Technical Field

[0001] This application relates to the field of connector product technology, and in particular to a PIN connector. Background Technology

[0002] In related technologies, automotive connectors are devices used in automotive electronic systems to detachably connect two circuit conductors. They establish a reliable, safe, and detachable electrical signal and power transmission channel between core electrical components (such as ECUs, sensors, and actuators) and wiring harnesses, or between wiring harnesses themselves. Simply put, they are "standardized bridges and junctions" in the complex circuit network of a car, ensuring that electrical energy and signals can flow efficiently and stably between different components. Automotive connectors are high-tech components integrating electrical engineering, materials science, mechanical structure, and environmental engineering. They are fundamental and crucial to ensuring the realization of all functions in modern automobiles, especially electrified and intelligent vehicles. Without high-performance connectors, today's highly complex and reliable automotive electronic systems would not exist.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0023] The following is for reference. Figures 1 to 3 This invention describes a PIN connector according to an embodiment of the present invention.

[0024] like Figures 1 to 2 As shown, the PIN connector according to an embodiment of the present invention includes: a core body 100 and a terminal assembly 200. The core body 100 is provided with a receiving groove 110. The terminal assembly 200 includes a terminal group 210 and a core seat 220. The terminal group 210 includes a plurality of terminals 211. The core seat 220 is provided with a plurality of positioning holes 222 for fixing the terminals 211. The terminal assembly 200 is inserted into the core body 100 through the receiving groove 110.

[0025] It is understood that this PIN connector includes a terminal assembly 200 and a core body 100 wrapped around the terminal assembly 200. The terminal assembly 200 passes through the receiving groove 110 of the core body 100 and includes a terminal group 210 and a core seat 220. Multiple terminals 211 of the terminal group 210 are respectively fixed to multiple positioning holes 222 of the core seat 220, thereby positioning and fixing the terminal group 210 through the core seat 220. Then, the core body 100 is injection molded together with the terminal group 210 and the core seat 220. This avoids the situation of misalignment and scratches to the plating during the placement of the terminals 211, thereby improving the processing quality of the PIN connector and thus improving the product yield of the PIN connector.

[0026] It is understood that the upper and lower end faces of the core body 100 are respectively provided with a plurality of material removal holes 120, the material removal holes 120 avoiding the receiving groove 110, and penetrating the upper or lower end face of the core body 100. For example, as Figure 1 As shown, in this embodiment, by providing material removal holes 120 that avoid the receiving groove 110 on the upper and lower end faces of the core body 100, the temperature difference between the material near the geometric center of the core body 100 and the outer surface of the core body 100 can be reduced during the thermal expansion and contraction process after injection molding, thereby improving the shrinkage of the core body 100 after injection molding and also improving the sticking to the mold.

[0027] It is understood that the adhesive core holder 220 is provided with at least two sets, and each set is sleeved on the terminal 211 along the length direction of the terminal 211. For example, as Figures 1 to 2 As shown, in this embodiment, by providing at least two sets of adhesive core holders 220 along the length of the terminal 211, the terminal 211 is better positioned and fixed, thus improving the situation of terminal 211 displacement. In other embodiments, more than two adhesive core holders 220 may be provided.

[0028] It is understandable that the core holder 220 and the terminal 211 are interference-fitted. For example, as Figure 2As shown, in this embodiment, the core holder 220 and the terminal 211 are interference-fitted, thereby achieving the positioning and fixation of the core holder 220 and the terminal 211. In other embodiments, other positioning methods can be used to fix the terminal 211, such as anti-slip textures.

[0029] It is understood that terminal 211 is in a bent shape, and terminal 211 includes a first straight portion 2111, a second straight portion 2112, and a bent portion 2113. The bent portion 2113 connects the first straight portion 2111 and the second straight portion 2112, and the first straight portion 2111 and the second straight portion 2112 are perpendicular to each other. For example, as... Figure 2 As shown, in this embodiment, the terminal 211 includes a first straight portion 2111, a bent portion 2113, and a second straight portion 2112 connected in sequence, with the first straight portion 2111 and the second straight portion 2112 being perpendicular to each other.

[0030] It is understandable that the bending portion 2113 is located inside the core body 100. For example, as... Figures 1 to 2 As shown, in this embodiment, the terminal 211 is positioned and further fixed by injection molding the bent portion 2113 into the interior of the core body 100.

[0031] It is understandable that the bend 2113 is arc-shaped. For example, as... Figures 1 to 2 As shown, in this embodiment, the arc-shaped bend 2113 can provide stress relief and protect the root of the terminal 211.

[0032] It is understood that the positioning hole 222 penetrates the front and rear of the core holder 220, and the upper wall of the core holder 220 extends forward and backward to form upper protruding edges 223 protruding from the positioning hole 222, respectively. The lower wall of the core holder 220 extends forward and backward to form lower protruding edges 224 protruding from the positioning hole 222, respectively. For example, as... Figures 2 to 3 As shown, in this embodiment, the positioning hole 222 passes through the front and rear of the core seat 220, and an upper protruding edge 223 and a lower protruding edge 224 are formed at the front end of the positioning hole 222 in the core seat 220, and an upper protruding edge 223 and a lower protruding edge 224 are also formed at the rear end of the positioning hole 222. This structural design enables the core seat 220 to be more firmly located inside the core body 100 after injection molding, improving the connection strength and preventing loosening.

[0033] It is understood that the adhesive core holder 220 includes a plurality of adhesive core units 221 connected in sequence, and the adhesive core units 221 are arranged in a one-to-one correspondence with the terminals 211. For example, as Figures 2 to 3As shown, in this embodiment, the glue core holder 220 includes a plurality of interconnected glue core units 221. The glue core units 221 connected one by one can respectively position a single terminal 211, and the structure of the plurality of interconnected glue core units 221 allows the raw material of the glue core holder 220 to be easily cut into the required number of glue core units 221 as needed.

[0034] It is understood that the port of the positioning hole 222 is provided with a guide surface 225 connecting the end face and inner side of the adhesive core seat 220. The guide surface 225 is inclined from the outside to the inside to facilitate the insertion of the terminal 211. For example, as Figures 2 to 3 As shown, in this embodiment, a guide surface 225 is provided at the port of the positioning hole 222 to connect the end face and the inner side of the glue core seat 220, thereby facilitating the insertion of the terminal 211.

[0035] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
