(2.2) Wiring structure of electric wire

Next, reference picture 1, Fig. 7 A and Fig. 7 B, are described in more detail the electricity imported from introducing port 101 into housing 1 The Wiring structure of line 3.Fig. 7 A, Fig. 7 B are by the stereogram after the critical piece amplification for the state for having pulled down lid 12.

Electric wire 3 is directed in housing 1 from the introducing port 101 for the upper end for being formed at housing 1.In housing 1, electric wire 3 The 2nd connection end 32 be connected with socket main body 2.Herein, housing 1 has the exterior space with housing 1 using introducing port 101 Connected spiral accommodation space 131.As described above, spiral accommodation space 131 is under the spiral portion 33 in containing electric wire 3 The space of end 331.I.e., in the suspension type socket 10 of present embodiment, electric wire 3 is with the bottom 331 at least spiral portion 33 The mode being accommodated in housing 1, it is imported into from introducing port 101 in housing 1.

The bottom 331 in spiral portion 33 is the part in spiral portion 33, has and is circled round like that around central axis Z1 Shape.Therefore, in the present embodiment, in the plane (horizontal plane) orthogonal with vertical, formed with spiral portion 33 Central axis Z1 around the lead-in path P1 of shape that circles round, electric wire 3 is imported into housing 1 by lead-in path P1 It is interior.Lead-in path P1 is the path of electric wire 3, and spiral accommodation space 131 is connected with the exterior space of housing 1.Moreover, introducing port 101 form on lead-in path P1.Thus, as indicated by arrow a 1, so that the side that electric wire 3 circles round around central axis Z1 Formula, rear surface of the electric wire 3 along lead-in path P1 from housing 1 is imported in housing 1.Therefore, housing 1 is able to maintain that spiral portion The bottom 331 in spiral portion 33 is accommodated in 33 shape spiral accommodation space 131.In the present embodiment, do not utilize and divide Next door etc. separates lead-in path P1 from the space physics of surrounding.But it is also possible to using partition wall etc. by lead-in path P1 Separated from the space physics of surrounding.Fig. 7 A lead-in path P1 only in explanation clear and definite electric wire 3 path, not generation Table entity.Equally, Fig. 7 B arrow A1 only conceptually represents the feelings that electric wire 3 is imported into housing 1 from introducing port 101 Condition, do not represent entity.

Herein, though the bottom 331 in spiral portion 33 is the part in spiral portion 33, because being accommodated in housing 1, So also turn into the shape for receiving the influences such as the width of inner space 13 of housing 1.Therefore, the bottom 331 in spiral portion 33 Both can be with the position beyond the bottom in spiral portion 33 331 be same helical form or for example with spiral portion 33 Position different-diameter beyond bottom 331 etc., shape that helical form is somewhat collapsed.

Specifically, housing 1 has a guide surface 105, the guide surface 105 from the left border of the introducing port 101 of seat body 11 to Rear protrudes, and is bent in a manner of the width of the left and right directions of introducing port 101 more rearward is wider.Thus, relative to leading In the outside of housing 1 formed with lead-in path P1 for entrance 101, lead-in path P1 with along guide surface 105 in central shaft The mode of line Z1 surrounding convolution is bent.

In addition, housing 1 has clamping part 106, the clamping part 106 in spiral accommodation space 131 by clamping spiral portion A part for 33 bottom 331, so as to keep the bottom 331 in spiral portion 33.In the present embodiment, clamping part 106 by Formed positioned at the 1st holding piece 113 of the both sides of lead-in path P1 fore-and-aft direction and the 2nd holding piece 126 (reference picture 6).1st folder Hold piece 113 and be arranged at the holding piece 126 of a body the 11, the 2nd and be arranged at lid 12.1st holding piece 113 and the 2nd holding piece 126 are in right and left Upwards between introducing port 101 and central axis Z1.Moreover, the top ends (leading section) of the 1st holding piece 113 are from seat body 11 Preceding surface (opening surface) protrudes forwards.On the other hand, the top ends (rearward end) of the 2nd holding piece 126 are located at not from lid 12 Afterwards surface (opening surface) prominent position, i.e. than the rear surface position on the front of lid 12.Thus, portion 106 is clamped to be kept Spiral portion 33 bottom 331 with from introducing port 101 along the inner surface of lid 12 central axis Z1 inner peripheral surface around great circle Mode, in the cabling of spiral accommodation space 131.Therefore, in the inner side of the housing 1 relative to introducing port 101, (namely spiral is received Receive space 131) formed with lead-in path P1, lead-in path P1 by clamping part 106 and in central axis Z1 surroundings to circle round Mode bend.

