Description

  The present invention relates to a contact group and a connector using the contact group.

  A differential transmission method is known in which a differential signal pair consisting of signals having opposite phases is transmitted to two signal lines forming a pair. Since the differential transmission system has a feature that the data transmission speed can be increased, it has recently been put into practical use in various fields.

  For example, when the differential transmission method is used for data transmission between the device and the liquid crystal display, the device and the liquid crystal display are provided with a display port connector designed according to the display port standard. As this display port standard, VESA Display Port standard 1.0 and its version 1.1a are known.

  This display port connector is a kind of connector for differential signals, and has a first connection side for connection to a connection partner and a second connection side for connection to a substrate of a device or a liquid crystal display. Yes. The first connection side configuration is strictly determined by the display port standard because of the relationship with the connection partner, but the second connection side configuration is relatively free.

  This type of differential signal connector is disclosed in Patent Document 1. An example of the differential signal connector will be described with reference to FIGS.

  As shown in FIG. 9, a plurality of conductive contacts 2 are arranged and held in a direction perpendicular to the paper surface in an insulating housing 1.

  FIG. 10 shows an arrangement form of the contacts 2. Each contact 2 has protrusions 3 on both side surfaces thereof. All the protrusions 3 are formed at corresponding positions in the arrangement direction of the contacts 2. The contact 2 is fixed to the housing 1 by the protrusion 3 engaging the inside of the housing 1.

Japanese Patent No. 4439540 (Japanese Patent Laid-Open No. 2008-41656)

  However, the protrusion of the form disclosed in Patent Document 1 becomes an obstacle to narrowing the contact pitch for the following reason.

  One of the reasons is that the distance between adjacent contacts cannot be reduced because the protrusions face each other in the contact arrangement direction.

  Another reason will be described next. It is advantageous in productivity to manufacture a plurality of contacts collectively rather than manufacturing contacts one by one. In that case, the metal plate will be pressed and an intermediate member having a number of leads extending in the same direction from the connecting portion will be punched out. This type of intermediate member is referred to herein as a lead frame. However, in the manufacture of the lead frame, when aiming at narrowing the pitch of the contacts, the press working becomes difficult if the above-described spacing between the protrusions becomes narrow.

  SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a connector that enables a contact pitch to be narrowed without impeding contact holding.

  According to one aspect of the present invention, the contact group of the connector includes four elongated contacts arranged at intervals from each other, each of the four contacts having a deformed portion that changes the contact width. The position of the deformed portion is symmetric when viewed from the center of the arrangement of the four contacts, but there is obtained a contact group characterized in that there are different ones in the longitudinal direction of the contacts.

  According to another aspect of the present invention, there is obtained a connector including the contact group and a molding material that holds the contact group by an insert mold.

  Various other aspects of the present invention will be clarified later.

  ADVANTAGE OF THE INVENTION According to this invention, the connector which made narrow contact pitch possible without inhibiting the holding | maintenance of a contact can be provided.

The lower housing 21 has a pair of posts 21 a for aligning with the upper housing 15. Each of the lower contacts 22 is a horizontal portion 22a arranged along the lower surface of the fitting protrusion 17 of the upper housing 15, and is exposed to the rear of the lower housing 21 from the rear end of the horizontal portion 22a and bent downward. It has a bent portion 22b and a vertical portion 22c extending vertically downward from the bent portion 22b. A lower end portion of the vertical portion 22c of the lower contact 22 is a terminal portion 22d that is inserted into a through hole formed in an attachment target and is fixed by soldering.

  The locator 13 is provided with a pair of positioning bosses 23 that fit into the positioning holes to be mounted on the lower surface. On the rear surface of the locator 13, a plurality of parallel grooves 26 extending in the vertical direction with the same pitch as the vertical portion 16 c of the upper contact 16 are formed. In these grooves 26, the vertical portions 16c of the upper contacts 16 are inserted.

