L'invention concerne une transition (1) entre un contact central (2) d'un composant coaxial (10), et une ligne de transmission (30) d'un circuit (3, 3', 3"), notamment radiofréquence (RF), le contact central comprenant une partie avant cylindrique (23) et une partie arrière (21), dans le prolongement de sa partie avant, en contact et fixée à la ligne de transmission par une brasure (B), la partie arrière (21) comprenant au moins un évidement de matière (22), délimitant un volume formant une réserve pour la brasure (RB).
摘要:
Erstens wird durch eine geeignete Formgebung erreicht: - dass sich die Flussmittelgase nicht zwischen dem Verbindungselement und dem metallischen Substrat ansammeln und sich dadurch die Haftung des Verbindungselements auf dem substrat verringert. - dass die effektive benetzbare Lötfläche bei gleich bleibender Grundfläche vergrößert wird und sich somit die Haftung des Verbindungselements auf dem Substrat erhöht. - dass die funktionell nicht notwendige Masse des Verbindungselements eliminiert wird, um die für die Lötung notwendige thermische Energie zu reduzieren und folglich kalte Lötstellen zu vermeiden. Zweitens wird durch Verwendung von Verankerungen die Haftung des Verbindungselements auf dem Substrat verbessert, so dass in Folge die mechanische Belastbarkeit bezüglich Dreh- und Kippmoment erhöht wird.

Provided is a surface-mount type electric connecting terminal which is disposed between opposing conductive objects (including for example a conductive pattern 12 on a PCB 10) and is configured to electrically connect the objects while easily adjusting pressing force and recovery force. The electric connecting terminal includes a cylindrical fixed member 410 which is made from a metallic material; a cylindrical movable member 420 which is slidably inserted in the fixed member and is made from a metallic material; and an electrical conductive spring 430 which is accommodated in the fixed member and whose one end contacts with the bottom of the fixed member and the other end contacts with the bottom of the movable member for thereby allowing the movable member to elastically slide against the fixed member. The fixed member comprises a hook portion to prevent the movable member from being disengaged from the fixed member when elastic recovery force is transferred from the spring. A flat surface is formed in an upper end surface of the movable member for the sake of vacuum pickup, and a lower end surface of the fixed member is configured to be reflow-soldered using solder cream 14.

An electrical connector (1) for connecting a flat conductive member (P) includes a housing (10) made of an electrical insulating material and including a terminal holding groove (13,14), and a terminal (20,30) held in the terminal holding groove for contacting with the flat conductive member. The terminal holding groove (13,14) includes a first groove portion (A,A') and a second groove portion (B,B'). The first groove portion (A,A') has a first groove width (d1), and the second groove portion (B,B') has a second groove (d2) width smaller than the first groove width (d1). The terminal (20,30) includes an upper arm portion (21,31), a lower arm portion (22,32) extending in parallel with the upper arm portion, and a combining portion (23,33) combining the upper arm portion (21,31) and the lower arm portions (22,32). The lower arm portion (22,32) includes a connecting portion (22D,32B) accommodated in the first groove portion (A,A') and to be soldered to a circuit board. The upper arm portion (21,31) includes a pressing portion (21B-1,31B-1) for pressing the flat conductive member (P).
