Abstract
The present invention provides a crimping device that facilitates an adjustment operation and has a reduced height. A crimping device has a crimp height adjustment mechanism for a core of a wire onto which a terminal is to be crimped and a crimp height adjustment mechanism for an insulating coating of the wire, the mechanisms having respective adjustment dials, and the front of the crimping device facing in the opposite direction of the core. In the adjustment mechanisms, the adjustment dials thereof are disposed on the same axis so that the crimping device can have a reduced height compared with conventional crimping devices in which the adjustment mechanisms are disposed at positions different in the vertical direction.
Description
- The present invention relates to a crimping device that has adjustment mechanisms that adjust the crimp heights for a core and an insulating coating, respectively, of a wire with an end stripped.
- It is desirable to have the ability to adjust the crimp height for a core and an insulated coating of a wire when a terminal is crimped onto the core and the insulating coating. Crimping devices with adjustment mechanisms for adjust the crimp heights for a core and an insulating coating of a wire with an end stripped are known. For example, Japanese Patent Laid-Open No. 7-6849, discloses a crimping device with adjustment mechanisms.
- However, in the crimping device disclosed in Japanese Patent Laid-Open No. 7-6849, operating the crimp height adjustment mechanism for a core and the crimp height adjustment mechanism for an insulating coating involves additional operations, such as loosening of a predetermined fastened part, so that it takes time to adjust the crimp heights.
- Another crimping device that has two dials for operating the two height adjustment mechanisms is disclosed in Japanese Utility Model Laid-Open No. 7-27086.
-
FIG. 1 is a front view of essential parts of the crimping device described in Japanese Utility Model Laid-Open No. 7-27086.Crimping device 1 has, on the front thereof, dials for operating the crimp height adjustment mechanism for a core and the crimp height adjustment mechanism for an insulating coating and includes a prime mover section that produces a force required for crimping and an applicator that achieves crimping of a terminal using the force produced by the prime mover section. - As shown in
FIG. 1 , thecrimping device 1 has apress ram 11, which transmits force produced by a prime mover section to anapplicator 20. Theapplicator 20 is composed of amachine casing 21, ananvil unit 22 and abase 23. A pair ofvertical rails 24 are fixed to themachine casing 21, and anoscillation beam 26 is supported on themachine casing 21 by ashaft 26 a. Atool ram 25 is guided by thevertical rails 24 to move up and down. Thetool ram 25, in cooperation with theanvil unit 22, crimps a terminal onto a strippedpart 30 a of a wire (seeFIG. 2 ). - The
tool ram 25 is connected to thepress ram 11 described above and has acam roller 25 b supported on aside section 25 a thereof by ashaft 25 c. Thecam roller 25 b is fitted into acam groove 26 b formed in theoscillation beam 26. Thus, when thetool ram 25 moves up and down, theoscillation beam 26 oscillates about theshaft 26 a. Aplate 28 is attached to a lower part of theoscillation beam 26, and afeeding claw 27, whose tip end engages with chained terminals n placed behind a terminal guide rail 23 a, is supported on theplate 28 by ashaft 27 b. -
FIG. 2 is a side view of essential parts of the crimping device shown inFIG. 1 . - A terminal n1 shown in
FIG. 2 is composed of a contact part n11, an insulation barrel n12 for holding the coating of thewire 30, and a wire barrel n13 for holding acore 32 thereof. Multiple terminals n1 are connected to a carrier n14 to constitute the chained terminals n. Acrimper section 25 d of thetool ram 25 shown also inFIG. 1 is composed of a cut-off punch 251 d, aninsulation crimper 252 d for crimping the insulation barrel n12, and awire crimper 253 d for crimping the wire barrel nl3. - In this
