Description

Technical Field

[0001] This disclosure relates to rod-type connectors. Background Technology

[0002] Conventionally, rod-type connectors are known that engage with a counterpart connector via an operating lever. For example, the rod-type connectors described in Patent Documents 1-3 below have a lever in the wire cover that covers the wire lead-out surface of the housing. The housing of these rod-type connectors has a sliding member that slides via the operation of the lever. A cam groove is formed in the sliding member, which receives a cam follower provided in the counterpart connector. When engaging with the counterpart connector, the sliding member is held in a predetermined position relative to the housing. This predetermined position refers to the position where the cam follower of the counterpart connector engages with the cam groove. The sliding member engages the cam follower with the cam groove and slides from the predetermined position via the operating lever. The rod-type connector achieves proper engagement with the counterpart connector through the engagement of the cam groove of the sliding member and the cam follower of the counterpart connector.

[0003] In such rod-type connectors, the rod-type connectors described in Prior Art Documents 1 and 2 have rack teeth on the sliding member and gears on the rod. The sliding member of this rod-type connector moves through the meshing of the gears and rack teeth.

[0008] Patent Document 3: Japanese Patent Application Publication No. 2014-165031 Summary of the Invention

[0009] The problem that the invention aims to solve

[0010] However, when assembling the wire cover into the housing, sometimes the gear of the wire cover contacts the rack teeth of the slider, causing the slider to move from its intended position. When the slider deviates from its intended position, the cam follower and cam groove of the opposite connector cannot engage. Therefore, it is desirable to prevent the gear of the wire cover from contacting the rack teeth of the slider and causing the slider to move.

[0011] Therefore, this disclosure aims to provide a rod connector that, when the wire cover is assembled into the housing, prevents the gear of the wire cover from contacting the rack teeth of the sliding member and causing the sliding member to move.

[0012] Solution for solving the problem

[0013] The rod-type connector disclosed herein comprises: a housing; a sliding member configured to move relative to the housing in a first direction and having a plurality of rack teeth arranged in the first direction; a wire cover disposed on the housing and covering the wire lead-out surface of the housing; and a rod rotatably disposed on the wire cover and having a gear that meshes with the rack teeth to move the sliding member. The housing has: a fulcrum portion supporting the wire cover for rotation; and a positioning portion contacting the wire cover such that the gear faces a position capable of meshing with the rack teeth.

[0014] Invention Effects

[0015] According to this disclosure, a rod-type connector can be provided such that, when the wire cover is assembled into the housing, it can prevent the gear of the wire cover from contacting the rack teeth of the sliding member, thereby preventing the sliding member from shifting.

[0022] [Description of embodiments of this disclosure]

[0023] First, the implementation methods of this disclosure are listed and explained.

[0024] The rod connector disclosed herein,

[0025] (1) The device comprises: a housing; a sliding member configured to move relative to the housing in a first direction and having a plurality of rack teeth arranged in the first direction; a wire cover disposed on the housing and covering the wire lead-out surface of the housing; and a rod rotatably disposed on the wire cover and having a gear meshing with the rack teeth to move the sliding member. The housing has: a fulcrum portion supporting the wire cover for rotation; and a positioning portion contacting the wire cover such that the gear faces a position capable of meshing with the rack teeth. With this structure, when the wire cover is rotated in a state supported by the fulcrum portion, the wire cover can be positioned by the meshing of the gear and rack teeth. Therefore, when the wire cover is assembled onto the housing, it is possible to prevent the gear of the wire cover from contacting the rack teeth of the sliding member and causing the sliding member to shift.

[0026] (2) Preferably, the fulcrum portion has a protrusion extending from the housing in a direction intersecting the first direction, the wire cover has a fitting portion that engages with the protrusion in a direction parallel to the first direction, and the positioning portion is positioned relative to the fitting portion on the side opposite to the protrusion, having a surface curved along the rotation direction of the wire cover. This is because, according to this structure, the wire cover can be easily positioned.

[0027] (3) Preferably, a gear mounting portion is provided in the middle of the housing in the first direction. When the wire cover is assembled into the housing, the gear is mounted in the gear mounting portion, and both the protrusion and the positioning portion are provided on one side relative to the gear mounting portion in the first direction. This is because, according to this structure, the housing can be miniaturized compared to the case where the protrusion is provided on one side of the housing in the first direction and the positioning portion is provided on the other side.

