Description

TECHNICAL FIELD [0001] The present invention relates to a time lag fuse for enhancing process efficiency and a method of manufacturing the same,

The present invention relates to a time lag fuse with improved process efficiency and a method of manufacturing the same. More specifically, the present invention relates to a time lag fuse and a method of manufacturing the same, The present invention relates to a time lag fuse and a method of manufacturing the time lag fuse.

The apparatus and the apparatus using electricity are driven by a built-in battery or an external power supply, and when such an apparatus or apparatus is supplied with an overcurrent exceeding the rated current, the overcurrent causes damage to components or malfunction of the apparatus do.

A fuse is an overcurrent protection device for solving such a problem. When a fuse is disposed between an electric source and components of the device and is supplied with an overcurrent equal to or higher than the rated current, the fuse is cut off to prevent circuit damage and malfunction do. That is, the fuse includes an insoluble body having a low melting point, and when the overcurrent flows, the fusible material melts by the heat generated by the current, thereby breaking the converter.

Various studies have been made on fuses due to these advantages. In general, conventional fuses have a disconnection type fuse which is disconnected immediately after overcurrent supply is cut off and the overcurrent is cut off. It is classified as a disconnected time lag fuse.

FIG. 1 is an exploded perspective view showing a time lag fuse disclosed in Korean Patent No. 10-1002868 filed by the applicant of the present invention and registered as a patent ("Spot welding time lag fuse").

The time lag fuse 100 of FIG. 1 includes a pair of current-carrying wires 110 connected to a power source such that a current is passed therethrough, a rectangular fixed body 110 having a current- And a case 140 which covers the upper side of the conductive wire 110 and the usable body 130. The upper case 120 is connected to the upper end of the conductive wire 110 and is shorted when overcurrent flows.

According to the conventional art 100 configured as described above, since the movable body 130 is formed in a straight line shape, the slack of the movable body 130 can be prevented from being slackened even for a long time, thereby enhancing durability.

However, according to the conventional art 100, there are a process operation for processing the electric wires 110 to a predetermined thickness, a process operation for processing the soluble body 130 to a certain thickness and length, 110), it is necessary to separately perform a process operation for completing the process, which is troublesome, and the process time is excessively delayed.

In addition, since the conventional technique 100 has both ends of the fusible body 130 coupled to the electric wire 110 through welding, the process becomes complicated, and the defect rate and manufacturing cost due to the welding process increase.

In addition, the conventional art 100 has a structural limitation in that the resistance value of the soluble body 130 is not constant due to the replenishment used for the welding of the soluble body 130, resulting in a poor accuracy of the product.

In addition, since the resistance value of the movable body 130 is determined by the thickness and the length of the movable body 130, the conventional technique 100 is required to precisely process the movable body 130 with a desired thickness and length, It is necessary to process a precisely dimensioned thickness and length of the movable body 130 having a desired dimension, and at the same time, since the movable body 130 does not have a desired resistance value even with a small dimension difference, The process has complicated limitations.

In other words, it is possible to reduce the manufacturing cost and time by minimizing the manufacturing process, 2) improve the accuracy of the usable body by omitting the welding process, 3) determine the resistance value through the thickness processing of the usable body, Time lag fuse and its manufacturing method which can solve the conventional problems of complicated process are urgently needed.

As shown in FIGS. 2 and 3, the time lag fuse 1, which is an embodiment of the present invention, includes a pair of terminal lines 51 and 51 'and terminal lines 51 and 51' The movable body 53 connecting both ends is manufactured as a unitary body,

A body 2 in which the terminal wires 51 and 51 'of the usable portion 5 are inserted so as to pass therethrough and a body 2 in which a lower portion is opened, And a case 3 covering the body 2 and the usable portion 5 protruding from the body 2. [

In the present invention, for convenience of explanation, the case 3 has been described as being formed into a square pillar shape having a bottom opening, but the shape of the case 3 is not limited thereto, and even if it is formed into a cylindrical shape or a polygonal columnar shape It is acceptable.

