Description

  The present invention relates to an impedance bond installed in a track circuit of a railway track.

  As an impedance bond, for example, a housing (container) is individually provided with a location for storing a capacitor for increasing detection sensitivity and a location for an injection port for injecting a filler (filling resin) to be filled around the transformer. Is known (see Non-Patent Document 1).

  In the manufacture of an impedance bond casing (housing portion) and lid member, there is a demand for reducing the types of molds to be manufactured as much as possible from the viewpoint of cost. However, in the case of the technique disclosed in Patent Document 1, for example, it is necessary to provide lid members on both the side for accommodating the capacitor and the filler inlet side. Furthermore, it is necessary to seal these lid members. This is because the impedance bond is usually installed outdoors, so that it is necessary to increase the waterproof property. From the above, if the number of lid members increases, it may be a problem that the manufacturing cost and the manufacturing period increase. Further, in the case of a configuration that does not require a capacitor in the impedance bond, what is to be done about the location for storing the capacitor provided in the housing (storage portion) can be a problem with the conventional configuration.

  Hereinafter, an example of the impedance bond according to the embodiment will be described with reference to FIG. 1 and the like. FIG. 1 is a conceptual perspective view showing an appearance of an impedance bond 100 according to the present embodiment. FIG. 2A is a conceptual plan view of the impedance bond 100. 2B is a side cross-sectional view of FIG. 2A, and is a cross-sectional view taken along line AA in FIG. In addition, the impedance bond 100 as one aspect of this embodiment is a rectangular parallelepiped box-shaped member as illustrated, and has a transformer inside, for example, installed on the side of a track on which a train runs, It is connected to a rail. In FIG. 1 and the like, as a normal installation state, the downward direction of gravity is the −Z direction, and in a plane perpendicular to the Z direction, the direction in which one side of the rectangular parallelepiped configuration extends is the X direction and is perpendicular to the X direction. The direction in which the other one side surface extending in the direction is defined as the Y direction.

  As shown in FIGS. 1, 2 (A) and 2 (B), the impedance bond 100 is disposed on the main body member BM constituting the transformer, the container member 10 for housing the main body member BM, and the upper surface of the container member 10. And a component member PM housed between the container member 10 and the lid member 20. Further, it is assumed that the filler FL is filled in the container member 10 in which the main body member BM is accommodated.

  Here, as an example of the component member PM, it is assumed that a capacitor member CM for improving detection sensitivity using resonance is accommodated for detection of a current flowing through the rail and the like. Depending on the required detection sensitivity, a mode in which the capacitor member CM is not arranged is also conceivable. That is, a case where a member other than the capacitor is arranged as the component member PM or a case where nothing is arranged can be considered.

  In addition to the above, the impedance bond 100 includes various terminals TE, such as rails and other impedance bonds, as members for flowing a return current across the boundary of the track circuit on the line. Wiring members (not shown) and the like are provided, but descriptions of general matters for functioning as impedance bonds are omitted.

  Here, when the component member PM (capacitor member CM) is stored in the impedance bond 100, it is stored between the container member 10 and the lid member 20 as shown in FIG. More specifically, as illustrated in a partially enlarged plan view in FIG. 3A, the component member PM is the container member 10 in a state where the lid member 20 (see FIG. 2A) is removed. Is placed at a predetermined position on the upper surface side. On the other hand, when the component member PM is not accommodated, it is as illustrated in FIG. That is, as described above, in the case where it is not necessary to improve the sensitivity enough to provide the capacitor member CM in the impedance bond 100, as shown in FIG. It may be completed.

  Hereinafter, returning to FIG. 1 and the like, each part constituting the impedance bond 100 will be described in detail.

  First, in the impedance bond 100, the container member 10 whose main part is formed of a casting is provided on the relatively lower side (−Z side) and covers the periphery together with the lower part that supports the body member BM. The first member (storage lower portion) 10a having a rectangular parallelepiped box shape that forms a plate, and a plate-like first member that forms an upper portion that is provided on the upper side (+ Z side) relatively and covers the upper side of the body member BM. 2 members (storage upper part) 10b. The container member 10 is configured by screwing and fixing four corners of the second member 10b with the four screw members 10c, the first member 10a and the second member 10b respectively manufactured as castings.

  The structure of the container member 10 as the storage container of the main body member BM, that is, the storage container of the transformer will be described in more detail. First, the main body member BM is placed inside the box-shaped first member (storage lower part) 10a. Stored. Thereafter, the upper side (+ Z side) is covered (covered) with a plate-like second member (accommodating upper part) 10b, so that the main body storage space BS for storing the main body member BM (illustrated by a broken line in FIG. 2B). Further, the first member 10a and the second member 10b are fastened by the screw member 10c (see FIG. 1 or FIG. 2A). As described above, the container member 10 keeps the main body member (transformer) BM inside. In this state, the filler FL can be injected into the main body storage space BS, that is, around the main body member (transformer) BM.

