Cl. 29-203 Claims ABSTRACT OF THE DISCLOSURE A contact removal tool for electrical connectors having a tubular plastic probe with a tangential slot to permit the tube walls to overlap as the probe is inserted in a restricted aperture and to thereafter resiliently expand to properly release an internal contact retention clip.
The present invention relates to an electrical connector tool.
The tool of the invention is for removing contacts from an electrical connector in which the contacts are held by resilient retainer clips in apertures only slightly larger than the contacts themselves. In the case of pin contacts, these are often used in closed entry apertures in the connector in which the outer terminal ends of the pins are adjacent the entry ends of the apertures and have larger base portions inwardly from the outer ends. The tool for use in removing the contacts must be contracted for insertion into the entry ends of the apertures and again enlarged after insertion into the apertures, for surrounding the larger portion of the pins. The removal tools heretofore used for this purpose have not been entirely satisfactory.
A broad object of the present invention is to provide a novel tool for removal of the contacts from an electrical connector in circumstances as set out above.
A more specific object is to provide a tool of the foregoing general character having a tubular removal probe for direct association with the contact and engagement with the retainer clips, which is provided with a novel tangential slot for enabling contraction of the probe for entry into the constricted portion of the aperture, and enlargement thereof to slip over the relatively large portion of the contacts and release the retainer clip.
A still more specific object is to provide a tool of the foregoing general character which is of plastic material and consequently of semi-rigid characteristics, having the desired axial rigidity but contractable circumferentially, and having a certain degree of yieldability so as to prevent injury to any of the elements of the connector.
Other objects and advantages of the invention will appear from the following detail description taken in conjunction with the accompanying drawings in which:
FIGURE 1 is an axial sectional view of the tool of the present invention;
FIGURE 2 is a perspective view of the removal probe portion of the tube;
FIGURE 3 is a sectional view taken at line 3-3 of FIGURE 1;
FIGURE 4 is a sectional view of an electrical connector of the character to which the tool of the present invention is particularly applicable;
FIGURE 5 is a sectional view of one part of the connector of FIGURE 4 and showing the tool in association therewith;
FIGURE 6 is a sectional view taken at line 66 of FIGURE 5;
FIGURE 7 is a view similar to FIGURE 5 but with the tool in a different position relative to the connector part; and
FIGURE 8 is a sectional view taken at line 8--8 of FIGURE 7.
Referring now in detail to the accompanying drawings attention is directed first to FIGURES 1, 2 and 3 showing the tool itself of the invention. The tool indicated in its entirety at 12 is generally tubular in shape and includes a central large or main portion 14, a contact insertion probe portion 16 which does not enter into the present invention, and a contact removal probe 18 which constitutes a principal feature of the invention. Forwardly of the main portion 14 is a reduced tubular portion 20 forwardly of which is a tapered section 22, and forwardly of the latter is a final section 24 constituting the probe proper. This section 24 is preferably of cylindrical shape and has a substantially thinner wall than the other portions. At its outer end is a slot 26 opening through the chamfered end surface 27 and extending tangentially of the inner diameter. This slot leads axially inwardly from the outer end to a cutout portion 28 which serves to substantially reduce the total amount of material at that portion to enable greater flexing effect. The cutout portion 28 extends the greater portion of the probe portion and is of substantially greater circumferential extent than the slot, forming a tab or lip 30 defining one side of the slot, while the other edge of the slot may lead directly into the corresponding edge of the cutout portion.
Ejection means indicated in its entirety at 32 may be provided if desired, although this feature does not enter into the present invention. Such means may include a plunger 34 within the tool secured to a knob 36 generally exterior of the tool and having connection with the plunger through a slot 38. The plunger is biased to a retracted position (FIGURE 1) by a compression spring 40 and upon moving the knob 36 forwardly (to the left, FIGURE 1) the plunger is slid through the tool and out the end for ejecting a contact from the interior of the tool.
The tool 12 is made of plastic material, preferably polypropylene, which provides the desired rigidity longitudinally or axially of the tool, but provides also the desired flexibility for contraction in circumferential direction as will be referred to again, in the removal of the contacts from the connector. Also the material of the tool itself possesses a certain degree of yieldability as compared to metal, thus eliminating injury to any of the elements of the connector in the removal of the contacts.
A connector of the type with which the tool is particularly useful is shown in FIGURES 4 and 5. It includes two main parts, namely a receptacle 42 and a plug 44 releaseably connected together by means of a coupling ring 46. The details of this coupling means are disclosed and claimed in the copending application of John Cameron Ser. No. 580,744 filed Sept. 20, 1966, now abandoned, assigned to the assignee of the present invention.
The receptacle 42 includes a hard dielectric insert 48 having a plurality of apertures 50 receiving pin contacts 52, each of which has a pin element 54 at its outer end, inwardly of which is a tapered surface 55 merging with a large diameter base element 56 defining an inwardly directed shoulder 58. The pin contact is releaseably held in the aperture by means of a snap-in contact retention clip 60 which itself is releaseably held in the aperture by engagement with an internal rib or bead 62 in the surface of the aperture and has fingers 64 with shoulders or end surfaces 66 engaging the shoulder 58, and terminal elements 68 extending axially beyond that shoulder and overlying the base element 56, these extensions having inclined camming surfaces 70 utilized for releasing the pin contact from the clip as described hereinbelow. The clip and hard dielectric insert are disclosed and claimed in the copending application of Joseph F. Chirumbulo 3 Ser. No. 581,903 filed Sept. 26, 1966 assigned to the assignee of the present invention.
