Description

Electric connector

Technical Field

The present invention relates to an electrical connector.

Background

There are cases where the cable and the electrical connector are wired by a worker in the field, but the outer diameter size of the cable varies depending on the number of core wires or the like, and therefore the electrical connector must be prepared depending on the outer diameter size of the cable. Therefore, a clamp-type electrical connector capable of performing connection without taking into consideration the outer diameter of the cable has been proposed (for example, refer to patent document 1). In the electrical connector described in patent document 1, the claw of the fixed cover and the claw of the movable cover bite into the cable from above and below. The cable is clamped between the fixed cover and the movable cover to easily wire the cable with the electrical connector.

Patent document 1: japanese patent laid-open No. 2020-027757

In order to wire a cable with the electrical connector described in patent document 1, a tool such as pliers is required, but it is desirable to be able to wire a cable with an electrical connector using a more general-purpose tool.

Disclosure of Invention

The present invention has been made in view of the above-described points, and an object thereof is to provide an electrical connector capable of easily connecting cables using a more general-purpose tool even if the outer diameter dimension of the cables is changed.

An electrical connector according to an aspect of the present invention is an electrical connector for connecting a cable, comprising: a 1 st cover covering the outer peripheral surface of the cable from one side; a 2 nd cover covering the outer peripheral surface of the cable from the other side; and a swing clamp coupled to the 2 nd cover and facing the 1 st cover, wherein the swing clamp is brought close to the 1 st cover to clamp the cable by the swing clamp and the 1 st cover, and a hook portion capable of catching a tip of a tool is formed in the swing clamp, and a swing operation of the swing clamp is received by the hook portion.

In the electrical connector of one aspect of the present invention, even if the outer diameter dimension of the cable varies, the swing clamp is brought close to the 1 st cover to clamp the cable by the swing clamp and the 1 st cover. Further, since the swing clamp is formed with the hooking portion, the cable can be wired to the electrical connector by bringing the swing clamp and the 1 st cover close to each other without using pliers or the like and using a more general tool.

In the following description, the 1 st cover side is defined as the lower side of the electrical connector, the 2 nd cover side is defined as the upper side of the electrical connector, the front end side in the insertion direction of the cable is defined as the front side of the electrical connector, and the rear end side in the insertion direction of the cable is defined as the rear side of the electrical connector. In each drawing, the lower side of the electrical connector is indicated by an arrow LO, the upper side by an arrow U, the front side by an arrow FR, the rear side by an arrow RE, the left side by an arrow L, and the right side by an arrow R.

As shown in fig. 1 and 2, the electrical connector 1 is a cable connector for connecting a cable 2 such as a shielded multi-core cable. The electrical connector 1 receives the end of the cable 2 through the 1 st cover 10 and the 2 nd cover 20. The 1 st cover 10 covers the outer peripheral surface of the cable 2 from the lower side, and the 2 nd cover 20 covers the outer peripheral surface of the cable 2 from the upper side. The case 5 is housed in front of the 1 st and 2 nd covers 10 and 20, and the end of the cable 2 is connected to the case 5. A plug 6 is provided on the front surface of the housing 5, and the plug 6 protrudes forward from the 1 st and 2 nd covers 10 and 20.

The 2 nd cover 20 is formed shorter than the 1 st cover 10 in the insertion direction of the cable 2, and the rear end of the 2 nd cover 20 is located forward of the rear end of the 1 st cover 10. A swing clamp 30 is connected to the rear portion of the 2 nd cover 20 so as to be capable of swinging in the up-down direction, and the swing clamp 30 faces the 1 st cover 10 with the cable 2 interposed therebetween. The swing clamp 30 is close to the 1 st cover 10, and clamps the cable 2 from the up-down direction by the swing clamp 30 and the 1 st cover 10. A tool hook 35 is formed on the outer surface of the swing clamp 30, and the swing operation of the swing clamp 30 is received by the tool hook 35.

