Description

Technical Field

[0001] The present invention relates to a high-voltage cable connector and a method for applying a chemical agent to the high-voltage cable connector.

Background Art

[0002] For example, in devices such as an electron beam irradiation device and an X-ray generation device, electrons are accelerated to generate an electron beam. The generation of the electron beam is performed, for example, by emitting thermoelectrons from a filament into space by heating the filament and accelerating the thermoelectrons until they reach a predetermined energy. The acceleration of the thermoelectrons is performed, for example, by applying a high voltage between the filament and an electrode located at a position away from the filament. By applying a negative voltage to the filament and a positive voltage to the electrode, the thermoelectrons are accelerated from the filament toward the electrode.

[0003] The high voltage is supplied from a DC high voltage power supply to the above-described device via a high voltage cable. The high voltage cable is connected to the above-described device using a high voltage cable connector to which the high voltage cable is attached. As this type of high voltage cable connector, for example, a high voltage connector described in Patent Document 1 has been proposed.

[0004] [[ID=2V]]As shown in FIG. 9, the high voltage connector 100 described in Patent Document 1 includes a housing 101, a high voltage terminal 102 disposed in the housing 101, and an insulating sealing material 103 filled in the housing 101. The high voltage terminal 102 is connected to a high voltage cable 104 introduced into the housing 101 from a side wall portion of the housing 101. The high voltage cable 104 has a structure in which a conductor portion 105 is covered with a rubber-insulating covering portion 106. The high voltage cable 104 is usually fixed to the side wall portion of the housing 101 so as not to move. The high voltage terminal 102 is connected to the electrode of the above-described device and conducts the high voltage cable 104 and the electrode. The insulating sealing material 103 seals the tip portion of the high voltage cable 104 and the high voltage terminal 102 in the housing 101.

[0005] [Patent Document 1] Japanese Patent Publication No. 2008-293868 [Overview of the project] [Problems that the invention aims to solve]

[0006] In the conventional high-voltage cable connector described above, resin is used as the material for the insulating sealant 103. A fluid liquid resin is injected into the housing 101, and the resin is hardened within the housing 101, thereby forming a solid insulating sealant 103 within the housing 101.

[0007] As shown in Figure 10, before the resin is injected into the housing 101, chemicals 107 and 108 are applied to the inner surface of the housing 101 and the outer surface of the tip 109 of the high-voltage cable 104 housed inside the housing 101. Chemical 107 is applied to the inner surface of the housing 101, for example, to inhibit the resin injected into the housing 101 from adhering to the housing 101 once it hardens. On the other hand, chemical 108 is applied to the outer surface of the tip 109 of the high-voltage cable 104, for example, to assist in the resin injected into the housing 101 from adhering to the tip 109 of the high-voltage cable 104 once it hardens. In this way, different types of chemicals 107 and 108 are applied to the inner surface of the housing 101 and the outer surface of the tip 109 of the high-voltage cable 104. Alternatively, chemical 107 may be applied only to the inner surface of the housing 101, or chemical 108 may be applied only to the outer surface of the tip 109 of the high-voltage cable 104.

[0008] In the application process of the chemicals described above, it is difficult to properly apply the chemicals to areas where the inner surface of the housing 101 and the outer surface of the tip 109 of the high-voltage cable 104 are in close proximity. This can result in unintended chemicals adhering to the inner surface of the housing 101 and the outer surface of the tip 109 of the high-voltage cable 104 when chemical 107 is applied to the inner surface of the housing 101, or chemical 108 adhering to the inner surface of the housing 101 when chemical 108 is applied to the outer surface of the tip 109 of the high-voltage cable 104. If unintended chemicals adhere to the inner surface of the housing 101 and the outer surface of the tip 109 of the high-voltage cable 104, it can lead to molding defects in the insulating sealant (resin sealing defects).

