As shown in these figures, the appearance and skeleton of the connector 10 are formed by the housing body 20. The housing body 20 is formed in a substantially hexahedral shape by injection molding a synthetic resin material that is an insulator.

Through holes 22 are formed in the housing body 20 to penetrate to both sides. The through part 22 is a space in which the terminal 30 to be described later is inserted and seated, and is formed by the number corresponding to the number of terminals 30.

Although not shown, a lance is formed inside the through hole 22 so as to be fixed by hanging the terminal 30. The lance, which is elastically deformable due to the properties of the material and the shape, is fixed to the terminal 30, thereby preventing the terminal 30 from being separated from the connector housing.

A fixing part 24 is formed on the outer surface of the housing body 20. The fixing part 24 is a portion corresponding to the rotating shaft 52 which will be described later, and allows the rotating shaft 52 to be rotatable about the fixing part 24. That is, the fixing part 24 is coupled to the rotation shaft 52 to form a hinge, so that the rear holder 40, which will be described later, before the terminal 30 is inserted into the housing body 20, the housing body 20 To remain combined with the.

This is to prevent the rear holder 40 from rotating when the rear holder 40 is not easily separated from the outer surface of the housing main body 20, that is, during the packaging and conveying process of the connector housing.

As shown in FIG. 5, a terminal 30 is inserted into the connector housing. The terminal 30 is made by processing a highly conductive metal material by a progressive mold. The terminal 30 is inserted into the through part 22 and fixed by being walked by the lance.

The barrel part 32 is formed in the terminal 30. The barrel 32 compresses the insulation of the wire 34 to be described later, so that the terminal 30 and the wire 34 can be firmly coupled. At this time, the diameter of the barrel portion 32 is formed larger than the distance between the support jaw 48 to be described later so that the terminal 30 can be supported by the rear holder 40 to be described later.

A wire 34 is connected to the terminal 30. The wire 34 serves to electrically connect between the terminal 30 and other components separated by a predetermined distance or more. The wire 34 having a constant diameter extends rearward of the connector housing through the interference avoiding portion 44 which will be described later.

The rear holder 40 is coupled to the housing body 20. The rear holder 40 supports the terminal 30 so that the terminal 30 can be firmly fixed to the housing body 20. More precisely, the rear holder 40 supports the barrel portion 32 as shown in FIG. 5 to prevent the terminal 30 from coming off the rear of the connector housing when viewed with reference to the drawings. .

As shown in Figure 4, the skeleton of the rear holder 40 is formed by a body portion (42). The body portion 42 is substantially rectangular when viewed from the front side, and has a shape corresponding to one surface of the housing body 20 in the direction in which the terminal 30 is inserted. The rear holder 40 is made of a synthetic resin material similar to the housing body 20.

An interference avoiding portion 44 is formed at the center of the body portion 42. The interference avoiding portion 44 is formed in a substantially U shape, thereby allowing the wire 34 to extend rearward. Therefore, the width of the interference avoiding portion 44 is formed to correspond to the diameter of the wire 34.

Hook hooks 46 are formed at both ends of the body portion 42. The hook hook 46 has a shape corresponding to the hook jaw 28, and is formed to be elastically deformable due to its material and shape. That is, the hook hook 46 is coupled to the hook jaw 28 through the elastic deformation is formed in the center thereof, so that the rear holder 40 can be coupled to the housing body 20. Preferably, the hook hook 46 may be formed to protrude toward the hook jaw 28 so that the hook hook 46 may be easily coupled to the hook hook 28.

A support jaw 48 for supporting and fixing the terminal 30 protrudes from the body portion 42. The support jaw 48 is formed to protrude toward the through-hole 22 adjacent to the interference avoiding portion 44, thereby supporting the barrel 32.

Preferably, the support jaw 48 is formed to protrude toward the through-hole 22 in pairs on both sides of the interference avoiding portion 44. This is to support the barrel portion 32 from both sides, so that the terminal 30 is more firmly fixed to the housing body 20. At this time, the width between the support jaw 48 is formed smaller than the diameter of the barrel portion (32). This is to prevent the rear end of the barrel portion 32 from being supported between the support jaw 48 so that the terminal 30 is separated from the housing body 20. Of course, the width between the supporting jaw 48 should be equal to or larger than the diameter of the wire 34 so that the wire 34 can pass therethrough.

As a result, assuming that the diameter of the barrel portion, the diameter of the wire 34, and the width between the support jaw 48 are D1, D2, and D3, respectively, the relationship D2 ≦ D3 <D1 is the same.

Coupling grooves 49 are formed in the body portion 42. The coupling groove 49 is coupled to the coupling protrusion 29 so that the rear holder 40 can be fixed to one surface of the housing body 20. That is, the defect holder 29 formed on the outer surface of the housing main body 20 to which the rear holder 40 is rotated to be contacted is inserted into the coupling groove 49, so that the rear holder 40 has a housing main body ( 20) may be fixed to one surface. This is to prevent the insertion work of the terminal 30 is prevented by the rear holder 40 by fixing the rear holder 40 before the terminal 30 is inserted into the housing body 20.

The connecting portion 50 is formed at one end of the body portion 42. The connecting portion 50 is formed extending from both sides of one end of the body portion 42, and serves to connect the rotating shaft 52 to be described later and the body portion 42.