  In the above case, the storage lower part (first member) 10a and the storage upper part (second member) 10b of the container member 10 constitute partition walls that define the main body storage space BS. The upper portion (second member) 10b forms a partition portion 30 that partitions at least a part of the upper limit (the upper end on the + Z side) in the main body storage space BS. In other words, the partition part 30 that partitions at least a part of the upper limit of the main body storage space BS is constituted by a partition part provided as one end of the storage upper part (second member) 10b. Further, the partition portion 30 extends along the XY plane (horizontal plane), and in the Z direction (vertical direction; gravity direction), a part for housing the main body member (transformer) BM and a component member PM (capacitor member CM). It is intended to isolate the storage location.

  Furthermore, in this embodiment, the storage upper part 10b of the container member 10 has the insertion part 40 which is a hole part penetrated to the main body storage space BS in addition to the partition part 30 as described above. In this case, the insertion part 40 is a hole that communicates with the main body storage space BS from the upper side (+ Z side) to the lower side, and allows liquid or the like to be injected into the main body storage space BS. The insertion part 40 is a filling port through which the filler FL is injected into the main body storage space BS. This will be described in detail later with reference to FIG.

  On the other hand, in the impedance bond 100, the lid member 20 is provided on the upper side of the storage upper part 10b as shown in the figure, and closes the insertion part 40 of the container member 10 and cooperates with the partition part 30 of the container member 10. Thus, the component storage portion 50 that can store the capacitor member CM as the component member PM is formed. That is, the container member 10 and the lid member 20 cooperate to integrate the insertion portion closing structure that closes the insertion portion 40 and the component storage structure that can store the component member PM.

  Hereinafter, the configuration of the storage upper portion 10b of the container member 10 will be described in more detail. First, as described above, the storage upper part 10 b includes the partition part 30 and the insertion part 40. As shown in the drawing, these are provided on the central side of the plate-like portion 10p which is a main body extending along the XY in-plane direction in the storage upper portion 10b. On the upper surface side of the partition portion 30, a recess portion CV is provided for allowing the capacitor member CM as the component member PM to be fixed at a predetermined position. Moreover, in the partition part 30, the protrusion part TP used also as one side wall of the hollow part CV is formed between the insertion part 40 and the hollow part CV, and the insertion part 40 and the hollow part CV are bordered on the protrusion part TP. And are adjacent.

  Furthermore, the storage upper part 10b includes a container side attaching part 11 for attaching the lid member 20, and four screw receiving parts 12 (see FIG. 3A, etc.) for enabling the lid member 20 to be fastened. Have. The container-side mounting portion 11 is an annular step portion having a shape corresponding to the lid member 20 formed so as to surround the partition portion 30 and the insertion portion 40, and has a protruding shape for fitting with the lid member 20. It has the fitting part 11a. The four screw receiving portions 12 are hole portions (concave portions) provided with threading for screwing with screws 22 (see FIG. 2A and the like) of the lid member 20 described later.

  In addition to the above, the storage upper part 10b is provided on the upper surface of the plate-like part 10p, which is a main body, with a plurality of heat radiation fins FI, FI for heat dissipation (that is, cooling) for heat generation in the main body member (transformer) BM composed of coils and the like. , ... are provided. In the illustrated example, on the upper surface of the plate-like portion 10p, the radiation fin FI is provided in addition to the location where the lid member 20 is attached.

  Next, the configuration of the lid member 20 in the impedance bond 100 will be described in more detail. A lid member 20 whose main part is made of a casting is a plate-like lid body 21 which is a casting, four screws 22, and a packing 23 which is an elastic body provided in an annular shape along the edge of the lid body 21 (see FIG. 4).

  The lid body 21 is a plate-like member having a shape corresponding to the container side mounting portion 11 provided on the container member 10, and the lid side mounting portion 21 a is fitted to the container side mounting portion 11 along the edge. It is provided corresponding to. An example of the shape and the like of the lid-side attachment portion 21a will be described later with reference to FIG.

  As is clear from the description with reference to FIGS. 1 to 3, the four screws 22 are inserted into the screw holes SH of the lid body 21 and further screwed into the four screw receiving portions 12 of the container member 10. The lid member 20 and the storage upper part 10b of the container member 10 are fastened.

  Hereinafter, with reference to FIG. 4 etc., an example of the opening / closing mechanism of the cover member 20 in the said structure is demonstrated.

