Description

Electric connector

Technical Field

The present invention relates to an electrical connector.

Background

There are cases where an operator on site connects a cable to an electrical connector, but the outer diameter size of the cable varies depending on the number of core wires and the like, so that the electrical connector has to be prepared depending on the outer diameter size of the cable. Therefore, a clip-type electrical connector capable of connecting wires irrespective of the outer diameter of a cable has been proposed (for example, refer to patent document 1). In the electrical connector described in patent document 1, the cable is clamped from above and below by the claw of the fixed cover and the claw of the movable cover. The ratchet mechanism restricts the opening of the movable cover relative to the fixed cover, and maintains a state in which the cable is sandwiched between the fixed cover and the movable cover.

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

However, when the cable is attached to the electrical connector described in patent document 1, the movable cover cannot be opened with respect to the fixed cover, so that it is difficult to remove the cable from the electrical connector.

Disclosure of Invention

The present invention has been made in view of the above, and an object thereof is to provide an electrical connector capable of easily connecting a cable and easily removing the cable even if the outer diameter dimension of the cable is changed.

An electrical connector according to an aspect of the present invention is an electrical connector for connecting cables, comprising: a first cover covering an outer peripheral surface of the cable from one side; a second cover covering the outer peripheral surface of the cable from the other side; a swing holder coupled to the second cover and opposed to the first cover; and a locking member provided on the first cover and locking the swing clamp, wherein ratchet teeth are formed on the swing clamp, and a locking claw is formed on the locking member, so that the swing clamp approaches the first cover and the cable is clamped between the swing clamp and the first cover, and in a state of clamping the cable, the locking claw is engaged with the ratchet teeth to restrict clamping release, and the locking member can slide in a direction in which the locking claw is separated from the ratchet teeth, thereby solving the problem.

In the electrical connector according to the aspect of the present invention, even if the outer diameter dimension of the cable is changed, the cable can be held by the swing holder and the first cover by bringing the swing holder close to the first cover. In a state where the cable is clamped, the locking claw engages with the ratchet teeth to restrict the clamping release, preventing the cable from being detached from the electrical connector. Further, by sliding the locking member to separate the locking claw from the ratchet teeth to release the cable from the clamping, the swing clamp is separated from the first cover, and the cable can be easily removed from the electrical connector.

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 accommodates an end portion of the cable 2 through the first cover 10 and the second cover 20. The first cover 10 covers the outer peripheral surface of the cable 2 from the lower side, and the second cover 20 covers the outer peripheral surface of the cable 2 from the upper side. A housing 5 is housed in front of the first and second covers 10 and 20, and an end of the cable 2 is connected to the housing 5. A plug 6 is provided on the front surface of the housing 5, and the plug 6 protrudes forward from the first cover 10 and the second cover 20.

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 clamp 30 is connected to the rear portion of the second cover 20 so as to be swingable in the up-down direction, and the swing clamp 30 faces the first cover 10 via the cable 2. The swing clamp 30 approaches the first cover 10 to clamp the cable 2 from the up-down direction by the swing clamp 30 and the first cover 10. A tool hook 35 is formed on the outer surface of the swing clamp 30, and the swing clamp 30 is subjected to a swing operation by the hook 35.

A locking member 40 is provided at the rear of the first cover 10, and the swing clamp 30 is locked by the locking member 40. A pair of ratchet arms 33 protrude from both lateral ends of the swing clamp 30 toward the locking member 40, and a pair of locking arms 46 protrude from both lateral ends of the locking member 40 toward the swing clamp 30. A plurality of ratchet teeth 34 are formed on the pair of ratchet arms 33, and a locking claw 47 is formed on the pair of locking arms 46. The ratchet teeth 34 protrude forward from the ratchet arm 33, and the locking claw 47 protrudes rearward from the locking arm 46. The ratchet teeth 34 and the locking claws 47 form a ratchet mechanism that swings the swing clamp 30 only downward.

