1. Field of the Invention
The present invention relates to an electrical connector, and more particularly to a right-angled type electrical connector having two insulative retainers coordinating with each other so as to position a plurality of terminals therebetween.
2. Description of the Related Art
Japan Pat. No. 3366250 issued on Nov. 1, 2002, discloses an electrical connector. The connector includes an insulative housing, a plurality of contacts received in the insulative housing and a retaining spacer attached on the insulative housing. The insulative housing has a base portion and an engaging portion extending forward from the base portion. Each of the contacts defines a retaining portion held in the housing, a contacting portion extending from one end of the retaining portion into the engaging portion and a soldering tail integrally connected to another end of the retaining portion at a right angle. The retaining spacer includes a plurality of through-holes for receiving and positioning the soldering tails which extend through thereof. However, it is without the function of dust-proof because of absent of protecting measures for the contacts. Additionally, when the terminals are assembled with the retaining spacer, the soldering tails of the terminals will be deviated from their original position if they are pushed by the retaining spacer upwardly.
U.S. Pat. No. 6,860,744 issued to Maruyama et al. on Mar. 1, 2005, shows a low-profile connector having an insulative housing and a plurality of terminals parallel-arranged in the insulative housing. The insulative housing defines a base portion and an engaging portion extending from the base portion. Each of the terminals includes a soldering tail and a contacting portion connecting to the soldering tail and extending into the engaging portion for electrical connection with a mating connector. The terminal defines an intermediate crank-like portion and a right-angled connecting portion integrally connecting with the intermediate crank-like portion and the soldering tail. The right-angled connecting portion is pressed against by a protecting ceiling which unitarily extends from the base portion of the insulative housing for dustproof and preventing the terminals from overly-deflected. However, in such a manner that the structure of insulative housing is complicated and the terminal is unable to be easily assembled into the insulative housing.
Therefore, an improved electrical connector is desired to overcome the disadvantages of the related arts.
An object of the present invention is to provide an electrical connector having two insulative retainers in which the contacts can be readily and easily assembled onto a connector housing without encountering any disadvantages as well as laborious assembling process.
In order to achieve the above-mentioned object, an electrical connector in accordance with a preferred embodiment of the present invention includes an insulative housing with a base portion and an engaging portion extending from the base portion, a plurality of contacts which defines a retaining portion, a contacting portion extending from the retaining portion and a soldering portion extending outwards from the retaining portion and a first insulative retainer and a second insulative retainer opposite to each other and assembled in the insulative housing. The first insulative retainer has a plurality of through-holes receiving the soldering portion therein, while the second insulative retainer includes a plurality of recesses corresponding with the contacts which include a plurality of intermediate connecting portions received therein and interconnecting with the retaining portion and soldering portions unitarily.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description of the present embodiment when taken in conjunction with the accompanying drawings.
Reference will now be made to the drawing figures to describe the preferred embodiment of the present invention in detail.
Referring to
The engaging portion 12 of the insulative housing 1 defines three tongue plates (i.e. a first tongue plate 12a, a second tongue plate 12b and a third tongue plate 12c), thereby forming a first mating room 120 and a second mating room 121 for receiving a mating connector (not shown). The base portion has a recess 110 for receiving the second insulative retainer 5 therein. The second insulative retainer 5 is inserted into the recess 110 along the Y direction and defines a pair of blocking portions 51 engaged with an inner surface of the recess 110 for positioning thereof in the insulative housing 1 steadily. The insulative housing 1 includes a plurality of grooves 122 extending from the base portion into engaging portion 12 for receiving the contacts 2 respectively therein. The contacts 2 are inserted into the grooves 122, each of which includes a retaining portion 201 retained in the insulative housing 1, a contacting portion 202 extending from one end of the retaining portion 201 into the engaging portion 12, a soldering tail 203 extending from another end of the retaining portion 201 and a reverse L-shaped intermediate connecting portion 204 unitarily connecting with the soldering tail 203 and the retaining portion 201.
Referring to
The first insulative retainer 4 is assembled into the base portion 11 along a vertical direction (i.e. a Z direction) and blocked with the base portion 11, thereby forming an opposite relationship with the second insulative retainer 5 in the Z direction. The soldering tails 203 of the contacts 2 are also divided into four arrays in the Y direction and extending through the first insulative retainer 4 which defines a plurality of through-holes 41 for receiving and positioning the soldering tails 203.
