Description
- The present invention relates to a connector plug which is provided with a relatively large number of pin contacts and shielded electromagnetically and to a connector socket for connection with a mating connector plug.
- Since conventional connectors with a relatively large number of pin contacts have oblong bodies, there is a limit to the number of such connectors which can be mounted on a printed-circuit board along its one marginal edge. On account of their oblong bodies, connection and disconnection of these connectors are somewhat troublesome when they are closely arranged side by side. Furthermore, the prior art connectors are not sufficiently shielded from electromagnetic noise.
- The document EP-A-0040941 discloses a connector plug and a connector socket wherein the square-sectioned insulating body of the connector is housed in a shielding member defined by an upper and a lower half metal shell, the rear semicylindrical portions of which are clamped by a split metal cylinder against a shielded cable. Apertures are formed in the upper half metal shell for engagement with protuberances formed on springs which are formed integrally with a metal cover of a mating connector socket. The apertures are the only locking means provided for the known connector.
- The document US-A-4265503 discloses a multi-contact connector with a locking mechanism, wherein a disc-shaped insulating body is housed in a sleeve and the locking mechanism is provided on the outer periphery of the sleeve. This arrangement is intended to allow a relative movement between the contact housing sleeve and an insulating collet shell so that pin contacts can be inserted into receptacles of a mating connector (see Fig. 16 and then Fig. 17) by rotating a cam after having completed the locking engagement between the collet shell and a flange part of the mating connector. Moreover, this locking mechanism requires two coiled springs for forwardly biasing a sleeve and a slider independently of each other relative to the collet shell, thus inevitably making the connector thick. This reference does not mention anything about electromagnetic shielding.
- It is therefore an object of the present invention to provide a multipin connector plug which can be mounted, in relatively large numbers, on a printed-circuit board and is easy of connection and disconnection and sufficiently shielded electromagnetically. It is a further objective to provide a mating connector socket.
- According to the invention the objective concerning the connector plug is solved with a connector plug comprising the features of claim 1. The objective concerning the connector socket is solved by a connector socket comprising the features of claim 5.
- The multipin connector plug of the present invention, employs a square-shaped body of an insulating material. The insulating body has a plurality of contact housing holes bored therethrough and arranged in a matrix form. The contact housing holes each have housed therein a pin contact, the front end portion of which projects out of the insulating body for connection to a socket contact of the mating connector and the rear end of which is connected to one of cords of a shielded cable. The shielded cable is firmly clamped by a cable clamper made of metal, with the shield (or braid) of the former connected to the inner surface of the latter. The cable clamper is snugly fitted in the rear end portion of a shielding member made of metal and the above-mentioned insulating body is similarly fitted in the front end portion of the shielding member.
- Since the insulating body of the multipin connector of the present invention is square, many contacts can be provided together closely and the height and width of the connector are substantially equal. Accordingly, the multipin connector of the present invention is easy to handle and can be mounted on a printed-circuit board in greater numbers than the conventional oblong multipin connectors.

Reference numeral 11 indicates a body of an insulating material which is square in shape and hence has substantially square front and rear end faces. Theinsulating body 11 hascontact housing holes 12 bored therethrough in its front-to-back direction and arranged in a matrix form with five rows and five columns in this embodiment. Thecontact housing holes 12 each have housed therein apin contact 13, the front end portion of which forms acontact portion 13a projecting out of the front end face of theinsulating body 11 and the rear end portion of which forms acord connecting portion 13b. - A shielded
cable 14 has a plurality ofcords 15, each of which is fixedly connected at one end to thecord connecting portion 13b of one of thepin contacts 13. Acable clamper 16 made of metal firmly clamps the shieldedcable 15 inserted therethrough, with its shield (or braid) 17 folded back onto the cable armor. Theshield 17 is soldered to the front end of thecable clamper 16, as indicated 18 in fig. 3. Thecable clamper 16, pressed around a clampingportion 19 thereof, fixedly clamps thecable 14. - The
cable clamper 16 is fitted into and fixed to the rear end portion of atubular shielding member 21 made of metal. Thecable clamper 16 has, on the radially outside of the front end portion thereof, anengaging portion 22 formed concentrically and integrally therewith, theengaging portion 22 being received in the rear end portion of theshielding member 21 and soldered thereto, as indicated by 23 in Fig. 3. - The
insulating body 11 is held in the forward portion of theshielding member 21. The forward portion of theshielding member 21 is square-sectioned in conformity to the insulatingbody 11. Theinsulating body 11 is pressed into the square-sectioned portion from behind through the rear end portion of theshielding member 21 whose inner diameter is greater than that of the square-sectioned portion. Theinsulating body 11 has aflange 25, which abuts against astepped portions 24 of theshielding member 21 when theinsulating body 11 is fitted therein. Acircumferential ridge 26 extending around the outer periphery of theinsulating body 11 is engaged with alug 27 of theshielding member 21 so that theinsulating body 11 is held in position. - The multipin connector of this embodiment is provided with means for locking with the mating connector. A
