Abstract
Description
[Technical Field]
[0001] The present invention relates to electrical connectors. [Background technology]
[0002] In some cases, on-site workers connect cables to electrical connectors, but because the outer diameter of the cable varies depending on factors such as the number of core wires, it has been necessary to prepare electrical connectors according to the outer diameter of the cable. Therefore, a clamp-type electrical connector that can be connected regardless of the outer diameter of the cable has been proposed (see, for example, Patent Document 1). In the electrical connector described in Patent Document 1, the cable is caught from above and below by the tabs of the fixed cover and the movable cover. The cable is clamped between the fixed cover and the movable cover, allowing it to be easily connected to the electrical connector. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Japanese Patent Publication No. 2020-027757 Summary of the Invention [Problem to be solved by the invention]
[0004] Although a tool such as pliers is required to connect a cable to the electrical connector described in Patent Document 1, it would be desirable to be able to connect a cable to the electrical connector using a more general-purpose tool.
[0005] The present invention has been made in consideration of these points, and aims to provide an electrical connector that allows cables to be easily wired using more general-purpose tools, even if the outer diameter size of the cable changes. [Means for solving the problem]
[0006] An electrical connector of one embodiment of the present invention is an electrical connector to which a cable is connected, and comprises a first cover that covers the outer surface of the cable from one side, a second cover that covers the outer surface of the cable from the other side, and a swing clamper connected to the second cover and facing the first cover, wherein the swing clamper approaches the first cover to clamp the cable between the swing clamper and the first cover, and a hook portion is formed on the swing clamper that can hook the tip of a tool, and the hook portion accepts swing operations on the swing clamper. [Effects of the Invention]
[0007] In the electrical connector of one aspect of the present invention, even if the outer diameter size of the cable changes, the swing clamper approaches the first cover and the cable is clamped between the swing clamper and the first cover. Furthermore, because the swing clamper is formed with a hook, it is possible to connect the cable to the electrical connector by using a more general-purpose tool to bring the swing clamper close to the first cover without using pliers or the like.

In the following description, the first cover side will be referred to as the lower side of the electrical connector, the second cover side will be referred to as the upper side of the electrical connector, the leading end side in the cable insertion direction will be referred to as the front side of the electrical connector, and the rear end side in the cable insertion direction will be referred to as the rear side of the electrical connector. In each figure, the lower side of the electrical connector will be indicated by arrow LO, the upper side by arrow U, the front side by arrow FR, the rear side by arrow RE, the left side by arrow L, and the right side by arrow R.
[0010] As shown in Figures 1 and 2, the electrical connector 1 is a cable connector to which a cable 2, such as a shielded multi-core cable, is connected. The electrical connector 1 accommodates the end of the cable 2 with a first cover 10 and a second cover 20. The first cover 10 covers the outer surface of the cable 2 from below, and the second cover 20 covers the outer surface of the cable 2 from above. A housing 5 is accommodated in front of the first and second covers 10, 20, and an end of the cable 2 is connected to the housing 5. A plug 6 is provided on the front of the housing 5, and protrudes forward from the first and second covers 10, 20.
[0011] The second cover 20 is formed shorter than the first cover 10 in the insertion direction of the cable 2, and the rear end of the second cover 20 is located forward of the rear end of the first cover 10. A swing clamper 30 is connected to the rear of the second cover 20 so as to be swingable in the vertical direction, and the swing clamper 30 faces the first cover 10 with the cable 2 sandwiched between them. The swing clamper 30 approaches the first cover 10, and the cable 2 is clamped from above and below by the swing clamper 30 and the first cover 10. A hook portion 35 for a tool is formed on the outer surface of the swing clamper 30, and the hook portion 35 accepts a swing operation for the swing clamper 30.
