2 to 4, a coaxial cable tuning apparatus 100 according to an embodiment of the present invention includes a tub 110 storing liquid-like lead, And a discharge unit 120 disposed at a predetermined distance from the upper part of the tub 110 to discharge the liquid lead transferred by the pump P to the tub 110, ).

The heat sink 110 forms a predetermined space in which a liquid lead (hereinafter, referred to as 'lead') can be stored. When the lead heating device H is heated by heating the lead or maintaining the temperature of the lead, Respectively.

The pump P serves to transport the lead stored in the lead 110 and can be received in a casing 130 provided on one side of the lead 110 in the longitudinal direction. For the reference, the pump P may be a known pump device using a motor and an impeller, and various other pump devices used in general industrial fields may be used.

An inlet 131 connected to the space formed in the tub 110 is provided at a lower end of the casing 130 and a discharge port 132 through which a lead transported by the pump P is discharged Lt; / RTI >

The discharge unit 120 receives the discharge of the discharge from the discharge port 132 of the casing 130 and discharges the discharge to the discharge vessel 110. The discharge discharged from the discharge unit 120 discharges in two directions So that the core wire 1a of the coaxial cable 1 and the shield 1c can be covered with a predetermined time difference.

The discharging unit 120 includes a receiving member 121 receiving a delivery conveyed by the pump P and a first discharging opening 122 and a second discharging opening 122 provided on the bottom surface of the receiving member 121, 123).

The support member 121 may be detachably coupled to the discharge port 132 by forming a predetermined space portion capable of receiving a discharge discharged from the discharge port 132 of the casing 130.

The supporting member 121 may be detachably coupled to the discharging port 132 of the casing 130, and various known configurations may be applied. For example, a guide rail 133 having a U-shaped cross section into which the longitudinal end of the receiving member 121 can be inserted is installed on the inner surface of the casing 130 partitioning the discharge port 132 So that the longitudinal end of the receiving member 121 is detachably coupled to the outlet 132 of the casing 130.

4, the first discharge port 122 and the second discharge port 123 are arranged in the longitudinal direction (the direction of the arrow X shown in FIG. 2) and the widthwise direction of the receiving member 121 In the direction of the arrow Y shown in FIG. 5A).

The lead introduced into the receiving member 121 through the discharge port 132 of the casing 130 is discharged to the tub 110 through the first discharge port 122 and the second discharge port 123, .

4, the first discharge port 122 and the second discharge port 123 are spaced apart from each other by a predetermined distance along the longitudinal direction and the width direction of the receiving member 121, As shown in FIG.

The reason why the first discharge port 122 and the second discharge port 123 are spaced apart from each other by a predetermined distance along the width direction of the receiving member 121 is that the shield 1b of the coaxial cable 1 In order to cover the core wire 1a of the coaxial cable 1 with the lead after it is coated with preference. That is, the shield 1b and the core wire 1a of the coaxial cable 1 are sequentially coated with lead.

The reason why the first discharge port 122 and the second discharge port 123 are spaced from each other by a predetermined distance along the longitudinal direction of the receiving member 21 is that the core wire 1a of the coaxial cable 1, The insulator 1c disposed between the insulators 1b is prevented from being coated with lead. That is, the first discharge port 122 and the second discharge port 123 are spaced apart from each other by a distance occupied by the insulator 1c of the coaxial cable 1 to discharge the lead only to the formation portions of the core wire 1a and the shield 1b To do.

2, the coaxial cable 1 is disposed in a direction parallel to the longitudinal direction of the receiving member 121, and then the space formed between the receiving tubular member 110 and the receiving member 121 The shield 1b of the coaxial cable 1 can be primarily covered by the lead discharged from the second discharge port 123. [

Then, the core wire 1a of the coaxial cable 1 can be secondarily covered by the lead discharged from the first discharge port 122. [

The coaxial cable 1 and the shield 1b of the coaxial cable 1 can be coated with a lead in a single process of passing the end of the coaxial cable 1 under the receiving member 121 have.

For reference, in order that the core wire 1a having a circular cross section and the entire periphery of the shield 1b (the entire circumferential edge) are covered uniformly, the first discharge port 122 or the second discharge port 122 shown in FIG. Is preferably 8 to 12 times larger than the circumferential length of the core wire 1a or the shield 1b of the coaxial cable 1 to be coated. This is because the length L1 of the first discharge port 122 or the discharge length L2 of the second discharge port 123 is set to be longer than the length L1 of the second discharge port 123 when the time for the core wire 1a or the shield 1b to pass through the lead- , L2) of the coaxial cable 1 to be coated is preferably 8 to 12 times larger than the circumferential length of the core wire 1a or the shield 1b of the coaxial cable 1 to be coated. Particularly, in consideration of the mass production speed, It is most preferable to form it to have a size of approximately 10 times as viewed. That is, when the length L1 of the first discharge port 122 or the length L2 of the second discharge port 123 is less than 8 times the peripheral length of the core wire 1a or the shield 1b, ) Or the shield 1b is hard to be covered with the lead, and when it exceeds 12 times, the working time becomes too long and the desired mass production rate can not be maintained.

For example, when the length of the core wire 1a of the coaxial cable 1 is 1.57 mm, the width L1 of the first discharge port 122 should be about 15.7 mm. Can be uniformly coated. If the length of the circumference of the shield 1b of the coaxial cable 1 is 9.42 mm, the length L2 in the width direction of the second discharge port 123 should be about 94.2 mm, The lead can be uniformly coated.

5 and 6, the discharging unit 110 may control the area of the first discharging opening 122 or the second discharging opening 123 formed in the receiving member 121 (140). ≪ / RTI >

Accordingly, the moving lid 143b can be moved in the direction in which the fixed lid 143b is disposed or in the opposite direction in a state where the moving lid 143b is seated in the seating groove 145. [

For example, when the length of the core wire 1a of the coaxial cable 1 to be coated is longer than the length of the core wire 1a of the coaxial cable 1 which is conventionally used in the coating process, the area of the first discharge port 122 The moving lid 143b which has been blocking the moving lid 143b is moved in the opposite direction in which the fixed lid 143a is disposed to increase the separation distance between the fixed lid 143a and the moving lid 143b. The area of the first discharge port 122 that is blocked by the fixed lid 143a and the movable lid 143b can be further opened to correspond to the length of the extended core wire 1a.

When the length of the shield 1b of the coaxial cable 1 to be coated is smaller than the length of the shield 1b of the coaxial cable 1 which is conventionally used in the coating process, the area of the second discharge port 123 The moving lid 143b which has been blocking the moving lid 143b can be moved in the direction in which the fixed lid 143b is disposed to reduce the distance between the fixed lid 143a and the moving lid 143b.
