Problems solved by technology

[0005] As a result, the connector shell may be deformed due to heat when the contacts are reflow assembled on the printed circuit board
When the deformation of the connector shell is large, it is impossible to connect the connector plug to the input and output ports of the computer, etc.

Embodiment approach 1

[0041] First, the structure of the connector 11 to which the auxiliary member for connectors according to Embodiment 1 of the present invention is applied is as follows: figure 1 and figure 2 give. The connector 11 includes a connector housing 12 and a plurality of contacts 13 held by the connector housing 12 .

[0042] The overall shape of the connector housing 12 is substantially a cube having a central axis Z1, and an opening 14 is formed along the entire width at the front end side in the direction of the central axis Z1. The opening 14 is used to fit the mating connector, and has a depth approximately half of the length of the connector housing 12 along the central axis Z1. Due to the presence of the opening 14, as figure 2 As shown in (C), the connector housing 12 is substantially U-shaped when viewed from the side.

[0043] On the rear end side of the upper surface 12a of the connector housing 12, a pair of stepped portions 15 arranged in the width direction are ...

Embodiment approach 2

[0073] Figure 14 give Figure 1 ~ Figure 3 The connector 11 is shown in a state where the auxiliary connector 51 according to Embodiment 2 is attached. In Embodiment 1, the auxiliary member 21 for a connector can be attached to the connector 11 or 41 not only at the time of assembling but also at the time of boxing. In contrast, the auxiliary member 51 for a connector according to Embodiment 2 is attached to the connector 11 only at the time of assembly.

[0074] This connector auxiliary member 51 has a base portion 52 having a flat plate shape, a wall portion 53 rises from one end of the base portion 52, and a wiring board support portion 54 is formed on the other end side.

[0075] A protruding portion 55 is formed at the central portion of the wall portion 53, and the protruding portion 55 protrudes on the surface facing the direction of the circuit board support portion 54 in parallel with the base portion 52. Resist surface 56 . In addition, the thickness D2 of the p...

Abstract

An auxiliary part for connectors is connected to the connectors. The connectors has a connector house with an opening part used for inserting mating connectors, and contact terminals held on the connector house, wherein each contacting part of the contact terminal formed by one end of the contact terminal is arranged in the opening part, and meanwhile, the other end of the contact terminal protruded from the connector house is formed with a contact connecting part. The auxiliary part for the connectors has a protrusion part with a thickness substantially equal to the height of the opening part. When the protrusion part is inserted into the opening part, the contact connecting part is assembled on a printed circuit board in a reflux way.

Description

technical field [0001] The present invention relates to an auxiliary material for a connector, and particularly relates to an auxiliary material for a connector which is mounted on a connector and used when the connector is reflow-assembled on a printed wiring board (printed wiring board). Background technique [0002] In the past, for electronic circuits such as computers, external devices were connected to the provided input and output ports through connector plugs and cables. However, in recent years, the development of In the interface technology, by setting the necessary interface (interface) in the connector plug, various external devices can be directly connected to one input and output port for use. [0003] Inside the connector plug, contacts for connecting input and output ports are connected to interface circuits and cables through printed circuit boards. Therefore, it is necessary to assemble the contacts to the printed wiring board, for example, by reflow solde...