[0009] The present invention has been made in view of the above circumstances and aims to provide a high-voltage cable connector capable of appropriately applying different agents and a method for applying agents to a high-voltage cable connector. [Means for solving the problem]

[0010] A first aspect of the present invention relates to a high-voltage cable connector. The high-voltage cable connector of the present invention is characterized by comprising: a high-voltage cable connected to a high-voltage power supply; a housing having an introduction section for introducing the high-voltage cable into the interior and a housing section for housing the tip of the high-voltage cable in an internal space; and a movable member attached to the outer surface of the high-voltage cable and provided inside the introduction section so as to be slidable in a direction approaching and moving away from the internal space.

[0012] A second aspect of the present invention relates to a method for applying a chemical agent to a high-voltage cable connector, which comprises a high-voltage cable connected to a high-voltage power supply, a housing having an introduction section for introducing the high-voltage cable into the interior, and a housing section for housing the tip of the high-voltage cable in the interior space. The method for applying a chemical agent to a high-voltage cable connector of the present invention is characterized by comprising the steps of: sliding a movable member, which is attached to the outer surface of the high-voltage cable and provided inside the introduction section so as to be slidable in a direction toward and toward the interior space, toward the interior space to allow the tip of the high-voltage cable to enter the interior space from a predetermined position; applying a chemical agent to the outer surface of the tip of the high-voltage cable and / or the inner surface of the housing section; and sliding the movable member toward the direction toward away from the interior space to return the tip of the high-voltage cable to the predetermined position. [Effects of the Invention]

Mode for Carrying Out the Invention

[0015] Hereinafter, embodiments of a high-voltage cable connector of the present invention and a method of applying a chemical agent to the high-voltage cable connector will be described in detail with reference to the drawings. In the following description, expressions distinguished by the presence or absence of “… part” such as “end part” and “end” are used. For example, “end” means the end part of an object, but “end part” means a region having a certain range including the “end”. Any point within a certain range including the end is considered to be an “end part”. The same applies to other expressions with “… part”.

[0016] Description of high-voltage cable connectors FIGS. 1 and 2 show a schematic configuration of a high-voltage cable connector 1 according to an embodiment. The high-voltage cable connector 1 is used for equipment that requires supply of high voltage, such as an electron beam irradiation device or an X-ray generation device.

[0017] The high-voltage cable connector 1 includes a high-voltage cable 2 connected to a high-voltage power source, a housing 3 having an introduction part 32 for introducing the high-voltage cable 2 therein, and a movable member 6 attached to the outer surface of the high-voltage cable 2 and provided inside the introduction part 32. Further, the high-voltage cable connector 1 includes a high-voltage terminal 5 for electrically connecting the high-voltage cable 2 to an electrode of a device such as an electron beam irradiation device or an X-ray generating device, and an insulating sealing material 4 provided inside the housing 3. Note that the high-voltage cable connector 1 includes other members as necessary in addition to the members 2-6 described above.

[0018] Description of high-voltage cables As shown in FIGS. 1 and 2, the high-voltage cable 2 includes a conductor part twenty and a covering part twenty-one, and has a structure in which the conductor part twenty is covered with the covering part twenty-one. The covering part twenty-one has insulation that is difficult to conduct electricity and heat. Examples of the material of the covering part twenty-one include synthetic rubbers such as butyl rubber, ethylene propylene rubber, and silicone rubber in addition to natural rubber. Note that the high-voltage cable 2 may be protected by further covering the covering part twenty-one with a sheath. The high-voltage cable 2 has a cross-sectional shape (a cross-section cut perpendicular to the length direction of the high-voltage cable 2) that is, for example, circular. The high-voltage cable 2 can be a conventionally known one.

[0019] Description of the enclosure As shown in FIGS. 1 and 2, the housing 3 includes a housing part thirty-four formed in a bottomed cylindrical shape and a cylindrical introduction part thirty-two connected to the housing part thirty-four. The housing part thirty-four has an opening at the upper part, and the sealing material 4 and the high-voltage terminal 5 are accommodated through the upper opening into the internal space thirty-three. insulation Examples of the material of the housing 3 include metal and insulating materials having high thermal conductivity, and preferably metal.

