A pressure port 340 is formed to pressurize and support the outer surface.

One end of the pressure port 340 is connected to the inner circumferential surface of the cutting hole 330, and the opposite free end is bent inclined to the coupling space to press the outer surface of the housing 100.

In addition, a pair of insertion grooves 120 are further concavely formed at the upper left and right sides of the housing 100 such that the free ends of the pressing holes 340 are correspondingly inserted as shown in FIG. 3.

For example, after the rear end of the housing 100 is inserted into the coupling space 301 of the fixed frame 200, the free end of the pressing holes 340 is bent into the coupling space 301 to be inserted into the insertion groove 120. Can be inserted into each field.

In addition, a pair of fixing pins 350 integrally formed at the lower left and right sides of the fixing frame 300 protrude downward, and the pinholes 11 are inserted into the upper surfaces of the substrate 10 to correspond to the fixing pins 350. ) Is formed up and down.

Here, the lower ends of the fixing pins 350 may have a tapered shape in which the front and rear widths thereof gradually decrease toward the lower side so as to be easily inserted through the upper end of the pinhole 11.

The fixing pins 350 may be positioned in the left and right directions of the fixing frame 300 based on the terminal passage groove 390 to be described later, as shown in FIG. 4.

That is, since the pressing hole 340 of the fixed frame 300 is positioned in the insertion groove 120 of the housing 100, the housing 100 is firmly fixed to the fixed frame 300 without being moved in the front-back direction by an external force. Can be fixed.

And, since the pressing hole 340 and the fixing pin 350 is formed integrally by cutting a portion of the fixing frame 300, it can provide a firm coupling force without increasing the number of parts of the device.

In addition, a terminal through-groove 390 penetrates up and down on a lower surface of the fixing frame 300 so that rear ends of the connection terminals 200 protrude downward.

That is, by forming the terminal through groove 390 on the lower surface of the fixed frame 300, it is possible to secure the connection space between the rear terminal of the lower terminal 210 and the upper terminal 220 and the substrate 10.

The front support part 320 extends forward from the front end of the body 310 positioned below the housing 100, and has a lower end of the front support part 320 coupled to the upper surface of the substrate 10. Support 310 from the front.

The insertion protrusions 360 may cut the front and rear portions of the front support portion 320 in the left and right directions, and may bend and deform a portion of the front support portion 320 downward based on the cut line of the front and rear portions.

At this time, the lower surface of the insertion protrusions 360 is formed to protrude downward while forming a curvature in the left and right direction, the lower surface of the insertion protrusions 360 has a form that gradually decreases as the left and right widths go downward.

For example, when the insertion protrusions 360 are vertically inserted into the protrusion holes 12, the front and rear surfaces of the insertion protrusions 360 are locked perpendicularly to the protrusion holes 12.

The insertion protrusions 360 are positioned in front of the fixing pin 350 described above, and the insertion protrusions 360 are respectively positioned in the left and right directions with respect to the center of the front support part 320.

In addition, the fixed frame 300 may be bent vertically downward from both ends of the left and right in the upper portion of the housing 100, then bent horizontally to the lower surface of the housing 100 may be coupled to each other male and female.

Here, the support protrusion 321 is preferably disposed in the left and right directions with respect to the center of the front support portion 320, respectively, the position of the support protrusion 321 can be applied in various ways as needed.

Therefore, the support protrusion 321 supports the front support part 320 at the same height as the rear end of the connection terminal 200 protruding to a predetermined length to the lower portion of the housing 100, so that the housing 100 and the front support part are flat. Can be located.

Meanwhile, the insulating layer 500 may be further coupled to the inside of the housing 100, and the insulating layer 500 may be manufactured to a predetermined width using an insulating material.

In this case, insert molding the lower terminal 210 and the middle plate 400 to integrally form the insulating layer 500, and insulated from the integrated lower terminal 210 and the middle plate 400 After placing the upper terminal 220 on top of the layer 500 assembly, a method of forming the housing 100 outside may be used.

As a result, the present invention forms the front support part 320 at the front end of the fixed frame 300 located below the housing 100, thereby preventing the fixed frame 300 from being forwardly forwarded by the load biased forward. It can prevent.

In addition, the present invention can be combined with the fixing frame 300 and the housing 100 and the substrate 10 without the need for a separate fastening member, so the number of parts is not large, so that the manufacturing cost can be reduced, and the fixing pin 350 and the insert can be used. Coupling force may be improved through the double coupling structure of the protrusion 360.

In addition, according to the present invention, since the carrier cutout 420 connected to the middle plate 400 protrudes out of the housing 100 after completion of the housing 100, the carrier 20 may be easily removed after the molding is completed.