But as described above, spiral accommodation space 131 is stored by transit space 133 and winding space 134 with socket Space 132 is connected.Moreover, transit space 133 has the entrance 135 being connected with spiral accommodation space 131 and stored with socket empty Between 132 connected outlets 136.In the present embodiment, entrance 135 is joined directly together with spiral accommodation space 131, and outlet 136 is borrowed Winding space 134 is helped to be connected with socket accommodation space 132.In the present embodiment, transit space 133 is located at than central axis Z1 The position for the side of keeping left, entrance 135 are located at central axis Z1 left.Herein, entrance 135 is formed from a pair of housing 1 and entered Space between mouth projection 114 is formed.The space that outlet 136 is formed between a pair of outlet projections 115 of housing 1 is formed. A pair of entrance projections 114 and a pair of outlet projections 115 are kept as clamping part 106 by clamping a part for electric wire 3 Electric wire 3.

A pair of entrance projections 114 are located at the left of spiral accommodation space 131.A pair of entrance projections 114 in above-below direction simultaneously Row arrangement.Thus, the entrance 135 of transit space 133 by make electric wire 3 along the direction intersected with above-below direction the structure in a manner of Into.In the present embodiment, the relative direction of a pair of entrance projections 114 is not parallel relative to above-below direction, the entrance of upside Projection 114 is positioned at the upper left side of the entrance projection 114 of downside.Therefore, by the electric wire 3 of the entrance 135 of transit space 133 from volume Line accommodation space 131 passes through between a pair of entrance projections 114 towards lower left.

On the other hand, a pair of outlet projections 115 are positioned at the lower section of a pair of entrance projections 114.A pair of outlet projections 115 are on a left side It is arranged side-by-side in right direction.Thus, the outlet 136 of transit space 133 by make electric wire 3 along above-below direction the structure in a manner of Into.Therefore, the electric wire 3 by the outlet 136 of transit space 133 is raised by a pair of outlets downward from transit space 133 Between 115.Therefore, between the entrance 135 of transit space 133 and outlet 136, the extending direction of electric wire 3 becomes from " lower left " It is changed to " lower section ".

Moreover, the interval of a pair of outlet projections 115 is set as that the interval of than a pair of entrance projections 114 is small.In this embodiment party In formula, electric wire 3 is made up of cross sectional shape for the flat wire of flat pattern.The interval of a pair of entrance projections 114 is set as and electricity The long edge size of the cross sectional shape of line 3 is same degree.The interval of a pair of outlet projections 115 is set as the section shape with electric wire 3 The short side dimension of shape is same degree.Thus, at the entrance 135 of transit space 133, the thickness direction of electric wire 3 be (electric wire 3 The short side direction of cross sectional shape) it is direction along fore-and-aft direction.On the other hand, at the outlet 136 of transit space 133, electricity The thickness direction (short side direction of the cross sectional shape of electric wire 3) of line 3 is the direction along left and right directions.I.e., transit space 133 The thickness direction of electric wire 3 at the thickness direction of electric wire 3 at entrance 135 and the outlet 136 of transit space 133 is intersected with each other. In other words, between the entrance 135 of transit space 133 and outlet 136, electric wire 3 is made to remain the state of torsion.

In addition, in the present embodiment, a pair of entrance projections 114 and a pair of outlet projections 115 may be contained within a body 11.But It is that the top ends (leading section) of a pair of entrance projections 114 protrude forwards from the preceding surface (opening surface) of seat body 11.With this phase Right, the top ends (leading section) of a pair of outlet projections 115 are located in a manner of prominent not from the preceding surface (opening surface) of seat body 11 With preceding surface (opening surface) the substantially same plane of seat body 11.Thus, at the entrance 135 of transit space 133, a pair of entrances are convex Electric wire 3 can be kept in lid 12 by playing 114.On the other hand, at the outlet 136 of transit space 133, a pair of outlet projections 115 The body 11 that can be present is interior to keep electric wire 3.

The electric wire 3 imported from the outlet 136 of transit space 133 to winding space 134, pass through the left and right directions of reel 5 At least side, cabling to socket accommodation space 132.In the present embodiment, electric wire 3 is divided into two strands by winding space 134, passes through The both sides of the left and right directions of reel 5, cabling to socket accommodation space 132.As one, the power line and ground wire of a side pass through The left side of reel 5, the power line of the opposing party pass through the right side of reel 5, cabling to socket accommodation space 132.Stored in socket empty Between in 132, the 2nd connection end 32 as the top ends (bottom) of electric wire 3 electrically connects with socket main body 2.

(2.3) winding mechanism

Next, reference picture 1 and Fig. 8, the winding mechanism and winding mechanism of the rope body 4 using reel 5 is described in more detail Action.Fig. 8 is the sectional view of the critical piece of the state of the lid 12 for the suspension type socket 10 for having pulled down present embodiment.

