Abstract | ^ ORIGINAL ^ ABSTRACT "A CONNECTOR AND A METHOD OF FORMING IT" A connector in which a terminal holding portion (23) formed in a connector housing (20) made of synthetic resin is formed with a plurality of substantially aligned press-in holes (28), through which terminal fittings (12) at least partly are pressed, and one or more bored portions (30) are formed in one or more regions of the terminal holding portion (23) substantially parallel to an alignment region (AD) of the press-in holes (28), wherein: one or more continuous material portions (35), through which the synthetic resin material forming the connector housing (20) is continuous, are provided at positions in the bored-portion forming regions (30) substantially corresponding to one or more intermediate positions between the press-in holes (28) adjacent in the alignment direction (AD) without providing any bored portion characterized in that a pair of continuous material portions (35) are provided at the opposite sides of each intermediate position between the press-in holes (28).

Full Text | ORIGINAL The present invention relates to a connector and a method of forming it The present invention relates to a connector of the type for hiding terrnina! fiuings pressed into a connector housing and to a method of forming it? A joini: connector disclosed, for example, in Japanese Unexamined Patent Pubiicats'on No, 2006-32220 is known as an example of the connector of this type,. This joint connector is provided with a connector housing made of syntf-ietic rssin and having fitting recesses 2, into which mating connectors are li'itabte, formed at the opposite sides of a thick partition wall 3, and the partition wal! 3 is formed with a pluraiJ'iy of press-in holes 4 aligned at specified intervals, for example, at each of upper and lower rows as shown In -FIG. 8. iVliddle parts of iermtinal fittings each having tabs at the opposite ends are pressed Into the respective press-in ho|$s 4, so that the terminal fittings are held while the tabs at the both sides project into the opposite fitting recesses 2. Further, bored - portions 5 are formed to prevent surface sinks in areas of the above partition • wall 3 at sides of an alignment region ot the press-in holes 4. As the intervals between terminai fittings have been narrowed to cope with an increased number of required contacts, a phenomenon of cracking resin parts betweera the terminal firiings (press-in holes 4) has come to appear. AccordingSy, ihe present inventors sought the cause to find out the following. As shown in an enlarged part of F!G. 8, if the termlnai fittings are presseo' into Bi'ie pfidss-iri rsoies 4, 'CiOiTipression vorces A a-c- on v iS rssm pan. 2_ ORIGINAL • • (1) The numbers of the tabs in the alignment direction AD and the number of stages of the tabs shown in the foregoing embodiments are merely • examples, and the present invention is similarly applicable to cases Where the number of the aligned tabs and the number of the stages are set differently. (2) The present invention is applicable not only to the joint connectors I illustrated in the foregoing embodiments, but also similarly applicable to j intermediate connectors for connecting two connectors, In which tab-shaped I terminal fittings at least partly are pressed in or fitted to be mounted. In some of I intermediate connectors, adjacent terminal fittings may be separated. Even in I such a case, the problem of cracks simiiaiiy occurs, particularly, if a plurality of aligned teiminal fittings are simultaneously pressed in using a jig or the iil connectors constructed such that a multitude of tab-shaped terminal fittings are pressed in to be mounted. • 0 OR'^'^'AI , LIST OF REFERENCE NUMERALS 10 ... joint terminal 11 ... carrier 12 ... tab (terminal fitting) 15 ... press-in portion 20 ... connector housing I 21 A, 21B ... fitting recess 23 ... intermediate wall (terminal holding portion) 25 ... mounting portion 28 ... pres.5-in hole 30, 30S, 30Sa, SOL ... bored portion i 1 32M, 32U, 32D ... bored-portion forming region • „ 35 ... . continuous materia! portion n ORIGINAL We Claim: 1. A connector in which a terminal holding portion (23) formed in a connector housing (20) made of synthetic resin is formed with a plurality of substantially aligned press-in holes (28), through which terminal fittings (12) at least partly are pressed, and one or more bored portions (30) are formed in one or more regions of the terminal holding portion (23) substantially parallel to an alignment region (AD) of the press-in holes (28), wherein: one or more continuous material portions (35), through which the synthetic resin material forming the connector housing (20) is continuous, are provided at positions in the bored-portion forming regions (30) substantially corresponding to one or more intermediate positions between the press-in holes (28) adjacent in the alignment direction (AD) without providing any bored portion characterized in that a pair of continuous material portions (35) are provided at the opposite sides of each intermediate position between the press-in holes (28). 2. A connector as claimed in claim 1, wherein the respective terminal fittings (12) project substantially side by side from at least one lateral edge of a carrier (11). 3. A connector as claimed in claim 2, wherein base ends of one or more terminal fittings (12), preferably connected with the carrier (11), are widened in a specified length range to form one or more press-in portions (15). 4. A connector as claimed in one or more of the preceding claims, wherein the one or more bored portions (30) comprise one or more first bored portions (30S) preferably in the form of a horizontally long groove having a vertical width larger than the thickness of the terminal fittings (12), a horizontal width of more than about 1.5 times the width of the terminal fittings (12) and/or a depth less than about 2/3 of the thickness of the terminal holding portion (23). 5. A connector as claimed in one or more of the preceding claims, wherein the one or more bored portions (30) comprise one or more second bored portions (30L) making openings in the back surface of the terminal holding portion (23), preferably in a fitting recess (21) provided therein. 6. A connector as claimed in claim 5 in combination with claim 4, wherein the second bored portions (30L) are in the form of through holes having a vertical width slightly larger than about 1.5 times that of the first bored portions (30S). 7. A connector as claimed in one or more of the preceding claims, wherein one or more mounting portions (25) are provided for one or more joint terminals (10) comprising the terminal fittings (12) at one or more stages while being spaced apart by a specified distance. 8. A method of forming a connector comprising the following steps: forming a terminal holding portion (23) in a connector housing (20) made of synthetic resin with a plurality of substantially • ORIGINAL aligned press-in holes (28), forming one or more bored portions (30) in one or more regions of the terminal holding portion (23) substantially parallel to an alignment region (AD) of the pressin holes (28) providing one or more continuous material portions (35), through which the synthetic resin material forming the coimector housing (20) is continuous, at positions in the bored-portion forming regions (30) substantially corresponding to one or more intermediate positions between the press-in holes (28) adjacent in the aligrraient direction (AD) without providing any bored portion (30), and at least partly pressing one or more terminal fittings (12) into press-in holes (28) characterized in that a pair of continuous material portions (35) are provided at the opposite sides of each intermediate position between the press-in holes (28).