crimping device 1, operation of afeeding claw 27 causes the terminal n1, which is the closest to theanvil unit 22 of the plural chained terminals n, to be placed on theanvil unit 22. Then, when thewire 30 with an end previously stripped is placed on the terminal n1 on theanvil unit 22, thepress ram 11 moves downward, and thetool ram 25 connected to thepress ram 11 is guided by thevertical rails 24 to move downward. Then, thetool ram 25 and theanvil unit 22 cooperate to cut a bridge part n15, which connects the terminal to the carrier n14, and crimp the terminal n1, separated from the chained terminals n, onto the strippedpart 30 a. When the crimping is completed and thetool ram 25 begins to move upward, thecam roller 25 b also moves upward along thecam groove 26 b in theoscillation beam 26, and thus, theoscillation beam 26 oscillates about theshaft 26 a counterclockwise. This movement causes thefeeding claw 27 to place a terminal, which is the closest to theanvil unit 22 of the chained terminals n, on theanvil unit 22 along the terminal guide rail 23 a. - As shown in
FIG. 2 , theanvil unit 22 is composed of a floatingshear 221 having agroove cutting edge 221 a, aninsulation anvil 222 and awire anvil 223. When thetool ram 25 moves downward guided by thevertical rails 24, the bridge part n15 of the terminal n1 on theanvil unit 22 is cut by the cut offpunch 251 d and thegroove cutting edge 221 a of thefloating shear 221, and the insulation barrel n12 is crimped onto thecoating 31 of thewire 30 by theinsulation crimper 252 d and theinsulation anvil 222. In addition, the wire barrel n13 is crimped onto thecore 32 of thewire 30 by thewire crimper 253 d and thewire anvil 223. - Here, in the
crimping device 1 shown inFIGS. 1 and 2 , the crimp heights for the core and the coating are adjusted by changing the bottom dead centers of thewire crimper 253 d and theinsulation crimper 252 d, respectively. In thecrimping device 1, the bottom dead centers are changed by rotating thedials FIGS. 1 and 2 . Theupper dial 50 is for the wire crimper, and thelower dial 40 is for the insulation crimper. Adjustment operations can be achieved by manipulating the dials of the adjustment mechanisms. - In accordance with the recent trend toward downsizing, there is a demand for downsizing of the crimping devices for crimping a terminal onto a stripped part of a wire. However, the
crimping device 1 disclosed in the above Japanese Utility Model Laid-Open No. 7-27086 is difficult to reduce in height. - According to an exemplary embodiment of the invention, a crimping device is provided that has a crimp height adjustment mechanism for a core of a wire onto which a terminal is to be crimped and a crimp height adjustment mechanism for an insulating coating of the wire, the mechanisms having respective adjustment dials, and the front of the crimping device facing in the opposite direction of the core, in which the adjustment mechanisms are disposed on a same axis, and the adjustment dials of the adjustment mechanisms are disposed on the front of the crimping device.
- Since the adjustment dials of the crimping device according to the present invention is disposed facing to the operator, the crimp height adjustment can be readily achieved. In addition, since the crimp height adjustment mechanism for a core and the crimp height adjustment mechanism for an insulating coating are disposed on the same axis, the adjustment dials of the two adjustment mechanisms are also disposed on the same axis. Therefore, the crimping device according to the present invention can have a reduced height compared with conventional crimping devices that have the adjustment dials at positions different in the vertical direction.

