Problems solved by technology

[0007] However, since the crimping blade does not temporarily hold the covered wire, the covering layer will be peeled off by cutting into it, so there is a concern that the wire (core wire) will be damaged, and when this peeling is not performed reliably, there will be a gap provided at the base of the crimping blade. Defects in which soldering of contact protrusions and conductors becomes poor

Embodiment 1

[0054] figure 1 The connector of Embodiment 1 of the present invention is shown in , the connector main body 1 is formed of an insulating material such as resin, the recess 2 of the long groove is formed on the front thereof, and on the opposite side of the recess 2 of the rear face 1a, A plate-shaped tail block portion 3 is integrally protruded from the middle portion in the width direction, and a stepped portion 4 is formed by the rear surface 1 a of the connector body 1 and the upper surface 3 a of the tail block portion 3 .

[0055] In the connector main body 1 , predetermined intervals are maintained in the longitudinal direction of the concave portion 2 , and only intermediate portions of the plurality of contacts 5 which are metal plate pieces are embedded. The front side portion 5a of the tail portion 5 of each contact is accommodated in the recess 2, and the tail portion 5b of each contact 5 protrudes (exposes) from the rear face 1a of the connector main body 1 along ...

Embodiment 2

[0063] Such as Figure 4 As shown, embodiment 2 is different from embodiment 1 only in the U-shaped clamping part at the rear end of each contact, a U-shaped cutout 7 is formed at the top part of the tail part 5b of the contact 5, and this part is bent upward into an inverted V shape, A U-shaped clamping portion 8 is formed. The inverted V-shaped U-shaped clamping portion 8 bent like this, because its half portion 8c extends obliquely upward from the horizontal tail portion 5b, and its other half portion 8d further obliquely extends downward, so as Figure 5 As shown, the temporary holding of the covering portion 10a of the cable 10 becomes easy.

Embodiment 3

[0065] Embodiment 3 is also different from Embodiment 1 only in the U-shaped clamping portion at the rear end of each contact. That is, in Embodiment 1, the top end of the tail portion 5b with the U-shaped notch 7 is bent upward to approximately a right angle, and the U-shaped clamping portion 8 is erected at an approximately right angle at the rear end of the upper surface 3a of the tail platform portion 3, but In embodiment 3, such as Figure 6 As shown, because the top end of the tail portion 5b with the U-shaped notch 7 is not bent, it still extends from the rear end of the upper part 3a of the tail platform part 3, beyond the U-shaped clamping part that extends all the way from the rear end of the upper part 3a of the tail platform part 3 8, so it is easier to form the tail portion 5b of the contact 5 than Embodiment 1 and Embodiment 2.

[0066] Such as Figure 7 As shown, in order to connect the cables to the contacts 5 of the connector of the third embodiment, the cov...

Abstract

The present invention provides a cable soldering type connector which can easily temporarily hold a sheathing portion of a cable in a state which can be kept as it is, and which can reliably and uniformly perform soldering of a core wire and a tail portion of a contact, and , During this soldering, the contact part of the contact is not affected by the solder. A tail platform (3) protrudes from the back of the connector body (1), and the tails (5b) of each contact point (5) protrude from the back of the connector body along the top of the tail platform and are supported on it. On the tail part of each contact, a soldering hole (9) is formed on the tail platform part, and a U-shaped clamping part (8) for clamping the covering part of the cable is formed at the rear end of the tail part.

Description

technical field [0001] The present invention relates to a cable soldering type connector (connector) that temporarily holds a sheathing portion of a cable and solders a core wire to a contact. Background technique [0002] Patent Document 1 (Kokai Publication No. Hei 5-6708) discloses that a U-contact portion and a punched portion for soldering are formed on a crimping terminal block embedded in a printed circuit board. In the normal use state where the terminal block is connected to the electrical component, the lead terminal of the electrical component is pressed into the U contact part, and when harsh conditions such as vibration and impact are applied, the lead terminal is inserted into the punching hole for soldering The part is a crimping terminal block for soldering. [0003] This is to use separately the U-contact portion of the terminal block for crimping and the punched portion for soldering according to the conditions, not to use both of them at the same time. ...
