Description

CONNECTING PACKAGE FOR REFRIGERATOR

COMPRESSOR

Technical Field

[1] The present invention relates generally to a connecting package for a refrigerator compressor, and more particularly to a connecting package for a refrigerator compressor, which can be directly mounted on a body of a refrigerator compressor with a motor starter relay element mounted therein, and which is capable of directly mounting thereto a motor protector and a running capacitor at the same time.

Background Art

[2] Generally, a connecting package for a refrigerator compressor is equipped with a

PTC (positive temperature coefficient) starter relay element for starting an AC motor used with the refrigerator compressor. Besides the PTC starter relay element, an overload protector for protecting a motor from overload or a running capacitor (RC) for improving an efficiency of the motor can be provided in the connecting package. Disclosure of Invention Technical Problem

[3] However, when installing the connecting package in the refrigerator compressor, the overload protector or the running capacitor must be individually wired through separate connecting structures. For this reason, connecting wires and mounting brackets must be provided at an outer portion of the refrigerator compressor. Therefore, not only is a structure of a product complicated, but also maintenance and repair works are difficult while causing an assembling error, thereby degrading quality and productivity of products.

[4] In addition, such connecting package connected to the compressor body may be disconnected therefrom due to an accidental external force, so that the compressor may be damaged by overload. It would therefore be of benefit to provide a structure for stably fixing the connecting package to the compressor body.

[5] Accordingly, it is necessary to develop a connecting package for a refrigerator compressor capable of easily performing with a single package unit a connecting operation such as start of a refrigerator compressor, protection of a motor from overload, or improvement of motor efficiency, as well as in which a fixing structure to the compressor body is provided to thus secure the maintenance of stable connecting state. Technical Solution

[6] The present invention is directed to a connecting package for a refrigerator compressor that substantially obviates one or more problems due to limitations and disadvantages of the related art.

[7] It is an object of the present invention to provide a connecting package for a refrigerator compressor capable of easily performing with a single package unit a connecting operation such as start of a refrigerator compressor, protection of a motor from overload, or improvement of motor efficiency, as well as in which a fixing structure to the compressor body is provided to thus secure the maintenance of stable connecting state.

[35] Preferred embodiments of the invention will now be described in detail with reference to the accompanying drawings.

[36] FlG. 1 is a perspective view of a connecting package 100 for a refrigerator compressor according to one embodiment of the present invention. The connecting package includes a base 10, a cover 30 having a running capacitor mounting pole 3. An overload protector 50 for a motor is mounted to the connecting package.

[37] FlG. 2 is an exploded perspective view of the connecting package of FlG. 1. The connecting package includes a base 10, a cover 30 coupled to the upper portion of the base, and a motor starter relay element 20 mounted between the base and the cover. The overload protector 50 is mounted inside of the cover from the bottom portion of the base.

[38] The base 10 is formed in substantially rectangular shape, and includes at one end side an opening mounting section 15 as a space for mounting the overload protector 50 for motor, and at center portion thereof a mounting section 12 as a space for mounting the starter relay element 20.

[39] Coupling holes 19 are formed at both sides of the mounting section 12 for the starter relay element such that downwardly protruding portions 39 of the cover 30 are to be inserted and coupled thereinto. As is not shown in the drawing, engagement steps are formed inside the coupling holes such that hook ends 39' of the downwardly protruding portions 39 are hook-engaged with the engagement steps.

[40] The mounting section 12 for starter relay element has at its center bottom surface supporting protrusions 17 for supporting a disc type positive temperature coefficient (PTC) element 25 in an upstanding state.

[41] The upper edge portion of the base is formed with a stepped portion 13 so as to maintain the same leveled surface as the lower edge portion of the cover when the cover is to be coupled to the upper portion of the base.

[42] When the cover is coupled to the base, the stepped portion 13 is covered with the edge portion of the cover so that it is expected that moistures such as by rainwater cannot be penetrated into a space between the base and the cover.

[43] A pair of ear portions 18 is formed on the both sidewalls of the base below the stepped portion 13, serving as a grip for holding by hands when decoupling the cover from the base.

