[0002]

2. Description of the Related Art When a connector is surface-mounted on a substrate, the movement of the connector is automated using a suction nozzle. That is, the connector is assembled by attaching a suction member to the connector, and the suction nozzle of the robot arm is sucked together with the connector by the suction nozzle of the robot arm, and the connector is moved to a predetermined position on the board. It is placed on.

As an example of this, a connector shown in FIG. 10 is disclosed in Japanese Utility Model Laid-Open No. 5-31188. The housing 102 of the connector 100 includes a plurality of contacts 1
04 and an upward fitting portion 106. The connector suction member 110 includes a substantially rectangular flat plate portion 112 and the flat plate portion 1.
It has a pair of mounting legs (hereinafter simply referred to as legs) 114 hanging down from the reference numeral 12. The suction member 110 is attached to a substantially central portion of the opening 108 of the fitting portion 106, and the leg 114 is inserted into the opening 108 and fixed to the housing 102 by frictional engagement with the inner surface of the side wall 103.

In the case of this conventional example, there is no means for positioning the suction member 110 in the longitudinal direction of the housing 102, so that accurate positioning is difficult. If the suction member 110 is displaced and attached to the housing 102, the balance may be lost at the time of suction, and the housing 102 may be inclined or the suction may not be sufficient.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings. 1 to 4 show a front view, a plan view, a bottom view, and a side view, respectively, of a connector suction member (hereinafter, simply referred to as a member) 1 of the present invention.

First, referring to FIG. 1, a member 1 is formed by integral molding of a resin, and has an elongated flat plate portion 4 having a flat upper surface 2 and four mounting legs (hereinafter simply referred to as “hanging legs”) hanging from the flat plate portion 4. 6), a pair of ribs 8 along the longitudinal direction of the member 1, and three pairs of tongue pieces (positioning portions) 10, 10 and 20, 20, 2, 2 located near both ends in the longitudinal direction.
0 ′ and 20 ′ (FIG. 3). The leg 6 is provided integrally with the rib 8 at a distance from the side edge of the flat plate portion 4 and formed by increasing the thickness of the rib 8.
a. The tips of the legs 6 and the ribs 8 are at the same distance from the flat plate portion 4. The tongue piece 10 is located on the outermost side of the flat plate portion 4, and the tongue piece 20 is located on the inner side while being separated from the tongue piece 10. Tongue piece 1
Numerals 0 and 20 extend downward perpendicular to the flat plate portion 4, and respective tips 10 a and 20 a slightly protrude from the tip 8 a of the rib 80.

The planar shape of the member 1 will be described with reference to FIG. The center of the flat plate portion 4 is formed as a wide suction portion 26 that is sucked by the nozzle. On both sides of the suction part 26, extended parts 30 having a narrower width than the suction part 26 are formed via a narrow part 28. A protruding portion 32 is formed at the tip of the extension portion 30, and serves as a finger hook when attaching or detaching. The aforementioned legs 6 are formed on both sides of the constricted portion 28 facing each other. Both ends of the extension portion 30 have a contour shape that matches the fitting portion of the connector to be attached.

Referring now to FIG. 3, two ribs 8,
It can be easily seen that 8 'extends linearly along the length of member 1 to extension 30. The ribs 8 and the ribs 8 'extend parallel but are clearly shown passing through the legs 6, 6 and forming thick tongues 20, 20' at both ends, respectively. What should be noted here is the tongue piece 20 '
Is that the length of the member 1 in the longitudinal direction is slightly shorter than that of the tongue piece 20, and the outermost end 20 b ′ is displaced from the outermost end 20 b of the tongue piece 20. The reason will be described later. Further, the tongue pieces 10, 10 are arranged symmetrically to face each other. This curve has a shape conforming to the outer shape (substantially D-shaped) of the fitting portion 52 of the connector 50 (FIG. 6) to be attached.

FIG. 4 shows the rectangular tongue piece 10, the convex part 32 located at the upper end thereof, and the side edge 26a of the suction part 26 projecting to both sides.

FIG. 5 is an enlarged sectional view taken along line 5-5 in FIG. It can be seen that the legs 6, 6 are molded integrally with the flat plate portion 4, and the projections 6a, 6a are formed on the outer side of the tip. A tapered portion 6b is formed at the tip of the leg 6 to serve as a guide for mounting.