A rotation shaft 52 is formed between the connection parts 50. The rotating shaft 52 formed in the shape of a bar is connected to the fixing part 24, so that the rear holder 40 can rotate about the fixing part 24. That is, the rotation shaft 52 is inserted into the channel 25, so that the rear holder 40 is rotated about the channel 25 to be fastened or separated from the housing body 20. It is composed. At this time, the body portion 42, the connecting portion 50 and the rotating shaft 52 is formed integrally.

Hereinafter, the operation of the connector housing according to the present invention having the configuration as described above in detail.

8A and 8B show a state in which the connector housing according to the present invention is assembled. According to this, the terminal 30 is mounted in the housing body 20 constituting the present invention. That is, the terminal 30 is inserted into and fixed to the through part 22.

At this time, as shown in Figure 8a, prior to inserting the terminal 30, the rear holder 40 is maintained in a state fixed to the housing body (20). That is, the rear holder 40 is fixed to the bottom surface of the housing main body 20 when the coupling protrusion 29 is inserted into and coupled to the coupling groove 49. Through this, since unwanted rotation of the rear holder 40 is prevented from occurring, the operator can easily insert the terminal 30.

In the process of inserting the terminal 30 into the through-hole 22, the terminal 30 is in contact with the lance. At this time, if the terminal 30 is pushed further while overcoming the elastic force of the lance, the terminal 30 is inserted while elastically deforming the lance. In addition, when the terminal 30 is completely inserted, the lance is restored again to hang one side of the terminal 30, thereby preventing the terminal 30 from being separated from the housing body 20 by an external force.

In this state, the rear holder 40 fixed to the outer surface of the housing main body 20 by the coupling groove 49 and the coupling protrusion 29 is pulled outward. That is, the rear holder 40 is pulled and rotated in a direction away from the outer surface of the housing main body 20 so that the fixing of the rear holder 40 can be released. In this case, since the rear holder 40 is connected to the housing main body 20 before the terminal 30 is installed, the operator does not need to separately prepare the rear holder 40.

Next, the rear holder 40 is continuously rotated around the channel 25 to couple the rear holder 40 to the open side of the through hole 22 into which the terminal 30 is inserted. At this time, the rear holder 40 is inserted so that the wire 34 is inserted through the open side of the interference avoiding portion 44 so that the rotation of the rear holder 40 is not prevented by the wire 34. Rotate That is, as shown in FIG. 6, the wire 34 is positioned between the interference avoiding portions 44.

When the rear holder 40 is further rotated in this state, the hook hook 46 is coupled to the hook jaw 28. In this process, the hook hook 46 is elastically deformed by the hook jaw 28, and when the rear holder 40 is pushed further while overcoming such elastic force, the hook hook 28 is attached to the hook hook 46. Is inserted. When the hook hook 46 and the fastening groove are completely coupled, the hook hook 46 is restored again so that the rear holder 40 and the housing body 20 are firmly coupled. That is, the housing body 20 and the rear holder 40 are assembled by only rotating the rear holder 40 without the process of matching the direction of the rear holder 40 with the direction of the housing body 20. Work becomes easy.

In this process, the support jaw 48 is in contact with the rear of the barrel portion (32). At this time, since the distance between the support jaw 48 is smaller than the diameter of the barrel 32, the barrel 32 is not separated through the interference avoiding portion 44, the support jaw 48 Is supported by. Therefore, even if an external force acts on the wire 34 or deformation occurs in the lance, the terminal 30 may be fixed to the housing body 20 by the rear holder 40.

The process of separating the terminal 30 from the housing body 20 proceeds in the reverse order of the assembly process. That is, after releasing the coupling of the hook hook 46 and the hook jaw 28, the rear holder 40 is rotated to couple the coupling groove 49 and the coupling protrusion 29 to the rear holder 40. To be fixed to an outer surface of the housing body 20. Then, the terminal 30 is pulled apart in the direction opposite to the inserted direction while pressing the lance using a jig (not shown).

The rear holder 40 is always kept in a fixed state so as to be rotatable with the housing body 20 in the above-described coupling process and separation process. Therefore, the rear holder 40 does not need to be prepared or classified separately from the housing body 20.

The rights of the present invention are not limited to the embodiments described above, but are defined by the claims, and various changes and modifications can be made by those skilled in the art within the scope of the claims. It is self-evident.

For example, the hook hook 46 may be formed in the housing body 20, and the hook jaw 28 may be formed in the rear holder 40. In addition, the coupling groove 49 and the coupling protrusion 29 may also be formed in the housing body 20 and the hooking jaw 28, respectively. In addition, the rear holder 40 may be fixed to the outer surface other than the bottom of the housing body 20 to be rotatable.

In the connector housing according to the present invention as described in detail above, the following effects can be obtained.

First, in the present invention, since the rear holder is kept connected to the housing body, there is no need to store or transport the rear holder separately from the housing body, thereby increasing the efficiency of logistics and material management.

In addition, before the terminal is inserted into the housing body, the rear holder is held in the state of being coupled to the housing body by the coupling groove and the engaging protrusion, so that the unwanted rotation of the rear holder or the fastening with the housing body can be prevented. have.

In addition, in the present invention, since the rear holder is rotatably connected to the housing main body by the fixing part and the rotating shaft, the operator can accurately fasten the housing to the housing main body by simply rotating the rear holder, thereby improving workability.