  First, as shown in FIG. 4 (A), the lid-side mounting portion 21a provided in an annular shape along the edge has a recessed fitting structure (grooved portion) corresponding to the protruding fitting portion 11a. DT is provided and attached to the fitting structure (grooved portion) DT so that the packing 23 is embedded. When the lid member 20 is assembled, when the above-described four screws 22 (see FIG. 2A) are fastened, the lid-side attachment portion 21a moves in the direction of the arrow S1 shown in FIG. 4), the packing 23 sandwiched between the groove-shaped portion DT of the lid-side mounting portion 21a and the fitting portion 11a is slightly deformed, as shown in FIG. 4B as an example. Thus, the lid member 20 can be sealed. When the fastening of the four screws 22 is loosened, the state shown in FIG. 4B returns to the state shown in FIG. 4A, and the lid member 20 can be opened. The lid member 20 can be opened and closed by attaching and removing the four screws 22 as described above.

  Further, as described above, the partition portion 30 and the lid member 20 of the container member 10 form a component storage portion 50 that can store the component member PM (capacitor member CM) in cooperation. It is also. That is, by sealing with the lid member 20, the partition part 30 forms a part on the lower side (−Z side) and the side of the component storage space PS that stores the component member PM (capacitor member CM). The lid member 20 is formed on the upper side (+ Z side) and the other side of the part storage space PS to seal the part member PM (capacitor member CM) and protect it from raindrops and the like. ing.

  Hereinafter, an example of a manufacturing process of the impedance bond 100 according to the present embodiment will be described with reference to the schematic diagrams conceptually illustrated in FIGS. FIG. 5A shows a step of injecting the filler FL (see FIG. 2B and the like) among the steps of manufacturing the impedance bond 100. FIG. 5B shows a process of installing the component member PM (capacitor member CM) after injecting the filler FL. FIG. 5C shows a process of attaching the lid member 20 after installing the component member PM (capacitor member CM). As the filler (filling resin) FL, various materials that are sufficient for cooling the main body member (transformer) BM can be employed.

  First, as a premise, as described above, the main body member (transformer) BM is confined in the container member 10 including the first member 10a and the second member 10b. Thereafter, as shown in FIG. 5 (A), the insertion portion 40 is used as the filling port FP, and the filler FL is injected into the main body storage space BS from the direction indicated by the arrow A1, and as shown in FIG. 5 (B), The main body storage space BS is filled with the filler FL. In this way, the container member 10 and further the container can be obtained by filling (filling) the body storage space BS, that is, the periphery (particularly the upper limit side) of the body member (transformer) BM with the filler FL. The main body member (transformer) BM can be appropriately cooled by the radiation fin FI (see FIG. 1 and the like) attached to the member 10.

  Next, as shown in FIG. 5B, a component member PM (capacitor member CM) is installed on the upper surface side of the container member 10. More specifically, as illustrated with reference to FIG. 2B, FIG. 3A, etc., the component member PM (capacitor member CM) is provided in the recess CV as a predetermined position provided on the upper surface of the partition portion 30. ) Is placed (placed).

  Finally, as shown in FIG. 5C, the lid member 20 is attached to the upper surface of the container member 10. More specifically, as illustrated with reference to FIG. 2 to FIG. 4 and the like, the container member 10 and the lid member 20 are fastened by the screws 22 and the packing 23 constituting the lid member 20. Thereby, the lid member 20 constitutes an insertion portion closing structure that closes the insertion portion 40 as the filling port FP provided in the container member 10. At the same time, the container member 10 and the lid member 20 cooperate to constitute a component storage structure that stores the component member PM (capacitor member CM) placed on the partition portion 30 in a sealed state.

  Further, from the viewpoint of the above, in this embodiment, in this embodiment, the partition part 30 extending horizontally (extending in parallel to the XY plane) is used as a partition part, and the body member (transformer) BM or the like on the lower side (−Z side). Is disposed, and a component member PM (capacitor member CM) is disposed on the upper side (+ Z side). Further, the locations where the filler FL is injected and the locations where the component members PM are taken in and out are integrated into a simple structure. This facilitates simple and quick production, and increases convenience during maintenance and inspection.

  FIG. 6 is a plan view conceptually showing an example of a conventional impedance bond as a comparative example. FIG. 6 is a diagram corresponding to FIG. In the example of FIG. 6, the location for housing the capacitor member CM as the component member PM and the location of the filling port for injecting the filler (filling resin) to be filled around the main body member (transformer) BM are the housing. It differs from the case of FIG. 2 (A) in that it is individually provided in the (housing portion). That is, in FIG. 6, in addition to the container member 10, a component housing lid member for forming a space for housing the component member PM (capacitor member CM) in cooperation with the container member 10 and sealing the space. 20X and a filling port lid member 20Y for sealing the filling port FP of the filler (filling resin) provided in the container member 10 are provided as separate and independent members. In this case, first, in addition to the container member 10, two lid members (casting members) including a component storage lid member 20X and a filling port lid member 20Y are required. In addition, a structure for enabling sealing of each of these is also required. On the other hand, in the present embodiment, as described above, since the lid members can be integrated into one lid member 20, the structure can be simplified and the number of casting members can be reduced.