A locking member 40 is provided at the rear of the 1 st cover 10, and the swing clamp 30 is locked by the locking member 40. The pair of click arms 33 protrude from both ends of the swing clamp 30 in the left-right direction toward the locking member 40 side, and the pair of locking arms 46 protrude from both ends of the locking member 40 in the left-right direction toward the swing clamp 30 side. A plurality of ratchet teeth 34 are formed on the pair of pawl arms 33, and a locking claw 47 is formed on the pair of locking arms 46. The plurality of ratchet teeth 34 protrude forward from the pawl arm 33, and the locking pawl 47 protrudes rearward from the locking arm 46. The ratchet teeth 34 and the locking pawls 47 form a pawl mechanism that swings the swing clamp 30 only downward.

On the front side of the electrical connector 1, the 1 st cover 10 and the 2 nd cover 20 are openably and closably coupled via the housing 5. The pair of holding arms 44 protrude upward from both ends of the locking member 40 in the left-right direction, and the rear ends of both side walls 21 of the 2 nd cover 20 protrude rearward. The pair of holding arms 44 are formed with holding claws 45, and the two side walls 21 of the 2 nd cover 20 are formed with claw receiving portions 26 by protruding portions. The holding claw 45 is engaged with the claw receiving portion 26, and mechanically couples the 1 st cover 10 and the 2 nd cover 20 by the elastic force of the holding arm 44.

As shown in fig. 3, the 1 st cover 10 is a die-cast molding member having a pair of side walls 11 and a bottom wall 12. The front portions of the pair of side walls 11 extend forward of the bottom wall 12, and the swing shafts 13 protrude from the front inner surfaces of the pair of side walls 11. A pair of swing shafts 13 are inserted into shaft holes of the housing 5 (see fig. 2) to mount the 1 st cover 10 to the housing 5 so as to be openable downward. A part of the rear portions of the pair of side walls 11 is recessed, and the upper edges of the pair of side walls 11 are lowered by the pair of cutouts 14. The upper edges of the pair of side walls 11 are raised at the rear side of the pair of cutouts 14 to form a high wall portion 15.

A pair of support posts 16 protrude from the inner bottom surface of the bottom wall 12 at positions on the inner side in the lateral direction than the pair of cutouts 14. The pair of coupling shafts 31 of the swing clamp 30 (see fig. 4) are supported from below by the tips of the pair of support columns 16, and details thereof will be described later. A holding portion 17 for holding the locking member 40 is formed between the pair of support columns 16. When the holding portion 17 is cut by a plane orthogonal to the left-right direction, the holding portion 17 is formed in an inverted L shape in cross section, and the locking member 40 (see fig. 5) is held slidably in the front-rear direction inside the holding portion 17. An opening 18 is formed in the bottom wall 12 below the holding portion 17 to partially expose the locking member 40, and a sliding operation of the locking member 40 is received through the opening 18 (see fig. 6 in particular).

As shown in fig. 4, the 2 nd cover 20 is a die-cast molding member having a pair of side walls 21 and an upper wall 22. The front portions of the pair of side walls 21 extend forward of the upper wall 22, and the swing shaft 24 protrudes from the front inner surfaces of the pair of side walls 21. A pair of swing shafts 24 are inserted into shaft holes of the housing 5 (see fig. 2), and the 2 nd cover 20 is attached to the housing 5 so as to be opened upward. A part of the rear portions of the pair of side walls 21 protrudes downward, and the lower edges of the pair of side walls 21 are lowered by the pair of protruding portions 25. In the state where the 1 st and 2 nd covers 10 and 20 are closed, the pair of protruding portions 25 enter the pair of cutouts 14 (see fig. 1).

The rear ends of the pair of protruding portions 25 protrude rearward to form a pair of claw receiving portions 26. The protruding portion 25 is inserted into the notch 14, so that a slit into which the holding claw 45 of the locking member 40 is inserted is formed by the claw receiving portion 26 of the 2 nd cover 20 and the high wall portion 15 of the 1 st cover 10 (see fig. 1). A pair of restricting projections 27 project from the inner top surface of the upper wall 22 toward the bottom wall 12 (see fig. 3). The forward sliding of the locking member 40 is regulated by the abutment of the pair of regulating projections 27 with the distal ends of the locking member 40 (see fig. 8B), which will be described in detail later. The corners of the locking members 40 of the pair of restricting projections 27 are chamfered to avoid interference between the pair of restricting projections 27 and the locking members 40.

