Abstract

A pull-type tripping device for an electrical connector has a housing unit and a connector body unit. The connector body unit is disposed inside the housing unit, the connector body unit has a board body and a frame body vertically coupled to each other, a plurality of contact terminals are formed inside the frame body, and each upper portion of two sides of the frame body is formed a hook opening thereon. The pull-type tripping device includes a snap hook unit and a pull belt. The snap hook unit includes a fix arm, a flexible arm, and two snap hook arms. Each of the snap hook arms is disposed inside the frame body, and each of the two snap hook arms is removably buckled at the hook opening.

Claims

1. A pull-type tripping device with an electrical connector, the electrical connector comprises a housing unit and a connector body unit, the housing unit having a rear housing and a front housing oppositely coupled to the rear housing, the rear housing having a first opening slit, the connector body unit disposed inside the housing unit, the connector body unit having a board body and a frame body vertically coupled to the board body, a plurality of contact terminals inside the frame body, and a hook opening formed on each upper portion of two sides of the frame body, wherein the pull-type tripping device further comprises:

a snap hook unit having;

a fix arm spanned and fixed on a top surface of the board body;

a flexible arm disposed consecutively at a front end of the fix arm and extended along two sides of the fix arm; and

two snap hook arms respectively disposed at two outer ends of the flexible arm and extended downwards and forwards, wherein each of the two snap hook arms has a snap hook, each of the two snap hook arms is disposed inside the frame body, and each of the snap hooks is removably buckled with the hook opening; and

a pull belt having a first end and a second end opposite to the first end, wherein the first end is fixed to the front housing, the second end spanned over a top surface of the flexible arm and passed through the first opening slit, and a position of the second end of the pull belt on the top surface of the flexible arm is higher than a fixed point position for fixing the first end of the pull belt to the front housing.

2. The pull-type tripping device for the electrical connector of claim 1, wherein an upper portion of the front housing has a frame opening, and the front housing has an outer frame body, and an inner frame body is disposed at the upper portion of the front housing, the inner frame body is placed between the outer frame body and the frame opening, and a second opening slit is formed between the inner frame body and the outer frame body, the first end of the pull belt passes through the second opening slit and the frame opening to be fastened to the inner frame body.

3. The pull-type tripping device for the electrical connector of claim 2, wherein the frame body of the connector body unit protrudes outward through the frame opening of the front housing.