[0028] (4) Preferably, the fulcrum portion has a rotation axis that serves as the rotation center of the wire cover, and the corner of the contact surface of the rotation axis that contacts the wire cover is curved. This is because, according to this structure, the rotation of the wire cover can be performed more smoothly compared to the case where the corner of the contact surface of the rotation axis that contacts the wire cover is right-angled.

[0029] [Details of the embodiments of this disclosure]

[0030] The following is a reference to the appendix. Figure 1 Specific examples of the rod-type connector C disclosed herein will be described below. Furthermore, the invention is not limited to these examples, but as indicated by the claims, it is intended to include all modifications within the meaning and scope equivalent to the claims.

[0031] like Figure 1As shown, the rod connector C includes a housing 10, a wire cover 30, a rod 40, a fulcrum 50, and a positioning part 60. Hereinafter, the component with the wire cover 30 assembled will be described...

Additionally, it will be related to... Figure 1 The outer side of the orthogonal direction of the paper is defined as the left side, and the inner side as the right side.

[0032] The housing 10 is made of synthetic resin. The housing 10 is elongated in the front-to-back direction. For example... Figure 2 As shown, the housing 10 is provided with multiple terminal storage chambers 11 for storing terminal parts. The multiple terminal storage chambers 11 are arranged in the front-back direction and the left-right direction.

[0033] The terminal components are stored in the terminal storage chamber 11 from the top. The terminal components are connected to the end of the wire W. The wire W extends upward from the wire lead-out surface 12 of the housing 10. The bundle of wire W is bent backward inside the wire cover 30.

[0034] like Figure 2 and Figure 3 As shown, the housing 10 is provided with a locking part 13 for locking the wire cover 30 into an assembled state. The locking part 13 is provided at the front end of the housing 10. A pair of locking parts 13 are provided on the left and right sides of the housing 10.

[0035] A locking part 13 is provided on a locking wall 14 that protrudes upward from the wire lead-out surface 12 of the housing 10. The locking part 13 protrudes outward from the locking wall 14 (the right locking part 13 protrudes to the right from the right locking wall 14, and the left locking part 13 protrudes to the left from the left locking wall 14). The locking part 13 engages with a locking receiving part 31 provided on the wire cover 30.

[0036] A gear configuration section 15 is provided in the housing 10 (see reference). Figure 6 The gear mounting section 15 is configured with the gear 44 of the rod 40 when the wire cover 30 is assembled into the housing 10. The gear mounting section 15 is located at the center of the housing 10 in the front-rear direction (first direction). Figure 2 and Figure 3 As shown, a pair of gear configuration portions 15 are provided on the left and right sides of the housing 10. The gear configuration portion 15 is a recessed portion with an open upper side and a recessed lower side. The gear 44 of the rod 40 engages with the gear configuration portion 15 from the upper side.

[0037] like Figure 2 and Figure 3As shown, a support receiving portion 16 is provided in the housing 10. The support receiving portion 16 supports the support portion 35 of the wire cover 30 when the wire cover 30 is assembled into the housing 10. The support receiving portion 16 is located rearward of the gear configuration portion 15. A pair of support receiving portions 16 are provided on the left and right sides of the housing 10. The support receiving portion 16 is a recessed portion with an open top.

[0038] The bottom surface 16A of the support receiving part 16 is parallel to the wire lead-out surface 12. The side surface 16B of the support receiving part 16 is perpendicular to the wire lead-out surface 12. The support receiving part 16 has a fulcrum part 50 and a positioning part 60. The fulcrum part 50 and the positioning part 60 will be described in detail later.

[0039] The housing 10 includes a sliding member 20 (see reference). Figure 5 The sliding member 20 is made of synthetic resin. The sliding member 20 is flat. A pair of sliding members 20 are provided on the left and right sides of the housing 10. A cam groove 21 is formed in the sliding member 20 for engagement with the cam follower of the opposite connector. The sliding member 20 is movable in the front-rear direction (first direction). The sliding member 20 moves between an initial sliding position and a completed sliding position; the sliding member 20 remains in the initial sliding position when engaging with the opposite connector, and remains in the completed sliding position when engaging with the opposite connector. Figure 5 The slider 20, positioned in its initial position, is indicated by a double-dotted line. The completed engagement position of the slider is further rearward than its initial position (in...). Figure 5 The position is on the right side (in the middle). The slider 20 has a plurality of rack teeth 22 arranged in the front-back direction. The rack teeth 22 are disposed on the upper surface of the slider 20.