The first cover 10 and the second cover 20 are connected to each other in an openable and closable manner via the housing 5 on the front side of the electrical connector 1. A pair of holding arms 44 protrude upward from both ends of the locking member 40 in the lateral direction, and a part of the rear ends of both side walls 21 of the second cover 20 protrude rearward. A holding claw 45 is formed on the pair of holding arms 44, and claw receiving portions 26 are formed on both side walls 21 of the second cover 20 through protruding portions. The holding claws 45 and the claw receiving portions 26 are engaged by snap-fitting, whereby the first cover 10 and the second cover 20 are mechanically coupled by the elastic force of the holding arms 44.

As shown in fig. 3, the first cover 10 is a die-cast molded 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 forward from the bottom wall 12, and a swing shaft 13 protrudes from the inner surfaces of the front portions 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), and the first cover 10 is attached to the housing 5 so as to be openable downward. A portion of the rear portion of the pair of side walls 11 is cut out to be concave, and the pair of cutouts 14 lowers the upper edges of the pair of side walls 11 by one step. 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 on the inner side in the left-right direction than the pair of cutouts 14. As will be described in detail later, the pair of connecting shafts 31 of the swing clamp 30 (see fig. 4) are supported from below by the tips of the pair of support columns 16. 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 along 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 is slidably held inside the holding portion 17 in the front-rear direction (see fig. 5). 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 second cover 20 is a die-cast molded 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 forward from the upper wall 22, and a swing shaft 24 protrudes 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 of the housing 5 (see fig. 2), and the second cover 20 is attached to the housing 5 so as to be openable upward. A part of the rear portions of the pair of side walls 21 protrudes downward, and the pair of protruding portions 25 lowers the lower edges of the pair of side walls 21 by one step. In a state where the first cover 10 and the second cover 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 enters the cutout 14, and a gap into which the holding claw 45 of the locking member 40 enters is formed by the claw receiving portion 26 of the second cover 20 and the high wall portion 15 of the first 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). As will be described later, the pair of restricting projections 27 abut against the distal ends of the locking members 40 to restrict forward sliding of the locking members 40 (see fig. 8B). The corners of the pair of restricting projections 27 on the side of the locking member 40 are chamfered to avoid interference between the pair of restricting projections 27 and the locking member 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, and the swing clamp 30 is swingably coupled to the second cover 20. The pair of elongated holes 29 extend in the vertical direction, and the relative positional relationship between the second cover 20 and the swing clamp 30 is changed by moving the pair of connecting shafts 31 along the pair of elongated holes 29. Thus, the swinging holder 30 can be opened without interlocking with the opening and closing operation of the second cover 20, while maintaining the state in which the cable 2 is held by the swinging holder 30 (see fig. 9 a).

The swing clamp 30 is a die-cast molded product, and is provided so as to face the first cover 10. A pair of connecting shafts 31 are formed at both ends of the tip end portion of the swing clamp 30 in the lateral direction, and the swing clamp 30 swings about the pair of connecting shafts 31 as fulcrums. A 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 are engaged with the outer peripheral surface of the cable 2, and the cable 2 is strongly clamped by the swing clamp 30 and the first cover 10. A pair of ratchet 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 ratchet arm 33.

A 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 (see fig. 1 in particular). The swing clamp 30 is opened and closed by hooking the tip of a tool such as a straight screwdriver to the hooking portion 35. A pair of positioning portions 36 protrude from the outer surface of the swing clamp 30 at a position on the rear side of the hooking portion 35. The pair of positioning portions 36 are provided so as to avoid the center portion in the left-right direction of the swing clamp 30, and the tool is inserted between the pair of positioning portions 36, so that the tool is positioned 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 not easily separated 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 in the front-rear direction, and the pair of base portions 41 are connected via the front-rear bridging portions 42, 43. The corners of the front 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. A holding arm 44 protrudes upward from the front portions of the pair of base portions 41, and a holding claw 45 is formed at the front ends of the pair of holding arms 44. A locking arm 46 protrudes obliquely rearward and upward from the central portion of the pair of base portions 41, and a locking claw 47 is formed at the front end of the pair of locking arms 46.

