Description

Technical Field

[0001] This specification discloses a switch.

Background Art

[0002] For the transmission of a vehicle, a push-type switch (push switch) is used for detecting modes such as neutral and reverse. The push switch is attached to the transmission case by screwing it into a screw hole that penetrates from the outside to the inside of the transmission case.

[0003] The push switch includes a pair of terminals located inside the switch body, a switching mechanism that controls conduction and interruption between these terminals, and a harness drawn out from these terminals to the outside of the body. The harness is connected to an external circuit such as the control circuit of the vehicle. For example, when the vehicle is put into the reverse mode by the driver's operation, the switching mechanism conducts between the pair of terminals. As a result, the external circuit connected to the harness lights up, for example, the reverse lamp of the vehicle. Consideration regarding the switch for the stop lamp of a vehicle is disclosed in Japanese Utility Model Laid-Open No. 59-77726.

Summary of the Invention

Problems to be Solved by the Invention

[0005] The harness for a push switch is usually routed from the side of the main unit for ease of connection to the built-in terminals. If the external connection point of the harness is located above the push switch, the harness routed from the side is bent upwards to connect to this external point. When the push switch is screwed into the screw hole, the tip of the harness, which becomes the external terminal, rotates in accordance with the rotation of the main unit. Because the harness is routed from the side of the main unit, the radius of rotation of the harness tip is usually larger than the radius of the main unit. Therefore, the position of the harness tip when rotation stops varies greatly depending on the stopping point of rotation. The position of the harness tip will vary greatly depending on the threading and the amount of force applied when screwing it in. This can lead to improper installation, such as the external terminal of the harness not reaching the connection point, or slack in the harness after installation. Slack in the harness increases the risk of disconnection due to vibration.

[0006] The inventor's intention is to provide a switch that allows for easy connection of a harness to its built-in terminals and reduces harness installation defects and sagging. [Means for solving the problem]

[0007] A switch according to one embodiment comprises a main body having a terminal block with a recess, a body located below the terminal block, and a terminal stay extending upward from the terminal block; a pair of terminals extending from the inside of the recess into the body; and a pair of harnesses connected to the pair of terminals. Each harness comprises a lead-out portion extending from the inside of the recess to the outside of the side surface of the terminal block, a main portion extending upward along the terminal stay with its tip becoming an external terminal, and an intermediate portion connecting the lead-out portion and the main portion. In a plan view, the main portion is located inside the outer edge of the terminal block. [Effects of the Invention]

[0008] In this switch, the harness has a lead-out portion that extends from inside a recess to the outside of the side surface of the terminal block. This makes it easy to connect the harness to the terminals. In this switch, the harness has a main portion that extends upward along the terminal stay and whose tip becomes an external terminal. In a plan view, the main portion is located inside the outer edge of the terminal block. Therefore, when the main body rotates, the rotation radius of the harness tip is smaller than the radius of the main body. The variation in the position of the harness tip depending on the stopping position of the rotation is small. This switch suppresses improper installation and slack of the harness.

[Figure 9] Figure 9 is a perspective view showing a switch according to another embodiment. [Modes for carrying out the invention]

[0010] Preferred embodiments will be described in detail below, with reference to drawings as appropriate.

[0011] Figure 1 is a perspective view showing a switch 2 according to one embodiment. This switch 2 is a push switch that can be used in a vehicle's transmission. In Figure 1, arrow X represents the front of the switch 2. The opposite direction is the rear. Arrow Y represents the left direction of the switch 2. The opposite direction is the right direction. Arrow Z represents the top of the switch 2. The opposite direction is the bottom. As shown in Figure 1, the switch 2 comprises a body 4, a pressure bar 6, a terminal block 14, a terminal stay 16, a filler 20, a harness 22, an auxiliary guide 42, and a fixing device 44. The body 4, terminal block 14, and terminal stay 16 constitute the main body of the switch 2. In Figure 1, the dashed line C represents the centerline of the main body. When the switch 2 is screwed into a mounting location such as a transmission, the main body rotates around the centerline C.

