Embodiment Construction

[0071] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0072] Figure 5 It is an external view showing an upper side card edge connector which is one embodiment of the card edge connector of the present invention together with a lower side connector 1 used as a set. Figure 5 Part (a) is a top view, and part (b) is a right side view. in addition, Figure 5 The upper side card edge connectors shown can also be used independently of the lower side connectors.

[0073] Here, the upper card edge connector 3 (hereinafter referred to as the upper connector 3) as an embodiment of the present invention will be mainly described. figure 1 and figure 2 In the description of the lower connector 1 , only the matters necessary for the relationship with the upper connector 3 will be described.

[0074] Figure 5 The shown upper side connector 3 is mounted on a mother substrate M (refer to Figure 7 ) on which, for example, a sub-s...

Abstract

A card edge connector (3) includes an insulation housing (31) which receives a child board, and a pair of latch arms (33) which project from both ends of the insulation housing (31) and hold the child board and which are formed by bending metal plates. Each of the latch arms (33) includes a hold arm (331) and a support arm (333) which is formed through a folded-back portion (332) folded back outwardly, from the hold arm (331) by 180°. The support arm (333) includes a first support section (336) which extends forward from the folded-back portion (332) and which bends outwardly in front of a front edge (332a) of the folded-back portion (332). The support arm (333) also includes a second support section (337) which is separated from the first support section (336) by a long hole or slot and is connected to the first support section at a rear edge (332b) of the folded-back portion (332). The second support section (337) is bent outwardly at a location closer to the insulation housing (31) than the front edge (332a) of the folded-back portion (332). The second support section (337) is connected to the first support section (336) at a front thereof.

Description

technical field [0001] The present invention relates to a card edge connector for receiving an end portion of a printed circuit board. Background technique [0002] Conventionally, there is known a card edge connector for connecting a sub-board such as a memory module to a printed circuit board as a mother board built in a device such as a personal computer. For example, Patent Document 1 discloses a card edge connector including an insulating housing mounted on a motherboard, and a pair of locking arms mounted on the housing to hold a sub-board. The lock arm is formed by punching and bending a metal plate, and holds the sub-board by the elasticity of the lock arm itself. [0003] In recent years, initiatives have been made to connect a plurality of daughter boards to a mother board. For example, for the purpose of increasing the memory capacity of a personal computer, a plurality of memory modules are connected to a motherboard. On the other hand, in devices requiring mi...
