Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a wire end fixed connector. Background Technology

[0002] A connector is an electronic component used for the transmission and exchange of current or optical signals between devices in an electronic system. It is also known as a plug or connector. As a node, it transmits current or optical signals between devices, components, equipment, and subsystems, either independently or together with cables, while maintaining signal distortion and energy loss between systems. It is a fundamental component necessary for the connection of the entire complete system.

[0003] However, current connector housings and the internal resin blocks used to hold the terminals are basically integrally molded structures, making them impossible to disassemble. When the type of terminals needs to be changed, the entire connector must be replaced. Furthermore, connectors come in various sizes, making it impossible to replace only the resin portion and reuse the housing, resulting in high production costs. Utility Model Content

[0004] In order to overcome the shortcomings of existing technical solutions, this utility model provides a wire end fixed connector. By forming a detachable structure between the resin block inside the connector and the housing, it can effectively solve the technical problems that the connector housing is not universal and the terminal type inside the connector cannot be flexibly adjusted.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A wire-end fixed connector includes a housing, a resin block, and a terminal. One end of the terminal is inserted into the resin block for encapsulation and fixation. The resin block is installed inside the housing to fix the position of the terminal. The housing consists of a first outer shell and a second outer shell. The first outer shell and the second outer shell are tightly fitted at one end and fixed by a locking block. The end of the first outer shell away from the second outer shell has a raised first annular portion, and the end of the second outer shell away from the first outer shell has a raised second annular portion. The interiors of the first annular portion and the second annular portion are conductive and used to install a removable resin block. The end of the resin block facing the first outer shell is the positive terminal, and the end of the resin block facing the second outer shell is the negative terminal. One end of the terminal is inserted from the positive terminal of the resin block, and the negative terminal of the resin block has a socket for connection with the corresponding terminal after insertion.

[0007] Furthermore, the card block is integrally connected to one end of the first outer shell, and the second outer shell is provided with a card slot for inserting and fixing the card block.

[0008] Furthermore, the first annular portion has an inwardly bent first anti-detachment portion at the end away from the first outer shell, which is used to fix the position of the positive end of the resin block. The second annular portion has an inwardly bent second anti-detachment portion at the end away from the second outer shell, which is used to fix the position of the negative end of the resin block.

[0009] Furthermore, the first annular portion is provided with a first anti-mistake part connected to the resin block, and the second annular portion is provided with a second anti-mistake part connected to the resin block.

[0022] 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.

[0023] like Figure 1-5 As shown, this utility model provides a wire-end fixed connector, mainly used to raise and fix the connector before it is used as a wire terminal. Its specific structure mainly includes a housing 1, a resin block 2, and terminals 3. One end of the terminal 3 is inserted into the resin block 2 for encapsulation and fixation. The resin block 2 is installed inside the housing 1 to fix the position of the terminal 3. Multiple terminals 3 have one end inserted into the resin block 2 for fixation, and the resin block 2 forms a partial encapsulation and fixation structure for the terminals 3. The resin block 2, installed inside the housing 1, forms a detachable structure, facilitating the replacement of resin blocks 2 with different types of terminals 3, allowing the housing 1 to be recycled, and reducing production costs.

[0024] To facilitate assembly with the resin block 2 and form a detachable structure, the housing 1 consists of a first outer shell 101 and a second outer shell 102. The two outer shells, when joined, fix the resin block 2 installed inside. When the first outer shell 101 and the second outer shell 102 are connected, one end of each is tightly fitted and initially secured by two locking blocks 4. The locking block 4 is located at one end of the first outer shell 101, and correspondingly, the second outer shell 102 has a slot 5 for inserting the locking block 4. The locking block 4 and the slot 5 are sized to match, and once the locking block 4 is fixed within the slot 5, the connection between the first outer shell 101 and the second outer shell 102 after fitting together can be initially secured.

[0025] A through fixing hole 12 is provided at both ends of the first housing 101 and the second housing 102. After the connector is installed through the fixing hole 12, on the one hand, the connection between the first housing 101 and the second housing 102 can be strengthened and locked, and on the other hand, the connector can be fixed in the panel or other positions in advance through the fixing hole 12, and then wiring can be performed, which is more convenient to use.

[0026] After the first outer shell 101 and the second outer shell 102 are connected, the end of the first outer shell 101 away from the second outer shell 102 has a protruding first annular portion 6, and the end of the second outer shell 102 away from the first outer shell 101 has a protruding second annular portion 7. The interiors of the first annular portion 6 and the second annular portion 7 are connected and used to install the resin block 2. At this time, the space formed by the internal connection of the first annular portion 6 and the second annular portion 7 is the position for installing the resin block 2. That is to say, one end of the resin block 2 is installed in the first annular portion 6, and the other end is installed in the second annular portion 7, and then fixed by the first outer shell 101 and the second outer shell 102 being attached together.

[0027] When the resin block 2 is installed in the first annular portion 6 and the second annular portion 7, the first annular portion 6 is provided with a first anti-misplacement portion 10 connected to the resin block 2, and the second annular portion 7 is provided with a second anti-misplacement portion 11 connected to the resin block 2. The first anti-misplacement portion 10 and the second anti-misplacement portion 11 can not only prevent blind insertion, but also enhance the stability of the resin block 2 in the first annular portion 6 and the second annular portion 7, and prevent movement and detachment.

[0028] To further reinforce the position of the resin block 2, a first anti-detachment part 8 with an inward bend is provided at the end of the first annular portion 6 away from the first outer shell 101. Similarly, a second anti-detachment part 9 with an inward bend is provided at the end of the second annular portion 7 away from the second outer shell 102. After the two anti-detachment parts are bent inward, they form an opening smaller than the side of the resin block 2, which can further reinforce the position of the resin block 2 and prevent the resin block 2 from falling off.

[0029] After the resin block 2 is installed inside the housing 1, the end of the resin block 2 facing the first housing 101 is the positive terminal, and the end of the resin block 2 facing the second housing 102 is the negative terminal. At this time, the terminal 3 inserted into the resin block 2 is inserted from the positive terminal, and the end of the terminal 3 away from the resin block 2 extends outward for connection with other wires. The negative terminal of the resin block 2 is provided with a socket 201 for connection with the corresponding terminal 3 after insertion. This socket 201 is used for connection with the male end of other wires. After the male end of other wires is inserted along the socket 201, it connects with the internal terminal of the resin block 2.

[0030] Compared with traditional technologies, the connector provided by this technical solution is internally detachable. The housing 1 and the tree finger block 2 with the terminal 3 inserted can be freely assembled. During use, the type of terminal 3 can be adjusted by replacing the internal resin block 2 without replacing the housing 1. The housing 1 can be recycled, reducing production costs. The resin block 2 is clamped between the two outer shells of the housing 1, making assembly convenient and flexible.

[0031] 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.