[0012] A hooking member 40 is installed at the rear of the first cover 10, and the swing clamper 30 is hooked by the hooking member 40. A pair of ratchet arms 33 protrude from both left and right ends of the swing clamper 30 toward the hooking member 40, and a pair of hooking arms 46 protrude from both left and right ends of the hooking member 40 toward the swing clamper 30. A plurality of ratchet teeth 34 are formed on the pair of ratchet arms 33, and a hooking pawl 47 is formed on the pair of hooking arms 46. The plurality of ratchet teeth 34 protrude forward from the ratchet arm 33, and the hooking pawl 47 protrudes rearward from the hooking arm 46. The ratchet teeth 34 and the hooking pawl 47 form a ratchet mechanism that swings the swing clamper 30 only downward.
[0013] The first cover 10 and the second cover 20 are connected to each other via the housing 5 on the front side of the electrical connector 1 so as to be able to open and close. A pair of retaining arms 44 protrude upward from both left and right ends of the latching member 40, and the rear ends of both side walls 21 of the second cover 20 protrude partially rearward. Retaining claws 45 are formed on the pair of retaining arms 44, and claw receivers 26 are formed by protruding portions on both side walls 21 of the second cover 20. The retaining claws 45 and the claw receivers 26 are snap-fitted together, and the elastic force of the retaining arms 44 is used to mechanically connect the first cover 10 and the second cover 20.
[0014] As shown in FIG. 3, the first cover 10 is a die-cast product and has a pair of side walls 11 and a bottom wall 12. The front portions of the pair of side walls 11 extend further forward than the bottom wall 12, and swing shafts 13 protrude from the inner surfaces of the front portions of the pair of side walls 11. The pair of swing shafts 13 are inserted into shaft holes in the housing 5 (see FIG. 2), and the first cover 10 is attached to the housing 5 so as to be able to open downward. Parts of the rear portions of the pair of side walls 11 are cut out in a concave shape, and the pair of cutouts 14 make the upper edges of the pair of side walls 11 one step lower. The upper edges of the pair of side walls 11 are higher behind the pair of cutouts 14, forming high wall portions 15.
[0015] A pair of support pillars 16 protrude from the inner bottom surface of the bottom wall 12 on the inside of the pair of cutouts 14 in the left-right direction. As will be described in detail later, the tips of the pair of support pillars 16 support a pair of connecting shafts 31 of a swing clamper 30 (see FIG. 4) from below. A holding portion 17 that holds a hook member 40 is formed between the pair of support pillars 16. When the holding portion 17 is cut along a plane perpendicular to the left-right direction, the holding portion 17 is formed in an inverted L-shape in cross section, and the hook member 40 (see FIG. 5) is held inside the holding portion 17 so that it can slide in the front-rear direction. An opening 18 that partially exposes the hook member 40 is formed in the bottom wall 12 below the holding portion 17, and the sliding operation of the hook member 40 is accepted through the opening 18 (see FIG. 6 in particular).
[0016] As shown in FIG. 4, the second cover 20 is a die-cast product and has a pair of side walls 21 and an upper wall 22. The front portions of the pair of side walls 21 extend further forward than the upper wall 22, and swing shafts 24 protrude from the inner surfaces of the front portions of the pair of side walls 21. The pair of swing shafts 24 are inserted into shaft holes in the housing 5 (see FIG. 2), and the second cover 20 is attached to the housing 5 in an upwardly openable manner. Parts of the rear portions of the pair of side walls 21 protrude downward, and the pair of protruding portions 25 lower the lower edges of the pair of side walls 21 by one step. When the first and second covers 10 and 20 are closed, the pair of protruding portions 25 fit into the pair of cutouts 14 (see FIG. 1).
[0017] The rear ends of the pair of overhanging portions 25 protrude rearward to form a pair of claw receivers 26. When the overhanging portions 25 fit into the notches 14, a gap is formed between the claw receivers 26 of the second cover 20 and the high wall portion 15 of the first cover 10, into which the retaining claws 45 of the hooking member 40 fit (see FIG. 1). A pair of restricting protrusions 27 protrude from the inner top surface of the upper wall 22 toward the bottom wall 12 (see FIG. 3). As will be described in detail later, the pair of restricting protrusions 27 abut against the front ends of the hooking members 40, thereby restricting the forward sliding of the hooking members 40 (see FIG. 8(B)). The corners of the pair of restricting protrusions 27 facing the hooking members 40 are chamfered to prevent interference between the pair of restricting protrusions 27 and the hooking members 40.
