DETAILED DESCRIPTION OF THE INVENTION
Reference will now be made in detail to the preferred embodiment of the present invention. Referring to FIG. 1 and FIG. 2, a connector assembly 100 in accordance with the present invention, which is mounted to a panel 8 to form a floating panel mount system 200, comprises an insulative housing 1, a plurality of conductive contacts 2 assembled to the housing 1, two spacers 3 assembled to the housing 1, a printed circuit board 4, a plurality of cables 5 electrically connected with the conductive contacts 2, a fixing pusher 6 attached to the housing 1 and a cover 6 assembled to the insulative housing 1.
The insulative housing 1 is substantially elongated and comprises a mating portion 10 forwardly extending and an arm/pier portion 12 rearwardly extending from one rear end of the mating portion 10. The housing 1 comprises a mating face 13 at a front end of the mating portion 10 and a terminating face 14 opposite to the mating face 13. The housing 1 also defines a front-to-back direction parallel to a mating direction of the connector assembly 100 and a longitudinal direction generally perpendicular to the front-to-back direction. The mating portion 10 comprises an upper wall 101, an opposite lower wall 102 and a partition wall 103 extending between the upper wall 101 and the lower wall 102 in the mating direction and thus, defining two L-shaped receiving spaces 104. The lower wall 102 defines a plurality of first passages 105 and a plurality of second passages 106 extending through the terminating face 14. A pair of first keys 107 and a pair of second keys 108 are respectively provided on outer surfaces of the upper wall 101 and the lower wall 102, and a distance between the pair of the first keys 107 is larger than that of the second keys 108 for polarization. A pair of guiding projections 109 outwardly extend from opposite side surfaces (not labeled) of the mating portion 10 for guiding a proper insertion of a complementary connector (not shown). The housing 1 further comprises a pair of supporting brackets 15 rearwardly extending from the terminating face 14 and bracketing rear openings (not labeled) of the second passages 106 therein.
The arm portion 12 of the housing 1 is composed of a flat plate 120 essentially connecting with the mating portion 10 and a leading portion 121 extending outwardly from the flat plate 120. The flat plate 120 defines a plurality of slots 1201 in an inner surface thereof for reliably securing to the cover 7 during overmolding the cover 7 with housing 1. The leading portion 121 comprises a pair of first protrusions 123 on opposite top and bottom surfaces thereof and a second protrusion 124 on most outer side surface thereof, and each protrusion 123, 124 defines a rearwardly inclined rear face 125. The pair of first protrusions 123 locates near a rear end of the leading portion 121. The second protrusion 124 locates near a front end of the leading portion 121.
The plural contacts 2 are divided into a first set 21 and a second set 22. The first set 21 is composed of seven contacts 2 used for transmitting signal. the second set 22 is composed of fifteen contacts 2 used for transmitting power. Each conductive contact 2 comprises a retention section 202, a mating section 201 extending from one end of the retention section 202 with a curved mating end 200 formed at a forward end thereof, and a tail section 203 extending from the other end of the retention section 202. Each spacer 3 is elongated and is made of insulative material. A plurality of through-holes 30 are defined through the spacers 3 corresponding to the first and second passages 105, 106.
The printed circuit board 4 has a plurality of soldering pads 40 on one edge thereof corresponding to the contacts 2 of the second set 22. A plurality of apertures 41 are defined near the other edge of the printed circuit board 4. In the preferred embodiment, the cable 5 comprises a first cable 51 having a plurality of first conductors 510 and a plurality of second cables 52. Each second cable 52 comprises a second conductor 520 in the center thereof.
Referring to FIGS. 1–2 and in conjunction with FIGS. 3–7, the fixing pusher 6 is formed with a box-shaped main body 60 and a pair of filling bars 61 forwardly extending from a front end of the main body 60. The main body 60 defines a T-shaped receiving opening 601 opened to one side near the housing 1 for moveable receiving the T-shaped leading portion 121 of the housing 1 (FIG. 4). The main body 60 further provides a pair of first stopping projections 604 on each rear inner surface thereof for respectively engaging with the first protrusions 123 and a second stopping projection 605 on forward side surface thereof. Each stopping projection 604, 605 defines an inclined front face 606 (FIG. 7).
The panel 8 is a rectangular board and defines a mounting opening 80 in a center thereof, and a pair of first and second fitting openings 81, 82 in communication with the mounting opening 81. The first and second fitting openings 81, 82 are respectively in alignment with the first and second keys 107, 108 of the housing 1 in the front-to-back direction.
