Definitions
- Another common locking device is a pin and camming surface whereby the stationary connector has one or more pins located on its outer shell, and the cable connector has a slot in its shell to match each pin of the stationary connector.
- the cable connector shell is twisted so that the pin moves along the slot in a camming action to draw the two connectors securely together.
- a groove At the end of the slot is located a groove whereby the pin may seat to lock the two connectors in a mating position.
- the pin maynot be securely seated in the groove.
- the cable connector shell may twist slightly from vibration or cable movement causing the pin to no longer be located over the groove. Therefore, if a sudden pull or jerk was accidentally exerted on the cable, the two connectors may pull apart.
- the present invention represents a new locking device over the previous locking mechanisms shown. It has ease of operation, simplicity of design, and high reliability not present in the prior art.
- It is a still further object of this invention provide a connector assembly locking mechanism whereby a ridge of a locking sleeve of the cable connector is pressed into an undercut groove of the housing of the stationary connector to provide a retaining force when the two connectors are mated together; but after being mated, if a pull is exerted on the cable, a wedge surface of the cable connector will provide an outward force on the locking sleeve to securely lock the ridge in the groove so that the connectors can only be disconnected by physically gripping the sleeve and sliding it along the connector assembly to remove the wedging action and retaining force.
- FIG. 1 is a longitudinal sectional view of a cable connector assembly with a cable connected thereto.
- FIG. 2 is a partially exploded view of the structure shown in FIG. 1.
- FIG. 3 is a partial sectional view of the structure of FIG. 1, showing the parts enlarged to better illustrate the invention.
- FIG. 1 a sectional view of two connectors mated together with the stationary connector being designated generally by reference numeral and the cable connector being designated generally by reference numeral 12.
- the stationary connector consists generally of a housing 14 for containing the male connector pin 18 which is surrounded by insulation 16.
- a guide 20 helps position the cable connector 12 so that it will be easier to assemble the two connectors 10 and 12.
- the cable connector consists generally of a female contact 22 surrounded by insulation 24 contained within The body 26.
- the center part of the body 26 is encircled by a freely rotating locking'sleeve 28.
- a retaining nut 30 pulls the cable nut 32 against the clamp 34 to hold the cable 36 in rigid position.
- the clamp 34 is separated from the contact 22 by an insulating washer 38.
- the cable 36 is prepared for the connector 12 by removing a portion 10f the covering 40 and shield 42, and a smaller portion of the insulation 44 whereby the wire 46 can be inserted into the connector contact 22 with the insulation 44 abutting the contact 22 and the covering 40 and shield 42 being forced against the clamp 34.
- To assemble the connector first put the cable nut 32 on the cable 36 and then slide the clamp 34 under covering '40 and shield 44. Put the insulating washer 38 over the cableinsulation 44 and against the clamp 34 before inserting the wire 46 in the contact 22.
- solder is applied through an opening 48 to the cavity SOIinto which the wire 46 was inserted.
- Contact 22 is then inserted into the body assembly 51 (shown in FIG.
- the body 26 and insulation 24 are joined together by inserting the insulation 24 into the body 26 and crimping them togetherat the slotted portion 62 of the body.
- the locking sleeve 28, is slid over the body 26 and the retaining nut 30 is butted against the shoulders 64 of the body 26 in the position as showns
- the end of the body 26 inside the retaining nut is bent outward to form a flange 60 which holds the body assembly 51' together.
- the stationary connector 10 is, for the most part, a standard plug receptacle.
- the pin 18 is embedded in the insulation 16 with point 66 electrically mating the spring pins 68 of contact 22.
- the lead portions 70 and 72 of point 66 and spring pins 68, respectively, are conically shaped to provide an easier mating connection.
- the insulator 16 has a forward cylinder portion 74 to protect the point 66 and ensure the necessary electrical insulation. Shoulder 76 of the insulation 16 butts shoulder 78 of the guide 20 with the flange 80 of the housing holding the connector 10 together.
- the guide 20 is physically attached to the housing 14 by some type of bonding.
- the forward portion 82 of the guide 20 is arcuate to conform to beveled rim 84 of the extension 86 by body 26.
- the arcuate shape 82 and beveled rim 84 provide an easy mating of the two connectors 10 and 12.
- the housing 14 is screwed into a chassis or bolted to a chassis by means of threads 88 with the flange 90 pressing against the panel surface.
- the locking sleeve 28 has tines 92 extending toward the left of connector 12.
- Each of the tines 92 have outwardly extending ridges 94 with two oppositely beveled surfaces 96 and 98.
- the inside left portion 93 of the tine 92 is arcuate.
- the housing 14 of connector 10 has undercut 100 into which the ridge 94 of the tines 92 will seat.
- the undercut 100 is beveled so that surface 102 matches the correspondingly beveled surface 96 in the ridge-94.
- Beveled surface 98 of the ridge 94 facilitates assembly of the cable connector 12 to the stationary connector 10. It is not necessary that beveled surface 98 of the ridge 94 have a corresponding cut as does beveled surface 104 in the housing 14.
- the locking of the two connectors and 12 occurs in the following manner.
- the tines 92 are forced inwardly by beveled surface 98 sliding along the beveled surface 106. Once the ridge 94 reaches the undercut 100, the tines 92 spring outwardly. The outward force of the tines 92 securely seats the ridge 94 in the undercut 100. Thereafter, if a pull or jerk is exerted on the cable 36, the beveled surface 96 of the ridge 94 will press against the beveled surface 102 of the housing 14.
- the force of the pull on the locking sleeve 28 will slide the arcuate portion 93 along the wedging surface 108 thereby moving the connector 12 slightly to the left which allows the locking sleeve 28 to move to the right and depress the tines 92 inside the housing 14.
- the connectors 10 and 12 are free to separate. Upon separation, the tines 92 spring outward into their normal position.
- said tines being forced inwardly by a leading slope on said tines and ridge when said first and second connectors are pushed together;
- said undercut and ridge being matchingly sloped on the rearward edge of said ridge os that when said ridge is seated in said undercut the two matchingly sloped surfaces are flat against one another; said matching slope causing interference which forces said sleeve to slide along said second connector when force is applied to separate the two connectors unless said ridge has first been unseated by a ull on said sleeve; said wedging surface avrng a lessor angle with respect to the longitudinal axis of said connectors than the angle of said matching slopes, the sleeve moving along said second connector until said tines contact said wedging surface upon attempted separation other than pulling on said slidable sleeve thereby forcing said ridge to remain seated in said undercut and stopping the separation of the connectors;
- the mating end of said body being of greater diameter than said sleeve
- the cable end of said body having an extension that is bent outwardly to form a flange which secures a retaining nut, said retaining nut holding said cable clamp to said second connection, said retaining nut providing a stop for said slidable sleeve.