[0018] Slotted holes 29 are formed in the rear portions of the pair of side walls 21, and a pair of connecting shafts 31 are formed in the front portion of the swing clamper 30. The pair of connecting shafts 31 are inserted into the pair of slotted holes 29, and the swing clamper 30 is swingably connected to the second cover 20. The pair of slotted holes 29 extend in the vertical direction, and the relative positional relationship between the second cover 20 and the swing clamper 30 changes when the pair of connecting shafts 31 are moved along the pair of slotted holes 29. This prevents the swing clamper 30 from moving along with the opening and closing operation of the second cover 20, and allows the second cover 20 to be opened while the cable 2 is clamped by the swing clamper 30 (see FIG. 9(A)).
[0019] The swing clamper 30 is a die-cast product and is installed so as to face the first cover 10. A pair of connecting shafts 31 are formed on both left and right ends of the front end of the swing clamper 30, and the swing clamper 30 swings around the pair of connecting shafts 31 as fulcrums. A sharp-pointed convex portion 32 protrudes downward from the rear end (tip) of the swing clamper 30. The sharp-pointed convex portion 32 of the swing clamper 30 bites into the outer peripheral surface of the cable 2, and the cable 2 is tightly clamped by the swing clamper 30 and the first cover 10. A pair of ratchet arms 33 protrude downward from both left and right ends of the sharp-pointed convex portion 32, and each ratchet arm 33 has two ratchet teeth 34 formed thereon.
[0020] A hook-shaped hook portion 35 protrudes from the outer surface of the swing clamper 30, and the hook portion 35 extends linearly from the left end to the right end (see FIG. 1 in particular). The tip of a tool such as a flathead screwdriver is hooked onto the hook-shaped hook portion 35 to open or close the swing clamper 30. A pair of positioning portions 36 protrudes from the outer surface of the swing clamper 30 behind the hook portion 35. The pair of positioning portions 36 are provided to avoid the center portion of the swing clamper 30 in the left-right direction, and a tool is inserted between the pair of positioning portions 36 to position the tool relative to the swing clamper 30. Left-right misalignment between the hook portion 35 and the tool is suppressed, making it difficult for the tool to come off the hook portion 35.
[0021] 5(A) and 5(B), the hooking member 40 is molded from synthetic resin. A pair of base portions 41 of the hooking member 40 extends forward and backward, and the pair of base portions 41 are connected via front and rear bridges 42, 43. The corners of the front ends of the pair of base portions 41 are chamfered, and these chamfered surfaces 48 are formed to be able to come into surface contact with the chamfered surfaces 28 of the pair of restricting protrusions 27. Retaining arms 44 protrude upward from the front portions of the pair of base portions 41, and retaining claws 45 are formed at the tips of the pair of retaining arms 44. Retaining arms 46 protrude diagonally upward and rearward from the center of the pair of base portions 41, and retaining claws 47 are formed at the tips of the pair of retaining arms 46.
[0022] As shown in Figures 5 and 6, the front and rear bridges 42, 43 are inserted from the rear into the gap between the bottom wall 12 and the holding portion 17 of the first cover 10. As will be described in detail later, the latching member 40 is slidable in a direction that moves the latching pawl 47 away from the ratchet teeth 34. The front bridge 42 is exposed from the opening 18 in the bottom wall 12, and receives a sliding operation from outside through the opening 18. The rear bridge 43 is formed with a linear protrusion 49 that fits into the opening 18. When the linear protrusion 49 comes into contact with the edge of the opening, the latching member 40 is positioned at a rear position P2 (see Figure 8(B)) where the latching pawl 47 can engage with the ratchet teeth 34.
[0023] The clamping state of a cable by an electrical connector will be described with reference to Fig. 7. Fig. 7 shows a side view and a cross-sectional view of the electrical connector of this embodiment. Fig. 7(A) is a side view of the electrical connector. Fig. 7(B) is a cross-sectional view of the electrical connector of Fig. 7(A) taken along line AA. Fig. 7(C) is a cross-sectional view of the electrical connector of Fig. 7(A) taken along line BB.
