Detailed Description
In order to make the technical solutions of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.
Without loss of generality, the embodiment takes the contactor accessory housing shown in the figures as a description object, and a housing structure scheme constructed based on the same parts is explained in detail. It should be understood that the outer contour of the accessory housing is designed according to the corresponding contactor, the inner contact mounting structure and the interlocking latch are not the core points of the present application, and the claimed contactor accessory housing is not substantially limited.
Referring to fig. 1 and 2, fig. 1 is a schematic view illustrating an assembled relationship of a contactor accessory casing according to the present embodiment, and fig. 2 is a sectional view of the contactor accessory casing according to the present embodiment after assembly, the sectional view being taken from a section i-i in fig. 1 to clearly illustrate a detachable connection relationship established based on a snap fit adapter pair.
The contactor accessory shell is composed of a first shell A and a second shell B which are oppositely buckled, and the first shell A and the second shell B are detachably connected through a clamping adaptation pair. The first shell A and the second shell B are of the same shell structure, and a first structure (1) and a second structure (2) which form a clamping adaptation pair are symmetrically arranged on a shell structure mounting surface in a connecting plane of the first shell A and the second shell B. The term "mounting surface" refers to the opposite surface of the two housing structures that are assembled and butted together, i.e., the surface that is located inside the body housing after assembly.
In this embodiment, the two housings (A, B) are of the same housing construction, i.e., the two housings assembled to each other are of the same component, for example, but not limited to, the main body of the housing construction and the assembly structure disposed thereon. By the arrangement, the product design and manufacturing cost of the accessory shell can be reduced, and the part classification management is facilitated on the basis of effectively reducing the product configuration cost; meanwhile, the mounting process steps are simplified, and the assembly manufacturability is good.
As shown in fig. 1 and 2, the first structure (1) and the second structure (2) constituting the snap-fit mating pair are arranged on the respective housing structure mounting surfaces in bilateral symmetry.
The first structure is an installation shaft 1 provided with a first boss 11, and the second structure is an installation hole 2 provided with a second boss 21. When the first housing a and the second housing B are buckled oppositely, the mounting shaft 1 on one can be inserted into the mounting hole 2 on the other, and the first boss 11 and the second boss 21 are clamped to form assembly limit when the mounting shaft is in the clamping state shown in fig. 2. Therefore, the detachable assembly between the two is realized, the occupation of the assembled clamping adaptation auxiliary space is less, and the whole structure is more compact.
It will be appreciated that the first formation in this embodiment is formed in the male mounting shaft 1 and the second formation is formed in the female mounting hole 2. Based on this cartridge block adaptation relation, this first structure also can adopt not to confine other evagination structures of installation axle to, correspondingly, this second structure can adopt not to confine other indent structures of mounting hole to as long as can establish the vice function needs that can dismantle the connection of block adaptation and satisfy two casings all.
In order to further improve the operability of the housing assembly, the fitting installation shaft 1 and the installation hole 2 can be additionally provided with a guide structure. Please refer to fig. 1, fig. 2 and fig. 3 together, wherein fig. 3 is an enlarged view of a portion ii of fig. 2.
Wherein, the end of the mounting shaft 1 is provided with a gradually-reduced clamping guide section 12, and a first boss 11 is formed at the position where the clamping guide section 12 is adjacent to the body of the mounting shaft 1; as shown, the body of the mounting shaft 1 is recessed, thereby forming a first boss 11 at a position adjacent to the engagement guide section 12.
Wherein, the hole of the mounting hole 2 has an engagement guide surface 22 matching with the engagement guide section 12, and the second boss 21 is formed at the position where the engagement guide surface 22 is adjacent to the hole wall of the mounting hole 2; as shown in the drawing, an engagement guide surface 22 is formed to radially project from the hole wall of the mounting hole 2, and thereby a second boss 21 is formed at a position adjacent to the engagement guide surface 22.
Along the cartridge lock direction, first boss 11 and second boss 21 in this scheme all are located corresponding block guide structure's downstream position. In this way, at the initial stage of the insertion, the engagement guide section 12 of the mounting shaft 1 and the engagement guide surface 22 of the mounting hole 2 function as an assembly guide, and the mounting shaft 1 is displaced and retracted based on the material characteristics until the first boss 11 adjacent to the engagement guide section 12 engages with the second boss 21 adjacent to the engagement guide surface 22, and the mounting shaft 1 in the engaged state is returned. The device has the characteristics of good operability, simple structure and reliable connection.
The engagement guide segment 12 shown in the drawings is circular truncated cone-shaped, and the engagement guide surface 22 is disposed as a slope in an axial cross section, and is easy to machine.
Of course, in other embodiments, the engagement guiding section 12 and the engagement guiding surface 22 may also have other adaptive shapes (not shown in the figures) according to the assembly requirements of the actual product, for example, but not limited to, the engagement guiding section may have a drum shape with a gradually protruding outer peripheral surface, and the engagement guiding surface may also have an outward convex arc surface.
In addition, the number of the clamping adaptation pairs can be set to be a plurality according to actual products, and correspondingly, the mounting shafts 1 and the mounting holes 2 are correspondingly arranged to be a plurality in a left-right symmetrical mode. In addition, at least part of the plurality of clamping adaptation pairs are staggered in the connecting plane of the first shell A and the second shell B; that is, some of the cards are not properly mated in a two-dimensional display arrangement. By the arrangement, on one hand, the available space of the internal structure of the shell is used for configuring the clamping adaptation pair, and the internal space of the shell can be fully utilized; meanwhile, the clamping adaptation pairs arranged in a staggered mode have good bearing capacity, and the assembling relation of the accessory shell is more reliable.
In addition to the aforementioned contactor accessory housing, the present embodiment also provides a contactor comprising a contactor housing and a contactor accessory housing as described above in connection therewith. It should be understood that other functions of the contactor are not the core invention of the present application and can be implemented by those skilled in the art based on the prior art, and therefore, will not be described herein.
Here, the contactor accessory housing can be assembled and connected with the contactor housing through the hook 3 on the connecting surface thereof, and modular installation can be realized.
The ordinal numbers "first" and "second" used herein are used only to describe a structure or acts of like function in the claims. It is to be understood that the use of the ordinal numbers "first" and "second" does not constitute an understandable limitation on the claimed technical solution.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that it is obvious to those skilled in the art that various modifications and improvements can be made without departing from the principle of the present invention, and these modifications and improvements should also be considered as the protection scope of the present invention.