[44] A rod-type running capacitor mounting pole 37 is formed on the cover 30 to mount the running capacitor while to support the same. The cover is coupled to the upper portion of the base. To this end, two coupling portions 39 downwardly protruded from the cover and having the hook ends are inserted into the coupling holes 19 of the base 10 so that the hook ends are engaged with the engagement steps 36'(see FlG. 6) in the coupling holes.

[45] The cover includes thereon a first connecting slot 35 at one end side thereof for connection with a connecting terminal 55 of the overload protector 50 connected to an external power source, a second connecting slot 33 at the center side thereof for connection with a connecting terminal 21b of the relay element 20 connected to the external power source, and third two connecting slots 31 at the other end side thereof for connection with receptacles 27 of a jumper 27'of the relay element 20 connected to a quick connector of the running capacitor.

[46] Herein, the first and third connecting slots 35 and 31 have upwardly protruded edges 35a and 31a so that they form a structure that foreign substance or rainwater cannot be easily penetrated thereinto when connected with the external power source and the running capacitor.

[47] In addition, as is not shown in FlG. 2, the cover includes thereon releasing slots 39a and 35a adjacent to portions from which two downwardly protruded coupling portions 39 for coupling with the base and the downwardly protruded portion 36 (see FlG. 6) for fixing the overload protector 50 extend. The releasing slots are provided to facilitate insertion of an elongate releasing means such as a ruler in shape corre sponding to the releasing slots, into the releasing slots when decoupling the cover and the overload protector coupled to the base by the coupling portions from the base.

[48] Further, the cover includes at both outer ends thereof clamp protrusions 38a and

38b for stably fixing the connecting package of the invention to a compressor body for refrigerator, i.e., a compressor fence 90 (see FIGS. 11 to 13). The clamp protrusions are integrally formed to the cover.

[49] A mounting structure of the compressor fence with the clamp protrusions of the cover will be described later with reference to FIGS. 10 to 13.

[50] The motor starter relay element 20 is mounted between the base and the cover.

[51] The relay element 20 includes a disc-type positive temperature coefficient (PTC) element 25 disposed in a recess at the center of the base, rectangular conductive plates 21 and 23 disposed opposite to the PTC element, and U-shaped resilient connecting members 29 electrically connecting between the respective conductive plates and the PTC element with its open ends resiliently contacting the PTC element and its closed ends disposed fixedly to the respective conductive plates 21 and 23 by means of such as a welding.

[52] The conductive plates 21 and 23 are respectively connected in parallel with a pin connector 21c connected to a primary winding side of the motor and a pin connector 23c connected to a secondary winding side of the motor, and are provided with connecting terminals 21a and 23a connected to the running capacitor through the jumper 27.

[53] In addition, the conductive plate 21 to which the pin connector 21c connected to the primary winding side of the motor is attached is provided with the connecting terminal 21b for electrical connection with the external power source.

[54] A protrusion 23b of the other conductive plate 23 positioned corresponding to the connecting terminal 21b is one for positioning the conductive plate 23 at the same height as the conductive plate 21, which protrusion is inserted into a protruded recess (not shown) of the cover to support the conductive plate 23 at the same height of the conductive plate 21.

[55] FlG. 3 is a bottom view of a back surface of the base. The base includes an overload protector mounting section 15 at its one end side and two pin connecting holes 11 at its center portion for connection to the primary or secondary winding of the motor.

[56] To the back surface of the pin connecting holes, the pin connectors of the relay element are correspondingly disposed. At both sides of the pin connecting holes 11, the coupling holes 19 having the engagement steps 19a engaged with the hook ends of the downwardly protruded portions of the cover are provided.

[57] FlG. 4 is a front view of the base. The base includes the overload protector mounting section 15 at its one end side, and a center internal space for mounting the relay element. The bottom of the internal space includes two pin connecting holes 11 connected to the primary or secondary winding of the motor at its one end side, and two supporting portions 17 at its center portion for supporting the disc-type PTC element of the relay element in an upstanding state.

[58] At both sides of the internal space in which the relay element is mounted, the coupling holes 19 for coupling with the cover are provided, and the engagement steps 19a are formed inside the coupling hole to engage with the hook ends of the downwardly protruded portions of the cover.

[59] Engagement steps 15a are provided at the both sidewalls of the overload protector mounting section 15 of the base for supporting both sidewalls 53 (see FIG. 8) of the overload protector when mounting thereinto the overload protector.

