DETAILED DESCRIPTION

[0031] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the accompanying drawings. The accompanying drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0032] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0034] Please refer to Figure 1-Figure 7 , is a multi-connector 100 described in an embodiment, which includes a board end component 10, the board end component 10 includes a board end seat 11 and a board end terminal 12, the board end terminal 12 is inserted into the board end seat 11; and a wire end component 20, the wire end component 20 includes a wire end seat 21 and a wire end terminal 22, the wire end terminal 22 is inserted into the wire end seat 21, the wire end terminal 22 is provided with a convex bulge 221, a connecting spring piece 222 and a reinforcing spring piece 223, the convex bulge 221 and the connecting spring piece 222 are surrounded by a connecting hole, and the reinforcing spring piece 223 and the connecting spring piece 222 are stacked.

[0035] After the board-end assembly 10 and the line-end assembly 20 are plugged and assembled, the board-end terminal 12 is inserted into the connection hole and is in electrical contact with the convex bump 221 and the connection spring sheet 222 .

[0036] The implementation of the embodiments of the utility model will have the following beneficial effects: the multi-connector 100 of the present scheme is composed of a board end component 10 and a line end component 20 that are plugged in and matched. Since the line end terminal 22 is provided with a convex bump 221 and a stacked connecting spring piece 222 and a reinforcing spring piece 223, after the end of the board end terminal 12 is inserted into the connecting hole, one side can be clamped with the convex bump 221, and the other side can be elastically abutted with the connecting spring piece 222, and the reinforcing spring piece 223 increases the contact force between the connecting spring piece 222 and the board end terminal 12, so that the convex bump 221 and the connecting spring piece 222 can continuously and reliably clamp the board end terminal 12, thereby avoiding the problem of poor contact caused by the loosening of the board end terminal 12 and the line end terminal 22 due to insufficient elastic pressing force during long-term use, ensuring the connection quality of the board end component 10 and the line end component 20, and avoiding affecting the signal transmission quality of the multi-connector 100.

[0037] The convex bump 221 is a boss-like structure protruding toward the connection hole and is made by stamping or other processes. The surface of the convex bump 221 is an arc surface structure to avoid scratches when the board terminal 12 is inserted and affect the electrical connection quality with the line terminal 22.

[0038] The connecting spring piece 222 and the reinforcing spring piece 223 are preferably made of metal material to obtain better elastic performance. The connecting spring piece 222 and the reinforcing spring piece 223 can be integrally formed or detachably assembled. For example, in this embodiment, the reinforcing spring piece 223 is integrally connected to the surface of the connecting spring piece 222 by welding to obtain better elasticity and overall structural performance.

[0039] In one embodiment, the connecting spring piece 222 and the reinforcing spring piece 223 are both bent toward the convex bump 221. It can be understood that the connecting spring piece 222 and the reinforcing spring piece 223 are both formed into a quasi-L-shaped structure, and the bent portion arranged toward the convex bump 221 can obtain a greater elastic contact force, so that it can be tightly pressed with the board terminal 12, and it is not easy to cause plastic deformation and give way to affect the contact reliability.

[0040] In addition, the contact mode between the connecting spring piece 222 and the board terminal 12 is line contact or small-area surface contact, which has small friction resistance to the board terminal 12, improves the installation smoothness of the board terminal 12, and reduces the insertion force.

[0041] In another embodiment, a foolproof fin 224 is protruded outwardly on one side in the width direction of the line terminal 22, and the line terminal seat 21 is provided with a foolproof groove, and the foolproof fin 224 is inserted into the foolproof groove. When the line terminal 22 is inserted into the line terminal seat 21, the line terminal 22 is in a correct posture so that the foolproof fin 224 can be aligned and inserted into the foolproof groove, thereby preventing the problem of the line terminal 22 being installed upside down.

[0042] See also Figure 4 and Figure 6 Furthermore, in order to improve the installation stability of the wire end terminal 22 in the wire end seat 21, in another embodiment, the wire end assembly 20 also includes a wire end fixing piece 23, the wire end seat 21 is recessed with a socket 211, and the wire end fixing piece 23 is inserted into the socket 211 and presses and fixes the wire end terminal 22.

[0043] According to actual needs, the multi-connector 100 can be designed as a single-row form or a double-row form. The single-row form specifically refers to that the board-end terminals 12 and the line-end terminals 22 adopt multiple single-row structures, and the double-row form specifically refers to that the board-end terminals 12 and the line-end terminals 22 adopt multiple double-row structures. In one embodiment, when there are multiple line-end terminals 22 and they are arranged in a single row, the line-end fixing member 23 is provided with a first pressing portion; when there are multiple line-end terminals 22 and they are arranged in two rows, the line-end fixing member 23 is provided with a first pressing portion and a second pressing portion arranged in an upper and lower manner, and the first pressing portion and the second pressing portion respectively press the corresponding row of line-end terminals 22. Therefore, according to the arrangement structure of the line-end terminals 22, the line-end fixing member 23 can press and fix all the line-end terminals 22.

