Abstract

The present invention relates to a cable assembly for a camera, the cable assembly comprising: pin terminals connected to a cable; and an inner molding part that encloses a portion of the pin terminals therein. The inner molding part includes: a body that forms the exterior and has therein a plurality of through-holes through which a portion of the pin terminals pass; and cutout portions formed in the side wall of the body by cutting both sides of portions in which the through-holes are formed. When the pin terminals pass through the through-holes of the body, the cutout portions move outward and widen the space through which the pin terminals pass. The present invention has the effects of making it easy to assemble a pin connector and increasing the force with which the pin connector is fixed to the cable.

Description

cable assembly for camera

The present invention relates to a cable assembly for a camera, and more particularly, to a camera cable that facilitates assembly of the pin terminal and increases the fixing force of the pin terminal to the cable.

Various electronic devices, such as a camera module, have a structure in which power is supplied from the outside and an electrical signal is received or transmitted to an external control device.

In particular, automotive electronics require an integrated cable assembly to power the camera and transmit multiple signals.

That is, there is a need for a camera cable assembly capable of preventing damage and failure of the camera due to moisture penetration by securing high watertightness while stably maintaining electrical contact for transmitting power and camera signals.

Accordingly, the connector for connecting the various signal lines included in the cable to the electronic device should have less noise generated at the connection portion and there should be no risk of disconnection of each signal line. In addition, when moisture generated inside a cable including a plurality of extensions penetrates into the connection part with the electronic device, corrosion of the connection part may occur. Therefore, a cable connector for connecting a vehicle electronic device that can be easily exposed to temperature changes in an external environment to a cable must have excellent electrical connection reliability and physical fastening force.

In the case of a conventional cable assembly for a camera, an electric wire is inserted into a pin, and a portion protruding from the inside of the pin is electrically connected through contact with the electric wire.

However, in the case of such a structure, when an external force such as bending is applied, contact failure may easily occur.

The present invention has been devised to solve the problems of the prior art, and an object of the present invention is to prevent a contact defect from occurring even with an external force such as bending.

In order to achieve the above object, the cable assembly for a camera of the present invention is characterized in that it consists of a pin terminal connected to the cable, and an inner molding part including a part of the pin terminal therein, wherein the inner molding part forms an outer shape, It consists of a body having a plurality of through holes through which the pin terminal passes therein, and a cutout in which both sides are cut at one side of the through hole through which the pin terminal passes in the body, and the pin terminal passes through the through hole of the body. When the cutout is moved outward, it is characterized in that the space through which the pin terminal is passed is widened.

The pin terminal includes a pin as a contact portion, a protrusion extending to one end of the pin and increasing in width, and a coupling portion coupled to the cable, and when the protrusion of the pin terminal passes through the through hole of the body, the After the cutout of the inner molding part moves outward and a space through which the protrusion can pass is made, when the passage of the cutout is completed, the cutout returns to its original position and the protrusion is fixed in a state where the protrusion passes through the body characterized in that

The through hole has a width sufficient for the cable to pass through, and is narrowed to a size sufficient for the pin to pass through at the lower end.

According to the present invention, a high contact force is provided between a pin terminal and a cable to prevent defects from occurring even in an external force such as bending.

Hereinafter, the present invention will be described in more detail with reference to the accompanying exemplary drawings. In describing the present invention, descriptions of already known functions or configurations will be omitted in order to clarify the gist of the present invention. Also, like reference numerals refer to like elements throughout.

Referring to FIG. 1 , the cable assembly 1 for a camera according to the present invention includes a cable 3 , a pin terminal 20 including a part of the cable 3 therein, and a part of the pin terminal 20 and the cable It consists of an inner molding part 10 including a part of (3) inside, and an external molding part 2 including a part of the pin terminal 20, the inner molding part 10, and the cable 3 therein. .

The cable 3 is composed of an inner wire 4a which is a conductor, an inner shell 4 surrounding the inner wire 4a, and an outer shell 5 surrounding the plurality of inner shells 4 .

The extension line 4a of the cable 3 is located inside the pin terminal 20 and comes into contact with the pin terminal 20 to exchange electrical signals between the cable 3 and the pin terminal 20 .

The inner molding part 10 covers and protects the contact part between the pin terminal 20 and the inner wire 4a, and the outer molding part 2 includes the inner molding part 10, the inner shell 4, and the outer shell 5. It covers and protects part of the

Referring to FIG. 2 , the pin terminal 20 includes a pin 21 as a contact portion, a protrusion 22 connected to one end of the pin 21 , and a coupling portion 22 coupled to the inner line 4a.

After positioning the inner wire 4a on the coupling part 22, both ends of the coupling part are bent in a direction surrounding the inner wire 4a to fix the inner wire 4a inside the coupling part 22 and make electrical connection at the same time. do

As shown in FIG. 3 , a plurality of through holes 13 through which the pin terminal 20 passes are formed in the inner molding part 10 , and the cable 3 is internally molded in a state coupled to the pin terminal 20 . It is fitted into the through hole 13 of the part 10 .

The through hole 13 has a width sufficient for the endothelium 4 to pass through, and then narrows at the bottom to have a size that allows the pin 21 to pass therethrough.

Referring to FIGS. 4 and 5 , the inner molding part 10 includes a body 11 having a plurality of through holes 13 that form an outer shape and through which the pin terminal 20 passes therein, and the body 11 . At one side of the through hole 13 through which the pin terminal 20 passes, both sides are made of a cutout 12 .

That is, the cutout 12 is formed in the outer portion of the body 11 of the portion in which the through hole 13 is formed, and the upper end is connected to the body 11 , and both sides and the lower end are separated.

6 and 7, when the pin terminal 20 is inserted into the through hole 13 from the upper end of the body 11, the pin 21 is discharged to the lower end, and the protrusion 22 is inserted into the body 11 ) when located at the lower end of the cutout 12 moves in the outward direction to form a space through which the protrusion 22 can pass.

After the passage of the protrusion 22 is completed, the cutout 12 moves back to its original position, the width of the through hole 13 becomes narrower again, and one end of the protrusion comes into contact with the end of the cutout 12 so that the pin 21 ) serves to prevent the body 11 from falling upwards from the inside.
