DOVETAIL STRUCTURE OF CONNECTOR

Abstract

The present invention provides a dovetail structure of a connector that can be disposed on a first joint surface and a second joint surface of a casing. The dovetail structure includes a pin module and a slot module. An interference structure formed by the pin module and the slot module enables the two connectors with a dovetail structure to be assembled easily to achieve a stable combination.

[0027] With reference to FIG. 1 for a schematic view of a dovetail structure applied to a connector in accordance with an embodiment of the present invention, the connector having a dovetail structure 10 comprises a casing 12, a pin module 14 and a slot module 16.

[0028] The casing 12 provides a first joint surface 122 and a second joint surface 124.

[0029] The pin module 14 is disposed on the first joint surface 122 and has a first guide block 142 and a second guide block 144. The first guide block 142 and the second guide block 144 are parallel to each other and provided to form a first dovetail tenon 146 and a second dovetail tenon 148 respectively.

[0030] With reference to FIG. 2 for a schematic view of installing a pin module to a casing in accordance with the present invention, an outer edge distance dl between the first guide block 142 and the second guide block 144 of the first dovetail tenon 146 is smaller than the outer edge distance d2 between the second guide block 144 and the first guide block 142 of the second dovetail tenon 148. In this embodiment, the outer edge distance refers to the distance between the outer edge of the first guide block 142 and the outer edge of the second guide block 144 as shown in the figure.

[0031] In this embodiment, the pin module 14 further comprises a first stopper 1410 having a first bevel 1412. The first stopper 1410 is installed at the second dovetail tenon 148, and the first stopper 1410 can also be installed at any position of the pin module 14 in another embodiment. The first guide block 142 and the second guide block 144 of the second dovetail tenon 148 are coupled to each other by a connecting member 1414 to form a first stopper 1410, and the structure of the connecting member 1414 can enhance the connection strength. In another embodiment, the structure of the connecting member 1414 is not limited to the aforementioned arrangement of connecting to the first guide block 142 and the second guide block 144 only.

[0032] In another embodiment, the two outer edges of the dovetail tenon can be formed into ribs 1416 respectively.

[0033] With reference to FIG. 3 for a schematic view of installing a slot module to a casing in accordance with the present invention, the slot module 16 is disposed on the second joint surface 124 and has a first guide slot 162 and a second guide slot 164. The first guide slot 162 and the second guide slot 164 are parallel to each other and provided for forming a first dovetail tenon hole 166 and a second dovetail tenon hole 168 respectively. An inner edge distance d3 between the first guide slot 162 and the second guide slot 164 of the first dovetail tenon hole 166 is greater than the inner edge distance d4 between the first guide slot 162 and the second guide slot 164 of the second dovetail tenon hole 168. In this embodiment, the inner edge distance d3, d4 refer to the distance between the inner edge of the first guide slot 162 and the inner edge of the second guide slot 164 as shown in the figure. In this embodiment, the inner edge distance d3, d4 of the dovetail tenon hole 166, 168 is greater than or equal to the outer edge distance dl, d2 of the dovetail tenon 146, 148.

[0034] In another embodiment, two inner edges of the dovetail tenon hole are formed into ribs respectively (not shown in the figure).

[0035] In this embodiment, the slot module 16 further comprises a second stopper 1610, and the second stopper 1610 has a second bevel 1612. The second stopper 1610 is disposed at the first dovetail tenon hole 166. In another embodiment, the slot module 16 can be disposed at any position of the slot module 16. Wherein, the second stopper 1610 is configured to be corresponsive to the first stopper 1410. When the first bevel 1412 of the first stopper 1410 of any connector touches the second bevel 1612 of the second stopper 1610 of another connector, the first bevel 1412 is acted on the second bevel 1612, and after the first stopper 1410 and the second stopper 1610 are staggered with each other, the first stopper 1410 and the second stopper 1610 are limited and latched with each other.

[0036] With reference to FIGS. 4 to 7 for the schematic views of assembling a first connector with a dovetail structure and a second connector with a dovetail structure in accordance with an embodiment of the present invention, FIG. 5 is a front view showing the assembly of the first connector with the dovetail structure and the second connector with the dovetail structure, FIG. 6 is a rear view showing the assembly of the first connector with the dovetail structure and the second connector with the dovetail structure, and FIG. 7 is a cross-sectional view of a dovetail structure of an embodiment of the present invention.

[0037] In FIG. 4, a first connector 20 and a second connector 30 are provided.

[0038] The first connector 20 comprises a first casing 202, a first pin module 204 and a first slot module 206 which are substantially the same as those described above, and thus will not be repeated.

[0039] In FIGS. 5 to 7, the first pin module 204 and the first slot module 206 are disposed on the first casing 202. The first pin module 204 is provided for forming a first dovetail tenon 2042 and a second dovetail tenon 2044. Wherein, an outer edge distance of the first dovetail tenon 2042 is smaller than the outer edge distance of the second dovetail tenon 2044.

[0040] The first slot module 206 is provided for forming a first dovetail tenon hole 2062 and a second dovetail tenon hole 2064. Wherein, an inner edge distance of the first dovetail tenon hole 2062 is greater than the inner edge distance of the second dovetail tenon hole 2064, and the inner edge distance is greater than or equal to the outer edge distance of the first dovetail tenon 2042 (or the second dovetail tenon 2044).

[0041] The second connector 30 comprises a second casing 302, a second pin module 304 and a second slot module 306, which are substantially the same as those described above, and thus will not be repeated.

[0042] The second pin module 304 and the second slot module 306 are disposed at the second casing 302.

[0043] The second pin module 304 is provided for forming a third dovetail tenon 3042 and a fourth dovetail tenon 3044. Wherein, the outer edge distance of the third dovetail tenon 3042 is smaller than the outer edge distance of the fourth dovetail tenon 3044.

[0044] The second slot module 306 is provided for forming a third dovetail tenon hole 3062 and a fourth dovetail tenon hole 3064. Wherein, the inner edge distance of the third dovetail tenon hole 3062 is greater than the inner edge distance of the fourth dovetail tenon hole 3064, and the inner edge distance is greater than or equal to the outer edge distance of the third dovetail tenon 3042 (or the fourth dovetail tenon 3044).

[0045] In FIG. 7, when the third dovetail tenon 3042 and the fourth dovetail tenon 3044 move along the first dovetail tenon hole 2062 and the second dovetail tenon hole 2064 respectively, the first slot module 206 combines with the second pin module 304. Until the third dovetail tenon 3042 touches the second dovetail tenon hole 2064 and the fourth dovetail tenon 3044 touches the first dovetail tenon hole 2062, the third dovetail tenon 3042 and the second dovetail tenon hole 2064 have interference with each other, and the first dovetail tenon 3044 and the first dovetail tenon hole 2062 have interference with each other to produce deformations, so that the first slot module 206 has a tight fit with the second pin module 304. The combined state is shown in FIGS. 5 and 6.

[0046] It is noteworthy that the first dovetail tenon hole 2062 adjacent to the casing 20 can be formed into a first deformation slot 2066; and the fourth dovetail tenon 3044 adjacent to the casing 30 can be formed into a second deformation slot 3046. The first deformation slot 2066 and the second deformation slot 3046 are provided for accommodating the pressing and squeezing forces caused by the tight fit.

[0047] While the invention has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of the invention as set forth in the claims.