protector portion 31 is fixedly mounted on the rear end portion of theshielding member 21 in a manner to surround thecable clamper 16. The front end portion of theprotector portion 31 engages the rear end portion ofshielding member 21, and acover 32 covering theshielding member 21 is provided in a manner to be movable back and forth. Provided between theshielding member 21 and thecover 32 is an elastic slidingpiece 33 which is slidable back and forth relative to thecover 32.Guide ridges sliding piece 33 are formed integrally with theshielding member 21. Theshielding member 21 has acutaway 35 in opposing relation to the forward end portion of thesliding piece 33 so that the front end portion of thesliding piece 33 may bend toward the axis of the connector for engagement with a part of the mating connector inserted into the front end portion of theshielding member 21. Thesliding piece 33 is biased forward at all times. That is, a coiledspring 36 is wound around theshielding member 21 between arear end portion 33a of thesliding piece 33 and the front end of theprotector portion 31. For unlocking the connector from the making connector, therear end portion 33a of thesliding piece 33 is pulled back by a steppedportion 32a of the slidingcover 32 against the biasing force of thecoiled spring 36 so that aprojection 38 of aspring piece 37 can be submerged below the top level of theguide ridges - The
spring piece 37 is disposed opposite thesliding piece 33 on the outside thereof and held between theguide ridges spring piece 37 has theprojection 38 at its front end portion, and the front end of theprojection 38 engages abridge portion 39, preventing thespring piece 37 from movement in a direction opposite from thesliding piece 33. - Next, a description will be given, with reference to Figs. 5 to 8, of the mating connector for connection to the multipin connector of the present invention described above. A square-sectioned
body 41 of an insulating material has, in its forward portion, contacthousing holes 42 bored therethrough and arranged in a matrix form, and eachcontact housing hole 42 houses therein asocket contact 43. The backward portion of theinsulating body 41 is hollow and its rear end is open. The bottom of the backward portion of thebody 41 hasslots 41a extending lengthwise thereof and open at the rear end thereof. As shown in Fig. 8, thesocket contacts 43 extend backward and are bent down, at right angles, at different positions in their lengthwise direction so that their bent portions, each forming a terminal 44, may lie apart. In this example, since it is difficult to make such laterally closely-packedsocket contacts 43 out of a single sheet of metal,socket contact arrays 43a and 43b are each made of a sheet of metal and they are assembled together so that theirsocket contacts 43 may lie alternately with each other. The terminals 44 (44a, 44b) of thesocket contacts 43 project out ofcorresponding slots 41a made in the bottom of the insulatingbody 41 at the rear end portion thereof. The bottom of the insulatingbody 41 open at the rear end portion is covered with abottom panel 45 which haslateral slots 45a through which terminal coupling portions 40 (40a, 40b) project downwardly thereof. Theterminal coupling portions 40 are cut off after assembling. - The insulating
body 41 is covered with a rectangulartubular shielding member 46, which is, in turn, covered with a square-sectionedtubular case 47 made of an insulating material. When this connector is coupled with the multipin connector shown in Figs. 1 to 4, the forward portion of the shieldingmember 46 is fitted into the forward portion of the shieldingmember 21 of the multipin connector. The forward portion of the shieldingmember 46 has a plurality ofslots 50 so that it may elastically engage the shieldingmember 21. The top surface of the shieldingmember 46 has a lockingprotrusion 48 formed by embossing. Thecase 47 has arecess 49 formed in its inner surface in opposing relation to theprotrusion 48 and its vicinity, for receiving thebridge portion 39 and theguide ridges case 47 has ahole 51 made in aceiling 49a of therecess 49 in opposing relation to theprotrusion 48. - When this mating connector is coupled with the multipin connector, the
bridge portion 39 and theguide ridges recess 49, as shown in Fig. 9A. When further pressing the mating connector into the multipin connector, theprojection 38 of thespring piece 37 is urged against theceiling 49a of therecess 49, and consequently thespring piece 37 is pushed downward, thereby elastically bending the front end portion of the slidingpiece 33 down. Accordingly, theprotrusion 48 strikes against the tip of the slidingpiece 33, sliding it backward, as shown in Fig. 9B. When the front end portion of the shieldingmember 21 is further forced into therecess 49, theprojection 38 of thespring piece 37 moves into engagement with thehole 51, as depicted in Fig. 9C. That is, the slidingpiece 33 is disengaged from theprotrusion 48 and restored to its initial form and, by the force of the coiledspring 36, thespring piece 33 overrides theprotrusion 48, locking theprojection 38 in thehole 51. In this state, thepin contacts 13 are each held in and engaged with the correspondingsocket contact 43. - To unlock the multipin connector from the mating connector, the
cover 32 needs only to be pulled back against the biasing force of the coiledspring 36, in consequence of which the slidingpiece 33 is also pulled back and out of engagement with theprotrusion 48, permitting easy disengagement of theprojection 38 from thehole 51. - Incidentally, the
coiled spring 36 need not always be wound around the shieldingmember 21 but instead a plurality of small windings may also be utilized so as to reduce the size of thecover 32, as shown in Fig. 10. - As described above, the multipin connector of the present invention employs a square-sectioned insulating body, which can hold contacts concentratively and the four sides of the square section can be made substantially equal to one another; accordingly, the multipin connector of the present invention is relatively round as a whole and can easily be gripped for connection to and disconnection from the mating connector. A number of such multipin connectors can be mounted on one marginal edge of a printed circuit board. Moreover, the internal structure from the contacts to the cable connecting portion is disposed within the shielding
member 21, and hence is shielded from electromagnetic waves. Besides, since the locking mechanism is disposed outside the shieldingmember 21 in the example described above, the electro-magnetic shield is not affected by the locking mechanism.
