DETAILED DESCRIPTION OF THE EMBODIMENT(S)
Exemplary embodiments of the present disclosure will be described hereinafter in detail with reference to the attached drawings, wherein the like reference numerals refer to the like elements. The present disclosure may, however, be embodied in many different forms and should not be construed as being limited to the embodiment set forth herein; rather, these embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the concept of the disclosure to those skilled in the art.
Now with reference to FIGS. 1-6, a connector 100 according to the invention will be described
As shown in FIGS. 1-4, the connector 100 generally includes a contact receiving housing 1 and a contact 2 inserted into the contact receiving housing 1.
In the shown embodiment, the contact receiving housing 1 is u-shaped and includes a bottom wall 11 and two side walls 12 that extend upward from two opposite sides of the bottom wall 11. The bottom wall 11 and the side walls 12 define a receiving space for receiving the contact 2.
In the shown embodiment, the contact 2 is made from a conductive material. The contact 2 generally includes including a frame 20 defined by a top wall 203, a pair of side walls 202, a bottom wall 201, and a terminal section 21 that extends from the front end of the frame 20.
As is clearly shown in FIGS. 2 and 4, an insertion member 13 is provided and extends from one end of the bottom wall 11. The insertion member 13 is separated from and extends between the pair of side walls 12. In use, the insertion member 13 is adapted to be inserted inside the frame 20 of the contact 2 and to abut on an inner surface of the bottom wall 201 of the frame 20. In this state, the contact 2 is fitted over the insertion member 13 and positioned in the receiving space of the housing 1.
The connector 100 further comprises a securing device 130 configured to securely connect the insertion member 13 and the bottom wall 201 of the frame 20 onto a mounting plate 200 (referring to FIGS. 6 and 7). The securing device 130 is positioned inside the housing 1.
Because the securing device 130 is positioned inside the housing 1 of the connector 100, there is no need to provide an additional space on the mounting plate 200 for the securing device 130. As a result, the mounting space on the mounting plate 200 can be saved.
As shown in FIGS. 1-4, according to an embodiment, the securing device 130 includes a first hole 131 formed in the insertion member 13, a screw nut 132 integrally formed on the insertion member 13 at the first hole 131, and a second hole 231 formed in the bottom wall 201 of the frame 20 of the contact 2. When the contact 2 is inserted into the receiving space of the housing 1, the first hole 131 aligns with the second hole 231. As a result, as shown in FIG. 7, a screw bolt 133 can pass through a mounting hole (not shown) on a mounting plate 200, the second hole 231 and the first hole 131 in this order and be secured on the screw nut 132, so that the connector 100 is securely connected to the mounting plate 200.
According the above embodiment, since the screw nut 132 is preset on the connector 100, when the connector 100 is mounted to the mounting plate 200, it is not necessary to mount the screw nut 132 on site. Thus, the connector 100 can be mounted conveniently and the mounting time can be reduced.
According to an embodiment of the invention, the screw nut 132 is a self-locking nut which is pressed and connected integrally on the inner surface of the insertion member 13 of the housing 1 during the process of manufacturing the connector 100. Therefore, the screw nut 132 is securely connected to the insertion member 13 and it is not necessary to pierce a hole in the insertion member 13 while the connector 100 is mounted, thus, it is not necessary to pierce a hole in the thinner insertion member 13.
As shown in FIGS. 1-4, according to an embodiment of the invention, the first hole 131, the second hole 231 and the screw nut 132 are positioned along a longitudinal central line L of the bottom wall 11 of the housing 1. Thus, when the connector 100 is secured to the mounting plate 200, as shown in FIGS. 6 and 7, by the screw nut 132, the connector 100 can be securely mounted to the mounting plate 200 as compared with the case where a fastener nut is positioned in other places.
In the embodiment shown, the connector 100 includes two first holes 131, two second holes 231 and two screw nuts 132, respectively. With this configuration, it is easy to mount the contact 2 on the central line of the bottom wall 11 of the housing 1. However, it should note that the numbers of the first holes 131, the second holes 231 and the screw nuts 132 are not limited to what is shown. Rather, one skilled in the art should appreciate that other design configurations are possible.
As shown in FIG. 2, each side wall 12 include a first side wall section 12a connected with the bottom wall 11 and a second side wall section 12b that is separated from the bottom wall 11 and positioned to correspond with the insertion member 13. A vertical slit 12c is formed between the first side wall section 12a and the second side wall section 12b. 
As shown in FIGS. 1-4, a lower portion 20b of each of the second side wall sections 12b of the housing 1 flares outward so that the contact 2 can be easily inserted into the housing 1 and will not shake in a left and right direction. As a result, the first side wall section 12a serves as a stopping and positioning member for stopping further movement of the frame 20 of the contact 2 when the contact 2 is inserted.
As shown in FIGS. 1 and 3, when the contact 2 is inserted into the receiving space of the housing 1, the terminal section 21 of the contact 2 is positioned between the first side wall sections 12a of the housing 1, and the frame 20 of the contact 2 is positioned between the second side wall sections 12b of the housing 1. For this purpose, the connector 100 is manufactured so that a length of the second side wall section 12b or the insertion member 13 is approximately equal to the length of the frame 20, and a length of the first side wall section 12a of the housing 1 is approximately equal to a length of the terminal section 21 of the contact 2.