[0020] It should be noted that there seems to be an error in the text where "導体部20及び被覆部21" is translated as "conductor part twenty and covering part twenty-one", it should probably be something like "conductor part 20 and covering part 21". Please check and correct if this is a real mistake in the original text.The storage section 34 comprises a bottom section 30 and side wall sections 31. The bottom section 30 is connected to the lower end of the side wall section 31, and the space enclosed by the side wall section 31 above the bottom section 30 is the internal space 33. The upper end of the side wall section 31 defines the upper opening of the storage section 34. A through hole is formed in the side wall section 31 that penetrates in the thickness direction, and an introduction section 32 is connected to the side wall section 31 so as to protrude horizontally from this through hole.

[0021] In the housing 3, the high-voltage cable 2 is introduced from the introduction section 32 through a through-hole in the side wall section 31 into the interior of the housing section 34. The tip portion of the high-voltage cable 2 that protrudes into the internal space 33 of the housing section 34 (hereinafter referred to as "the tip portion 22 of the high-voltage cable 2") is housed in the internal space 33.

[0022] Explanation of high-voltage terminals As shown in Figure 1, the high-voltage terminal 5 is housed in the internal space 33 of the housing 34. The material of the high-voltage terminal 5 can be a low-resistivity metal such as copper or brass. The conductor portion 20 at the tip 22 of the high-voltage cable 2 is connected to the high-voltage terminal 5 by being inserted into the high-voltage terminal 5. The high-voltage terminal 5 is provided with a recess 50 that can be used to set, for example, a part of an electrode, in order to connect the high-voltage cable 2 to an electrode of equipment such as an electron beam irradiation device or an X-ray generator.

[0023] Explanation of insulating encapsulant As shown in Figure 1, the insulating sealant 4 is molded into the internal space 33 of the housing 34, sealing the tip 22 and high-voltage terminal 5 of the high-voltage cable 2 within the internal space 33. In other words, the tip 22 and high-voltage terminal 5 of the high-voltage cable 2 are embedded in the insulating sealant 4 inside the housing 34. The insulating sealant 4 is molded into the internal space 33 of the housing 34 by the curing of the resin.

[0024] The resin used as the material for the insulating sealant 4 is a thermosetting resin. Examples of thermosetting resins include epoxy resin, silicone resin, phenolic resin, polyimide resin, and urethane resin.

[0025] The high-voltage cable 2 is inserted from the introduction section 32 into the internal space 33 of the housing section 34, and the tip 22 of the high-voltage cable 2 is connected to the high-voltage terminal 5 housed in the internal space 33 of the housing section 34. In this state, a thermosetting resin, which is in a liquid state that is fluid at room temperature, is injected into the internal space 33 of the housing section 34, and the thermosetting resin is heated in the internal space 33 to harden it. As a result, a solidified insulating sealant 4 is formed in the internal space 33 of the housing section 34, and the tip 22 of the high-voltage cable 2 and the high-voltage terminal 5 are sealed in the internal space 33 by the insulating sealant 4.

[0026] Movable member As shown in Figures 1 and 2, the movable member 6 is slidable within the introduction section 32 in a direction that moves toward and away from the internal space 33 of the housing section 34. The movable member 6 is slidable because the internal space 33 of the housing section 34 insulation This is the state before the resin injected to form the sealing material 4 hardens. In other words, the sliding movement of the movable member 6 is restricted after the insulating sealing material 4 is formed in the internal space 33 of the housing section 34 by the hardening of the resin. The movable member 6 may be fixed by fixing means to prevent sliding movement relative to the introduction section 32 when the resin is injected into the internal space 33 of the housing section 34, or it may be fixed by fixing means to the introduction section 32 after the resin has hardened. Alternatively, the sliding movement of the movable member 6 may be restricted by the formation of the solidified insulating sealing material 4 in the internal space 33 of the housing section 34 by the hardening of the resin.

[0027] The movable member 6 is placed in the internal space 3 3 By sliding it in this direction, the tip 22 of the high-voltage cable 2 can be moved further into the internal space 33 from its predetermined position (the position where the tip 22 is connected to the high-voltage terminal 5). 3 By sliding it away from the internal space 3, the tip 22 of the high-voltage cable 2 is moved into the internal space 3 3 It can be returned to the predetermined position described above.

