Abstract
Description
- This invention relates to a contact fixing structure for an electrical connector, particularly a miniaturized multi-contact connector.
- Recently, various kinds of electronic parts have been miniaturized. For example, densities of parts loaded in printed circuit boards have been considerably increased, so that the numbers of terminals for connecting the printed circuits to external circuits have been also considerably increased. In order to connect the printed circuit boards to the external circuits, therefore, it is required for the connectors to have a great number of contacts irrespective of outer diameters of the connectors being substantially equal to those of prior art connectors.
- To this end, diameters of male contact pins and sizes of female contacts for receiving the male contacts are made as small as possible. At the same time, the male contact pins 1 are arranged with required intervals in plural rows shifted so as to locate each contact between contacts in adjacent rows, and the female contacts are arranged in similar rows for receiving the male contact pins as shown in Fig. 1. In this manner, contact tails 1b of the contact pins in the rows b extend between contact tails 1a of the contact pins in the rows a in order to accomplish the multi-contacts. In the example shown in Fig. 1, the contact tails extend perpendicularly to the rows of the contacts. However, contact tails may extend in directions the same as those of the rows of the contacts. In this case, diameters of male contact pins are often less than a few times a tenth of one mm and female contacts are also small corresponding thereto. In fixing such very small contacts in an insulating housing, therefore, it is not an easy matter that the contact is provided on its one side with a
pawl 2 adapted to engage in an anchoringshoulder 3a formed in the insulating housing 3 so as to fix the male contact thereto as shown in Fig. 2 as in the prior art. In this case, accordingly, the contact is forced into an insert aperture of the insulating housing with an interference, thereby fixing the contact in the aperture. However, as the contact is very small and weak in mechanical strength as above described, it is likely to be bent to give rise to irregularity in intervals between the contacts, which makes difficult the practical use of such small contacts. - It is a primary object of the invention to provide an improved contact fixing structure for an electrical connector, particularly miniaturized multi-contact connector, which eliminates all the disadvantages above described and is capable of securely fixing contacts to an insulating housing without difficulties.
- In order to achieve this object, the contact fixing structure for an electrical connector including an insulating housing, a fixing plate and at least one contact having a contact element and a thin contact tail electrically connected to said contact element and extending substantially perpendicularly to said contact element according to the invention comprises a fixing plate fitting portion formed in said insulating housing for fitting said fixing plate therein, a contact insert aperture formed in said fixing plate fitting portion to fix said contact element inserted in said contact insert aperture by the fixing plate fitted in said fixing plate fitting portion of said insulating housing, and a contact tail extending groove formed in at least one of said insulating housing and said fixing plate and being somewhat larger than said contact tail for extending said contact tail of said contact out of said insulating housing when said contact element is inserted in said contact insert aperture and fixed therein by said fixing plate.
- In a preferred embodiment of the invention, a plurality of contact insert apertures for a plurality of contacts are arranged in plural rows, each r ow being shifted to each other to locate each aperture between the aperture of the adjacent rows, and on a side of the contact fixing plate in opposition to a recess forming the fixing plate fitting portion there are provided contact tail horizontally extending grooves starting from locations corresponding to positions of the contact insert apertures of the insulating housing for horizontally extending contact tails of the contacts.
- Both longitudinal side edges of the insulating housing formed by the recess forming the fixing plate fitting portion may be formed with contact tail horizontally extending grooves for horizontally extending the contact tails of the contacts.
- Moreover, both longitudinal side edges of the fixing plate may be formed with contact tail vertically extending grooves corresponding to the contact tail horizontally extending grooves of the insulating housing for vertically extending the contact tails of the contacts.

- Figs. 3a-3c illustrate one embodiment of the invention, wherein a contact element (contact pin) 6a is formed with an enlarged
diameter head 6a' to which athin contact tail 6a is electrically connected substantially perpendicular to thecontact element 6a to form acontact 6 as shown in Fig. 3a. Aninsulating housing 4 is formed with acontact insert aperture 4c having a slightly enlargedaperture 4c' corresponding to thehead 6a' of thecontact element 6a. The insulatinghousing 4 is further formed with afitting recess 4b for receiving afixing plate 5 for fixing thecontact 6 and with agroove 4e through which thecontact tail 6b extends as shown in Fig. 3b. With this arrangement, after thecontact element 6a has been inserted into thecontact insert aperture 4c of theinsulating housing 4 with thecontact tail 6a being arranged in thegroove 4e, thefixing plate 5 is fitted in thefitting recess 4b so that thehead 6a' of thecontact element 6a is urged and fixed to thefitting recess 4b with the aid of a shoulder formed by theapertures Reference numeral 5e denotes a second groove making possible to extend thecontact tail 6b in a direction of thegroove 4e.Reference numeral 5c denotes a groove for extending thecontact tail 6b in a direction in parallel with thecontact element 6a as the case may be as shown by dotted lines in Fig. 3c. - Figs. 4a-4d are exploded perspective views of one embodiment of the connector according to the invention, which is capable of extending contact tails in directions perpendicular to and in parallel with contact elements arranged in shifted plural rows. This connector comprises an