A long hole 29 is formed at the rear of the pair of side walls 21, and a pair of coupling shafts 31 is formed at the front of the swing clamp 30. The pair of coupling shafts 31 are inserted into the pair of elongated holes 29 to swingably couple the swing clamp 30 to the 2 nd cover 20. The pair of long holes 29 extend in the vertical direction, and the relative positional relationship between the 2 nd cover 20 and the swing clamp 30 is changed by moving the pair of coupling shafts 31 along the pair of long holes 29. Thus, the swing clamp 30 is not interlocked with the opening and closing operation of the 2 nd cover 20, and the 2 nd cover 20 can be opened in a state where the swing clamp 30 clamps the cable 2 (see fig. 9 a).

The swing clamp 30 is a die-cast molding member and is disposed opposite to the 1 st cover 10. A pair of coupling shafts 31 are formed at both ends of the tip portion of the swing clamp 30 in the lateral direction, and the swing clamp 30 swings with the pair of coupling shafts 31 as fulcrums. The sharp convex portion 32 protrudes downward from the rear end (front end) of the swing clamp 30. The sharp convex portions 32 of the swing clamp 30 bite into the outer peripheral surface of the cable 2, and the cable 2 is strongly clamped by the swing clamp 30 and the 1 st cover 10. A pair of pawl arms 33 protrude downward from both ends of the sharp convex portion 32 in the left-right direction, and two ratchet teeth 34 are formed on each pawl arm 33.

The hook-shaped hooking portion 35 protrudes from the outer surface of the swing clamp 30, and the hooking portion 35 extends linearly from the left end to the right end (refer to fig. 1 in particular). The front end of a tool such as a straight screwdriver is engaged with the hook 35 to open and close the swing clamp 30. A pair of positioning portions 36 protrude from the outer surface of the swing clamp 30 at positions on the rear side of the hooking portions 35. The pair of positioning portions 36 are provided so as to avoid the center portion of the swing clamp 30 in the lateral direction, and a tool is inserted between the pair of positioning portions 36 to position the tool with respect to the swing clamp 30. The deviation of the hooking portion 35 from the left-right direction of the tool is suppressed, and the tool is less likely to fall off from the hooking portion 35.

As shown in fig. 5 (a) and (B), the locking member 40 is molded from a synthetic resin. The pair of base portions 41 of the locking member 40 extend forward and backward, and the pair of base portions 41 are connected via the front and rear bridging members 42, 43. The corners of the distal ends of the pair of base portions 41 are chamfered, and the chamfer surfaces 48 are formed so as to be capable of surface-contacting with the chamfer surfaces 28 of the pair of restricting projections 27. The holding arms 44 protrude upward from the front portions of the pair of base portions 41, and holding claws 45 are formed at the front ends of the pair of holding arms 44. The locking arms 46 protrude obliquely rearward and upward from the central portions of the pair of base portions 41, and locking claws 47 are formed at the front ends of the pair of locking arms 46.

As shown in fig. 5 and 6, the front and rear bridging members 42, 43 are inserted into the gaps between the bottom wall 12 of the 1 st cover 10 and the holding portion 17 from behind. The locking member 40 is slidable in a direction to move the locking pawl 47 away from the ratchet teeth 34, which will be described in detail later. The bridge member 42 on the front side is exposed from the opening 18 of the bottom wall 12, and receives a sliding operation from the outside through the opening 18. A linear protrusion 49 is formed on the rear bridge member 43 so as to enter the opening 18. The linear convex portion 49 contacts the opening edge, so that the locking member 40 is positioned at a rear position P2 where the locking pawl 47 can engage with the ratchet teeth 34 (see fig. 8B).

The cable clamping state by the electrical connector will be described with reference to fig. 7. Fig. 7 is a side view and a cross-sectional view of the electrical connector of the present embodiment. Further, 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 A-A. Fig. 7 (C) is a cross-sectional view of the electrical connector of fig. 7 (a) taken along line B-B.