Referring to FIGS. 1–2 in conjunction with FIGS. 3–7, in assembly, the contacts 2 of the first set 21 and the second set 22 are respectively inserted into the first passages 104 and the second passages 105 with the curved mating ends 200 of the mating sections 201 exposed into the receiving space 104. The retention sections 202 interferentially fit into corresponding passages 104, 105 for securing the conductive contacts 2 to the insulative housing 1. The spacers 3 are assembled to the insulative housing 1 with the tail portions 203 of the contacts 2 passing through corresponding through-holes 30 thereof. The printed circuit board 4 is embraced between the pair of supporting brackets 15 with soldering pads 40 thereon electrically connecting with the contacts 2 of the second set 22. The first conductors 510 of the first cable 51 are respectively electrically connected with the tail sections 203 of contacts 2 of the first set 21 by conventional means. The second conductors 520 of the second cables 52 are respectively inserted into corresponding apertures 41 of the printed circuit board 4, thereby forming an electrical connection between the second cables 52 and the contacts 2 of the second set 22.
Particularly referring to FIGS. 3–5 and 7, the fixing pusher 6 is attached to the housing 1 along a rear-to-front direction in a pre-seated state. In this state, the leading portion 121 of the housing 1 is partially received in the receiving opening 601, the first stopping projections 604 of the fixing pusher 6 are respectively pushed over the corresponding first protrusions 123 to lock with each other, with the second stopping projection 605 being not in contact with the second protrusion 124 (FIG. 5). Thus, a rearward movement of the fixing pusher 6 is limited by the first protrusions 123 when it is in the pre-seated state. As the leading portion 121 is substantially T-shaped, the fixing pusher 6 will not rotate about an axis in the rear-to-front direction. Finally, the insulative cover 7 is molded with the inner side of the flat plate 120, the rear end of the housing 1 and joint portions of the contacts 2 and the cables 5, thus, the connector assembly 100 is obtained.
Referring to FIGS. 1–7, when the connector assembly 100 is assembled to the panel 8, the mating portion 10 and the pair of guiding projections 109 extend through the mounting opening 80 until a front end of the arm portion 12 abuts against a rear side of the panel 8. The first and second keys 107, 108 respectively pass through corresponding first and second fixing openings 81, 82. The connector assembly 100 is then moved relative to the panel 8 in the longitudinal direction until keys 107, 108 abutting against a front side of the panel 8. The fixing pusher 6 is further forwardly pushed until the filling bars 61 at its forward are brought into mounting opening 80 of the panel 8, thereby mounting the connector assembly 100 onto the panel 8 in a floating manner. Further, this is a final-seated state of the fixing pusher 6 with the second stopping projection 605 thereof being pushed over the second protrusion 124 to lock with second protrusion 124. Thereafter, a rearward movement of the fixing pusher 6 is limited by the second protrusion 124 in this state.
Referring to FIGS. 8–13, another preferable embodiment of the present invention is shown. The arm portion 11 comprises a top wall 110, an opposite bottom wall 111 and a receiving channel 113 defined therethrough between the top wall 110 and the bottom wall 111. Both the top wall 110 and the bottom wall 111 of the arm portion 11 define a first slot 114 at the most outer side thereof with a rear end face thereof in front of an end of the arm portion 11. A recess 115 inwardly recessing from inner surface thereof with a forward end thereof behind a front end of the arm portion 11 and a top opened cutout 117 in communication with the recess 115. The arm portion 11 further forms a forward portion 116 on the forward end of the recess 115 protruding toward the receiving channel 113.
The fixing pusher 9 comprises a main body 90 and a filling bar 91 forwardly extending from the main body 90. Both upper and lower surfaces of the main body 90 have a second stopper 910, a first block 911, a fitting block 912 and a second block 913 thereon, which are arranged in a row along the front-to-back direction. A pair of first stoppers 914 is formed at the most outer side of the main body 90. Two spaced grooves 915 are defined through the main body 90 for providing deforming space of the second stoppers 910 and the fitting block 912 when the fixing pusher 9 is attached to the housing 1′.