[60] FIGS. 5 to 7 are a front view, a bottom view of the cover and a bottom view of the cover in which the relay element is mounted, respectively.

[61] As described with reference to FlG. 2, the cover includes thereon a first connecting slot 35 at one end side thereof for connection with a connecting terminal 55 of the overload protector 50 connected to an external power source, a second connecting slot 33 at the center side thereof for connection with a connecting terminal 21b of the relay element 20 connected to the external power source, and third two connecting slots 31 at the other end side thereof for connection with receptacles 27'of a jumper 27 of the relay element 20 connected to a quick connector of the running capacitor.

[62] Herein, the first and third connecting slots 35 and 31 have upwardly protruded edges 35a and 31a so that they form a structure that foreign substance or rainwater cannot be easily penetrated thereinto when connected with the external power source and the running capacitor.

[63] In addition, the cover includes thereon releasing slots 39a and 35a adjacent to portions from which two downwardly protruded coupling portions 39 for coupling with the base and the downwardly protruded portion 36 for fixing the overload protector 50 extend. The releasing slots are provided to facilitate insertion of an elongate releasing means such as a ruler in shape corresponding to the releasing slots, into the releasing slots when decoupling the cover and the overload protector coupled to the base by the coupling portions from the base.

[64] The two downwardly protruded coupling portions 39 of the cover for coupling to the base are coupled to the base such that the hook ends 39'thereof are engaged with the engagement steps of the coupling holes of the base, and the downwardly protruded coupling portion 36 for coupling to the overload protector supports the overload protector such that the hook end 36 'thereof is engaged with the engagement step 57'(see FlG. 8) of the body of the overload protector.

[65] At the back surface of the cover, a recess 32 is disposed in which the disc type PTC element 25 of the relay element is positioned in an upstanding state, and whose both sides have engagement steps 32a for supporting both surfaces of the PTC element disposed in the recess.

[66] In addition, two semi-cylindrical protrusions 34 downwardly protruded from the upper surface of the cover are provided to support the pin connectors 21c and 23c when the relay element is mounted to the back surface side of the cover.

[67] The construction of the relay element mounted to the back surface side of the cover is the same as that described in FlG. 2.

[68] FlG. 8 is a perspective view of the overload protector. Such overload protector 50 is a device for protecting the motor from overload, and includes two parallel triangular planar stoppers 59 serving as a stopper and supporter when mounted to the connecting package of the invention, the pin connector 51 connected to the primary winding side of the motor, and the terminal 55 for electrical connection to an external. The two planar stoppers 59 each have a semi-circular cut-out for preventing blocking of the pin connecting holes 11 of the base when the overload protector is mounted to the connecting package of the invention.

[69] When mounting the overload protector to the connecting package of the invention, the both sidewalls 53 of the overload protector are supported by both engagement steps 15a of the overload protector mounting section of the base, and the hook end 36'of the downwardly protruded coupling portion 36 of the cover is engaged with the engagement step 57'formed by the bent protrusion 57 of the overload protector, so that the overload protector can be detachably mounted to the connecting package of the invention.

[70] As described before, the coupled overload protector 50 can be easily released by inserting elongate and planar releasing means such as a ruler into releasing slot 39b and applying a force using a lever rule.

[71] Such overload protector is the same one as that disclosed in USP No. 4,241,370, the disclosure of which is incorporated herein by reference in its entirety.

[72] FlG. 9 is a perspective view of the running capacitor 70 mounted to the mounting pole 37 of the cover. The running capacitor includes two quick connectors 71 at its lower portion and the fastening tab at one side of the upper portion thereof, which is inserted into the mounting pole. The fastening tab is formed with a protruded planar portion which has a hole 71 and a slot 73a extending from the hole up to the end of the planar portion, so that when the running capacitor is inserted into the mounting pole through the hole of the fastening tab, the hole has room for enlargement due to the slot 73a, which facilitates mounting or releasing of the running capacitor to or from the mounting pole.

[73] Similarly, the mounting pole 37 also has a construction for facilitating mounting or releasing when the running capacitor 70 is mounted or released to or from the mounting pole 37.

[74] As illustrated in FIGS. 1, 2 and 11, the running capacitor mounting pole 37 has a longitudinal slot 37a at its end portion and engagement projections 37b each having an inclined surface at the outer surfaces of opposite sides to the slot.

