Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of electrical shock-absorbing connections, and in particular relates to a connector male head and an electrical connector with a shock-absorbing and quick-returning function. Background Art
[0002] In the field of electrical connections, connectors are key components for achieving circuit continuity, and their stability and durability directly impact the operating efficiency of the entire electrical system. Currently, the male connectors of commercially available connectors often require a spring-loaded reset mechanism to ensure accurate insertion the next time they are plugged in and out of the female connector.
[0003] In existing technology, the reset mechanism for male connectors often uses elastic silicone or ordinary cylindrical springs. However, when the male connector is subjected to significant impact (such as the instantaneous force during insertion or removal, or sustained external force in a vibrating environment), the elastic silicone can easily become permanently deformed due to excessive compression, causing the reset function to fail. While ordinary cylindrical springs can provide a certain degree of elastic support, they are prone to elastic attenuation after long-term, high-frequency use. Furthermore, the force-bearing areas at both ends are uneven, making it easy for them to cause jamming during the reset process due to unbalanced force, and even cause the male connector and female connector to become stuck, affecting the connector's service life and connection reliability.
[0004] Furthermore, traditional reset mechanisms have poor guidance, making it difficult to achieve stable feedback during insertion and removal, and prone to insertion offset, further exacerbating the reset jamming problem. Therefore, designing a male connector that can achieve fast and accurate reset while effectively resisting impact and preventing jamming or blocking has become a pressing technical challenge in this field.

[0047] Working principle of the male connector with shock-absorbing quick return function 1
[0048] 1. Insertion force and spring deformation
[0049] When the male connector 1 is plugged into the female connector 2, the female connector 2 generates an upward thrust on the pin 122, guide post 123, and electrode post 124, driving the plug portion 12 to move upward along the first inner cavity of the first shell 13. At this time, the first tapered hole 1211 on the pressure plate 121 of the plug portion 12 and the first limiting post 1212 squeeze the small end of the conical spring 14. Simultaneously, the first tapered post 112 in the first limiting hole 111 of the upper cover 11 restrains the large end of the conical spring 14, compressing the conical spring 14 axially and converting the external force into elastic potential energy.
[0050] 2. Shock absorption and buffering process
[0051] The large end of the conical spring 14 is matched with the first limiting hole 111, and the small end is matched with the first conical hole 1211, and the gradual force characteristics of the conical structure are used to disperse the impact:
[0052] During initial compression, the large end has a large contact area, quickly absorbing most of the plugging and unplugging impact force;
[0053] In the later stage of compression, the small end is further buffered by the tapered surface of the first tapered hole 1211 to reduce rigid collision.
[0054] At the same time, the inserting plate 125 and the first movable cavity 15 on the side of the first shell 13 provide a lateral movable space. During the process, the conical spring 14 offsets the lateral offset force to avoid jamming.
[0055] 3. Quick return mechanism
[0056] After the external plugging and unplugging force disappears, the conical spring 14 releases its elastic potential energy, pushing the plug-in portion 12 back downward:
[0057] The large end of the conical spring 14 extends along the first conical column 112, and the small end extends along the first limiting column 1212. The position is automatically corrected through the conical guide to ensure that the electrode column 124, the guide column 123 and the pin 122 return to their original positions accurately.
[0058] The limiting steps on the plug plate 125 cooperate with the limiting bosses of the electrode column 124, the guide column 123, and the plug pin 122 to prevent the components from loosening; the pressing connection between the pressure plate 121 and the plug plate 125 ensures the synchronous movement of all components.
[0059] Example 2
[0060] like Figures 5 to 7 As shown, an electrical connector includes a female socket 2 and the above-mentioned male connector 1 with shock-absorbing and quick-return function; the female socket 2 is connected to the male connector 1 with shock-absorbing and quick-return function.
[0061] Furthermore, the female socket 2 includes a second shell 21 and a bottom cover 24; the second shell 21 is respectively provided with an electrode column socket 212, a guide column socket 211 and a pin socket 213 corresponding to the electrode column 124, the guide column 123 and the pin 122; the electrode column socket 212 is provided with an electrode column socket 23; the pin socket 213 is provided with a pin socket 22; the bottom cover 24 is installed at the bottom of the second shell 21 by bolts or screws and is fixedly connected to the electrode column socket 23 and the pin socket 22, that is, the electrode column socket 23 and the pin socket 22 are limited and fixed so that the electrode column socket 23 and the pin socket 22 are firmly installed in the electrode column socket 212 and the pin socket 213.