crimping device 100 according to the embodiment of the present invention shown inFIG. 3 has ahousing section 101 that contains a prime mover (not shown) that drives apress ram 11, and anapplicator section 102 that is attached to thehousing section 101 and crimps a terminal onto a stripped end part of a wire using the force from thepress ram 11. -
FIG. 4 is a schematic view of the applicator section of the crimping device shown inFIG. 3 , viewed from the front thereof. - For the
applicator section 102, shown inFIG. 4 , a terminal (not shown) is fed thereto from the left in the drawing, and a wire (not shown) with an end stripped to expose the core is fed thereto from the front in the drawing. As described in detail later, in theapplicator section 102, a crimp height adjustment mechanism for a core and a crimp height adjustment mechanism for an insulating coating are disposed on an axis of adial 140 shown inFIG. 4 . - The
applicator section 102 shown inFIG. 4 essentially has amachine casing 121, atool ram 125 that moves up and down with respect to themachine casing 121, ananvil unit 122, and abase 123. Themachine casing 121 has avertical rail 124 attached thereto, along which thetool ram 125 moves up and down. - In addition, the
machine casing 121 has aside plate 130 with anelongated hole 130 a formed therein. Ashaft 132 is provided between themachine casing 121 and a supportingmember 133 attached to the housing section 101 (seeFIG. 3 ) located to the left inFIG. 4 . - The
shaft 132 has a cam follower (not shown) provided thereon, which engages with a cam groove formed in a predetermined surface of thetool ram 125 to allow theshaft 132 to reciprocate in a horizontal direction inFIG. 4 in response to thetool ram 125 moving up and down. - A
claw section 127 feeds one of a plurality of chained terminals n, which is the closest to theanvil unit 122, to theanvil unit 122. Anarm 127 b of theclaw section 127 is connected to theshaft 132 and has ashaft 1271 b passing through theelongated hole 130 a. Theside plate 130 has acomposite nut 131 having acenter section 131 a and aperipheral section 131 b attached thereto at the center of theelongated hole 130 a. An end of theshaft 1271 b of thearm 127 b is press-fitted to thecenter section 131 a of thecomposite nut 131. Thecenter section 131 a of thecomposite nut 131 can rotate with respect to theperipheral section 131 b. Thus, when theshaft 132 moves in a horizontal direction inFIG. 4 in response to thetool ram 125 moving up or down, thearm 127 b rotates about thecenter section 131 a of thecomposite nut 131 to move aclaw 127 c via alink section 127 a connected thereto, and theclaw 127 c feeds a terminal to theanvil unit 122. - In addition,

Acrimper section 125 d is provided for achieving crimping in cooperation with theanvil unit 122 that is located directly below the dial and composed of a cut-off punch 1251 d and aninsulation crimper 1252 d and the like. - The
anvil unit 122 has a floatingshear 1221 that separates a leading one from the chained terminals in cooperation with the cut-off punch 1251 d. The anvil unit further includes an insulation anvil that achieves crimping in cooperation with theinsulation crimper 1252 d or the like, although the insulation anvil is not shown inFIG. 4 . Furthermore,FIG. 4 shows anabutment plate 126 located above theanvil unit 122, against which the tip end of the core of the stripped wire abuts for positioning of the wire. -

In the lower area ofFIG. 5 , a cut-off punch 1252, aninsulation crimper 1253, aflat washer 1256, aspacer 1257 and awire crimper 1254 are attached by ahexagonal screw 1251 to a lower part of amain section 1250 of thetool ram 125. In the middle area ofFIG. 5 , acrimper support 1255 is attached to the middle of themain section 1250 by ascrew 1258. In the upper area ofFIG. 5 , thewire dial 140 is fitted into ahole 1250 a formed in an upper area of themain section 1250 through aspring 160 and aninsulation dial 150. Apin 1259 is inserted directly above thehole 1250 a. - A
pin 1261 and aspring 1260 constituting a plunger and fitted into the bottom of thehole 1250 a are shown directly above themain section 1250. Anupper edge 1254 a of thewire crimper 1254 abuts against the bottom of ajaw 1255 b of thecrimper support 1255. Theflat washer 1256 is thicker than theinsulation crimper 1253 and is fitted into anelongated hole 1253 a formed in the middle of theinsulation crimper 1253. Thus, theinsulation crimper 1253 can move vertically with respect to themain section 1250. - The