[0012] Figures 2 and 3 are partial exploded perspective views of the switch 2 in Figure 1. Figures 2 and 3 together form an exploded view showing the entire switch 2 in Figure 1. Figure 4 is a cross-sectional view along line IV-IV in Figure 1. However, in Figure 4, part of the harness 22, the auxiliary guide 42, and the fixing device 44 are omitted. As shown in Figures 2 and 3, the switch 2 further includes a pair of terminals 18, a conductor 8, a spring base 10, and a spring 12 inside the main body.

[0013] The body 4 is generally cylindrical. The body 4 has a cavity inside. In this embodiment, the body 4 comprises an upper part 4a and a lower part 4b. As can be seen from Figure 2, in plan view, the upper part 4a is approximately hexagonal and the lower part 4b is approximately circular. Threads are formed on the side of the lower part 4b, which are used when attaching the switch 2 to a transmission or the like. The top surface of the body 4 is open. The body 4 has an opening on the top. As shown in Figure 4, the body 4 also has an opening on the bottom. The body 4 is typically made of metal. A preferred material for the body 4 is carbon steel. The material of the body 4 may be stainless steel. The material of the body 4 may be a resin composition.

[0014] The pressing bar 6 is located inside the lower part 4b of the body 4. As shown in FIG. 4, the pressing bar 6 penetrates the lower part 4b. As shown in FIGS. 1 and 4, the tip of the pressing bar 6 is exposed from the opening on the lower side of the body 4. The pressing bar 6 is not fixed to the body 4. The pressing bar 6 is movable with respect to the body 4. The pressing bar 6 typically consists of a resin composition or metal. Examples of preferred materials for the pressing bar 6 include oil-resistant resins such as 66 nylon if it is a resin composition, and carbon steel if it is metal. When the pressing bar 6 is made of metal, an insulator for insulating from the conductor 8 is provided between the pressing bar 6 and the conductor 8.

[0015] The conductor 8 is located at the upper end of the pressing bar 6. As shown in FIG. 2, the conductor 8 includes a base 8a and a pair of wing portions 8b. The base 8a is ring-shaped. Each wing portion 8b extends upward from the base 8a. The base 8a and the wing portions 8b are integrally formed. The conductor 8 has a leaf spring structure in which the wing portions 8b are bent with respect to the base 8a. The conductor 8 is conductive. An example of a preferred material for the conductor 8 is phosphor bronze. The material of the conductor 8 may also be stainless steel or an aluminum alloy. In this specification, when a substance is "conductive", it means that the electrical conductivity of the substance is 10 6 S / m or more. Here, "S" represents the reciprocal (siemens) of the resistance "Ω (ohm)", and "m" represents the distance (meter).

[0016] The spring base 10 is located on the base 8a of the conductor 8. The spring base 10 is located between the pair of wing portions 8b. The spring base 10 is cylindrical. The spring base 10 typically consists of a resin composition. Examples of preferred materials for the spring base 10 include oil-resistant resins such as 66 nylon.

[0017] The pressing bar 6, the conductor 8, and the spring base 10 are fixed to each other. For example, when the pressing bar 6 is pushed from the outside and moves with respect to the body 4, the conductor 8 and the spring base 10 also move. Here, the pressing bar 6, the conductor 8, and the spring base 10 are collectively referred to as the "pressing unit 24". FIG. 2 shows the pressing unit 24.

[0018] As shown in FIG. 4, a spring base 10 is fitted into the lower end portion of the spring 12. A spring receiver 30 of a terminal block 14 described later is fitted into the upper end portion of the spring 12. The spring 12 keeps the spring base 10 and the terminal block 14 at a predetermined distance. Thereby, as shown in FIG. 4, the conductor 8 and the pair of terminals 18 are separated from each other and not in contact.