  Further, in the case shown in FIG. 6, for example, even when the component member PM (capacitor member CM) is not required, the component storage lid member 20 </ b> X and the component storage space provided in the container member 10 corresponding thereto are formed. In order to maintain the sealing property, there is a possibility that a separate operation such as cutting the portion is required. On the other hand, in the present embodiment, as described above, it is sufficient to empty the formed component storage unit 50 (see FIG. 3B), so whether or not the component member PM (capacitor member CM) is necessary. As a change in the manufacturing process accompanying this, it is only necessary to omit the process shown in FIG. That is, the trouble as in the case of FIG. 6 can be omitted. If a component member PM (capacitor member CM) is not required and a container member that does not have the equivalent of the component storage lid member 20X in FIG. 6 is manufactured separately, a new casting needs to be cast. It is considered very disadvantageous.

  Further, as in the case of FIG. 6, when the component storage lid member 20 </ b> X and the filling port lid member 20 </ b> Y are provided, the respective structures are made small so as to maintain the sealing performance (prevent waterproof failure) itself. May be difficult. On the other hand, in the present embodiment, the centralized lid member 20 is made to have a certain size, for example, so that the curvature of the shape of the packing 23 is reduced or the size (thickness) is increased to some extent. Can do. That is, the deformation rate of the packing 23 at the time of sealing can be reduced. Thereby, possibility of degradation, such as generation | occurrence | production of the crack in packing 23, can be reduced, and waterproofness can be improved.

  In addition, as is clear from a comparison between FIG. 6 and FIG. 2A, in this embodiment, the number of radiating fins FI and the area ratio of the plate-like portion 10p that is the main body of the storage upper portion 10b can be increased. In this case, for example, an improvement in heat dissipation (cooling) performance of about 20 to 30% can be expected as compared with the case of FIG.

  Also, when the manufacturing processes are compared, it is clear that the present embodiment is advantageous from the viewpoint of simplification and speed. That is, it can be said that the lead time and the yield are improved as compared with the comparative example by integrating (unifying) the insertion portion closing structure and the component housing structure. For example, in the case of FIG. 6, in order to maintain hermeticity (to prevent poor waterproofing) and the like, after screwing at a screwing location, the location is further waterproofed with an adhesive or the like. In this case, much labor is required at the time of manufacturing and maintenance. In the present embodiment, no work is required.

  As described above, in the impedance bond 100 according to the present embodiment, the container member 10 and the lid member 20 cooperate to store the insertion portion closing structure that closes the insertion portion 40 and the capacitor member CM that is the component member PM. Can be integrated with the component storage structure. Thereby, for example, a filler (filling resin) FL is injected from the insertion portion 40, various component members PM such as a capacitor that may be required in the impedance bond 100 are stored, and further, a member such as a capacitor is originally attached. It is possible to unify such as being able to cope with the selection of whether or not to store. In other words, the integration of various functions makes it possible to provide a structure that is simple and can accommodate various configurations without increasing the types of molds, and can reduce manufacturing costs and manufacturing periods.

  First, in the above description, the capacitor member CM for enhancing the detection sensitivity is stored as the component member PM stored in the component storage unit 50. However, as the component member, the operation and maintenance of the impedance bond can be performed in addition to the capacitor. Various parts and tools necessary for management and the like can be stored.

  In the above description, the heat radiation fin FI is provided in addition to the location where the lid member 20 is attached. However, as shown in FIG. 7A, the impedance bond 100 has an upper surface of the lid member 20. It is also conceivable to provide a radiation fin FI. Further, as shown in FIG. 7 (B), the lid member 20 is embedded and attached to the upper surface of the container member 10 so that the lid member 20 is attached after the lid member 20 is assembled.

In this case, as indicated by a broken line in the figure, the shape of the upper limit UB of the main body storage space BS is also complicated. At this time, as shown in the figure, the partition part 30 partitions at least a part of the upper limit UB of the main body storage space BS, so that a part of the main body member BM is arranged immediately below the partition part 30, and on the upper side thereof The component storage part 50 for storing the component member PM may be formed. That is, in the present embodiment, the partition part 30 forming the component storage part 50 partitions at least a part of the upper limit UB of the main body storage space BS as shown in FIG. The upper limit UB other than the portion partitioned by the partition portion 30 may be present above the partition portion 30 (+ Z side) or below the partition portion 30 (−Z side). Shall be included.

  In the above description, the main part of the container member 10 is composed of the first member (storage lower part) 10a and the second member (storage upper part) 10b. Various aspects are possible for.