wire dial 140 has a substantially cylindrical shape. The outer circumference of the main body of the wire dial, excluding afront dial plate 140 a with numerics inscribed, is constituted by, from the dial plate toward the depth thereof, asection 141 that is surrounded by thecoil spring 160 and theinsulation dial 150, afitting section 142 that is a groove which is formed over the total circumference of the wire dial and into which aprotrusion 1255 a of thecrimper support 1255 is fitted, and apolyhedron section 143 that is cut so that different points on the circumference are at different distances from the center of the wire dial. In the middle of eachsurface 143 a of thepolyhedron section 143, a shallowconical hole 144 is formed into which thepin 1261 of the plunger is fitted to secure the surface when the surface is selected. - The
insulation dial 150 is a short component having a substantially cylindrical shape and has a polyhedron outer circumference. While the distance between the center axis and the inner circumference of theinsulation dial 150 is constant, the distance between the center axis and the outer circumference varies with the position along the circumference. That is, the thickness of theinsulation dial 150 varies with the point along the circumference. When rotating theinsulation dial 150, theinsulation dial 150 is pulled toward the dial plate of thewire dial 140 against the biasing force of thecoil spring 160. When theinsulation dial 150 is released, thepin 1259 protruding slightly from themain section 1250 of thetool ram 125 is fitted into avalley 151 formed in an edge of theinsulation dial 150, thereby securing the rotational position of theinsulation dial 150. - Now, the crimp height adjustment mechanism for a core and the crimp height adjustment mechanism for an insulating coating, which are provided on a same axis according to this embodiment, will be described with reference to
FIG. 6 . -
FIG. 6 is a partial cross sectional side view of an upper part of the tool ram, part of which is shown as a side view. Specifically, the crimper part is shown as a side view. In this drawing, cross sections of theinsulation dial 150 are shown above and below the cross section of thewire dial 140, and theupper edge 1253 b of theinsulation crimper 1253 abutting against the outer circumference of theinsulation dial 150 is shown. - In addition,
FIG. 6 shows theprotrusion 1255 a of thecrimper support 1255 fitted into thefitting section 142 formed in the outer circumference of thewire dial 140, with theupper edge 1254 a of thewire crimper 1254 abutting against thejaw 1255 b of thecrimper support 1255. - In the crimping
device 1, thetool ram 125 moves up and down in response to the press ram 11 (seeFIG. 3 ), which is movably provided in aspace 125 a above thetool ram 125, moving up and down. When thepress ram 11 moves down, the crimper or the like of thetool ram 125 suspended from thepress ram 11 comes into contact with the terminal placed under the crimper or the like, and thus, thepress ram 11 moving downward decelerates. Then, thepress ram 11 continues to move downward until it reaches a predetermined bottom dead center, and thus, thesurface 143 a of thewire dial 140 selected at that time is pressed downward. In this process, the terminal is crimped onto the stripped part of the wire. Thus, the crimp height for the coating of the wire and the crimp height for the core of the wire are adjusted by adjusting the bottom dead centers of theinsulation crimper 1253 and thewire crimper 1254, respectively, that are responsible for crimping. - The bottom dead center of the
insulation crimper 1253 for crimping of an insulation barrel n12 (seeFIG. 2 ) of the terminal is changed by rotating theinsulation dial 150, because the thickness of theinsulation dial 150 varies with the position along the circumference as described above. In this way, the crimp height for this part can be adjusted. - On the other hand, the bottom dead center of the
wire crimper 1254 for crimping of a wire barrel n13 (seeFIG. 2 ) of the terminal is changed by rotating thewire dial 140, because the cutting of thewire dial 140 varies with the position along the circumference as described above. In this way, the crimp height for this part can be adjusted. - As described above, in the crimping
device 1 according to this embodiment, the adjustment dials are disposed toward the operator, and therefore, the crimp height adjustment can be readily achieved. In addition, since the crimp height adjustment mechanism for a core and the crimp height adjustment mechanism for an insulating coating are disposed on the same axis, the height of the entire device can be reduced compared with conventional crimping devices with the adjustment dials disposed at different levels.