[0019] As shown in FIG. 2, the terminal block 14 is cylindrical as a whole and is located above the body 4 as a whole. The terminal block 14 is typically made of a resin composition. Examples of preferred materials for the terminal block 14 include PBT (polybutylene terephthalate) and 66 nylon. The material of the terminal block 14 may be PPS (polyphenylene sulfide) and PET (polyethylene terephthalate). The terminal block 14 includes a fitting portion 26, a lid portion 28, a recess 34, a pair of inner holes 32, a pair of outer holes 38, and a spring receiver 30.

[0020] The fitting portion 26 is cylindrical. As shown in FIG. 4, the fitting portion 26 has a cavity inside. The outer diameter of the fitting portion 26 is substantially equal to or slightly smaller than the inner diameter of the upper portion 4a of the body 4. The fitting portion 26 is fitted into the upper portion 4a of the body 4 from above and caulked at the upper end of the body 4. Thereby, the terminal block 14 is fixed to the body 4.

[0021] The lid portion 28 is located above the fitting portion 26. The lid portion 28 and the fitting portion 26 close the upper opening of the body 4. As shown in FIG. 1, the lid portion 28 is exposed above the body 4. The side surface 29 of the lid portion 28 constitutes a part of the outer surface of the switch 2. As shown in FIG. 4, the lid portion 28 includes a bottom 46 and a side wall 48. Thereby, as shown in FIG. 2, the recess 34 is formed on the upper surface of the lid portion 28.

[0022] Figure 5(a) is a plan view of the terminal block 14. In this embodiment, the side wall 48 has an arc-shaped portion 48a and a curved portion 48b in a plan view. In other words, in a plan view, the recess 34 has a shape that is a circle with the curved portion removed.

[0023] As shown in Figure 4, each of the pair of inner holes 32 penetrates the bottom 46. In this embodiment, the inner holes 32 extend from the bottom surface of the recess 34 to the cavity of the fitting portion 26. In this embodiment, the shape of the opening of the inner holes 32 is rectangular. As shown in Figure 5(a), each of the pair of outer holes 38 penetrates the arched portion 48b. The outer holes 38 extend from the recess 34 to the side surface 29 of the lid portion 28. In this embodiment, the shape of the opening of the outer holes 38 is circular.

[0024] The spring retainer 30 protrudes downward from the lid portion 28. The spring retainer 30 is cylindrical. As shown in Figure 4, the spring retainer 30 is fitted onto the upper end of the spring 12. In this embodiment, the spring retainer 30 is formed integrally with the lid portion 28.

[0025] As shown in Figure 2-4, the terminal stay 16 extends upward from the side 29 end (the front end in this embodiment) on the upper surface of the terminal block 14. In this embodiment, the terminal stay 16 extends upward from the curved portion 48b. The terminal stay 16 comprises an inner surface 50 located on the central side of the main body and an outer surface 52 located on the outside. In this embodiment, the terminal stay 16 has a pair of guide grooves 54 and a pair of fixing grooves 56 at both ends in the width direction (left-right direction in this embodiment), each extending from the inner surface 50 to the outer surface 52. The terminal stay 16 further has three mounting holes 58 in the center in the width direction, each penetrating from the inner surface 50 to the outer surface 52. In this embodiment, the terminal stay 16 is formed integrally with the terminal block 14. The terminal stay 16 may be formed separately from the terminal block 14.

[0026] As shown in Figure 2, in this embodiment, one of the pair of terminals 18 is obtained by rotating the other terminal 18 180° around the Z-axis, and they are substantially identical in shape. The terminal 18 comprises a contact portion 18a extending vertically and a gripping portion 18b extending horizontally from the upper end of the contact portion 18a. In this embodiment, the contact portion 18a is elongated and flat. As shown in Figure 4, each of the pair of terminals 18 is inserted into the corresponding inner hole 32. The contact portion 18a of the terminal 18 penetrates the inner hole 32. The lower end of the contact portion 18a extends to the cavity of the body 4. The gripping portion 18b is exposed on the recess 34 side of the lid portion 28. The gripping portion 18b has a slit 40 extending downward from its upper end. In this embodiment, the contact portion 18a and the gripping portion 18b are formed as a single unit. The terminal 18 is conductive. Examples of preferred materials for terminal 18 include copper and brass.