[0028] The cross-sectional shape of the inner surface of the movable member 6 (a cross-section cut perpendicular to the longitudinal direction of the movable member 6) is, for example, circular, and the movable member 6 can accommodate the high-voltage cable 2. The movable member 6 is attached to the outer surface of the high-voltage cable 2 when the high-voltage cable 2 is fitted into it. The shape and size of the cross-sectional shape of the inner surface of the movable member 6 substantially match the shape and size of the cross-sectional shape of the outer surface of the high-voltage cable 2, so that the high-voltage cable 2 fits almost snugly inside the movable member 6, and the outer surface of the high-voltage cable 2 is in contact with the inner surface of the movable member 6. The high-voltage cable 2 is introduced into the housing section 34 from the introduction section 32 with the movable member 6 attached to its outer surface.

[0029] It is preferable that the space between the high-voltage cable 2 and the movable member 6 be liquid-tight. A "liquid-tight structure" means a structure in which the liquid (or gel-like) resin injected into the internal space 33 of the housing 34 does not leak out of the housing 3 through the space between the high-voltage cable 2 and the movable member 6. For example, if the sheathing portion 21 of the high-voltage cable 2 is made of rubber or the like, and the high-voltage cable 2 is fitted into the movable member 6 with the sheathing portion 21 compressed, a sealed, liquid-tight structure is created between the high-voltage cable 2 and the movable member 6, and leakage of the liquid resin can be suppressed.

[0030] The movable member 6 slides relative to the introduction section 32 as its outer surface comes into contact with the inner surface of the introduction section 32. As a result, the movable member 6 is guided by the introduction section 32 and can move in a straight line inside the introduction section 32.

[0031] The material of the movable member 6 can be metal. Because metal has high sliding properties and high wear resistance, making the movable member 6 out of metal allows it to slide smoothly inside the metal introduction section 32. Alternatively, the material of the movable member 6 can be a resin with high sliding properties. Resins with high sliding properties include, for example, fluororesins such as polytetrafluoroethylene, polyamide resins such as ultra-high molecular weight polyethylene and MC nylon, self-lubricating resins such as polyethylene terephthalate, PEEK (polyetheretherketone) resin, polyimide resin, and polyacetal resin. Making the movable member 6 out of a resin with high sliding properties also allows it to slide smoothly inside the metal introduction section 32. When making the movable member 6 out of resin, it is preferable to use a resin with excellent wear resistance.

[0032] It is preferable that a lubricant be interposed between the movable member 6 and the introduction portion 32. Conventional lubricants such as lubricating oils and greases can be used. By interposing a lubricant between the movable member 6 and the introduction portion 32, wear between the movable member 6 and the introduction portion 32 when the movable member 6 slides can be suppressed, and the sliding movement of the movable member 6 relative to the introduction portion 32 can be made smoother.

[0033] Preferably, at the end face of the movable member 6 opposite to the internal space 33 of the housing 34 (the end face into which the high-voltage cable 2 is inserted), the gap between the movable member 6 and the introduction section 32 is sealed with a sealant such as putty. This prevents the liquid (or gel-like) resin injected into the internal space 33 of the housing 34 from leaking out of the housing 3 through the gap between the introduction section 32 and the movable member 6.

[0034] The length of the movable member 6 is not particularly limited, but it is preferably such that it extends along the entire length of the introduction section 32. This has the effect of improving the workability of positioning.

[0035] Instructions on how to apply the medication. As shown in Figures 3 to 5, before the resin is injected into the internal space 33 of the housing 34 described above, agents 7 and 8 are applied to the inner surfaces of the housing 34 (side walls 31 and bottom 30) of the housing 3 and to the outer surface of the tip 22 of the high-voltage cable 2 housed in the internal space 33 of the housing 34. Agent 7 is applied to the inner surface of the housing 34, for example, to prevent the resin injected into the internal space 33 from adhering to the housing 34 once it hardens. On the other hand, agent 8 is applied to the outer surface of the tip 22 of the high-voltage cable 2, for example, to assist in the adhesion of the resin injected into the internal space 33 of the housing 34 to the tip 22 of the high-voltage cable 2 once it hardens. Note that agents 7 and 8 are not limited to agents having the functions described above.