[75] In addition, the running capacitor mounting pole 37 also includes a triangular vertical positioning plate 37c extending between the pole and the upper cover portion. The vertical plate is a positioning element for positioning a location to which two quick connectors 71 of the running capacitor are to be inserted, i.e., two connecting slots 31 of the cover 30, when mounting the running capacitor. As illustrated in FlG. 2, two vertical plates 37c extending toward the releasing slot 39a and the connecting slot 35 of the cover are provided so that the running capacitor can therefore be automatically mounted only toward the connecting slot 31 when mounted to the cover.

[76] The slot 37a of the mounting pole facilitates mounting or releasing of the running capacitor such that opposite end portions to the slot resiliently contact around the hole 73 of the fastening tab when the running capacitor is mounted or released to or from the mounting pole. The engagement projections 37b formed on the outer surfaces of the opposite end surfaces to the slot of the pole are formed with inclined surfaces, so that upon mounting, the fastening tab of the running capacitor smoothly passes the engagement projections, and after mounting of the running capacitor to the mounting pole, the running capacitor is hardly released from the mounting pole.

[77] Meanwhile, in order to prevent the connecting package of the invention connected to the compressor, i.e., the compressor fence 90 from being easily disconnected therefrom to thus secure an operation of the connecting package, the connecting package includes clamp means integrally formed to the cover.

[78] Constructions of such clamp means and a clamped state thereby are illustrated well in FIGS. 10 to 13.

[79] FIG. 10 is a perspective view of the compressor fence to which the connecting package of the invention is attached, FIG. 11 is a perspective view illustrating the connecting package, in which the running capacitor of FIG. 9 is mounted, and which is attached to the compressor fence of FIG. 10, and FIGS 12 and 13 is a perspective view illustrating a state where the clamp protrusion of the connecting package of the invention is coupled to the compressor fence.

[80] The compressor fence 90 attached to the compressor body by welding, etc. includes a center circular compressor terminal 95 with three pins protruded from the compressor body, and opposite vertical ends 91a and 91b to the center compressor terminal. The vertical ends have fixing holes 91a'and 91b'so that when the connecting package of the invention is connected to the compressor, as shown in FIG. 1, the pin connector of the overload protector and the first and second pin connecting holes of the base, i.e., three pin connecting holes are inserted into the three pins of the circular compressor connecting terminal 95 as well as the clamp protrusions of the connecting package are coupled into the fixing holes of the compressor fence.

[81] The fixing holes of the opposite vertical ends are formed such that only at least one hole is formed to the respective vertical ends. The number and shape of the fixing hole however is not limited as illustrated, but can be changed.

[82] The clamp protrusions 38a and 38b formed to opposite outer ends of the cover have the downward extension portions and the engagement projections 38a 'and 38b'formed to the ends of the extension portions. The downward extension portions may be preferably formed from a resilient material such that when coupled to the compressor fence, the extension portions resilien y contact the opposite vertical ends of the compressor fence by the press-contact therewith.

[83] At least one engagement projection of the clamp protrusions is formed with a guide inclined surface for easy coupling (in the drawing, the engagement projection 38a'is illustrated as the guide inclined surface).

[84] Since the number of the clamp protrusions 38a and 38b formed on the outer surfaces, respectively, of the opposite ends of the cover corresponds to the number of the fixing holes 91a'and 91b' formed to the opposite vertical ends of the compressor fence 90 into which the clamp protrusions are coupled, the number thereof can be changed according to change of the compressor fence. Industrial Applicability

[85] As described before, the connecting package for a refrigerator compressor is provided which is capable of easily performing with a single package unit a connecting operation such as start of a refrigerator compressor, protection of a motor from overload, or improvement of motor efficiency, as well as in which a fixing structure to the compressor body is provided to thus secure the maintenance of stable connecting state, thereby providing easy assembly, high quality and excellent productivity.

[86] The forgoing embodiments are merely exemplary and are not to be construed as limiting the present invention. The present teachings can be readily applied to other types of apparatuses. The description of the present invention is intended to be illustrative, and not to limit the scope of the claims. Many alternatives, modifications, and variations will be apparent to those skilled in the art.