  The connector shell 14 has a plurality of fixing legs 14a and 14b. By engaging these fixing legs 14a and 14b with the object to be attached, the differential signal connector 10 is firmly fixed to the object to be attached.

  An example of a contact group included in the upper contact assembly 11 will be described with reference to FIG.

  The contact group shown in FIG. 4 includes four ground contacts 16-1 spaced apart from each other, and three pairs of signal contacts 16- spaced apart from each other by two ground contacts 16-1. 2 is included. Each ground contact 16-1 is used for ground line connection, and each signal contact 16-2 is used for signal line connection. Four contacts arranged in the order of the ground contact 16-1, the signal contact 16-2, the signal contact 16-2, and the ground contact 16-1 are defined as one contact set 31, and the contact set 31 is one. A contact group is formed by repeating the parts while overlapping. Since all the contact sets 31 have the same configuration, only one of them will be described here.

  In all of the two intermediate signal contacts 16-2 and the two ground contacts 16-1 on both sides thereof, the bent portions 16b are provided at positions aligned in the longitudinal direction of the contacts. That is, the bent portions 16b are provided in a line in the contact arrangement direction. Thus, on one end side in the longitudinal direction of the contacts (lower side in FIG. 4), the four contacts of the contact set 31 are arranged in a line along the upper surface of the fitting protrusion 17 as shown in FIG. On the end side (upper side in FIG. 4), the four contacts of the contact set 31 are arranged in a line along the back surface of the locator 13 by being inserted into the grooves 26 of the locator 13 shown in FIG. 2.

  Each of the four contacts of the contact set 31 has a holding portion 32 that is held in the upper housing 15 of FIG. 3 by mold-in. In other words, the contact group is firmly held by the upper housing 15 by the holding portion 32 engaging with the upper housing 15.

  Each holding portion 32 of the contact is provided with a plurality of, that is, two protrusions 33 as a kind of deformed portion that changes the contact width. These protrusions 33 are integrally formed at corresponding positions on both side surfaces of the contact so that each contact is symmetrical when viewed from the center thereof. In addition, the formation position of the protrusion 33 in the longitudinal direction of the contact differs between the ground contact 16-1 and the signal contact 16-2. In the illustrated example, the protrusion 33 of the ground contact 16-1 is formed on the holding portion 32 on the side close to the bent portion 16b, and the protrusion 33 of the signal contact 16-2 extends from the bent portion 16b of the holding portion 32. Although it is formed on the far side, it may be formed opposite to this. In any case, the protrusions 33 are formed symmetrically when viewed from the center of the arrangement of the two intermediate signal contacts 16-2, that is, when viewed from the center of the arrangement of the four contacts.

  Since the protrusions 33 are formed symmetrically in this way, the symmetry as a differential signal transmission path composed of four contacts is maintained. Therefore, by providing these protrusions 33, the high-frequency characteristics of the connector are maintained. Will not worsen. Further, since the protrusions 33 are formed separately at a plurality of different locations in the longitudinal direction of the contact, the spacing between adjacent contacts can be made relatively wide, and therefore, press working can be easily applied. .

  With reference to FIG. 5, another example of the contact group included in the upper contact assembly 11 will be described. Parts similar to those in FIG. 4 are denoted by the same reference numerals and description thereof is omitted.

  Also in the contact group of FIG. 5, in all of the two intermediate signal contacts 16-2 and the two ground contacts 16-1 on both sides thereof, the bent portions 16b are aligned in the longitudinal direction of the contacts. Is provided. That is, the bent portions 16b are provided in a line in the contact arrangement direction. Thus, on one end side in the longitudinal direction of the contact (lower side in FIG. 5), the four contacts of the contact set 31 are arranged in a line along the upper surface of the fitting protrusion 17 as shown in FIG. On the end side (upper side in FIG. 5), the four contacts of the contact set 31 are arranged in a line along the back surface of the locator 13 by inserting them into the grooves 26 of the locator 13 shown in FIG. 2.

