Electrical connector with reliable terminal position

[0001] 1. Field of the Invention

[0002] The present invention relates to an electrical connector, especially to an electrical connector with terminals secured in an insulative housing reliably.

[0003] 2. Description of Related Art

[0004] Digital Still Camera, Cell phone and other portable devices are widely used today. Those devices all have a battery for powering. Thus an electrical connector is used for connecting the battery and corresponding element is required.

[0005] For example, U.S. Pat. No. 7,118,424 issued on Oct. 10, 2006 to Masaki et al. introduces an electrical connector for power transmitting. The electrical connector includes an insulative housing, a plurality of terminals mounted to the insulative housing. There are plurality of terminal slots defined in the insulative housing to receive the terminals, respectively. The terminal has a body portion, a connecting portion rearwardly extending from the body portion, and a contacting portion extending forwardly from the body portion and then bent backwardly from a front end thereof. There is a longitudinal slot defined in the mating portion. However, the terminal may sway in the terminal slot, when it is dragged by a cable which is terminated to the connecting portion thereof.

[0006] Hence, an improved electrical connector is required to overcome the problems of the prior art.

[0007] An object of the present invention is to provide an electrical connector with terminals being positioned in an insulative housing reliably.

[0008] Accordingly, to achieve above-mentioned object, an electrical connector comprises an insulative housing having a top wall and a bottom wall opposite to each other, at least one terminal slot located between the top wall and the bottom wall; a corresponding terminal received in the terminal slot, and the terminal having a body portion, a connecting portion extending backwardly from the body portion and a contacting portion extending forwardly from the body portion, the contacting portion defining a positioning slot; and wherein there is a positioning member located in the terminal slot and extending into the positioning slot.

[0009] The detailed features of the present invention will be apparent in the detailed description with appropriate reference to the accompanying drawings.

[0016] Reference will now be made in detail to the preferred embodiment of the present invention.

[0017] Referring to FIGS. 1-6, an electrical connector 100 in accordance with the present invention includes an insulative housing 1 and a number of terminals 2 received in the insulative housing 1.

[0018] The insulative housing 1 defines a front mating face 13, a top wall 11 and a bottom wall 12 opposite to each other. The insulative housing 1 further defines a number of terminal slots 10 disposed between the top and bottom walls 11, 12, arranged in one row along a transversal direction and through the front mating face 13. The terminals 2 are respectively accommodated in the terminal slots 10.

[0019] Each terminal 2 is stamped by a metallic sheet and has a body portion 20, a connecting portion 22 extending backwardly from the body portion 20 and a U-shaped contacting portion 29 extending forwardly from the body portion 20. The contacting portion 29 includes a first extending segment 21 connected to the body portion 20 and located at a first horizontal plane, an intermediate portion 291 extending downwardly from a front end of the first extending segment 21, and a second extending segment 23 located at a second horizontal plane which is under the first horizontal plane. The second extending segment 23 extending backwardly from a lower point of the intermediate portion 291. A longitudinal slot 25 is defined on the first extending segment 21, and two protrusions 26 are formed on the first extending segment 21 and extend into the longitudinal slot 25 from opposite sides thereof. There is hooking portion 24 formed at a back end of the second extending segment 23 and projects downwardly therefrom. The hooking portion 24 is locked into a transversal passage 120 which is located in the bottom wall 12 of the insulative housing 1. Hence, the terminal 2 can not move freely in the terminal slot 10 along the longitudinal direction. In addition, there is a positioning slot 28 defined in the second extending segment 23 and further through the intermediate portion 291. The positioning slot 28 has two lateral edges 291 which are defined on the second extending segment 23 and parallel to each other. There is a tab 27 formed on a top side of the body portion 27. The tab 27 is engaged with a corresponding positioning cavity 110 which is located in the top wall 11. The connecting portion 22 has a first connecting portion 220 connected to the body portion 20 and a second connecting portion 221 connected to the first connecting portion 220 and disposed behind the first connecting portion 220. The first connecting portion 220 is crimped to an inner conductor of a corresponding wire (not shown), and the second connecting portion 221 is crimped to an insulative jacket of the corresponding wire. The is a positioning member 121 formed on inner surface of the bottom wall 12 in each terminal slots 10. As the contacting portion 21 is configured to be U-shaped and resiliently engaged with the terminal slot 10, compressed by the by the top wall 11 and the bottom wall 12, and the positioning member 121 extends into the positioning slot 28 and is against lateral edges 290 of the positioning slot 28 to prevent the terminal 2 moving along the transversal direction.

[0020] While a preferred embodiment in accordance with the present invention has been shown and described, equivalent modifications and changes known to persons skilled in the art according to the spirit of the present invention are considered within the scope of the present invention as described in the appended claims.