As shown in fig. 7 (a), in a state where the swing clamp 30 clamps the cable 2, the locking claw 47 of the locking member 40 is engaged with the ratchet teeth 34 of the swing clamp 30. By engaging the ratchet teeth 34 with the engaging pawls 47, the swing of the swing clamp 30 upward is prevented, and the release of the clamp is restricted. The clamped state of the cable 2 is maintained to prevent the cable 2 from coming off the electrical connector 1. At this time, the forward sliding of the locking member 40 is restricted by the restricting projection 27 of the 2 nd cover 20, and the locking pawl 47 does not come off the ratchet 34.

Further, the swing clamp 30 is formed with two upper and lower ratchet teeth 34, and the clamping position by the swing clamp 30 is adjusted to two stages by engaging the engagement pawl 47 with any one of the ratchet teeth 34. When the comparatively thin type cable 2 as shown in fig. 7 a is clamped, the upper ratchet 34 is engaged with the engagement pawl 47, and when the comparatively thick type cable (not shown) is clamped, the lower ratchet 34 is engaged with the engagement pawl 47. By forming the plurality of ratchet teeth 34 in the swing clamp 30 in this way, cables of the type having widely different outside diameter sizes can be clamped.

As shown in fig. 7 (a) and (B), the coupling shaft 31 of the swing clamp 30 is inserted into the long hole 29 of the 2 nd cover 20. At this time, the coupling shaft 31 is supported from below by the support column 16 of the 1 st cover 10 inside the 2 nd cover 20, and the coupling shaft 31 is sandwiched from above and below by the upper end of the support column 16 and the upper edge of the long hole 29. As shown in fig. 7 (a) and (C), in a state where the 1 st cover 10 and the 2 nd cover 20 are closed, the holding claws 45 of the locking member 40 enter the slit between the claw receiving portions 26 of the 2 nd cover 20 and the high wall portion 15 of the 1 st cover 10 from the inside. Thereby, the holding claw 45 is snap-engaged with the claw receiving portion 26 of the 2 nd cover 20.

The clamping operation and the clamping releasing operation by the electrical connector will be described with reference to fig. 8 and 9. Fig. 8 is a diagram showing a change in the clamping operation of the electrical connector according to the present embodiment. Fig. 9 is a variation of the clamping releasing operation of the electric connector according to the present embodiment.

As shown in fig. 8 (a), the 2 nd cover 20 is opened with respect to the 1 st cover 10 before the clamping action based on the electrical connector 1. At this time, the restricting projection 27 of the 2 nd cover 20 is disengaged from the bottom wall 12 of the 1 st cover 10. The locking member 40 is positioned at the front position P1, and the chamfer 28 of the restricting projection 27 is supported from below by the chamfer 48 of the locking member 40. Since the 2 nd cover 20 is opened, the claw receiving portion 26 of the 2 nd cover 20 is located above the holding claw 45 of the locking member 40. Since the locking member 40 is located at the front position P1, the locking pawl 47 of the locking member 40 is disengaged rearward from the ratchet teeth 34 of the swing clamp 30.

As shown in fig. 8 (B), when the 2 nd cover 20 is closed with respect to the 1 st cover 10, the restricting projection 27 of the 2 nd cover 20 is pressed toward the bottom wall 12 of the 1 st cover 10. Since the locking member 40 is in oblique contact with the chamfer surfaces 48, 28 of the restricting projection 27, the locking member 40 is slid rearward by the pressing operation of the restricting projection 27. The linear protrusion 49 (see fig. 6) of the locking member 40 abuts against the opening edge (the rear edge of the opening 18) of the 1 st cover 10 to position the locking member 40 at the rear position P2. In a state where the 1 st cover 10 and the 2 nd cover 20 are closed, the holding claws 45 of the locking member 40 are engaged with the claw receiving portions 26 of the 2 nd cover 20.

