The present disclosure relates to an electrical connector, and particularly to the electrical connector with the associated wires connected to the blade type contacts.
The convention cable connector discloses the inner conductors of the wires soldered upon the tails of the blade type contacts behind the rear face of the housing, and a waterproof glue plate is further applied into a rear receiving space of the housing to cover the rear face of the housing. Anyhow, for the wires extending in the vertical direction perpendicular to a horizontal direction along which the contacts extend, the peripheral wall formed by the housing surrounding the receiving cavity is required to form a plurality of passages for allowing the corresponding wires to extend along the vertical direction. Because such passages are aligned with the receiving space in the vertical direction, it may result in leakage during filling the waterproof glue in the receiving space, thus jeopardizing sealing thereabouts.
An improved connector is desired to provide the electrical cable connector with the good waterproofing function for the wires extending in the vertical direction perpendicular to the horizontal direction along which the contacts extend.
An object of the invention is to provide an electrical connector with an insulative housing, a plurality of passageways, a contact module including a plurality of blade type contacts retained to the retaining grooves in the corresponding passageways, a spacer located in a rear receiving space of the housing and behind the passageways for covering the passageways with corresponding slits through which tails of the contacts rearwardly extend, and a plurality of wires having the inner conductors soldered upon the tails of the contacts behind the spacer. A waterproof glue plate fills the receiving space of the housing to enclose the exposed inner conductors and the corresponding tails. A peripheral wall is formed on a rear side of the housing, and forms therein the aforementioned rear receiving space which further forwardly extends into the rear side of the housing with a distance so as to receive the spacer therein. A plurality of passages are formed in one side of the peripheral wall, through which the wires extend in a vertical direction perpendicular to the horizontal direction along which the contacts extend. The spacer forms a recess to receive a protrusion of the glue plate, and the protrusion is located adjacent to the passages for assuring sealing around said passages.
Other objects, advantages and novel features of the disclosure will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
Referring to
The housing 1 includes a base 11, a mating port 10 forwardly extending from the base 11, and the peripheral wall 12 rearwardly extending from the base 11 to form the rear portion of the rear receiving space 122. The mating port forms a horizontal mating face and a vertical mating face perpendicular to each other. The base 11 forms a pair of holes at two opposite transverse ends for installation of the corresponding screw nuts 105 therein. A plurality of dividers 13 are formed in the mating port 10 including a middle thicker one 131 and two opposite end walls 132. A bottom wall 133 is connected to the dividers 13 in the transverse direction. A plurality of slots 14 are formed between the corresponding dividers 13, respectively, to receive the corresponding contacts 3 and another blade type contact of the mated connector (not shown).
Referring to
The wires 4 are received within the corresponding passages 121, respectively, and include the power wires 4P corresponding to the power contacts 3P, and the signal wires 4S corresponding to the signal contacts 3S.
The glue plate 5 is formed in the receiving space 122 and behind the spacer 2 for covering the spacer 2, the tails 33 of the contacts 3 and the exposed inner conductors 41 and the front end region of the insulators 42 of the wires 4. In this embodiment, the glue plate 5 is further bulged beyond the receiving space 122 via a special mold optimally and optionally. The glue plate 5 further includes a protrusion 51 received within the recess 21 so as to enhance the mechanical strength and complete the waterproofing sealing around the passages 121, thus advantageously avoiding the possible cracking of the glue plate around the passages 121 compared with the earlier design in which no recess is formed in the spacer and no protrusion is formed on the glue plate to be retained in the recess around the passages through which the wires extend in a vertical direction perpendicular to the horizontal direction along which the contact extends.
As shown in
While a preferred embodiment in accordance with the present disclosure has been shown and described, equivalent modifications and changes known to persons skilled in the art according to the spirit of the present disclosure are considered within the scope of the present disclosure as described in the appended claims.
