Figs. 1A to 1F are sectional views for fitting steps for a pair of connector housings in preferred embodiment of the present invention.
Figs. 32A to 32E are illustrative views for showing processes in which the lock confirming slider is assembled to the connector housing.
To the terminal accommodating cavities 12 are inserted small-sized sensor circuit terminals F' connected to the wires (w) in advance. Engaging pieces F₁' is engaged with an upper opening 12a so as to prevent its removal and then the terminal F' is exposed at an inner opening 12b.
A substantial V-shaped short circuiting resilient contact element G' is arranged by fitting its base end to a substantial V-shaped supporting groove 7a formed at the base portion 7 of the lock confirming slider E', and its contact end G₁' can be contacted with the sensor circuit terminal F' through the opening 12b.
With such an arrangement above, when a complete fitting with a mating connector is attained, the lock confirming slider E' released a restriction with the lock arm 5 automatically advances with a tension force of the coil springs 14, a contact end G₁' of the short circuiting resilient contact element G' is contacted with sensor circuit terminals F' through an opening 12a so as to close a sensor circuit.
Between a pair of rails 110 of the male connector housing A', two fixing winding portions G₂ formed at corners of about U-shaped short circuiting automatic lock confirming resilient piece G are engaged with fixing levers 113. Base portion G₁ is engaged with a biasing projection 114, thereby both resilient contact portions G₃ are arranged so as to be contactable with the sensor circuit terminals F through the openings 112b. There are provided driven portions G₄ continuous with the resilient contact portions G₃ and bent inwardly. End surfaces of the fixing levers 113 and the biasing projection 114 are formed as tapered surfaces 113a and 114a. Under a condition in which the lock confirming slider E' is installed in the male connector housing A', the short circuiting automatic lock confirming resilient piece G is pushed into a clearance S at the rear part to cause the fixing windings G₂ and the base portion G₁ to be engaged with the fixing levers 113 and the biasing projection 114 through the tapered surfaces 113a and 114a. (Fig. 11).
In front of the base portion 107 of the lock confirming slider E' is formed a curved driving surface 115 in opposition to the driven portions G₄ of the short circuiting automatic lock confirming resilient piece G. A pair of driven portions G₄ and G₄ are abutted against the curved driving surface 115 while being displaced vertically.
At first as shown in Fig. 10A, the lock confirming slider E' is operated such that a lock arm 105 is pushed down by a jig to release the engagement with the lock sensor arm 108 and the short circuiting automatic lock confirming resilient piece G is installed in the male connector housing A' while it is moved forward, and under this condition the lock confirming slider E' is retracted (Fig. 10B). At this time the curved driving surface 115 causes the short circuiting automatic lock confirming resilient piece G to be displaced inwardly through the driven portions G₄ against their resiliencies. The abutting part 108a of the lock sensor arm 108 is engaged with the engaging part 105c of the lock arm 105 through its further retracting movement and is fixed at its preset state. Under this state, both resilient contact portions G₃ of the short circuiting automatic lock confirming resilient piece G are bent inwardly against their resiliencies. (Fig. 10C).
With such an arrangement as above, the lock confirming slider E' released from its restriction with the lock arm 105 under a complete fitting with its mating connector is moved forward automatically by resilient forces of the bent resilient contact portions G₃ (see Fig. 10C) and at the same time the resilient contact pieces G₃ are contacted with the sensor circuit terminals F to close the sensor circuit. (Fig. 10A).
In case of the preferred embodiment shown in Figs. 12 and 13, a forward curved driving surface 115' is formed at a rear end between a pair of rails 110 of the male connector housing A''. A short circuiting automatic lock confirming resilient piece G' is fixed to the base portion 107 of the lock confirming slider E''.
The short circuiting automatic lock confirming resilient piece G' has contact portions G₂' wound around bent portions between a base portion G₁' and each of a pair of resilient displacement portions G₃', has driven portions G₄' bent inwardly at its free ends, in which the base portion G₁' is supported by the engaging portions 116 to cause the driven portions G₄' to be oppositely facing against the curved driving surface 115' at the male connector housing A''.
With such an arrangement, as shown in Fig. 13, the lock confirming slider E'' assembled with the short circuiting automatic lock confirming resilient piece G' is assembled with the male connector housing A'' at its rear part and moved forward, thereby the driven portions G₄' are engaged with the curved driving surface 115' (Fig. 14A), and then pulled down until the lock sensor arm 108 is engaged with the lock arm and preset (Fig. 14C).
