Description

Right angle terminal for high voltage and its assembly method {Right angle connector for high voltage and assembling method thereof}

The present invention relates to a high-voltage light-angle terminal, and more particularly, to an assembly structure of a'a' shaped high-voltage terminal composed of a plurality of parts.

In general, the connector is composed of a connector housing and a terminal, and is widely used in power circuits such as washing machines, refrigerators, and automobiles. The use of connectors in these electrical and electronic devices has the advantage of greatly simplifying the maintenance work as well as the manufacturing of the device, since several parts can be assembled individually and then inserted into the final product.

Recently, with the advent of electric vehicles, a connector capable of allowing high voltage has been developed. Among the high voltage terminals, there is a light angle terminal. The right angle terminal is a connector shaped like an'a', and it can be seen that the direction of the part coupled with the mating connector is bent at a right angle.

The high-voltage light-angle terminal is composed of a number of parts. First of all, since it is a'a' shape, at least two terminals extending in an orthogonal direction are required, and a separate housing for protecting each terminal and an outer casing are included. Because of the large number of parts, the assembly order of parts is very complicated. In particular, due to the characteristics of the light angle, the assembling direction is made in at least two directions, and thus, there is a problem in that the operator must accurately understand the assembling direction of each component.

In addition, the high-voltage light-angle terminal must prevent electric shock during use due to its high voltage characteristics. To this end, a component for finger safety is also added so that the operator's finger does not touch it. Therefore, there is a disadvantage that the number of parts is increased and the number of assembly steps is added.

In addition, the high-angle light-angle terminal has at least two terminals extending in an orthogonal direction to each other. Since the installation directions of the two terminals are different, it is important to securely assemble them therebetween. However, in the conventional high-angle light-angle terminal, there is a problem that the contact stability is poor because a play exists between the two terminals. Of course, it is possible to make the assembly part tight to eliminate the clearance, but in this case, when the two terminals are assembled, the insertion force increases, resulting in a problem of poor assembly.

The present invention relates to a high-voltage light angle terminal and its assembly method. The high-voltage light-angle terminal of the present invention (hereinafter referred to as'light-angle terminal') is installed in an electric vehicle or the like and serves to connect between high-voltage components. For example, the present invention can be used to charge the battery inside the electric vehicle. Although the name of the present invention is a right angle terminal, it can also be viewed as a kind of connector.

As shown in Figure 1, the light-angle terminal of the present invention is approximately'ㄱ' shaped. This means that the connection direction of the vertical terminal 73 and the extension wire 70 connected to one side and the mating connector (not shown) are orthogonal to each other. For convenience of description, the direction in which the mating connector is coupled and the horizontal inner connectors 40 and 50 to be described later are inserted is referred to as a first direction (see arrows ① in FIG. 2), and vertical inner connectors 30 and 70. The insertion direction is referred to as a second direction (see arrow ② in FIG. 2).

The exterior of the light-angle terminal of the present invention is made by the outer case (10). In this embodiment, the outer case 10 is made of metal and is made of a die casting method. The case body 11 of the outer case 10 is shaped like a letter'A', and the inside space is shaped like a letter'A'. The case body 11 has two insertion portions, which are the first insertion portion 13 extending in the first direction and the second insertion portion 12 extending in the second direction. Horizontal inner connectors 40 and 50 are inserted into the first insert 13, and vertical inner connectors 30 and 70 are inserted into the second insert 12.

Referring to FIG. 2, there is a coupling stopper 14 inside the first insert 13 in the case body 11. The coupling stopper 14 is made around the inside of the first insertion portion 13 and has a shape protruding in the first direction. The coupling stopper 14 is fitted into the coupling groove 65 (see FIG. 3) of the front holder 60 to be described below, so that the front holder 60 is fixed inside the first insertion portion 13.

The case body 11 has a holder fastening hole 15. The holder fastening holes 15 are made in pairs on the inner left and right sides of the first insert 13, and are located adjacent to the engaging stopper 14. The holder fastening hole 15 is a part where the fastening hook 63 of the front holder 60 is applied, and allows the front holder 60 to be assembled to the case body 11.

