used primarily in the power supply sector to connect one or more consumers to an energy supplier. Cable joints used for extending underground cables are also called "connection joints." Cable joints that connect a main cable (also called a "through cable") to a branch cable leading to a house connection, an electric vehicle charging station, or another consumer are called "cable branch joints."

[0003] Generally, cable joints consist of a housing with through-openings for underground cables at both ends. The housing is divided longitudinally into two sections by these through-openings. The housing has at least one filling opening on its top for a curing resin or other casting compound. A suitable cable connection device (e.g., clamping ring, connector, individual clamps) is located inside the housing to connect the two ends of underground cables or a continuous main cable to a branch cable. After the underground cables are connected, the housing sections are assembled around the underground cable passing through the two through-openings, and the housing is filled with casting compound through the filling opening. Once the casting compound has cured, the connection between the underground cables is insulated and sealed.

[0004] External forces acting on the splice and / or cable connection, e.g., during installation or work on supply lines, can lead to increased stress. This can damage the connection and result in insufficient insulation, which can cause a short circuit.

[0005] DE 199 58 982 C2 describes a joint for insulating and sealing a connection between at least two underground cables, in particular a through cable and a branch cable. The joint has a housing consisting of at least two joinable housing parts with at least one filling opening for a curable casting compound. Two through-openings of the housing for underground cables are arranged between two housing parts and have sealing seats whose cross-sections slightly exceed the cross-sections of the underground cables to be routed through. Sealing elements made of a soft or soft-elastic material are arranged in the sealing seats to close and seal the gaps between the sealing seats and the underground cables, even if the weight of the casting compound compresses the sealing elements above the underground cables. The sealing elements are strips and / or molded parts of a foam material.The strips have an adhesive layer on one side, allowing them to be fixed to an underground cable. Since the cross-sections of the sealing surfaces only slightly exceed the cross-sections of the underground cables, the splice box housing sags only minimally when the casting resin is poured in, until the sealing elements above the underground cable are largely compressed. This prevents the electrically conductive elements from coming too close to the inner wall of the splice box housing. Due to the small gap between the sealing surface and the underground cable, the splice box can only be used with cable cross-sections specifically designed for it. Furthermore, the splice box housing can deflect slightly downwards under the weight of the casting compound between the two sealing surfaces, potentially compromising the required insulation thickness.

[0006] Based on this, the invention aims to create a cable joint that has a wider range of applications with regard to use with underground cables of different cross-sections, effectively prevents insufficient coverage of the electrically conductive elements in the joint housing with casting compound, is better protected against damage caused by external forces acting on underground cables, and helps the installer to avoid installation errors.

[0007] The problem is solved according to the invention by a cable joint according to claim 1. Advantageous embodiments of the cable joint are specified in the dependent claims and in the description.

[0008] The cable sleeve according to the invention for enclosing a connection between at least two underground cables, in particular a serial connection of two underground cables or a connection between a main cable and a branch cable, comprises • a sleeve housing, • Through-openings for underground cables at both ends of the splice box, • Outwardly facing, hollow bulges in two opposing side walls of the sleeve housing and • at least one filling opening for a hardenable casting compound on the top of the sleeve housing, • wherein the sleeve housing is divided longitudinally into two housing parts through the two end through-openings, so that the two housing parts can be joined together around an underground cable running through the end through-openings, • an insertable spacer which can be inserted into the recesses with its two ends in order to hold the insertable spacer next to at least one underground cable running through the two end-side through-openings in the sleeve housing and • at least one device for fixing at least one underground cable to the insertion platform.

[0009] In the assembled state of the cable joint according to the invention, the insert web is held in place at both ends by the recesses in the joint housing. This fixing device secures at least one underground cable to the insert web. This can be a single underground cable connected in series with another underground cable. Alternatively, it can be a through cable and a branch cable branched off from it. The recesses preferably each have at least one contact surface on their upper side for the ends of the separating web and, next to the contact surface, an inwardly inclined chamfer for channeling air pockets towards the filling opening. This ensures that no air pockets remain in the recesses when casting compound is poured in.The weight of the casting compound prevents the joint housing from shifting downwards relative to the underground cables, as the housing is held in place by the bulges at both ends of the insert. This prevents the joint housing from approaching the live parts and the insulating thickness of the casting compound from being insufficiently reduced. This allows the use of sealing elements that can bridge large gaps between the underground cables and the cable entry openings, as they are not subjected to high loads from the joint housing due to the weight of the cast material. Consequently, the same cable joint can be used for different underground cables with varying cross-sections. This reduces the effort required to provide cable joints for different applications.Furthermore, at least one underground cable is secured to the mounting bracket by the device, so that any external force acting on the underground cable is distributed across the entire system and prevents localized force increases that could damage the resin insulation to such an extent that the cable connection fails, e.g., due to a short circuit. This strain relief also prevents damage to the clamping ring and its connection to the secured underground cable.