As shown in fig. 5 and 6, the front and rear bridging portions 42 and 43 are inserted into the gap between the bottom wall 12 of the first cover 10 and the holding portion 17 from behind. As will be described in detail later, the locking member 40 is slidable in a direction to separate the locking pawl 47 from the ratchet teeth 34. The front bridge portion 42 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 that enters the opening 18 is formed in the rear bridge portion 43. The linear convex portion 49 is in contact with the opening edge, and the locking member 40 is positioned at a rear position P2 where the locking claw 47 and the ratchet teeth 34 can be engaged (see fig. 8 (B)).

The cable holding 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) cut along line A-A. Fig. 7 (C) is a cross-sectional view of the electrical connector of fig. 7 (a) cut 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. The ratchet teeth 34 are engaged with the engagement claws 47 to prevent the swing holder 30 from swinging upward, thereby restricting the release of the holding. Maintaining the clamped state of the cable 2 and preventing the cable 2 from being detached from the electrical connector 1. At this time, the locking member 40 is restricted from sliding forward by the restricting projection 27 of the second cover 20, and the locking claw 47 does not come off from the ratchet teeth 34.

Further, the swing clamp 30 is formed with upper and lower ratchet teeth 34, and the clamping position of the swing clamp 30 is adjusted to two stages by engagement of the locking claw 47 with any one of the ratchet teeth 34. When the cable 2 of a relatively thin type as shown in fig. 7 a is held, the ratchet teeth 34 on the upper side are engaged with the engagement claws 47, and when the cable (not shown) of a relatively thick type is held, the ratchet teeth 34 on the lower side are engaged with the engagement claws 47. In this way, by forming a plurality of ratchet teeth 34 on the swing clamp 30, it is possible to clamp a cable of a type in which the outer diameter size difference is large.

As shown in fig. 7 (a) and (B), a coupling shaft 31 of the swing clamp 30 is inserted into the long hole 29 of the second cover 20. At this time, the coupling shaft 31 is supported from the lower side by the support column 16 of the first cover 10 inside the second cover 20, and the coupling shaft 31 is sandwiched from the upper side and the lower side 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 first cover 10 and the second cover 20 are closed, the holding claws 45 of the locking member 40 enter the gap between the claw receiving portions 26 of the second cover 20 and the high wall portion 15 of the first cover 10 from the inside. Thereby, the holding claws 45 are snap-engaged with the claw receiving portions 26 of the second cover 20.

The clamping operation and the clamping release operation of the electrical connector will be described with reference to fig. 8 and 9. Fig. 8 is a transition diagram of the clamping operation of the electrical connector of the present embodiment. Fig. 9 is a transition diagram of the clamping releasing operation of the electric connector according to the present embodiment.

As shown in fig. 8 (a), the second cover 20 is opened with respect to the first cover 10 before the clamping action of the electrical connector 1. At this time, the restricting projection 27 of the second cover 20 is separated from the bottom wall 12 of the first 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 second cover 20 is opened, the claw receiving portion 26 of the second 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 claw 47 of the locking member 40 is separated rearward from the ratchet teeth 34 of the swing clamp 30.

As shown in fig. 8 (B), when the second cover 20 is closed with respect to the first cover 10, the restricting projection 27 of the second cover 20 is pressed toward the bottom wall 12 of the first cover 10. Since the locking member 40 and the chamfer surfaces 48, 28 of the restricting projection 27 are in contact with each other obliquely, the locking member 40 slides rearward due to the pushing-in operation of the restricting projection 27. The linear convex portion 49 (see fig. 6) of the locking member 40 abuts against the opening edge (the rear edge of the opening 18) of the first cover 10, and the locking member 40 is positioned at the rear position P2. Then, in a state where the first cover 10 and the second cover 20 are closed, the holding claws 45 of the locking member 40 are snap-engaged with the claw receiving portions 26 of the second cover 20.