[0044] In another embodiment, at least one side wall in the width direction of the socket 211 is further provided with a card body 211a, and at least one side wall in the width direction of the wire end fixing piece 23 is provided with a pre-fixing card protrusion 231 and a final fixing card protrusion 232. The pre-fixing card protrusion 231 and the final fixing card protrusion 232 are arranged in layers along the insertion direction of the wire end fixing piece 23. As the wire end fixing piece 23 is inserted into the socket 211, the pre-fixing card protrusion 231 and the final fixing card protrusion 232 are successively engaged with the card body 211a.

[0045] During installation, the wire end fixing piece 23 is inserted into the socket 211, and the pre-fixing protrusion 231 is engaged with the card body 211a. At this time, the wire end fixing piece 23 only preliminarily presses the wire end terminal 22, and the wire end terminal 22 still has freedom, so as to facilitate position adjustment and eliminate the installation position error and the docking error with the board end terminal 12. After the adjustment is completed, the wire end fixing piece 23 is further pressed down, and the final fixing protrusion 232 is engaged with the card body 211a. The wire end fixing piece 23 completely presses and fixes the wire end terminal 22, thereby preventing the wire end terminal 22 from being displaced and loosened under vibration or external force.

[0046] In addition, in order to ensure that the board terminal 12 is installed firmly and not easily displaced or loosened under the action of external force, in one embodiment, at least one side of the board terminal 12 in the width direction is provided with an anti-dropping tooth 121, and the board terminal seat 11 is provided with a socket, and the board terminal 12 is inserted into the socket, and the anti-dropping tooth 121 is fixedly engaged with the hole wall of the socket.

[0047] Preferably, anti-dropout teeth 121 are provided on opposite sides of the board-end terminal 12 in the width direction, and the number of anti-dropout teeth 121 provided on each side is more than one. When more than two anti-dropout teeth 121 are provided on each side, the anti-dropout teeth 121 are arranged at intervals along the insertion direction of the board-end terminal 12 to further improve the bite force between the board-end terminal 12 and the hole wall of the socket, thereby improving the installation stability.

[0048] In order to assemble the board end assembly 10 with the circuit board 200 and ensure the connection strength, in one embodiment, the board end assembly 10 also includes a first board end fixing member 13 and a second board end fixing member 14, and the first board end fixing member 13 and the second board end fixing member 14 are respectively arranged on both sides of the width direction of the board end seat 11; wherein, the first board end fixing member 13 is provided with a pin 131, and the pin 131 is used to insert into the mounting through hole of the circuit board 200, and the second board end fixing member 14 is provided with a supporting foot 141, and the supporting foot 141 is used to support the board surface of the circuit board 200.

[0049] It can be understood that the first board end fixing member 13 and the second board end fixing member 14 are of different structures, so that the first board end fixing member 13 and the second board end fixing member 14 are assembled with the circuit board 200 in different ways. Of course, in other embodiments, the first board end fixing member 13 and the second board end fixing member 14 can also be of the same structural design, for example, both have the pins 131 or both have the support feet 141.

[0050] In another embodiment, the outer walls on opposite sides of the board end seat 11 in the width direction are provided with mounting grooves 111, and the side walls in the width direction of the first board end fixing piece 13 and the second board end fixing piece 14 are provided with stopping teeth 15, the first board end fixing piece 13 and the second board end fixing piece 14 are respectively inserted into the corresponding mounting grooves 111, and the stopping teeth 15 are engaged with the groove walls of the mounting grooves 111. On the one hand, the structural design of the installation groove 111 allows the first board end fixing member 13 and the second board end fixing member 14 to be inserted into the installation groove 111 by inserting from top to bottom, and the installation method is simple and feasible. On the other hand, the locking teeth 15 are engaged with the groove wall of the installation groove 111, which can effectively improve the installation strength of the first board end fixing member 13 and the second board end fixing member 14, so that the first board end fixing member 13 and the second board end fixing member 14 can be firmly and reliably installed on the board end seat 11.

[0051] In order to improve the installation progress and installation stability of the first plate end fixing member 13 and the second plate end fixing member 14 in the installation groove 111, in one embodiment, the groove wall of the installation groove 111 is provided with at least one first positioning step, and the first plate end fixing member 13 and the second plate end fixing member 14 are both provided with at least one second positioning step 16, and the second positioning step 16 is clamped and positioned with the first positioning step.

[0052] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent application. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