[0010] According to one embodiment of the invention, the splice closure housing is divided vertically. This is advantageous for joining the housing parts, as they can be joined horizontally from both sides of the underground cables. Furthermore, dividing the splice closure housing vertically is advantageous for its manufacture. It is preferably manufactured by injection molding from plastic. Dividing the splice closure housing vertically avoids undercuts in the injection mold.

[0011] In another embodiment, the socket housing is divided by the filling opening. This is also advantageous for manufacturing the socket housing by injection molding from plastic.

[0012] According to another embodiment, the device for fixing the underground cables to the mounting bracket comprises at least one cable tie designed to be looped around the at least one underground cable and to tension it against the mounting bracket. The cable tie allows the at least one underground cable to be connected to the mounting bracket sufficiently firmly to withstand the loads from the poured casting compound and any tensile force exerted on the underground cable. Fixing the cable with the cable tie is simple to perform.

[0013] According to another design, the cable tie is passed through holes in the insert on both sides of the at least one underground cable.

[0014] This allows a single underground cable, next to which the mounting bracket is positioned, or two underground cables, between which the mounting bracket is positioned, to be fixed to the mounting bracket. This also allows for lateral fixing of at least one underground cable, preventing it from shifting laterally. Alternatively, to fix two underground cables to the mounting bracket, the cable tie can be looped around both cables next to the mounting bracket and tightened, thus tensioning the two cables against the mounting bracket.

[0015] In another embodiment, the cable tie is designed to be looped around the at least one underground cable and the outer ends of the insert bracket. This allows a single underground cable, next to which the insert bracket is located, to be fixed to the insert bracket. Alternatively, this allows two underground cables, between which the insert bracket is positioned, to be fixed to the insert bracket.

[0016] According to another embodiment, the two housing parts are designed to press a cable tie, wrapped around the ends of the insert web, against the outer surfaces of both ends of the insert web when the housing halves are joined. This allows the fixing of the at least one underground cable to the insert web to be tightened. Furthermore, this achieves lateral fixing of the at least one underground cable, preventing it from shifting laterally.

[0017] According to another embodiment, the insert has guides on at least one side for the cable tie. These guides prevent the cable tie from slipping off the insert and simplify its application.

[0018] According to another embodiment, the device for fixing the at least one underground cable to the insertion platform comprises at least one cable clamp that can be fixed to clamp feet on one side of the insertion platform in order to accommodate and fix at least one underground cable on that side of the insertion platform. For fixing two underground cables, the fixing device comprises two cable clamps that can be fixed to clamp feet on opposite sides of the insertion platform in order to accommodate and fix the two underground cables on opposite sides of the insertion platform.

[0019] According to another embodiment, the divider has interlocking profiles and / or snap-fit ​​elements at both ends and in the recesses on the bearing surfaces for the divider, in order to secure the divider in the recesses during assembly. This simplifies assembly. According to yet another embodiment, the snap-fit ​​elements are designed to be removable, allowing for adjustments during assembly if necessary.

[0020] According to another embodiment, the protrusions are arranged adjacent to a through-opening or to a sealing seat adjacent to the through-opening. This positions the strain relief as far away as possible from the cable connection in order to keep the tensile loads acting on the at least one fixed underground cable as far away as possible from the cable connection technology used.

[0021] In another embodiment, the two housing parts are pivotally connected to each other via a first joint on one side of the joint housing, with a joint axis extending longitudinally along the joint housing. This first joint facilitates the installation of the joint housing on the underground cables.

