Rather, these embodiments are presented so that this disclosure will be thorough and complete, and the scope of the invention will be fully conveyed to those skilled in the art. In these illustrations, for the sake of illustration True, the shape of these components is magnified.

A detection unit is a disposable consumable measurement sensor that is immersed in a molten metal during the manufacture of an iron or non-ferrous metal to measure the state information of the metal and discarded after use. The detecting unit measures the state information of the molten metal, such as the temperature and the amount of oxygen, so the molten metal is controlled according to heat and the molten metal component is confirmed, or the molten metal component is analyzed.

1 is a cross-sectional view of a detecting device in accordance with an embodiment of the present invention.

As shown in Fig. 1, a detecting device has a structure in which a bracket unit 2 is coupled to a spray gun 3 which is operated automatically or manually, and a detecting unit 6 is mounted on the bracket unit 2. A connector unit 1 is electrically and mechanically coupled to the detector unit 6 to the bracket unit 2, and is disposed between the detecting unit 6 for a measuring device and the bracket unit 2 for supporting the detecting unit 6. A compensation line 7 is connected to the detecting unit 6 at one end, and the other end is connected to the analyzing device through the bracket unit 2 and the connector unit 1 (for example, a converter 4 or an indicator recorder in FIG. 1) 5).

The detecting unit 6 may include a sensing component (refer to numeral 410 of FIG. 8) (eg, a temperature measuring sensor and an oxygen measuring sensor) and a sampling component that the molten metal can be filled (refer to FIG. 8 Figure 420). The detecting unit 6 may measure the state information of the molten metal or fill the molten metal to the sampling in such a manner that it is immersed in the molten metal and maintained for a few seconds to rise again.

The status information converted by the converter 4 is transmitted to a worker through the indication recorder 5.

Figure 2 is a perspective view showing a state in which the connector of Figure 1 is separated and joined.

A connector unit 1 is a related art of the outer connector 11 and the inner connector 12 in a female/female shape.

The outer connector 11 includes a hollow outer connector body 110 having an inner space and a front end of the bracket connecting member 112 coupled to the outer connector body 110, and disposed parallel to a longitudinal direction of the outer connector body 110. And having a hollow portion in communication with the inner space of the outer connector body 110. The outer connector body 110 is disposed coaxially with the bracket coupling member 112. Here, the outer connector body 110 has an outer diameter larger than the bracket connecting member 112. A cut-off member 114 extends from a front end of the bracket coupling member 112 to define the front end of the bracket coupling member 112 as a plurality of portions defined in the bracket coupling member 112. The number of the shutoff members 114 is determined by the compensation line 7. Moreover, the number of compensation lines 7 is determined by the number of sensing components (refer to numeral 410 of FIG. 8). Here, as depicted in FIG. 2, the cutoff members 114 may differ in length from each other.

Similarly, a compensation wire fixing surface 116 is recessed from an outer surface of the bracket coupling member 112 and disposed at a rear end of each of the cutting members 114. The compensation line 7 is drawn out through the cutting member 114 and bent to be seated and fixed to the compensation line fixing surface 116. At least one compensation line securing surface 116 may be provided depending on the number of the detecting devices (or the number of sensors that are mounted on the sensing component 410). The compensation line fixing surface 116 is disposed at the rear end of the cutting member 114. As described above, since the cutting members 114 have different lengths from each other, the compensation line fixing surfaces 116 may be disposed at different positions from each other along a longitudinal direction of the bracket coupling member 112.