Next, a state in which the member 1 is mounted on the connector will be described with reference to FIGS. FIG. 6 shows a state in which the member 1 is mounted on the fitting portion 52 of the connector 50 having a relatively small number of poles. The connector 50 includes a housing 54 and a contact 5.
6 and a metallic shield shell (hereinafter simply referred to as a shell) 60 attached to the outer surface of the housing 54. The shell 60 has a fitting portion 52, an outer extension 62 extending on the side surface of the housing 54, and a latch tongue 64 that engages with a latch projection 58 of the housing. The fitting portion 52 has a fitting recess 53 (FIG. 7) for receiving a mating connector.
Eight dimples 6 recessed inward on the side surface of the fitting portion 52
6 are formed. The dimple 66 is for making a ground connection by contacting a shield shell of a mating connector (not shown). The tongues 20, 20 'of the member 1 are inserted and locked into the inner surface of the longitudinal end of the shell 60, that is, the inner surface of the fitting recess. At this time, since the longitudinal outer edges 20b, (20b ') of the tongue pieces 20, 20' are dimensioned according to the inner surface shape of the fitting portion 52, the member 1 is positioned by this. At the same time, the leg 6 has a dimple 66
, Whereby the member 1 is fixed to the connector. At this time, the outermost tongue piece 10 is not engaged with the longitudinal end of the fitting portion 52. Accordingly, the member 1 includes a tongue piece 20,
Positioning is performed only by 20 '.

FIG. 7 is an enlarged sectional view taken along the line 7-7 in FIG. At the approximate center of the housing 54, an upright central rib 70 is formed, and the contact 56 arranged opposite to the central rib 70 can be seen. It can be understood that the shell 60 is arranged on the outer periphery of the housing 54 and the dimple 66 is formed on the fitting portion 52. The protrusion 6a of the leg 6 is engaged with the lower part of the dimple 66. The leg 6 is inserted between the inner surface of the fitting portion 52 and the tip of the contact 56.

FIG. 8 is a front view showing a state in which the same member 1 is attached to a connector 50 'having more poles than the connector 50 shown in FIG. In the description, similar parts are denoted by the same reference numerals. Connector 50 'is connector 5
The difference from 0 is that the dimension of the fitting portion 52 'in the longitudinal direction is large due to the difference in the number of poles, and the dimension of the fitting portion 52' in the height direction is large. Dimple 6 of fitting part 52 '
The positional relationship between 6 ′ and leg 6 ′ is the same. Since the length of the fitting portion 52 'is large, when the member 1 is mounted, the inner surface of the outer tongue piece 10 receives the outer end portion 55' of the fitting portion 52 '. Since the inner surface of the tongue piece 10 is formed in the same outer shape as the corresponding outer surface of the fitting part 52 ', the tongue piece 10 is stably positioned with respect to the fitting part 52'.

FIG. 9 is an enlarged sectional view taken along line 9-9 in FIG. Shell 60 'of connector 50' and central rib 7
It is well shown that the 0 'height dimension is long. However, it can be clearly understood that the positional relationship between the leg 6 'and the dimple 66' is the same, and the manner of attachment is basically the same.

Although the preferred embodiment of the present invention has been described in detail above, it is easily understood by those skilled in the art that the present invention is not limited to the present embodiment and various modifications and changes are possible. For example, another tongue piece may be provided inside the tongue piece 20 in the longitudinal direction separately from the tongue piece 20, and this may be used as a tongue piece for attachment to a connector having a smaller number of pins than the connector 50. Alternatively, the outer surface of the tongue piece 10 may be inserted and attached to the inner surface of the fitting portion of another connector larger than the connector 50 '.

[0022]

According to the present invention, a substantially flat connector suction member for a connector and a connector assembly using the same have a plurality of pairs of positioning portions which are displaced in the longitudinal direction, and have different lengths depending on the positioning portions. The suction member can be shared and mounted on the connector having the fitting portion. Therefore, it is possible to avoid problems such as inclination and insufficient suction when mounting the connector. Further, there is no need to prepare a plurality of types of suction members, the cost can be reduced, and the management of parts is easy. In particular, it is important that this kind of suction member be shared and inexpensive because it is discarded after mounting the connector.