[0022] According to another embodiment, the first joint has plug-in tongues and plug-in openings arranged on adjacent edges of the two housing parts. These tongues and plug-in openings are designed to be plugged together, pivoting the two housing parts about the joint axis. Using these plug-in tongues and plug-in openings, the splice closure housing can be assembled at the installation site from the two housing parts by plugging them together from opposite sides of the underground cables and then pivoting them together. This simplifies the installation process.

[0023] According to another embodiment, the socket housing has hinged housing parts about a first hinge on the underside. The filling opening is formed between the housing parts. The socket housing has at least one closing flap at the filling opening, which is connected to a housing part via a second hinge with a hinge axis extending longitudinally along the socket housing. At a distance from the second hinge, the closing flap has at least one snap hook that can be engaged with a locking edge on the other housing part when the two housing parts are fully pivoted together. The closing flap secures the socket housing in the folded position of the housing parts and closes the filling opening.

[0024] According to another embodiment, the closure flap has snap hooks positioned at different distances from the second hinge. A first snap hook, located closer to the second hinge, engages with a locking edge on the other housing part when the two housing parts are fully pivoted together. A second snap hook, located further away from the second hinge, engages with its locking edge when the two housing parts are only partially pivoted together. This embodiment allows the splice closure housing to be mounted on the underground cables in two different pivot positions. This enables adaptation, particularly to different cable connection technologies, such as larger clamping rings, to ensure the required coverage of the cables and the clamping ring with casting compound.Furthermore, the filling opening can be closed after pouring in the casting compound by closing the flap.

[0025] In both pivot positions, the socket housing can be closed at the top using the locking flap. In the pivot position where the housing parts are only partially pivoted together, the socket housing can be fitted with sealing elements at the ends, which close the gaps between the two housing parts.

[0026] According to another embodiment, the branch coupling has at least two adjacent locking flaps. By closing one of the two locking flaps, the branch coupling can be fixed in the folded position of the two housing parts. Casting compound can be poured in through the filling opening next to the still-open locking flap, and then this locking flap can also be closed. In addition, multiple filling openings allow the coupling housing to be filled with casting compound on slopes, whereby the casting compound is poured in through the highest filling opening and the remaining locking flaps are closed.

[0027] According to another embodiment, the cable joint housing has at least one filling port on its upper side, with the filling opening located at the top edge. The filling port facilitates the complete filling of the cable joint with casting compound.

[0028] According to another embodiment, the sleeve housing has a sealing seat adjacent to each of the through-openings for a sealing element to seal at least one underground cable passing through the through-opening.

[0029] According to another embodiment, the cable joint housing has, on at least one side and at various distances from an end through-opening, different sealing seats for a sealing element to seal at least one underground cable running through the through-opening, in order to selectively seal the underground cable at various distances from the through-opening. This allows the cable joint to be adjusted to different cable cross-sections and cable connection techniques in order to ensure the required coverage of the current-carrying parts with casting compound and to optimize the amount of casting compound used.

[0030] According to another embodiment, the cable sleeve comprises a clamping ring which has clamping devices, devices for clamping the clamping devices with two underground cables, contact elements, a device for clamping the contact elements with the conductors of the two underground cables and electrical connection devices between mutually assigned contact elements for the various underground cables and is designed to be placed around both underground cables in the sleeve housing and to connect the conductors of the two underground cables to be connected.

[0031] The invention will be explained in more detail below with reference to the accompanying drawings of exemplary embodiments. The drawings show: Fig. 1. A cable joint in a tightly closed state in a top view; Fig. 2. A housing part of the same cable gland in a side view; Fig. 3 another housing part of the same cable gland in a side view; Fig. 4 the same cable joint in a vertical section perpendicular to the longitudinal direction; Fig. 5 the same cable joint in a fully closed state in a top view; Fig. 6a-c a cable sleeve with a differently designed device for fixing the underground cables to the insertion web with a cable tie in a vertical section perpendicular to the longitudinal axis; Fig. 7 a cable sleeve with a device for fixing the underground cables to the insertion web with two cable clamps in a vertical section perpendicular to the longitudinal direction.

[0032] According to Fig. 1, Fig. 2, Fig. 3 to Fig. 4 has a cable sleeve 1 an elongated, hollow sleeve housing 2 which has through openings 3, 4 at both ends for underground cables 5, 6.

[0033] The sleeve housing 2 essentially has five sections: In the center it has a main section 2.1 with an essentially oval cross-section with the largest radius in the lower part and the smallest radius in the upper part.

