The effect of the photoelectric sensor 1 that present embodiment is related is as follows.In this photoelectric sensor 1, light-emitting component 211, photo detector 221 are integrated with closure 25.Therefore, can integratedly the sensor circuit assembly 2 that comprises light-emitting component 211, photo detector 221 and closure 25 be arranged on support 3.And, because the first～four splicing ear 26～29 is crimped on respectively on electric wire 61～64, so do not need welding.Therefore, in the time of can reducing worker.
And, owing to not needing welding, therefore, even the distance between closure 25 and first～the 4th splicing ear 26～29 is little, also can prevent the thermal impact to circuit part 23 and closure 25.According to this formation, can improve reliability.Also have, because the front end of the first～four splicing ear 26～29 configures down, therefore, move towards below by making sensing body circuit unit 2, can easily the first～four splicing ear 26～29 be crimped on electric wire 61～64.As mentioned above, in the photoelectric sensor 1 that relates to the present embodiment, reliability is high and easily realize miniaturization, and can reduce worker the time.
Particularly, when configuring a plurality of splicing ear side by side as in the present embodiment, in small-sized photoelectric sensor, the distance between splicing ear becomes very little.Now, be difficult for welding electric wire on each splicing ear, the adjacent problems such as splicing ear short circuit likely occur.But, in present embodiment, in related photoelectric sensor 1, because a plurality of splicing ears 26～29 are connected with electric wire 61～64 by crimping, therefore, can solve problem as above.
Also have, because the first splicing ear 26 has the first press section 260, but by pressing first press section 260 crimping the first splicing ears 26.Therefore, with the situation of pressing closure for crimping, compare, can suppress the burden to closure 25.According to this formation, can further improve reliability.
Each splicing ear 26～29, outstanding to front-rear direction from closure 25, and have towards the shape of below bending.Therefore, the press section 260,270,280,290 of each splicing ear 26～29 has been configured in from the crimping direction projection outside the zone of closure 25.Therefore, press the press section 260,270,280,290 o'clock of each splicing ear 26～29 from top, closure 25 is difficult to become obstruction.According to this formation, can easily carry out crimping.And, the part of the thickness direction end face of the thickness of slab that pressure contact portion 260,270,280,290 is splicing ear 26～29.Therefore, can easily form press section 260,270,280,290.Also have, be provided with press section 260,270,280,290 on each splicing ear 26～29.Therefore, compare when only on part splicing ear 26～29, press section being set, can press equably each splicing ear 26～29.According to this formation, each splicing ear 26～29 of crimping accurately.
Crimping is by the first～four splicing ear 26～29 is pressed to electric wire 61～64, and the endothelium that makes the first～four splicing ear 26～29 wear out electric wire 61～64 contacts with heart yearn.Therefore, do not need to cut off in advance the endothelium of electric wire 61～64, i.e. easily crimping.According to this formation, in the time of can reducing worker.
A plurality of cable holding section 311～314 is spaced mutually.Therefore, can prevent the contact of electric wire 61～64.
A plurality of cable holding section 311～314 extends along fore-and-aft direction.Therefore, when manufacturing photoelectric sensor 1, electric wire 61～64 configures along fore-and-aft direction in cable holding section 311～314.And, move and press to electric wire 61～64 towards below by making splicing ear 26～29, can easily carry out the crimping of splicing ear 26～29.
The width of the first insert port 311c of the first cable holding section 311 is less than the diameter d of electric wire 61 2.Therefore, can improve the confining force to electric wire 61 of the first cable holding section 311., electric wire 61 is difficult to come off from the first cable holding section 311.And, while by the first insert port 311c, electric wire 61 being inserted to the first cable holding section 311, can obtain and insert sense.According to this formation, when manufacturing photoelectric sensor 1, the operator can easily hold whether completed the installing wire to cable holding section.About the second～four cable holding section 312～314, also there is the effect identical with the first cable holding section 311.
The first～four terminal accommodation section 316～319 is spaced mutually.Therefore, can prevent that adjacent splicing ear from contacting.
The first terminal accommodation section 316 is configured to and the first cable holding section 311 quadratures.Now, by the first splicing ear 26 is inserted to the first terminal accommodation section 316, can easily the first splicing ear 26 be thrust in the electric wire 61 be configured in the first cable holding section 311.About the second～four splicing ear 27～29, also there is the effect identical with the first splicing ear 26.
The first splicing ear 26 is configured between a pair of the first 316a of wall section, 316b.Therefore, the distortion of the first splicing ear 26 during crimping is limited by a pair of the first 316a of wall section, 316b.Form according to this, can guarantee significantly the crimp strength of the first splicing ear 26 and electric wire.About the second～four splicing ear 27～29, also there is the effect identical with the first splicing ear 26.
In the first terminal accommodation section 316, the first projection 316c is outstanding towards the otch 267 of the first splicing ear 26.Therefore, when crimping, the heart yearn 612 of electric wire 61 is pressed in the otch 267 of the first splicing ear 26 by the first projection 316c.Therefore, in the time of can preventing crimping, heart yearn 612 is thrown off from the otch 267 of the first splicing ear 26.Form according to this, can accurately guarantee being connected of the first splicing ear 26 and heart yearn 612.About the second～four splicing ear 27～29, also there is the effect identical with the first splicing ear 26.
