[0004] The purpose of this invention is to provide a wire-to-board connector to solve the problems mentioned in the background art. Current wire-to-board connectors are simply plug-in connections. After plugging, the lack of a limiting structure can lead to loosening, affecting subsequent signal transmission. In addition, the small contact area at the contact point can cause poor contact.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a wire-to-board connector, comprising a female end shell and a male end shell. A blocking end block is fixedly disposed at one end of the female end shell. Limiting slots are symmetrically formed on the outer edge of the female end shell. Insertion slots are evenly distributed on the end of the female end shell away from the blocking end block. Through slots are evenly distributed on the end of the female end shell away from the insertion slot. An auxiliary side block is fixedly disposed on the outer edge of the male end shell. A guide frame is obliquely fixedly disposed at one end of the male end shell. A side fixing block is fixedly installed on the outer side of the male end shell, and a fixing through hole is opened at one end of the side fixing block. Limiting strips are fixedly installed horizontally and evenly on the inner side of the channel of the male end shell. End locking holes are evenly opened on the male end shell at the end away from the channel opening. The main metal head is fixedly locked horizontally on the inner side of the end locking hole. An inner metal block is fixedly locked horizontally on the inner side of the through slot. A limiting inclined groove is opened on the inner side wall of the insertion slot. A locking inclined block is symmetrically arranged on the outer side of the main metal head.
[0006] Preferably, both the female end shell and the male end shell are made of insulating material, and one end of the female end shell is inserted into the groove at one end of the male end shell. The blocking end block is fixedly installed on the outer side of one end of the female end shell, and the side of the blocking end block is connected to the side of the guide frame.
[0007] Preferably, the limiting slots are symmetrically and parallel to each other on the four outer sides of the female end shell, and one end of the limiting slot horizontally penetrates the end of the female end shell away from the blocking end block, with the penetrating end being open.
[0008] Preferably, the interior of the insertion slot and the interior of the through slot are connected in a one-to-one correspondence, the auxiliary side block is fixedly installed on the outer side of the male end shell near one end, and the guide frame is fixedly installed in a trumpet shape at the edge of the opening end of the male end shell.
[0009] Preferably, the fixed through hole is opened through the central axis of the side fixing block, the number of limiting clips is consistent with the number of limiting slots, and the side of the limiting clip is horizontally corresponding to the inner side of the limiting slot. The number and arrangement of the end locking holes are consistent with the insertion through slot.
[0010] Preferably, one end of the main metal head is horizontally and through-connected to the inner side of the insertion slot, and the extension end is connected to the inner side of the inner metal block to maintain electrical connection. One end of each locking oblique block is correspondingly locked to the inner side of the limiting oblique slot.
[0011] Compared with the prior art, the beneficial effects of this utility model are: This wire-to-board connector features a unique design with a locking bevel, resulting in a larger contact area between the main metal head and the inner metal block during daily use. This larger contact area reduces contact resistance, minimizes power loss, and improves electrical transmission efficiency. During electronic equipment operation, it ensures stable current and signal transmission, preventing issues like overheating and signal attenuation caused by a small contact area, thus guaranteeing the normal operation and performance of the electronic equipment. The wire-to-board connector's design ensures connection stability through multiple aspects. The locking strip and locking slot effectively prevent the female end shell from wobbling within the male end shell, avoiding poor contact caused by movement. Simultaneously, the locking bevel on the main metal head engages with the locking bevel on the inner wall of the insertion slot, further enhancing the connection stability between the main metal head and the inner metal block, making the electrical connection more reliable, reducing signal interference or circuit failures caused by loose connections, and improving the operational stability and reliability of the electronic equipment. The entire wire-to-board connector has a compact structure and a rational layout of its components. Both the female and male housings are made of insulating materials, ensuring electrical safety while reducing the connector's size. The inclusion of limiting slots, limiting strips, insertion slots, and through slots maximizes space utilization, enabling stable connection and good electrical transmission within a limited space, making it suitable for space-constrained electronic devices. The flared guide frame provides excellent guidance when inserting the female housing into the male housing. Operators do not need to spend excessive time and effort on precise alignment; simply aligning the female housing roughly with the opening of the male housing, guided by the guide frame, allows for smooth insertion, significantly improving installation efficiency. Furthermore, the fixing through holes on the auxiliary side blocks and side fixing blocks facilitate installation and fixation, allowing the connector to be securely mounted on equipment according to actual needs. This wire-to-board connector design offers versatility, adapting to different circuit board and cable connection requirements. By adjusting the specifications and layout of components such as the main metal head and inner metal block, it can meet different current and signal transmission requirements, making it widely applicable in various electronic devices such as computers, communication equipment, and home appliances, demonstrating strong market adaptability and application prospects.