Inside the case body 11, a portion extending from the first inserting portion 13 and a portion extending from the second inserting portion 12 meet in the connection space S. Referring to Figure 3, the connection space (S) is made inside the case body 11, where the horizontal terminal 50 and the vertical terminal 73 are assembled and electrically connected to each other. Referring to FIG. 7, it can be said that the connection space S is a space open in both the first direction and the second direction.

The inner connector module 20 is inserted into the case body 11. Here, the inner connector module 20 includes horizontal inner connectors 40 and 50 and vertical inner connectors 30 and 70, and the horizontal inner connectors 40 and 50 and the vertical inner connectors 30 and 70 are external. After being assembled, it is not accommodated in the outer case 10, but is inserted into the outer case 10, respectively, and assembled in the inner space of the outer case 10. 4 to 6 show the inner connector module 20 only, omitting the outer case 10 for ease of understanding.

The horizontal inner connectors 40 and 50 constituting the inner connector module 20 are accommodated in the outer case 10 in the first direction. The horizontal inner connectors 40 and 50 are inserted into the outer case 10 in a first direction, and the horizontal terminal 50 is accommodated therein, and the horizontal terminal 50 is placed in the horizontal inner connectors 40 and 50. It is inserted into the outer case 10 together in a stored state. The horizontal housing 40 constituting the horizontal inner connectors 40 and 50 is made of an insulating material, and the horizontal terminal 50 inserted therein is made of metal.

The horizontal housing 40 is penetrated in the front-rear direction, that is, in the first direction, one side is opened toward the opposite terminal, and the other side is opened inside the outer space of the outer case 10 so that the horizontal terminal 50 can be inserted. have. The horizontal housing 40 has a front protrusion 42 at the front of the housing body 41, and a step surface 42 ′ is provided at the boundary between the front protrusion 42 and the housing body 41. The front holder 60 to be described below fixes the horizontal inner connectors 40 and 50 to the outer case 10 by pressing the step surface 42'.

The front portion of the horizontal terminal 50 is located at the entrance of the front protrusion 42 of the horizontal housing 40. The front portion of the horizontal terminal 50 is opened through the entrance, and the front portion of the horizontal terminal 50 is exposed. However, as shown in FIG. 4, the horizontal terminal 50 is hung on the edge of the entrance and is located inside the interior space of the horizontal housing 40. The horizontal terminal 50 is caught at the entrance edge of the first space 43 of the horizontal housing 40 to prevent separation in the first direction.

At this time, the horizontal terminal 50 is positioned at a predetermined distance from the entrance edge of the first space 43. In addition, since the diameter of the entrance is smaller than the thickness of the operator's finger, it is possible to prevent the operator's finger from accidentally touching the horizontal terminal 50 and electric shock. Thus, the horizontal terminal 50 is spaced apart from the inlet of the first space 43 can be made more reliably through the inner surface structure of the inlet of the horizontal housing 40. Referring to FIG. 3, a spacer 49 protrudes in a first direction at an entrance edge of the first space 43. The spacer 49 spaces the end of the horizontal terminal 50 in a direction away from the entrance edge. Therefore, even if a separate safety device (finger safety) is not provided, the possibility of the operator's finger touching the horizontal terminal 50 is further reduced.

3 and 6, the horizontal housing 40 has a first assembly groove 45 and a second assembly groove 47'. The first assembly groove 45 is a kind of long groove made in the circumferential direction on the rear edge of the horizontal housing 40, where the first assembly rib 35 of the vertical inner connectors 30 and 70 is fitted. And the second assembly groove (47') is made in the protruding end (47) below the vertical housing (30), the second assembly groove (47') is the second assembly rib of the vertical inner connector (30,70) 37 is inserted. As described above, the horizontal housing 40 has a structure for assembling with the vertical inner connectors 30 and 70, so that the inner connector modules 20 can be assembled to each other in the correct position and direction without twisting each other.