At splicing ear 26～29, be configured under the state with the position of electric wire 61～64 crimping, the first engaging portion 37 and the second engaging portion 38 arrive the position with 2 engagings of sensor circuit assembly.Therefore, due to the first engaging portion 37 and the second engaging portion 38 engagings on sensor circuit assembly 2, thereby can firmly maintain the crimping of the first～four splicing ear 26～29 and electric wire 61～64.And, when crimping, when the first～four splicing ear 26～29 is configured in the position with electric wire 61～64 crimping, the first engaging portion 37 and the second engaging portion 38 arrive the position with 2 engagings of sensor circuit assembly.Therefore, the operator, by the first engaging portion 37 and the second engaging portion 38 situation of engaging on sensor circuit assembly 2, can easily hold the crimping that whether completes the first～four splicing ear 26～29.
Luminous leading part 242 be subject to light leading part 243 crooked upward.The first～four splicing ear 26～29 is crooked downwards.Therefore, when pressing the first～four splicing ear 26～29 downwards and being crimped on electric wire 61～64, luminous leading part 242 be subject to light leading part 243 can not hinder crimping.
In first sidepiece 252 and the second sidepiece 253 of closure 25, the first～four splicing ear 26～29 only is arranged on the first sidepiece 252.In the situation that on both of the first sidepiece 252 and the second sidepiece 253, splicing ear is set, the mode that need to balancedly apply with the splicing ear of the splicing ear to the first sidepiece 252 and the second sidepiece 253 power is carried out crimping, but and is not easy.And, for the splicing ear of the splicing ear to the first sidepiece 252 and the second sidepiece 253 balancedly applies power, the closure 25 of pressing between the first sidepiece 252 and the second sidepiece 253 is comparatively effective, but likely damages closure 25.On the contrary, as shown in the embodiment, by the first～four splicing ear 26～29 only is set on the first sidepiece 252, can be easily even a plurality of splicing ears 26～29 of crimping.
The width of the first joint portion 262 of the first splicing ear 26 is less than the width of the first pressure contact portion 261.Therefore, when identical with the width of the width of the first joint portion 262 and the first pressure contact portion 261, compare, can crooked the first splicing ear 26 of enough less power.Similarly, to the second～four splicing ear 27～29, also can enough less power bendings.Therefore, when carrying out the bending machining of the first～four splicing ear 26～29, can reduce the related power of closure 25 of sensor circuit assembly 2.Form the breakage of the closure 5 in the time that bending machining can being prevented according to this.And, can enough less power bendings first～the 4th splicing ear 26～29, can improve the accuracy of the angle of bend of the first～four splicing ear 26～29.
The first press section 260 is outstanding from the surface of the first terminal accommodation section 316.Therefore, when crimping the first splicing ear 26, can easily press the first press section 260.Thus, can easily the first splicing ear 26 be crimped on electric wire 61.About the second～four splicing ear 27～29, also have and the identical effect of the first splicing ear 26.
The width w3 of the otch 267 of the first splicing ear 26 is less than the width w7 of the bundle of the heart yearn 612 that there is no crimping.Now, due to heart yearn 612 to be bundled in otch 267 interior by the first splicing ear 26 clamping, thereby can firmly connect heart yearn 612 and the first splicing ear 26.About the second～four splicing ear 27～29, also there is the effect identical with the first splicing ear 26.
The inner surface in the hole 35 of support 3 has the first～four projection 354～357.Therefore, can guarantee that by the first～four projection 354～357 gap between the outer surface of the inner surface in hole 35 and cable 6 is even.Therefore, when being bonded on hole 35 by cable 6, can make equably between binding agent ostium 35 and cable 6.Form according to this, can improve the adhesion strength of cable 6.
In the hole 35 of support 3, the internal diameter of the second hole section 352 is larger than the internal diameter of the first hole section 351.And towards hole, 35 end direction becomes large to the internal diameter of the second hole section 352.Therefore, binding agent is easy between ostium 35 and cable 6.Form according to this, can reduce the generation of bonding defect.
The location division 36 of support 3 is configured to above hole 35 overlapping with the part in hole 35.Therefore, can easily carry out the location of upper end of the crust 60 of cable 6.And location division 36 is parts of the first wall section 31.Therefore, the first wall section 31 can be doubled as to location division 36 uses.
The area of light emission lens section 212 is different from the area of sensitive lens section 222.Therefore, the area of the area of light emission lens section 212 and sensitive lens section 222 can be set respectively for to the size that is applicable to light-emitting component 211 and photo detector 221.And, because light-emitting component 211 and photo detector 221 are arranged on the lead frame 24 of one, therefore, when manufacturing sensor circuit assembly 2, can carry out the moulding of light emission lens section 212 and sensitive lens section 222 simultaneously.Therefore, even the area of light emission lens section 212 is different from the area of sensitive lens section 222, also without using different moulds, can carry out the moulding of light emission lens section 212 and sensitive lens section 222 by enough common moulds.According to this formation, in the time of can reducing worker and cost.
Although cable 6 is by making it towards support 3, move up and be installed on support 3, sensor circuit assembly 2 is by making it towards support 3, move down and be installed on support 3.And auxiliary shell 4 and main body cover 5 are also by making it towards support 3, move down and be installed on support 3.Therefore, after being arranged on support 3 by cable 6, successively sensor circuit assembly 2, auxiliary shell 4 are assembled on support 3 with main body cover 5 in the same direction.Form according to this, can easily carry out the assembling of photoelectric sensor 1.
Above, an execution mode of the present utility model is illustrated, but the utility model is not limited to above-mentioned execution mode, can carry out various changes within not breaking away from the spiritual scope of utility model.