[0040] The wire cover 30 is made of synthetic resin. For example... Figure 1 As shown, the wire cover 30 is assembled onto the housing 10, covering the wire lead-out surface 12 of the housing 10. Figure 4 As shown, the wire cover 30 has a pair of left and right side portions 30A and an upper portion 30B connecting the upper ends of the pair of side portions 30A. The upper portion 30B faces the wire lead-out surface 12 when the wire cover 30 is assembled into the housing 10. The lower surface of the side portions 30A is parallel to and close to the wire lead-out surface 12 of the housing 10 when the wire cover 30 is assembled into the housing 10. Support shafts 33 for mounting rods 40 are provided on the left and right side portions 30A. The wire cover 30 has openings at its lower and rear sides. The wire W is bent rearward by the wire cover 30. The rear end of the wire cover 30 has a wire outlet 34 through which the wire W is led out rearward.

[0041] A locking receiving part 31 is provided at the front end of the wire cover 30, into which the locking part 13 fits. The locking receiving part 31 is provided on the left and right sides of the wire cover 30. The locking receiving part 31 is a hole that passes through in the left and right direction.

[0042] like Figure 4 As shown, the wire cover 30 has a support portion 35. The support portion 35 is fitted into a support receiving portion 16 provided in the housing 10. A pair of support portions 35 are provided on the left and right sides of the wire cover 30. The support portion 35 is located at the rear end below the side portion 30A of the wire cover 30. The support portion 35 is located at the center in the front-rear direction between the front end of the wire cover 30 and the wire outlet 34. The left-right dimension of the support portion 35 is smaller than the left-right dimension of the side portion 30A.

[0043] like Figure 6 As shown, the lower surface of the support portion 35 has an inclined surface 36, a horizontal surface 37, and a curved surface 38. The inclined surface 36 is located at the rear end of the support portion 35. The inclined surface 36 is inclined in a rearward upward manner when the wire cover 30 is assembled into the housing 10. The inclined surface 36 forms the lower surface of the fitting portion 52 described later. The horizontal surface 37 is located at the center of the support portion 35 in the front-rear direction. The horizontal surface 37 contacts the bottom surface 16A of the support receiving portion 16 when the wire cover 30 is assembled into the housing 10. The curved surface 38 is located at the front end of the support portion 35. The curved surface 38 is curved in a forward upward manner when the wire cover 30 is assembled into the housing 10. The support portion 35 has an outer wall portion 39 disposed on the outer side of the curved surface 38 (right side in the right-side support portion 35, left side in the left-side support portion 35). The outer wall portion 39 runs along the side surface 16B of the support receiving portion 16. The support portion 35 has a fitting portion 52. The fitting portion 52 will be described in detail later.

[0044] like Figure 4 As shown, the rod 40 has a pair of left and right side plates 41 and a connecting portion 42 that connects one end of the side plates 41 to each other. Mounting holes 43 are provided in the left and right side plates 41 for fitting support shafts 33. By inserting the support shafts 33 into the mounting holes 43, the rod 40 is mounted to the wire cover 30 in a rotatable state.

[0045] The lever 40 can rotate between the initial position and the completed engagement position. The lever 40 remains in the initial position when it begins to engage with the connector on the other side, and remains in the completed engagement position when it completes to engage with the connector on the other side. Figure 4 The image shows the rod 40 in its initial position. The rod engagement completion position is [position missing] compared to the initial position. Figure 4 The position is rotated counterclockwise. A gear 44 is provided on the outside of the side plate 41 of the rod 40, which meshes with the rack teeth 22. The rod 40 moves the sliding member 20 through the meshing of the gear 44 and the rack teeth 22.

[0046] The fulcrum 50 supports the wire cover 30 so that it can rotate. The fulcrum 50 is provided on the left and right sides of the housing 10. The fulcrum 50 is provided at the rear end of the housing 10. The fulcrum 50 has a protrusion 51 and a rotation shaft 53. The protrusion 51 protrudes upward from the housing 10 (in a direction intersecting the first direction).

[0047] like Figure 5 and Figure 6 As shown, a protrusion 51 is provided in the support receiving portion 16 of the housing 10. The protrusion 51 is a wall provided at the rear end of the support receiving portion 16. The protrusion 51 protrudes upward from the bottom surface 16A of the support receiving portion 16 along the rear end of the housing 10.