As shown in figure 8, reel 5 with along centered on the axle of fore-and-aft direction (specifically, being rotary shaft 551) rotatably It is maintained in housing 1.

In addition, as described above, being configured with wind spring 62 in the inside of reel 5, reel 5 is born from wind spring 62 (the direction of the imaginary arrow B1 shown in Fig. 8 clockwise is viewed as from front；Hereinafter referred to as " first direction ") elasticity Power.

On the other hand, one end of rope body 4 is hooked in the lanyard groove 521 of reel 5 and fixed, and rope body 4 is inverse from forward observation It is wound around the 1st reel 51, the tangent line from the upper right portion of the 1st reel 51 along the 1st reel 51 is led to upper left side hour hands Go out (reference picture 1).From the derived rope body 4 of reel 5, pulled out by cord hole 102 to outside housing 1, its top ends is fixed in suspension Tectosome 9.Therefore, reel 5 bears the load production of object (housing 1 etc.) from rope body 4, being supported by acting on rope body 4 It is raw, be viewed as the counterclockwise (direction of the imaginary arrow B2 shown in Fig. 8 from front；Hereinafter referred to as " second direction ") Power.

In addition, stop part 7 is configured with housing 1.In the restriction site of stop part 7, limiting unit 73 is located at depressed part 541 It is interior.1st margining tablet 731 of limiting unit 73 and the 2nd margining tablet 732 are in depressed part 541, respectively for the right side of depressed part 541 Side and left lateral sides.

In the case where the power of the second direction from rope body 4 is smaller than the power of first direction caused by wind spring 62, volume Disk 5 is intended to rotate to first direction (Fig. 8 arrow B1 direction).Now, as shown in figure 8, the right side side of depressed part 541 and the 1 margining tablet 731 contacts, and applies the power of first direction from reel 5 to the 1st margining tablet 731.Meanwhile as the reaction force of the power, Apply the power of second direction from the 1st margining tablet 731 to reel 5.

Herein, as shown in Fig. 8, Figure 10, the 1st regulation angle between the 1st margining tablet 731 and connection sheet 733 of stop part 7 Degree θ 1 is set as less than 90 °.In addition, the angle between the right side side of depressed part 541 and the bottom surface of depressed part 541 is acute angle. Therefore, when reel 5 to be made rotates to first direction, put on from reel 5 (the right side side of depressed part 541) the 1st limitation The power of piece 731, turn into the power more upward than the tangential direction of reel 5 (the 2nd reel 54).Therefore, even if putting on the 1st from reel 5 The power of margining tablet 731 becomes big, but the power be make the 1st margining tablet 731 upward (to the central side of reel 5) displacement power, institute So that limiting unit 73 will not be made to depart from from depressed part 541.As a result, in the power from rope body 4 than the power from wind spring 62 In the case of small, for reel 5, as caused by wind spring 62 power of first direction with by the margining tablet of rope body 4 and the 1st The power of second direction caused by 731 is in balance.Thus, reel 5 does not keep the position of the vertical of housing 1 rotatably.

On the other hand, it is bigger than the power of the first direction as caused by wind spring 62 in the power of the second direction from rope body 4 In the case of, reel 5 is intended to rotate to second direction (Fig. 8 arrow B2 direction).Now, the side in the left side of depressed part 541 Contacted with the 2nd margining tablet 732, apply the power of second direction from reel 5 to the 2nd margining tablet 732.Meanwhile as the anti-work of the power Firmly, the power of first direction is applied from the 2nd margining tablet 732 to reel 5.

Herein, fixed part 71 with the tangential direction of the end of the side of limiting unit 73 of elastic portion 72 and the 2nd reel 54 substantially Parallel mode is inclined relative to horizontal predetermined angular θ A.In addition, as shown in Fig. 8, Figure 10, the 2nd margining tablet of stop part 7 732 and elastic portion 72 the side of limiting unit 73 end between the 2nd predetermined angular θ 2 be set as the value bigger than 90 °.Moreover, depression Angle between the left lateral sides in portion 541 and the bottom surface of depressed part 541 is obtuse angle.Therefore, when reel 5 will rotate to second direction , the power for putting on from reel 5 (left lateral sides of depressed part 541) the 2nd margining tablet 732 be cutting than reel 5 (the 2nd reel 54) The power that line is directed downward.Therefore, when the power that the 2nd margining tablet 732 is put on from reel 5 becomes big, because the power is to make the 2nd limitation The power of (outward direction of the radial direction of the reel 5) displacement downwards of piece 732, so, the displacement downwards of limiting unit 73 and from depressed part 541 depart from.Therefore, housing 1 is pulled downwards in user, the power for the second direction for making to put on reel 5 from rope body 4 becomes big When, the 2nd margining tablet 732 departs from from depressed part 541, and reel 5 rotates to second direction (direction of release rope body 4).