[0062] Furthermore, the electrode post socket 212 includes a first electrode post socket 2121 and a second electrode post socket 2122, wherein there are two second electrode post sockets 2122, one located symmetrically on either side of the first electrode post socket 2121. The guide post socket 211 includes a first guide post socket 2111 and a second guide post socket 2112. The pin socket 213 includes a first group of pin sockets 2131 and a second group of pin sockets 2132. The first guide post socket 2111 and the second guide post socket 2112 are symmetrically arranged around the first electrode post socket 2121. The first group of pin sockets 2131 and the second group of pin sockets 2132 are symmetrically arranged around the first electrode post socket 2121. Each group of pin sockets includes a first pin socket 2133, a second pin socket 2134, and a third pin socket 2135. During connection, the pin 122 of the male connector 1 can be inserted into one of the pin insertion holes 213 , and the second electrode column 1242 can be inserted into one of the second electrode column insertion holes 2122 .
[0063] Furthermore, the electrode column socket 23 includes a first socket shell 231 and a first elastic sleeve 232 ; the first elastic sleeve 232 is installed at the inner top of the first socket shell 231 , and both the first socket shell 231 and the first elastic sleeve 232 are made of conductive metal material. Among them, the electrode post sockets 23 in the two second electrode post sockets 2122 are connected to the same wire, the pin socket 22 in the first pin socket 2133 of the first group of pin sockets 2131 and the pin socket 22 in the first pin socket 2133 of the second group of pin sockets 2132 are connected to the same signal line; the pin socket 22 in the second pin socket 2134 of the first group of pin sockets 2131 and the pin socket 22 in the second pin socket 2134 of the second group of pin sockets 2132 are connected to the same signal line; the pin socket 22 in the third pin socket 2135 of the first group of pin sockets 2131 and the pin socket 22 in the third pin socket 2135 of the second group of pin sockets 2132 are connected to the same signal line, so that the male connector 1 can be rotated 180 degrees forward and backward and can also be inserted into the female socket 2.
[0064] Furthermore, through holes are provided on the bottom cover 24 at positions corresponding to the electrode column socket 23 and the pin socket 22 , so that the electrode column socket 23 and the pin socket 22 can be connected to external wires, wherein the lower end of the electrode column socket 23 extends out of the bottom cover 24 .
[0065] Working principle of electrical connectors:
[0066] 1. Male and female seat docking guide
[0067] When the male connector 1 is inserted into the female socket 2, the first guide post 1231 and the second guide post 1232 are respectively inserted into the first guide post socket 2111 and the second guide post socket 2112. Precise positioning is achieved through the "symmetrical structure with the first electrode post 1241 as the center" (the first guide post 1231 and the second guide post 1232 are symmetrical, and the first guide post socket 2111 and the second guide post socket 2112 are symmetrical), ensuring that the first electrode post 1241 is inserted into the first electrode post socket 2121, the second electrode post 1242 is inserted into one of the second electrode post sockets 2122, and the first pin 1221, the second pin 1222, and the third pin 1223 are respectively inserted into the first pin socket 2133, the second pin socket 2134, and the third pin socket 2135 of one group of pin sockets.
[0068] 2. Conductive contact process
[0069] After the electrode column 124 is inserted into the electrode column insertion hole 212, it contacts the electrode column socket 23 in the hole. The first elastic sleeve 232 of the electrode column socket 23 is squeezed and deformed, and the elastic force tightly wraps the electrode column 124 to ensure stable electrical conduction.
[0070] After the pin 122 is inserted into the pin socket 213, it is connected to the pin sleeve 22. The bottom cover 24 fixes the electrode column sleeve 23 and the pin sleeve 22 to avoid poor contact and looseness.
[0071] 3. Collaborative reset and compatibility
[0072] When the male connector 1 is removed, the first spring sleeve 232 of the female connector 2 returns to its original position due to its own elasticity. The symmetrical structure of the female connector 2 (e.g., the symmetry of the first and second sets of pin sockets 2131 and 2132) allows the male connector 1 to be rotated 180° for insertion, improving ease of use while preventing damage to components caused by incorrect insertion.
[0073] The utility model discloses a connector male head and an electrical connector with a shock-absorbing and quick-return function, which relates to the field of electrical shock-absorbing connection technology, and solves the problem that the reset structure of the existing connector male head is prone to failure and reset jams when it is impacted. The key points of the technical solution are as follows: the connector male head includes a first shell, a plug-in part, an upper cover and a conical spring; the plug-in part is provided with an electrode column, a guide column and a pin, which is located in the inner cavity of the first shell and is movable, and has a first conical hole and a limiting column at both ends of the top; the upper cover is provided with a first limiting hole and a conical column at the corresponding position; the large end of the conical spring is sleeved on the conical column, and the small end is sleeved on the limiting column. The electrical connector includes a female socket and the above-mentioned male head. The utility model adopts a conical spring reset, which is faster and more accurate, avoids jamming or stuck, and has better elasticity and plug-in guide feedback, and is suitable for scenarios requiring stable electrical connections.