[0048] A rotating shaft 53 is located at the upper end of the protrusion 51. The rotating shaft 53 serves as the rotation center of the wire cover 30. The rotating shaft 53 protrudes forward from the upper end of the protrusion 51.

[0049] like Figure 5 and Figure 6 As shown, the corner of the contact surface of the rotating shaft 53 that contacts the wire cover 30 is a curved surface 56. The curved surface 56 is located at the upper and lower corners of the front end of the rotating shaft 53.

[0050] like Figure 5 and Figure 6 As shown, a first fitting recess 54 is provided on the lower side of the rotating shaft 53, where the fitting portion 52 engages. The front side of the first fitting recess 54 is open. The depth dimension (dimension in the front-to-back direction) of the first fitting recess 54 is greater than the protrusion dimension (dimension in the front-to-back direction) of the fitting portion 52. Accordingly, when the fitting portion 52 and the first fitting recess 54 are engaged, the rear ends of the fitting portion 52 and the rear ends of the first fitting recess 54 remain separated in the front-to-back direction. In other words, a gap is formed between the rear ends of the fitting portion 52 and the rear ends of the first fitting recess 54.

[0051] like Figure 5 and Figure 6 As shown, the fitting portion 52 is provided on the support portion 35 of the wire cover 30. The fitting portion 52 is provided at the rear end of the lower end of the support portion 35. The fitting portion 52 protrudes rearward along the lower surface of the support portion 35. The fitting portion 52 engages with the protrusion 51 from the front (in a direction parallel to the first direction). The fitting portion 52 engages with the first fitting recess 54.

[0052] like Figure 5 and Figure 6 As shown, a second fitting recess 55 is provided on the upper side of the fitting portion 52, where the rotating shaft 53 fits. The rear side of the second fitting recess 55 is open. Figure 6 As shown, the upper surface of the second fitting recess 55 extends obliquely upward in a rearward direction. The upper surface of the second fitting recess 55 is connected to the vicinity of the wire outlet 34 of the wire cover 30.

[0053] like Figure 5 and Figure 6 As shown, the positioning part 60 is provided on the support receiving part 16. The positioning part 60 is positioned where the fitting part 52 is interposed between the positioning part 60 and the protrusion 51. The positioning part 60 has a clearance S (see reference) that allows for fine adjustment of the position of the wire cover 30 in the front-rear direction so that the rack teeth 22 and the gear 44 mesh. Figure 6 Position the wire cover 30.

[0054] like Figure 3 As shown, the positioning part 60 is provided in the center of the support receiving part 16 in the left-right direction. The positioning part 60 protrudes upward from the bottom surface 16A of the support receiving part 16.

[0055] like Figure 5 and Figure 6 As shown, the positioning part 60 has a positioning surface 60A that is curved along the rotation direction of the wire cover 30. The positioning surface 60A is curved upwards as it moves forward from the rotation axis 53. When the wire cover 30 is assembled into the housing 10, the positioning surface 60A is parallel to the curved surface 38 of the support part 35. The vertical position of the upper end of the positioning surface 60A is approximately the same as the vertical position of the rotation axis 53.

[0056] Next, an example of the assembly operation of rod connector C will be described.

[0057] First, the terminal component is housed in the housing 10. Specifically, the terminal component fixed to the end of the wire W is inserted from the wire lead-out side 12 of the housing 10 into the terminal housing 11. When the terminal component is housed in the terminal housing 11, the wire W is led out from the wire lead-out side 12.

[0058] Next, the wire cover 30 is assembled into the housing 10 (see reference). Figure 5 and Figure 6 At this time, rod 40 is pre-positioned relative to wire cover 30 in its initial position. Slider 20 is pre-positioned relative to housing 10 in its initial sliding position. And, as... Figure 5 As shown, the wire cover 30 is tilted relative to the housing 10, and the support portion 35 of the wire cover 30 is inserted into the support receiving portion 16 of the housing 10 from the upper front. The fitting portion 52 of the wire cover 30 engages shallowly with the first fitting recess 54 of the housing 10 from the front. The fitting portion 52 is shaped into a tapered shape by the inclined surface 36, so it is easy to engage with the first fitting recess 54. On the other hand, the rotation axis 53 of the housing 10 engages shallowly with the second fitting recess 55. Accordingly, the wire cover 30 is supported on the housing 10 in a state that allows it to rotate around the rotation axis 53. The lower surface of the support portion 35 moves upward from the bottom surface 16A of the support receiving portion 16.