Under the preset condition, the lock confirming slider E'' is already retracted, so that the resilient displacement portions G₃' is bent inwardly by the curved driving portion 115'. When the male connector housing A'' is completely fitted with its mating connector housing, the lock confirming slider E'' starts to advance due to the resilient displacement portions G₃' (Fig. 14B) and the contact portions G₂' are contacted with the sensor circuit terminals F at the most-forward position to close the sensor circuit (Fig. 14A).
In the preferred embodiment shown in Figs. 15 to 17, a pair of supporting frames 110' are extended rearwardly from the rear part of a male connector housing A''', sliding frames 111' formed at both sides of the lock confirming slider E''' are engaged in the grooves 110''' formed by the supporting frames 110'. A pair of supporting frames 110' are formed with terminal accommodating cavities 112 opened rearwardly, respectively.
Into the terminal accommodating cavities 112 are inserted and engaged the small-sized sensor circuit terminals F connected in advance with an electrical wire in the same manner as that of the aforesaid preferred embodiment and they are exposed at the lower openings 112c adjacent to the grooves 110''.
To a rear part of a base portion 7 of the lock confirming slider E''' is cooperatively arranged a pusher operating part 107', and the short circuiting automatic lock confirming resilient pieces G'' are arranged over between the sliding frames 111' set at both lower sides. The short circuiting automatic lock confirming resilient pieces G'' has biasing wound portions G₂'' on a U-shaped base portion G₁'', has resilient displacement portions G₃'' directed downwardly from the biasing wound portions G₂'' and has resilient contact portions G₅'' bent forwardly at each of the resilient displacement portions G₃'', G₃'' through supporting shaft portions G₄'', G₄'' bent outwardly.
The sliding frames 111'' are formed with supporting grooves 111a' in a direction crossing with a moving direction of the lock confirming slider E''', and outside portions thereof are provided with storing concave portions 111b' opened upwardly in continuous with the supporting grooves 111a'.
As shown in Fig. 15, the short circuiting automatic lock confirming resilient piece G'' is operated such that each of the supporting shaft portions G₄'' is assembled with the lock confirming slider E''' while each of the supporting shaft portions G₄'' is engaged with the supporting grooves 111a' of the sliding frames 111' and the resilient contact portions G₅'' are positioned within the storing concave portions 111b'. In this case, each of the biasing wound portions G₂'' is positioned at a side part of the pusher operating part 107' and the U-shaped base portion G₁'' is positioned below the pusher operating part 107'.
The lock confirming slider E''' assembled with the short circuiting lock confirming resilient pieces G'' cause at first both sliding frames 111' to be inserted at the rear part of the male connector housing A''' into the grooves 110'' and further cause the U-shaped base portion G₁'' to be engaged with a biasing projection 114' raised at a rear end between the groves 110'' and 110'' of the male connector housing A''', and under this state, the resilient contact portions G₅'' are contacted with the sensor circuit terminals F from the openings 112c (Figs. 16A and 16B).
Then, as indicated in the prior art, the lock confirming slider E''' is pulled down until the abutting part 108a of the lock sensing arm 108 is engaged with the lock arm, and then it is preset (Figs. 17A and 17B). Under this condition, the U-shaped base portion G₁'' of the short circuiting automatic lock confirming resilient piece G'' approaches resilient displacement portions G₃'' and a strong resilient force is accumulated in the biasing wound portions G₂''.
With such an arrangement as above, when the male connector housing A''' is completely fitted to its mating connector housing, the lock confirming slider E''' is moved forward under a biasing action of the resilient displacement part G₃'' or the like and the resilient contact part G₅'' is contacted with the sensor circuit terminal F to close the sensor circuit (see Fig. 16).
Small-sized sensor circuit terminals F connected to electrical wires W in advance are inserted into the terminal accommodating cavities 212 to cause the engaging pieces F₁ to be engaged with the upper openings 212a and the terminals F are exposed at the inner openings 212b.
At the rear surface 207b, the short circuiting automatic lock confirming resilient piece G is attached through a fixing lever 214. The short circuiting automatic lock confirming resilient piece G has an engaging piece G₃ formed with a fixed contact part G₂ projected through its bending at one side of the fixing wound part G₁, has at the other side has a resilient piece G₅ provided with a movable contact part G₄ at its extreme end. The engaging piece G₃ is engaged with a projection 215 under a fixing condition in which the fixing wound portion G₁ is engaged with the fixing lever 214 and at the same time the resilient piece G₅ is engaged with the sliding guide lever 208d of the lock sensor arm 208', resulting in that the lock sensor arm 208' is always biased forwardly by the resilient piece G₅.
