' 4 claims. (cl. 17e-269) 'I'his invention relates to electrical connecter umts for theft protective and other devices of automotive vehicles, and it is one of the objects of this invention to provide an electrical connecter that will operate to maintain an electrical connection with an armored terminal of a piece of electrical apparatus.

It is a further object o f the invention `to provide a yielding contact member of a terminal connecter whereby electrical connection will be completed and maintained throughout all stages o( connecter engagement.

-A further object of this invention is to contact elements in connecter units.

Further objects and advantages of the present invention will be apparent from the following description, reference being had to the accompanying drawing wherein a preferred embodiment of one form of the presentinvention is clearly shown.

In the drawing: Fig. 1 is a view,

improve partly 1u plan anaparuyln 2'5 tion with a piece of electrical apparatus. Fig. 2 is an enlarged longitudinal section illus-. tratlng the parts in position of rest or lion-con necting engagement, the view being substantially that indicated by the line and arrows 2 2 of Fig. 3 is an end elevation of the connecter unit embodying my invention substantially as'indicated by the arrow 3 of Fig. 2. A

Fig. 4 is an enlarged sectional view similar to Fig. 2. but illustrating the parts in cooperative relation with respect to the electrical apparatus with which it is connected.

With particular reference to the drawing, 20 refers to a cup of a piece of electrical apparatus,v

as a timer to which a control unit 50 has a self locking connection and electrical engagement', as illustrated particularly in Figs. l Aand. 4. The electrical apparatus 20 may be any preferred element of structure having a terminal stud 21 enclosed in an armored sleeve 22, and insulated from both the cup and sleeve by reason ofthe di' electric members 23 and 24. The terminal 21 is in ele'ctrical engagement with a circuit breaker lever 25 within the cup 20 through the agency of locking and connecting means 28 and 27 tively.

The circuit breaker mechanism 25 is ofthe conventional form used in ignition equipment, and includes a breaker plate 28 to the cup 20 at 29. A contact bracket 301s carried bythe improvement as applied to arself locking connes-A plate and has a contact 31 for engagement with contact 32 supported by circuit' breaker lever 25. The circuit breaker lever 25 is in insulated relation with respect to the bracket 30th'rough the agency of a dielectric bushing33 about a pivot 60 34,-and .is in electrical communication with the terminal stud 2l, through the agency of the conductor 27 which operates also a circuit breaker spring urging the same into following engagement with a timer cam 35 at the axisof the timer 65 cup 20. l i

The terminal stud 21 being insulated with respect to the housing 20 thereby provides an exterior terminalof the'circuit breaker mechanism, and is adapted to make electrical and mechanlcal engagement with an armored conducter or controller 50 hereinbefore referred to. For this f purpose the stud 2l terminates in va conical contact head 4 0 with a reduced neck 4l'. and is insulated relative to thefenclosingshell 22 with 75 Vwhich it ls surrounded, ibyau insulated washer l '-42 as illustrated in Figs. 1 and 4. Also connected longitudinal section, illustrating the use of with the stud 21 is a terminal 43 attached to a A'lead 44301 a condenser 45 mechanically and' electrically connected with the housing 20 by a clip 80 4.6

-he connecter unit 5l) vhereinbefore referred to includes armored cable 51 secured at one end -wltiun a protective shell 5 2 that has'mutmg engagement with the protective shell 22 earlier de- 85 scribed. Within the armored Acable 51 a flexible metallic loom 53 enclosing an insulated conductor 54, and a stress wire 55 is secured so as to .provide additional protection against unauthorized access to the enclosed conductor, and manipulation of the parts thereby protected. Within the protective shell 52 and disposed against one end of the armor 51 is a dielectric sleeve 56 that is of stepped bore, forming the axially aligned passages 57, 58 and 59. The enlarged portion 58 95 will be designated as a contact chamber.