As shown in fig. 8 (C), the front end of the in-line screwdriver 50 is hooked to the hook-shaped hooking portion 35 of the swing clamp 30, and the in-line screwdriver 50 presses down the swing clamp 30. The swing clamp 30 approaches the first cover 10, and clamps the cable 2 from above and below by the swing clamp 30 and the first cover 10. The locking claw 47 of the locking member 40 engages with the ratchet teeth 34 of the swing clamp 30 to restrict the clamp release. At this time, the locking claw 47 is not separated from the ratchet teeth 34 by restricting the sliding of the locking member 40 by the restricting projection 27, and the cable 2 can be prevented from being separated from the electrical connector 1.

As shown in fig. 9 (a), when the clamping of 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 second cover 20 by the in-line screwdriver 50 (see fig. 8 (C)). Since the second cover 20 and the swing clamp 30 are coupled via the long hole 29, when the second cover 20 is opened with respect to the first cover 10, only the second cover 20 moves in a state where the swing clamp 30 is locked to the locking member 40. At this time, the restricting projection 27 of the second cover 20 is separated from the bottom wall 12 of the first cover 10, and the slide restriction of the locking member 40 by the restricting projection 27 is released.

As shown in fig. 9B, the in-line screwdriver 50 is inserted from the opening 18 (see fig. 6) of the first cover 10, and the locking member 40 is slid forward by the in-line screwdriver 50. At this time, the locking member 40 is positioned at the front position P1, and the locking claw 47 is separated from the ratchet teeth 34 to release the grip on the cable 2. Then, as shown in fig. 9 (C), the front end of the in-line screwdriver 50 is hooked to the hooking portion 35 of the swing clamp 30, and the in-line screwdriver 50 lifts the swing clamp 30. In this way, the cable 2 can be 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 cable 2 can be held by the swing holder 30 and the first cover 10 by bringing the swing holder 30 close to the first cover 10. In a state where the cable 2 is held, the locking claw 47 engages with the ratchet teeth 34 to restrict the release of the holding, preventing the cable 2 from being detached from the electrical connector 1. Further, by sliding the locking member 40 and releasing the locking claw 47 from the ratchet teeth 34 to release the clamping of the cable 2, the swing clamp 30 is released from the first cover 10, and the cable 2 can be easily removed from the electrical connector 1.

In the electrical connector of the present embodiment, a plurality of ratchet teeth are formed on the ratchet arm of the swing clamp, but the number of ratchet teeth of the ratchet arm is not particularly limited. One ratchet tooth may be formed in the ratchet arm, or three or more ratchet teeth may be formed in the ratchet arm.

In the electrical connector of the present embodiment, the first cover and the second cover are held in the closed state by the snap-fit coupling, but the first cover and the second cover may be held in the closed state by a coupling method other than the snap-fit coupling.

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

In the electrical connector of the present embodiment, the opening is formed in the first cover so as to partially expose the locking member, but the opening may not be formed in the first cover as long as the locking member can be slidably operated.

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

In the electrical connector of the present embodiment, the clamping operation and the clamping release operation are performed using a straight screwdriver as a tool, but the clamping operation and the clamping release operation may be performed using a straight tool such as a cross 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 hooked to the swing holder. 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 holder, but the positioning portion is not necessarily formed in the swing holder.