[0020] The unique design of the locking wedge 16 increases the contact area between the main metal head 13 and the inner metal block 14. This larger contact area reduces contact resistance, minimizes power loss, and improves electrical transmission efficiency. During the operation of electronic equipment, this ensures stable transmission of current and signals.
[0021] Working principle: First, install the female end shell 1 and the male end shell 6 onto the corresponding circuit boards and cable ends, respectively. The female end shell 1 is made of insulating material, and a blocking end block 2 is fixedly installed at one end. The blocking end block 2 is located on the outer side of one end of the female end shell 1, and plays a certain positioning and blocking role. The outer side of the female end shell 1 has symmetrical limit slots 3. These limit slots 3 are parallel and symmetrically distributed on the four outer sides of the female end shell 1, and one end of them horizontally penetrates the end of the female end shell 1 away from the blocking end block 2, and is open, so as to facilitate subsequent snap-fit with the male end shell 6. Meanwhile, the female end shell 1 has evenly spaced insertion slots 4 at the end away from the blocking end block 2, and evenly spaced through slots 5 at the end away from the insertion slots 4. The insertion slots 4 and through slots 5 are aligned one-to-one to provide a channel for electrical connection. The male end shell 6 is also made of insulating material, and an auxiliary side block 7 is fixedly installed on its outer side. The auxiliary side block 7 is located on the outer side of the male end shell 6 near one end, providing an auxiliary operating point during installation. A guide frame 8 is obliquely fixed to one end of the male end shell 6. The guide frame 8 is funnel-shaped and fixed to the edge of the open end of the male end shell 6, serving as a guide during insertion, allowing the female end shell 1 to be inserted into the male end shell 6 more smoothly. A side fixing block 9 is also fixedly installed on the outer side of the male end shell 6. One end of the side fixing block 9 has a fixing through hole 10, through which the male end shell 6 can be fixed to the corresponding equipment. Limiting strips 11 are horizontally and evenly fixedly installed on the inner side of the channel of the male end shell 6. The number of limiting strips 11 is consistent with the number of limiting slots 3 on the female end shell 1. End locking holes 12 are evenly opened on the end of the male end shell 6 away from the channel opening. The number and arrangement of the end locking holes 12 are consistent with the insertion slots 4 on the female end shell 1.
[0022] During the connection operation, align the end of the female housing 1 with the insertion slot 4 with the opening end of the channel of the male housing 6. Guided by the guide frame 8, the female housing 1 is gradually inserted into the channel of the male housing 6. As insertion proceeds, the limiting strip 11 on the inner side of the channel of the male housing 6 will horizontally engage with the inner side of the limiting slot 3 on the outer side of the female housing 1, achieving initial positioning and fixation to prevent the female housing 1 from shaking inside the male housing 6.
[0023] When the female end housing 1 is inserted into the appropriate position, the main metal head 13, which is horizontally fixed and locked inside the locking hole 12 on the upper end of the male end housing 6, will horizontally and through-insert into the inner side of the insertion slot 4 of the female end housing 1. Furthermore, the extended end of the main metal head 13 will insert into the inner side of the inner metal block 14, which is horizontally fixed and locked inside the through slot 5 on the female end housing 1, thus achieving electrical connection. At this time, the locking angled blocks 16 symmetrically arranged on the outer side of the main metal head 13 will correspondingly lock into the inner side of the limiting angled groove 15 opened on the inner wall of the insertion slot 4. The locking of the locking angled blocks 16 not only increases the contact area between the main metal head 13 and the inner metal block 14, ensuring a good electrical connection, but also, under the locking action of the groove, makes it difficult for the main metal head 13 to detach from the inner metal block 14, ensuring the stability of the connection.