[0027] Figure 5(b) is a plan view of the terminal block 14 with the terminals 18 and harnesses 22 attached. Each of the pair of harnesses 22 is inserted into the corresponding outer hole 38. The harnesses 22 extend through the outer hole 38 into the interior of the recess 34. The harnesses 22 are passed through the slit 40 of the terminal 18. The slit 40 grips the harnesses 22. In this embodiment, the harnesses 22 are soldered to the gripping portion 18b. This electrically connects the harnesses 22 and the terminals 18.

[0028] The filler 20 is filled into the recess 34. As shown in Figure 4, the filler 20 covers the gripping portion 18b of the terminal 18. The filler 20 also covers the portion of the harness 22 that passes through the outer hole 38 and reaches the recess 34. Therefore, as shown in Figure 1, the terminal 18 and the portion of the harness 22 that reaches the recess 34 are not exposed to the outside. The filler 20 is formed by the curing of a fluid filler. In this embodiment, the filler 20 is made of a thermosetting resin. A resin that cures at room temperature may be used as the filler 20. An epoxy resin is an example of a preferred filler 20.

[0029] As shown in Figures 1 and 3, the auxiliary guide 42 is attached to the inner surface 50 of the terminal stay 16. The auxiliary guide 42 extends upward in contact with the terminal stay 16. The auxiliary guide 42 is typically made of a resin composition. Preferred materials for the auxiliary guide 42 include PBT (polybutylene terephthalate) and nylon 66. The material of the terminal block 14 may be PPS (polyphenylene sulfide) and PET (polyethylene terephthalate).

[0030] Figure 6(a) is a side view of the auxiliary guide 42, and Figure 6(b) is a rear view of the auxiliary guide 42. The auxiliary guide 42 has three protrusions 60 on its front surface. The positions of these protrusions 60 correspond to the positions of the three mounting holes 58 of the terminal stay 16. The auxiliary guide 42 is attached to the terminal stay 16 by inserting the three protrusions 60 into the corresponding mounting holes 58.

[0031] As shown in Figure 6(b), the auxiliary guide 42 is provided with a pair of lateral guide grooves 62 at both ends in the width direction, each extending in the front-rear direction. The positions of these lateral guide grooves 62 correspond to the positions of the guide grooves 54 of the terminal stay 16. The auxiliary guide 42 is also provided with a pair of fixing grooves 64 at both ends in the width direction, each extending in the front-rear direction. The positions of these fixing grooves 64 correspond to the positions of the fixing grooves 56 of the terminal stay 16. Furthermore, the back surface of the auxiliary guide 42 is provided with a vertical guide groove 66 extending in the vertical direction.

[0032] Figure 7 is a magnified side view of the area around the terminal stay 16 of the switch 2 in Figure 1. As mentioned above, the harness 22 is exposed to the outside by passing through the outer hole 38 from the inside of the recess 34. The harness 22 is pulled in from the outside of the side surface 29 of the terminal block 14 towards the inner surface 50 of the terminal stay 16 and extends upward along the auxiliary guide 42. This routing gives the harness 22 a pull-out section 68 (see Figure 5b), a main section 70, and an intermediate section 72 that connects the pull-out section 68 and the main section 70.

[0033] The pull-out portion 68 extends from the inside of the recess 34 to the outside of the side surface 29. As shown in Figure 7, the intermediate portion 72 passes through the guide groove 54 of the terminal stay 16 and the lateral guide groove 62 of the auxiliary guide 42. Guided by these grooves, the intermediate portion 72 extends from the outside of the side surface 29 of the terminal block 14 to the inner surface 50 of the terminal stay 16. The main portion 70 extends upward along the inner surface 50 of the terminal stay 16 via the auxiliary guide 42. The main portion 70 passes through the vertical guide groove 66 of the auxiliary guide 42. The tip of the main portion 70 constitutes the external terminal of this switch 2. The tip of the main portion 70 is connected to an external circuit.

