Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical connection device technology, and in particular to a connector used in electronic and electrical equipment. Background Technology
[0002] Many electronic and electrical devices rely on connectors for electrical connections to enable power transmission or signal handling. For example, automotive components like air conditioning compressors require connectors with a circular (square or round) housing containing multiple female terminals (female terminals). These terminals form a mating channel. The male terminals of the male connector are typically cylindrical. After being inserted into the mating channel of the female connector, the male terminal makes contact with each female terminal to achieve an electrical connection. However, because the male terminal is cylindrical, after insertion into the female connector, each female terminal typically only forms a single-line contact with the male terminal; that is, the contact area between the male and female terminals forms a straight line. This significantly affects the reliability of the electrical connection, resulting in poor current carrying capacity. It also leads to poor mating tolerance between connectors, causing inconvenience in use. Utility Model Content
[0003] This invention addresses the shortcomings of existing technologies by providing a terminal slotted connector that features a simpler structure, more rational design, more stable mating, higher current carrying capacity, and better mating tolerance.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a terminal slotted connector, comprising a housing and a plurality of female terminals disposed within the housing, wherein each female terminal forms a insertion channel for inserting a male terminal, characterized in that: the female terminals are bent into the housing from the top of the housing, and each female terminal extends into the housing at an incline so that the insertion channel forms a structure in which the internal size is smaller than the inlet size; each female terminal has a slot opened along its longitudinal direction, and the two sides of the slot are straight edges so that the male terminal contacts the two sides of the slot simultaneously after insertion.
[0005] Furthermore, each female terminal is connected to the housing via a curved arm. The curved arm extends from the head edge of the housing and bends in an arc towards the inside of the housing, giving the female terminal an elastic structure. The curved arm, the female terminal, and the housing are an integral structure.
[0006] Furthermore, a bending head is provided at the end of the female terminal. The bending head bends outward and abuts against the inner wall of the housing to form an elastic rebound structure for the female terminal. The bending head, the female terminal, and the housing are an integral structure.
[0007] Preferably, the housing is square-shaped with openings at both the front and rear ends to form a transparent structure; a female terminal is provided along each of the four side walls of the housing, and the four female terminals form a centrally symmetrical structure.
[0008] Furthermore, a rearwardly extending fixing foot is provided at the tail end of the housing, and a buckle is provided on the outer side wall of the fixing foot, which is locked and fixed to the carrier of the connector by the buckle.
[0009] Preferably, the buckle and fixing foot are integral with the housing.
[0010] This invention features multiple inclined female terminals within the housing, forming a connection channel with an entrance size larger than the internal dimensions. Each female terminal also has a longitudinally spaced slot. When a cylindrical male terminal is inserted into the connection channel, it simultaneously contacts both sides of the slot on the female terminal, achieving double-line contact with each female terminal. This doubles the contact area, thus doubling the current carrying capacity to over 40A. Furthermore, the stability and tolerance of the connection are improved, reaching a tolerance of 0.6mm.

[0016] In this embodiment, refer to Figures 1-4 The terminal slotted connector includes a housing 1 and a plurality of female terminals 2 disposed within the housing 1. Each female terminal 2 forms a mating channel for inserting a male terminal. The female terminals 2 are bent into the housing 1 from the top of the housing 1. Each female terminal 2 extends into the housing 1 at an angle so that the mating channel forms a structure with an internal size smaller than the entrance size, similar to a flared shape. Each female terminal 2 has a slot 21 opened along its longitudinal direction. The two sides of the slot 21 are straight edges so that the male terminal can contact the two sides of the slot 21 simultaneously after insertion. This results in two contact lines between each female terminal 2 and the male terminal, thereby doubling the current carrying capacity.
[0017] Each female terminal 2 is connected to the housing 1 by a curved arm 3. The curved arm 3 extends from the head edge of the housing 1 and bends in an arc towards the inside of the housing 1, thereby making the female terminal 2 have an elastic structure so that the male terminal can be clamped more tightly. The curved arm 3, the female terminal 2 and the housing 1 are an integral structure and are made by stamping.
[0018] A bending head 4 is provided at the end of the female terminal 2. The bending head 4 bends outward and abuts against the inner wall of the housing 1 to form an elastic rebound structure for the female terminal 2. When the male terminal is inserted, it will squeeze the female terminal 2 outward, and the bending head 4 will provide an inward reaction force to the female terminal 2 under the reaction force of the housing 1, thereby further clamping the male terminal and improving the stability of the insertion. The bending head 4, the female terminal 2 and the housing 1 are an integral structure and are also formed by stamping.
[0019] The housing 1 is square in shape, with openings at both the front and rear ends to form a transparent structure; a female terminal 2 is provided along each of the four side walls of the housing 1, and the four female terminals 2 form a centrally symmetrical structure.
[0020] A rearwardly extending fixing foot 5 is provided at the tail end of the housing 1, and a buckle 6 is provided on the outer wall of the fixing foot 5. The buckle 6 is used to lock and fix the connector to the carrier. For example, after the connector is injection molded into the plastic housing, the buckle 6 will be embedded in the plastic housing, thereby improving stability.
[0021] The buckle 6 and the fixing foot 5 are integral with the housing 1.
[0022] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of this application should still fall within the scope of the present invention.