Consequently, it is possible to for the suspension type socket 10 of present embodiment, when stop part 7 is located at restriction site, prohibit Only reel 5 is rotated in a first direction and allows reel 5 to rotate in a second direction.In a word, the suspension type socket of present embodiment For 10 reel 5 in the presence of ratchet mechanism, its direction rotated is restricted to only carry out (release rope body 4 in a second direction Direction) rotation.

In addition, user implements the operation that pressing releases button 61, and when stop part 7, which is moved to, releases position, limiting unit 73 depart from from depressed part 541.Now, reel 5 will not be by the power from stop part 7, it is allowed to first direction and second direction The rotation in the two directions.Therefore, user can either utilize the recuperability of wind spring 62 to restrict body 4 in housing 1, Housing 1 is set to increase, also can be by overcoming the recuperability of wind spring 62 pull housing 1 downwards, so as to discharge rope body from reel 5 4, decline housing 1.User, which need to only leave hand, releases button 61, it becomes possible to stop part 7 is returned to restriction site, makes limit Portion 73 processed is located in the depressed part 541 of reel 5, so that limiting unit 73 limits the rotation of reel 5 again.

However, for as described previously for the suspension type socket 10 of present embodiment, stop part 7 is provided with the 2nd limitation Piece 732.2nd margining tablet 732 has following function：Limitation reel 5 to release restrict body 4 direction rotate and bear reel 5 to The revolving force that rotates of direction of release rope body 4 and make the 2nd margining tablet 732 to the outer displacement of depressed part 541.Hereinafter, in more detail Bright 2nd margining tablet 732.

In first direction of the power than putting on reel 5 from wind spring 62 for the second direction that reel 5 is put on from rope body 4 Power it is big when, the power of second direction made a concerted effort as these power puts on the 2nd margining tablet 732.For this make a concerted effort in, make 2nd margining tablet 732 is from for the composition (power of the normal direction of the 2nd reel 54) in the direction that depressed part 541 departs from, the 2nd limitation Piece 732 is relative to the angle of the tangential direction of the 2nd reel 54 closer to 90 °, and the composition is with regard to smaller.I.e., the phase of the 2nd margining tablet 732 For the 2nd reel 54 tangential direction angle closer to 90 °, limiting unit 73 is more difficult to depart from from depressed part 541.In this reality Apply in mode, in a manner of the function that there is the 2nd margining tablet 732 direction of limitation reel 5 to release rope body 4 to rotate, by the 2nd limit Film-making 732 is relative to the angle that the angle initialization of the tangential direction of the 2nd reel 54 is close to 90 °.

Herein, as shown in figure 8, stop part 7 is to make the end and the 2nd of the side of limiting unit 73 of elastic portion 72 in restriction site The almost parallel mode of the tangential direction of reel 54, makes fixed part 71 be inclined relative to horizontal predetermined angular θ A.In addition, by Angle initialization between the end of the side of limiting unit 73 of 2 margining tablets 732 and elastic portion 72 is the 2nd predetermined angular θ 2.That is, for this For the stop part 7 of embodiment, the 2nd margining tablet 732 tilts substantially in restriction site relative to the tangential direction of the 2nd reel 54 2nd predetermined angular θ 2.Moreover, in the present embodiment, the 2nd predetermined angular θ 2 size is set as than 90 ° greatly and close to 90 ° Angle.

, it is specified that angle, θ A is 15 ° in a concrete example, the 2nd predetermined angular θ 2 is 110 °.Thus, when reel 5 will be along second When direction rotates, the 2nd margining tablet 732 can suppress the rotation.I.e., applied even in the load of the recuperability more than wind spring 62 In the case of being added on housing 1, can also stop part 7 be utilized to support the load.

(2.4) protection construction

As described above, in the present embodiment, stop part 7 is provided with the 2nd margining tablet 732, even if putting on the load of housing 1 Lotus exceedes the recuperability of wind spring 62, can also utilize the 2nd margining tablet 732 to suppress the direction of reel 5 to release rope body 4 and revolve Turn.Particularly, can if increasing the width (width of fore-and-aft direction) of stop part 7 and the elastic force of elastic portion 72 is become big Enough bigger load is supported using the 2nd margining tablet 732.But now as caused by putting on the load of housing 1 power via the 2nd Margining tablet 732 puts on fixed part 71 and maintaining part 8.Therefore, the suspension type socket 10 of present embodiment also has protection construction, The protection is configured to bear to put on the power of fixed part 71 and maintaining part 8 via the 2nd margining tablet 732.Hereinafter, reference picture 8, figure 9A, Fig. 9 B and Figure 10 illustrate that the protection constructs.
