This is done for convenience of illustration only and to provide a general sense of the scope of the invention. Thus, unless clearly indicated to the contrary, such description should be read to include one, at least one and the singular also includes the plural.

In the present disclosure, the terms "comprise," "include," "have," "contain," or any other similar terms are intended to cover non-exclusive inclusions. For example, an element, structure, article, or apparatus that comprises a plurality of elements is not limited to only those elements but may include other elements not expressly listed or inherent to such element, structure, article, or apparatus. In addition, unless expressly stated to the contrary, the term "or" is intended to mean an inclusive "or" rather than an exclusive "or".

Fig. 1 is a schematic structural diagram of a floating connector according to a first embodiment of the present invention. In fig. 1, a floating connector 10 is capable of connecting a first circuit board 2 and a second circuit board 4 as in fig. 2, and fig. 2 is a schematic view illustrating the use of the floating connector of fig. 1 in combination with circuit boards according to the present invention.

In fig. 1 and 2, the floating connector 10 includes a female end 12 and a male end 14. In fig. 2, male end 14 is shown inserted into female end 12 in a straight down manner (e.g., Y-direction in the drawing of fig. 2).

Referring to fig. 3 to 4 together, fig. 3 is a schematic structural view illustrating the female terminal of fig. 1 according to the present invention; and, FIG. 4 includes FIGS. 4a through 4d, which are detailed block diagrams illustrating the components of the female terminal of FIG. 1 according to the present invention. In fig. 3, the female terminal 12 includes a contact 122, a first fixing member 124, a housing 126 and a first terminal 128.

The contact member 122 can be engaged with the first fixing member 124 to be retained on the first fixing member 124. Here, the contact 122 is an O-shaped body to form an annular space SP. In fig. 4a, the contact 122 further includes a second body 1222, an extension 1224, a reinforcement rib 1226, and a first opening 1228. The second body 1222 forms an annular space SP and one side of the annular space SP is a leading edge surface of the contact 122. The extension blocks 1224 are connected to the second body 1222 and disposed at both sides of the second body 1222, respectively. The reinforcing ribs 1226 are formed in the annular space SP. A first hole 1228 is formed in the leading edge surface of the contact 122 to allow the end of the first terminal 1228 to protrude.

One end of the first terminal 128 is inserted into the contact 122 and protrudes on the front edge surface of the contact 122, i.e., on the inner wall of the annular space SP, and the other end of the first terminal 128 is capable of being connected to the first circuit board 2. In fig. 4d, the first terminal 128 further includes a first connecting portion 1282, an elastic portion 1284, and a first contact portion 1286 (i.e., the end of the first terminal 1228 protruding through the first opening 1228 as described in the previous paragraph). The elastic part 1284 is disposed between the first contact part 1286 and the first connection part 1282. The first contact portion 1286 can electrically contact the second contact portion 1466 of the second terminal 146 (shown in fig. 6 d) and the first connection portion 1282 can be connected to the first circuit board 2. It should be noted that the elastic portion 1284 is capable of receiving the pressure from the first contact portion 1286 to deform or the elastic portion 1284 provides the elastic force to push against the insertion surface IF of the insert, so that the insert can be stably disposed in the annular space SP.

The first fixing member 124 can be provided at the first circuit board 2. In the present embodiment, the number of the first fixing elements 124 is illustrated by taking 2 as an example. Referring to fig. 4b, the first fixing member 124 forms a floating space FSP receiving the extension block 1224. A gap is formed between the extension block 1224 and the inner wall of the first fixing member 124 to allow the extension block 1224 to float in the floating space accommodating FSP through the gap, and fig. 10a and 10b are combined to illustrate a space diagram of the extension block and the floating space of fig. 4a and 4b according to the present invention. Fig. 10a and 10b show that the extension block 1224 can move in the X-Y plane formed by the X-direction and the Y-direction of the drawing plane of fig. 3, so that the contact 122 has the effect of floating.

The housing 126 combines the contact 122 with the first fixing member 124, and refer to fig. 4 c.

In fig. 5, the male end 14 includes a first body 142, a second fixing member 144 and a second terminal 146.

The first body 142 is coupled to the second fixing member 144. The first body 142 is a C-shaped body and has an insert formed at a front edge, that is, a portion of the first body 142 that forms an insert surface IF formed at an outer surface of the insert. It is noted that the insertion face IF of the first body 142 is parallel to the front edge surface of the contact 122.

In an embodiment, after the insert is inserted into the annular space SP, the insert is spaced apart from the inner wall of the annular space SP formed by the contact 122 by a gap so that the insert can be smoothly inserted into the annular space SP, and fig. 9 is a plan view illustrating the insertion of the insert into the annular space of fig. 1. It should be noted that the annular space SP may form a chamfered structure for the insert to be inserted or slid into the annular space SP more smoothly.

In fig. 6a and 6b, the first body 142 further includes an opening 1422 and a second opening 1428. An opening 1422 is formed on both sides of the first body 142 to provide the second fixing member 144, and a second opening 1428 is formed on the insertion face IF to allow the end (a later-mentioned second contact portion 1466) of the second terminal 146 to protrude.

The first body 142 further includes a positioning groove 1424 formed in an outer surface of the insert. In another embodiment, the reinforcing ribs 1226 that engage the contact 122 are also described with reference to FIG. 4 a. The positioning groove 1424 is disposed corresponding to the reinforcing rib 1226, and the positioning groove 1424 is combined with the reinforcing rib 1226 to fix the insertion face IF in the annular space SP.

In fig. 6c, the first body 142 further includes a catch 1426 formed on an inner surface of the insert. In another embodiment, the annular space SP may form a groove (not shown), such that the fastening point 1426 is disposed corresponding to the groove, and after the inner surface of the insert contacts the annular space SP, the fastening point 1426 sinks into the groove to fasten the insert in the annular space SP, and referring to fig. 7, a cross-sectional view illustrating the fastening of the insert in the annular space of fig. 1 of the present invention is shown.

One end of the second terminal 146 is inserted into the first body 142 and is disposed along the insertion surface IF of the first body 142, and the other end of the second terminal 146 is connectable to the second circuit board 4. Fig. 6d is a schematic diagram illustrating the structure of the second terminal of fig. 5 according to the present invention. In fig. 6d, the second terminal 146 further has a second connection portion 1462 and a second contact portion 1466. The second connecting portion 1462 connects the second contact portions 1466. The second contact portion 1466 can electrically contact the first contact portion 1286 and the second connection portion 1462 connected to the second circuit board 4. Fig. 8 is a schematic diagram illustrating the connection between the first terminal 128 and the second terminal 146 according to the present invention, shown in fig. 1.

The second fixing member 144 can be provided at the second circuit board 4.

When the insertion surface IF of the first body 142 located above moves in a direction (for example, Y direction in fig. 2) toward the lower annular space SP, the insert of the first body 142 is inserted into the annular space SP, and the first contact portion 1286 of the first terminal 128 contacts the second contact portion 1466 of the second terminal 146, so that the first circuit board 2 and the second circuit board 4 can be electrically connected.

Although the present invention has been described with reference to particular embodiments, it will be understood by those skilled in the art that various changes in form, construction, features, methods and quantities may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
