Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, specifically to a non-circular electrical connector. Background Technology

[0002] Electrical connectors play a crucial role in the connection of electronic devices. Traditional electrical connectors typically employ standard circular or rectangular designs, which, while meeting basic connection requirements, present higher demands in certain specialized applications, such as aerospace and precision instruments, regarding the shape, stability, and contact area of ​​the connectors. However, traditional connector designs often suffer from limited contact area and insufficient stability after mating. These issues can lead to the connector becoming loose after mating and eventually detaching after prolonged use, thus affecting its usability. Utility Model Content

[0003] In order to overcome the shortcomings of existing technical solutions, this utility model provides an irregularly shaped electrical connector, which can effectively solve the technical problems of insufficient stability and easy loosening of current electrical connectors after mating.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A non-standard electrical connector includes a female connector and a male connector for mating connection. The female connector has a female housing, one end of which has an outer groove. A protrusion is coaxially arranged in the outer groove. The protrusion has a petal-shaped structure and is composed of at least three petals. A plurality of female terminals are installed in the protrusion. The number of female terminals is the same as the number of petals, and the female terminals are distributed in different petals. Each petal has a socket that is conductive to the corresponding female terminal.

[0006] The male connector has a male housing, one end of which has a plug that can be inserted into an outer groove. The plug has an inner groove that matches the protrusion. Several male terminals are installed in the inner groove. The number and position of the male terminals correspond to the female terminals, and each male terminal passes through the corresponding socket to connect with the female terminal.

[0007] The inner wall of the outer groove is provided with a limiting groove distributed circumferentially, and the outer side of the plug is provided with a limiting strip that matches the limiting groove. When the plug is fully inserted into the outer groove, the limiting strip is simultaneously inserted into the limiting groove to achieve the locking and fixing of the female connector and the male connector.

[0008] Furthermore, the inner wall of the outer groove is provided with a raised anti-foolproof block, and the outer side of the plug is provided with an anti-foolproof slot corresponding to the anti-foolproof block.

[0009] Furthermore, the opening edge of the inner groove is provided with an inclined surface, which gradually slopes towards the inner wall of the inner groove, so that the size of the inner groove gradually decreases.

[0010] Furthermore, the female component housing has a protruding female component extension at the end away from the outer groove, and the female terminal extends outward from the female component extension at the end away from the male connector;

[0011] The male component housing has a protruding male component extension at the end away from the plug, and the male terminal extends outward from the male component extension at the end away from the female connector.

[0012] Furthermore, both the outer shell of the female component and the outer shell of the male component are provided with anti-slip parts on their outer sides.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention employs a double-interlocking structure internally when the female and male connectors are mated, enhancing the stability of the connection. Furthermore, the mounting terminals utilize a petal-shaped structure, increasing the contact area during mating and improving the connection's robustness. Additionally, at the contact point between the female and male connectors, a self-locking structure is formed by a limiting strip and a limiting groove, eliminating the need for additional auxiliary locking components. This simplifies operation and improves the efficiency of the connection process. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1-5 As shown, this utility model provides an irregularly shaped electrical connector, mainly used for electrical conduction and signal transmission after mating connection. The structure of this irregularly shaped connector mainly includes two parts: a female connector 1 and a male connector 2 for mating connection. In use, the female connector 1 and the male connector 2 are mated together.

[0027] Both the female connector 1 and the male connector 2 are provided with outer shells to protect their internal structures. Specifically, the female connector 1 has a female outer shell 101, and the male connector 2 has a male outer shell 201. To enable a mating connection between the female connector 1 and the male connector 2, one end of the female outer shell 101 has an outer groove 102, within which a coaxially arranged protrusion 103 is located. Correspondingly, one end of the male outer shell 201 has a plug 202 that can be inserted into the outer groove 102. The plug 202 has an inner groove 203 that matches the protrusion 103. Thus, a double mating connection structure is formed during the mating connection, which helps improve the stability of the connection. Furthermore, in this technical solution, the protrusion 103 has a petal-shaped structure composed of four petals 1031. This structure increases the contact area after mating, improving the reliability and stability of the connection.

[0028] The terminals used for connection and conduction include four female terminals 3 and four male terminals 4. The four female terminals 3 are installed within the protrusion 103, and each female terminal 3 is installed inside a different segment 1031. Each segment 1031 has one female terminal 3, and a prong 104 for communication with the female terminal 3 is provided on the segment 1031 to facilitate insertion and connection of the male terminals 4. Correspondingly, the four male terminals 4 are installed within the recess 203, and the positions of the male terminals 4 correspond to those of the female terminals 3. During connection, the male terminals 4 pass through the prong 104 to contact and conduct electricity with the corresponding female terminal 3.

[0029] After the female connector 1 and male connector 2 are plugged together, a self-locking effect is achieved through the internal structure. At one end of the female connector 1, the inner wall of the outer groove 102 is provided with a circumferentially distributed limiting groove 105, while at one end of the male connector 2, the outer side of the plug 202 is provided with a limiting strip 204 that matches the limiting groove 105. During operation, when the plug 202 is fully inserted into the outer groove 102, the limiting strip 204 simultaneously engages with the limiting groove 105, thereby locking the female connector 1 and male connector 2 together and completing the self-locking structure. No other accessories are required for fixation, simplifying the operation.

[0030] To ensure the correct direction during insertion, a foolproof structure is provided on the contact surfaces of the female connector 1 and the male connector 2. Specifically, the foolproof structure consists of a raised foolproof block 106 on the inner wall of the outer groove 102 and a foolproof slot 205 on the outer side of the plug 202 that corresponds to the foolproof block 106. This structure ensures the uniqueness of the insertion direction, avoids damage to the terminals caused by blind insertion, and improves service life.

[0031] In addition, in order to facilitate the quick insertion of the protrusion 103 into the inner groove 203, an inclined surface 206 is provided at the edge of the opening of the inner groove 203. The inclined surface 206 gradually slopes towards the inner wall of the inner groove 203, so that the inner groove 203 gradually becomes smaller from the opening to the bottom. In this way, when connecting, the protrusion 103 will slide down along the inclined surface 206 into the inner groove 203.

[0032] Anti-slip parts 5 are provided on the outer sides of both the female housing 101 and the male housing 201 to increase the surface friction and facilitate user plugging and unplugging connections.

[0033] The female terminal 3 and male terminal 4 extend outward from the end of the housing away from the insertion point. Specifically, the female housing 101 has a raised female extension 107 at the end away from the outer groove 102, and the female terminal 3 extends outward from the female extension 107 at the end away from the male connector 2; the male housing 201 has a raised male extension 207 at the end away from the plug 202, and the male terminal 4 extends outward from the male extension 207 at the end away from the female connector 1.

[0034] Compared with traditional technologies, this technical solution employs a double-interlocking structure when the female connector 1 and male connector 2 are mated, enhancing the stability of the connection. Furthermore, the petal-shaped structure at the terminal mounting position increases the contact area during mating, improving the connection's robustness. Additionally, at the contact point between the female connector 1 and male connector 2, a self-locking structure is formed by the limiting strip 204 and the limiting groove 105, eliminating the need for additional auxiliary locking components. This simplifies operation and improves the efficiency of the connection process.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