The conductor 54 terminates. within the contact. chamber 58 in a bared end 60 to whlchis secured a contact cup 61 as by'soldering'at 62. The cup 61 has its rim ilanedoutwardly to' provide 100 a ange 63 of substantially the same diameter as the contact chamber v58, yet sufllciently smaller so as to allow'the'same to move freely axially of the central bore of the sleeve 56.- This construction provides an annular recess, so to speak. about the end of the conductor and contact 'cup 61 within the chamber 58, and within this annularrecessisdisposedacontacturgingspringi that is disposed against the bottom of the bore 58 and against the flange 63 of the cup. The ll0 spring normally tends to urge the cup and its attached conductor 54 along the axis of the sleeve 56 towaiz'd the enlarged opening 59 as illustrated in Fig. A

Within the largest of the bores of the sleeve 56, that is within the bore 59, there is dispom a spring locking device comprising the locking washer 70 and its backing washer 7l as clearly .illustrated in the drawing. For retaining the locking device within the sleeve there is provided a dielectric washer 'I2 disposed against the end of the sleeve 56`within the end of the shell 52 and the washer 72 is retained therein by a spanner nut 73 threaded within the end of the shell 52.

Fig. 2 illustrates the position of the parts before the coupling unit is attached to the electrical apparatus, and here it will be seen that the contact cup 6l is urged to the right hand end of the chamber 58 by the spring 64, and that the locking device is in its original form. Here too, is illustrated in dotted lines the contact head 40 o! the terminal stud 41, presented ready for mating engagement with -the locking device and with the contact cup.

It is obvious that when`the coupling unit is presented within the shell 22 andcausedto mate therewith so that the contact head 40 is received by and locked with the spring lock washer 70, that the union ot parts will be 'that illustrated in Eig. 4, wherein the contact head 40 has passed through the locking device so that the locking tongues thereof will have sprung into engagement with the neck 4l, and so that the contact head left hand end oi the contact chamber 58 as il- K lustrated. A secure mechanical and electrical connection is thereby made between the electrical device and the coupling unit, whereby the coupling unit is restrained from withdrawal from the electrical apparatus by reason of the locking device engaging the neck 41 of the insulated terminal stud, and whereby the contact cup 6l, andV hence the insulated conductor 54, are maintained in electrical engagement with the contact head 40 throughout all conditions `otf the locking engagement of the coupling unit with th`e electrical a movable cup-shaped contact connected to said conductor wire therein: a lock washer having integral inwardly pointing resilient tongues and mounted within said socket; a terminal stud hav,- ing a groove with shoulders, and inserted through said washer and contacting with said cup to torm electrical contact with said conductor wire, the resilient tongues ot said washer engaging the shoulders oi' the groove of said terminal stud to prevent withdrawal ot the stud from the socket.

2. A circuit connecter, comprising in combination; a terminal member having a socket and supporting one end o! a conductor wire, said socket having-a yieldable contact connected to the conductor wire therein; a washer having integral resilient tongues and secured within the socket; and a terminal stud provided with a head portion to form shoulders which when inserted through said washer contacts with the yieldable contact to form an electrical connection with the conductor wire, the tongues ci the washer engaging the shoulders provided-by the head to prevent withdrawal of the stud from the socket.

3. A circuit connecter, comprising in combination; a terminal member having a socket and supporting one end of a conductor wire, said socket havingfa movable cup-shaped member connected to said conductor wire and a coil spring surrounding said conductor wire therein, said spring urging said cup-member in one direction; a lock washer having integral inwardly pointing lingers and secured within said socket to limit the movement o't said cup member within said socket; a terminal stud having a groove with shoulders, and inserted through said washer and engaging said cup-member to form an electrical connection with said conductor wire, the coiled spring urging the cup against the stud and the resilient tongues oi said washer engaging the shoulders oi' the groove of the stud to prevent withdrawal of said stud from the socket. 4. A circuit connecter, comprising in combination; a supporting member having a socket and supporting one end of a conductor wire, said socket having a yieldable contact connected to the conductor wire therein; a washer having resilient ilngers mounted in said socket; a terminal stud adapted to be connected with the conductor and having a tapered portion and an annular groove above the tapered portion, and inserted through said washer so that the tapered portion engages the yieldable contact to electrically connect the stud with the wire. and the resilient fingers of the washers engagingr the shoulders of the groove of the stud to prevent the-removal of said stud from said socket.
