Description

電連接器 Electrical connector

本發明公開一種電連接器，尤其涉及一種電連接器的焊接固定結構。 The invention discloses an electrical connector, in particular to a soldering and fixing structure of an electrical connector.

通用串列匯流排(Universal Serial Bus,USB)介面作為一種標準的輸入/輸出介面，已被廣泛應用於眾多電子設備的設計中。在個人電腦、手機、數碼相機、音樂播放器等電子產品領域。由於產品形狀或成本等原因的限制，大多移動設備中均採用微型USB結構。中華民國專利新型第M331826號揭示這這樣一種電連接器，其包括遮蔽殼體，絕緣本體及設置於絕緣本體上的端子，遮蔽殼體設有4個焊接至電路板的固定片，焊接後遮蔽殼體底部與電路板之間留有一定高度的空隙。 The Universal Serial Bus (USB) interface is a standard input/output interface that has been widely used in the design of many electronic devices. In the field of electronic products such as personal computers, mobile phones, digital cameras, music players. Micro USB structures are used in most mobile devices due to limitations in product shape or cost. An electric connector of the present invention includes a shielding case, an insulative housing and a terminal disposed on the insulative housing. The shielding housing is provided with four fixing pieces welded to the circuit board, and is shielded after soldering. A certain height gap is left between the bottom of the housing and the circuit board.

然，在使用過程中反復插拔USB連接設備是不可避免的，為了與對接連接器可靠連接，兩個連接器之間的配合力較大，所需插拔力量也較大，又遮蔽殼體底部留有空隙，僅靠四個單薄的固定片與電路板連接很容易因外力過大而導致固定片鬆動，進而導致外力直接作用於端子與電路板的固持臂，極易造成端子與電路板脫焊引起接觸不良，不符合現代產品的使用要求。 However, it is inevitable to repeatedly plug and unplug the USB connection device during use. In order to reliably connect with the docking connector, the mating force between the two connectors is large, and the required plugging force is also large, and the housing is shielded. There is a gap at the bottom, and only four thin fixing pieces are connected to the circuit board. It is easy to loosen the fixing piece due to excessive external force, which causes the external force to directly act on the holding arm of the terminal and the circuit board, which is easy to cause the terminal and the circuit board to be off. Welding causes poor contact and does not meet the requirements of modern products.

鑒於此，實有必要提供一種改進之電連接器，以克服上述電連接器存在之缺陷。 In view of this, it is necessary to provide an improved electrical connector that overcomes the deficiencies of the electrical connectors described above.

與先前技術相比，本發明電連接器至少具有以下優點：固持部、固持臂和固定片可同時焊接在電路板上，而固持部的焊接面積大，保證了電連接器能夠穩定可靠地焊接在電路板上，避免因多次插拔而脫焊，導致使電連接器接觸不良，影響產品使用。 Compared with the prior art, the electrical connector of the present invention has at least the following advantages: the holding portion, the holding arm and the fixing piece can be welded on the circuit board at the same time, and the welding area of the holding portion is large, thereby ensuring stable and reliable welding of the electrical connector. On the circuit board, avoid de-soldering due to multiple plugging and unplugging, resulting in poor contact of the electrical connector and affecting product use.