As shown in fig. 8 (C), the front end of the in-line screwdriver 50 is engaged with the hook-shaped hooking portion 35 of the swing clamp 30, and the swing clamp 30 is pressed down by the in-line screwdriver 50. The swing clamp 30 approaches the 1 st cover 10, thereby clamping the cable 2 from above and below by the swing clamp 30 and the 1 st cover 10. The locking pawl 47 of the locking member 40 engages with the ratchet teeth 34 of the swing clamp 30 to restrict the release of the clamp. At this time, since the sliding of the locking member 40 is restricted by the restricting projection 27, the locking claw 47 does not come off the ratchet 34, and the cable 2 is prevented from coming off the electrical connector 1.

As shown in fig. 9 a, when the clamping by the electrical connector 1 is released, the holding claws 45 of the locking member 40 are released from the engagement with the claw receiving portions 26 of the 2 nd cover 20 by the in-line screwdriver 50 (see fig. 8C). Since the 2 nd cover 20 and the swing clamp 30 are coupled via the long hole 29, when the 2 nd cover 20 is opened with respect to the 1 st cover 10, only the 2 nd cover 20 moves in a state where the swing clamp 30 is engaged with the engagement member 40. At this time, the restricting projection 27 of the 2 nd cover 20 is disengaged from the bottom wall 12 of the 1 st cover 10 to release the slide restriction of the locking member 40 by the restricting projection 27.

As shown in fig. 9B, a straight screwdriver 50 is inserted from the opening 18 (see fig. 6) of the 1 st cover 10, and the locking member 40 is slid forward by the straight screwdriver 50. At this time, the locking member 40 is positioned at the front position P1, and the locking pawl 47 is disengaged from the ratchet 34 to release the clamping of the cable 2. As shown in fig. 9 (C), the front end of the in-line driver 50 is engaged with the hook 35 of the swing clamp 30, and the in-line driver 50 lifts the swing clamp 30. In this way, the cable 2 is removed from the electrical connector 1.

As described above, according to the present embodiment, even if the outer diameter dimension of the cable 2 changes, the swing clamp 30 approaches the 1 st cover 10, and the cable 2 is clamped by the swing clamp 30 and the 1 st cover 10. Further, since the hook portion 35 is formed in the swing clamp 30, the swing clamp 30 can be brought close to the 1 st cover 10 and the cable 2 can be wired to the electrical connector 1 using a more general tool without using pliers or the like. In particular, in the present embodiment, the in-line screwdriver 50 is prepared 1, and connection of the cable 2 to the electrical connector 1 and removal of the cable 2 from the electrical connector 1 can be performed.

In addition, in the electrical connector of the present embodiment, a plurality of ratchets are formed in the pawl arm of the swing clamp, but the number of ratchets of the pawl arm is not particularly limited. One ratchet may be formed in the pawl arm, or 3 or more ratchet may be formed in the pawl arm.

In the electrical connector of the present embodiment, the 1 st and 2 nd covers are held in the closed state by snap-coupling, but the 1 st and 2 nd covers may be held in the closed state by coupling methods other than snap-coupling.

In the electrical connector of the present embodiment, the restricting projection of the 2 nd cover contacts the tip of the locking member to restrict the sliding of the locking member, but the restricting projection may contact a portion other than the tip of the locking member to restrict the sliding of the locking member.

In the electrical connector of the present embodiment, the 1 st cover is provided with the opening for partially exposing the locking member, but the opening may not be provided in the 1 st cover as long as the locking member can be slidably operated.

In the electrical connector of the present embodiment, the locking member is inserted into the gap between the holding portion and the bottom wall of the 1 st cover, but the method of installing the locking member is not limited as long as the locking member is slidably installed with respect to the 1 st cover.

In the electrical connector of the present embodiment, the clamping operation and the clamping releasing operation are performed using an in-line screwdriver as a tool, but the clamping operation and the clamping releasing operation may be performed using a long tool such as a cross-shaped screwdriver.

In the electric connector of the present embodiment, the hooking portion is formed in a hook shape, but the hooking portion may be formed in any shape as long as the tool can be engaged with the swing clamp. For example, the hooking portion may be formed by a groove provided in the swing clamp.

In the electrical connector of the present embodiment, the positioning portion is formed in the swing clamp, but the positioning portion may not be necessarily formed in the swing clamp.