[0034] Starting from the through-opening 3, it has a socket neck 2.2 with an oval cross-section. The socket neck 2.2 is connected at the other end to the main section 2.1 via a gradually widening transition area 2.3.

[0035] Furthermore, the socket housing 2 has a circular cylindrical socket neck 2.4, which has the through-opening 4 at one end. At the other end, the circular cylindrical socket neck 2.4 is connected to the main section 2.1 via a gradually widening transition area 2.5.

[0036] The sleeve neck 2.2 with the oval cross-section has hollow protrusions 7, 8 projecting outwards on both sides.

[0037] The protrusions 7, 8 each have a flat lower bearing surface 7.1, 8.1 and flat upper bearing surfaces 7.2, 7.3, 8.2, 8.3 on both lateral edges. Between the two upper bearing surfaces 7.2, 7.3, 8.2, 8.3, each protrusion 7, 8 has a chamfer 7.4, 8.4, which is directed upwards and towards the vertical parting line 9 between two joinable housing parts 2.6, 2.7 of the sleeve housing 2 (see figure). Fig. 4).

[0038] A separating bar 10 can be inserted with its two ends 10.1,10.2 into the recesses 7, 8, so that it rests with the undersides of its two ends on the support surfaces 7.1, 8.1 and with the tops of its two ends on the contact surfaces 7.2, 7.3, 8.2, 8.3.

[0039] The separating web 10 has two spaced-apart holes 11.1, 11.2 in a central section 10.3 between its two ends. The separating web 10 can be positioned between a main cable 5 and a branch cable 6, such that the main cable 5 rests on the underside and the branch cable 6 on the top side of the separating web 10. The two underground cables 5, 6 can be fixed to the separating web 10 by means of a cable tie 12, which is looped around the main cable 5 and the branch cable 6 and passed through the holes 11.1, 11.2 in the separating web 10.

[0040] Both socket necks 2.2, 2.4 have a circumferential sealing seat 13, 14 on their inner circumference adjacent to the through-opening 3, 4. The socket neck 2.2 with the oval cross-section has a further sealing seat 15 at a distance from this. The protrusions 7, 8 are arranged between the two sealing seats 13, 15 of the socket neck 2.2 with the oval cross-section, with the protrusions 7, 8 being arranged adjacent to the sealing seat 13, which is located next to the through-opening 3 (see figure). Fig. 2, Fig. 3).

[0041] The cross-section of the main section 2.1 is shaped and dimensioned in such a way that a clamping ring 16 for connecting the through cable 5 to the branch cable 6 can fit inside it.

[0042] The socket housing 2 has several adjacent filling shafts 17.1 to 17.4 with filling openings 18.1 to 18.4 at the upper edge on its upper surface. The filling shafts 17.1 to 17.4 are arranged on the upper surface of the main section of the socket housing 2.1, the housing neck 2.2 with the oval cross-section, and the transition section 2.3 from this housing neck to the main section 2.1 (see Figure 2). Fig. 1).

[0043] The vertical separation plane 9 runs through the end-side through-openings 3, 4 and through the filling openings 18.1 to 18.4.

[0044] The two housing parts 2,6, 2.7 have outwardly projecting flanges 20.1, 20.2 at their lower edges 19.1, 19.2. One housing part 2.6 has rectangular insertion openings 21 in the flange 20.1. The other housing part 2.7 has tabs 22 projecting downwards from the flange 20.2, on which hook-shaped insertion tongues 23 are formed (see figure). Fig. 2, Fig. 3).

[0045] The two housing parts 2.6, 2.7 each have an upwardly projecting lateral shaft wall 24.1, 24.2 of the filling shafts 17.1 to 17.4, offset outwards at their upper edge towards the partition plane 9. Furthermore, the two housing parts 2.6, 2.7 each have partition wall sections 25.1, 25.2 at their upper edge, which extend from the lateral shaft wall 24.1, 24.2 to the partition plane 9 of the two housing parts 19.1, 19.2. The partition wall sections 25.1, 25.2 abut each other at the partition plane 9 when the housing parts 2.6, 2.7 are assembled. Overall, the filling shafts 17.1 to 17.4 are thus bounded by the side shaft walls 24.1, 24.2 and the partition wall sections 25.1, 25.2 (see Fig. 1-3).