[0024] As shown in Figure 7(A), when the cable 2 is clamped by the swing clamper 30, the latching claws 47 of the latching member 40 engage with the ratchet teeth 34 of the swing clamper 30. The ratchet teeth 34 are latched onto the latching claws 47, preventing the swing clamper 30 from swinging upward and restricting release of the clamp. The clamped state of the cable 2 is maintained, preventing the cable 2 from being removed from the electrical connector 1. At this time, the restricting projections 27 of the second cover 20 restrict the forward sliding of the latching member 40, preventing the latching claws 47 from separating from the ratchet teeth 34.
[0025] The swing clamper 30 is formed with two ratchet teeth 34, one on top and one on bottom, and the latching pawl 47 engages with either of the ratchet teeth 34, allowing the clamping position of the swing clamper 30 to be adjusted in two stages. When clamping a relatively thin cable 2 as shown in FIG. 7(A), the upper ratchet tooth 34 is latched onto the latching pawl 47, and when clamping a relatively thick cable (not shown), the lower ratchet tooth 34 is latched onto the latching pawl 47. In this way, by forming a plurality of ratchet teeth 34 on the swing clamper 30, it is possible to clamp cables of different outer diameters.
[0026] As shown in Figures 7(A) and (B), the connecting shaft 31 of the swing clamper 30 is inserted into the elongated hole 29 of the second cover 20. At this time, inside the second cover 20, the connecting shaft 31 is supported from below by the support pillar 16 of the first cover 10, and the connecting shaft 31 is sandwiched from above and below by the upper end of the support pillar 16 and the upper edge of the elongated hole 29. As shown in Figures 7(A) and (C), when the first cover 10 and the second cover 20 are closed, the retaining claw 45 of the hooking member 40 is inserted from the inside into the gap between the claw receiver 26 of the second cover 20 and the high wall portion 15 of the first cover 10. As a result, the retaining claw 45 is snap-fitted to the claw receiver 26 of the second cover 20.
[0027] The clamping operation and the clamping release operation of the electrical connector will be described with reference to Figures 8 and 9. Figure 8 is a transition diagram of the clamping operation of the electrical connector of this embodiment. Figure 9 is a transition diagram of the clamping release operation of the electrical connector of this embodiment.
[0028] As shown in FIG. 8(A), before the clamping operation by the electrical connector 1, the second cover 20 is open relative to the first cover 10. At this time, the restricting protrusion 27 of the second cover 20 is separated from the bottom wall 12 of the first cover 10. The latching member 40 is located at the front position P1, and the chamfered surface 28 of the restricting protrusion 27 is supported from below by the chamfered surface 48 of the latching member 40. Because the second cover 20 is open, the pawl receiver 26 of the second cover 20 is located above the holding pawl 45 of the latching member 40. Because the latching member 40 is located at the front position P1, the latching pawl 47 of the latching member 40 is separated rearward from the ratchet teeth 34 of the swing clamper 30.
[0029] As shown in FIG. 8(B), when the second cover 20 is closed relative to the first cover 10, the restricting protrusion 27 of the second cover 20 is pushed toward the bottom wall 12 of the first cover 10. Because the chamfered surfaces 48, 28 of the hooking member 40 and the restricting protrusion 27 are in contact at an angle, the pushing action of the restricting protrusion 27 causes the hooking member 40 to slide rearward. The linear protrusion 49 (see FIG. 6) of the hooking member 40 abuts against the edge of the opening (the rear edge of the opening 18) of the first cover 10, and the hooking member 40 is positioned at the rear position P2. Then, with the first cover 10 and the second cover 20 closed, the retaining claw 45 of the hooking member 40 is snap-fitted into the claw receiver 26 of the second cover 20.