As described above, the electrical connector (1) of the present embodiment is an electrical connector for connecting a cable (2), and includes: a 1 st cover (10) that covers the outer peripheral surface of the cable from one side (lower side); a 2 nd cover (20) covering the outer peripheral surface of the cable from the other side (upper side); and a swing clamp (30) which is connected to the 2 nd cover and is opposite to the 1 st cover, wherein the swing clamp is close to the 1 st cover to clamp the cable by the swing clamp and the 1 st cover, a hook part (35) capable of clamping the front end of the tool (the in-line screwdriver 50) is formed on the swing clamp, and the swing operation of the swing clamp is received by the hook part. According to this structure, even if the outer diameter dimension of the cable varies, the swing clamp approaches the 1 st cover to clamp the cable by the swing clamp and the 1 st cover. Further, since the swing clamp is formed with the hooking portion, the cable can be wired to the electrical connector by bringing the swing clamp close to the 1 st cover without using pliers or the like and using a more general tool.

In the electric connector of the present embodiment, the hooking portion protrudes in a hook shape from the outer surface of the swing clamp. According to this configuration, the tip of the tool can be engaged with the hook-shaped engagement portion to operate the swing clamp.

In the electric connector of the present embodiment, a positioning portion (36) for positioning the tool in the width direction (left-right direction) is formed in the swing clamp. According to this structure, the deviation between the hooking portion of the swing clamp and the tool in the width direction is suppressed, and the tool is less likely to fall off from the hooking portion.

The electric connector of the embodiment is provided with a locking member (40) arranged on the 1 st cover for locking the swing clamp, a ratchet (34) is formed on the swing clamp, a locking claw (47) is formed on the locking member, the locking claw is engaged with the ratchet to limit the release of the clamping in the clamping state of the cable, and the locking member can slide in a direction of enabling the locking claw to be separated from the ratchet. According to this structure, the locking pawl engages with the ratchet in the clamped state of the cable to restrict the clamp release, thereby preventing the cable from coming off the electrical connector. Further, by sliding the locking member to disengage the locking pawl from the ratchet teeth to allow the cable to be released from the clamp, the swing clamp is separated from the 1 st cover, and the cable can be easily removed from the electrical connector.

In the electric connector of the embodiment, a holding claw (45) is formed on the locking component, a claw bearing part (26) is formed on the 2 nd cover, the 1 st cover and the 2 nd cover are connected in an openable and closable manner at the front end side (front side) of the insertion direction of the cable, and the holding claw and the claw bearing part are in buckling connection in a state that the 1 st cover and the 2 nd cover are closed. According to this structure, the 1 st cover and the 2 nd cover can be mechanically coupled. In addition, the 2 nd cover can be easily opened from the 1 st cover.

In the electric connector of the embodiment, the limiting protrusion (27) protrudes from the 2 nd cover towards the 1 st cover, the sliding of the locking member is limited by the limiting protrusion in a state that the 1 st cover and the 2 nd cover are closed, and the sliding limitation of the locking member by the limiting protrusion is released in a state that the 1 st cover and the 2 nd cover are opened. According to this structure, in the state where the 1 st cover and the 2 nd cover are closed, the sliding of the locking member is restricted by the restricting projection, and therefore the locking pawl does not come off the ratchet, thereby preventing the cable from coming off the electrical connector. By opening the 2 nd cover from the 1 st cover, the sliding restriction of the locking member is released, and therefore the locking pawl is disengaged from the ratchet, and the cable can be easily removed from the electrical connector.

In the electric connector of the present embodiment, a long hole (29) is formed in the 2 nd cover, a connecting shaft (31) is formed in the swing clamp, the swing clamp and the 2 nd cover are connected by inserting the connecting shaft into the long hole, the long hole extends in the opposite direction (up-down direction) of the 1 st cover and the 2 nd cover, and the relative positional relationship between the 2 nd cover and the swing clamp is changed by moving along the long hole by the connecting shaft. According to this structure, the 2 nd cover can be opened from the 1 st cover in a state where the cable is clamped by the swing clamp.

In the electric connector of the embodiment, an opening (18) for exposing the locking member is formed in the 1 st cover, and the sliding operation of the locking member is received through the opening.