[0036] In the application of the aforementioned drugs 7 and 8, first, as shown in Figure 3, the movable member 6 is slid relative to the introduction section 32 in a direction that approaches the internal space 33 of the housing section 34. This causes the tip 22 of the high-voltage cable 2 to enter the internal space 33 from a predetermined position to a position far away from the inner surface of the side wall 31. At this time, a portion of the movable member 6 protrudes from the introduction section 32 into the internal space 33 of the housing section 34 and is exposed, while the other portion remains inside the introduction section 32.

[0037] With the tip 22 of the high-voltage cable 2 temporarily placed at a position far away from the inner surface of the side wall 31, the chemical agent 7 is applied to the inner surface of the housing 34 using, for example, a brush, spatula, etc., as shown in Figure 4. In addition, a different type of chemical agent 8 is applied to the outer surface of the tip 22 of the high-voltage cable 2 using, for example, a brush, spatula, etc.

[0038] Once the application of agents 7 and 8 is complete, as shown in Figure 5, the movable member 6 is slid away from the internal space 33 of the housing 34 in order to return the tip 22 of the high-voltage cable 2 to its predetermined position in the internal space 33. At this time, the movable member 6 is retracted into the inside of the introduction section 32. This makes it possible to connect the tip 22 of the high-voltage cable 2 to the high-voltage terminal 5.

[0039] In this way, when applying the agents 7 and 8 to the inner surface of the housing section 34 and the outer surface of the tip 22 of the high-voltage cable 2, respectively, the tip 22 of the high-voltage cable 2 is moved from a position close to the inner surface of the side wall section 31 to a position far away from the inner surface of the side wall section 31, so that the outer surface of the tip 22 of the high-voltage cable 2 and the inner surface of the housing section 34 do not come into close contact. As a result, different types of agents 7 and 8 can be appropriately applied to the inner surface of the housing section 34 and the outer surface of the tip 22 of the high-voltage cable 2, thereby preventing agent 7 from adhering to the outer surface of the tip 22 of the high-voltage cable 2 when agent 7 is applied to the inner surface of the housing section 34, and preventing agent 8 from adhering to the inner surface of the housing section 34 when agent 8 is applied to the outer surface of the tip 22 of the high-voltage cable 2. Thus, it is possible to prevent unintended adhesion of agents to the inner surface of the housing section 34 and the outer surface of the tip 22 of the high-voltage cable 2, and to reduce the possibility of molding defects (resin sealing defects) of the insulating sealing material 4.

[0040] Furthermore, the chemicals may be applied to the inner surface of the housing section 34 by only one type of chemical 7, or to the outer surface of the tip 22 of the high-voltage cable 2 by only one type of chemical 8. In this case as well, it is possible to prevent unintended chemicals from adhering to the inner surface of the housing section 34 and the outer surface of the tip 22 of the high-voltage cable 2.

[0041] Action / Effect In the high-voltage cable connector 1 of this embodiment described above, a movable member 6 attached to the outer surface of the high-voltage cable 2 is provided inside the introduction section 32 so as to be slidable in a direction toward and toward the internal space 33 of the housing section 34. By sliding the movable member 6, the tip 22 of the high-voltage cable 2 can be further advanced into the internal space 33 of the housing section 34 from a predetermined position. As a result, the outer surface of the tip 22 of the high-voltage cable 2 is farther away from the inner surface of the housing section 34, so when applying different chemicals to the outer surface of the tip 22 of the high-voltage cable 2 and the inner surface of the housing section 34, the application range of each chemical can be clearly distinguished by sight, thereby improving the efficiency of the application work. Furthermore, since the outer surface of the tip 22 of the high-voltage cable 2 and the inner surface of the housing section 34 are not in close proximity, different types of chemicals 7 and 8 can be appropriately applied to the inner surface of the housing section 34 and the outer surface of the tip 22 of the high-voltage cable 2.

[0042] Furthermore, according to the high-voltage cable connector 1 of this embodiment, the movable member 6 is cylindrical and the high-voltage cable 2 is fitted into the movable member 6, so the movable member 6 can be slidably moved relative to the introduction part 32 with a simple structure, and the tip 22 of the high-voltage cable 2 can be moved within the internal space 33 of the housing part 34.

