The housing 52 is provided with second insertion holes 78 on the two second side walls 66 in which a required number of plug contacts 56 are respectively mounted, and is fixed by press-fitting, hooking (lance), welding, or the like. . The shape and size of the second insertion hole 78 is appropriately designed in consideration of the size, shape, holding force, etc. of the plug contact.
The two second side walls 66, the second flange 70, and the second bottom wall 68 form a fitting port 5 into which the fitting portion 7 of the receptacle connector 20 is inserted. The fitting port 5 only needs to be fitted with the fitting portion 7 of the receptacle connector 20 which is a mating connector, and the size and shape are in line with the size of the receptacle connector, and contact stability, connector miniaturization and workability are achieved. It is designed appropriately considering the above.
The second flange 70 is provided with a fourth insertion hole 79 into which the first fixing tool 54 is inserted and fixed, and is fixed by press-fitting, hooking (lance), welding or the like. In this embodiment, it is fixed by press fitting.
Next, the 1st fixing tool 54 which is the point part of this invention is demonstrated. The first fixture 54 is made of metal and is manufactured by a known press working. Since the material of the first fixture 54 is required to be springy or conductive, examples thereof include brass, beryllium copper, and phosphor bronze. The first fixing member 54 mainly includes at least three engaging portions 76 and 77 that engage with the second fixing member 25, a fourth fixing portion 72 that is fixed to the housing 52, and a fourth connection that is connected to the substrate. Part 74.
In consideration of balance, the first fixtures 54 are disposed on both sides in the longitudinal pitch direction. The first fixing member 54 has a substantially plate-like piece, has second engaging portions 77 protruding on both sides in the width direction, and is protruded into the fitting port 5 on the elastic piece 80 folded back in the center portion in the width direction. One engaging portion 76 is provided. The first engaging portion 76 of the first fixture 54 has a convex portion 761 shape, and the second engaging portion 48 has a protruding portion 771 shape protruding outward. The first engaging portion 76 of the first fixture 54 is elastic.
The shape and size of the convex portion 761 (the first engaging portion 76) and the protruding portion 771 (the second engaging portion 77) are the same as the plate-like portion 461 (the first engaging portion) of the second fixture 25. Stop portion 46) and recess 481 (second locking portion 48) can be engaged with each other as long as a stable holding force can be obtained and an electric conduction can be obtained. Design appropriately considering miniaturization and the like.
The fourth fixing portion 72 is a portion that is held in the fourth insertion hole 79 of the housing 52. In this embodiment, it is held by press-fitting, but any method may be used as long as it can be held, and it is appropriately designed in consideration of downsizing of the connector, strength, holding force and the like.
The fourth connection part 74 is a part connected to the substrate. The fourth connection portion 47 may have any shape (type) as long as it can be connected to the substrate, but in the present embodiment, it is a surface mount (SMT) type. For example, a dip type may be used.
In this embodiment, the first fixing device 54 provided with an engaging portion and the second fixing device 25 provided with a locking portion have been illustrated and described. The part may be reversed. That is, a locking part may be provided on the first fixing tool 54 side, and an engaging part may be provided on the second fixing tool 25 side.
As an application example of the present invention, it is used in an electrical connector 10 used in an electric device or an electronic device such as a mobile phone or a small personal computer (PC), and in particular, it can be sufficiently held against warping, The present invention relates to an electrical connector 10 having a structure using a fixture that can also be used as a power source.