An inner connector 12 includes an inner connector body 120 and an inner connector insertion member 122. The inner connector body 120 is inserted into the inner space of the outer connector 11. The inner connector insertion member 122 is coupled to a front end of the inner connector body 120 and is disposed parallel to a longitudinal direction of the inner connector body 120. The inner connector insertion member 122 is inserted into the bracket connecting member A hollow portion of 112. The inner connector body 120 is disposed coaxially with the inner connector insertion member 122. Here, the inner connector body 120 has an outer diameter that is larger than the inner connector insertion member 122. A compensation wire insertion slot 124 is recessed from an outer surface of the inner connector insertion member 122, defined on the outer surface of the inner connector insertion member 122. The compensation line insertion slot 124 may define the longitudinal direction of the bracket coupling member 112. The inner connector insertion member 122 has a cross-shaped cross section. In a state where the inner connector insertion member 122 is inserted into the bracket coupling member 112, the compensation wire insertion slot 124 is defined to correspond to the blocking member 114. The inner connector body 120 includes a stop plate 128 disposed on a front end thereof. The stop plate 128 has a compensation wire insertion hole 126. The inner connector insertion member 122 is inserted into the compensation wire insertion hole 126. Here, the compensation wire insertion hole 126 is divided by the inner connector insertion member 122 into the same number as the compensation wire insertion slots 124. The compensation wire insertion slot 124 communicates with the interior of the inner connector body 120 through the compensation wire insertion hole 126.

The compensation wire 7 passes through the inner connector body 120 through the compensation wire insertion hole 126 and is seated in the compensation wire insertion slot 124. The compensation line 7 is seated on the connector unit 1. The connector unit 1 has one end fixed to the compensation line fixing surface 116 in a bent state, and the other end is coupled to the detecting unit 6. The bracket unit 2 includes a joint terminal corresponding to one end of the compensation line 7 fixed to the compensation line fixing surface 116. Here, the joint terminal may be joined to the compensation line 7 fixed to the compensation line fixing surface 116.

Figure 3 is a photograph depicting a modified example of an outer connector of Figure 2.

A method of fixing the connector unit to the compensation line 7 according to the related art will be described below. The compensation wire 7 is inserted into the inner connector body 120 through the compensation wire insertion hole 126, and then placed on the compensation wire insertion slot 124. When the compensation line 7 is continuously inserted, a front end of the compensation line 7 completely penetrates the front end of the bracket coupling member 112 to connect the bracket from the bracket. The front end of 112 extends. Then, the compensation wire 7 is bent through the cutting member 114 to the outer connector body 110 and placed on the compensation wire fixing surface 116. One end of the compensation line 7 is fixed to the compensation line fixing surface 116, and an excess compensation line 7 is cut to allow the compensation line 7 to be seated corresponding to the compensation line fixing surface 116.

A worker pulls the compensation wire 7 from the inner connector body 120 toward the rear side to stably fix the compensation wire 7 (in particular, the bent portion of the compensation wire 7) to the compensation wire fixing surface 116. Since the compensation line 7 is pulled out from the inner connector body 120 in a state where the compensation line 7 is fixed to the compensation line fixing surface 116, an external force is applied from the compensation line fixing surface 116 to the outer connector body 110 to the bracket. The connecting member 112.

Here, since at least one of the cut-off members 114 is defined in the bracket connecting member 112, the front end of the bracket connecting member 112 may be outwardly deployed by the external force from the compensating line fixing surface 116 to the bracket connecting member 112.

Similarly, since the compensation wire 7 is fixed between the inner connector insertion member 122 and the bracket coupling member 112 in a state where the inner connector insertion member 122 is inserted into the bracket coupling member 112, an external force acts outward to The bracket connects an inner surface of the member 112. Therefore, the bracket coupling member 112 may be deployed due to the shape and structure.

The damage of the bracket connecting member 112 may interfere with the degree of adhesion of the connector unit 1 to the bracket unit 2. Since one end of the compensation line 7 is fixed to the compensation line fixing surface 116 and is not tightly connected to the connection terminal of the bracket unit 2, the status information measured by the detection unit 6 and one output from the indication recorder 5 An error will occur between the measured values. When an error occurs in the status information, a metal commodity may be produced that is different from the expected quality. Similarly, since the detecting unit is repeatedly immersed in the molten metal to measure the state of the molten metal, the detecting sheet Yuan may be wasted.

Similarly, when the compensation line 7 is placed on the connector unit 1, the compensation line 7 is exposed to the outside of the outer connector 11 only when the compensation line 7 completely penetrates the front end of the bracket coupling member 112. Therefore, the compensation line 7 must be unnecessarily inserted into the bracket coupling member 112 to cut off the excess compensation line. Therefore, the compensation line 7 may be wasted. As a result, the cost of measuring the status information using the detecting device may increase.