[0046] According to Fig. 3 The housing part 2.7 is connected to a closure flap 27 at the upper edge of the lateral shaft wall 24.2 via a film hinge 26. This closure flap extends – divided into several sections – over the entire length of the sleeve housing 2. The closure flap 27 has snap hooks 28, 29 on its underside at various distances from the film hinge 26, with one snap hook 28 located approximately halfway along the length of the closure flap 27 and another snap hook 29 at the end of the closure flap 27. On the side facing away from the film hinge 26, the closure flap 27 has a further film hinge 30 in addition to the aforementioned snap hooks 28.

[0047] The other housing part 2.7 has a locking edge 31 on the upper edge of the side shaft wall 25.1, with which the snap hooks 28, 29 of the locking flap 27 can be snapped into place.

[0048] For the installation of the branch sleeve 1, a main cable 5 is connected to a branch cable 6 via a clamping ring 16. The branch cable 6 is positioned above the main cable 5.

[0049] A separating bar 10 is inserted between the through cable 5 and the branch cable 6. When the two housing parts 2.6, 2.7 are folded together, the ends 10.1, 10.2 of the separating bar 10 fit into the recesses 7, 8 of the two housing parts 2.6, 2.7. If necessary, the splice housing 2 or the separating bar 10 is shifted slightly longitudinally along the splice housing 2 so that the separating bar 10 is inserted precisely into the recesses 7, 8.

[0050] Furthermore, sealing elements 32, 33, e.g., made of foam, are attached to both sides of the clamping ring 16 on the underground cables 5, 6. On the side where the through cable 5 and the branch cable 6 extend away from the clamping ring 16, a sealing element 32 with an approximately oval cross-section is attached. On the side where only the through cable 5 extends away from the clamping ring 16, an approximately circular sealing element 33 is attached. Foam molded parts are generally glued in place.

[0051] The two housing parts 2.6, 2.7 are brought into contact with the main cable 5 and the branch cable 6 from different sides, so that the clamping ring 16 is located in the area of ​​the main section 2.1. The two housing parts 2.6, 2.7 are joined together, with the hook-shaped plug-in tongues 23 of one housing part 2.7 first being inserted into the plug-in openings 21 of the other housing part 2.6. Then, the two housing parts 2.6, 2.7 are pivoted together about the pivot axis of a first joint 34 formed by the plug-in tongues and the plug-in openings until the two housing parts 2.6, 2.7 are abutting each other. In this position, the sleeve housing 2 is in Fig. 1 shown.

[0052] When the housing parts 2.6, 2.7 are pivoted together, the sealing elements 32, 33 come into contact with the sealing seats 13, 14 next to the through openings 3, 4.

[0053] In the folded state, the two housing parts 2.6, 2.7 can be secured by means of the locking flap 27 or an externally acting clamping device. Preferably, the locking flap 27 is divided so that one part of the locking flap 27 can be closed to secure the two housing parts 2.6, 2.7 in the folded position, and the other part of the locking flap 27 initially remains open for filling casting compound into a filling opening 18.1 to 18.4.

[0054] Finally, the casting compound is poured into the socket housing 2 through a filling opening 18.1 to 18.4 until it rises into the filling channels 17.1 to 17.4. The casting compound entering the socket housing 2 displaces the air to the outside through the filling channels 17.1 to 17.4. Due to the chamfers 7.4, 8.4, the air can also escape from the recesses 7, 8. The sealing elements 32, 33 at the ends prevent the casting compound from escaping at the ends of the socket housing 2.

[0055] The shutter flap 27 can then be closed. The outwardly projecting section of the shutter flap 27 can be folded back against the first section of the shutter flap 27 via the further film hinge 30.

[0056] After the casting compound has hardened, it encases the live parts of the connection between the main cable 5 and the branch cable 6. The separating web 10 and the fixing of the underground cables 5 and 6 to it ensure that a minimum thickness of the insulating layer formed by the hardened casting compound is achieved everywhere. Because the joint housing 2 is connected to the separating web 10 via the protrusions 7 and 8, the weight of the casting compound prevents the joint housing 2 from sagging relative to the clamping ring 16 and thus prevents the required insulation layer thickness from being compromised.

