Description

Plug connector structure of plug-in terminal block

The invention relates to a plug connector structure of a plug-in terminal, in particular to a plug connector structure which has excellent binding elasticity and structural strengthening effect to ensure that the mutually inserted terminals are optimally engaged and conductive.

At present, the plug-in type terminal block structure is similar to the utility model patent of the Chinese Patent Publication No. CN 201112705Y "plug-in terminal block", which mainly includes: a column type plug terminal (metal plug terminal) and a column type jack. a member (a metal connecting jack member) having a through hole for receiving the column type plug terminal, and the column type jack member is provided with at least one slot along a direction of the outer side wall thereof, The through hole has an outward expandability, and the outer side wall of the middle portion of the column type jack member is provided with an annular recessed portion, and the annular recessed portion is sleeved on the outer peripheral side of the spring steel sleeve. The spring elasticity of the spring steel sleeve enables the through hole portion to have sufficient elastic tightening force and structural strength to ensure that the cylindrical jack member can tightly cover the column type plug terminal for a long time.

In addition, there is a utility model patent of the "terminal structure of a power connector" of the Chinese Patent Publication No. CN 201038406Y, which mainly comprises: a female terminal for electrically plugging a male terminal, the female terminal being composed of a body and an outer casing The body is provided with a positioning portion that can be fixed in the preset insulating seat body, and a welding portion that can be worn outside the preset insulating seat body is provided on one side of the positioning portion, and the butt portion is disposed on the other side away from the welded portion. The abutting portion has at least one axially extending slot, and a ring groove is disposed on the outer periphery of the abutting portion, the ring groove is adapted to fit an outer casing, and a limit is provided on one end side of the outer casing The limiting portion can be embedded in the slot and formed into a card to prevent axial rotation of the outer casing on the surface of the ring groove, and at the same time, the outer casing can be elastically deformed and expanded outward by the outer casing. Moreover, the outward extension of the butt joint can be restricted to achieve the effect of being surely positioned and electrically connected.

However, the above various structures are arranged such that an annular recessed portion (ring groove) is provided on the outer peripheral side of the middle portion of the column type jack member (or the female terminal) for accommodating a spring steel sleeve (outer casing) On the outer periphery; as a result, there are the following shortcomings in practical applications:

1. 由於該柱型插孔件（或母端子）於中段外周側設置一環狀凹陷部份（或環槽），因此會造成該柱型插孔件（或母端子）形狀與結構變得較複雜，增加成型與加工的困難度，進而使生產成本的上昇，缺乏價格上之競爭力。
2. 由於設計時必須確保該彈簧鋼套或外殼體內周緣與該環狀凹陷部份或環槽外周緣尺寸之適當配合，否則會有套合後不密合而造成夾持力不足（彈簧鋼套或外殼體內周緣尺寸過大），或該柱型插孔件、母端子之彈性擴張不足（彈簧鋼套或外殼體內周緣尺寸過小）之情形，此種尺寸精密度之要求亦會造成生產成本之增加。
3. 由於該彈簧鋼套（或外殼體）係為一具有部份缺口之Ｃ形斷面結構，且其組裝時係直接以該缺口套合於該環狀凹陷部份（或環槽）上，此種組裝方式，若使該彈簧鋼套（或外殼體）本身具有較小之結構強度，則可較容易將該彈簧鋼套（或外殼體）予以擴張，再越過該具有較大外徑之柱型插孔件（或母端子）外側，以組裝於該環狀凹陷部份（或環槽）上，但如此之彈簧鋼套（或外殼體）之彈性必然較差，較容易因而降低其對該柱型插孔件（或母端子）之束緊力；反之若該彈簧鋼套（或外殼體）本身具有較大之結構強度，則該彈簧鋼套（或外殼體）雖然具有較佳之結構彈性，但將因此不易組裝於該環狀凹陷部份（或環槽）上，如此一來，在結構設計的考量上，將形成組裝難易度及束緊功效上之取捨二難。

　　有鑑於習見之插接端子結構有上述缺點，發明人乃針對該些缺點研究改進之道，終於有本發明產生。