As described above, the electrical connector (1) of the present embodiment is an electrical connector for connecting a cable (2), and includes: a first cover (10) that covers the outer peripheral surface of the cable from one side (lower side); a second cover (20) that covers the outer peripheral surface of the cable from the other side (upper side); a swing clamp (30) connected to the second cover and opposed to the first cover; and a locking member (40) provided in the first cover and locking the swing holder, wherein ratchet teeth (34) are formed in the swing holder, and a locking claw (47) is formed in the locking member, so that the swing holder approaches the first cover and the cable is clamped between the swing holder and the first cover, and in a state of clamping the cable, the locking claw engages with the ratchet teeth to restrict the release of the clamping, and the locking member is capable of sliding in a direction in which the locking claw is separated from the ratchet teeth. According to this structure, even if the outer diameter dimension of the cable varies, the cable can be gripped by the swing gripper and the first cover by bringing the swing gripper close to the first cover. In a state where the cable is clamped, the locking claw engages with the ratchet teeth to restrict the clamping release, preventing the cable from being detached from the electrical connector. Further, by sliding the locking member, the locking claw is separated from the ratchet teeth, thereby releasing the clamping of the cable, and the swing clamp is separated from the first cover, thereby making it possible to easily remove the cable from the electrical connector.

In the electric connector of the embodiment, a holding claw (45) is formed on the locking component, a claw receiving part (26) is formed on the second cover, the first cover and the second 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 is in buckling connection with the claw receiving part in a state that the first cover and the second cover are closed. According to this structure, the first cover and the second cover can be mechanically coupled. In addition, the second cover can be easily opened from the first cover.

In the electric connector of the embodiment, a limiting protrusion (27) protrudes from the second cover towards the first cover, the sliding of the locking component is limited by the limiting protrusion when the first cover and the second cover are closed, and the sliding limitation of the limiting protrusion on the locking component is released when the first cover and the second cover are opened. According to this structure, in the state where the first cover and the second cover are closed, the sliding of the locking member is restricted by the restricting projection, so that the locking claw does not come off from the ratchet teeth, and the cable can be prevented from coming off from the electrical connector. By opening the second cover from the first cover, the sliding restriction of the locking member is released, so that the locking claw is separated from the ratchet teeth, and the cable can be easily removed from the electrical connector.

In the electrical connector of the present embodiment, the corners of the locking member side of the restricting projection are chamfered. According to this structure, interference between the restricting projection and the locking member can be avoided.

In the electric connector of the present embodiment, a long hole (29) is formed in the second cover, a connecting shaft (31) is formed in the swing holder, the connecting shaft is inserted into the long hole, the swing holder is connected with the second cover, the long hole extends in the opposite direction (up-down direction) of the first cover and the second cover, the connecting shaft moves along the long hole, and the relative position relationship between the second cover and the swing holder changes. According to this structure, the second cover can be kept open from the first cover while holding the cable by the swing clamp.

In the electric connector of the embodiment, an opening (18) for exposing the locking member partially is formed in the first cover, and the sliding operation of the locking member is received through the opening. According to this structure, the locking member is slid through the opening, and the cable can be easily removed from the electrical connector.

In the electric connector of the embodiment, a linear convex part (49) which enters into the opening is formed on the locking part, and the locking part is positioned at a position where the locking claw and the ratchet teeth can be meshed by the contact of the linear convex part with the edge of the opening. According to this structure, the locking member can be positioned in a position where the locking claw and the ratchet teeth can be engaged with each other by a simple structure.

In the electric connector of the present embodiment, a sharp convex portion (32) protrudes from the front end (rear end) of the swing clamp toward the first cover side. According to this structure, the sharp convex portion of the swing clamp is engaged with the outer peripheral surface of the cable, so that the cable can be strongly clamped by the swing clamp and the first cover.

In the electric connector of the embodiment, a pair of ratchet arms (33) protrude from both widthwise ends (both left and right ends) of the swing clamp to the locking member side (lower side), a pair of locking arms (46) protrude from both widthwise ends (both left and right ends) of the locking member to the swing clamp side (upper side), ratchet teeth are formed on the pair of ratchet arms, and locking claws are formed on the pair of locking arms.