[0030] 8(C), the tip of a flat-head screwdriver 50 is hooked on the hook-shaped catch 35 of the swinging clamper 30, and the swinging clamper 30 is pushed down by the flat-head screwdriver 50. The swinging clamper 30 is brought close to the first cover 10, and the cable 2 is clamped from above and below by the swinging clamper 30 and the first cover 10. The latching claw 47 of the latching member 40 engages with the ratchet teeth 34 of the swinging clamper 30, preventing the clamp from being released. At this time, the sliding of the latching member 40 is restricted by the restricting protrusion 27, so the latching claw 47 does not separate from the ratchet teeth 34, preventing the cable 2 from being disconnected from the electrical connector 1.
[0031] As shown in Figure 9(A), when releasing the clamp by the electrical connector 1, the snap-fit connection between the holding claws 45 of the hooking member 40 and the claw receivers 26 of the second cover 20 is released by a flat-head screwdriver 50 (see Figure 8(C)). Since the second cover 20 and the swing clamper 30 are connected via the elongated holes 29, when the second cover 20 is opened relative to the first cover 10, only the second cover 20 is moved with the swing clamper 30 hooked to the hooking member 40. At this time, the restricting protrusions 27 of the second cover 20 are separated from the bottom wall 12 of the first cover 10, and the sliding restriction of the hooking member 40 by the restricting protrusions 27 is released.
[0032] As shown in FIG. 9(B), a flat-head screwdriver 50 is inserted through the opening 18 (see FIG. 6) of the first cover 10, and the latching member 40 is slid forward by the flat-head screwdriver 50. At this time, the latching member 40 is positioned at the forward position P1, the latching pawl 47 is released from the ratchet teeth 34, and the clamping of the cable 2 is released. Then, as shown in FIG. 9(C), the tip of the flat-head screwdriver 50 is hooked on the hook portion 35 of the swing clamper 30, and the swing clamper 30 is lifted up by the flat-head screwdriver 50. In this manner, the cable 2 is removed from the electrical connector 1.
[0033] As described above, according to this embodiment, even if the outer diameter size of the cable 2 changes, the swing clamper 30 approaches the first cover 10, and the cable 2 is clamped between the swing clamper 30 and the first cover 10. Furthermore, because the swing clamper 30 is formed with the hook portion 35, it is possible to connect the cable 2 to the electrical connector 1 by using a more general-purpose tool, without using pliers or the like. In particular, in this embodiment, it is possible to connect the cable 2 to the electrical connector 1 and remove the cable 2 from the electrical connector 1 with just one flat-head screwdriver 50.
[0034] In the electrical connector of this embodiment, the ratchet arm of the swing clamper has a plurality of ratchet teeth, but the number of ratchet teeth on the ratchet arm is not particularly limited. The ratchet arm may have one ratchet tooth, or three or more ratchet teeth.
[0035] In addition, in the electrical connector of this embodiment, the first and second covers are held in a closed state by a snap-fit connection, but the first and second covers may also be held in a closed state by a connection method other than a snap-fit connection.
[0036] In addition, in the electrical connector of this embodiment, the regulating protrusion of the second cover contacts the front end of the latching member to regulate the sliding of the latching member, but the regulating protrusion may also contact a part of the latching member other than the front end to regulate the sliding of the latching member.
[0037] In addition, in the electrical connector of this embodiment, an opening is formed in the first cover to partially expose the latching member, but the first cover does not need to have an opening formed therein as long as the latching member can be slid.
[0038] In addition, in the electrical connector of this embodiment, a latching member is inserted into the gap between the holding portion and the bottom wall of the first cover, but the method of installing the latching member is not limited as long as the latching member is installed so as to be slidable relative to the first cover.
[0039] Furthermore, in the electrical connector of this embodiment, the clamping and unclamping operations are performed using a flathead screwdriver as a tool, but the clamping and unclamping operations may also be performed using a long tool such as a Phillips screwdriver.
[0040] In addition, although the hook portion of the electrical connector of this embodiment is formed in a hook shape, the hook portion may be formed in any shape as long as the shape allows a tool to be hooked onto the swing clamper. For example, the hook portion may be formed by a groove provided in the swing clamper.
[0041] Furthermore, in the electrical connector of this embodiment, the positioning portion is formed on the swing clamper, but the swing clamper does not necessarily have to have the positioning portion formed thereon.