insulating housing 4, acontact fixing plate 5 andcontacts 6 and 7. These members are assembled as shown in perspective views of Figs. 5a and 5b and sectional views of Fig. 6, in order to fix thecontacts 6 and 7 to the insulating housing. These members are constructed as follows. - As shown in Fig. 4a, the
insulating housing 4 is formed with a contact fixingplate fitting recess 4b which includes at both ends press-fittingfixing grooves 4a. A bottom of therecess 4b is formed withinsert apertures 4c (4c') for male contact pins orcontact elements 6a (6a') and 7a (7a') in four rows a, b, a' and b' shifted to each other so as to locate each insert aperture between the insert apertures in the adjacent rows. Moreover, both longitudinal side edges 4d of the insulatinghousing 4 formed by therecess 4b are formed with contact tail horizontally extendinggrooves 4e equally spaced corresponding to theinsert apertures 4c, respectively, for horizontally extending the contact tails therein. - As shown in Fig. 4b, the
contact fixing plate 5 has an outer configuration and a size so as to be press-fitted in therecess 4b of the insulatinghousing 4 and is provided at ends withfitting protrusions 5a adapted to be fitted in the fixinggrooves 4a formed at both the ends of therecess 4b of the insulatinghousing 4. Moreover, bothlongitudinal side edges 5b of thecontact fixing plate 5 are formed with contact tail vertically extendinggrooves 5c corresponding to the contact tail horizontally extendinggrooves 4e formed in the side edges 4d of the insulatinghousing 4. On a side of thecontact fixing plate 5 in opposition to the contact fixing platefitting recess 4b there are provided first contacttail extending grooves 5d extending from locations corresponding to theinsert apertures 4c in the rows a and b' to the contact tail vertically extendinggrooves 5c and the second contacttail extending grooves 5e longer than thegrooves 5d and extending from locations corresponding to theinsert apertures 4c in the rows b and a' to the contact tail vertically extendinggrooves 5c. - As shown in Figs. 4c and 4d, the
contacts 6 and 7 include contact pins orcontact elements contact tails contacts 6 and 7 are bent according to configurations of contact tail extending passages different in length formed by theinsert apertures 4c of the insulatinghousing 4 and the first and second contacttail extending grooves grooves contact fixing plate 5. - In assembling these members, the contact pins 6a and 7a are inserted into the
insert apertures 4c and theircontact tails grooves 4e as shown in Fig. 5a. Thereafter, while thecontact tails grooves 5c, thecontact fixing plate 5 is fitted and fixed into thefitting recess 4b of the insulatinghousing 4 to form a receptacle connector as shown in Figs. 5b and 6. - As can be seen from the above description, while the
contact tails grooves 4e, the contact pins 6a (6a') and 7a (7a') having shoulders are inserted into theinsert apertures 4c (4c') having shoulders somewhat larger than diamet ers of the contact pins. Thereafter, thecontact fixing plate 5 is press-fitted in thefitting recess 4b to fix the contact pins 6a (6a') and 7a (7a') in position with the aid of thecontact fixing plate 5 and the insulatinghousing 4 as explained by referring to Fig. 3. It is not required to make diameters of contact pins and insert apertures exactly coincident with each other, which would otherwise be required in case that the contact pins are press-fitted in fixing apertures of an insulating housing as in the prior art. Accordingly, even if contact pins or contact elements are thin and weak due to multi-contacts, the contact pins are securely fixed in position without irregularity in interval caused by bending of the contact pins in inserting them into insert apertures, thereby enabling the assembly of the connector to be simplified. On the other hand, the contact tails extend through the respective extendinggrooves contact fixing plate 5, the contact tails may be located in therespective grooves insert apertures 4c by one operation. With this arrangement, the assembling of the connector is simplified and the connecting pieces 8 serve to maintain substantially constant the distances between the contact tails to make easy the insertion of the contact tails into the horizontally extendinggrooves 4e and hence the assembly of the connector. Moreover, as the contact tails are arranged in the extendinggrooves 5e (5d) and 4e of thecontact fixing plate 5 and the insulatinghousing 4, the insulation between the adjacent contact tails is maintained under better conditions. - The invention has been explained in reference with fixing of male contacts in the above explanation. In case of female contacts, as shown in the cross-section of Fig. 7, after the contact sockets 6al and 7al have been inserted into
contact insertion apertures 4c of an insulatinghousing 4, contact elements of the contacts (for example, sockets in this case) are fixed in position by means of acontact fixing plate 5 such thatthin contact tails tail extending grooves 5c, thereby achieving the same effect as above described. In this case, moreover, it is not needed to form shoulders required in the male contact pins, and the contact sockets and contact tails may of course be directly connected. Although thecontact tails 6b have been explained to extend straight out of the insulatinghousing 4 without using any bent extending passage in this embodiment, it is preferable to use bent passages because tensile forces act directly on connections between thecontact tails 6b and the contact elements (sockets) when the contact tails are subjected to tensile forces, if the passages are straight. - Fig. 6 illustrates one example wherein the insulating
housing 4 is provided with the contact tail horizontally extendinggrooves 4e, and thecontact fixing plate 5 is provided with the contact tail vertically extendinggrooves 5c, thereby enabling thecontact tails grooves 5c of acontact fixing plate 5 are not needed as shown in Fig. 8a. If contact tails extend only in parallel with the contact pins, horizontally extendinggrooves 4e of an insulatinghousing 4 are not needed as shown in Fig. 8b. - While the invention has been particularly shown and described with reference to preferred embodiments thereof, it will be understood by those skilled in the art that the fo regoing and other changes in form and details can be made therein without departing from the spirit and scope of the invention.