[0043] Furthermore, according to the high-voltage cable connector 1 of this embodiment, since a lubricant is interposed between the introduction portion 32 and the movable member 6, wear between the movable member 6 and the introduction portion 32 when the movable member 6 slides can be suppressed, and the sliding movement of the movable member 6 relative to the introduction portion 32 can be made smooth.

[0044] Explanation of variations While embodiments of the high-voltage cable connector and the method for applying a chemical agent to the high-voltage cable connector of the present invention have been described above, the high-voltage cable connector and the method for applying a chemical agent to the high-voltage cable connector of the present invention are not limited to the embodiments described above, and various modifications are possible without departing from the spirit of this disclosure.

[0045] For example, as a modified example, a stopper mechanism can be provided between the high-voltage cable 2 and the movable member 6 to stop the sliding movement of the movable member 6. The stopper mechanism can consist of, for example, as shown in Figures 6 and 7, at least one fitting projection 60 provided on the outer surface of the movable member 6 and at least one fitting groove 320 formed on the inner surface of the introduction section 32. The number of fitting projections 60 and the number of fitting grooves 320 are the same. When multiple fitting projections 60 are provided on the outer surface of the movable member 6, the multiple fitting projections 60 are provided on the outer surface of the movable member 6 at circumferential intervals. Introduction section 3 2 When multiple fitting grooves 320 are formed on the inner surface, the multiple fitting grooves 320 are located in the introduction section 3 2 They are provided on the inner surface at circumferential intervals.

[0046] The fitting projection 60 protrudes from the outer surface of the movable member 6 to a predetermined height and extends for a predetermined length along the longitudinal direction of the movable member 6. The fitting groove 320 is recessed into the inner surface of the introduction portion 32 to a depth approximately the same as the height of the fitting projection 60 and extends for a predetermined length along the longitudinal direction of the introduction portion 32. The length of the fitting groove 320 is sufficiently greater than the length of the fitting projection 60.

[0047] As shown in Figure 8(A), the tip 22 of the high-voltage cable 2 is inside the internal space 3 of the housing 34. 3When the movable member 6 is in the predetermined position described above, the fitting projection 60 of the movable member 6 is fitted into the fitting groove 320 of the introduction section 32 at the end opposite to the internal space 33. As shown in Figure 8(B), when the movable member 6 is slid in the direction toward the internal space 33 of the housing section 34, the fitting projection 60 moves within the fitting groove 320 and then abuts against the end of the fitting groove 320 on the internal space 33 side. This restricts further sliding of the movable member 6 and prevents the tip 22 of the high-voltage cable 2 from entering the internal space 33. Also, when the movable member 6 is slid away from the internal space 33 of the housing section 34 from the state shown in Figure 8(B), the fitting projection 60 moves within the fitting groove 320 and then abuts against the end of the fitting groove 320 on the opposite side of the internal space 33. This restricts further sliding of the movable member 6 and stops the tip 22 of the high-voltage cable 2 at the predetermined position in the internal space 33 described above.

[0048] Furthermore, the structure of the stopper mechanism is not limited to the structure described above; various known structures can be adopted as long as the sliding movement of the movable member 6 can be stopped at the appropriate position described above.

[0049] Furthermore, in the above embodiment, the movable member 6 is cylindrical, and the high-voltage cable 2 is fitted into the movable member 6. As a modified example, the movable member 6 may be plate-shaped, and a plurality of plate-shaped movable members 6 may be attached to the outer surface of the high-voltage cable 2 at circumferential intervals. In this modified example, by bringing the outer surfaces of the plurality of movable members 6 into contact with the inner surface of the introduction portion 32, the plurality of movable members 6 can slide relative to the introduction portion 32, thereby allowing the tip portion 22 of the high-voltage cable 2 to move within the internal space 33 of the housing portion 34.

[0050] Furthermore, in the above embodiment, the outer surface of the movable member 6 is brought into contact with the inner surface of the introduction portion 32, and the movable member 6 is slid relative to the introduction portion 32.