Particularly referring to FIGS. 11–13, when the electrical connector 100 is mounted onto the panel 8, the fixing pusher 9 is firstly assembled to the housing 1′ in the rear-to-front direction. The first stoppers 914 respectively interferentially slide into the first slots 114 and front ends of the second stoppers 910 respectively abut against the forward ends of the recesses 115, thus, the fixing pusher 9 is in a first state that it cannot be rearwardly moved. Then, the housing 1′ is inserted into the mounting opening 80 of the panel 8 with keys 107, 108 thereon passing through corresponding fitting openings 81, 82 of the panel 8. Thereafter, the electrical connector 100′ is moved relative to the panel 8 in the longitudinal direction to bring the keys 107, 108 into abutment against the panel 8. Finally, the fixing pusher 9 is further pushed into engagement with the arm portion 11 of the housing 1′ until the filling bar 91 is brought into the mounting opening 80. This is a second state of the fixing pusher 9 that the second stoppers 910 thereof slid over the forward portions 116 of the arm 11 and further protrude into the opened cutouts 117 with rear ends thereof stopped by the forward portion 116 for preventing a rearward movement. In this way which is essentially similar to that of the first embodiment of the present invention, the connector assembly 100′ is mounted onto the panel 8 in a floating manner to form the floating panel mount system 200′.
It should be noted that, since the fixing pushers 6, 9 are made of insulative material and configured in a box-shape, they are enable to be held and operated by hands of an user without worrying about being inadvertently injured. Of course, there is no need of an additional device used for putting the fixing pusher 6, 9 into engagement with the housing 1 and the panel 8.
FIGS. 14–16 show a third embodiment of the invention similar to the second embodiment, wherein the arm portion 11′ of the housing 1′ has the recess 115′ communicating with the cutout 117′ and the forward portion 116′, and a stopper support 118′ at the rear end of the recess 115′, and wherein the fixing pusher 9′ has a main body 90′ with a stopper 910′, the first block 911′ and a fitting block 912′ on one surface, a fitting bar 91′ at a front end, a groove 915′ in a middle portion, and a handle 92′ extending outwardly in a lateral direction perpendicular to the longitudinal direction of the main body 90′. When the fixing pusher 9′ is located in a retracted (rearward) position where the fitting bar 91′ is not effectively located in the mounting opening 80, the rear face of the handle 92′ is seated upon the stopper support 118′ for preventing rearward movement of the fixing pusher 9′ relative to the arm portion 11′, and the stopper 910′ abuts against the forward portion 116′ for preventing forward movement of the fixing pusher 9′ relative to the arm portion 11′; when the fixing pusher 9′ is located in an extended (forward) position where the fitting bar 91′ is effectively located in the mounting opening 80, the stopper 910′ is essentially restrictively located in the cutout 117′.
It can be noted that especially in the first and third embodiments, the fixing pusher is easily accessibly operated from an exterior in a lateral direction rather than and perpendicular to the longitudinal direction of the arm portion, so the operation of the fixing pusher is more controllably friendly for assembling.
Similar to the third embodiment using an L-shaped fixing pusher 9′, FIG. 17 shows an L-shaped fixing/actuating lever 9′′ which is rotatably fixed to the arm portion (not shown) about the pivot 93′′ wherein the cam fitting bar 91′′ is located at a front end of the main body 90′′ and the handle 92′′ is located at a rear end of the main body 90′′. The fixing/actuating lever 9′′ with the associated arm portion of the housing (not shown) initially approaches the mounting panel 8 with the fitting bar 91′′ somewhat invading the mounting opening 82 and with the main body 90′′ in an oblique manner (as shown in the solid lines), and successively rotates to have the main body 90′′ essentially parallel to the housing (as shown in the dashed lines) so as to have the cam fitting bar 91′′ push away the panel 8, rendering a reaction force resulting in the movement of the whole connector housing in a longitudinal direction of the mounting opening along the shown arrow.
Under this situation, the fixing/actuating lever 9′ performs not only the fixing function as provided by the foregoing first, second and third embodiments, but also the actuating function to move the whole connector housing in a longitudinal direction of the mounting opening for offsetting the keys and the fixing openings in the front-to-back direction. In other words, in the first, second and third embodiments the L-shaped moving path of the housing (including the forward and lateral movements) is finished before the fixing pusher is moved; differently, in the fourth embodiment only the forward movement of such an L-shaped movement path is required to be finished before the fixing/actuating lever is operated because the fixing/actuating lever results in the lateral movement of such an L-shaped movement path. Understandably, this pivotal arrangement and the associated advantage are essentially derived from the lateral accessibility/operability of the fixing pusher.
It is also noted that referring to FIG. 13, in the second embodiment the second stopper 910 can be depressed downward through the cutout 117 from the exterior for disengagement from the cutout 17, rendering backward movement of the fixing pusher 9 for easily releasing the connector 100′ from the panel 8. This easy accessibility and operation makes it convenient to assembly or disassemble the connector 100′ with regard to the panel 8.
It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