  Each holding portion 32 of the contact is provided with a plurality of, that is, two notches 34 as a kind of deformed portion that changes the contact width. These notches 34 are provided on both side surfaces of the contact, but each contact is formed at a different position in the longitudinal direction of the contact so as to be asymmetrical when viewed from the center. Further, the positions where the notches 34 are formed in the longitudinal direction of the contacts differ between adjacent contacts. In any case, the notches 34 are formed symmetrically when viewed from the center of the array of the two intermediate signal contacts 16-2, that is, when viewed from the center of the array of the four contacts.

  Since the notches 34 are formed symmetrically in this way, the symmetry as a differential signal transmission path composed of four contacts is maintained. Therefore, the provision of these notches 34 provides high frequency characteristics of the connector. Will not worsen. Further, since the notches 34 are formed separately at a plurality of different locations in the longitudinal direction of the contact, the distance between adjacent contacts can be made relatively wide, and therefore, press working can be easily applied. .

  An example of a contact group included in the lower contact assembly 12 will be described with reference to FIGS. 6 and 7.

  The contact group shown in FIGS. 6 and 7 includes four ground contacts 22-1 spaced apart from each other, and three pairs of signals spaced apart from each other by two between the ground contacts 22-1. Contact 22-2. Each ground contact 22-1 is used for ground line connection, and each signal contact 22-2 is used for signal line connection. The four contacts arranged in the order of the ground contact 22-1, the signal contact 22-2, the signal contact 22-2, and the ground contact 22-1 are defined as one contact set 41. A contact group is formed by repeating the parts while overlapping. Since all of the contact sets 41 have the same configuration, only one of them will be described here.

  The two intermediate signal contacts 22-2 and the two ground contacts 22-1 on both sides thereof are provided with bent portions 22b at different positions in the longitudinal direction of the contacts. Thus, on one end side in the longitudinal direction of the contact (upper left side in FIG. 6), the four contacts of the contact set 41 are arranged in a line along one surface, and the other end side (lower right side in FIG. 6). Then, the signal contact 22-2 and the two ground contacts 22-1 on both sides are arranged in different rows. In addition, the pitch of the middle two signal contacts 22-2 out of the four contacts is made larger on the other end side than on the one end side of the contacts.

  Each of the four contacts of the contact set 41 has a holding portion 42 that is held in the lower housing 21 by mold-in. That is, the contact portion is firmly held by the lower housing 21 by the holding portion 42 engaging with the lower housing 21.

  Each holding portion 42 of the contact is provided with a plurality of, that is, two projecting portions 43 as a kind of deformed portion that changes the contact width. These protrusions 43 are the same as the protrusions 33 in the contact group shown in FIG.

  Since the protrusions 43 of the contact group included in the lower contact assembly 12 are also formed symmetrically, the symmetry as a differential signal transmission path composed of four contacts is maintained, and therefore these protrusions The provision of 43 does not deteriorate the high frequency characteristics of the connector. Further, since the protrusions 43 are formed separately at a plurality of different locations in the longitudinal direction of the contact, the distance between adjacent contacts can be made relatively wide, and therefore, press working can be easily applied. .

  Further, in the contact group included in the lower contact assembly 12, a notch similar to the notch 34 in the contact group shown in FIG. Needless to say, similar effects can be obtained.

  FIG. 8A is a plan view showing a state in which the contact group shown in FIG. 7 is pressed from one metal plate, and FIG. 8B is a three-side view showing a state in which the contact group is bent. In the contact set 41, at the position where the pitch of the middle two signal contacts 22-2 is increased, the two ground contacts 22-1 on both sides are provided with relief portions 44 that are separated from the signal contacts 22-2. ing. As a result, in the portion where the relief portion 44 is provided, the distance between the signal contact 22-2 and the ground contact 22-1 is widened, so that formation by press working is easy.