[0034] Figure 8 is a plan view of switch 2 in Figure 1. As shown in Figure 8, in plan view, each main part 70 is located inside the outer edge 76 of the terminal block 14 (the outer edge of the portion exposed to the outside of the terminal block 14; in this embodiment, the outer edge of the cover 28). In this embodiment, the main part 70 is located near the center line C of the main body.

[0035] The fastener 44 secures the pair of harnesses 22 to the terminal stay 16 and the auxiliary guide 42. In this embodiment, the fastener 44 is a cable tie. As shown in Figure 7, the fastener 44 is wrapped around the terminal stay 16, the auxiliary guide 42 and the harnesses 22 at the location of the fixing grooves 56 of the terminal stay 16 and the auxiliary guide 42. The fastener 44 tightens the terminal stay 16, the auxiliary guide 42 and the harnesses 22 from the outside.

[0036] In the assembly of this switch 2, the pressing bar 6, conductor 8, and spring base 10 are combined to prepare the pressing unit 24. Furthermore, the body 4, spring 12, terminal block 14, terminal stay 16, terminal 18, harness 22, auxiliary guide 42, and fixing device 44 are prepared. As shown in Figure 2, the pressing unit 24 is inserted into the body 4 through the opening in the body 4 (S1), and then the spring 12 is attached to the spring base 10 (S2). The terminal block 14 is fitted into the body 4 (S3), and each of the pair of terminals 18 is inserted into the corresponding inner hole 32 (S4). The pair of harnesses 22 are passed through their corresponding outer holes 38, and then through the slits 40 of the gripping portion 18b of the corresponding terminal 18 (S5). A fluid filler is poured into the recess 34 of the lid portion 28, filling the recess 34 (S6). In this embodiment, heating causes the fluid filler to harden, forming the filler body 20. The intermediate switch (referred to as the intermediate body 74) formed in the process up to this point is shown in Figure 3.

[0037] Next, as shown in Figure 3, the auxiliary guide 42 is attached to the intermediate body 74 (S7). The harness 22 is bent so that it is pulled towards the inner surface 50 of the terminal stay 16, and then bent again so that it extends upward (S8). The fixing device 44 is attached around the terminal stay 16, the auxiliary guide 42, and the harness 22 (S9). This completes the assembly of the switch 2.

[0038] Switch 2 can be switched on / off as follows: In the state shown in Figure 4, switch 2 is off. When an upward force is applied to the tip of the pressure bar 6, an upward force is applied to the spring 12 via the spring base 10. The spring 12 is compressed, and the pressure unit 24 moves upward. From the state shown in Figure 4, the conductor 8 moves upward, causing each wing portion 8b to come into contact with the corresponding terminal 18. Both terminals 18 come into contact with the conductor 8. As a result, the pair of terminals 18 become electrically connected, and switch 2 turns on. When the force applied to the tip of the pressure bar 6 is removed, the pressure unit 24 is pushed back downward by the spring 12. As shown in Figure 4, the wing portions 8b and the terminals 18 separate. The pair of terminals 18 become disconnected, and switch 2 returns to the off state. The pressure bar 6 functions as a "push button" for switching between continuity and disconnection between a pair of terminals 18. The pressure unit 24 and spring 12 constitute a switching mechanism for switching between continuity and disconnection between the pair of terminals 18.

[0039] The effects and advantages of this embodiment will be explained below.

[0040] In this embodiment of switch 2, the main part 70 is located inside the outer edge 76 of the terminal block 14 in a plan view. Therefore, when the main body rotates, the rotation radius of the tip of the main part 70 that is connected to the external circuit is small. The variation in the position of the tip of the harness 22 depending on the rotation stopping position is small. With this switch 2, it is possible to connect the tip of the harness 22 to the external circuit while suppressing slack, regardless of the rotation stopping position of the main body. With this switch 2, improper mounting and slack of the harness 22 are suppressed.