[0042] As described above, the electrical connector (1) of this embodiment is an electrical connector to which a cable (2) is connected, and includes a first cover (10) that covers the outer surface of the cable from one side (lower side), a second cover (20) that covers the outer surface of the cable from the other side (upper side), and a swing clamper (30) that is connected to the second cover and faces the first cover. When the swing clamper approaches the first cover, the cable is clamped between the swing clamper and the first cover. The swing clamper has a hook portion (35) that can hook the tip of a tool (flathead screwdriver 50), and this hook portion accepts a swing operation for the swing clamper. With this configuration, even if the outer diameter size of the cable changes, the swing clamper approaches the first cover and the cable is clamped between the swing clamper and the first cover. Furthermore, since the swing clamper is formed with a hook portion, it is possible to use a more general-purpose tool to move the swing clamper closer to the first cover and connect the cable to the electrical connector without using pliers or the like.
[0043] In the electrical connector of this embodiment, the hook portion protrudes from the outer surface of the swing clamper in a hook-like shape. With this configuration, the tip of a tool can be hooked onto the hook-shaped hook portion to operate the swing clamper.
[0044] In the electrical connector of this embodiment, the swing clamper is formed with a positioning portion (36) that positions the tool in the width direction (left and right direction). This configuration reduces misalignment between the hook portion of the swing clamper and the tool in the width direction, making it difficult for the tool to come off the hook portion.
[0045] The electrical connector of this embodiment includes a latching member (40) that is installed on the first cover and latches a swinging clamper, with ratchet teeth (34) formed on the swinging clamper and a latching pawl (47) formed on the latching member. When the cable is clamped, the latching pawl engages with the ratchet teeth to prevent release of the clamp, and the latching member is slidable in a direction that separates the latching pawl from the ratchet teeth. With this configuration, when the cable is clamped, the latching pawl engages with the ratchet teeth to prevent release of the clamp, preventing the cable from being removed from the electrical connector. Furthermore, by sliding the latching member, the latching pawl is separated from the ratchet teeth, allowing release of the cable clamp, and the swinging clamper is separated from the first cover, allowing the cable to be easily removed from the electrical connector.
[0046] In the electrical connector of this embodiment, a retaining claw (45) is formed on the latching member, a claw receiver (26) is formed on the second cover, the first cover and the second cover are connected to each other so as to be able to open and close at the tip end (front side) in the cable insertion direction, and when the first cover and the second cover are closed, the retaining claw is snap-fitted to the claw receiver. This configuration allows the first cover and the second cover to be mechanically connected. Also, the second cover can be easily opened from the first cover.
[0047] In the electrical connector of this embodiment, a restricting protrusion (27) protrudes from the second cover toward the first cover, and when the first and second covers are closed, the restricting protrusion restricts the sliding of the latching member, and when the first and second covers are open, the restriction on the sliding of the latching member by the restricting protrusion is released. With this configuration, when the first and second covers are closed, the restricting protrusion restricts the sliding of the latching member, so the latching pawl does not separate from the ratchet teeth, preventing the cable from being disconnected from the electrical connector. When the second cover is opened from the first cover, the restriction on the sliding of the latching member is released, so the latching pawl separates from the ratchet teeth, allowing the cable to be easily disconnected from the electrical connector.
[0048] In the electrical connector of this embodiment, an elongated hole (29) is formed in the second cover, a connecting shaft (31) is formed in the swing clamper, the connecting shaft is inserted into the elongated hole to connect the swing clamper to the second cover, the elongated hole extends in the direction in which the first cover and the second cover face each other (up and down), and the connecting shaft moves along the elongated hole to change the relative positional relationship between the second cover and the swing clamper. With this configuration, the second cover can be opened from the first cover while the cable is clamped by the swing clamper.
[0049] In the electrical connector of this embodiment, an opening (18) is formed in the first cover to partially expose the latching member, and the latching member can be slid through the opening. With this configuration, the latching member can be slid through the opening to easily remove the cable from the electrical connector.
