7 Claims.
This invention relates to apparatus for severing and crimping electrical connectors. More particularly it has to do with apparatus for serially feeding a procession of similar electrical connectors into operative relationship with a pair of crimping dies and crimping the connectors onto the ends of electrical conductors.
Heretofore most electrical apparatus such as control systems, networks, radios, etc., have depended upon soldered connections, until comparatively recently, when crimped connections came into extensive use. In making these connections, the end of a conductor was inserted into a ferrule or other conductor-receiving element of the electrical connector and there soldered or crimped in place. For the most part these operations were performed by hand, although there have been attempts made at performing some of the operations semi-automatically. Thus, it is fairly common today to nd power-operated presses for carrying out routine crimping operations. Such prior equipment has not been wholly satisfactory, however, because of the'fact that the parts to be crimped and operated upon are all small and difficult to handle. Each connector had to be individually positioned upon the conductor and then the assembled connector and conductor had to be positioned within closely specied limits in operative relationship between the crimping dies before the press could be actuated.
It is an object of the present invention to provide means for feeding a series of connectors to a region of operation wherein each connector may be correctly crimped to the end of an electrical conductor. A further object is the provision of apparatus for performing a crimping operation Where relatively large numbers of crimped connectors are required and wherein the crimped connections must conform to exacting standards. Another object is the provision of means for feeding a strip-type of multiple connector wherein the crimping operation is combined with a shearing operation so as to complete the formation of a connector and simultaneously crimp it directly onto an electrical conductor. An additional object is the provision of apparatus for feeding and crimping strips of connectors wherein the strips fed into the machine are of a large enough size to be handled easily and from which lightweight electricalrconnectors may be individually sheared and crimped in a manner such as to avoid individual handling of the small connectors which are a part of the finished product. Other objects will be in part pointed out CII as the description proceeds and will in part become apparent therefrom.
In the application of William S. Watts, Serial No. 514,214, led December 14, 1943, there is disclosed and claimed a type of electrical connector wherein the connectors are formed in long strips, each individual connector (except the two end connectors) being integral with two other connectors, one on either side thereof. The present invention provides apparatus peculiarly well suited to feeding strip-type connectors such as disclosed and claimed lin said application, and for crimping the end connector of the strip directly onto the end of an electrical conductor. Means are provided for feeding the strip of connectors so as to place the end connector in a predetermined fashion between two dies so that in closing upon the connector the dies may at the same time sever the connector from the strip and crimp the connector onto the end of the conductor. In addition means are included for assuring that the end connector is properly positioned with each repeated cycle of the machine so that no time is lost in positioning the end of a conductor within the ferrule or conductor receiving portion of the connector.
In this specification and the accompanying drawing, I have shown and described a preferred embodiment of my invention and various modifications thereof; it is to be understood that these are not intended to be exhaustive nor limiting of the invention, but on the contrary are given for the purpose of illustration in order that others skilled in the art may fully understand the invention and the principles thereof and the manner of applying it in practical use so that they may modify and adapt it in various forms, each as may be best suited to the conditions of a particular use.
In the accompanying' drawing, in which only one form of the 'invention is specifically illustrated:
Figure 1 is a side elevation with parts broken away showing the machine with a strip of electrical connectors therein in position for operation of the machine to begin;
Figure 2 is a sectional view of part of the machine taken along the line 2-2 of Figure l in the direction of the arrows;
Figure 3 is a sectional view of part of the machine taken along the line 3'-3 of Figurev l in the direction of the arrows;
Figure 4 is a perspective view of one of the shearing dies of the machine illustrated in Figurea-:lf3:
Figure 5 is a perspective view oi an electrical connector crimped onto an electrical conductor by the apparatus illustrated in Figures l-A; and
Figure 6 is a sectional view taken along the line 6 6 of Figure 5 in the direction of the arrows.
In Figure l, a strip of connectors generally indicated by the numeral 2li is shown extending downwardly through the central portion of the apparatus to a position between a stationary crimping die 22 and a movable crimping die 2t. Die 24 is reciprocable toward and away from stationary die 22 by means of a die member 2b operated by a rocker arm and a connecting link 3u. Link t@ is actuated by a bell crank lever 32 connected to a push rod @il which in turn is movable through a pedal 35. Adjacent to stationary die 22 is a ferrule stop 38 (see also Figure 2) for positioning the end oi; the strip of connectors in the desired relationship with respect to the die. A stationary shearing die il@ is posi tioned above stationary die 22 and. stop 3b, and a movable shearing die i2 is rigidly :dried to mov able crimping die 2A in a manner so as to co= operate with die il@ to sever the end connector 2ila from the strip of connectors during a crimping operation.
