The present invention relates to an electrical connector and more particularly to a blade-type vehicle connector that is injection integrated forming and flexible for wiring application.
The electrical connector can be widely used to transmit electric current and signals in the electromechanical field. The commonly known blade-type achieves connection by combining male terminal in the from of blade with elastic female terminals, and each of individual blades is capable of independently transmitting different types of electrical signals.
However, the conventional electrical connector has following disadvantages: (i) in the connection and utilization of electricity, numerous adjustments are often required, and different demands may occur for the parameters of electricity or signals when used, such as varying voltage or phase differences, resulting in different expected outcomes upon power supply. Therefore, there remains a need for a new and improved design for an electrical connector to overcome the problems presented above.
The present invention provides a blade-type electrical connector comprising a male connecting member and a female connecting member. The male connecting member has a plurality of male terminal blades, and a first connecting head is integrally injection-molded to cover a portion of the male terminal blades. The male terminal blades are arranged into two rows, and each of the male terminal blades has a front end and a rear end respectively formed into a first connecting end and a second connecting end, and the male terminal blade comprises two locating recesses symmetrically concaved on the upper and lower edges of the male terminal blade. The first connecting head has a covering portion to securely connect to the male terminal blades, and the covering portion comprises a plurality of locating protrudes formed along the surface of the locating recess so that the first connecting ends and the second connecting ends respectively protrude from the front surface and the rear surface of the first connecting head. A first water-stop pad is coupled at the front end of the first connecting head, and a plurality of second through holes formed on the surface of the first water-stop pad are adapted to be respectively passed by the first connecting ends of the male terminal blades. A second water-stop pad is coupled with the rear surface of the first connecting head. The male connecting member is inserted and connected to the female connecting member, and the female connecting member comprises a plurality of gate-type female slots and a second connecting head, and the second connecting head is integrally injection-molded to connect to the female slots, and the female slots are arranged into two rows. Each of the female slots has a third connecting end and a fourth connecting end, and the second connecting head has a frame body. A horizontal partition and a plurality of vertical partitions are formed inside space of the frame body to evenly divide the inside space into a plurality of separated terminal chambers, and the number and positions of the terminal chambers are arranged corresponding to the female terminal slots. The third connecting ends of the female terminal slots are respectively accommodated in the terminal chambers, and two wiring areas are respectively formed on both of the upper and lower sides of the horizontal partition, and the distance of wiring area is less than one-third of the height of the terminal chamber. The fourth connecting end located within the wiring area protrudes from the rear end of the second connecting end. Each of the left end and the right end of the fourth connecting end has a protruded connecting edge, and the two protruded connecting edges are located symmetrically. A plurality of connecting slots are formed on the second connecting head along the protruded connecting edges in the injection process, and a connecting base is integrally formed on the edge of the second connecting head, and a third water-stop pad is coupled with the front end of the connecting base. Each of the male terminal blades and the female terminal slots are arranged into two rows, and each of the fourth connecting ends is connected to a connecting wire, and at least one connecting wire is connected to form a wire set so as to adjust the properties of the electricity according to the number and positions of the connected female connecting ends.
Comparing with conventional electrical connector, the present invention is advantageous because: (i) by organizing and arranging the wire sets to connect to the fourth connecting ends through the connecting wires, the male connecting member and the female connecting member are easily connected even when the number of the male terminal blades and the female terminal slots are high, and the voltage and phase of the electrical connector can be adjusted by connecting different quantities and arranges of the fourth connecting ends through the connecting wires; (ii) the distance of wiring area is less than one-third of the height of the terminal chamber, so that the vertical distance between the two rows of the fourth connecting ends is smaller, thereby facilitating the interconnection; (iii) the first water-stop pad, the second water-stop pad, and the third water-stop pad are adapted to enhance the waterproof capability of the electrical connector so as to ensure the connection quality between the male terminal blades and the female terminal slots; (iv) the first connecting head and the second connecting head formed from injection molding are respectively connected on the male terminal blades and the female terminal slots, and with the locating recesses and the locating protrudes, the male terminal blades are firmly secured with the first connecting head; and (v) with the protruded connecting edges and the connecting slots, the female terminal slots are firmly secured with the second connecting head, so as to enhance both the manufacturing efficiency and quality of the male connecting member and the female connecting member.