4(a), 4(b), 4(c), 4(d), 4(e) are a left side view, a front view, a rear view, a cross-sectional view and a right side view, respectively, which are described in accordance with the present invention.

The bracket connecting member 210 is connected in parallel to the outer connector body 200 and has a hollow portion 216 that communicates with the inner space 202.

Although each of the outer connector body 200 and the bracket coupling member 210 has a cylindrical shape in FIGS. 4(a) to 4(e), the present invention is not limited thereto. For example, each of the outer connector body 200 and the bracket connecting member 210 may have a tube shape.

A compensation wire fixing surface 214 is recessed from an outer surface of the bracket coupling member 210 and disposed on the outer surface of the bracket coupling member 210. A cutoff member 212 extends from the compensating line securing surface 214 to the outer connector body 200 in a reverse direction to divide the bracket joining member 210 into a plurality of portions. A compensation line 40 extends through the hollow portion 216 of the bracket coupling member 210 to the cutting member 212 and is fixed to the compensation wire fixing surface 214.

The compensation line 40 is used in a number of connector units 50, possibly depending on the use The detection unit 6 measures the type and quantity of the sensor. Although the four cutoff members 212 are defined as the same angle θ1 in FIGS. 4(a) to 4(e), the present invention is not limited thereto. Likewise, depending on the number of detectors used in the compensation line 40, at least one compensation line securing surface 214 may be provided. The shutoff member 212 may correspond to the compensation line securing surface 214.

The bracket coupling member 210 may further include a cap-shaped fixing member 220 that connects the front ends of the bracket coupling members 210 to each other. Since the fixing member 220 is coupled to the front end of the bracket coupling member 210, it may prevent the front ends of the bracket coupling members 210 from being unfolded. Therefore, according to the related art, the unfolding phenomenon of the connector unit 1 may be improved to closely connect one end of the compensation wire 40 to a joint terminal of the bracket unit 2.

The outer connector 20 may further include a stopper 230 protruding from a front end surface of the outer connector body 200 and an outer annular surface of the bracket coupling member 210. Although the three stoppers are set to the same angle θ2 in the description of FIG. 4, the present invention is not limited thereto. The stopper 230 restricts insertion of the connector unit 50 into an insertion position of the bracket unit 2 to prevent the connector unit 50 from being inserted beyond.

5(a), 5(b), 5(c), 5(d) are left side view, front view, rear view and right side view, respectively, which illustrate one embodiment according to another embodiment of the present invention. Connector.

An inner connector 30 includes an inner connector body 300 that is inserted into an inner space 202, and an inner connector insertion member 310 that is connected in parallel to the inner connector body 300 and inserted into the hollow portion 216.

Although each of the inner connector body 300 and the inner connector insertion member 310 has a cylindrical shape in FIGS. 5(a) to 5(d), the present invention is not limited thereto. For example, each of the inner connector body 300 and the inner connector insertion member 310 may have a tube shape.

A compensation wire insertion slot 312 is recessed from an outer surface of the inner connector insertion member 310 in a longitudinal direction defined by an outer surface of the inner connector insertion member 310. The inner connector body 300 includes a blocking plate 304 disposed at a front end thereof. The blocking plate 304 has a compensation wire insertion hole 302. The inner connector insertion member 310 is disposed at the compensation wire insertion hole 302. Here, the compensation wire insertion hole 302 may be divided by the inner connector insertion member 310 into the same number as the compensation wire insertion slot 312. The compensation wire insertion slot 312 communicates with the inside of the inner connector body 300 through the compensation wire insertion hole 302.

6(a), 6(b) are a front view and a perspective view, respectively, which illustrate an inner connector in accordance with another embodiment of the present invention.