Bell crank lever 32 is mounted upon a shaft it carried by a bracket extending from the trame of the machine. A sprocket wheel it is mounted upon shaft ift so as to be rotated counterclockwise with each downward operation of pedal A sprocket chain 'till extends from wheel fill up wardly and to the left, as viewed .in Figure l., to a second sprocket wheel 52. Wheel 52 is freely rotatable upon a countershaft 5G mounted in brackets upon the machine frame. A ratchet is positioned freely upon shaft beside sprocket wheel 52 (see also Figure 2). A driving pawl 5t is fixed upon sprocket wheel 5t in driving :ree lationship with ratchet :it so as to turn the ratchet counterclockwise with each downward operation of pedal 36. A locking pawl bil, mounted upon' the frame of the machine, engages ratchet 56 to prevent it from rotating clockwise upon the return of pedal it. One end of a draw spring `62 is attached to a. stud @d carried by ratchet 56. The other end of the draw spring is attached to countershait 54. The arrangement is such that each time ratchet il@ turns countenclockwise it tends to wind the end of draw spring t2 in a counterclockwise direction around coun tershaft 5i (since countershaft 5t is not free to rotate until later in the cycle, as will be described hereinafter). Countershaft 5t is provided with a stop 66 (see also Figure 2) which prevents countershaft 54 from ever turning counterclockwise with respect to ratchet 56 more than a predetermined amount.
A feed wheel 68 is keyed to countershaft 5ft and is provided around its outer periphery with a series of sprockets lll. These sprockets are spaced so as to cooperate with openings in the ferrules and hence feed them downwardly each time feed wheel 68 turns in a counterclockwise direction. In the connector illustrated (see Figure 5) the openings which cooperate with sprockets 'ill serve also to receive a binding post when an electrical contact is to be made by the connector.
The frame of the machine carries a detent 'l2 positioned below feed wheel to so as to engage with seats 'M located around the exterior of the feed wheel adjacent sprockets llt. These seats are related to the spacing of the electrical connectors so that the detent will engage in a seat with a slight camming action at the end or a aseaeie feeding operation and hence ald in positioning the strip of electrical connectors and so that the end connector 20a is correctly located With respect to stationary die 22 and against stop 38. Stop 33 prevents wheel t8 from overfeeding, and detent l2 and stops 'M aid draw spring 62 in assuring that the strip of connectors is not permitted to back away slightly from stop 37o?.
In operation, a strip of electrical connectors is fed to the machine and the end connector 20a is nicely positioned against stop tt. One of the sprockets 'l0 is in alignment with the opening in one of the electrical connectors so that when rotation of feed wheel 63 is permitted, the strip of connectors will be fed downwardly to position another connector in the correct relationship between the dies. When pedal 36 is pressed downwardly by the operator, or when it is operated automatically, as by a pneumatic cylinder, for example, the motion is transmitted through the linkages described and die member 2t is forced to the right, as illustrated in Figure l, so that shearing die d2 cooperates with shearing die til (see also Figure A) lto punch out a piece 2Gb and sever connector 2da from the strip, and movable crimping die 2A closes upon connector 2da to crimp its ferrule onto the end of an electrical conductor, such as the conductor 2l illustrated in Figure 5. As soon as the end connector is re moved, countershait 5d and feed wheel d8 are free to move under the iniiuence of draw spring t2 to position the next connector in operative crimping relationship. Draw spring tit is loaded through the pawl and ratchet arrangement each time pedal 36 is moved downwardly and has suf iicient strength, when loaded, to unseat detent 'i2 from its stop lil.
The crimp itself may be of any desired type and preferably is of the type disclosed and claimed in the co-pending application of U. A. Whitaker, Serial No. 455,039, filed August i7, 1942. Other forms of connector may be used with equal success. The electrical conductors may be positioned within the connector ierrules either manually or automatically.
As various embodiments may be made of the above invention and as changes might be made in the embodiment above set forth, it is to be understood that all matter hereinbefore set forth or shown in the accompanying drawing is to be interpreted as illustrative and not in a limiting sense.
