【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a plan view of an electric connector structure according to the present invention, and FIG. 2 is a bottom view of the same.

The electrical connector structure according to the present invention comprises a connector housing 1 and terminals 2 and 3 attached to the connector housing 1 as shown in FIGS.

That is, as shown in FIGS. 6 to 10, the connector housing 1 has a plug insertion recess 4 at one end thereof and left and right terminal lead-out grooves 5 and 6 at the other end thereof. The lead-out grooves 5 and 6 are arranged in the middle of the lead-out grooves with a partition wall 7a interposed therebetween. Terminal press-fitting holes 7 and 8 are formed from the left and right terminal lead-out grooves 5 and 6 to the bottom surface 4a of the plug insertion recess 4.

As shown in FIGS. 11 and 12, the left terminal 2 includes a press-fitting portion 9 and a connecting leg portion 10. The connecting leg portion 10 is bent at a right angle to the press-fitting portion 9, The tip side of the part is the contact part 11. A resistor holding piece 12 is provided at the base of the connecting leg portion 10. The resistor holding piece 12 is bent in two steps, and a V-shaped holding groove 13 is formed at its tip. is there. Further, on the outer peripheral surface of the connector housing 1, there are formed ridges 14 along the axis of the connector housing 1 on the front, rear, left and right sides, and the end faces of these ridges 14 are in the same plane.

As shown in FIGS. 13 and 14, the right terminal 3 has a left-right symmetrical shape with respect to the left terminal 2, and a portion of this terminal 3 corresponding to each portion of the left terminal 2 is formed. Is indicated by adding a ′ to the reference numeral of each part of the left terminal 2.

Then, the left terminal 2 is press-fitted into the left terminal press-fitting hole 7 of the connector housing 1 and the right terminal 3 is press-fitted into the right terminal press-fitting hole 8 from the terminal lead-out grooves 5 and 6, respectively. The terminals 2 and 3 are assembled to the connector housing 1. In this case, the contact portions 11 and 11 'of the left and right terminals 2 and 3 project into the plug insertion recess 4 of the connector housing 1, and the connecting leg portions 10 and 10' of the left and right terminals 2 and 3 are connected to the terminal lead-out groove. 5 and 6, respectively, and the end portions of the connecting leg portions 10 and 10 'project outward from the mouth portions 5a and 6a of the terminal lead-out grooves 5 and 6, respectively. The resistor holding pieces 12, 12 'of the left and right terminals 2, 3 face each other.

The electrical connector thus configured is attached to the mounting panel 15 by abutting the end surface of the ridge 14 to the mounting panel 15.

When connecting this electric connector to an electric circuit, the contact is made in the state where the contact is made in the holding grooves 13, 13 ′ of the resistor holding pieces 12, 12 ′ of the left and right terminals 2, 3. By laser welding to the holding pieces 12 and 12 ', the antibody 16 is laid across the resistor holding pieces 12 and 12'.

According to the above-described embodiment, the resistor 16 can be directly connected to the terminals 2 and 3, and the connection circuit of the resistor 16 can be removed from the circuit board, and the configuration of the circuit board can be simplified. Can be converted. Moreover, since the resistor 16 is connected to the resistor holding pieces 12 and 12 'of the terminals 2 and 3, the resistor 16 can be laser-welded.

[0017]

[Effect of the device]

 As described above, in the electrical connector structure according to the present invention, the contact of the resistor is fixed to the connecting leg portion of the pair of terminals provided in the connector housing, which protrudes outside the connector housing, and the resistor is laterally held. Since the resistor holding piece to be formed is formed, the resistor can be directly connected to the terminal, the connecting circuit of the resistor can be removed from the circuit board, and the configuration of the circuit board can be simplified. Moreover, since the resistor is connected to the resistor holding piece of the terminal, it becomes possible to have a monitoring circuit through this resistor.