An inner connector insertion member 310 has a reference surface 314 and a ramp 330. The reference surface 314 may be defined as a bottom portion of the compensation insertion slot 312. The two reference surfaces 314 depicted in Figure 6 are adjacent and perpendicular to each other. The compensation line 40 is seated on the two reference surfaces 314. The reference surfaces 314 may be disposed at the same distance from a central axis of the inner connector insertion member 310. The ramp 330 projects from each reference surface 314. Here, a distance from the central axis of the inner connector insertion member 310 to the slope may increase toward a front end of the inner connector insertion member 310. The compensation line 40 moves through the compensation line insertion hole 302 toward the reference surface 314. Then, the compensation line 40 is guided to the cut-off member 212 along the slope and is easily exposed to the outside of the bracket joint member 210. Therefore, unlike the method in which the compensation line 7 is excessively inserted and thus exposed to the front end of the bracket coupling member 112, it is not necessary to cut the compensation line 40. Therefore, the waste of the compensation line 40 may be minimized. The ramp 330 may be disposed at different locations along the longitudinal direction of the inner connector insertion member 310.

Figure 7 is a perspective view showing a process of joining a connector of Figures 4 and 5.

The connector unit 50 has a structure in which the inner connector 30 is inserted into the outer connector 20. The outer connector 20 may include the fixing member 220. The compensation wire 40 is seated in the compensation wire insertion slot 312 through the compensation wire insertion hole 302 through the inner connector body 300.

Likewise, the inner connector 30 may have a length l ₂ that reduces a distance l _{3 of} the securing member 220 from a distance l _{1 of} the outer connector 20. When the inner connector 30 is inserted into the outer connector 20, the front end of the inner connector insertion member 310 contacts the fixing member 220. Therefore, the inner connector 30 is seamlessly engaged with the inside of the outer connector 20 of the connector unit 50.

4 and 5, at least one inner stop surface 301 has a planar shape that may be defined on the outer surface of the inner connector body 300, and an outer stop surface 204 has a shape corresponding to the inner connector body 300. The outer stop surface 204 is disposed on an inner surface of the outer connector body 200. When the inner connector 30 is coupled to the outer connector 20, the inner and outer stop surfaces 301 and 204 are engaged to face each other, thereby preventing the inner connector 30 from rotating.

As depicted in FIG. 4, an orientation indicating component 201 may be disposed on the outer surface of the outer connector body 200 and parallel to the outer stop surface 204. This result indicates a combined position of the connector unit 50 when the connector unit 50 is coupled to the bracket unit 2.

Figure 8 is a cross-sectional view of the detecting device of Figures 4 and 5 including the connector.

The detecting unit 6 is coupled to one end of the connector unit 50. The detecting unit 6 includes the sensing component 410 and the sampling component 420. When the sensing component 410 is immersed in the molten metal, the sensing component 410 may measure the state information as a temperature or amount of oxygen of the molten metal. Here, the molten metal is filled in the sampling member 420. The sampling component 420 will later be separated and destroyed. The filled molten metal may be used to analyze the composition as it is. The other end of the connector unit 50 is coupled to the bracket unit 2. Since the connector unit 50 of the detecting device in FIG. Including the fixing member 220, it is possible to prevent damage of the bracket coupling member 210. Similarly, since the connector unit 50 of the detecting device includes the slope 330 in FIG. 8, the compensation line 40 may be easily coupled to the connector unit 50. As such, it is possible to prevent waste of the compensation line 40.

According to these embodiments of the invention, the connector unit and the detection device comprising the connector unit are affected as follows.

The detecting device includes the fixing member, and the fixing member has the front end slits that are coupled to the bracket connecting member in a cap shape to prevent the bracket connecting member from unfolding.

Since the unfolding of the bracket coupling member has been avoided, the compensation wire fixed to the compensation wire fixing member may be accurately coupled to the joint terminal connected to the bracket. Therefore, errors in the status information measured and transmitted from the detecting unit may be reduced.

The compensation groove can be easily placed on the compensation wire fixing member through the insertion groove of the bracket coupling member.

Although the invention has been described in detail with reference to exemplary embodiments thereof, the invention may be embodied in many different forms. Therefore, the technical concept and scope under the patent scope are not limited to the selected embodiment.