As is clearly shown in FIG. 2, each side wall 12 includes a first catch 121, while each side wall 202 includes a second catch 221 that corresponds with the first catch 121. As shown in FIGS. 1 and 3, the first catch 121 engages with the second catch 221 when the contact 2 is inserted in the receiving space of the housing 1. Specifically, according to this embodiment, the first catch 121 is a rectangular opening formed in each side wall 12 of the housing 1 at the second side wall section 12b, and the second catch 221 is an elastic projection extending outward from each side wall 202. The elastic projection may be formed by cutting a portion of each side wall 202 of the frame 20 and bending the cut portion.
When the contact 2 is inserted into the receiving space of the housing 1, the elastic projections on the frame 20 make contact with inner surfaces of the side walls 12 of the housing 1 so that the contact 2 can be securely inserted. As the contact 2 is inserted continuously, the elastic projections on the frame 20 enter the respective openings in the side walls 12 of the housing 1. Therefore, the elastic projections may assist to position and secure the contact 2 and the housing 1. The elastic projection may be positioned slantwise in a direction opposite to a direction for inserting the contact 2 into the housing 1. In this way, once the elastic projections enter the respective openings in the side walls 12 of the housing 1, the elastic projections can prevent the contact 2 from removal with from the housing 1 in an opposite direction.
Besides the first catch 121 and the second catch 221 in the above forms, a person skilled in the art can conceive of engaging devices in other forms, such as other known projections and a recesses, or other known mechanically movement resisting or arresting designs.
As is clearly shown in FIGS. 3 and 4, a U-shaped cutout 110 is formed at an end of the bottom wall 11 of the housing 1 opposite to the insertion member 13 for guiding and inserting a bus bar 300 (as shown in FIGS. 6 and 7). Further, the bottom of the U-shaped cutout 110 is used as a stopping and positioning part when the bus bar 300 is inserted. Preferably, the two sides of the opening part of the U-shaped cutout 110 are chamfered so as to guide and insert the bus bar 300 better.
Each of top ends of the first side wall sections 12a are bent inward, in the shown embodiment, in order to form an elongated opening 111 aligning with the U-shaped cutout 110 to guide and insert the bus bar 300.
As shown in FIG. 2, the frame 20 includes a narrow upper portion 20a and a wide lower portion 20b such that the upper portion 20a is positioned with respect to a substantial center of the lower portion 20b. Accordingly, the frame 20 has a cross section of a generally “” or t-shape. The terminal section 21 extends from a front end of the upper portion 20a. The lower portion 20b is adapted to fit over the insertion member 13 of the housing 1. The lower portion 20b has a width approximately equal to that of the housing 1.
As shown in FIGS. 2 and 5, the terminal section 21 includes two rows of terminals extending from the two side walls 202 of the frame 20 along the upper portion 20a thereof. The first row of terminals consists of a plurality of first terminals 21a. The second row of terminals consists of a plurality of second terminals 21b. Each terminal 21a, 21b is of an elongated bar shape and is bent into a generally S-shape in the embodiment shown. Alternatively, each terminal may have other shapes which are adapted to facilitate connection with an electric bus bar 300. In use, the bus bar 300 shown in FIG. 7 is inserted between the two rows of terminals from a front end thereof and is elastically clamped between the two rows of the terminals.
Further, as shown in FIG. 5, the first terminals 21a and the second terminals 21b are interleaved with each other between the two rows of terminals. By this arrangement of the terminals, the connector 100 can be ensured to have a low contact resistance.
The housing 1 and the contact 2 of the connector 100 according to an embodiment of the invention can be separately manufactured, and then are assembled together in the way as described above. The housing 1 and the contact 2 each can be manufactured from a single plate of metal by normal cutting, punching, molding or other processes.
As shown in FIGS. 6 and 7, a connector 100 according to the invention is secured on the mounting plate 200 by the following steps. First, the connector 100 is positioned on a mounting surface of the mounting plate 200 with a mounting hole formed in advance there through. The bottom wall 201 is in contact with the mounting surface of the mounting plate 200 and the second hole 231 in the bottom wall 201 of the frame 20 and the first hole 131 in the insertion member 13 of the housing 1 align with the mounting hole in the mounting plate 200. Next, a screw bolt 133 is inserted through the mounting hole of the mounting plate 200 from a bottom surface of the mounting plate 200 opposite to the mounting surface, and causing the screw bolt 133 to engage the screw nut 132 at the first hole 131 so that the connector 100 is secured on the mounting plate 200. At this time, the front portion of the housing 1 is projected beyond the front edge of the mounting plate 200 so as to facilitate the inserting of the electric bus bar 300. Then the bus bar 300 is inserted between the two rows of terminals 21a and 21b of the contact 2 from the front side of the housing 1 through the U-shaped cutout 110 and the top elongated opening 111 of the contact receiving housing 1, and thus the connection and mounting of the connector 100 is finished. In this state, when a power is applied, the power can be transmitted to the mounting plate 200 from the bus bar 300 through the contact 2 of the connector 100.