[0041] In this embodiment, the harness 22 is provided with a lead-out portion 68 that extends from the inside of the recess 34 to the outside of the side surface 29. The lead-out portion 68 passes through an outer hole 38 provided in the side wall 48 of the terminal block 14. In this structure, when installing the harness 22, the outer hole 38 guides the harness 22, making it easy to connect the lead-out portion 68 to the terminal 18. This switch 2 is easy to manufacture.

[0042] In this embodiment, an auxiliary guide 42 is provided as a separate component from the terminal stay 16. This allows the terminal stay 16 to be made thinner, so that it does not get in the way when, for example, attaching the terminal 18 to the terminal block 14 or when filling with a fluid filler. This switch 2 is easy to manufacture. Furthermore, in this structure, by adjusting the thickness of the auxiliary guide 42, the main part 70 can be positioned near the center line C of the main body. This makes it possible to further reduce the variation in the tip position of the harness 22 due to the stopping position of the rotation of the main body. Regardless of the stopping position of the rotation of the main body, it is possible to connect the harness 22 to the external circuit while suppressing slack. In this switch 2, improper mounting and slack of the harness 22 are suppressed.

[0043] In Figure 8, the double arrow D1 represents the distance between the center of one main section 70 and the center line C at the tip of one main section 70. The double arrow D2 represents the distance between the center of the other main section 70 and the center line C at the tip of the other main section 70. The double arrow R represents the distance between the center line C and the outer edge 76 of the terminal block 14. If the distance between the center line C and the outer edge 76 of the terminal block 14 differs depending on the position of the outer edge 76, the maximum value among these will be distance R.

[0044] Distances D1 and D2 are preferably 1 / 2 or less of distance R. By setting distances D1 and D2 to 1 / 2 or less of distance R, the variation in the tip position of the harness 22 due to the stopping position of the main unit's rotation can be further reduced. Regardless of the stopping position of the main unit's rotation, it is possible to connect the harness 22 to the external circuit while suppressing slack. In this switch 2, improper mounting and slack of the harness 22 are effectively suppressed. From this viewpoint, distances D1 and D2 are more preferably 1 / 3 or less of distance R, and even more preferably 1 / 5 or less.

[0045] In this embodiment, the terminal stay 16 has a guide groove 54 that guides the harness 22 from the outside of the side surface 29 of the terminal block 14 to the inside surface 50 of the terminal stay 16. This allows the harness 22 to be easily pulled from the outside of the side surface 29 to the inside surface 50 of the terminal stay 16. This switch 2 is easy to manufacture.

[0046] In this embodiment, a fixing device 44 is provided to secure the main part 70 to the terminal stay 16. The fixing device 44 effectively prevents the main part 70 from shifting from its predetermined position. In this switch 2, improper mounting and sagging of the harness 22 are suppressed.

[0047] Figure 9 is a perspective view showing a switch 80 according to another embodiment. In Figure 9, arrow X represents the front of the switch 80. The opposite direction is the rear. Arrow Y represents the left direction of the switch 80. The opposite direction is the right direction. Arrow Z represents the top of the switch 80. The opposite direction is the bottom. As shown in Figure 9, the switch 80 comprises a body 82, a pressure bar 84, a terminal block 86, a terminal stay 88, a filler 90, a harness 92, and a fixing device 94. In this switch 80, the structure from the top surface of the terminal block 86 downwards is the same as that of switch 2 in Figure 1, including the internal structure which is not shown.

[0048] As shown in Figure 9, the switch 80 does not have an auxiliary guide. The main portion 96 of the harness 92 extends upward along the terminal stay 88, while in contact with the terminal stay 88. The fastener 94 is wrapped around the terminal stay 88 and the harness 92. The fastener 94 tightens the terminal stay 88 and the harness 92 from the outside.
