Referring to the drawings, the cluster terminal connector 100 may be coupled to the butt plug 12 included in the hermetic compressor 10 .

Here, the hermetic compressor 10 may include an electrical device (not shown) and a compression device (not shown), and the butt plug 12 may penetrate into the housing 11 . The butt plug 12 may include a closed terminal 13 and a fixing portion 14 for fixing the closed terminal 13 . Hereinafter, the hermetic compressor 10 will be simply referred to as “compressor 10 ”, and the illustration and detailed description of the structure of the hermetic compressor 10 will be omitted.

Although three closed terminals 13 are provided as an example in the drawings, the arrangement and number of closed terminals 13 are not limited thereto.

The cluster terminal connector 100 may include: a cover 110 configured to cover the butt plug 12 ; a body 120 configured to accommodate the terminals 130 ; a terminal position assurance member 140 configured to seal the body 120 ; and a blocking member 150 .

In the cluster terminal connector 100, the cover 110 and the main body 120 may be integrally formed. Since the cover 110 and the main body 120 are integrally formed in the cluster terminal connector 100, it is possible to prevent external water or dust from flowing into the butt plug 12 and the closed terminal 13 through a part of the coupling cluster terminal connector 100 and the butt plug 12, thereby enhancing the sealing and waterproofing properties.

The cover 110 may be formed to cover the closed terminal 13 in the butt plug 12 and the fixing portion 14 surrounding the closed terminal 13 . The cover 110 may include a side wall 111 having a predetermined height to cover the butt plug 12 , and may have a cylindrical shape, a portion of which is recessed toward the butt plug 12 . Also, the cover 110 may have a bottom surface 112, and a portion of the cover 110 facing the main body 120 is closed, and a portion of the cover 110 facing the closed terminal 13 is open, that is, may have a cylindrical shape with a bottom. However, the shape of the cover 110 is not limited to the cylindrical shape, and the cover 110 may have various shapes that are coupled to and cover the butt plug 12 and the fixing part 14 . Also, a plurality of through holes 113 may be formed on the bottom surface 112 of the cover 110 to allow the closed terminals 13 to penetrate into the cover 110 and contact the terminals 130 in the body 120 .

The main body 120 may include a slot 121a into which the plurality of terminals 130 are inserted. Hereinafter, a portion of the main body 120 in which the terminal 130 is accommodated is referred to as a first end portion 121, a portion of the main body 120 on the opposite side of the first end portion 121 is referred to as a second end portion 122, and the main body 120 The two outer sides will be referred to as sides 123 .

In the butt plug 12, three closed terminals] 3 may be arranged approximately in a triangular shape. The three terminals 130 are arranged parallel to each other to respectively contact the closed terminals 13 arranged in a triangular form, and thus, the main body 120 may have an approximately "V" shape.

Although three closed terminals 13 and three terminals 130 are provided in this embodiment, various changes may be made to the number of closed terminals 13 . In addition, the shape of the main body 120 may be appropriately changed based on the arrangement and number of the closed terminals 13 .

The terminal position securing member 140 may be included in the first end portion 121 of the main body 120 .

The terminal position assurance member 140 may include a main frame 141 , a plurality of guides 142 inserted into the slots 121 a of the main body 120 , and a first locking portion 143 coupled to the side surface of the main body 120 .

The guide 142 may extend a predetermined length from the main frame 141 to be inserted into the slot 121 a, and may include a groove 142 a formed on a surface of the guide 142 to accommodate the electric wire 131 . For example, three guides 142 may be formed to be installed in the three terminals 130 and the slot 121a, respectively.

The first locking part 143 may be formed to be coupled to the outer side 123 of the main body 120 . For example, a pair of first locking parts 143 may be coupled to both side surfaces 123 of the main body 120 . And the locking part 143 may be formed to extend parallel to the outermost guide 142 toward the direction in which the first locking part 143 is coupled to the main body 120 . Also, the first locking part 143 may have a ring shape to be locked. Since the pair of first locking parts 143 have their own elasticity and correspond to both sides of the main body 120 , the first locking parts 143 can be coupled to the main body 120 and the A locking portion 143 is maintained in a state of being elastically coupled to the main body 120 .