The horizontal terminal 50 is accommodated inside the horizontal housing 40. The horizontal terminal 50 serves as an electrical connection function, and is connected to a counter terminal (not shown) and a vertical terminal 73 to be described below, respectively, to electrically connect the counter terminal and the vertical terminal 73. Connect it. Looking at the structure of the horizontal terminal 50, a substantially cylindrical horizontal terminal body 51 forms a skeleton, and there is a first contact portion and a second contact portion at both ends thereof.

The first contact portion and the second contact portion are orthogonal to each other, and the end portion of the counter terminal is inserted in the first direction in the first contact portion, and the end of the vertical terminal 73 in the second direction in the second contact portion. The part is inserted. In this embodiment, the first contact portion is exposed to the front of the entrance of the horizontal housing 40, whereas the vertical inner connectors 30 and 70 are projected to the rear of the vertical housing 30 and exposed to the outside.

Specifically, the first contact portion is made by inserting the first contact spring 53 into the first storage groove 52a made in the first direction. In addition, the second contact portion 55 is made by inserting the second contact spring 55 into the second storage groove 52b made in the second direction. Here, the first contact spring 53 and the second contact spring 55 are intended to increase elasticity when combined with the mating terminal and the vertical terminal 73, and are made of a metal material capable of elastic deformation. The first contact spring 53 and the second contact spring 55 are housed together in the housing body 41 while being inserted into the horizontal terminal 50.

The horizontal inner connectors 40 and 50 include a front holder 60. The front holder 60 is assembled in the first direction to the outer case 10 with the horizontal housing 40 interposed therebetween to fix the horizontal housing 40. 1 and 2, the front holder 60 is located at the entrance side of the outer case 10. The front holder 60 is preferably made of an insulating material. A waterproof seal 69 is positioned between the front holder 60 and the outer case 10 to be compressed in the assembly process of the front holder 60.

Looking at the structure of the front holder 60, there are a total of two holder holes 62 in the holder body 61 of the front holder 60, the relative terminal may enter through the holder hole 62. Of course, the number may vary depending on the number of horizontal terminals 50. There are fastening hooks 63 on both sides of the front holder 60, and the fastening hooks 63 are caught by the holder fastening holes 15 of the outer case 10 through elastic deformation. Reference numeral 67 is an interlock means for transmitting a coupling signal with a mating connector, and 68 is a grounding means for grounding.

Next, when the vertical inner connectors 30 and 70 are described, the vertical inner connectors 30 and 70 are inserted into the outer case 10 in the second direction and coupled with the horizontal terminal 50 inserted first to be electrically connected. The vertical terminal 73 connected to is accommodated therein. The vertical inner connectors 30 and 70, like the horizontal inner connectors 40 and 50, have a vertical housing 30 made of an insulating material to make a skeleton, and a highly conductive vertical terminal 73 is accommodated therein.

In the vertical housing 30 of the vertical inner connectors 30 and 70, the vertical housing body 31 having a substantially hexahedral shape makes its skeleton, and the vertical housing body 31 penetrates in the vertical direction, so that the second space 32 This is made, the vertical terminal 73 is accommodated there. In the vertical housing 30, there is a seating space 33 extending from the end of the second space 32, wherein a part of the horizontal terminal 50 of the horizontal inner connectors 40 and 50 is the second space. It is seated to block (32). The seating space 33 is wrapped with a support panel 34, which will be described below.

The vertical housing 30 has a support panel 34. The support panel 34 protrudes in the second direction upward from the vertical housing 30 and surrounds the seating space 33. A circular support rib 36 protrudes toward the horizontal terminal 50 on the support panel 34. The support rib 36 supports the end portion of the horizontal terminal 50 in a first direction. Therefore, the horizontal terminal 50 can be stably maintained in place without being pushed in the first direction.