The apertures 50 are of the closed entry type, the insert 48 having an inwardly projecting bead 72 at the entry, chamfered as at 73, barely larger than the base element 56, as will be referred to again hereinbelow. The plug 44 includes a hard dielectric insert 74 having apertures 76 for receiving socket contacts 78 each of which has a socket element 80 at its outer end and extending substantially outwardly beyond the end of the insert 74. The pin element 54 extends longitudinally no farther than the end of the insert 48, and preferably slightly inwardly therefrom, although within the axial extent of the bead 72. The socket element 80 has an outer diameter preferably substantially the same as the diameter of the base element 56 of the pin contact and has a socket 82 receiving the pin element 54 and dimensioned for friction and rubbing contact engagement therewith for establishing electrical contact engagement between the pin contact and socket contact. The socket element 80 has a shoulder 84 engaged by a contact retention clip 86 of the same construction as the clip 64. A socket insert face seal 88 is provided, preferably bonded to the insert 74 and engaging the other insert 48 when the connector is connected.
In the coupling operation the two parts 42, 44 are fitted together and the socket elements 80 of the plug enter into the apertures 50 of the receptacle a substantial extent, the chamfers 73 aiding in the insertion. Also the outer end of the socket element 80 and the end of the pin element 54 may be chamfered for this purpose, as illustrated.
To remove the pin contacts 52 the tool 12 is utilized as indicated in FIGURES 5 to 8. The closed entry of the socket 50 is pre-dimensioned to as small a diameter as possible for purposes of maintaining proper alignment between the pin 54 and the socket element 80. This poses difiiculties in removal of the pin contact, but in the use of the tool of the present invention the probe 24 of the tool is inserted into the aperture 50 around the pin element 54, and to accommodate the small diameter of the closed entry of the aperture, the probe is enabled to contract as shown in FIGURE 6 where the slot 26 is shown substantially closed (compare FIGURE 3). The tangential direction of the slot enables the probe to wrap up, or contract, so that the edges of the slot overlap in entering through the closed entry of the aperture, the slot 26 closing but the outer periphery of the probe remaining substantially circular in shape.
The tool is then moved further into the socket and upon engaging the tapered surface 55 spreads and moves onto the base element 56. This condition is shown in FIGURE 8 where the slot 26 is substantially larger than its normal dimension shown in FIGURE 3. Upon continued movement the chamfered edge 27 of the tool enters under the inclined surface 70 of the finger elements 68 and spreads the fingers so that the shoulders 66 ride out beyond the shoulder 58, enabling the pin contact to be removed.
The cutout portion 28 provides a wide range of contraction and expansion of the probe, and particularly the outer terminal end portion thereof. This portion, including the tab 30 must both contract in the closed entry end of the socket and expand on moving onto the large diameter element 56. The provision of the cutout portion 28 enhances this action, resulting in less body of the probe and correspondingly less rigidity or resistance, so that the end portion can easily contract in entering into the socket and later expand over the base element 56.
The probe is preferably dimensioned so as to directly engage or hug the base element 56 to assure minimum dimension of the probe when on that element, and to assure that the chamfered surface 27 enters under the inclined surfaces 70 of the ifinger elements 68.
The plastic material of which the tool is made possesses the necessary rigidity in longitudinal or axial direction necessary for spreading the finger elements of the clip but it also provides the desired flexibility in circumferential direction to enable and facilitate the contraction and expansion in circumferential direction of the probe portion of the tool. This contraction and expansion is accomplished without any injury to any of the elements of the connector, and additionally the inherent yieldability of the plastic material of the tool eliminates injury upon engagement with various elements of the connector and thus overcomes a serious disadvantage of tools of other types heretofore known.
The socket contact 78 may be removed in a manner similar to that described above. In connection with removing the socket contact, however the probe need not be contracted in entering into the aperture 76 because the latter is not of closed entry type and is of a diameter substantially larger than the outer diameter of the socket element 80. When the connector is disconnected, the seal 88, not being compressed, reassumes an expanded position in which the aperture therein is sufliciently large to readily admit the probe of the tool. Upon insertion of the tool sufiiciently to engage the clip 86, the clip is released in the manner described above, enabling removal of the socket contact 78.
While I have herein disclosed a preferred form of the invention it will be understood that changes may be made therein within the spirit and scope of the appended claims.
I claim:
1. A tool of the character disclosed comprising a body including a tubular end removal probe having a tangential slot therein opening through the end surface thereof enabling overlapping of the tube walls upon inward circumferential flexing of the probe and corresponding increase and decrease in its effective diameter.
2. The invention according to claim 1 wherein the probe element includes a chamfered terminal end portion extending entirely circumferentially except for said slot, and is provided with a cutout portion of substantial circumferential extent inwardly from the outer end of the probe element.
3. The invention according to claim 2 wherein said probe portion is of cylindrical shape, the cutout portion forms a tab at the terminal end of the probe portion of short axial extent, and the cutout portion extends the major extent of the probe portion.
4. The invention according to claim 1 wherein at least the probe portion of the tool is made of plastic material having substantial rigidity in axial direction, but providing substantial flexibility in circumferential directon at the region of said slot, and the plastic material provides a limited degree of yieldability upon engagement with other elements.
5. The invention according to claim 4 wherein the plastic material is polypropylene.