[0059] Next, the wire cover 30 is rotated forward. The wire cover 30 rotates about the rotation axis 53. While rotating the wire cover 30, its position in the front-to-back direction is finely adjusted. The support portion 35 of the wire cover 30 is displaced along the positioning surface 60A of the housing 10. The position of the support portion 35 of the wire cover 30 in the front-to-back direction is finely adjusted within the gap S between it and the positioning surface 60A.

[0060] The fitting part 52 is shifted rearward along the curved surface 56 of the rotation axis 53, as follows: Figure 6 As shown, it is deeply fitted into the first fitting recess 54. The upper surface of the fitting portion 52 is in surface contact with the lower surface of the rotating shaft 53. The horizontal surface 37 of the support portion 35 is in surface contact with the bottom surface 16A of the support receiving portion 16, and the curved surface 38 of the support portion 35 is disposed above the positioning surface 60A of the support receiving portion 16. By the contact between the support portion 35 and the positioning surface 60A, the gear 44 of the wire cover 30 is positioned to mesh with the rack teeth 22. Therefore, the gear 44 is in a state of meshing with the rack teeth 22 without contacting the rack teeth 22 and pressing the sliding member 20. Thus, when the wire cover 30 reaches the proper assembly position, the locking portion 13 of the housing 10 is engaged with the locking receiving portion 31 of the wire cover 30. Through the above, the assembly operation of the rod connector C is completed. Furthermore, the inclined surface 36 of the support portion 35 leaves the bottom surface 16A of the support receiving portion 16 both during the assembly of the wire cover 30 and after the assembly is completed.

[0061] Next, the function and effect of the rod connector C constructed as described above will be explained.

[0062] The rod connector C includes a housing 10, a slider 20, a wire cover 30, a rod 40, a fulcrum 50, and a positioning part 60. The slider 20 is configured to move relative to the housing 10 in a front-rear direction (first direction). The slider 20 has a plurality of rack teeth 22 arranged in the front-rear direction. The wire cover 30 is disposed on the housing 10 and covers the wire lead-out surface 12 of the housing 10. The rod 40 is rotatably disposed on the wire cover 30. The rod 40 has a gear 44 that meshes with the rack teeth 22, causing the slider 20 to move. The fulcrum 50 is disposed on the housing 10. The fulcrum 50 supports the wire cover 30 so that it can rotate. The positioning part 60 is disposed on the housing 10. The positioning part 60 contacts the wire cover 30 so that the gear 44 faces a position where it can mesh with the rack teeth 22.

[0063] With this structure, when the wire cover 30 is rotated while supported on the fulcrum 50, it can be positioned by the engagement of the gear 44 and the rack teeth 22. Therefore, when the wire cover 30 is assembled into the housing 10, it can prevent the gear 44 of the wire cover 30 from contacting the rack teeth 22 of the slider 20 and causing the slider 20 to move.

[0064] The fulcrum portion 50 has a protrusion 51 that projects upward from the housing 10. The wire cover 30 has a fitting portion 52 that engages with the protrusion 51 from the rear. The positioning portion 60 is located on the side opposite to the protrusion 51, separated by the fitting portion 52. The positioning portion 60 has a positioning surface 60A that is curved along the rotation direction of the wire cover 30. With this structure, the wire cover 30 can be easily positioned.

[0065] A gear mounting section 15 is provided at the center of the housing 10 in the front-rear direction. With the wire cover 30 assembled to the housing 10, the gear 44 is mounted on the gear mounting section 15. The protrusion 51 and the positioning section 60 are both positioned rearward of the gear mounting section 15 in the front-rear direction. With this structure, compared to the case where the protrusion and positioning section are provided on the front and rear sides of the housing 10 in the front-rear direction, the housing 10 can be miniaturized.

[0066] The fulcrum 50 has a rotation axis 53 that serves as the rotation center of the wire cover 30. The corner of the contact surface between the rotation axis 53 and the wire cover 30 is a curved surface 56. With this structure, the rotation of the wire cover 30 can be performed more smoothly compared to the case where the corner of the contact surface between the rotation axis and the wire cover is a right angle.