The first protrusion 124 may be formed to protrude from the side surface 123 of the main body 120 by a predetermined height at a position coupled with the first locking portion 143 such that the first locking portion 143 is locked with the first protrusion 124 .

By pushing the terminal 130 into the first end portion 121 of the main body 120 in a state where the terminal 130 is inserted into the main body 120 , the terminal position assurance member 140 may be coupled to the main body 120 . 6 , when the terminal position assurance member 140 is inserted into the main body 120 , the guide 142 may press-contact with the bent portion 130 a of the terminal 130 in the slot 121 a of the main body 120 to push the terminal 130 into the main body 120 .

According to an exemplary embodiment, the terminal position assurance member 140 may be used to determine whether the terminal 130 is inserted into the main body 120 at an appropriate position. For example, when the terminal 130 is not coupled in place, the terminal position assurance member 140 may not be fully coupled to the main body 120 . Therefore, in the process of inserting the terminal position securing member 140 into the main body 120, it can be determined whether the terminal 130 is inserted into the proper position, and the space between the terminal 130 and the closed terminal 13 can be stably maintained by pushing the terminal 130 into the proper position. connection. Also, since the terminal position assurance member 140 is disposed in the direction in which the terminal 130 is inserted (eg, the direction in which the terminal 130 is pulled out from the main body 120 ), the terminal position assurance member 140 can prevent the terminal 130 from being pulled out of the housing 130 . The terminal position assurance member 140 can also prevent foreign matter from flowing into the main body 120 .

The blocking member 150 may be included in the second end 122 of the body 120 . For example, a predetermined opening or slot (not shown) may be formed in the second end 122 of the main body 120, and the blocking member 150 may be provided to block the opening or slot.

The blocking member 150 may include a main frame 151 , an extension part 152 formed to protrude from the main frame 151 , and a second locking part 153 coupled to the main body 120 .

The main frame 151 may be coupled to the second end 122 of the main body 120 and may have a substantially plate-like shape.

The extension part 152 may be formed to protrude from the main frame 151 by a predetermined length. For example, relatively long extensions 152 may be formed in a central portion of the blocking member 150 , and relatively short extensions 152 may be formed on both sides of the blocking member 150 based on the shape of the main body 120 . However, the shape of the extension part 152 is not limited to the drawings, and may be substantially variously changed based on the shape of the main body 120 .

A pair of second locking parts 153 may be formed in both end parts of the main frame 151 to extend toward a direction in which the second locking parts 153 are coupled to the body 120 and to both side surfaces 123 of the body. And, the second locking part 153 may have a ring shape to be locked.

Since the pair of second locking parts 153 are formed in parallel with each other, the second locking parts 153 may be coupled to the body 120 only by inserting the blocking member 150 into the body 120 and may remain in a state of being elastically coupled to the body 120 .

In addition, the second protrusion 125 may be formed to protrude from the side surface 123 of the main body 120 by a predetermined height at a position where the second locking portion 153 is coupled so that the second locking portion 153 is locked with the second protrusion 125 .

According to an exemplary embodiment, the cover 110 and the main body 120 may be integrally formed in the cluster terminal connector 100 , so that the portion of the cluster terminal connector 100 coupled to the butt plug 12 may be more effectively hermetically sealed. Therefore, the structure of the cluster terminal connector 100 and the process of assembling the cluster terminal connector 100 with the butt plug 12 can be simplified, and workability can be improved. In other words, the assembling process can be completed by inserting the butt plug 12 into the cluster terminal connector 100 without using any other components, so the process can be simplified and the workability can be improved.

As described above, according to the exemplary embodiment, the cover and the main body may be integrally formed in the cluster terminal connector, and thus the cluster terminal connector may effectively prevent water or dust from flowing into the closed terminal.

Also, the structure of the cluster terminal connector and the process of assembling the cluster terminal connector and the hermetic compressor can be simplified, and workability can be enhanced.

The effects of the cluster terminal connector and the hermetic compressor including the cluster terminal connector are not limited to the above-mentioned effects. And, other unmentioned effects can be clearly understood from the above description by those having ordinary skill in the technical field to which the present disclosure pertains.