The support panel 34 has a first assembly rib 35. The first assembly rib 35 protrudes from the support panel 34 toward the horizontal housing 40, and is substantially circular. The first assembly rib 35 is inserted into the first assembly groove 45 of the horizontal housing 40 so that the horizontal inner connectors 40 and 50 and the vertical inner connectors 30 and 70 are correctly assembled. In addition, a second assembly rib 37 protrudes toward the horizontal housing 40 in the vertical housing 30, and the second assembly rib 37 is located at the bottom side of the seating space 33. The second assembly rib 37 is engaged with the second assembly groove 47' of the horizontal housing 40 to accurately assemble the position and posture of the horizontal inner connectors 40 and 50 and the vertical inner connectors 30 and 70. .

At this time, the first assembly rib 35 and the second assembly rib 37 have different left and right positions along the first direction, and different heights along the second direction. Referring to Figure 2, the first assembly rib 35 is behind the second assembly rib 37 along the first direction, and at the same time, upwards along the second direction. As such, since the positions of the first assembly rib 35 and the second assembly rib 37 are different, the assembly of the horizontal inner connectors 40 and 50 and the vertical inner connectors 30 and 70 can be accurately performed at various positions.

In addition, when the first assembly rib 35 and the second assembly rib 37 are fitted into the first assembly groove 45 and the second assembly groove 47', respectively, the horizontal inner connectors 40 and 50 and the vertical inner connector Since the (30,70) are fixed by interlocking with each other, it is possible to prevent the vertical inner connectors 30 and 70 from being separated downward (in the second direction) even without assembling the rear holder 80 to be described below. Therefore, it is also possible to deliver the parts except the vertical terminal 73 and the rear holder 80 in an assembled state or take them to an installation location (for example, the inside of a vehicle).

The vertical terminal 73 is accommodated in the second space 32 of the vertical housing 30. As shown in FIG. 2, the vertical terminal 73 has a substantially cylindrical shape, and in the front portion there is a connection head 74 inserted into the second context spring 55 of the horizontal terminal 50. The retainer 75 is coupled to the connection head 74, the retaining pieces 76 of the retainer 75 are caught inside the second space 32 of the vertical housing 30 so that the vertical terminal 73 is in the opposite direction. It prevents separation. Figures of the engaging pieces 76 are hung inside the second space 32 of the vertical housing 30 is shown in FIG. 3. Reference numeral 70 is an extension wire, which is connected to the vertical terminal 73 and extends downward, and is connected to other external components. The outer surface 71 of the extension wire is covered.

There is a rear holder 80 below the vertical terminal 73. The rear holder 80 is assembled to the outer case 10 with the vertical inner connectors 30 and 70 therebetween by using the fastening portion 85, so that the vertical inner connectors 30 and 70 are not separated in the second direction. Do not. And the waterproof seal 87 is compressed between the rear holder 80 and the outer case 10 to perform a waterproof function.

Next, a method of assembling a high-angle light-angle terminal according to the present invention will be described.

7 to 10, the process of assembling each component according to the assembly method of the high voltage light angle terminal according to the present invention is shown in order. Referring to this, first, as shown in FIG. 7, first, the vertical housing 30 constituting the vertical inner connectors 30 and 70 is inserted into the inner space of the outer case 10. The insertion direction is inserted from the bottom upward, that is, in the second direction, into the second insertion portion 12 of the outer case 10. The vertical terminal 73 is not yet inserted into the vertical housing 30. When the vertical housing 30 is completely inserted into the outer case 10, it touches the inner surface of the inner space and can no longer be inserted.

In this state, the horizontal inner connectors 40 and 50 are assembled. The horizontal inner connectors 40 and 50 are inserted in a first direction orthogonal to the second direction, wherein the horizontal terminal 50 is inserted into the horizontal inner connectors 40 and 50. That is, the horizontal terminal 50 is inserted into the horizontal housing 40 constituting the horizontal inner connectors 40 and 50. Referring to FIG. 8, the horizontal terminal 50 is separated from the horizontal housing 40, and after being assembled first, they are inserted into the outer case 10. In the horizontal terminal 50, the first context spring 53 and the second context spring 55 are inserted.