The body 2 is formed of a plate material having a thickness and an area, through which the terminal lines 51 and 51 'of the usable portion 5 penetrate. At this time, the body 2 is formed in a shape corresponding to the bottom opening of the case 3.

Further, the lower surface of the body 2 is seated on the electric circuit, and the lower surface of the body 2 is provided with the heat releasing groove 21 from the lower surface to the inside thereof, and the heat releasing groove 21 functions to circulate the heat generated inside.

The body 2 and the usable portion 5 protruding upward from the body 2 are sealed by the case 3. [

The case 3 is formed into a polygonal shape or a cylindrical shape having a bottom opening and a receiving space formed therein and the body 2 is coupled to the bottom opening so that the terminal lines 51, 51 'and the fusible body 53 are accommodated.

At this time, a display unit (not shown) is formed on the upper surface of the case 3 so that the type of the fuse may be displayed in various colors. Since the configuration of the display unit is known from the prior art 100, A description thereof will be omitted.

'자형 형상의 일체형으로 제조된다.4 has a pair of terminal lines 51 and 51 'connected to a power source line so as to allow current to flow, and a pair of terminal lines 51 and 51' connected to the ends of the terminal lines 51 and 51 ' The terminal wires 51 and 51 'and the allowable body 53 are connected to each other by a conductive member 53, which is made of a conductive material,

Shaped " shape.

At this time, the terminal wires 51 and 51 'and the fusible element 53 are integrally formed by a press process, so that a process operation of conventionally machining the terminal wires and a process of machining the fusible element into a predetermined thickness and length And the process of joining the both ends of the fusible body to each of the terminal wires through welding are separately separated so that the process is complicated and the resistance value is not maintained constant by the replenishment during welding, Can be solved dramatically.

In addition, the soluble body 53 is formed to have a thickness of approximately 0.2 to 0.3 and has a predetermined desired resistance characteristic, and is melted when it is in an abnormal state to cut off the converter. At this time, the abnormal state is defined as a state in which an over-power higher than the rated power is supplied.

In addition, the fusible element 53 has a plurality of perforations 531 penetrating both surfaces thereof on both sides thereof. At this time, since the number of the perforations 531 is proportional to the resistance of the solenoid 53, the solenoid 53 increases in resistance due to the formation of the perforations 531 to have a predetermined resistance value. That is, the fusible element 53 is formed of the same conductive material as the terminal wires 51 and 51 ', and has a low resistance. However, the resistance increases due to the punctures 531, so that a desired resistance characteristic is obtained.

The shape of the perforations 531 is not limited, and may be formed in a circular or polygonal shape.

In addition, the fuse 53 can be stably used for a long time by forming a coating portion (not shown) coated on the outer surface with tin to prevent deformation by the coating portion and improving the strength.

In addition, since the soluble body 53 is formed in a straight line shape, when the soluble body is conventionally formed in a coil shape, the coil can be prevented from being sagged and thus can be stably used for a long time.

The terminal lines 51 and 51 'are formed of a conductive material having a predetermined length and a small thickness, and one end is connected to the power line and the other end is connected to the solenoid 53.

One end portion of the terminal wires 51 and 51 'connected to the power line is protruded downward from the body 2 and the other end portion connected to the solenoid body 53 protrudes upward from the body 2 ). At this time, the region protruding upward from the body 2 is sealed by the case 3 like the solenoid 53.

When the terminal lines 51 and 51 'of the time lag fuse 1 are connected to the power source line, the current supplied through the terminal line of the time lag fuse 1 is applied to the terminal (53) to the other terminal line. At this time, if voltage and current of abnormal state are supplied to one terminal line, heat is generated by the resistance of the solenoid 53, so that the solenoid 53 is heated, whereby the solenoid 53 melts, It is possible to prevent damage and malfunction of the circuit due to the abnormal state.