[0057] Furthermore, the connection of the underground cables 5, 6 with the separating bridge 10 and the sleeve housing 2 prevents the casting compound from tearing open due to the action of a tensile force on the branch cable 6 and a short circuit from occurring due to penetrating moisture, or the clamping ring 16 or its connection with the conductors of the underground cables 5, 6 from being damaged.

[0058] Since the sleeve housing 2 is supported on the cables 5, 6 via the separating web 10, soft sealing elements 32, 33 with a large wall thickness can be inserted into the sealing seats 13, 14 to bridge the gap between the underground cables 5, 6 and the sealing seats. This makes it possible to use the cable sleeve 1 for connections of underground cables 5, 6 with widely varying cross-sections.

[0059] The dimensions and design of the clamping rings 16 can vary depending on the cross-sections of the underground cables 5, 6 to be connected. For larger cable cross-sections, clamping rings 16 can be used which, in addition to a section 16.1 for clamping to the main cable 5, have several sections 16.2 (“ears”) for connecting to the conductors of a branch cable 6 (see figure). Fig. 5) To accommodate these larger clamping rings 16 in the sleeve housing 2, the housing parts 2.6, 2.7 can be pivoted together in a pivoting position in which they do not touch each other at the top. In this pivoting position, the two housing parts 2.6, 2.7 can be secured by pivoting the locking flap 27, whereby the snap hook 29 furthest from the first film hinge is locked with the locking edge 31 on the filling openings 18.1 to 18.4.

[0060] The same sealing elements 32, 33 as used in the application according to can be used to seal the socket housing 2 at the ends. Fig. 1. If necessary, sealing elements 32, 33 can be used for this purpose, which are adapted to the dimensions of the through-openings 3, 4 in the only partially pivoted state of the two housing parts 2.6, 2.7.

[0061] Any gaps remaining between the ends of housing parts 2.6, 2.7 when they are only partially pivoted together can be closed by additional sealing elements before the casting compound is poured in.

[0062] Fig. Figure 6a shows an alternative method of fixing the underground cables 5, 6 to the separating web 10, in which the cable tie 12 is looped around both underground cables 5, 6 and around the ends 10.1, 10.2 of the separating web 10. The cable tie 12 is pressed against the ends of the separating web 10 by the bearing surfaces 7.1, 8.1 and the contact surfaces 7.2, 7.3, 8.3 of the projections 7, 8. By tightening the cable tie 12, the underground cables 5, 6 are clamped to the separating web 10.

[0063] According to Fig. 6b the separating web 10 has groove-shaped guides 35.1, 35.2 on the top and bottom sides, which receive the cable tie 12 placed around the ends and prevent it from slipping sideways.

[0064] According to Fig. 6c the pre-tensioned cable tie 12 can be re-tensioned by closing the housing halves 2.6, 2.7 in the direction of the arrow until it rests against the ends 10.1,10.2 of the separating web 10.

[0065] According to Fig. The underground cables 5 and 6 are fixed to the separating web 10 by means of cable clamps 36 and 37. Each cable clamp 36 and 37 has an arc section 36.1 and 37.1, respectively, and laterally projecting clamp feet 36.2, 36.3, 37.2, and 37.3 connected to the ends of the arc section. The dimensions of the cable clamps 36 and 37 are adapted to the cross-sections of the main cable 5 and the branch cable 6. The cable clamps 36 and 37 are placed around the main cable 5 and the branch cable 6 from different sides and are screwed to the clamp feet 36.2, 36.3, 37.2, and 37.3 on different sides of the separating web 10. With suitable design of the cable clamps 36, 37, the screw connection can be made by means of two screw connections 38 with each a screw 38.1 and a nut 38.2, which are each passed through two clamp feet on different sides of the separating web 10 at both ends.

[0066] For connecting underground cables 5, 6 with smaller cross-sections, it may be sufficient if the joint housing 2 is filled with casting compound only over a smaller portion of its length. For this purpose, the sealing element 32, 33 can be inserted into the sealing seat 15, which is not directly adjacent to the through-opening 3, but is located further away from it, as shown in Fig. Figure 2 shows that in this case, only the cavity remaining between the underground cables 5, 6 and the clamping ring 16, between the two housing parts 19.1, 19.2 and the sealing elements inserted into the sealing seats 13, 15, is filled with casting compound.
