FIELD OF THE INVENTION

The present invention is related to a connector assembly structure of a terminal used for converting connecting wires, which is applied to the converting terminals of various cooling system, and can achieve the requirement of converting various connecting wires by the design of the terminal structure of the standard connectors.

DESCRIPTION OF THE RELATED ART

The diameters of the connecting wires of the cooling systems vary with the electrical resistance of the connecting wires. For example, a connecting wire with a specification of UL 1015 18 AWG corresponds to a diameter of 2.80 mm, and a connecting wire with a specification of UL 1015 22 AWG corresponds to a diameter of 2.40 mm. However, it is consuming that the frames of the cooling systems are produced by different specifications in order to fit different diameters of the connecting wires. Therefore, in order to satisfy the market demand of the connecting wires with different diameters, a terminal structure for standard connectors is designed to achieve the requirement of converting various connecting wires.

FIG. 1shows a schematic diagram of a conventional terminal structure of connecting wires. The conventional terminal structure of connecting wires is disposed on the frame10of a cooling system. The frame10is hollow and has a motor base11on the central portion thereof. A motor stator and a motor rotor are mounted on the motor base11. Further, the motor base11is connected to the frame10through a plurality of ribs12, wherein at least one rib12has a wire groove13through which the connecting wires of the motor stator extend out to connect to a first connector21of the frame10. The first connector21has two connecting pins211disposed thereon.

Additionally, the conventional terminal structure further has a second connector22that is connected to the connecting wires to be converted. The second connector22has two receiving holes221in which the connecting pins211of the first connector21insert and affix. The interconnection and coupling of the connecting pins211and the receiving holes221between the first connector21and the second connector22can achieve the objective of electrically connecting and converting various connecting wires.

However, the conventional terminal structure has the following disadvantages:

1. The second connector22will unfasten from the first connector21easily. The first connector21and the second connector22interconnect by the coupling of the connecting pins211and the receiving holes221, and are affixed by the friction therebetween. Moreover, the cooling system generates high frequency vibration during operation. Therefore, the second connector22will unfasten from the first connector21easily.

2. It is difficult to detach the second connector22. In order to improve the above-mentioned problem, another conventional terminal structure is provided with increasing the friction between the connecting pins211and the receiving holes221, or with other embedded structure (for example, protrusions and grooves). However, in such conventional terminal structure, it is difficult to attach the second connector22to the first connector21, and it is also difficult to detach the second connector22from the first connector21.

Consequently, there is a need for improved connector assembly structure of a terminal to solve the above-mentioned problems that the second connector22will unfasten from the first connector21easily and it is difficult to detach the second connector22.

SUMMARY OF THE INVENTION

The main object of the present invention is to provide a connector assembly structure of a terminal used for converting connecting wires, comprising a first connector and a second connector disposed on a frame of a cooling system. The first connector is connected to the connecting wires that are connected to a stator of a motor of the cooling system, and is affixed on the frame. The second connector is connected to the connecting wires to be converted. The electrically interconnection between the first connector and the second connector can satisfy the requirement of converting various connecting wires.

The second connector has at least one hook on the periphery thereof. The cooling system has a releasing hole that corresponds to the hook and can be engaged with the hook. The releasing hole is disposed on the frame and extends through the frame.

As a result, the second connector is secured at a fix position and will not unfasten from the first connector even under high frequency vibration for a long time. On the other hand, the second connector also has an advantage of being detached fast by utilizing the releasing hole. Thus, this invention can satisfy the requirement of converting various connecting wires fast and easily.

DETAILED DESCRIPTION OF THE INVENTION

The present invention is related to a connector assembly structure of a terminal used for converting connecting wires, which is applied on the frames of various cooling systems. Several embodiments for illustrating the relative positions of all elements of the present invention are described as follows.

Referring toFIG. 2, the frame10is hollow and has a motor base11on the central portion thereof. A motor stator and a motor rotor are mounted on the motor base11. Further, the motor base11is connected to the frame10through a plurality of ribs12, wherein at least one rib12has a wire groove13through which the connecting wires of the motor stator extend out. A terminal is disposed on the position where the wire groove13connects to the frame10.

Referring toFIGS. 2 and 3, the terminal comprises a first connector21and a second connector22. The first connector21is connected to the connecting wires that are connected to a stator of a motor, and has two connecting pins211on one end thereof. The second connector22is connected to the connecting wires to be converted, and has two receiving holes221corresponding to the connecting pins211of the first connector21. The interconnection and coupling of the connecting pins211and the receiving holes221can achieve the objective of electrically connecting and converting various connecting wires.

The first connector21is affixed on the frame10. The second connector22has two hooks222disposed on the two sides thereof. The frame10has two releasing holes14that corresponds to the hooks222of the second connector22and are engaged with the hooks222. Preferably, the releasing holes14extend through the frame10.

Referring toFIGS. 3 and 4, to detach the second connector22, a strip is utilized to urge against the hooks222through the releasing holes14so that the hooks222can unfasten from the releasing holes14. Thus, the second connector22can be removed from the first connector21.

FIG. 5shows another embodiment of the releasing holes214. The releasing holes14ofFIG. 4are disposed on the frame10. Alternatively, the releasing holes214ofFIG. 5are disposed on the plates212that protrudes from the two sides of first connector21. In the same way, the releasing holes214must correspond to the hooks222of the second connector22so that it has the functions of being engaged with the hooks222and affixing the second connector22. The plate212has a pinhole213through which the strip urges against the hook222so that the hook222can unfasten from the releasing hole214.

In conclusion, the second connector is secured at a fix position and will not unfasten from the first connector even under high frequency vibration for a long time due to the cooperation of the hooks and the releasing holes according to the present invention. On the other hand, the second connector also has an advantage of being detached fast by utilizing the releasing hole. Accordingly, the disadvantages of the conventional terminal structure are solved thoroughly.

Additionally, a terminal structure according to a third embodiment of the present invention is shown inFIG. 6. The terminal structure comprises a first connector21and a second connector22. The first connector21is affixed on the frame10. The hook223is disposed on the top side with relative large area of the second connector22. The first connector21has a releasing hole215that corresponds to the hook223. In the same way, the embodiment also can achieve the objective of being secured tightly and being detached fast.

From the invention thus described, it will be obvious that this invention as described above is provided for explanation and that the invention may be varied in many ways, where such variations are not to be regarded as departing from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended for inclusion within the scope of the following claims.
