Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a pin socket for an electrical connector. Background Technology

[0002] The pin socket (terminal socket or connector socket) of an electrical connector is the core component used for electrical connection. It usually consists of an insulating base and metal pins, responsible for transmitting signals or electricity and providing mechanical fixation. There are various types, such as straight pins, bent pins, pin headers, or waterproof interfaces with housings.

[0003] Traditional electrical connector pin sockets rely on a combination of mechanical and electrical connections to achieve their function. The pins of the pin socket are precisely designed in shape and size to match the corresponding socket holes. However, lacking internal structural reinforcement, the pin sockets can deform or even be damaged when subjected to external forces. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a pin holder for electrical connectors, which aims to improve the traditional pin holders of electrical connectors, which are prone to deformation or even damage due to the lack of internal structural reinforcement.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A pin holder for an electrical connector includes a locking block, the outer wall of which is provided with a protective component, the interior of which has a slide rail, and a support column is fixedly connected inside the protective component.

[0007] Preferably, the protective component includes a wear-resistant layer, and the outer wall of the wear-resistant layer is sequentially connected to an electromagnetic shielding layer, an insulating layer, and a base layer.

[0008] Preferably, a first spring is provided inside the card block, and a sliding block is provided on the outer wall of the first spring.

[0009] Preferably, the outer wall of the sliding block is slidably connected to the interior of the protective component.

[0010] Preferably, the protective component is internally fixedly connected to a first fixing plate, and the outer wall of the first fixing plate is rotatably connected to a second fixing plate.

[0011] Preferably, a baffle is fixedly connected to the outer wall of the second fixing plate, a second spring is provided on the outer wall of the baffle, and a connecting rod is provided inside the second spring.

[0012] Preferably, the outer wall of the second spring is provided with a sliding plate, and a support rod is fixedly connected to the upper surface of the sliding plate. The outer wall of the support rod is slidably connected to the inside of the protective assembly.

[0013] Preferably, the inner side of the sliding plate is slidably connected to the outer wall of the connecting rod, and the outer wall of the connecting rod is fixedly connected to the outer wall of the baffle.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the wear-resistant layer supports the electromagnetic shielding layer for fixation, and then the insulation layer is fixed along with the electromagnetic shielding layer. Subsequently, the base layer is fixed under the action of the insulation layer, which can ultimately achieve the purpose of strengthening the internal structure of the needle holder and effectively improve the needle holder's resistance to external forces. When faced with the pulling force and pressure during insertion and removal, as well as the vibration and impact during equipment operation, the needle holder is not easily deformed or damaged.

[0016] 2. In this utility model, the first spring is compressed by squeezing the sliding block, and then the sliding plate is rotated by rotating the support rod. Subsequently, the connecting rod will rotate with the rotation of the sliding plate. Finally, the purpose of quick connection and prevention of loosening can be achieved. It can provide strong fixing force after the needle seat is inserted to prevent the connection from loosening due to external pulling or vibration. Attached Figure Description

[0024] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Reference Figures 1-3 The present invention provides an embodiment of a pin holder for an electrical connector, comprising a locking block 1, a protective component 2 provided on the outer wall of the locking block 1, a slide rail 3 provided inside the protective component 2, and a support column 4 fixedly connected inside the protective component 2.

[0026] Specifically, the protective component 2 is used to support the locking block 1 for fixation. The locking block 1 is used to ensure that the pin socket is stably connected to the corresponding plug. The protective component 2 has a slide 3 inside. The slide 3 can ensure that the pin is accurately aligned with the socket, avoiding the pin bending, damage or poor contact caused by misalignment during insertion and removal. The protective component 2 is used to support the support column 4 for fixation.

[0027] Reference Figures 2-4 The protective component 2 includes a wear-resistant layer 201, and an electromagnetic shielding layer 202, an insulating layer 203, and a base layer 204 are sequentially connected to the outer wall of the wear-resistant layer 201; a first spring 5 is provided inside the locking block 1, and a sliding block 6 is provided on the outer wall of the first spring 5; the outer wall of the sliding block 6 is slidably connected to the inside of the protective component 2.

[0028] Specifically, the wear-resistant layer 201 effectively resists wear caused by friction and slows down the wear rate of the needle holder surface material. The electromagnetic shielding layer 202 can block the influence of external electromagnetic interference on the internal signal transmission and also prevent the electromagnetic signals generated internally from leaking out and interfering with other equipment. The insulation layer 203 can prevent short circuits between pins and between pins and the outer shell, ensuring electrical safety. The needle holder shell needs to have good insulation performance. The base layer 204 can provide basic mechanical strength and shape support, enabling the needle holder to maintain its structural integrity and protect key components such as internal pins. This can achieve the effect of strengthening the internal structure of the needle holder and making the needle holder less prone to deformation and damage.

[0029] Reference Figure 3 and Figure 5The protective component 2 is internally fixedly connected to a first fixing plate 7, and the outer wall of the first fixing plate 7 is rotatably connected to a second fixing plate 8; the outer wall of the second fixing plate 8 is fixedly connected to a baffle 9, the outer wall of the baffle 9 is provided with a second spring 10, and the inner wall of the second spring 10 is provided with a connecting rod 13; the outer wall of the second spring 10 is provided with a sliding plate 11, the upper surface of the sliding plate 11 is fixedly connected to a support rod 12, and the outer wall of the support rod 12 is slidably connected to the inside of the protective component 2; the inner wall of the sliding plate 11 is slidably connected to the outer wall of the connecting rod 13, and the outer wall of the connecting rod 13 is fixedly connected to the outer wall of the baffle 9;

[0030] Specifically, firstly, the sliding block 6 is squeezed to compress the first spring 5. Then, the rotating support rod 12 is used to rotate the sliding plate 11. The sliding plate 11 is used to rotate the second spring 10. The sliding plate 11 is used to rotate the connecting rod 13. The connecting rod 13 is used to rotate the baffle 9. The baffle 9 is used to rotate the second fixing plate 8. The first fixing plate 7 is used to support the rotation of the second fixing plate 8. The first fixing plate 7 is fixed inside the protective component 2. The connecting rod 13 is used to fix the interface to prevent shaking. This can achieve the effect of quick connection and prevent loosening. It can prevent the connection from becoming loose due to external pulling or vibration.

[0031] Working principle: When the pin socket of the electrical connector needs to be used, the wear-resistant layer 201 supports and fixes the electromagnetic shielding layer 202, thereby fixing the insulating layer 203 to the outer wall of the electromagnetic shielding layer 202, which in turn drives the base layer 204 to be fixed to the outer wall of the insulating layer 203. This can achieve the effect of strengthening the internal structure of the pin socket. When facing the pulling force and pressure during insertion and removal, as well as the vibration and impact during equipment operation, the pin socket is not easy to deform or be damaged.

[0032] The interface squeezes the sliding block 6, which in turn compresses the first spring 5. Then, the rotating support rod 12 drives the sliding plate 11 to slide, thereby causing the connecting rod 13 to rotate. At the same time, the second spring 10 rotates, causing the baffle 9 to rotate, which in turn drives the second fixing plate 8 to rotate. This fixes the second fixing plate 8 inside the protective component 2, thus achieving a quick connection and preventing loosening. It can provide a strong fixing force after the needle seat is inserted, preventing the connection from becoming loose due to external pulling or vibration.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