When the horizontal terminal 50 is inserted into the horizontal housing 40, the end portion of the horizontal terminal 50 is spaced a predetermined distance from the entrance edge of the first space 43 of the horizontal housing 40. This is because the spacer 49 protrudes in the first direction from the inlet edge of the first space 43 to space the end of the horizontal terminal 50 in a direction away from the inlet edge. Of course, the horizontal terminal 50 is in a state that can be separated in the direction opposite to the inserted direction.

After the horizontal inner connectors 40 and 50 are assembled, they are inserted into the outer case 10. The insertion direction is the first direction perpendicular to the insertion direction of the vertical housing 30, and the first insertion of the outer case 10 is performed. It is inserted through the part 13. When the horizontal inner connectors 40 and 50 are inserted, the vertical housing 30 and the horizontal housing 40 previously inserted meet each other. More precisely, the first assembly rib 35 of the vertical housing 30 is fitted in the first assembly groove 45 of the horizontal housing 40, and the second assembly rib 37 is the second of the horizontal housing 40. It is fitted into the assembling groove 47', and as a result, it can be made in detail with the assembly position of the horizontal inner connectors 40 and 50 and the vertical inner connectors 30 and 70. In addition, the vertical housing 30 is engaged with the horizontal housing 40 and may not be separated from each other.

At the same time, the support rib 36 of the horizontal housing 40 supports the end of the horizontal terminal 50 in the first direction. Therefore, the horizontal terminal 50 can be stably maintained in place without being pushed in the first direction (see FIG. 3).

Next, as shown in Figure 9, the front holder 60 is assembled to the outer case 10. The front holder 60 is assembled to the outer case 10 with the waterproof seal 69 interposed therebetween, and the fastening hook 63 of the front holder 60 is attached to the holder fastening hole 15 of the outer case 10. Is fixed. In this case, the horizontal inner connectors 40 and 50 are fixed in the inner space of the outer case 10 and cannot be separated. In addition, the vertical housing 30 engaged with the horizontal inner connectors 40 and 50 cannot be separated.

In this case, the parts except the vertical terminal 73 and the rear holder 80 are preassembled. In this state, the right angle terminal can be delivered or transferred to the assembly site. It is only necessary to assemble the vertical terminal 73 and the rear holder 80 to the provisional assembly transferred to the assembly site. As shown in FIG. 10, when the vertical terminal 73 is inserted from the bottom upward, the connection head 74 of the vertical terminal 73 is inserted into the second contact spring 55 of the horizontal terminal 50 and elastically coupled. . At the same time, the locking pieces 76 on the retainer 75 of the connection head 74 are caught inside the second space 32 of the vertical housing 30 to prevent the vertical terminal 73 from being separated in the opposite direction.

At this time, since the part of the horizontal terminal 50 of the horizontal inner connectors 40 and 50 previously assembled in the seating space 33 of the vertical housing 30 is seated to block the second space 32, The connecting head 74 of the vertical terminal 73 can be connected to the horizontal terminal 50 naturally during the ascent process. Finally, the rear holder 80 is assembled in the same direction, wherein the waterproof seal 87 is compressed in the assembly process at the front of the rear holder 80.

Looking at the assembly process of the present invention as described above, except for the vertical terminal 73 and the rear holder 80, the rest of the parts can be assembled and delivered, because the rest of the parts are engaged with each other to maintain the assembled state. Also, the assembly direction is simple, (i) after the vertical housing 30 is assembled in the second direction, and (ii) the horizontal inner connectors 40 and 50 and the front holder 60 are continuously assembled in the first direction. . Therefore, assembly can be easily performed.

Finally, when the mating connector is assembled from the front of the right angle terminal, the mating terminal is assembled to the first contact spring 53 exposed at the front of the horizontal terminal 50 and electrically connected. At this time, even if a separate safety device (finger safety) is not placed in the exposed portion assembled with the mating connector because the horizontal terminal 50 is spaced apart from the inside of the housing, a sufficient worker safety distance is secured.

In the above, even if all the components constituting the embodiment according to the present invention are described as being combined or operated as one, the present invention is not necessarily limited to these embodiments. That is, within the scope of the present invention, all of the constituent elements may be selectively combined and operated.