With such an arrangement as above, although the fixed contact part G₂ is always contacted with one sensor circuit terminal F through the opening 212b, the lock sensor arm 208' is retracted under a non-fitted state, so that the resilient piece G₅ is displaced rearwardly and the movable contact part G₄ is in a non-contacted state with the other sensor circuit terminal F (Fig. 24A). When the male connector housing A is completely fitted to its mating connector housing, the lock sensor arm 208' is moved forward by the resilient piece G₅, the movable contact part G₄ is contacted with the other sensor circuit terminal F so close the sensor circuit (Fig. 24B).
Figs. 22 to 32 illustrate another preferred embodiment of the present invention. As shown in Fig. 22, it is comprised of a male connector housing A", a lock confirming slider E'' having a lock sensor arm 208, a short circuiting automatic lock confirming resilient piece G' and a biasing operating element H.
In the male connector housing A'', a pair of supporting frames 210' are extended rearwardly from a rear part of a jacket 209 to form a storing space R. Each of the supporting frames 210' is formed with a groove 210a' directed toward the storing space R and with a terminal storing chamber 212 opened rearwardly.
Both sides of the base portion 207 of the lock confirming slider E'' are formed with the sliding portions 218 engaged with the grooves 210a'. A fixing lever 220 is vertically arranged within a concave part 219 at a rear part of a rear surface. At both sides of the concave part 219 are projected restricting walls 221 and 221 expanding forwardly in tapered form, and at the opposing sides a pair of supporting frames 222 and 222 having supporting grooves 222a are vertically arranged.
The short circuiting automatic lock confirming resilient piece G' has resilient displacing portions G₂', G₂' expanded in V-shape in respect to the fixing wound part G₁' and it has at a free end of each of the resilient displacement part G₂' a movable contact portion G₃' and a rised driven part G₄'.
The biasing operating element H has engaging portions 223 and 224 for a pair of supporting frames 222 of the lock confirming slider E'', has forked restricting portions 225 and 225 at its forward side and has a V-shaped driving surface 226 at an inner surface over a pair of restricting portions 225 and 225. A rear side surface of the restricting portion 225 is formed with an engaging concave part 227.
With such an arrangement above, in order to assemble these elements, the short circuiting automatic lock confirming resilient piece G' is assembled against the lock confirming slider E'' (Fig. 26 and Fig. 28B). Under this state, the fixing wound part G₁' is engaged with the fixing lever 220 within the concave part 219 and the resilient displacement portions G₂' and G₂' are forcedly contacted with the tapered restricting walls 221 and 221.
Then, the biasing operating element H is assembled with the lock confirming slider E'' while the engaging portions 223 and 224 are being engaged with the supporting frame 222 and its groove 222a. Under this state, the resilient displacing part G₂' of the short circuiting automatic confirming resilient piece G' is positioned below the restricting part 225 of the biasing operating element C and a movable contact portion G₃' at its free end is projected outwardly from a free end 225a of the restricting part 225 and at the same time the driven part G₄' is raised inside the free end 225 (Fig. 27, Fig. 28C).
As described above, the lock confirming slider E'' having the short circuiting automatic lock confirming resilient piece G' and the biasing operating element H is coupled at its rear part to the male connector housing A'', wherein it is pushed into the storing space while a pair of sliding portions 218 are being engaged with grooves 210a' of a pair of supporting frames 210' (Fig. 32B) and the lock sensor arm 208 is engaged with the lock arm 205 through its advancing movement, resulting in that the lock confirming slider E'' may not be moved forward more and at this state, only the biasing operating element H is started to be pushed (Fig. 32C). Upon completion of the pushing operation, the biasing operating element H is fixed by the engaging projections 210c' and 210d' (Figs. 29 and 30). Under this state, the resilient displacement part G₂' is forcedly displaced inwardly through the driven part G₄', resulting in getting a preset state accumulating a resilient force (Fig. 32D).
Under the preset condition, as the male connector housing A'' is fitted to its mating female connector housing, as shown in Fig. 1, the lock sensor arm 208 releases its restriction with the lock arm 205, the lock confirming slider E'' is moved forward through an operation of the resilient displacing part G₂' in its expanding direction, each of the movable contact portions G₃' of the short circuiting automatic lock confirming resilient piece G' is contacted with a pair of sensor circuit terminals F to operate the sensor circuit (Fig. 31, Fig. 32E).
